## Legendary Wildlife Cameraman Doug Allan Dies at 74 in Nepal

Doug Allan, one of the most celebrated wildlife cameramen in television history, has passed away after experiencing a medical emergency during a trekking expedition in Nepal. The Scottish filmmaker, who dedicated his life to capturing the planet's most breathtaking and remote environments on camera, was 74 years old.

### What Happened in Nepal

According to local tourist police and hospital officials, Allan began experiencing severe breathing difficulties on the very first day of his trek near the Dhampus region, shortly after setting out toward Annapurna base camp — the starting point for climbers approaching the world's tenth-highest mountain at 8,091 metres (26,545 feet). He was swiftly transported to Care Mark Hospital in the city of Pokhara before being transferred to Manipal Hospital, where he arrived in a critical condition. He passed away the following day, on Wednesday.

## A Career That Defined Wildlife Filmmaking

Born in Dunfermline, Fife, in 1951, Allan's fascination with the natural world was ignited at an early age by Jacques Cousteau's groundbreaking 1956 underwater documentary, *The Silent World*. That early spark of curiosity ultimately shaped an extraordinary career spanning several decades.

After earning a degree in marine biology from the University of Stirling, Allan took on various diving roles before landing a pivotal position as a research diver with the British Antarctic Survey, based at Signy Island in the South Orkney Islands. It was in those icy, remote waters that his passion for visual storytelling truly took hold.

### The Meeting That Changed Everything

In 1981, a chance encounter with Sir David Attenborough opened the door to what would become one of the most celebrated partnerships in nature documentary history. Allan went on to work on the landmark series *Living Planet*, portions of which were filmed in Antarctica. Inspired by the experience, he purchased a 16mm cine camera and filmed Emperor penguins himself, later selling the footage to the BBC — a move that effectively launched his professional filmmaking career.

From that point forward, Allan established himself as the go-to cinematographer for extreme environments, particularly in polar regions and underwater settings. He served as principal cameraman on some of the BBC's most iconic nature productions, including *The Blue Planet*, *Planet Earth*, and *Frozen Planet*, all produced alongside Sir David Attenborough.

## Awards and Recognition

Over the course of his remarkable career, Doug Allan accumulated an impressive array of honours:

- **Eight Emmy Awards** for outstanding contributions to wildlife filmmaking
- **Five BAFTA Awards** recognising excellence in television craft
- **Honorary Fellowship** of the Royal Photographic Society
- **The Polar Medal** — awarded twice — for his work in the world's most extreme polar environments
- **BAFTA Scotland's Outstanding Contribution to Craft prize** in 2017
- **OBE** for services to broadcast media and environmental awareness, awarded in 2024

## Close Encounters and Unforgettable Moments

Allan's work frequently placed him in extraordinarily dangerous situations. In 2017, he recalled spending approximately 620 days of his life tracking and filming polar bears. On one memorable occasion, he looked up to find a polar bear pressing its wet nose against the window where he was sheltering — a moment he described with characteristic humour and wonder.

On another occasion, while filming underwater, a hungry walrus mistook him for a seal and grabbed hold of his legs. Allan managed to drive the animal away by striking it on the head with his camera — a testament to both his composure and his commitment to getting the shot.

## A Voice for the Environment

In his later years, Allan channelled his lifelong love of the natural world into environmental advocacy. Earlier in 2024, he publicly called on the Scottish government to support an "ecocide" bill that would hold corporations legally accountable for causing severe or widespread damage to ecosystems. His voice carried significant weight, given his decades of first-hand experience witnessing environmental change in the world's most fragile habitats.

## Tributes Pour In

Allan's management company, Jo Sarsby Management, released a heartfelt statement describing him as "a true pioneer of wildlife filmmaking" whose visual legacy "few could ever match."

"His work brought audiences closer to the wonders of our planet, inspiring awe, understanding and deep respect for the natural world," the statement read. "He was a true gentleman and will be profoundly missed."

His ex-wife, fellow wildlife photographer Sue Flood OBE, also paid tribute on social media, describing the profound influence Allan had on her life and career. She noted it was "of comfort to know that he was doing something adventurous with a dear friend" when he passed, and said she would remember him "with deep affection, respect and gratitude for a lifetime of memories."

Doug Allan leaves behind an unparalleled visual record of our planet's wildest places — a gift to generations of nature lovers and a lasting monument to a life lived with extraordinary courage, curiosity, and passion.

## Your Genetic Code Is Hiding Something Scientists Just Figured Out

Not every instruction written into your DNA carries the same weight — and now researchers finally understand why. A groundbreaking discovery has revealed that human cells possess a sophisticated internal system capable of identifying weaker genetic instructions and quietly shutting them down. At the center of this mechanism is a protein called DHX29, which acts as a molecular gatekeeper, recognizing inefficient genetic messages and suppressing them before they can cause problems.

