Phys.org / Spiral galaxy's brilliant heart shines bright in a new picture from NASA's Webb telescope
A spiral galaxy's brilliant heart outshines everything within sight in a new picture from NASA's Webb Space Telescope.
Phys.org / No trees, no fans: surviving extreme heat in India's salt pans
India faces challenging heat waves each year, but few places endure conditions as searing as the country's western desert salt pans, where workers rely on simple techniques to survive almost unbearable temperatures.
Phys.org / Medieval jaw reveals Scotland's first known dental bridge made from 20-carat gold
Without good dental care, teeth tend to suffer. An abundance of archaeological evidence has shown that poor oral health was common throughout history. And unsurprisingly, there have been many attempts at dental restoration ...
Medical Xpress / Large study finds a strong link between depression and problem cannabis use
A new meta-analysis of 55 studies involving more than 3 million people has found that 31% of individuals with cannabis use disorder (CUD) also struggle with major depressive disorder (MDD). While a link between these two ...
Phys.org / A persistent quantum computing error finally explained
Scientists have discovered the cause of a persistent glitch that continues to disrupt superconducting quantum computers, even when they have built-in defenses. For all their advanced hardware, superconducting quantum computers ...
Tech Xplore / Silicon oscillators solve computer problems that would take thousands of years using semiconductors
In the era of big data and artificial intelligence, a new approach has emerged for solving combinatorial optimization problems, which involves finding the most efficient solution among many possible options and can otherwise ...
Medical Xpress / Nasal spray developed for prehospital emergency aid for ischemic stroke
A research team from Department of Pharmacology and Pharmacy at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), in collaboration with the InnoHK Advanced Biomedical Instrumentation Centre (ABIC), has developed ...
Phys.org / From flying discs to glowing orbs, these newly opened Pentagon files point somewhere stranger than expected
The Pentagon on Friday released a first batch of secret files documenting reported sightings of unidentified flying objects—some dating back to the 1940s—fanning speculation over whether alien life exists.
Medical Xpress / Head impacts are associated with altered gut microbiome in football players
Non-concussive head impacts—hits to the head that don't cause clinically detectable symptoms—are correlated with subsequent changes to the gut microbiome in a small sample of US collegiate football players, according to a ...
Phys.org / Why are mountain forests in Mexico and Central America hotspots for oak trees? Study shows most definitive answer yet
The mountains of Mexico and Central America harbor some of the greatest biodiversity of oak trees worldwide, and a landmark study conducted by The Morton Arboretum with U.S. and Mexican collaborators provides the most definitive ...
Phys.org / Buried in Arnhem Land, an ancient fire trick may rewrite early stone technology's timeline
A recent archaeological study has identified the earliest lithic heat treatment of chert in the world. Discovered in Australia, this discovery is nearly twice as old as any previously identified chert heat treatment in Eurasia. ...
Phys.org / Scientists split gentoo penguins into four species, one totally new to science
The four-foot-tall Emperor penguin of Antarctica may be the most iconic member of this unique family of birds, but 17 other species of penguins populate the Southern Hemisphere, many of them confined to isolated islands that ...
