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.

Paving the way for hydrogen from algae enzymes      (via sciencedaily.com)     Original source 

Under certain conditions, some algae are able to produce hydrogen -- a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present. Researchers have identified how such a cofactor, the so-called hydrogen cluster, is assembled. Specifically, they describe the previously unexplained role of the enzyme HydF, which is involved in the final steps of assembly.

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.

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.

New, modified CRISPR protein can fit inside virus used for gene therapy      (via sciencedaily.com)     Original source 

Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells.

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.

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.

Editing without 'cutting': Molecular mechanisms of new gene-editing tool revealed      (via sciencedaily.com)     Original source 

New research has determined the spatial structure of various processes of a novel gene-editing tool called 'prime editor.' Functional analysis based on these structures also revealed how a 'prime editor' could achieve reverse transcription, synthesizing DNA from RNA, without 'cutting' both strands of the double helix. Clarifying these molecular mechanisms contributes greatly to designing gene-editing tools accurate enough for gene therapy treatments.
