Phys.org / Early snakes explored life underground, on land and at sea
Snakes are highly modified lizards, with more than 4,000 living species today. The origin of snakes has long been one of evolutionary biology's most debated questions. Their sparse fossil record has made it hard to pin down ...
Phys.org / Using salt to drive drug-carrying particles deeper into difficult-to-treat biofilms
Biofilms—bacterial communities encased in a sticky, polymer-rich matrix—can be difficult to treat because that matrix slows antibiotics and drug-carrying particles. With help from salt, though, Yale researchers have found ...
Phys.org / 'Flying focus' laser overcomes key limitation in plasma-based particle accelerators
In a new Nature Physics study, researchers accelerated electrons to more than twice the energy predicted by the traditional dephasing limit for laser-plasma accelerators operating over the same distance. This was made possible ...
Medical Xpress / High glucose thickens cancer cells' sugar shield, helping them evade immune attack
Like spies evading detection by mastering disguises, many cancer cells are adorned with a copious coat of sugar-derived molecules that throws the proverbial hounds of the immune system off the scent.
Medical Xpress / New study finds bacterial infections affect about 1 in 20 hospitalized adults with firearm injuries
A new study by researchers at the University of Maryland School of Medicine (UMSOM) found that bacterial infections develop in approximately 5% of adults hospitalized with firearm injuries, with most infections occurring ...
Phys.org / How dogs evolved differently across the globe to match human traits
We call them "man's best friend," and the evidence supports it. Dogs have been found buried alongside humans in graves dating back 14,000 years. They appear in ancient art from every continent, and they feature in the mythology, ...
Phys.org / Swarms of tiny robots remove microplastics from soil and water
Microplastics, which are plastic particles under 5 millimeters, are a major and growing threat in both soil and water. They damage soil fertility, disrupt nutrient cycling, harm aquatic and terrestrial life, and can move ...
Phys.org / Pulsed radiofrequency magnetic fields may disorient migratory birds, experiments suggest
Every year, millions of migratory birds travel between different geographical regions on Earth to find food, escape cold weather or reach safe environments to raise chicks. To determine which direction to fly, these birds ...
Medical Xpress / Low-fat vegan diet cuts dietary energy density by nearly a third, helping explain weight loss
A low-fat vegan diet lowers the energy density of the foods people eat by roughly 30%, allowing them to eat satisfying amounts of food while taking in fewer calories and losing weight—without deliberately restricting calories—according ...
Medical Xpress / Two-stage process helps metastatic cancer cells hide, then multiply in the lungs
Most cancer deaths are caused not by the initial tumor but by the spread of cancer cells to distant organs in the process called metastasis. Since it occurs at the cellular level, the earliest stages of metastasis are difficult ...
Medical Xpress / Molecular mapping reveals hidden cellular programs in heart transplant rejection
A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection.
Tech Xplore / AI framework rooted in cognitive science could complete tasks more efficiently
In recent years, computer scientists have developed a wide range of artificial intelligence (AI) models that can rapidly recognize patterns in data, generate content and solve other computational problems. Many of these AI ...
