Phys.org / Quantum entanglement offers route to higher-resolution optical astronomy
Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter-Jan Stas at Harvard ...
Medical Xpress / 1 in 3 Americans say sacrificed for health care costs
One in three Americans said they made some sacrifice last year—like skipping a meal or rationing medicine—to cover health care costs, according to a survey released Thursday.
Medical Xpress / Three-year study tracks early Parkinson's decline using wearables and patient reports
A new study in the Journal of Neurology offers critical longitudinal insights into how symptoms and functional impacts evolve for individuals with early Parkinson's disease (PD). Led by Jamie Adams, M.D. and Jennifer Mammen, ...
Phys.org / How changes on the Y chromosome may make species reproductively incompatible
When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males first, with hybrid males frequently failing to produce functional sperm even when hybrid females ...
Phys.org / Superconductivity controlled by a built-in light-confining cavity
For the first time, physicists have demonstrated that a material's superconductivity can be altered by coupling it to an in-built, light-confining cavity. In experiments published in Nature, a team led by Itai Keren at Columbia ...
Phys.org / NASA finds extreme star collision in unlikely spot
A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this ...
Phys.org / Your cat is likely to live longer if you don't let them roam—new study
We all know cats represent a major threat to native animals and birds. Australia's 5.3 million domestic cats kill a total of 546 million animals each year in Australia. What's less well known is allowing your domestic cat ...
Phys.org / US data shows Arctic winter sea ice could break last year's record low
Arctic sea ice is headed for one of its smallest winter peaks on record, an AFP review of U.S. data showed Wednesday, as climate change shrinks the region's frozen cover and heightens geopolitical tensions.
Phys.org / Multi-wavelength observations track bright gamma-ray blazar's three-year cycle
By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a multiwavelength study of a bright gamma-ray blazar known as S5 1044+71. The new study, published Feb. ...
Phys.org / Miniature laser technology could bring lab testing into your home
A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on a centimeter-sized chip, ...
Phys.org / What's it like to be a bat? Scientists develop new solution to the puzzle of animal minds
In 1974, philosopher Thomas Nagel posed a deceptively simple question: "What is it like to be a bat?" His point wasn't really about bats. He was offering a provocative challenge about the limits of understanding another mind: ...
Phys.org / Could ultrasound help save hedgehogs?
Researchers at the University of Oxford have suggested that ultrasound-repellers could help reduce hedgehog deaths caused by cars. The proposal is based on new findings, published in Biology Letters, which demonstrate for ...
