Tying light in knots

A team of physicists from Bristol, Glasgow and Southampton universities have successfully created knots in optical vortices using holograms designed with knot theory. This new research demonstrates the physical application of an abstract branch of mathematics previously considered impossible to apply.

30,000-year-old teeth shed new light on human evolution

A 30,000-year-old child's teeth found in Portugal provide insight into the evolution of modern humans and their relationship with Neanderthals. The analysis reveals that early modern humans had a different dental anatomy compared to recent humans, with greater volumes of dentin and pulp but less enamel.

Active hearing process in mosquitoes

A mathematical model explains how male mosquitoes can hear the faintest beats of a female's wings while resisting loud noises. The model reveals that scolopidia located toward the tip of Johnston's organ contribute to mechanical amplification.

Greenland ice cap melting faster than ever

A new study confirms the Greenland ice sheet is losing mass at an accelerating rate, primarily driven by accelerated iceberg production and increased surface meltwater. The research suggests this trend is likely to continue in the near future, with significant implications for global sea level rise.

Controversial new climate change data

The study found that terrestrial ecosystems and oceans have a much greater capacity to absorb CO2 than previously thought, with the airborne fraction of CO2 remaining stable at 0.7% per decade since 1850. This challenges recent research suggesting a decrease in absorption capacity as CO2 emissions rise.

New predictions for sea level rise

Researchers at University of Bristol predict sea level rise will be between 7-82 cm by end of century, similar to IPCC projections. The new model uses fossil coral data and temperature records from ice-core measurements to achieve accurate predictions.

Composites for energy

Recent studies suggest tidal stream devices could supply up to 5% of the UK's electricity needs, offering a solution with minimal environmental impacts. Collaborative projects are developing more fatigue-resistant materials and improved design techniques for wind turbine blades and solar energy converters.

Scientists demonstrate all-fiber quantum logic

Researchers at the University of Bristol have successfully implemented a high-fidelity fibre controlled-NOT gate using single photons in optical fibres. This achievement paves the way for more sophisticated quantum networks with increased range and potential applications in computing, communication, and advanced measurement.

Quantum ghosts are helpful

Physicists at University of Bristol and Imperial College London develop new method using 'spooky action' to identify quantum black boxes, overcoming fundamental limitations. This breakthrough has significant implications for future quantum computing and information science.

Comet impact theory disproved

New research published today disproves the recent comet impact theory that triggered continent-wide wildfires in North America 12,900 years ago. The study found no evidence for large-scale fires across the continent but supports a link between global warming and increased wildfires globally.

Cooling the planet with crops

By selecting crop varieties with higher solar reflectivity, researchers estimate a global cooling of over 0.1°C, equivalent to 20% of the total global temperature increase since the Industrial Revolution. The study proposes issuing farmers with carbon credits for growing such crops.

Spookfish uses mirrors for eyes

The four-eyed spookfish uses mirrors to focus light in its eyes, producing bright and high-contrast images. This unique adaptation gives the fish an edge in the deep sea, where spotting brief flashes of bioluminescent light can mean the difference between eating and being eaten.

More food at lower cost

A new study published in Nature Cell Biology has discovered a way to increase the length of root hairs on plants, potentially improving crop yields. This method enables plants to take up minerals and water more efficiently, reducing fertiliser waste and promoting sustainable food production.

World's earliest nuclear family found

Researchers found evidence of a mother, father, and two sons aged 8-9 and 4-5 years buried face-to-face with arms interlinked. The graves also showed signs of violent raids and injuries, indicating a tragic event in prehistoric Central Europe.

Which way 'out of Africa'?

Researchers find fossil river channels in Libya with a distinctly volcanic signature, supporting the theory that monsoon rains fueled rivers to the Mediterranean. The discovery provides an alternative route for early human migrations out of sub-Saharan Africa.

Molecular evolution is echoed in bat ears

Researchers studied the Prestin gene in echolocating bats and fruit bats, finding similarities in distantly related species. This suggests that echolocation has evolved more than once in bats, defying conventional wisdom on evolutionary relationships.

Why is Greenland covered in ice?

Research suggests that changes in atmospheric carbon dioxide levels are the primary cause of Greenland's ice formation, contrary to competing theories. The study uses computer climate and ice-sheet models to show that a decline in CO2 levels led to the long-term growth of the Greenland ice sheet.

Was it a bird or was it a plane?

A new study of extinct reptiles called kuehneosaurs shows that these early flyers used extraordinary extensions of their ribs to form large gliding surfaces on the side of the body. The research, published in Palaeontology, found that one species was more suited to parachuting than flying.

Will our future brains be smaller?

Researchers from the University of Bristol found that mammals have two decision-making systems: a fast-but-inaccurate sub-cortical brain and a slow-but-accurate outer cortex. The study suggests that the older system may still be beneficial in modern situations, potentially preventing atrophy and smaller brains in future humans.

Atomic tug of war

Researchers found that under certain conditions, a molecule can jump forward instead of backward when collided with another atom. This 'tug-of-war' behavior is crucial for understanding chemical reactions and their mechanics.

Passports for penguins

Scientists at the University of Bristol developed an intelligent, visual surveillance system to track African penguins' population dynamics and social behavior. The 'Penguin Recognition Project' uses unique biometric identifiers to monitor large numbers of species cheaply and automatically.

A plane with wings of glass?

Researchers have found that the special atomic structures formed in glass when it cools are responsible for its non-crystalline state. This breakthrough could lead to the development of new materials like metallic glasses, which could be used in flexible products such as aircraft wings and engine parts.

Are you looking at me?

Researchers at the University of Bristol demonstrate that birds respond to subtle signals from humans, including eye-gaze direction, to avoid predators. This ability allows starlings to gain valuable feeding time before others join a competitive foraging patch.
