Phys.org / Ultracold neutrons don't disappear into the mirror world
For decades, a theory in physics has postulated the existence of a mirror world whose interaction with our own reality is extremely feeble. The particles in this mirror universe are also thought to be candidates for dark ...
Medical Xpress / Rat study finds early secondhand smoke exposure can alter tooth enamel mineralization
Exposure to secondhand cigarette smoke during the first days of life can cause changes in tooth enamel mineralization without causing visible changes to the teeth. This was demonstrated in an animal model study conducted ...
Phys.org / Repeating distance patterns let optical systems tackle large optimization problems
From planning transportation networks to organizing massive datasets, many of society's most important challenges boil down to an optimization problem: finding the best solution among an enormous number of possibilities. ...
Tech Xplore / Vacuum attachment designed to improve nuclear fallout collection
In a nondescript Idaho Falls warehouse, a nuclear nonproliferation researcher at Idaho National Laboratory (INL) picks up a small plastic bottle and pours tiny bits of rounded black glass across a worktable.
Tech Xplore / Brain-inspired AI is capable of flexible planning and problem-solving while using far less energy
The capabilities of large AI systems are constantly improving, but they consume a great deal of energy during training and operation. The human brain, by contrast, is extremely energy-efficient: It requires only around 20 ...
Phys.org / Tiny fossils crack a Cretaceous cold case: Ocean acidification triggered one of the ocean's most severe extinctions
A 113-million-year-old marine murder mystery may finally be solved. Using chemical clues locked inside microscopic fossils, Northwestern University scientists found evidence that ocean acidification drove one of the largest ...
Dialog / Bacteria may identify a virus without recognizing its DNA
When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere. The host has the opposite priority: to destroy the virus, ideally before it can do any harm. Biology ...
Phys.org / From single projection to many possibilities: A new tool for climate risk assessment
Assessing how climate change will affect different regions usually requires running a complex chain of models. While this approach provides valuable insights, it is expensive and can cover only a limited set of scenarios ...
Medical Xpress / Forgotten memories can leave silent traces in the brain
Memory is not a perfect record. Some memories fade, while others remain hidden and can be brought back by reminders. But reminders can also distort what is remembered, and scientists still know little about how the brain ...
Medical Xpress / Silver diamine fluoride treatment could halt cavities without shots, drilling or sedation
Every year, untreated tooth decay sends thousands of young U.S. children to emergency departments for dental problems doctors can't treat. Many eventually undergo surgery under general anesthesia, while others endure pain ...
Phys.org / Researchers investigate case of soft-tick borne relapsing fever in Austin area
Researchers at Baylor College of Medicine and the Texas Department of State Health Services have reported a likely case of soft tick-borne relapsing fever (STRF) in an Austin-area resident. Now, they highlight the growing ...
Phys.org / Buried Roman workshop reveals large-scale pottery trade beyond local markets
A few years ago, the first ceramic finds came to light during construction work in the Burg district of the municipality of Hannersdorf. Geomagnetic surveys in subsequent years provided evidence of numerous kilns thought ...