This discovery exposes an entirely new layer of control within gene regulation — one that has been hiding in plain sight inside the genetic code itself.

## Understanding the Building Blocks: Codons and Why They Matter

Human DNA is constructed from long chains of three-letter units, each composed of four possible nucleotides. These units — called codons — serve as instructions that tell cells which amino acids to assemble when producing proteins. Interestingly, multiple different codons can encode the exact same amino acid, a feature that scientists historically dismissed as simple biological redundancy.

But that interpretation is now being challenged. Growing evidence suggests these so-called synonymous codons are far from interchangeable. Some codons produce highly stable mRNA molecules that cells can translate into proteins with ease, making them efficient workhorses. Others, labeled non-optimal codons, generate weaker messages that are harder to translate and more prone to degradation. What remained unclear — until now — was precisely how human cells identify and respond to these inferior instructions.

## The Research: Hunting Down the Cell's Quality Control Mechanism

A collaborative research team from Kyoto University and RIKEN, led by scientists Osamu Takeuchi and Takuhiro Ito, set out to answer that question through a carefully designed series of experiments.

The team launched a genome-wide CRISPR screening process to pinpoint which molecular factors influence codon-dependent gene expression. The results consistently pointed toward an RNA-binding protein known as DHX29. To confirm its role, the researchers conducted RNA sequencing analysis, which revealed a telling pattern: when DHX29 was absent from cells, mRNA molecules carrying non-optimal codons accumulated in significantly higher quantities than normal.

### How DHX29 Identifies and Silences Weak Genetic Messages

To understand the mechanics of how DHX29 operates, the team turned to cryo-electron microscopy, a powerful imaging technique that allowed them to observe the protein interacting directly with the 80S ribosome — the cellular machine responsible for translating genetic instructions into proteins. Further analysis using selective ribosome profiling confirmed that DHX29 preferentially associates with ribosomes that are actively reading non-optimal codons.

Additional proteomic investigation uncovered the next step in the process. DHX29 recruits a protein complex known as GIGYF2•4EHP, which then acts to selectively suppress the mRNA molecules containing those weaker codon sequences. The result is a targeted reduction in the production of inefficient genetic messages.

"Together, these findings reveal a direct molecular link between synonymous codon choice and the control of gene expression in human cells," said co-corresponding author Masanori Yoshinaga.

## Why This Discovery Could Change Everything We Know About Gene Regulation

The implications of this research stretch well beyond basic genetics. By demonstrating that codon selection directly influences whether a gene gets expressed or silenced, scientists have fundamentally expanded the definition of gene regulation. The DHX29-driven pathway may play meaningful roles in critical biological processes including cell differentiation, maintaining internal cellular balance, and even the onset and progression of cancer.

The research team intends to push further, investigating how DHX29 influences gene behavior across both healthy and diseased biological states.

"We have long been fascinated by how cells interpret the hidden layer of information embedded within the genetic code, so discovering the molecular factor that allows human cells to read and respond to this hidden code has been particularly rewarding," said team leader Osamu Takeuchi.

## A New Chapter in Our Understanding of the Genome

What was once considered biological noise — the apparent redundancy of synonymous codons — has turned out to be a sophisticated signaling system with its own rules and regulators. The discovery of DHX29's role in reading this secondary layer of genetic information represents a significant leap forward in molecular biology, offering fresh avenues for research into disease, therapeutic development, and our fundamental understanding of how life encodes and controls itself.

Scientists discover a secret second code in human DNA controlled by protein DHX29, revealing a new layer of gene regulation with major health implications.

## NASA's Artemis II Mission Makes History Near the Moon

NASA's Artemis II mission has reached a series of remarkable achievements during its historic journey around the Moon. The crew successfully completed a lunar flyby, shattered a record previously set during the Apollo era, and experienced a breathtaking eclipse from deep space — all before preparing for their anticipated return to Earth.

### A Landmark Lunar Flyby

As the Artemis II spacecraft arced around the Moon, the crew became the first astronauts in decades to travel this close to the lunar surface. The mission's trajectory allowed the team to observe the Moon up close, capturing a perspective that very few human beings have ever witnessed firsthand. This flyby represented one of the most significant moments in human spaceflight since the final Apollo missions of the early 1970s.

### Breaking an Apollo-Era Record

Among the mission's most celebrated accomplishments was surpassing a record that had stood since the Apollo program. While specific details of the record continue to generate excitement within the scientific community, the achievement underscores just how far NASA's new generation of lunar exploration has come — and signals the ambition driving the broader Artemis program forward.

