Medical Xpress / Pigs and grizzlies, not monkeys, hold clues to youthful human skin
The secret to youthful appearance and repairing scars may lie in a microscopic skin structure humans share with pigs and grizzly bears—but, surprisingly, not monkeys.
Medical Xpress / 4D-printed vascular stent deploys at body temperature, eliminating external heating
Next-generation vascular stents can make cardiovascular therapies minimally invasive and vascular treatments safe and less burdensome. In a new advancement, researchers from Japan and China have successfully proposed a novel ...
Phys.org / Stacking the genetic deck: How some plant hybrids beat the odds by erasing lethal genes
In the plant world, when two different species mate, their offspring often don't survive. The reason lies in their DNA: incompatible genes often mix in their offspring, triggering a fatal breakdown known as hybrid lethality ...
Phys.org / Tropical weather cycles linked to faster Arctic ice loss in autumn
When it comes to global warming and climate change, we often hear news stories about tipping points where Earth's systems shift into a new and dangerous state. One such may have been reached in the year 2000 that caused tropical ...
Medical Xpress / Pandemic disruptions to health care worsened cancer survival, study suggests
During the early years of the COVID-19 pandemic, experts worried that disruptions to cancer diagnosis and treatment would cost lives. A new study suggests they were right.
Phys.org / Reproduction in space, an environment hostile to human biology
As commercial spaceflight draws ever closer and time spent in space continues to extend, the question of reproductive health beyond the bounds of planet Earth is no longer theoretical but now "urgently practical," according ...
Phys.org / Lab study suggests longer waves fracture floating ice sheets at lower stress
When waves are moving across ice-covered seas, they can cause sheets of ice to bend and ultimately break. Understanding the processes underlying these wave-induced ice fractures and predicting when they will occur could help ...
Phys.org / Spider spinneret evolution: How a genome duplication event 438 million years ago set the stage
Scientists have uncovered a 400-million-year-old genetic secret that gave spiders the ability to produce silk and weave their webs. Spiders didn't begin their journey on Earth in the same way as they are known today. Arthropods ...
Phys.org / Supermassive black holes sit in 'eye of their own storms,' studies find
Gigantic black holes lurk at the center of virtually every galaxy, including ours, but we've lacked a precise picture of what impact they have on their surroundings. However, a University of Chicago-led group of scientists ...
Phys.org / How cities primed spotted lanternflies to thrive in the US
Spotted lanternflies are adapting to the pressures of city life such as heat, pollution, and pesticides, according to genomic analyses of the invasive insects in the US and their native China. The findings, published in the ...
Tech Xplore / Study identifies key elements that determine impact of AI on jobs
Research by academics at King's College London and the AI Objectives Institute has shed light on why what matters is not just how much of a job AI can do, but which parts. Dr. Bouke Klein Teeselink and Daniel Carey analyzed ...
Medical Xpress / 'Missing link' protein key to restoring disorganized blood vessels
Blood flows around the body through a complex network of vessels, which must constantly adapt to changing needs. The balance between growing new vessels and stabilizing existing vessels, so they aren't leaky, must be finely ...
