A robot dog makes short work of a bombMinistry of DefenceWe've seen robot dogs perform all kinds of unusual tasks, but what about using them to enhance safety? The British Ministry of Defence is deploying these mechanical canines to improve the efficiency and safety of bomb detection and defusal.While bomb disposal robots have been...
From the 15th to the 19th centuries, more than 12 million Africans were enslaved and sent to the Americas and Europe. Combining dental records with a map of strontium ratios across sub-Saharan Africa is allowing researchers to pinpoint some slaves' birthplaces.Joseph Swain/Wikimedia CommonsA little-known element is offering new insights into the transatlantic slave trade....
In 1927, physicists gathered to discuss the recent formulation of quantum mechanics, at the Solvay Conference on Physics in Brussels. Many important figures were in attendance, including Werner Heisenberg (back row, third from right) and Erwin Schrödinger (back row, sixth from right.) Albert Einstein is front row center.Pictorial Press Ltd./Alamy Stock PhotoA century ago,...
Weekly egg consumption is associated with a decreased risk of death, a new study has found. Credit: PixabayA recent study reveals that consuming one to six eggs per week significantly lowers the risk of death from any cause, especially heart disease—even among individuals with high cholesterol.The health effects of eating eggs have been debated...
Researchers have discovered a novel way that surface acoustic waves interact with magnetic materials, leading to a surprising asymmetric diffraction effect. This could revolutionize acoustic-based communication technologies. Credit: SciTechDaily.comBy experimenting with nanoscale magnetic materials, researchers have uncovered an asymmetric diffraction pattern in surface acoustic waves (SAWs)—a phenomenon previously seen only in optics. This breakthrough...

Studies indicate that 30-40 minutes of moderate to vigorous activity daily can help counterbalance the risks.How Much Exercise Is Needed to Offset the Effects of Prolonged Sitting?While it's clear that prolonged sitting harms our health,...
Brain tissue from dementia patient (left) with glints of plastic (right). (Nihart, Nature Medicine, 2025)A recent study reveals that postmortem brain samples collected last year contain significantly more microplastics than those analyzed nearly a decade ago, suggesting these synthetic particles accumulate in vital organs over time.Researchers led by University of New Mexico health scientist Alexander...
Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can – if a proper definition of “entropy” is used. Credit: TU WienResearchers at TU Wien have resolved a long-standing paradox in quantum entropy, proving that even in isolated quantum systems, disorder naturally increases, aligning quantum mechanics with thermodynamics.The second law of...
Credit: PixabayScientists at the University of Jyväskylä’s Accelerator Laboratory have precisely measured the atomic masses of radioactive lanthanum isotopes, uncovering an unexpected anomaly in their nuclear binding energies. This discovery sheds light on the formation of elements heavier than iron and raises questions about nuclear structure.At the IGISOL facility, researchers produced short-lived, neutron-rich lanthanum...
(mycan/Getty Images)A team from the University of Science and Technology of China tested a quantum paradox by measuring light in 37 dimensions, exploring the Greenberger-Horne-Zeilinger (GHZ) paradox. Their findings provide insights into quantum phenomena and technologies, revealing how difficult it is for our brains to understand the universe’s workings. While local realism predicts a...