### Witnessing an Eclipse from Space

Adding to the mission's extraordinary list of experiences, the Artemis II crew also had the rare opportunity to observe an eclipse while orbiting near the Moon. Witnessing such a celestial event from that vantage point is an experience shared by only a handful of humans in history, making this moment a deeply personal highlight for the astronauts aboard.

### Splashdown Expected on Friday

With its major milestones completed, the Artemis II spacecraft was on course to conclude its mission with a splashdown on Earth on Friday. The safe return of the crew would mark the successful conclusion of one of NASA's most ambitious human spaceflight missions in recent memory, paving the way for future lunar exploration and, eventually, crewed missions beyond the Moon.

## Scientists Decode Monkey DNA in Conservation Breakthrough

Researchers in the United Kingdom have accomplished what they are calling a global first — successfully mapping the complete genetic code of a Barbary macaque, a rare and endangered primate species. The historic achievement centers on a monkey named Crinkle, a resident of Trentham Monkey Forest in Stoke-on-Trent, Staffordshire, and experts believe it could fundamentally transform how conservationists protect vulnerable species worldwide.

## Who Is Crinkle and Why Does Her DNA Matter?

Crinkle is no ordinary monkey. As the first Barbary macaque ever to have her entire genome sequenced, she has become an unlikely hero in the battle against wildlife extinction. Until this breakthrough, scientists lacked a complete genetic reference for her species — a gap that severely limited their ability to monitor wild populations, assess genetic diversity, or trace the origins of animals caught up in illegal trafficking networks.

Matt Lovatt, Park Director at Trentham Monkey Forest, described the significance of the achievement in personal terms. "Knowing that her DNA could help protect Barbary macaques from poaching and illegal trade is something truly special," he said. "Crinkle represents not just our forest, but a species facing real threats in the wild."

## A Master Key for Conservation Science

Scientists involved in the project have described the newly decoded genome as a "master key" — one that opens previously locked doors in conservation research. Using this genetic blueprint, researchers have already traced Crinkle's ancestry to wild populations living near Ifrane National Park and Khenifra National Park in Morocco, two of the most critical remaining strongholds for the species.

This ability to pinpoint geographic origins is particularly significant in the fight against wildlife crime. When trafficked animals are seized by authorities, identifying where they were originally taken from has historically been extremely difficult. With a complete genetic reference now in place, scientists can cross-reference DNA samples and potentially determine the exact wild populations from which stolen animals were removed.

"If this kind of science can help identify where trafficked animals have been taken from, it becomes a powerful tool in the fight against wildlife crime," Lovatt added. "Ultimately, it gives us a better chance of protecting these incredible monkeys in the wild."

## A Species Under Serious Threat

The urgency behind this research is underscored by the precarious state of Barbary macaque populations. Dr. Patrick Tkaczynski of Liverpool John Moores University, one of the researchers involved in the project, noted that the species once roamed freely across much of the Mediterranean region. Today, however, surviving populations are confined to a handful of isolated pockets scattered across North Africa and the British Overseas Territory of Gibraltar.

Habitat destruction, human encroachment, and the illegal pet trade have all contributed to a dramatic decline in numbers, pushing the species toward endangered status. Without intervention — both on the ground and at the genetic science level — their future remains uncertain.

## Changing Conservation Forever

Researchers are optimistic that genome sequencing of this kind will set a precedent for how the scientific community approaches the protection of endangered species going forward. A complete genetic reference allows experts to monitor inbreeding, assess population health, and design more effective breeding and reintroduction programs.

"We're incredibly proud that a Barbary macaque from Trentham Monkey Forest is at the heart of such a groundbreaking scientific achievement," said Lovatt. The team believes the methodology pioneered through Crinkle's sequencing could be replicated for other at-risk species, potentially amplifying its conservation impact far beyond a single monkey in Staffordshire.

For Crinkle herself, life at Monkey Forest continues as usual — but her contribution to science may well echo through generations of Barbary macaques yet to come.

Scientists map the full genome of a Barbary macaque for the first time, creating a powerful new tool to fight poaching and protect an endangered species.

## NASA's Artemis II Mission Makes History Around the Moon

NASA's Artemis II mission has achieved a series of extraordinary milestones, with its crew successfully completing a lunar flyby that captured the attention of space enthusiasts worldwide. As the astronauts looped around the Moon, they etched their names into the history books in more ways than one — and the spacecraft is now on course to splash down on Earth on Friday.

## A Record-Breaking Journey

Among the most remarkable achievements of the mission was the breaking of a long-standing Apollo-era record. The Artemis II crew surpassed a benchmark set during the iconic Apollo program, marking a significant leap forward in human spaceflight history. This milestone underscores NASA's commitment to pushing the boundaries of exploration and building on the legacy of its predecessors.

