Phys.org / Greenland meltwater adds to AMOC weakening, but updated model finds no tipping point in sight
The state of the Atlantic Meridional Overturning Circulation (AMOC) has been a hot topic among climate scientists in recent years. The AMOC is crucial for climate regulation because it pulls warm surface water from the tropics ...
Phys.org / Optical writing of antiferromagnets points toward new storage devices and energy efficient information systems
A German-Japanese research team involving the University of Augsburg has made a significant breakthrough in the use of antiferromagnets. For the first time, the team has succeeded in writing magnetic information using only ...
Medical Xpress / Memories of childhood trauma remain stable over time but change more often in children than adults
Traumatic memories of childhood maltreatment typically remain consistent over time, according to a major new study led by King's College London and published in Nature Mental Health. The paper focuses on traumatic memories ...
Phys.org / Astronomers may have caught an early galaxy in the process of dying
Astronomers have spotted many "red and dead" galaxies in the early universe. These are massive systems that stopped forming stars surprisingly early in cosmic history. Now, they may have found evidence of one in the act of ...
Phys.org / How proteins are inserted into cell membranes
Researchers from Heinrich Heine University Düsseldorf (HHU) have—in collaboration with colleagues from Ludwig Maximilian University (LMU) in Munich—analyzed the complex biochemical processes that bacteria use to insert proteins ...
Phys.org / Common nanostructures may explain shared photoproperties in two widespread dark materials
A newly developed framework for understanding the photoproperties of both natural organic matter and eumelanin, a natural pigment responsible for dark colors in organisms, may inspire advanced sustainable technologies, scientists ...
Phys.org / A young gull's mottled brown plumage acts as a 'not a threat' signal to territorial adults
Birds are known for their distinctive plumage that helps them attract mates during the breeding season. For some birds, the path to adulthood is quite linear. One day they are chicks, and a few months later they are fully ...
Phys.org / Europe's baked rice bowl seeks escape from drought
Summer came too early to Europe's most important rice-growing region, and weeds are taking over Sharon Angoli's parched paddies in Italy's Pavia province.
Dialog / Bacterial protein reveals a hidden rule for controlling calcium
A small change in acidity can transform the world around us. A squeeze of lemon changes the taste of food. Vinegar preserves vegetables. Stomach acid helps break down a meal. These familiar effects come from protons—tiny ...
Phys.org / When companies face hostile takeover threats, they turn to ESG, and the whole community benefits
When a company faces the prospect of a hostile takeover, its board may reach for traditional anti-takeover defenses. "Poison pills," for instance, allow existing shareholders to buy additional shares at a discount, diluting ...
Phys.org / Planned 1.7 million satellites 'devastating' for astronomy: Study
The 1.7 million satellites that companies are aiming to launch into Earth's orbit in the coming years will have "devastating consequences for astronomy," new research warned Wednesday.
Medical Xpress / A child can drown in seconds. Doctors want more families to be prepared
Doctors and others are sounding an alarm: More U.S. children have been drowning in recent years.
