Tech Xplore / No batteries, just body heat: Demonstrating the potential of battery-free sensing
As devices for wireless sensing systems become smaller and more complex, finding suitable power sources for them is becoming increasingly difficult. However, advances in low-power sensing technology may allow such systems ...
Phys.org / Hemp-based thermoplastic offers a greener alternative to plastic packaging
As the global pollution crisis caused by manufacturing and disposing of single-use plastics continues to grow, researchers have developed a non-toxic plastic alternative derived from the hemp plant—a non-psychoactive type ...
Phys.org / AI discovery reveals DNA isn't locked away in cells after all
Every cell in the human body squeezes over six feet of DNA into a minuscule speck invisible to the naked eye—like compressing a whole house into a single sugar cube. In order to fit in a cell and remain organized, DNA is ...
Phys.org / Light-activated protein illuminates when embryos can cope with disruptions to cell division
Cell division during the early stage of embryo development is a trade-off between speed and accuracy; the cells need to divide quickly to enable rapid growth, but it's important not to introduce errors that could be fatal ...
Medical Xpress / T cells secrete DNA to boost the immune system's cancer-fighting ability
Activated immune cells secrete tiny capsules bearing DNA that can enter other immune and tumor cells to stimulate the body's defense systems, according to a study led by investigators at Weill Cornell Medicine. The discovery ...
Phys.org / Carbon credits have enabled vital protection of tropical forests—despite being oversold 10-fold
A major analysis led by the University of Cambridge has found that many REDD+ projects achieved meaningful reductions in forest loss—offering real environmental benefits. This is despite the study confirming that almost 11 ...
Phys.org / With a swipe of a magnet, microscopic 'magno-bots' perform complex maneuvers
Under a microscope, a bouquet of lollipop-like structures, each smaller than a grain of sand, waves gently in a Petri dish of liquid. Suddenly, they snap together, like the jaws of a Venus flytrap, as a scientist waves a ...
Tech Xplore / Perovskite solar cells skip yellow phase, degrade more slowly with key additives
Halide perovskites are gaining ground on silicon as a critical material for solar cell technologies: A new study published in the journal Science reports a method to make perovskite-based photovoltaics more durable, allowing ...
Phys.org / Standardized runoff dataset could improve forecasts of urban microplastic pollution
As rain falls, lurking within stormwater runoff are hidden microplastics, polluting the water sources they drain into. Even though microplastics originate in urban environments such as cities, existing data sets focus on ...
Phys.org / How rocks trap CO₂ faster: Water-driven pathway could speed long-term carbon storage
Rocks can bind carbon dioxide—and much faster than previously thought. For a long time, it was assumed that the transformation of CO2 into carbonate rock depends on very slow, time-consuming processes. According to that view, ...
Phys.org / Decades-long study finds 'stable' soil carbon degrades
After nearly four decades, the world's longest-running soil warming experiment is revealing a surprising result: even "stable" carbon in forest soils can break down as temperatures rise, releasing more CO₂ into the atmosphere. ...
Phys.org / Airborne desert dust may warm climate far more than expected, new analysis shows
Atmospheric dust plays a dual role in Earth's climate: it reflects some sunlight back into space while also absorbing and retaining the planet's heat like an insulating blanket. But while dust likely cools the planet overall, ...
