Published Who knew that coprophagy was so vital for birds' survival?



New research explains how eating feces (known as coprophagy) shapes wild birds' digestive tracts (gut biota), enabling them to absorb lost or deficient nutrients and adjust to seasonal variations in food sources.
Published Batteries for airborne electric vehicles that take off and land vertically



Researchers are taking cleaner transportation to the skies by creating and evaluating new batteries for airborne electric vehicles that take off and land vertically. Researchers are developing new energy-dense materials, learning how these materials degrade under extreme conditions, and developing battery control systems.
Published The surprising effect of presence hallucinations on social perception



Neuroscientists have devised a way to alter our social perception and monitor specific types of hallucinations, both in healthy individuals and patients with Parkinson's disease. The test, which is also available online, provides the medical community with a tool to monitor hallucination susceptibility.
Published Scientists propose new theory that explains sand ripples on Mars and on Earth



Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?
Published Cheetahs' unrivalled speed explained by their 'sweet spot' size, finds Imperial study



A new study has answered a long-held question about why medium-sized land animals like cheetahs tend to be fastest.
Published How do neural networks learn? A mathematical formula explains how they detect relevant patterns



Neural networks have been powering breakthroughs in artificial intelligence, including the large language models that are now being used in a wide range of applications, from finance, to human resources to healthcare. But these networks remain a black box whose inner workings engineers and scientists struggle to understand. Now, a team has given neural networks the equivalent of an X-ray to uncover how they actually learn.
Published Cicadas' unique urination unlocks new understanding of fluid dynamics



While most small insects and mammals urinate in droplets, cicadas urinate in jets. Researchers say the finding could be used to create better robots and small nozzles.
Published Robotic interface masters a soft touch



Researchers have developed a haptic device capable of reproducing the softness of various materials, from a marshmallow to a beating heart, overcoming a deceptively complex challenge that has previously eluded roboticists.
Published Peering into the tendrils of NGC 604 with NASA's Webb



The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA's James Webb Space Telescope.
Published Going top shelf with AI to better track hockey data



Researchers got a valuable assist from artificial intelligence (AI) tools to help capture and analyze data from professional hockey games faster and more accurately than ever before, with big implications for the business of sports.
Published Nasa’s Webb, Hubble telescopes affirm universe’s expansion rate, puzzle persists



When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the 'Hubble Tension,' is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe's evolution.
Published AI-generated food images look tastier than real ones



Researchers have announced an intriguing discovery -- consumers generally prefer AI-generated images of food over real food images, especially when they are unaware of their true nature.
Published Researchers develop artificial building blocks of life



For the first time, scientists have developed artificial nucleotides, the building blocks of DNA, with several additional properties in the laboratory.
Published CSI in space: Analyzing bloodstain patterns in microgravity



As more people seek to go where no man has gone before, researchers are exploring how forensic science can be adapted to extraterrestrial environments. A new study highlights the behavior of blood in microgravity and the unique challenges of bloodstain pattern analysis aboard spacecraft.
Published Interstellar signal linked to aliens was actually just a truck



Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
Published The role of machine learning and computer vision in Imageomics



A new field promises to usher in a new era of using machine learning and computer vision to tackle small and large-scale questions about the biology of organisms around the globe.
Published Method rapidly verifies that a robot will avoid collisions



A new safety-check technique can prove with 100 percent accuracy that a planned robot motion will not result in a collision. The method can generate a proof in seconds and does so in a way that can be easily verified by a human.
Published Earth's earliest forest revealed in Somerset fossils



The oldest fossilized forest known on Earth -- dating from 390 million years ago -- has been found in the high sandstone cliffs along the Devon and Somerset coast of South West England.
Published Baby quasars: Growing supermassive black holes



The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we understand the genesis of supermassive black holes.
Published Bee-2-Bee influencing: Bees master complex tasks through social interaction



Bumblebees successfully learned a two-step puzzle box task through social observation. This task was too complex for individual bees to learn on their own. Observing trained demonstrator bees performing the first unrewarded step was crucial for successful social learning. Individual bees failed to solve the puzzle without previous demonstration, despite extensive exposure.
