Phys.org / Space station dust maps slash climate uncertainty over iron-rich particles
New research from a team of scientists led by Cornell is transforming how researchers understand one of the atmosphere's most abundant and least understood constituents: mineral dust.
Phys.org / Young and unemployed? Remote work, not AI, may be the problem, study finds
The rise of remote work since the pandemic has made businesses more reluctant to hire young, inexperienced workers and is the key driver of higher unemployment rates for recent college graduates, a study released Monday has ...
Phys.org / Cold-grown plankton shells sharpen Arctic climate reconstructions
Researchers at iC3 have found a way to improve records of past high latitude ocean change using tiny plankton shells called foraminifera. By growing these foraminifera under controlled cold-water conditions, the team has ...
Phys.org / Low-cost workflow creates 100,000 uniform cell capsules with standard lab tools
Cells are typically studied outside the body under controlled laboratory conditions. However, conventional flat cell culture methods do not fully reproduce the complex three-dimensional environments that cells experience ...
Phys.org / Researchers discover how to turn one germ's drug resistance into an Achilles' heel
Decades of reliance on the antibiotic rifampicin have fueled the rise of drug-resistant Mycobacterium tuberculosis (Mtb). But as the bacterium mutates to protect itself from the drug, it also creates new weak points that ...
Phys.org / Ancient land plant reveals the evolution of a 400‑million‑year‑old UV‑B protection system
Sunlight provides the energy necessary for photosynthesis and growth, but it also exposes plants to harmful ultraviolet-B (UV-B) radiation. Plants must therefore strike a delicate balance between growth and protection. By ...
Phys.org / Better math discriminates exotic from classical materials
The planar Hall effect is a tabletop diagnostic tool for special quantum properties useful in basic research and technological applications. Or so it was thought, because careful calculation by Kobe University researchers ...
Phys.org / How drought rewires roots, cutting iron uptake across major food crops
New research by scientists at the University of Calgary has found that plants, ranging from canola to rice to tomatoes, actively shut down their own ability to take up iron when they experience drought. It's a finding that ...
Phys.org / Fifty-year protein mystery breaks open as acid-driven water loss comes into view
Proteins systematically lose their protective hydration shell when their environment becomes more acidic. Until recently, this was just a theory. State-of-the-art imaging techniques have helped researchers at Martin Luther ...
Phys.org / 'Molecular movie' technology reveals a better way to thwart environmental pollutant
The latest production from the "molecular movie" imaging technology developed at Oregon State University is a new, inexpensive way of dealing with a common environmental pollutant. Based on short-pulse lasers, the imaging ...
Phys.org / Atmospheric wave theory falls short in explaining rising extreme weather, study suggests
Across much of the northern hemisphere, extreme weather events like heat waves and heavy precipitation have increased in frequency and severity over the last several decades. A new study from the Harvard John A. Paulson School ...
Phys.org / Box jellyfish reveal secret life cycle with implications for coastal safety
Box jellyfish are often feared as dangerous animals, with some species capable of causing severe or even fatal stings. However, box jellyfish nematocysts—organelles responsible for this toxic sting—are theorized to also play ...
