Phys.org / Black hole star: Astronomers discover a brand-new type of astrophysical object
Astronomers at MIT and elsewhere have spotted an extremely bright red spot in the early universe. The object resembles an enormous star, roughly the size of our solar system. But it also is putting out 100 billion times more ...
Phys.org / Male Neanderthal pelvises resemble those of modern females, challenging decades-old assumptions
A new study by the Department of Anatomy and Anthropology at Tel Aviv University, published in Scientific Reports, offers an explanation for one of the striking differences between men and women: the evolutionary development ...
Phys.org / Early-universe plasma may have stopped dark photons from heating cosmos
A new paper published in Physical Review Letters reveals that a leading dark matter candidate—the hypothetical "dark photon"—would not have heated the early universe as previously thought. The finding opens a vast region ...
Tech Xplore / Why the data behind a part now matters as much as the part itself
Counterfeit and out-of-spec components are entering U.S. defense supply chains through thousands of small and midsized suppliers that make up the lower tiers of the industrial base. Researchers at the Georgia Tech Manufacturing ...
Phys.org / How body size and habitat shape the vocal repertoires of primates
Biologists, zoologists and psychologists have been trying to trace the origins of human language for centuries. One well-known theory, known as the social brain hypothesis, suggests that increasingly complex social lives ...
Phys.org / AI agents coordinate behavior based on majority opinion—even when said opinions are meaningless
A new study published in Science Advances takes a closer look at how AI agents' choices are influenced by their peers. The team found that more advanced models tend to follow the majority when shown other agents' choices, ...
Medical Xpress / Smart delivery systems could make noninvasive nasal routes to the brain possible
A protective layer that is extremely picky about not letting harmful substances in can sometimes also keep useful things from entering the very space it is meant to protect. The body's blood-brain barrier (BBB) is one such ...
Medical Xpress / Common arthritis pill repurposed to boost hair regrowth in alopecia patients
Upadacitinib is a medication widely used for the treatment of rheumatoid arthritis that works by inhibiting Janus kinase (JAK) enzymes, which are involved in signaling pathways that regulate immune responses. Now, scientists ...
Phys.org / Molecular memory: How a mother's age echoes in her offspring's cells
In humans and many other animals, a mother's age can affect the physical and behavioral characteristics of the next generation. Scientists call these changes maternal age effects, and while they are widespread across the ...
Medical Xpress / Emotion-regulation training reduces distress and changes the brain, team reports
A five-week training intervention taught college students to better regulate their emotions in response to negative events, a new study finds. After the training, the students reported less emotional distress when viewing ...
Medical Xpress / Experimental pill targets nerve pain pathway, cutting opioid use after abdominal surgery
Opioids can be highly effective at relieving moderate to severe pain, whether it comes from surgery, an injury or conditions such as cancer. They work by activating opioid receptors in the brain and body, which block pain ...
Medical Xpress / States enact emergency orders on kratom while awaiting federal rules
