Phys.org / African grasslands expanded 5 million year earlier than previously thought, molecular fossils suggest
The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, and how will they change in the future? Ongoing warming, rising ...
Phys.org / Space travel doesn't affect the strength of heart muscle cells, study finds
It's common to see images of astronauts on the International Space Station exercising, running on special treadmills and pedaling cycles designed for tight quarters.
Phys.org / Spontaneous magnons synchronize with external signals at room temperature
Signals ride on waves of one kind or another: light, sound, radio. But new carriers are needed to relay information in next-generation devices. Disturbances or waves in magnetic materials called magnons could be an efficient ...
Phys.org / Pain isn't the point: European viper venoms may have evolved to subdue prey
For many people, the fear of venomous snakes is linked to one thing: pain. Yet new research led by scientists at Bangor University suggests that, for Europe's vipers, at least, causing pain may never have been a driving force ...
Phys.org / Soil-dwelling myxobacteria reveal five new classes of bioactive compounds
Most antibiotics used clinically are based on natural compounds produced by bacteria and other microorganisms. At the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS), researchers are using soil-dwelling myxobacteria ...
Phys.org / First supernovae may have seeded rocky planet building blocks 100 million years after the Big Bang
The building blocks of rocky planets may have begun forming just 100 million years after the Big Bang—long before the first galaxies even existed—according to new research from the University of Portsmouth.
Phys.org / Single synthetic peptide forms electrically polarized, self-healing hydrogel
Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) and RIKEN Pioneering Research Institute (PRI) in Japan, together with collaborators from the University of Münster, Germany, have developed a new hydrogel ...
Phys.org / Sugar swap simplifies production of promising targeted cancer therapies
Researchers at the University of Wisconsin–Madison have developed a simpler way to produce a fast-growing class of targeted cancer therapies, a discovery that could make the medicines easier to manufacture consistently while ...
Phys.org / New frog species discovered in the Amazon's flooded forests
Scientists from Brazil and other countries have discovered a new species of frog in the flooded forests of the western Amazon. They named it Adenomera varcena. This finding significantly advances our understanding of Amazonian ...
Phys.org / Hybrid bioprinter creates capillary networks narrower than 10 micrometers
More than 100,000 people are awaiting an organ transplant in the United States, with a new candidate added to the list every 10 minutes. Even if the transplant is carried out successfully, recipients must take immunosuppressive ...
Phys.org / When male suitors abound, female treefrogs have trouble picking mates
Much like an indecisive single person on a dating app, female treefrogs struggle to pick the most desirable mates when they have too many options to choose from. According to a new study published Aug. 12 in the journal iScience, ...
Phys.org / How to design a space habitat that supports its residents' mental health
In extreme environments, habitats are built for survival. Submarines, Antarctic bases and post-disaster dwellings are designed to prioritize health and safety. This is especially the case for habitats in space, where room ...