## Witnessing a Rare Eclipse from Space

Adding to the mission's already impressive list of accomplishments, the crew was treated to a breathtaking and rare eclipse while in the vicinity of the Moon. Observing such a celestial event from the vantage point of deep space offered the astronauts a perspective that very few humans have ever experienced — a powerful reminder of the awe-inspiring nature of space exploration.

## Lunar Flyby and Return to Earth

The successful lunar flyby represented a critical phase of the Artemis II mission, serving as a vital test of the systems and procedures that will eventually support a crewed lunar landing. With the flyby now complete, all eyes are on the final leg of the journey as the crew prepares for reentry and splashdown. NASA expects the spacecraft to safely return to Earth on Friday, wrapping up a mission that has already proven to be a defining chapter in modern space exploration.

## What This Means for the Future of Space Exploration

Artemis II's success signals a new era of human spaceflight. As NASA continues to build momentum with the Artemis program, these milestones bring humanity one step closer to a sustained presence on and around the Moon — and ultimately, deeper into the solar system.

## A Tribute Written in the Stars

Space exploration has always carried a deeply human dimension, but the crew of NASA's Artemis II mission recently demonstrated just how personal that connection can be. During the mission, the astronauts proposed naming a crater on the Moon after Commander Reid Wiseman's late wife — a heartfelt act of remembrance that has resonated with people around the world.

## The Story Behind the Name

Astronaut Jeremy Hansen, speaking with NASA scientist Kelsey Young during the Artemis II mission, expressed the crew's desire to name several lunar craters that were visible to them — both with the naked eye and through long-range lenses.

Among those craters, a distinctive bright feature near the Moon's surface caught their attention. The crew put forward the name **"Carroll"** in honour of Carroll Taylor Wiseman, the commander's beloved wife, who lost her battle with cancer in 2020 at just 46 years old.

### A Loss That Shaped a Mission

Reid Wiseman's wife passed away five years before the Artemis II mission launched, yet her memory clearly travels with the crew. By proposing to etch her name onto the surface of the Moon, the astronauts transformed a scientific milestone into an enduring personal tribute.

## The Significance of the Gesture

Naming celestial features after individuals is a long-standing tradition in space exploration, typically reserved for scientists, explorers, and pioneers. In this case, the crew's proposal elevates a deeply private grief into something universal — a reminder that behind every mission are human beings carrying their own stories, sorrows, and love.

The name "Carroll" on the lunar surface would serve as a permanent memorial, visible from Earth and lasting far beyond any human lifetime.

## About the Artemis II Mission

Artemis II represents NASA's first crewed mission under the broader Artemis programme, which aims to return humans to the Moon. The crew, which includes Commander Reid Wiseman and astronaut Jeremy Hansen among others, has been training since 2023 at the Johnson Space Center in Texas. The mission marks a historic step forward in deep space exploration and lays the groundwork for future lunar landings.

The Artemis II crew proposed naming a lunar crater 'Carroll' in tribute to Commander Reid Wiseman's wife, who died of cancer in 2020 at age 46.

## A Human Eye Where No Camera Has Gone Before

For the first time in more than half a century, human beings are journeying to the moon — and what they're seeing cannot be replicated by any orbiting satellite. The four-person crew aboard NASA's Artemis II mission is offering scientists something no robotic probe ever could: real-time, nuanced human observation of Earth's nearest celestial neighbor.

Launched aboard the Orion space capsule atop a Space Launch System rocket from Kennedy Space Center, the mission has already shattered records. On Monday, at 1:57 p.m., the crew surpassed the Apollo 13 distance record of 248,655 miles, making Artemis II the farthest any humans have ever traveled into deep space.

## The Lunar Flyby: Seven Hours of Unprecedented Views

The mission's centerpiece is a roughly seven-hour lunar flyby during which astronauts Reid Wiseman, Victor Glover, and Christina Koch — all NASA — along with Canadian Space Agency astronaut Jeremy Hansen, will peer out the windows of Orion and relay live observations to scientists on the ground.

The crew woke Monday morning just 18,830 miles from the moon's surface, serenaded by "Good Morning" from Mandisa and TobyMac, before beginning their historic approach. During the flyby, they will pass over the former landing sites of Apollo 12 and 14, and catch a rare glimpse of the lunar south pole — a region NASA is targeting for crewed landings as early as 2028.

The astronauts will also witness something extraordinarily rare: a solar eclipse viewed in reverse, watching the sun vanish behind the moon from the opposite perspective that observers on Earth experience.

