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, ...
Phys.org / Tiny RNA molecules in sperm can have big impact on health of babies
Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is exposed to stress or toxicants, can lead to metabolic and behavioral disorders in his offspring.
Phys.org / Signs of ancient life turn up in an unexpected place
Dr. Rowan Martindale, a paleoecologist and geobiologist at the University of Texas at Austin, was walking through the Dadès Valley in the Central High Atlas Mountains of Morocco when she saw something that literally stopped ...
Phys.org / Meta-analysis challenges the link between economic inequality and mental health
Does living in an unequal society make people unhappy? Not necessarily, reveals the largest study ever conducted on the subject. Nicolas Sommet, a social psychologist and research manager at the LIVES Centre at the University ...
