Think of them as the Energizer Bunnies of the heart, tiny natural batteries that keep this vital organ beating 100,000 times a day as it pumps 2,000 gallons of blood throughout the human body. But when those batteries—heart muscle cells called cardiomyocytes—short circuit and die, the damage can be devastating. The damage to the heart muscle is [...]
Human fingers and toes don't grow outward as you might expect. Instead, our dexterous digits are 'sculpted' within a larger foundational bud. Now the first human cell atlas of early limb development has at last revealed in exquisite detail exactly how that happens. Prior to this, our understanding of vertebrate limb development has been largely based [...]
Polymer solar cells, known for their light weight and flexibility, are ideal for wearable devices. Yet, their broader use is hindered by the toxic halogenated solvents required in their production. These solvents pose environmental and health risks, limiting the appeal of these solar cells. Alternative solvents, which are less toxic, unfortunately, lack the same [...]
A University of Michigan-led study based on a review of genetic and health information from more than 276,000 people finds strong support for a decades-old evolutionary theory that sought to explain aging and senescence. In 1957, evolutionary biologist George Williams proposed that genetic mutations that contribute to aging could be favored by natural selection [...]
On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But at the nanoscale of today's most cutting-edge semiconductors, those phonons don't remove enough heat. That's why Purdue University researchers are focused on opening a new nanoscale lane on the heat transfer highway by using hybrid quasiparticles [...]
The European Union will seek to thrash out an agreement on sweeping rules to regulate artificial intelligence on Wednesday, following months of difficult negotiations in particular on how to monitor generative AI applications like ChatGPT. The EU is racing to approve the world's first comprehensive AI law after the issue took on greater urgency [...]
Scientists at the University of Illinois Urbana-Champaign have developed a portable, self-powered ultraviolet-C device called the Tribo-sanitizer that can inactivate two of the bacteria responsible for many foodborne illnesses and deaths. The Tribo-sanitizer's UVC lamp is powered using the triboelectric effect—electricity that is generated when two dissimilar materials come into contact. In tests, the [...]
A new study indicates that 3D retinal scans could revolutionize the early detection and monitoring of kidney disease, offering a non-invasive and efficient diagnostic tool. 3D eye scans can reveal vital clues about kidney health that could help to track the progression of disease, research suggests. The advance could revolutionize the monitoring of kidney [...]
Research carried out at Oxford's Nuffield Department of Clinical Neurosciences has led to the development of a new blood-based test to identify the pathology that triggers Parkinson's disease before the main symptoms occur. This could allow clinicians to screen for those individuals at high risk of developing the disease and facilitate the timely introduction [...]
Biochemists at Case Western Reserve are concentrating on the degradation of a key protein that drives cancer; represents a major shift in research. Biochemical researchers at Case Western Reserve University have discovered a a new function of a key protein that leads to cancer–a finding they believe could lead to more effective treatments for a range [...]
