Phys.org / Human sperm may get lost in space
Having a baby in space may require a bit more direction, with new Adelaide University research revealing the navigational abilities of sperm are negatively impacted by a lack of gravity. Researchers at the University's Robinson ...
Phys.org / Hubble detects first-ever spin reversal of tiny comet
Astronomers using NASA's Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the ...
Phys.org / How Neanderthals used a lakeshore in Germany to hunt, butcher and survive
In 1948, a group of amateurs led by a local headmaster in Lehringen, Germany, uncovered the skeleton of a straight-tusked elephant—the largest land mammal known to have roamed Europe—in 125,000-year-old sediments from the ...
Phys.org / Fieldoscopy reveals femtosecond optical switching in 15 nm indium tin oxide nanocrystals
Just as an antenna interacts with radio waves, light interacts with metallic nanostructures. Therefore, understanding how a structure influences field oscillations provides valuable insights into the structure's physical ...
Phys.org / Novel measurement confirms a 50-year-old prediction: Dark points are faster than light
A research group from the Technion-Israel Institute of Technology reports in Nature an unprecedented achievement in electron microscopy: the direct measurement of "dark points" within light waves. By doing so, the researchers ...
Phys.org / New framework suggests dark energy could be evolving—and may be linked to the Hubble tension
A team of cosmologists in China has introduced a mathematical framework that investigates two of the deepest mysteries in cosmology at the same time. Publishing their research in The Astrophysical Journal, Yun Chen and colleagues ...
Phys.org / Tale of the lava heron: Student describes new Galapagos species
The Galapagos Islands are famous for the discoveries that shaped Charles Darwin's theory of evolution. Now an SFSU graduate has added one more: Ezra Mendales (M.S., '23) describes a new species as part of his master's thesis. ...
Phys.org / Giant virus DNA may help polar algae survive harsh environments
In the game of survival, you can't always go it alone. Tiny algae living in the harsh conditions of the world's polar oceans appear to be better able to withstand the cold, high salinity, and extreme UV radiation, thanks ...
Phys.org / Tiny LED design could power next-generation technology
From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing so in a cost-effective and efficient way, however, is often a formidable task. In an article published ...
Medical Xpress / Small RNAs offer new clues to schizophrenia and bipolar disorder
For decades, scientists studying brain disorders have focused almost exclusively on proteins and the genes encoding them. Now, research from Thomas Jefferson University's Computational Medicine Center suggests that several ...
Phys.org / Experimental evidence shows how photons spread across multiple paths in an interferometer
The nature of quantum particles has long puzzled scientists. While single-particle interference suggests that a photon can behave like a spread-out wave, a whole photon is only ever detected in one specific place. Traditional ...
Phys.org / Bioluminescent bacterial partner proves essential for squid development
The Hawaiian bobtail squid, a small, multi-colored native of coastal waters in Hawai'i, uses bioluminescence to camouflage itself and evade predators. However, the costume change is only possible through an exclusive symbiotic ...
