Researchers discover Earth and space share the same turbulence
In a paper published in Geophysical Research Letters, researchers have discovered that the turbulence in the thermosphere exhibits the same physical laws as the wind in the lower atmosphere. Furthermore, wind in the thermosphere predominantly rotates.....»»
Why the harsh Snowball Earth kick-started our earliest multicellular ancestors
For a billion years, single-celled eukaryotes ruled the planet. Then around 700 million years ago during Snowball Earth—a geologic era when glaciers may have stretched as far as the Equator—a new creature burst into existence: the multicellular o.....»»
Exciting applications for marine degradable, bio- and CO2-based PISOX polymers
Researchers at the Industrial Sustainable Chemistry (ISC) group at the Van 't Hoff Institute for Molecular Sciences have developed a new class of bio- and CO2 based PISOX polymers with surprising properties and applications......»»
Key mechanism of herpesvirus egress uncovered, offering new target for antiviral therapies
An international team of researchers, led by the Leibniz Institute of Virology (LIV), have uncovered crucial details on how herpesviruses exit the cell nucleus without compromising the integrity of the nuclear envelope. Herpesvirus infections are wid.....»»
Researchers create green solvent to boost lignin applications
Lignin, the glue that holds fibers together in trees and plants, is one of the most common yet one of the most complex biocomposites, because there are so many variants and qualities. Its heterogeneous chemical structure makes it difficult to investi.....»»
Wind tunnel study shows hypersonic jet engine flow can be controlled optically
What if the future of space travel were to look less like Space-X's rocket-based Starship and more like NASA's "Hyper-X," the hypersonic jet plane that, 20 years ago this year, flew faster than any other aircraft before or since?.....»»
Visual explanations of machine learning models to estimate charge states in quantum dots
A group of researchers has successfully demonstrated automatic charge state recognition in quantum dot devices using machine learning techniques, representing a significant step toward automating the preparation and tuning of quantum bits (qubits) fo.....»»
Aging-emulating biosystem derived from hTSCs
A research team from the Center for Translational Stem Cell Biology (CTSCB) under the LKS Faculty of Medicine at the University of Hong Kong (HKUMed) has developed the world's first cellular system that can be used to rapidly discover molecules for a.....»»
NASA picks SpaceX to carry ISS to its watery graveyard after 2030
NASA on Tuesday said it had picked SpaceX to build a vessel to carry the International Space Station back through Earth's atmosphere and on to a final resting place in the Pacific Ocean after it is retired in 2030......»»
"Power rivalry in space": China lunar mission fuels US misinformation
A historic lunar mission has demonstrated China's growing scientific prowess, but the feat has set off a torrent of misinformation targeting the United States that researchers say reflects their bitter competition in space......»»
SpaceX will help to crash the International Space Station
The space station faces a dramatic end when it ends operations in about six years from now, and SpaceX will help to make it happen......»»
Researchers just solved AI’s biggest conundrum
That's roughly the draw of a 100W light bulb, and a 50x improvement over the 700W that an NVIDIA H100 GPU consumes......»»
Looking for atmospheres in the ultimate quest for extraterrestrial life
To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba has used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his.....»»
Researchers find genetic stability in a long-term Panamanian hybrid zone of manakins
We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stabl.....»»
Researchers built AI models that use less power than a light bulb
That's roughly the draw of a 100W light bulb, and a 50x improvement over the 700W that an NVIDIA H100 GPU consumes......»»
Canceled Geoengineering Experiment to Block the Sun Won’t Stop Rich Donors from Trying
A botched geoengineering experiment to limit the amount of sunlight hitting Earth hasn’t dimmed donors’ enthusiasm for funding the research.....»»
The Paris Olympics Face Bacterial Challenges, and Microplastics Are Found in Penis Tissues
Microplastics are everywhere, Olympic ambitions for the Seine River are complicated by poop, and the Starliner spacecraft delays its return to Earth......»»
