Published 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.
Published Captivating blue-colored ant discovered in India's remote Siang Valley
(via sciencedaily.com)
Original source 
A new species of blue ant was discovered in Yingku village in Arunachal Pradesh, Northeastern India. It was named Paraparatrechina neela, after the word 'neela' which means blue in various Indian languages. Its unique blue coloration makes it stand out among other ant species.
Published Food drove the evolution of giraffes' long neck
(via sciencedaily.com)
Original source 
A study explores body proportions of Masai giraffes, lending insight into why giraffes have such long necks and how this trait might have evolved.
Published How sharks survived a major spike in Earth's temperature
(via sciencedaily.com)
Original source 
The sharks we know today as the open ocean's top predators evolved from stubby bottom dwellers during a dramatic episode of global warming millions of years ago.
Published The unexpected connection between brewing coffee and understanding turbulence
(via sciencedaily.com)
Original source 
Using unconventional statistical mechanics to understand fluid dynamics, a professor helped solve a 150 year old physics problem of how turbulent fluids move through a pipe.
Published 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.
Published 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.
Published 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.
Published The world's most powerful anti-fungal chemistries cause fungal pathogens to self-destruct
(via sciencedaily.com)
Original source 
Scientists have discovered that the most widely-used class of antifungals in the world cause pathogens to self-destruct. The research could help improve ways to protect food security and human lives.
Published Glimpses of a volcanic world: New telescope images of Jupiter's moon Io rival those from spacecraft
(via sciencedaily.com)
Original source 
Combining a new imaging instrument with the powerful adaptive optics capabilities of the Large Binocular Telescope, astronomers have captured a volcanic event on Jupiter's moon Io at a resolution never before achieved with Earth-based observations.
Published '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.
Published 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.
Published 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.
Published NASA's James Webb Space Telescope finds most distant known galaxy
(via sciencedaily.com)
Original source 
Over the last two years, scientists have used NASA's James Webb Space Telescope to explore what astronomers refer to as Cosmic Dawn -- the period in the first few hundred million years after the big bang where the first galaxies were born.
Published Picture this: Snapping photos of our food could be good for us
(via sciencedaily.com)
Original source 
Research reveals taking pictures of food isn't just content for our social media feeds, but could be the key to improving people's diets.
Published Origins of 'Welsh dragons' finally exposed by experts
(via sciencedaily.com)
Original source 
A large fossil discovery has helped shed light on the history of dinosaurs in Wales.
Published 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.
Published Researchers apply quantum computing methods to protein structure prediction
(via sciencedaily.com)
Original source 
Researchers recently published findings that could lay the groundwork for applying quantum computing methods to protein structure prediction.
Published hnRNPM, a guardian of the integrity of cellular protein production
(via sciencedaily.com)
Original source 
Researchers have discovered that the protein hnRNPM prevents the cell from making mistakes while it is producing new proteins, which helps maintain the integrity of this vital process.
Published 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.
