Published Skin behind the ears and between the toes can host a collection of unhealthy microbes



Scrubbing behind the ears and between the toes may help keep the skin in those regions healthy, new research suggests. The microbiome, or the collection of microbes living on and in the human body, are known to play a role in human health and the skin is no different. A new study has shown that the composition of the skin microbiome varies across dry, moist and oily regions of the skin.
Published Solving a sticky, life-threatening problem



Researchers have zeroed in on C. auris' uncanny ability to stick to everything from skin to catheters and made a startling discovery: it uses a protein similar to that used by barnacles and mollusks.
Published Polyps as pixels: Innovative technique maps biochemistry of coral reefs



Using an innovative new approach to sampling corals, researchers are now able to create maps of coral biochemistry that reveal with unprecedented detail the distribution of compounds that are integral to the healthy functioning of reefs.
Published Wild Asian elephants display unique puzzle solving skills



A new study has documented the abilities of individual wild Asian elephants to access food by solving puzzles that unlocked storage boxes. It is the first research study to show that individual wild elephants have different willingness and abilities to problem solve in order to get food.
Published Boo to a goose -- new animal behaviour tech aims to save wildlife



Facial recognition software used to study the social behavior of individual Greylag Geese in Europe will soon be used to monitor one of the rarest geese in the world, the Cape Barren Goose in South Australia. The technology was used to assess how each bird responds to images of themselves, other flock mates or partners and researchers say it could be used by other scientists or in citizen science apps around the world to monitor and record endangered wildlife or even to promote the welfare of animals in captivity.
Published Why are killer whales harassing and killing porpoises without eating them?



For decades, fish-eating killer whales in the Pacific Northwest have been observed harassing and even killing porpoises without consuming them —- a perplexing behavior that has long intrigued scientists.
Published Whales Around the World Play With Kelp Clumps



A new article has analyzed another understudied behavior in baleen (filter-feeding) whales such as humpback whales in different populations across the northern and southern hemispheres. They appeared to roll around and 'play' with clumps of kelp and seaweed at the water's surface. The research also emphasizes that the behavior was similar in different individuals, regardless of where in the world it occurred.
Published Sperm swimming is caused by the same patterns that are believed to dictate zebra stripes



Patterns of chemical interactions are thought to create patterns in nature such as stripes and spots. This new study shows that the mathematical basis of these patterns also governs how sperm tail moves.
Published Drug discovery on an unprecedented scale


Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers teamed up with industry and supercomputers to carry out one of the world's largest virtual drug screens.
Published Jellyfish, with no central brain, shown to learn from past experience



Even without a central brain, jellyfish can learn from past experiences like humans, mice, and flies, scientists report for the first time. They trained Caribbean box jellyfish (Tripedalia cystophora) to learn to spot and dodge obstacles. The study challenges previous notions that advanced learning requires a centralized brain and sheds light on the evolutionary roots of learning and memory.
Published Conversations with plants: Can we provide plants with advance warning of impending dangers?



Plant scientists have engineered a light-controlled gene expression system (optogenetics system) from a prokaryotic system into a eukaryotic system that is tailored for plants.
Published AI helps bring clarity to LASIK patients facing cataract surgery


Scientists develop computer models of patients' eyes to identify the ideal intraocular lenses and visual simulators for patients to experience how they will see with them.
Published This parasitic plant convinces hosts to grow into its own flesh--it's also an extreme example of genome shrinkage



Balanophora shed one third of its genes as it evolved into a streamlined parasitic plant -- an extreme degree of genome shrinkage even among parasites. Along the way this subtropical plant developed the ability to induce the host plant to grow into the parasite's own flesh -- forming chimeric organs that mix host and parasite tissues.
Published Dinosaur feathers reveal traces of ancient proteins



Palaeontologists have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather evolution.
Published Archaeologists discover world's oldest wooden structure



Half a million years ago, earlier than was previously thought possible, humans were building structures made of wood, according to new research.
Published Slow growth in crocodile ancestors pre-dated their semi-aquatic lifestyle



A groundbreaking study is reshaping our understanding of crocodile evolution by pinpointing the onset of slow growth rates to the Late Triassic period, much earlier than the previously assumed Early Jurassic timeline. The research highlights newly discovered fossil crocodile ancestors (known as crocodylomorphs) that exhibited slow growth rates, similar to modern-day crocodilians. Intriguingly, these early crocodylomorphs were not the lethargic, semi-aquatic creatures we are familiar with today; they were small, active, and fully terrestrial. The study also suggests that this slow-growth strategy was not a mere evolutionary quirk but a survival mechanism, as only the slow-growing crocodylomorphs managed to survive the End-Triassic mass extinction. This stands in stark contrast to the fast-growing dinosaurs of the same era, setting the stage for the divergent evolutionary paths that would later define their modern descendants.
Published A newly identified virus emerges from the deep



Marine virologists analyzed sediment from the Mariana Trench, the deepest place on Earth, and identified a new bacteriophage.
Published Spider silk is spun by silkworms for the first time, offering a green alternative to synthetic fibers


Scientists have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests. The study is the first to successfully produce full-length spider silk proteins using silkworms. The findings demonstrate a technique that could be used to manufacture an environmentally friendly alternative to synthetic commercial fibers such as nylon.
Published Prehistoric fish fills 100 million year gap in evolution of the skull



X-rays of an ancient jawless fish shows earliest-known example of internal cartilage skull, unlike that of any other known vertebrate.
Published Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction



A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.
