Phys.org / Europe's Late Neanderthals descended from a single population, DNA analysis suggests
A study incorporating new DNA data and archaeological evidence has shown that the last Neanderthals in Europe experienced a major population turnover, resulting in little diversity in their gene pool prior to their disappearance ...
Phys.org / AI approach uncovers dozens of hidden planets in NASA's TESS data
Astronomers at the University of Warwick have validated over 100 exoplanets, including 31 newly detected planets, using a new artificial intelligence tool applied to data from NASA's Transiting Exoplanet Survey Satellite ...
Phys.org / The hidden cost of sperm storage: Ejaculates found to deteriorate across the animal kingdom
Current World Health Organization (WHO) guidelines typically recommend two to seven days of abstinence before taking semen samples or assisted reproduction. However, a new study led by Oxford University researchers suggests ...
Phys.org / Red-tailed bumblebees found to be key hosts for dangerous bee virus
Wild bumblebees serve as key hosts for acute bee paralysis virus. While the virus appears to cause little harm to bumblebees, infection is usually fatal to honeybees. Until now, it was assumed that honeybees were the key ...
Phys.org / A spinel crystal structure exhibits unusual, pressure-induced superconductivity
Superconductors are materials that conduct electricity with an electrical resistance of zero. Superconductivity is generally observed when materials are cooled down to extremely low temperatures. In some cases, however, like ...
Phys.org / Trapped subsurface heat may have triggered Antarctica's sudden sea ice loss
In 2016, Antarctic sea ice, which had previously shown record expansion, shifted rapidly toward unusually low levels. This abrupt shift left scientists scratching their heads, wondering why it had vanished so quickly despite ...
Phys.org / Bio-based polymer offers a sustainable solution to 'forever chemical' cleanup
Researchers at the University of Bath have discovered a renewable, bio-based polymer membrane capable of efficiently capturing toxic "forever chemicals" from water, offering a potential new route to more sustainable water ...
Phys.org / 600-year-old pinot noir grape found in medieval French toilet
A 600-year-old grape seed discovered in the toilets of a medieval French hospital is genetically identical to the grapes still being used to make pinot noir wine, scientists said Tuesday.
Phys.org / Electronics of the future: Ultra-efficient graphene switch developed at nanometer scale
A team of researchers from Tel Aviv University, in collaboration with colleagues from Japan, has taken an important step toward the next generation of electronics. The scientists achieved highly precise control of the internal ...
Phys.org / Boys ditch books when schools close—girls keep reading: Study
When holidays or pandemics shut down schools, gender differences in children's reading habits widen; boys stop reading, while girls continue, according to a new study from the University of Copenhagen. The researchers say ...
Phys.org / Agricultural soils exposed to controversial weedkiller may be unexpected breeding ground for hospital 'superbugs'
Each year, antimicrobial resistance (AMR) is responsible for an estimated 1.1 to 1.4 million deaths worldwide. Now, scientists have found evidence that the spread of AMR isn't always driven by bacteria evolving to resist ...
Phys.org / Mammal cloning cannot be endless: Mouse line fails at generation 58
There is a limit on how many times a mammal can be cloned before suffering "mutational meltdown," Japanese scientists have discovered, after making 1,200 clones over two decades that started off with a single mouse.
