Enzyme discovered in the gut could lead to new disease biomarker
Enzymes used by bacteria to break down mucus in the gut could provide a useful biomarker for intestinal diseases, according to new research published. Researchers at the University of Birmingham and Newcastle University have successfully identified and characterised one of the key enzymes involved in this process.

Using air to amplify light
In a promising breakthrough for the future of communications, EPFL researchers have developed a technology that can amplify light in the latest hollow-core optical fibers. "The idea had been going around my head for about 15 years, but I never had the time or the resources to do anything about it." But now Luc Thévenaz, the head of the Fiber Optics Group in EPFL's School of Engineering, has finally made it happen: his lab has developed a technology to amplify light inside the latest hollow-core optical fibers.

A wound dressing that kills bacteria
A wound dressing that kills bacteria
In order to combat bacterial wound infections, Empa researchers have developed cellulose membranes equipped with antimicrobial peptides. Initial results show: The skin-friendly membranes made of plant-based materials kill bacteria very efficiently. If germs invade a wound, they can trigger a long-lasting infection that may fail to heal or even spread throughout the body, leading to life-threatening blood poisoning (sepsis).

Impact of Covid-19 has created stark discrepancies in students’ experiences of taking A Levels says new study
Research from the University of Birmingham and University of Nottingham has indicated some stark discrepancies in students' experiences of taking A-levels this year. The researchers, Professor Kalwant Bhopal at the University of Birmingham and Dr Martin Myers at the University of Nottingham, conducted over 500 survey questionnaires (to date) over a four month period, between April and July with students whose A levels were cancelled due to the pandemic.

Some dinosaurs could fly before they were birds
Updated evolutionary tree and biomechanical estimates of feathered dinosaurs and early birds show powered flight may have evolved in these animals at least three different times New research using the most comprehensive study of feathered dinosaurs and early birds has revised the evolutionary relationships of dinosaurs at the origin of birds.

Dwarf Planet Ceres: Evidence of Active Cryovolcanism
Dwarf Planet Ceres: Evidence of Active Cryovolcanism
Until a million years ago, dwarf planet Ceres, the largest body in the asteroid belt, was the scene of cryovolcanic eruptions: below the Occator Crater, subsurface brine pushed upward; the water evaporated, leaving behind bright, salty deposits. This process is probably still ongoing. A team of researchers led by the Max Planck Institute for Solar System Research (MPS) in Germany comes to these conclusions after evaluating high-resolution camera images of Ceres from the final phase of NASA's Dawn mission.

A quarter of puppies are taken from their mothers prematurely
One in four people acquired their puppies before the advised age of eight weeks old, according to new findings from Dogs Trust's pioneering dog welfare study 'Generation Pup'. The 'cohort' study follows a generation of puppies over the course of their lifetime, to investigate how factors such as environment, social interaction, diet and exercise can impact their development in later life.

Coronavirus-related children’s diseases linked to blood cell changes - study
A newly-described disease occurring in children and linked to COVID-19 has significant changes in white blood cells - a discovery that may allow doctors to better assess their young patients' condition and predict their resistance to current treatments, a new study reveals. Paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 infection (PIMS-TS) is a new disease which shares some features with Kawasaki disease, as well as toxic shock syndrome.

Metallic blue fruits use fat to produce colour and signal a treat for birds
Metallic blue fruits use fat to produce colour and signal a treat for birds
Researchers have found a common plant owes the dazzling blue colour of its fruit to fat in its cellular structure, the first time this type of colour production has been observed in nature. The plant, Viburnum tinus , is an evergreen shrub widespread across the UK and the rest of Europe, which produces metallic blue fruits that are rich in fat.

Satellite Record Gives Unprecedented View of Antarctic Ice Shelf Melt Pattern over 25 Years
New estimates of ice shelf melting around Antarctica since the 1990s show where and when ice has been lost and where meltwater entered the Southern Ocean A science team led by researchers at Scripps Institution of Oceanography at UC San Diego has created a detailed history of mass loss from Antarctica's floating ice shelves.

Indigenous Property Rights Protect the Amazon Rainforest
One way to cut back on deforestation in the Amazon rainforest - and help in the global fight against climate change - is to grant more of Brazil's indigenous communities full property rights to tribal lands. This policy focus is suggested by a new University California of San Diego study published in the Proceedings of the National Academy of Sciences.

Deep learning and metamaterials make the invisible visible
Deep learning and metamaterials make the invisible visible
By combining purpose-built materials and neural networks, researchers at EPFL have shown that sound can be used in high-resolution imagery. Imaging allows us to depict an object through far-field analysis of the lightand sound-waves that it transmits or radiates. The shorter the wave, the higher the image's resolution.

Fireflies shed light on the function of mitochondria
The mitochondria provide energy for our cells, yet their role in many diseases is still poorly understood. Thanks to a bioluminescent molecule, scientists at EPFL can observe them at work in living mammals Tiny factories float inside our cells and provide them with almost all the energy they need: the mitochondria.

A highly light-absorbent and tunable material
A highly light-absorbent and tunable material
By layering different two-dimensional materials, physicists at the University of Basel have created a novel structure with the ability to absorb almost all light of a selected wavelength. The achievement relies on a double layer of molybdenum disulfide. The new structure's particular properties make it a candidate for applications in optical components or as a source of individual photons, which play a key role in quantum research.

"Simulation microscope" examines transistors of the future
Since the discovery of graphene, two-dimensional materials have been the focus of materials research. Among other things, they could be used to build tiny, high-performance transistors. Researchers at ETH Zurich and EPF Lausanne have now simulated and evaluated one hundred possible materials for this purpose and discovered 13 promising candidates.

Dwarf planet Ceres has reservoirs of salty water
The dwarf planet Ceres, about 940 kilometers (585 miles) in diameter, is the largest body in the main asteroid belt. NASA's Dawn spacecraft mapped the planet and found evidence - a low-density region of the crust (blue) - of an underground brine reservoir. A crater named Occator is to the left of the blue area This composite image shows gravity anomalies (red is high, blue is low) on the right side and Ceres' real colors on the left.

Simulating crash into asteroid reveals its heavy metal psyche
A new study of the biggest Main Belt asteroid, Psyche, finds it might be the remnant of a planet that never fully formed Psyche is an interesting body to study because it is likely the remnant of a planetary core that was disrupted during the accretion stage, and we can learn a lot about planetary formation from Psyche if it is indeed primarily metallic.

How airplanes counteract St. Elmo’s Fire during thunderstorms
On the ground, windy conditions strengthen these electrical flashes, but new experiments tell a different story for flying objects. At the height of a thunderstorm, the tips of cell towers, telephone poles, and other tall, electrically conductive structures can spontaneously emit a flash of blue light.
