Brain waves shape the words we hear      (via sciencedaily.com)     Original source 

The timing of our brain waves shapes which words we hear. Researchers used psychophysics, neuroimaging, and computational modeling to test whether neural timing influences perception of more or less frequent speech sounds and words. Neural timing is sensitive to the probability of words vs. sounds in different brain regions, shaping sound and word recognition.

An unlikely hero in evolution: Worms      (via sciencedaily.com)     Original source 

One of Earth's most consequential bursts of biodiversity -- a 30-million-year period of explosive evolutionary changes spawning innumerable new species -- may have the most modest of creatures to thank for the vital stage in life's history: worms.

Ancient medicine blends with modern-day research in new tissue regeneration method      (via sciencedaily.com)     Original source 

For centuries, civilizations have used naturally occurring, inorganic materials for their perceived healing properties. Egyptians thought green copper ore helped eye inflammation, the Chinese used cinnabar for heartburn, and Native Americans used clay to reduce soreness and inflammation. Flash forward to today, and researchers are still discovering ways that inorganic materials can be used for healing. A new article explains that cellular pathways for bone and cartilage formation can be activated in stem cells using inorganic ions. Another recent article explores the usage of mineral-based nanomaterials, specifically 2D nanosilicates, to aid musculoskeletal regeneration.

Could the world famous Roman Baths help scientists counter the challenge of antibiotic resistance?      (via sciencedaily.com)     Original source 

A new study has uncovered a diverse array of microorganisms within the hot waters of the Roman Baths, regularly listed among the UK's most popular tourist attractions. Tests showed 15 of the isolated bacteria -- including examples of Proteobacteria and Firmicutes -- displayed varying levels of inhibition against human pathogens including E.coli, Staphylococcus Aureus and Shigella flexneri.

'Ugly' fossil places extinct saber-toothed cat on Texas coast      (via sciencedaily.com)     Original source 

This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to the fossil that met the eye: a hidden canine tooth that had not yet erupted from the jaw bone. It was just what researchers needed to identify the fossil as belonging to a Homotherium, a genus of large cat that roamed much of the Earth for millions of years.

Scientists develop most sensitive way to observe single molecules      (via sciencedaily.com)     Original source 

A technical achievement marks a significant advance in the burgeoning field of observing individual molecules without the aid of fluorescent labels. While these labels are useful in many applications, they alter molecules in ways that can obscure how they naturally interact with one another. The new label-free method makes the molecules so easy to detect, it is almost as if they had labels.

Scientists invent 'living bioelectronics' that can sense and heal skin      (via sciencedaily.com)     Original source 

Reaserchers have created a prototype for what they call 'living bioelectronics': a combination of living cells, gel, and electronics that can integrate with living tissue. Tests in mice found that the devices could continuously monitor and improve psoriasis-like symptoms, without irritating skin.

New method makes hydrogen from solar power and agricultural waste      (via sciencedaily.com)     Original source 

Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.

Local bright spot among melting glaciers: 2000 km of Antarctic ice-covered coastline has been stable for 85 years      (via sciencedaily.com)     Original source 

A whaler's forgotten aerial photos from 1937 have given researchers the most detailed picture of the ice evolution in East Antarctica to date. The results show that the ice has remained stable and even grown slightly over almost a century, though scientists observe early signs of weakening. The research offers new insights that enhance predictions of ice changes and sea level rise.

Acute sense of touch helps hummingbirds hover near a flower without bumping into it      (via sciencedaily.com)     Original source 

Hummingbird flight mechanics have been well studied but far less is known about how their sense of touch helps them sip nectar from a flower without bumping into it. Most of what scientists know about how touch is processed in the brain comes from studies on mammals, but bird brains are very different from mammal brains. New research shows that touch and air pressure on the wings and legs activate specific clusters of neurons in two regions of the forebrain to create a map of their body, which may help hummingbirds make nuanced adjustments to flight.