## Why Human Eyes Outperform Satellites

NASA does have extensive photographic coverage of the moon through instruments like the Lunar Reconnaissance Orbiter. So why does it matter that humans are up there looking?

Kelsey Young, Artemis II's lunar science lead, answered that question directly during pre-flyby press conferences. The human eye, she explained, is remarkably capable of detecting subtle color variations and surface textures — especially when paired with a trained scientific mind.

"The human eye, especially when it's connected to a well-trained brain — which I assure you these four people have — is capable of making nuanced color observations in literally the blink of an eye," Young said.

### The Sandbox Analogy

To illustrate the scientific value of different illumination angles, Young used a simple but powerful analogy. Imagine a sandbox at the beach — the sand isn't uniform. It has texture, varying grain sizes, and subtle color differences.

Now shine a flashlight directly from above: you'll see color variations and surface reflectivity clearly. Shift that same light to the side, and you lose the color nuance — but gain a sharp sense of topography and physical structure.

The Artemis II crew will experience both scenarios in real time. As the spacecraft moves around the moon, the angle of sunlight hitting the lunar surface will shift dramatically. This means the astronauts can observe the same locations under multiple illumination conditions — something no fixed-orbit satellite can replicate.

"We understand what the moon is made of. We understand the topography," Young said. "But we don't know what the crew are going to see in these specific illumination conditions from a scientific perspective. And that's exciting."

## Ten Science Objectives and 35 Geological Features

NASA has outlined ten distinct science objectives for this flyby. Among the most significant is documenting color variations across the lunar surface. Scientists have identified approximately 35 geological features for the crew to observe and describe throughout the approach, with live commentary expected several times per hour.

At closest approach, the far side of the moon — largely unseen by human eyes throughout history — will be approximately 21% illuminated, offering a unique viewing window into one of the most mysterious regions in our solar system.

Mission Commander Wiseman has already been delivering vivid real-time observations. In a post shared by NASA's Solar System account on X in the early hours of Sunday morning, he described looking at Tycho Crater:

*"You know I'm not one for hyperbole, but it's the only thing I can come up with. Just seeing Tycho — there are mountains to the north, you can see Copernicus, Reiner Gamma. It's just everything from the training but in three dimensions and absolutely unbelievable. This is incredible."*

Mission Control's reply was understated and perfect: *"Copy, moon joy."*

## A Higher Altitude, a Broader Perspective

While Apollo missions flew much closer — and several actually landed on the lunar surface — Orion's closest approach during Artemis II will be approximately 4,070 miles from the moon. Far from being a limitation, this altitude is scientifically strategic.

The greater distance allows the crew to view the moon as a complete disc, assessing surface features at a broader scale than Apollo-era astronauts ever could. Just as Apollo geologists trained crews to spot specific rock formations at close range, Artemis II astronauts are being asked to observe large-scale patterns — color gradients, reflectivity zones, and geological transitions — that only become visible when you step back far enough to see the whole picture.

## Thousands of Photos Expected

The Orion spacecraft is equipped with two Nikon D5 cameras and one Nikon Z9. Young anticipates the mission will produce thousands of images during the flyby, with NASA planning to release photos to the public as quickly as possible following the approach.

"The data we will get back will inspire the next generation of scientists and explorers," Young said. "But it will also bring the moon closer and unite all of us."

For a generation accustomed to seeing the moon through a telescope or a screen, Artemis II offers something different — and deeply human. It's the reminder that sometimes, the most sophisticated instrument we have is simply a pair of well-trained eyes.

## Scientists Achieve Remarkable Light-Trapping Feat at Nanoscale

A team of researchers has accomplished something that pushes the boundaries of modern physics — trapping infrared light inside a structure more than 1,000 times thinner than a single human hair. The layer measures just 40 nanometers thick, yet it successfully confines and intensifies light in ways that were previously considered out of reach. The findings, published in the journal *ACS Nano*, could fundamentally reshape the future of photonic technology.

The research was led by scientists from the Faculty of Physics at the University of Warsaw, in collaboration with teams from the Łódź University of Technology, Warsaw University of Technology, and the Polish Academy of Sciences.

## Why Controlling Light at Tiny Scales Matters

As conventional electronics approach their physical limits, photonics — the science of using light to carry information — has emerged as a promising alternative. Unlike electrons, photons travel faster and carry no mass, meaning devices built around light have the potential to be both smaller and significantly more powerful.

However, light's wave nature creates a fundamental challenge. Every wavelength of light has a natural size limit that dictates how small a controlling structure can be. Visible light spans several hundred nanometers, while infrared light stretches to a micrometer or beyond. The central question researchers have long wrestled with is whether light can truly be controlled within structures smaller than its own wavelength.

