Phys.org / Manganese's emission lines shine a light on galactic evolution
In a new study, a team of astronomers has identified wavelengths of light that could be useful for tracing the chemical evolution of the universe. Using computational modeling to simulate how electrons interact with manganese ...
Phys.org / Small-plane fuel raises lead levels up to sevenfold near Oregon airports, study suggests
Emissions from aircraft that use leaded aviation gasoline are a significant source of environmental pollution in neighborhoods near regional airports, according to a new study by researchers at Oregon State University and ...
Phys.org / Antarctica is home to microbes found nowhere else on Earth
Scientists have often wondered about species that are unique to Antarctica. But the focus has mainly been on animals, like feathery penguins. CIRES researchers wanted to dig deeper—into the soils—believing tiny organisms ...
Phys.org / Caught right-handed: Mystery of coiling snake embryos explained
An international team led by Canadian researchers has found evidence explaining why snake embryos form a curious spiral. This ability to coil as embryos enables snakes to hatch with the longest bodies of all vertebrates.
Phys.org / Managing chronic conditions together may be key to longer lifespan, canine study finds
As dogs age, many develop more than one chronic health condition. New research from Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) shows those conditions can dramatically shorten a dog's lifespan, ...
Phys.org / Solar orbiter detects ion sorting at the solar wind's magnetic boundary
A Southwest Research Institute (SwRI) study of data from the European Space Agency's (ESA) Solar Orbiter gives the most detailed view of the heliospheric current sheet (HCS) to date. The HCS is a sprawling, undulating surface ...
Phys.org / Tiny mirror that controls light in 3D could make microscopes smaller and faster
Researchers use tightly focused laser beams to image biological samples, shape materials with microscopic precision and generate displays. But using those beams in three dimensions requires more than sweeping light from side ...
Phys.org / Even small amounts of ocean plastic can affect petrel chicks
Ocean plastic pollution is accidentally on the menu for southern giant petrel chicks. Even small nibbles of it may affect their physiology during development, according to a study from the University of California, Davis, ...
Phys.org / Important role of plastid ion channels in plant stress response identified
When plants are attacked by herbivores or pathogens, they must respond rapidly while also preparing for potential future attacks. Calcium, a cellular second messenger, and the plant hormone jasmonic acid play important roles ...
Phys.org / Keeping cool saves thousands of lives yearly, but at a cost of worsening global warming, experts say
Cooling from air conditioning saves lives—more than 5,000 a year in the United States alone—but it also heats up the planet and taxes our electrical grid, scientists say.
Phys.org / The mystery of a well-traveled kissing bug
On an August morning last year, an American couple soon to embark on a European river cruise awoke in a luxury hotel in Lisbon.
Phys.org / Beyond flood maps: Puerto Rico residents seek climate tools built around local needs
Resources such as sea level rise viewers, heat maps and flood prediction services are crucial tools in a changing climate. NASA Earth Observations (NASA EO) datasets provide important information on these and other natural ...
