Phys.org / Naked photobombing comet found in public image
Sometimes images are released before anyone realizes they have been photobombed, meaning something unexpected showed up in the background. A team of researchers found a naked photobombing comet in publicly available archival ...
Phys.org / How chromosomes find their partners
For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit flies that these repetitive sections of genetic material act as a kind of barcode, enabling the correct ...
Phys.org / NASA Johnson pilots chase moon's shadow for eclipse science
During the Aug. 12 total solar eclipse over Europe, scientists aimed to study a long-standing mystery: why the sun's outer atmosphere, the corona, is far hotter than its visible surface. Capturing the data they needed meant ...
Medical Xpress / Study finds gaps in home rehab after joint replacement
Every year, hundreds of thousands of older Americans recover from hip and knee replacement surgery at home. For many, that recovery depends on timely access to physical or occupational therapy after leaving the hospital.
Tech Xplore / New system recognizes masked faces using eyes and forehead
A face-recognition system that can identify people even if they are wearing a face mask covering their nose and mouth is discussed in the International Journal of Computational Vision and Robotics. The new system uses biometrics ...
Phys.org / 3D atomic imaging reveals a new pathway to crystal formation
The most common scientific approach for thinking about how condensation, freezing and other phase transitions begin is based in classical nucleation theory, which was developed about a century ago. Thousands of experiments ...
Phys.org / Adaptation and a 'Noah's Ark for trees' offer hope for endangered black ash
With the invasive emerald ash borer beetle decimating black ash across North America, according to the U.S. Forest Service, a team led by researchers at Penn State conducted an expansive study of genetic diversity in black ...
Medical Xpress / Doctors and scientists race to understand a rising form of heart failure
Approximately 3 million people in the United States are living with a condition called heart failure with preserved ejection fraction, or HFpEF. The number of people with this form of heart failure, which is more common in ...
Tech Xplore / Major security weaknesses found in leading open-weight LLMs
Safety protections built into some of the world's most widely used artificial intelligence (AI) models can be stripped away with alarming ease, according to a new international study.
Tech Xplore / Cartilage-inspired lithium battery coating cushions cathodes against cracks during repeated charging
Lithium-ion batteries (LiBs) power electric vehicles and most existing electronics, ranging from laptops to smartphones, tablets, smart appliances and wearable devices. These batteries charge and discharge by moving lithium ...
Phys.org / Molecular trick opens the door to a new generation of glass
Researchers at TU Dortmund University, Paderborn University, the University of Duisburg-Essen, and the University of Oxford have developed a new method for selectively modifying the internal structure of specific types of ...
Phys.org / Scientists resurrect ancient proteins, offering new antibiotic leads
University of Oregon biologists have resurrected prehistoric proteins up to 160 million years old that carry natural antimicrobial properties. The revived molecules could inspire the design of new treatments for antibiotic-resistant ...
