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 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 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 Anemonefish are better taxonomists than humans



Scientists reveal new lineages of giant sea anemones in Japan and their surprising associations with anemonefish.
Published New study discovers how altered protein folding drives multicellular evolution



Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution.
Published Evolutionary nature of animal friendships



Biologists present groundbreaking research shedding new light on the evolution of social bonds and cooperation among group-living animals.
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 The Malaria parasite generates genetic diversity using an evolutionary 'copy-paste' tactic



All modern Plasmodium falciparum, the deadliest malaria parasite in humans, are descendants of one initial infection and so are very closely related, with relatively limited genetic differences. A long-standing mystery in the field has revolved around a very few locations in the P. falciparum genome where there are 'spikes' of mutations -- far more than anywhere else. Researchers have identified two genes in which these unusual mutation spikes result from DNA being copied and pasted from one gene to another.
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 Early life adversity leaves long-term signatures in baboon DNA



Early experiences in an animal's life can have a significant impact on its capacity to thrive, even years or decades later, and DNA methylation may help record their effects. In a study of 256 wild baboons, researchers found that resource limitation during early life was associated with many differences in DNA methylation, a small chemical mark on the DNA sequence that can affect gene activity.
Published The world's most prolific CO2-fixing enzyme is slowly getting better



New research has found that rubisco -- the enzyme that fuels all life on Earth -- is not stuck in an evolutionary rut after all. The largest analysis of rubisco ever has found that it is improving all the time -- just very, very slowly. These insights could potentially open up new routes to strengthen food security.
Published Revealing the evolutionary origin of genomic imprinting



Some of our genes can be expressed or silenced depending on whether we inherited them from our mother or our father. The mechanism behind this phenomenon, known as genomic imprinting, is determined by DNA modifications during egg and sperm production.
Published Synthetic gene helps explain the mysteries of transcription across species



'Random DNA' is naturally active in the one-celled fungi yeast, while such DNA is turned off as its natural state in mammalian cells, despite their having a common ancestor a billion years ago and the same basic molecular machinery, a new study finds.
Published AI can speed design of health software



Artificial intelligence helped clinicians to accelerate the design of diabetes prevention software, a new study finds.
Published Tiny worms tolerate Chornobyl radiation



A new study finds that exposure to chronic radiation from Chornobyl has not damaged the genomes of microscopic worms living there today -- which doesn't mean that the region is safe, the scientists caution, but suggests that these worms are exceptionally resilient.
Published Modeling the origins of life: New evidence for an 'RNA World'



Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other functional RNA strands, while also allowing new variants of the molecule to emerge over time. These remarkable capabilities suggest the earliest forms of evolution may have occurred on a molecular scale in RNA, and also bring scientists one step closer to re-creating autonomous RNA-based life in the laboratory.
Published An evolutionary mystery 125 million years in the making



Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.
Published New dressing robot can 'mimic' the actions of care-workers



Scientists have developed a new robot that can 'mimic' the two-handed movements of care-workers as they dress an individual.
Published Unraveling the mystery of chiton visual systems



You'd probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if it's one of the species with eyes dotting its platemail shell.
Published Convergent evolution of algal CO2-fixing organelles



Researchers identified the proteins of a CO2-fixing organelle, namely, 'pyrenoid,' in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal groups, suggesting the independent evolution of pyrenoids in different algal groups.