This new study answers that question with a definitive yes.

## The Key: A Special Material With Extraordinary Properties

The breakthrough hinges on a cleverly engineered structure called a **subwavelength grating**, built from a material known as **molybdenum diselenide (MoSe₂)**. The grating consists of tightly spaced parallel strips that interact with light in a manner similar to a prism. When these strips are packed closer together than the wavelength of the incoming light, the grating functions almost like a perfect mirror — while simultaneously locking light into an exceptionally small space.

Previous subwavelength gratings made from materials such as silicon or gallium compounds required thicknesses of several hundred nanometers to work properly. Shrinking them further caused their light-confining ability to break down entirely.

The game-changer here is MoSe₂'s unusually high **refractive index** — a measure of how much a material slows light down. For context:

- **Glass** slows light by approximately 1.5 times
- **Silicon and gallium arsenide** slow it by around 3.5 times
- **Molybdenum diselenide** slows light by roughly **4.5 times**

This exceptional light-slowing capability allows the structure to shrink to just 40 nanometers while still performing its light-trapping role with impressive efficiency.

## Turning Infrared Into Visible Blue Light

MoSe₂ offers more than just a high refractive index. Like graphene, it forms naturally layered structures — but unlike graphene, it behaves as a semiconductor. It also exhibits **nonlinear optical properties**, including a phenomenon called **third harmonic generation**.

In this process, three infrared photons merge into a single photon with a higher frequency, effectively converting invisible infrared light into visible **blue light**. Because the subwavelength grating concentrates infrared light so intensely, this conversion process becomes dramatically more efficient. According to the research team, the effect is more than **1,500 times stronger** than what is observed in a flat layer of the same material.

## Scaling Up: From Lab Curiosity to Real-World Application

One of the most significant hurdles in working with MoSe₂ has historically been production. Earlier methods relied on **exfoliation** — essentially peeling thin layers off a crystal using adhesive tape. While this technique works in a laboratory setting, it produces inconsistent results and is limited to areas of roughly ten square micrometers — far too small for practical devices.

To solve this, the team turned to **molecular beam epitaxy (MBE)**, a well-established semiconductor manufacturing technique. This method enabled them to grow large, uniform MoSe₂ films across areas spanning several square inches, all while maintaining a consistent thickness of just 40 nanometers.

To appreciate how extreme this is: the thickness-to-size ratio of this film is approximately **one to one million** — compared to a standard A4 sheet of paper, which has a ratio closer to 1:2,000.

Because MBE is a scalable production method, the path toward integrating this material into **photonic integrated circuits** and other real-world applications is now far more achievable.

## What This Means for the Future of Photonics

This research challenges the long-held assumption that photonic structures need to be thick to manipulate light effectively. Extremely thin layers can now perform the same functions — and in certain respects, outperform their bulkier predecessors.

The implications stretch across multiple industries. Smaller, faster photonic devices could revolutionize **telecommunications, computing, sensing technologies**, and beyond. As researchers continue refining this approach, the era of ultra-compact, light-based technology draws significantly closer.

*The research received funding from Poland's National Science Centre, the European Union's ERC-ADVANCED grant program, the Foundation for Polish Science, and the University of Warsaw's Excellence Initiative.*

Researchers trapped infrared light in a 40-nanometer layer using molybdenum diselenide, boosting light conversion 1,500x and advancing photonic tech.

## A Small Fish With an Extraordinary Talent

Deep within the Democratic Republic of Congo, researchers have made a discovery that is rewriting what we thought we knew about the physical limits of fish. A species native to the region has been observed doing something that seems almost impossible — scaling waterfalls that rise as high as 50 feet above the ground.

This is not a gentle slope or a modest stream bank. These are powerful, churning waterfalls, and yet this fish navigates them with a level of agility and determination that has left scientists genuinely astonished.

## What the Research Reveals

A new study focused on both the behavior and the anatomy of this remarkable species sheds light on how such an athletic feat is even possible. Researchers conducted detailed observations and physical examinations to understand what combination of biological traits allows this fish to do what most creatures — let alone aquatic ones — simply cannot.

The findings suggest that the fish possesses specialized anatomical features that work in concert with distinct behavioral strategies. Together, these traits allow it to grip slick rock surfaces, resist powerful currents, and propel itself upward in a controlled and deliberate manner.

### Body Built for the Climb

Unlike the vast majority of fish species, which are entirely dependent on open water for movement, this species appears to have evolved structures that make surface contact not only possible but effective. Its physical build gives it the mechanical advantage needed to shimmy upward against gravity and rushing water simultaneously — a dual challenge that would defeat virtually any other aquatic creature.

