Medical Xpress / For real heart protection, the weekly exercise number climbs far beyond current advice
Adults should aim to do between 560 and 610 minutes a week of moderate to vigorous physical activity to achieve a substantial reduction in the risk of heart attacks and stroke, suggest the findings of an observational study ...
Phys.org / Scientists discover thriving hard-substrate fauna in Oceania's deep sea
In the crushing darkness of the hadal zone—deep ocean trenches plunging 6,000 m to nearly 11,000 m—scientists have uncovered a hidden community. A study published in Science on May 14 reports the discovery of a protist-dominated ...
Phys.org / Nickelate reveals nodeless gap, providing key clue to high-temperature superconductivity
The mechanism of high-temperature (TC) superconductivity is a key challenge in condensed matter physics. Recently, Chinese scientists made significant progress in the study of high-TC nickelate superconductors.
Phys.org / Atlas reveals rocks with rare earth element potential, helping pinpoint new deposits
A new atlas charts the global distribution of unusual, critical-metal-bearing igneous rocks, finding that they often form near the thick and ancient cores of the world's major continents. Researchers from Cambridge's Department ...
Phys.org / Key switch controlling soil fungi symbiosis could solve a longstanding agricultural problem
Over the course of evolution, plants have developed an elegant strategy to counteract a lack of phosphate in the soil—they form symbiotic relationships with soil fungi. These mycorrhizal fungi efficiently supply their plant ...
Phys.org / The impact of microplastics on ocean carbon uptake
Marine microplastics affect algae's ability to grow and photosynthesize. Researchers have now calculated what impact this has on the greenhouse effect and the ocean's ability to absorb carbon dioxide.
Phys.org / Overpopulation can impair fertility. A new study explains why
Scientists have reported it for decades: overpopulation can impair reproduction. Crowded chickens lay fewer eggs. Crowded mice have smaller broods. In humans, several studies have associated increased population density with ...
Medical Xpress / Ebola toll tops 200, other African countries seen at risk
Officials in the Democratic Republic of Congo updated the death toll from the Ebola outbreak to 204 late Saturday, hours after the Red Cross said three volunteers had died there and Uganda confirmed three new Ebola cases.
Phys.org / Bees found an unlikely new food source, and it could reshape how a destructive forest disease travels
New research published in NeoBiota has found that the Western honey bee—an introduced species to Australia—and the devastating, invasive plant fungus known as myrtle rust (Austropuccinia psidii) may have formed a mutually ...
Phys.org / Some technologies use accelerated natural processes to capture carbon, but can they store it durably?
Natural geological processes have been regulating Earth's climate for millions of years. Accelerated versions of these processes are now being promoted as technologies to draw down carbon from the atmosphere—and some are ...
Phys.org / Understanding the mechanisms of collective cell movement
Like schools of fish and flocks of birds, our cells can also migrate collectively in coordination with their neighbors. This harmonious movement of cells occurs during embryonic development, wound healing, and cancer metastasis. ...
Medical Xpress / How the gut rewires the brain to drive cravings for essential nutrients
Eating is not only about getting enough calories. Animals also need to choose the right nutrients. When the body lacks protein, it must seek essential amino acids—the protein building blocks that cannot be made internally ...
