Inside the matrix: Nanoscale patterns revealed within model research organism
Species throughout the animal kingdom feature vital interfaces between the outermost layers of their bodies and the environment. Intricate microscopic structures—featured on the outer skin layers of humans, as one example—are known to assemble in.....»»
The evolutionary timeline of diminished boric acid and urea transportation in aquaporin 10
Aquaporin (Aqp) 10 water channels in humans allow the free passage of water, glycerol, urea, and boric acid across cells. However, Aqp10.2b in pufferfish allows only the passage of water and glycerol and not urea and boric acid......»»
Could dinosaurs be the reason humans can"t live for 200 years?

Study: “Smarter” dogs think more like humans to overcome their biases
Both the shape of a dog's head and cognitive ability determine degree of spatial bias. Enlarge / Look at this very good boy taking a test to determine the origin of his spatial bias for a study on how dogs think. (credit: Eniko K.....»»
Ultra-small, shape-shifting GEMS offer an easier and cheaper way to improve MRI imaging
Microscopic magnetic probes that change shape in response to their environment may greatly enhance magnetic resonance imaging (MRI). However, producing the probes, which are still experimental and have not yet been used in humans, has required access.....»»
Waymo claims autonomy offers ‘significant" safety benefits compared with human drivers
On Wednesday, Waymo researchers unveiled new methods for making meaningful comparisons between the driving performances of humans and autonomous systems......»»
Shipwrecks teem with underwater life, from microbes to sharks
Humans have sailed the world's oceans for thousands of years, but they haven't all reached port. Researchers estimate that there are some three million shipwrecks worldwide, resting in shallow rivers and bays, coastal waters and the deep ocean. Many.....»»
New research models critical climate collapse conditions in ecological and biological systems
As humans continue to drive environmental damage through climate change, predicting points of no return becomes more crucial than ever. Worldwide, humanity and nature alike contend with increases in temperature, drought, wildfires, hurricanes, rising.....»»
Study uncovers major hidden human-driven bird extinctions
Humans have wiped out around 1,400 bird species—twice as many as previously thought—with major implications for the ongoing biodiversity crisis, a new study has found......»»
Scientists discover novel way to attack the trypanosome parasite through its ribosome
Trypanosome is a single-celled parasite that takes an extensive human and economic toll due to its involvement in causing sleeping sickness in humans and a similar disease in cattle. The parasite, found mainly in rural areas of Africa, is transmitted.....»»
How active are the microorganisms in your yogurt? Chemists create a new tool to study probiotic activity

Two possible ways to use black holes as energy source in the distant future
A pair of astrophysicists at Tianjin University, in China, has proposed ways that humans in the distant future might use black holes as an energy source. In their paper published in the journal Physical Review D, Zhan-Feng Mai and Run-Qiu Yang outlin.....»»
New technique could make modeling molecules much easier
Much like the humans that created them, computers find physics hard, but quantum mechanics even harder. But a new technique created by three University of Chicago scientists allows computers to simulate certain challenging quantum mechanical effects.....»»
North America"s first people may have arrived by sea ice highway as early as 24,000 years ago
One of the hottest debates in archaeology is how and when humans first arrived in North America. Archaeologists have traditionally argued that people walked through an ice-free corridor that briefly opened between ice sheets an estimated 13,000 years.....»»

Yes, some cats like to play fetch. It’s science!
Cats play fetch longer, with more retrievals, when they initiate the game. A cat owner throws a tinfoil ball a few feet in front of their expectant cat twice. The cat chases after the tinfoil ball and retrieves it back to the owner b.....»»
