Phys.org / Wounds may trigger 'aged' cells within hours, reshaping how senescence starts
What if a process we associate with aging actually helps the body heal? A study led by Mikolaj Ogrodnik, LBI Trauma, published in Nature Cell Biology, shows that cells enter a state of senescence within minutes to hours after ...
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 / From hybrids to 'virgin birth,' stick insects reveal stepwise loss of sex
The evolution of sex remains one of biology's greatest puzzles. While sexual reproduction dominates across the animal kingdom, scientists still debate why it persists despite its high costs. Even more mysterious is the loss ...
Phys.org / Low-cost method uncovers conical intersections that steer light-driven molecular reactions
Conical intersections are crucial molecular switching points in light-driven reactions, but accurately predicting them usually requires computations. A researcher from Shibaura Institute of Technology has developed a new ...
Phys.org / Precise polymer 'knots' uncover hidden slack for designing ultra-tough and responsive smart materials
From household plastic packaging to the flexible frameworks that support wearable electronics, polymer materials form the invisible backbone of modern life. At a microscopic level, polymers consist of long, ribbon-like molecular ...
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 / Two decades of data show that climate change is transforming Biscayne Bay to be warmer, saltier and more acidic
Climate change and sea level rise are altering the chemistry of Biscayne Bay in ways that could threaten South Florida's coastal ecosystems, water resources, fisheries, and recreation, according to a study led by scientists ...
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 / 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 / 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 / Microbes turn biodiesel byproduct into three nylon building blocks, opening greener route
Nylon is a representative plastic material used throughout our daily lives, from clothing to automobiles. However, most of its raw materials have been produced through petrochemical processes, resulting in large carbon emissions. ...
Phys.org / Understanding how things connect helps people invent, 1,200-player experiment suggests
Our capacity for innovation, rather than being the work of random variation, is based on an intrinsic understanding of how the world works, claim Karolinska Institutet and Vrije Universiteit Amsterdam researchers in a new ...