### Behavior That Matches the Body

Anatomy alone does not tell the whole story. The research also highlights that the fish demonstrates purposeful, repeatable climbing behavior. This is not accidental or random movement. The fish actively seeks out and ascends waterfalls, suggesting that climbing serves an important ecological or biological purpose — possibly related to migration, feeding, or reproduction.

## Why This Discovery Matters

Findings like these expand our understanding of evolutionary biology and the surprising directions in which life can develop. The Congo River basin is one of the most biologically diverse aquatic environments on Earth, and discoveries emerging from it continue to challenge scientific assumptions.

This research is a powerful reminder that nature is still full of secrets waiting to be uncovered — sometimes in the most unexpected places, and in the most unexpected creatures.

New research from the Congo reveals a fish species capable of scaling 50-foot waterfalls using unique anatomy and remarkable climbing behavior.

## Artemis II Astronauts Offer Rare Glimpse Into the Moon's Hidden Face

For the first time in decades, human eyes are gazing upon one of the solar system's most elusive landscapes — and the astronauts witnessing it are struggling to find adequate words to describe the experience.

The four-person crew aboard NASA's Artemis II mission has entered the third day of their ambitious journey, navigating the Orion spacecraft around the far side of the Moon before making their return to Earth.

## A Crew of Pioneers

The mission brings together three NASA astronauts — Reid Wiseman, Victor Glover, and Christina Koch — alongside Canadian Space Agency astronaut Jeremy Hansen. Together, they represent a new generation of space explorers pushing the boundaries of human reach beyond low Earth orbit.

### Koch's Words Capture the Moment

Among the crew's reflections, astronaut Christina Koch offered perhaps the most evocative description of encountering the lunar far side.

"Something about you senses that is not the Moon that I'm used to seeing," Koch remarked, capturing the disorienting yet extraordinary experience of observing a face of the Moon invisible to those on Earth.

Her words echo the sentiments of a crew confronting something genuinely unprecedented in their personal experience — and in modern human spaceflight.

## Tracking the Journey

As of 23:00 BST on Saturday, NASA's live mission dashboard confirmed that the Orion spacecraft had traveled more than **180,000 miles (approximately 289,681 kilometers)** from Earth — a testament to the sheer scale of this interplanetary endeavor.

The mission is designed not only to carry its crew around the lunar far side but also to serve as a critical test flight ahead of future Artemis missions that aim to return humans to the lunar surface for the first time since the Apollo era.

## Why the Far Side Matters

The Moon's far side — often mistakenly called the "dark side" — never faces Earth due to a phenomenon known as tidal locking. As a result, it remains largely shrouded in mystery for most people, and direct human observation of it is extraordinarily rare.

Artemis II represents a pivotal step in NASA's broader strategy to establish a sustained human presence near and on the Moon, with long-term goals focused on eventual crewed missions to Mars.

As the Orion spacecraft continues its trajectory and the crew's reflections continue to pour in, the world watches with anticipation — reminded once again of humanity's enduring drive to explore the unknown.

NASA's Artemis II astronauts share their awe-inspiring first impressions of the Moon's far side as they complete day three of their historic lunar mission.

## Welsh Government Takes Over Ffos-y-Fran Mine Restoration Decision

The Welsh government has intervened to determine the outcome of a deeply contested restoration plan for the site of the UK's last and largest opencast coal mine, located near Merthyr Tydfil in South Wales.

The decision to "call in" the application means that Welsh ministers — rather than Merthyr Tydfil County Borough Council — will have the final say over how the former Ffos-y-Fran mine site is cleaned up and returned to its natural state.

## A Cheaper Plan That Has Sparked Outrage

At the center of the dispute is Merthyr South Wales Ltd (MSW), the company responsible for operating the mine. MSW has put forward a scaled-back restoration proposal that would cost significantly less than the original agreement, warning that it lacks sufficient funds to carry out the full cleanup that had previously been committed to.

Under the revised plan, MSW proposes to reduce the height of one coal tip while leaving two others entirely in place — a far cry from the original scheme, which required all tips to be used to fill the mine's main void, a cavity stretching 175 metres (574 feet) deep.

The three remaining coal tips collectively contain an estimated 37 million cubic metres of material excavated during the mine's operational years.

## Background: A Mine Built on Promises

Ffos-y-Fran was granted approval in 2005 and was officially designated a "land reclamation scheme" — a classification that required a portion of profits generated from coal sales to be reinvested in restoring the land to green hillside upon closure. Over its 15-year lifespan, the mine produced approximately 11 million tonnes of coal, accounting for 86% of the UK's total coal output before it ceased operations.

