Medical Xpress / Exposure to bright evening light linked to higher risk of age-related eye disease
Every sunrise and sunset sends the body a signal, keeping the circadian clock running on a roughly 24-hour cycle. This clock evolved so organisms could adapt to Earth's daily rotation, syncing their biology to the pattern ...
Phys.org / The oldest evidence of mourning rituals reveals Paleolithic communities grieved like we do
Roughly 27,500 years ago, a 15-year-old boy was brutally mauled by a bear in Arene Candide in what is now Liguria, Italy. The attack tore through his jaw, neck and left shoulder. He was dying, but he was not alone in his ...
Phys.org / Two humpback whales set records swimming between Australia and Brazil
Scientists have spotted two humpback whales that made separate, record-breaking crossings between Australia and Brazil.
Phys.org / Tiny water droplets transmutate aniline into pyridine in ambient and catalyst-free conditions
Aniline can now be transformed into pyridine without adding any catalysts, oxidants or toxic reagents. In a recent study published in the Journal of the American Chemical Society, researchers achieved skeletal editing, involving ...
Medical Xpress / Fatal rabies case with no visible wound shows why bat contact alone should trigger immediate vaccination, experts say
Ontario's first fatal rabies case since 1967 provides critical guidance to help prevent deaths from rabies in future cases. The article was published in the Canadian Medical Association Journal.
Tech Xplore / Brain-inspired AI architecture could compute faster while using far less power
Spiking neural networks (SNNs) are artificial intelligence (AI) models inspired by how biological neurons communicate with each other. While biological neurons exchange information in the form of electrical impulses, SNNs ...
Phys.org / Swiss glaciers have exhausted their snow reserves
From June 29 onward, Switzerland's glaciers will have exhausted their snow reserves. Every liter of meltwater now causes them to lose mass—this is Glacier Loss Day. Between the extreme years of 2003 and 2022 alone, 200 square ...
Phys.org / Newly described Australian ballista spider builds a spring-loaded snare to catch a single ant species
An international team of researchers has discovered a remarkable new spider species in the rainforest of North Queensland that spins an ingenious and powerful spring-actuated snare to catch a single species of ant—one ant ...
Phys.org / The order of species loss alters how grasslands maintain stability, study finds
Grasslands account for roughly 40% of terrestrial ecosystems and are paramount to global food security. Wild grasslands provide food for livestock and habitat for pollinators and act as a carbon sink in the era of climate ...
Medical Xpress / Hope for spinal injuries as pigs walk again after experimental gel treatment for severed spinal cords
In humans and other mammals, spinal cord injuries can be devastating, leading to permanent loss of movement, sensation and bladder control. When severed axons (the long fibers that carry messages between nerve cells) cannot ...
Medical Xpress / Poor metabolic health can age the brain even in young people, finds new large-scale study
Two people of very different ages can have a similar level of biological aging in their brains. Such an occurrence is possible because aging and metabolic health follow two distinct pathways that influence brain health. While ...
Phys.org / Beetle-like borings in 70-million-year-old titanosaur fossils reshape Lo Hueco fossil story
Traces or perforations caused by living organisms after an animal's death can be found on various dinosaur bone remains. These perforations, known as bioerosion structures, provide information that helps us understand relationships ...
