Phys.org / Measuring movement creates a new way to map indoor air pollution
University of Birmingham scientists have developed a new way of measuring and analyzing indoor air pollution that—in initial trials—has established a clear link between office occupancy, physical activity, and air quality.
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 / Sparse tongue hair explains why queen bees stop foraging when workers emerge
During spring, when queen bumblebees first emerge from hibernation to start their nests, they work incredibly hard foraging for nectar to fuel their new colonies. But then, as soon as their first workers are born, they seem ...
Phys.org / Scientists realize a three-qubit quantum register in a silicon photonic chip
Quantum technologies are highly promising devices that process, transfer or store information leveraging quantum mechanical effects. Instead of relying on bits, like classical computers, quantum devices rely on entangled ...
Phys.org / Asexual yam species employs mimicry to trick birds and spread farther
Evolutionarily speaking, the ultimate goal of a lifeform is to reproduce and stave off extinction. Many plants and animals have evolved unique tricks to do so. One of these tricks is mimicry, which might be used to trick ...
Phys.org / Massive impact could be the cause of our lopsided moon
Our nearest neighbor, the moon, is still something of a mystery to us. For decades, scientists have wondered why it appears so lopsided, with dark volcanic plains on the near side (the side we see) and rugged, cratered mountains ...
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 / Microbubbles can release microplastics into our water
Microbubbles in the tap water you just poured into a plastic glass are strong enough to create tiny abrasions on the inner layer of the plastic—quietly adding to our growing microplastic problem.
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 / 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 / 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 ...