Estimates for completing the full restoration vary considerably, with figures ranging from £50 million to as high as £175 million. MSW's newly proposed budget of just £15 million falls dramatically short of even the most conservative projections, which place a proper restoration at between £75 million and £120 million.

The company's most recently filed accounts do show a provision of approximately £91.2 million set aside for restoration obligations. However, correspondence from the local council to MSW has raised concerns that the company now appears to be banking on a £15 million emergency fund — originally established as a joint safety net in the event of insolvency — to cover the bulk of the costs.

MSW's consultants acknowledged the concerns, stating that detailed financial costings are currently being prepared.

## Local Campaigners Welcome Government Intervention

Residents living near the former mine have long opposed both its operation and the prospect of an inadequate restoration. Chris and Alyson Austin, who have campaigned on the issue for years, expressed relief at the Welsh government's involvement.

"We are really, really pleased," said Alyson Austin. "We've always felt the local authority lacked the capacity or resources to deal with a complex and controversial plan of this nature."

Her husband Chris echoed the sentiment, arguing that the issue carries national significance and demands a broader perspective than local government can provide.

"This plan isn't like approving an extension on Mrs Jones' house — it's much wider. The local authority has been too close to this for too long and doesn't have the breadth of resources the Welsh government will have," he said.

## Safety Concerns and Accusations of Profit-Grabbing

Critics have raised serious alarm over the safety implications of leaving the coal tips in place. A geotechnical assessment commissioned by the council warned of a "significant risk of slope instability" at the Ffos-y-Fran site.

Daniel Therkelsen, campaigns manager at Coal Action Network, was blunt in his assessment of MSW's motives.

"What we're talking about here is a very dangerous landscape," he said. "They talk about erecting fences to discourage people from going near the cliff edge, swimming in the void, or riding dirt bikes on the slopes. We've seen at other under-restored opencast sites that these kinds of measures simply haven't worked."

Therkelsen accused the company of a deliberate "profit grab," arguing that the reduced restoration budget represents an attempt to walk away from its obligations while extracting maximum financial benefit from the area.

MSW pushed back against the safety characterisations, insisting that comparing its "purpose-built, engineered structures" to historically unstable coal tips was "incorrect and misleading."

## Political Pressure Mounts

The Welsh Conservatives have criticised the Labour-led Welsh government over the timing of its intervention, alleging that ministers acted "far too late on Ffos-y-Fran" and suggesting the move was politically motivated ahead of an upcoming election.

The Welsh government declined to elaborate on its decision, stating only that it would be "inappropriate to comment further at this time" while the process is ongoing.

The Welsh government has called in a controversial restoration plan for the UK's largest former opencast mine, taking the decision away from local authorities.

## Artemis II Astronauts Are Sending Back Stunning Images From Space

Just days into NASA's historic Artemis II mission — the first crewed lunar voyage in more than 50 years — the four-member crew has already produced a remarkable collection of photographs that are capturing the world's attention. From intimate cabin snapshots to awe-inspiring views of our home planet, these images tell the story of a journey unlike any other.

## Commander Reid Wiseman Leads the Photography Effort

Artemis II Commander Reid Wiseman has emerged as the mission's primary photographer, snapping a series of extraordinary images from the windows of the Orion spacecraft following the completion of the translunar injection burn on April 2, 2026.

Among the most striking of his shots is an image of Earth nearly eclipsing the Sun, with a vivid display of zodiacal light visible in the frame. This triangular glow — created when sunlight scatters off suspended dust particles — is particularly visible during eclipse events. Adding to the visual drama, both the northern and southern auroras appear in the same photograph, framing Earth at opposite corners of the image.

Wiseman also captured Earth's terminator line, the sharp boundary that divides the sunlit side of the planet from the darkened side shrouded in night — a geographical and atmospheric detail rarely seen so clearly from this vantage point.

## Scientists Are Guiding the Crew on What to Photograph

The photography isn't entirely spontaneous. According to Lakiesha Hawkins, the acting deputy associate administrator for NASA's Exploration Systems Development Mission Directorate, the Artemis II crew is actively collaborating with NASA's science team to identify the most valuable photographic opportunities as the mission progresses.

As the spacecraft moves into lunar orbit, scientists will direct the crew toward specific subjects and angles that could yield scientifically significant images. This partnership between astronauts and researchers ensures that the mission's visual documentation serves both public inspiration and scientific discovery.

## A Historic Mission Already Making Its Mark

The Artemis II mission is carrying Commander Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen on a 10-day journey around the Moon and back aboard the Orion spacecraft. The crew has already participated in a media downlink event, answering questions from reporters while in transit — a milestone moment that underscores the mission's blend of exploration and public engagement.

With the lunar flyby still ahead, the crew's photography portfolio is only expected to grow more spectacular in the days to come.
