Rare goblin shark filmed alive for the first time in the deep sea
Rare goblin shark filmed alive for the first time in the deep sea
For the first time, researchers have filmed the elusive goblin shark alive in the deep ocean where it naturally lives. The remarkable sightings greatly expand the shark's known range and depth, showing that this 125-million-year-old "living fossil" still has plenty of secrets lef
New probe could help trace Alzheimer's-linked lipids one cell at a time
Cells sitting side by side in the same tissues are not identical. Each cell carries its own subtly different chemical signature—a hidden individuality that can reveal how diseases take root and spread. Now, researchers from the University of Osaka have developed a technique sensi
The Ozempic and Wegovy mistake sending thousands to poison control
The Ozempic and Wegovy mistake sending thousands to poison control
Poison control calls involving semaglutide (Ozempic and Wegovy) soared after the drug was approved for weight management, with researchers linking the increase to accidental dosing mistakes rather than intentional misuse. Simple education about proper weekly dosing and gradual do
Scientists finally solved a 150-year-old gallium mystery
Scientists finally solved a 150-year-old gallium mystery
Scientists have rewritten the story of gallium after discovering that its unusual atomic bonds re-form at high temperatures, contradicting decades of accepted theory. The finding changes how researchers explain why the metal melts so easily and behaves unlike almost any other met
Uncovering the secrets of the basking shark's bizarre skin
New research reveals the unusual shape, size and pattern of the dermal denticles that cover basking sharks—thought to be unique to this species. Researchers propose that the shape and arrangement of the skin's scales protect the skin while also allowing for the stretchiness requi
Researchers develop low-cost AI tool to help cities map urban tree canopy
Researchers develop low-cost AI tool to help cities map urban tree canopy
As a heat dome drives dangerous temperatures across much of the United States and renews concerns about extreme heat, USC researchers have developed a new, freely available AI tool that could help cities better understand one of their best defenses against rising temperatures: tr
Experimental bathtub: the remote lake island trying wave power to boost energy security
Researchers on Beaver Island, in Lake Michigan, are trying to find a more reliable form of power using local resourcesBeaver Island sits in the middle of the northernmost end of Lake Michigan, about 70 miles from the maritime border with Canada. The forested island, just a little
Transparent nanosheets could shrink phone cameras while preserving high-resolution color i
Researchers at Nagoya University in Japan have developed gallium-doped zinc oxide (GZO) nanosheets that may enhance camera resolution in compact devices, including smartphones and medical endoscopes.
Unraveling the glass-like nature of epithelial tissues
In a new study, researchers at the Indian Institute of Science (IISc) have resolved a longstanding mystery by showing how epithelial tissues exhibit slow-moving, glass-like behavior despite their fast-paced biological activity. Their study is published in the journal Nature Commu
New technique takes the heat out of 3D printing process
New technique takes the heat out of 3D printing process
Researchers have developed a new 3D printing technique that allows the printing of whole objects while controlling the temperature of the chemical reaction to stabilize the process. Academics in the University of Nottingham's Faculty of Engineering, in collaboration with the Univ
Study questions growing international trade in critically endangered sand tiger sharks
Study questions growing international trade in critically endangered sand tiger sharks
In a new study led by University of Delaware researchers Aaron Carlisle and Ed Hale, researchers point to concerns in the international trade of sand tiger sharks, a critically endangered shark species globally, for display in aquariums. The work is published in the journal Front
Mouse found near 7,000 meters may rewrite limits of mammal survival
A tiny mouse living nearly 7,000 meters (23,000 feet) above sea level in the Andes is helping scientists rethink the limits of life on Earth. The animal, a leaf-eared mouse, is the focus of a new international study co-authored by McMaster University researchers, revealing how ma
