Phys.org / How tuberculosis bacteria use a 'stealth' mechanism to evade the immune system
Scientists have uncovered an elegant biophysical trick that tuberculosis-causing bacteria use to survive inside human cells, a discovery that could lead to new strategies for fighting one of the world's deadliest infectious ...
Phys.org / Sometimes less is more: Messier nanoparticles may actually deliver drugs more effectively than tightly packed ones
The tiny fatty capsules that deliver COVID-19 mRNA vaccines into billions of arms may work better when they're a little disorganized. That's the surprising finding from researchers who developed a new way to examine these ...
Phys.org / A low-cost microscope to study living cells in zero gravity
As space agencies prepare for human missions to the moon and Mars, scientists need to understand how the absence of gravity affects living cells. Now, a team of researchers has built a rugged, affordable microscope that can ...
Phys.org / Greenland ice melt surges unprecedentedly amid warming
A study led by the University of Barcelona and published in the journal Nature Communications shows that climate change has profoundly altered extreme episodes of melting in the Greenland ice sheet by making them more frequent, ...
Tech Xplore / New perspective charts path to next-generation water and energy membranes
When you turn on a faucet, charge an electric vehicle or use products made with clean hydrogen, you may not realize that membranes—ultrathin films perforated with pores too small to see—make these modern processes possible. ...
Medical Xpress / Scientists discover why we know when to stop scratching an itch
When you scratch an itch, something tells your brain when to stop. That moment of relief, when scratching feels "enough," is not accidental. Scientists have now identified a key molecular and neural mechanism behind this ...
Phys.org / Are one in 200 men really related to Genghis Khan? Maybe not, according to a new study
In present day Kazakhstan, both local folklore and genetic evidence found buried in royal tombs have shone a light on the region's ties to Genghis Khan and the Mongol Empire. New DNA analysis of ruling elites from the Golden ...
Medical Xpress / Abortion restrictions increase deaths among expecting and new moms, researchers report
Anti-abortion laws are associated with more deaths among expecting and new mothers, a new study says.
Phys.org / Earliest evidence of indigo-dyed textiles and single-needle knitting discovered in Bronze Age Anatolia
A research team led by Assoc. Prof. Dr. Çiğdem Maner from Koç University's Department of Archaeology and History of Art has uncovered remarkable textile fragments at Beycesultan Höyük that rewrite our understanding of ...
Phys.org / New microscopy technique lets scientists see cells in unprecedented detail and color
Scientists have developed a new imaging technique that uses a novel contrast mechanism in bioimaging to merge the strengths of two powerful microscopy methods, allowing researchers to see both the intricate architecture of ...
Phys.org / How your body senses cold—and why menthol feels cool
When you step outside on a winter morning or pop a mint into your mouth, a tiny molecular sensor in your body springs into action, alerting your brain to the sensation of cold. Scientists have now captured the first detailed ...
Phys.org / For thousands of years, solar eclipses have been associated with the fate of rulers
The moon crossed the sun's path on February 17, causing what is known as an annular solar eclipse. The sun was not covered completely, but the moon blocked enough of its light to leave a fiery ring. Unless you're deep in ...
