Phys.org / Spaceflight causes astronauts' brains to shift, stretch and compress in microgravity
Spaceflight takes a physical toll on astronauts, causing muscles to atrophy, bones to thin and bodily fluids to shift. According to a new study published in the journal PNAS, we can now add another major change to that list. ...
Phys.org / Glazed sherds in remote Gobi Desert reveal ancient Persian trade connections
In a study published in the Journal of Archaeological Science: Reports, Dr. Ellery Frahm and his colleagues analyzed two unusual blue-green glazed ceramic sherds discovered in the Gobi Desert in 2016.
Phys.org / New massive hot subdwarf binary discovered
Astronomers report the discovery of a new binary system, designated LAMOST J065816.72+094343.1. The newfound binary consists of a massive and hot subdwarf and an unseen companion. The finding was detailed in the January issue ...
Phys.org / Recovering tropical forests grow back nearly twice as fast with nitrogen
Young tropical forests play a crucial role in slowing climate change. Growing trees absorb carbon dioxide from the air, using photosynthesis to build it into their roots, trunks, and branches, where they can store carbon ...
Phys.org / Hygienic conditions in Pompeii's early baths were poor, according to isotope analysis
The city of Pompeii was buried by the eruption of Mount Vesuvius in AD 79. Researchers at Johannes Gutenberg University Mainz (JGU) have now reconstructed the city's water supply system based on carbonate deposits—particularly ...
Phys.org / A protein found in the GI tract can neutralize many bacteria
The mucosal surfaces that line the body are embedded with defensive molecules that help keep microbes from causing inflammation and infections. Among these molecules are lectins—proteins that recognize microbes and other ...
Phys.org / Enthusiasts used their home computers to search for ET—scientists are homing in on 100 signals they found
For 21 years, between 1999 and 2020, millions of people worldwide loaned UC Berkeley scientists their computers to search for signs of advanced civilizations in our galaxy.
Phys.org / A tiny mouse hints at why some mammal mothers may benefit from choosing more than one father
Many animals do something that still surprises researchers: females often mate with more than one male. This behavior—polyandry—has long raised a blunt question. Why divide offspring among multiple fathers, and does it ...
Phys.org / A centuries-old debate on how reptiles keep evolving skin bones is finally settled
Our bones did not begin deep inside the body. They started in the skin, not long after the first complex animals took shape.
Phys.org / Scientists demonstrate low-cost, high-quality lenses for super-resolution microscopy
Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical components that enable super-resolution imaging, with each lens costing less than $1 to produce. The ...
Phys.org / When 'no-effect' isn't safe: Safe chemicals turn toxic in combination across generations
Researchers at National Taiwan University reveal that combined exposure to polystyrene nanoplastics and the preservative butylparaben, at a level considered safe on their own, can cause heritable harm, disrupting reproduction ...
Phys.org / First standalone spin-wave chip operates without external magnets for future telecom
The Politecnico di Milano has created the first integrated and fully tunable device based on spin waves, opening up new possibilities for the telecommunications of the future, far beyond current 5G and 6G standards. The study, ...
