New AI noise-canceling headphone technology lets wearers pick which sounds they hear
Most anyone who's used noise-canceling headphones knows that hearing the right noise at the right time can be vital. Someone might want to erase car horns when working indoors, but not when walking along busy streets. Yet people can't choose what sounds their headphones cancel.

Researchers realize water-air acoustic communication based on broadband impedance matching
With increasing demand for exploration and utilization of marine resources, achieving direct and efficient communication between water and air has been an urgent need. Sound waves, as the only propagation way with low attenuation in both water and air, has been considered the most practical way...

Study examines link between underwater landslides and tsunamis
Scientists have calculated a way to determine the speed of past underwater landslides. To do so, researchers from The Ohio State University studied the remains of an underwater landslide just off the coast of Oregon—dubbed the 44-N Slide—that is part of the Cascadia Subduction Zone (CSZ).

A (brief) surprise in study of alcohol, caffeine and sleep
The first known study to look at the combined real-world effects of alcohol and caffeine on nightly sleep quality and quantity came up with an unexpected finding — at first. Researchers at the University of Washington School of Medicine’s Center for the Study of Health and Risk Behaviors and the...

Blame game
Exploring how the human brain takes stock of blame
The human mind does not like to make mistakes—and makes time to avoid repeating them. A new study from University of Iowa researchers shows how the human brain, in just one second, can distinguish between an outcome caused by human error and one in which the person is not directly to blame.

How animals get their stripes and spots
Nature has no shortage of patterns, from spots on leopards to stripes on zebras and hexagons on boxfish. But a full explanation for how these patterns form has remained elusive.

New study using 3D scans of 85% of all known bird species sheds light on extraordinary avian diversity
A new study, using the digitized scans of beaks from over 8,700 bird species, is shedding light on how evolution changes at different scales. While the general principles of evolution by natural selection have been known for over 160 years, the 3D scanning of specimens housed at Natural History...

Model shows how fish synchronize tail fins to save energy
Researchers from Tohoku University have developed a model that simulates the motion of fish tail fins. The model uncovers the underlying mechanisms behind a commonly observed phenomenon in fish: how they synchronize the movement of their tail fins, riding the resultant vortices created, thereby...

The way a sperm tail moves can be explained by mathematics worked out by Alan Turing
Alan Turing might be best know for his work helping to crack Germany's "Enigma" communications code during the second world war. But he also came up with a theory where patterns can form just through chemical compounds spreading out (diffusing) and reacting with one another. This became known as...

Uncertainty abounds in seeding the sky to fight climate change, says study
As greenhouse gas levels increase in Earth's atmosphere, scientists are considering ways to temporarily limit rising temperatures. One idea is to inject aerosols into the stratosphere to reflect incoming sunlight, thereby reducing global warming and its associated risks.

Researchers discover how atmospheric feldspar dust contributes to cloud formation
Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role. Fine powder carried by air influences cloud formation. Water molecules adhere better to feldspar dust than to other particles. Tiny feldspar...

Why do we sleep? Researchers propose an answer to this age-old question
Sleep is a fundamental need, just like food or water. "You'll die without it," said Keith Hengen, an assistant professor of biology at Washington University in St. Louis. But what does sleep actually accomplish? For years, the best researchers could say is that sleep reduces sleepiness—hardly a...

Study shows otters, beavers and other semiaquatic mammals keep clean underwater, thanks to their flexible fur
Underwater surfaces can get grimy as they accumulate dirt, algae and bacteria, a process scientists call "fouling." But furry mammals like beavers and otters that spend most of their lives wet manage to avoid getting their fur slimy. These anti-fouling abilities come, in part, from one of fur's...
