Phys.org / New study identifies sequence of critical thresholds for Antarctic ice basins
The Antarctic ice sheet does not behave as one single tipping element, but as a set of interacting basins with different critical thresholds. This is the finding of a new study by the Potsdam Institute for Climate Impact ...
Phys.org / Microscopic mirrors for future quantum networks: A new way to make high-performance optical resonators
Researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Faculty of Arts and Sciences have devised a new way to make some of the smallest, smoothest mirrors ever created for controlling ...
Phys.org / Rewriting our understanding of early hominin dispersal from Africa to Eurasia
What if Homo erectus (H. erectus), the direct ancestor of modern humans, arrived in China much earlier than we thought? Research published in Science Advances may rewrite our understanding of early human dispersal in that ...
Phys.org / Feeling worse about money? Climate change may be part of the reason
Climate change is not just reshaping the planet, it's already affecting how people feel about their lives, their health and their financial security, according to a new study from the Universities of Portsmouth and Dundee. ...
Phys.org / Solving a longstanding mystery about complex life's origin—oxygen-tolerant Asgard archaea may explain eukaryotes' rise
The most widely accepted scientific explanation for the arrival of all complex life on Earth has had an unsolved mystery at its heart. According to the theory, all plants, animals and fungi, known collectively as eukaryotes, ...
Phys.org / Cosmic predators: How supermassive black holes slow star growth in nearby galaxies
Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies millions of light-years ...
Phys.org / Antarctic warming is altering atmospheric stability: New evidence from the 1950s to the present
A new study published in the Journal of Climate reveals how surface warming in Antarctica, particularly over the Antarctic Peninsula, is significantly altering the stability of the lowest layers of the atmosphere.
Phys.org / Exposing a hidden anchor for HIV replication
The tiny shell protecting the HIV virus resembles a slightly rounded ice cream cone, but there is nothing sweet about it. More than 40 million people worldwide live with AIDS because of this virus, and treatments must continually ...
Phys.org / Simplifying quantum simulations—symmetry can cut computational effort by several orders of magnitude
Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the number of possible ...
Phys.org / Eclipse research finds turbulent times in the sun's corona
Researchers at the University of Hawaiʻi have uncovered new clues about how energy moves through the sun's outer atmosphere, using one of nature's rarest events as their window: total solar eclipses. Drawing on more than ...
Phys.org / Ultrasound-jiggled nanobubbles can crack cancer's collagen 'fortress'
Researchers at Case Western Reserve University have discovered a way to breach one of cancer's most stubborn defenses: the impenetrable fortress that solid tumors build around themselves.
Phys.org / Quantum-level effects in biology: Weak magnetic fields and isotopes can alter cell protein structures
A novel method to manipulate the inner structure of cells connects several scientific fields and could represent a significant step in the treatment of neurodegenerative diseases, such as Alzheimer's and Parkinson's disease. ...
