Medical Xpress / Common midlife vascular risk factors may cut dementia-free life by up to 13 years
A new study, published in Neurology Open Access, shows an association between three common vascular risk factors and the amount of dementia-free time people experience after age 55. The study hints that dementia is not inevitable ...
Phys.org / Two-qubit entangling gate flags its own errors as detectable photon losses
Quantum errors are a normal part of quantum computing because fragile physical qubits (the tiny components storing data) can easily break down because of environmental noise, like heat, stray signals or microscopic vibrations. ...
Phys.org / Ant teams beat gravity-based puzzle solvers
Ants live in highly organized colonies and cooperate daily to tackle a wide range of problems. Their striking group behaviors have fascinated biologists for centuries and even inspired the development of various artificial ...
Phys.org / Gut cells may measure hunger by how watery their insides become
Researchers led by Sa Kan Yoo at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have discovered that the natural turnover of gut cells in fruit flies depends on how much food the flies get, rather than on ...
Phys.org / Nocturnal 'coffee frog' discovered in Costa Rica
A tiny greenish, nocturnal frog that thrives in coffee plantations has been discovered in Costa Rica's central Pacific region, where it also faces risks from agrochemicals used in farming.
Phys.org / Songbirds may have developed sharper senses to de-husk seeds
Songbirds, birds belonging to the Passeriformes order, are best known for their ability to produce complex musical sounds. Yet some songbird species also have another remarkable skill: They can easily remove the tough layer ...
Phys.org / Runaway supermassive black hole RBH-1 offers new way to reconstruct ancient merger
Black holes are fascinating regions in space where gravity is so strong that nothing, even light, can escape them. The largest known black holes, called supermassive black holes, contain millions to billions of times the ...
Phys.org / Simulations hint at a hidden population of companionless black holes
So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, ...
Medical Xpress / Study points to new target for treating aggressive brain cancer
Glioblastoma remains one of the deadliest cancers, with limited treatment advances and tumors that often resist radiation and chemotherapy. New research from The Ohio State University Comprehensive Cancer Center–Arthur G. ...
Phys.org / Australia has pledged to restore nature. But could we ever bring back lost ecosystems?
Nature is not doing well in Australia. Many unique mammals, birds and insects are struggling. Entire ecosystems are collapsing.
Phys.org / Venus's polygonal plains could point to a watery past
Venus may be overwhelmingly inhospitable today, but many planetary scientists believe that it wasn't always this way. Billions of years ago, some observational evidence suggested that our planetary neighbor may have looked ...
Medical Xpress / Rare bone disease often goes untreated while patients quietly live with chronic pain
Teeth and bones are among the hardest structures in the human body, but certain inherited conditions can rob them of that strength. One of them is hypophosphatasia (HPP), a rare, lifelong genetic bone disorder that disrupts ...
