Some solitary mammals have surprisingly social lives: What one researcher has learned from a tiny south African rodent
We probably all know someone who lives a solitary life. But not everyone realizes that there are solitary individuals in the animal kingdom, too. Examples of solitary species are some shrews, and large predators, such as black bears (Ursus americanus.....»»
Why cricket’s latest bowling technique is so effective against batters
Wind tunnel experiments show how the ball's transverse spin impacts pressure fields. Enlarge / Some cricket bowlers favor keeping the arm horizontal during delivery, the better to trick the batsmen. (credit: Rae Allen/CC BY 2.0).....»»
AI-driven method enhances electron microscopy imaging capabilities of complex biological systems
Electron microscopy has enabled visualization of the intricate details inside cells. The advancement to 3D electron microscopy, known as volume EM (vEM), has further expanded this three-dimensional, nanoscale imaging capacity. However, trade-offs bet.....»»
Cricket physics: Wind tunnel experiments reveal why bowling with a near horizontal arm makes for tough batting
Key to winning a cricket match is tricking the other team's batters—no small feat, as bowlers bowl cricket balls nearly 100 miles per hour. In recent years, a bowling technique that has become popular involves keeping the arm almost entirely horizo.....»»
"Rare species" not seen in the area for 50 years spotted on Arizona trail camera
To ensure her trail cameras would stay operational during the hot Arizona summer, researcher Kinley Ragan trekked to 23 of them......»»
Neutrons reveal the existence of local symmetry breaking in a Weyl semimetal
The first materials scientists might have been early humans who—through trial-and-error experiments—discovered the first "cutting-edge" technologies. They found that the best arrowheads and other tools could be made from certain types of natural,.....»»
The Physics of Cold Water May Have Jump-Started Complex Life
When seawater gets cold, it gets viscous. This fact could explain how single-celled ocean creatures became multicellular when the planet was frozen during “Snowball Earth,” according to experiments......»»
People game AIs via game theory
They reject more of the AI's offers, probably to get it to be more generous. Enlarge / In the experiments, people had to judge what constituted a fair monetary offer. (credit: manusapon kasosod) In many cases, AIs are tr.....»»
Free ChatGPT users can now generate images with DALL-E 3 (just)
ChatGPT was originally limited to text interactions, but paid subscribers last year gained the ability to use the chatbot to generate images with DALL-E 3. That feature is now coming to free ChatGPT users too, though you’ll be limited to just tw.....»»
Study shows people associate kindness with religious belief
Experiments conducted by UC Merced researchers find that people who perform good deeds are far more likely to be thought of as religious believers than atheists. Moreover, the psychological bias linking kindness and helpfulness with faith appears to.....»»
“Perfect” Windows downgrade attack turns fixed vulnerabilities into zero-days
A researcher has developed a downgrade attack that can make Windows machines covertly, persistently and irreversibly vulnerable, even if they were fully patched before that. A downgrade attack exploiting the Windows Update process The direction of Sa.....»»
The link between fuzzy images and quantum fields
Mathematical solutions to thorny quantum problems can be found more quickly by exploiting the correspondence between the statistical methods used in deep learning and techniques for implementing quantum simulations, a team led by a RIKEN researcher h.....»»
Research confirms importance of symmetry in pre-ignition fusion experiments
Researchers at Lawrence Livermore National Laboratory (LLNL) have retrospectively confirmed that implosion asymmetry was a major aspect of fusion experiments before achieving ignition for the first time at the Lab's National Ignition Facility (NIF),.....»»
Lasers deliver powerful shocking punch in material experiments
Shock experiments are widely used to understand the mechanical and electronic properties of matter under extreme conditions, like planetary impacts by meteorites. However, after the shock occurs, a clear description of the post-shock thermal state an.....»»
Observations confirm plasma bubble origin of persistent radio emissions from fast radio bursts
Fast Radio Bursts (FRBs) are one of the most recent open mysteries of modern astrophysics. Within a few milliseconds, these powerful events release an immense amount of energy, among the highest observable in cosmic phenomena......»»
Machine learning leads to first regional scale forest mapping using 1-meter measurements
An Arkansas researcher has developed the first high-resolution forest canopy cover dataset for an entire state, providing valuable insights for forest management and conservation to a major economic sector in Arkansas......»»
Scientists discover highest-energy gamma-ray line in the universe
A research group led by the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS) report the discovery of a gamma-ray line up to 37 million electron-volts from an extremely bright gamma-ray burst, which represents the highe.....»»
Ultrafast electron microscopy technique advances understanding of processes applicable to brain-like computing
Today's supercomputers consume vast amounts of energy, equivalent to the power usage of thousands of homes. In response, researchers are developing a more energy-efficient form of next-generation supercomputing that leverages artificial neural networ.....»»
The Higgs particle could have ended the universe by now—here"s why we"re still here
