Phys.org / Sideways discovery rewrites the rules of antigen presentation
A new discovery about how cells communicate with each other in the body's immune system has revealed deeper insights for an international team of scientists into fundamental immune system function.
Phys.org / When tropical oceans were oxygen oases
Research reveals when and why ancient tropical seas transitioned from oxygen oases to marine dead zones, providing clues to the long-term evolution of oceanic environments.
Phys.org / X-ray four-wave mixing captures elusive electron interactions inside atoms and molecules
Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, opens a new way to see ...
Phys.org / Exploring mutations that spontaneously switch on a key brain cell receptor
Many people are familiar with histamine, a biological molecule that serves as a key driver of allergic reactions and other immune responses. However, histamine is also a major neurotransmitter in the mammalian brain, regulating ...
Phys.org / Biomass-derived furans offer sustainable alternative to petroleum in chemical production
A research project conducted by the Max-Planck-Institut für Kohlenforschung shows how biomass can be used as a raw material for chemical products instead of petroleum. The scientists have published their findings in the ...
Phys.org / Wormholes may not exist—we've found they reveal something deeper about time and the universe
Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.
Phys.org / Construction emissions are higher than thought—but the solution isn't building less, new study finds
Many cities are making great strides in the fight against climate change, such as improving building energy efficiency, reducing traffic congestion and switching to renewable power sources. But there is another often overlooked ...
Phys.org / Collapse of the Tang dynasty: Climate change likely played a role
Environmental phenomena and their consequences can disrupt social structures and destabilize political systems. An interdisciplinary research team demonstrated this using the example of the late Tang dynasty in medieval China.
Phys.org / Earth system models overestimate river flow increases, research reveals
Understanding how water moves through the Earth system is fundamental to predicting climate impacts and ensuring sustainable water management. Yet despite decades of research, uncertainties persist regarding how global precipitation ...
Phys.org / Large parts of the tropics overlooked in environmental research, study says
Environmental research in the tropics is heavily skewed, according to a comprehensive study led by Umeå University. Humid lowland forest ecosystems receive a disproportionate amount of attention, while colder and drier regions ...
Phys.org / Ancient Type II supernova discovered from universe's first billion years
Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new Type II supernova. The newly detected supernova, named SN Eos, exploded when the universe was only 1 billion years old. ...
Phys.org / Antarctic submillimeter telescope enables more complete view of the carbon cycle in star-forming regions
Chinese researchers have braved the cold and harsh environment of Antarctica in order to get a unique view of star formation in the interstellar medium (ISM). The Chinese National Antarctica and Arctic Research Expedition ...
