Phys.org / Failed supernova provides clearest view yet of a star collapsing into a black hole
Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's transformation into a black ...
Phys.org / Scientists uncover Iron Age origins of Vietnamese tooth blackening practices
Not everyone wants their teeth to be white and gleaming. Tooth blackening is a recognized part of modern Vietnamese culture, and a recent discovery hints that the roots of this practice may stretch all the way back to the ...
Phys.org / Only humans have chins: Study shows it's an evolutionary accident
Dashiell Hammett mentioned Sam Spade's jutting chin in the opening sentence of his novel, "The Maltese Falcon." Spade's chin was among the facial features Hammett used to describe his fictional detective's appearance, but ...
Phys.org / Scent analysis reveals the composition of ancient Egyptian embalming materials
In a recent study published in the Journal of Archaeological Science, Wanyue Zhao and her colleagues used volatile organic compounds (VOCs) to analyze the composition of scents given off by mummies and their embalming materials. ...
Tech Xplore / Atom-thin ferroelectric transistor can store 3,024 polarization states
Over the past few decades, electronics engineers have been trying to develop new neuromorphic hardware, systems that mirror the organization of neurons in the human brain. These systems could run artificial intelligence (AI) ...
Phys.org / Porous material uses green and blue light to repeatedly store and release CO₂
Scientists at the University of Groningen, led by Nobel laureate Ben Feringa and colleagues, have created a new porous material that captures and releases carbon dioxide using only visible light. The breakthrough could pave ...
Phys.org / Time crystals could become accurate and efficient timekeepers
Time crystals could one day provide a reliable foundation for ultra-precise quantum clocks, new mathematical analysis has revealed. Published in Physical Review Letters, the research was led by Ludmila Viotti at the Abdus ...
Phys.org / Antarctic ice melt can change global ocean circulation, sediment cores suggest
A new study shows that during the last two deglaciations, i.e., the transition from an ice age to the warm interglacial periods, meltwater from the Antarctic ice sheet intensified stratification in the Southern Ocean. The ...
Medical Xpress / Therapeutic outcomes for autistic adults: Exploring factors that shape anxiety and depression trajectories
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by differences in social interactions and in the understanding of others' thoughts or feelings, restricted interests and repetitive behaviors. ASD can ...
Phys.org / How Indigenous ideas about nonlinear time can help us navigate ecological crises
It is common to think of time as moving in only one direction—from point A, through point B, to point C.
Phys.org / Arctic peatlands are expanding as temperatures continue to rise, new research confirms
The Arctic is warming faster than the rest of the planet, with average temperatures increasing by about 4°C in the last four decades. A new study, led by the University of Exeter, shows peatlands have expanded since 1950, ...
Medical Xpress / Common anti-seizure drug prevents Alzheimer's plaques from forming, study shows
While physicians and scientists have long known that Alzheimer's disease involves the buildup of toxic protein fragments in the brain, they have struggled to understand how these harmful fragments are produced. Now, in a ...
