Phys.org / Quantum-level effects in biology: Weak magnetic fields and isotopes can alter cell protein structures
A novel method to manipulate the inner structure of cells connects several scientific fields and could represent a significant step in the treatment of neurodegenerative diseases, such as Alzheimer's and Parkinson's disease. ...
Phys.org / Rewriting our understanding of early hominin dispersal from Africa to Eurasia
What if Homo erectus (H. erectus), the direct ancestor of modern humans, arrived in China much earlier than we thought? Research published in Science Advances may rewrite our understanding of early human dispersal in that ...
Phys.org / New 'Mars GPS' lets Perseverance pinpoint its location within 25 centimeters
Imagine you're all alone, driving along in a rocky, unforgiving desert with no roads, no map, no GPS, and no more than one phone call a day for someone to inform you exactly where you are. That's what NASA's Perseverance ...
Phys.org / Pekingese, Shih Tzu and Staffordshire bull terrier among 12 dog breeds at risk of serious breathing condition
Scientists have identified a further 12 dog breeds as being at risk of brachycephalic obstructive airway syndrome—a condition that can cause serious breathing problems—including the Pekingese, Shih Tzu, Boston terrier, ...
Phys.org / Trapping a single protein in a molecular cage: A new path to drug discovery for amyotrophic lateral sclerosis
Proteins often function in pairs or groups, concealing their internal connection points and making it difficult for scientists to study their individual units without altering their natural structure. In a study published ...
Phys.org / Simulations map how single-crystal battery materials could boost cycle life
The performance of rechargeable batteries is governed by processes deep within their components. A fundamental understanding of electrochemistry, structure–property–performance relationships and the effects of processing ...
Phys.org / Microscopic mirrors for future quantum networks: A new way to make high-performance optical resonators
Researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Faculty of Arts and Sciences have devised a new way to make some of the smallest, smoothest mirrors ever created for controlling ...
Phys.org / Rising simultaneous wildfire risk compromises international firefighting efforts
The most high-risk conditions for fires are increasingly happening across countries at the same time, making resulting wildfires even more challenging to tackle, new research reveals.
Phys.org / Chiral myosin steers actin into stable rotating rings without a template, study finds
Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan. Instead, order emerges on its own from countless interactions between molecules that are constantly ...
Phys.org / Why negativity can motivate founders: Study links doubts to greater persistence
A new study finds entrepreneurs become more committed to their business ventures when they are told they will fail, increasing their efforts to make those businesses successful. "Most entrepreneurs—people who start their ...
Phys.org / Chitosan-nickel biomaterial becomes stronger when wet, and could replace plastics
A new study led by the Institute for Bioengineering of Catalonia (IBEC) has unveiled the first biomaterial that is not only waterproof but actually becomes stronger in contact with water. The material is produced by the incorporation ...
Phys.org / The Princess of Bagicz: Dendrochronology settles debate over age of rare Roman-era wooden coffin
Dr. Marta Chmiel-Chrzanowska and her colleagues conducted a multidisciplinary analysis of the only known preserved wooden coffin from the Roman Iron Age, the Princess of Bagicz. The study, published in Archaeometry, used ...
