Phys.org / Q&A: Why do telomeres shorten when a cell divides, and how does it affect human aging?
In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, but over time, the copying process degrades. After many cycles of making copies, the ends of the ...
Medical Xpress / Common blood pressure medication associated with poorer kidney outcomes in type 2 diabetes
New research presented at the 63rd ERA Congress suggests that a widely used class of blood pressure medications may be associated with poorer kidney outcomes in people with type 2 diabetes (T2D), even among patients already ...
Phys.org / Exploring the meanings of plants and hair, from Amazon pastures to suburban lawns and groomed bodies
Cultivated lawns, cleared cattle pastures and carefully groomed hair all reflect a shared cultural logic, according to a new book by UC Santa Barbara anthropology professor Jeffrey Hoelle.
Phys.org / Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks
Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel ...
Phys.org / A giant star may have destroyed itself in one of the universe's rarest explosions
Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in the universe, leaving ...
Medical Xpress / Habits form far faster than previously thought, research shows
From responding to the ping of your phone notification to reaching for a snack at the end of the day, many everyday behaviors begin as mindful choices and end up feeling almost automatic. Now a study from Johns Hopkins University, ...
Tech Xplore / AI system spots fake reviews by combining text, images and user behavior
Research published in the International Journal of Information and Communication Technology discusses the development of an artificial intelligence system that combines text, images and reviewer behavior to detect and trace ...
Phys.org / First deliberately injured Langobard woman in skeletal record reshapes view of male-only violence
The Langobards are frequently depicted as fierce warrior-like people, with all known archaeological evidence of violence restricted to men. However, nearly 1,400 years ago, a Langobard woman took two severe injuries to the ...
Phys.org / Overarming America: Game theory explores how fear and social pressure drive gun purchases
A Dartmouth College study is the first to map the interplay of personal choice and social networks that has led to the United States being one of the world's most heavily armed countries, with 120 firearms for every 100 people. ...
Phys.org / Bison restoration efforts and grazing rights hinge on one question: Are bison wildlife?
Bison are political animals. A federal decision to revoke grazing leases for bison on public lands on the rolling plains of eastern Montana is the latest manifestation of long-standing contention. The largest land animal ...
Phys.org / Brightness 'gap' in ancient star cluster reveals missing red dwarfs
Scientists from the Space Telescope Science Institute (STScI) in Baltimore, Maryland, sought to study one stellar subject and ended up finding something even more exciting. The team's results published today in Astronomy ...
Phys.org / Nanomagnets control diamond qubits, pointing to more scalable quantum hardware
Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only if scientists can build and scale the hardware needed to run the machines. New research from Virginia ...
