Phys.org / EV-SELEX speeds GPCR drug discovery by capturing receptor-bound DNA aptamers
G protein-coupled receptors (GPCRs) are the most abundantly expressed proteins in the human body, regulating diverse physiological processes ranging from pain perception to hormone signaling. Owing to their central roles ...
Phys.org / How proximity steals energy from nanoresonators
Nanomechanical resonators are miniature vibrating structures on chips that oscillate at frequencies ranging from a few kilohertz to gigahertz. They are used as ultrasensitive detectors of mass and force, temperature and pressure, ...
Phys.org / New biobased polymers exhibit excellent tensile properties beyond polyolefins
The research group of Professor Kotohiro Nomura, Tokyo Metropolitan University, in cooperation with the research groups of Senior Researcher Hiroshi Hirano and Director Seiji Higashi of the Osaka Research Institute of Industrial ...
Phys.org / Cave finds reveal modern humans and Neanderthals may have shared long-term cultural continuity
Tens of thousands of years ago, Homo sapiens coexisted with Neanderthals, Homo neanderthalensis. Many of us living today carry a small amount of Neanderthal DNA, indicating that the two species may have shared much more than ...
Phys.org / Early parenting shapes the brain and socio-sexual behavior, rodent study shows
Past psychology studies have consistently highlighted the importance of social bonds for survival, showing that enduring relationships are linked with a longer life expectancy, a more resilient immune system, better cardiovascular ...
Phys.org / First synthetic protein motor moves along DNA in controlled, programmable steps
Researchers from UNSW Sydney have built the first artificial protein motor capable of taking controlled, directional steps along a DNA track. The protein, dubbed Tumbleweed, moves by alternating between three "feet" that ...
Phys.org / Traces of Earth's primordial magma ocean discovered in lava from a modern volcanic eruption
In May 2018, the island of Mayotte, between Madagascar and Mozambique, began to experience a series of earthquakes that led to the discovery of an underwater volcano, now called Fani Maoré. Multiple scientific expeditions ...
Phys.org / Ancient hobbit-like humans may have survived on meat left behind by Komodo dragons
Arguably one of the most curious ancient human relatives is Homo floresiensis, a 3-foot-tall species that lived on the Indonesian island of Flores and has been nicknamed "hobbit" for its diminutive stature. Even though they ...
Phys.org / Chemists capture structure of the elusive borylnitrene trapped in a crystal using X-ray
Nitrenes are the ghosts of synthetic chemistry, formed in an instant and gone just as quickly, rearranging into something entirely different. These highly reactive intermediates are widely used in synthesis, yet remain notoriously ...
Phys.org / Phylogenomics reveals angel insects' ancestry, resolving century‑old 'Zoraptera problem'
Zoraptera, also known as angel insects or ground lice, are tiny termite-like insects generally found underneath bark or in decaying wood. The Zoraptera group includes a few dozen known insect species that closely resemble ...
Phys.org / AI system translates protein sequences into text, helping reveal functions of unknown proteins
In a paper published in Proceedings of the National Academy of Sciences, researchers from Technion and Tel Aviv University present BetaDescribe, an AI system that translates protein sequences into natural-language descriptions, ...
Phys.org / Bioinspired strategy creates complex 3D curved structures via programmed shrinkage
The shape of biological structures, ranging from flower petals to the limbs or organs of animals, is often naturally best suited for performing specific functions. Biological structures also often present curved surfaces ...
