Phys.org / An anomaly in global sea level rise is explained by deep ocean heating
Climate scientists like to keep their accounting books neat and balanced. As climate change alters energy flows all across the planet, which in turn causes effects like sea level rise, ice melt and more, keeping close track ...
Phys.org / Organic matter diversity determines how much iron is available for marine life, study finds
How much of the essential trace element iron remains available for marine life in the ocean depends critically on the diversity of organic molecules in seawater, according to new research published in Nature Communications ...
Phys.org / Tiny DNA fragments, big agricultural insights: New genomic approach helps improve crop resilience
The genes that could help the world's crops survive drought, heat, and disease probably already exist. But much of this genetic diversity remains hidden within ancient plant varieties and forgotten seed collections, among ...
Phys.org / A mechanical blue LED: Stretching GaN shifts light from UV to blue without changing chemistry
A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical stretching technology to dynamically control the emission color of gallium nitride (GaN) material from ...
Phys.org / Stick-on gel delivers drugs directly to plants to clear infections quickly
A stick-on gel for plants could one day offer a simple, safe and targeted way to treat diseases and pests. Engineers at the University of California San Diego have developed an adhesive gel that can be loaded with substances, ...
Phys.org / They cover just 3% of Earth, yet the unanswered questions around them could reshape climate action forever
Researchers including a number from the University of Exeter, have identified the most urgent unanswered questions about peatlands, providing a global roadmap to guide future science and policy for one of the planet's most ...
Phys.org / Soil, not fertilizer, is primary source of nitrogen gas loss in rice paddies, study reveals
Rice production is heavily dependent on nitrogen fertilizers, particularly in China, where application rates are two to three times the global average. At the same time, a large amount of nitrogen is lost to the environment—mainly ...
Phys.org / ALMA reveals giant molecular clouds across Needle galaxy's full disk
An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to perform high-resolution observations of the Needle galaxy. Results of the new observational campaign, presented ...
Phys.org / For decades, this bias test looked inside minds—now its biggest blind spot is coming into focus
People are known to implicitly create connections between different things or ideas in their mind, some of which can influence how they perceive others, themselves and the world at large. These implicit biases have been widely ...
Phys.org / AI slashes the time needed to design better heat-harvesting devices
From wearable technology to industrial heat recovery, thermoelectric generators which convert waste heat into electricity have an enormous range of potential applications. So far, however, designing high-performing versions ...
Phys.org / Data from Earth's most remote atoll show soil fungi are key to island regeneration
Palmyra Atoll, a remote, uninhabited speck of land, coral and sea halfway between Hawaii and American Samoa, is one of the healthiest, intact atolls on the planet—so ecologically sensitive that visiting researchers freeze ...
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 ...
