Phys.org / Carbon emissions now more than double the planetary boundary, analysis finds
Earth is not infinite. Pollution beyond certain levels threatens the climate and ecosystems. To prevent this, scientists have proposed planetary boundaries, defining the safe operating limits of the Earth system. A KAIST ...
Phys.org / Nocturnal ants use lunar compass and sophisticated calculations to travel at night
It's well known that many animals, including migratory birds, butterflies, and even fish, use the sun for navigational purposes. Nocturnal animals are dealt a more difficult hand, however, as the moon's path is far more variable. ...
Medical Xpress / Combining exercise and sleep coaching can help improve sleep and health markers in young women
Instances of insomnia are on the rise globally, which is a matter of great concern, as lack of sleep can take a heavy toll on one's physical and mental health. A recent study by The Education University of Hong Kong investigated ...
Phys.org / Astronomers collect rare evidence of two planets colliding
Anastasios (Andy) Tzanidakis was combing through old telescope data from 2020 when he found an otherwise boring star acting very strangely. The star, named Gaia20ehk, was about 11,000 light-years from Earth near the constellation ...
Phys.org / Japanese scientists discover how falling cats almost always make perfect landings
When cats fall, they usually land on their feet. This uncanny ability to right themselves before hitting the ground has long puzzled scientists. Now, a team from Yamaguchi University in Japan has the answer, and it's all ...
Phys.org / Hydrogen atmosphere could keep exomoons habitable for billions of years
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck ...
Phys.org / Flash heating upcycles waste glass into SiC nanowires in seconds
Engineering silicon carbide (SiC) with tailored morphologies for electronics and structural reinforcement materials has always been a costly and time-consuming affair, but scientists can now do it in a flash. A new study ...
Phys.org / Centuries of net-negative emissions are required to secure a safe climate future, two studies suggest
Two new studies conclude that stabilizing long-term climate risks will require sustained net-negative carbon dioxide (CO₂) emissions for centuries. Approaching the problem from distinct perspectives—legal and technological ...
Tech Xplore / Hybrid 'super foam' uses 3D-printed struts to absorb up to 10 times more energy
Aerospace engineering and materials science researchers at Texas A&M University and the DEVCOM Army Research Laboratory have developed a "super foam" that can absorb up to 10 times more energy than conventional padding.
Phys.org / DNA origami vaccine rivals mRNA shots while being easier to store and manufacture
The COVID-19 pandemic brought messenger RNA (mRNA) vaccines to the forefront of global health care. After their clinical trial stages, the first COVID-19 mRNA vaccine was administered on 8 December 2020 and mathematical models ...
Phys.org / Highlighting the hidden climate cost of the Israel–Gaza war
A new study estimates that the Israel–Gaza war has generated around 33 million metric tons of carbon dioxide equivalent (CO2e), highlighting the often-overlooked environmental impact of armed conflict.
Phys.org / Researchers use AI to develop RNA-based synthetic NAND switch in living cells
An interdisciplinary research team from two working groups at the Center for Synthetic Biology at TU Darmstadt has developed the first RNA-based genetic switch that precisely replicates the logical behavior of a NAND gate, ...
