Phys.org / A Hall 'rectenna' can detect signals over a 100 GHz frequency range
Many current wireless communication, imaging and sensing technologies rely on components that convert oscillating electric and magnetic fields (i.e., electromagnetic waves) into electrical signals. Some of the most used components ...
Phys.org / Stolen chloroplasts maintained by host-made proteins offer clues to plant cell origins
Every plant cell is the product of a biological merger billions of years ago. Chloroplasts are key structures in plants and algae that capture sunlight, but originally they were free-living bacteria that took up residence ...
Phys.org / Snow flies produce bursts of heat and proteins to avoid freezing, new study finds
In a new study, Northwestern University scientists explored how snow flies—small, wingless insects that crawl across snow to find mates and lay eggs—survive in freezing cold temperatures. They discovered this snow-dwelling ...
Phys.org / XRISM identifies gamma Cas X-ray origin, solving a 50-year-old stellar mystery
Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary ...
Phys.org / Preparing for the next pandemic: Scientists discover a new class of influenza antivirals
Researchers from Leiden University, University of York, University of Barcelona/IQTCUB/ICREA and The Francis Crick Institute report a new class of experimental compounds that powerfully block influenza viruses. The findings ...
Phys.org / Ancient 'syphilis-like' disease in Vietnam challenges long-held assumptions on congenital infection
The findings of a new study by a Charles Sturt University researcher and colleagues challenge a long-standing assumption used by scientists studying ancient disease. The study is published in the International Journal of ...
Medical Xpress / Well-fed penguins live longer but age faster—much like modern humans
In public discourse, the increasing lifespan in Western countries is often linked to longer life in good health. However, studying human aging in modern societies is complex because outcomes are shaped by numerous social, ...
Phys.org / Novel approach allows studying the DNA of otters without disturbing them
Studying endangered animal species without disturbing them and disrupting their natural habitat could be highly advantageous, as it would contribute to their protection and prevent unnecessary stress. Conventional methods ...
Phys.org / China's earliest Bronze Age meteoritic iron artifact unearthed at Sanxingdui sacrificial site
In a study published in Archaeological Research in Asia, Dr. Haichao Li and a team of researchers analyzed the earliest Bronze Age meteoritic iron artifact from southwestern China, the largest found to date in the country. ...
Phys.org / Magnetic microbots steer quantum sensors inside living cells
Cells are squishy and soft. Tiny nanometer-sized particles such as quantum sensors cannot move freely inside them due to viscous drag, which makes sensing challenging. Researchers at the Indian Institute of Science (IISc) ...
Phys.org / New lipid nanoparticle design improves precision of mRNA vaccine delivery
Penn Engineers have redesigned a key component of lipid nanoparticles (LNPs), the delivery vehicles behind mRNA vaccines, to steer the particles toward lymph nodes while reducing off-target delivery to the liver. The advance ...
Tech Xplore / Sensor chips help identify deepfakes by adding cryptographic signatures to camera data
AI-generated images and videos pose a threat to democratic processes and undermine trust within society. Researchers at ETH Zurich have now developed chip technology that enables verification of the authenticity of sensor ...
