Phys.org / Shaping carbon fiber with electricity: Wireless voltage pulses drive reversible bending
Controlled manipulation of fibers that are as thin as or even thinner than human hair is a real challenge. Despite technological development, the precise and reversible change of the microfibers' orientation is not easy. ...
Medical Xpress / The 'zombie cell' effect: New study explains chemotherapy resistance in lung and ovarian cancers
Researchers have identified a biological mechanism that helps explain why some lung and ovarian cancers become resistant to chemotherapy, offering insight into why cancers recur. The study, published in Nature Aging this ...
Phys.org / Recycling strategies of fungi can affect how forests store carbon
Some fungi are wasteful, while others recycle—and this can determine how much carbon is stored in a forest. Researchers at Lund University have now revealed how fungi manage their mycelium, the network that builds the structure ...
Tech Xplore / Lithium alternatives? Calcium-ion batteries show strong 1,000-cycle performance in new test
Researchers at The Hong Kong University of Science and Technology (HKUST) have achieved a breakthrough in calcium-ion battery (CIB) technology, which could transform energy storage solutions in everyday life. Utilizing quasi-solid-state ...
Phys.org / Major earthquakes are just as random as smaller ones
For obvious reasons, it would be useful to predict when an earthquake is going to occur. It has long been suspected that large quakes in the Himalayas follow a fairly predictable cycle, but nature, as it turns out, is not ...
Phys.org / Can our pets really say 'I love you'? Science is finding out
Purrs of contentment. Soulful eyes locked on yours over dinner. Valentine's Day? Not for pet owners. For those of us who share our lives with animals, this is a daily—if not exactly romantic—experience. So are the various ...
Phys.org / What dating apps are really optimizing. Hint: It isn't love
In the weeks leading up to Valentine's Day, dating apps typically see a spike in new users and activity. More profiles are created, more messages sent, more swipes logged.
Phys.org / New experiments suggest Earth's core contains up to 45 oceans' worth of hydrogen
Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's suspected to be a major ...
Phys.org / A microfluidic chip for one-step detection of PFAS and other pollutants
Environmental pollutant analysis typically requires complex sample pretreatment steps such as filtration, separation, and preconcentration. When solid materials such as sand, soil, or food residues are present in water samples, ...
Tech Xplore / Rule-breaking discovery reveals new way to strengthen metal in extreme conditions
There's a reason why blacksmiths fire metals before hammering them. Heat always softens metal, making it more malleable and easier to reshape. Or does it? In a surprising new study, Northwestern University engineers discovered ...
Phys.org / The origin of magic numbers: Why some atomic nuclei are unusually stable
For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based directly on the interactions between their protons and neutrons. Published in Physical Review Letters, ...
Phys.org / X-ray platform images plasma instability for fusion energy and astrophysics
Harnessing the power of the sun holds the promise of providing future societies with energy abundance. To make this a reality, fusion researchers need to address many technological challenges. For example, fusion reactions ...
