Phys.org / Simplified protein models enable simulations of unknown folding patterns
The chains of amino acids that make up proteins are critical to every form of life. The complex ways that these proteins fold and interact has fascinated researchers for decades. Exactly how a protein folds determines its ...
Phys.org / New technique protects synthetic gene circuits against cell growth dilution
Genetic engineers can design and assemble sophisticated gene circuits to program cells with new functions, but important signaling molecules can become diluted as these cells grow and divide, causing the synthetic gene circuits ...
Phys.org / Unlocking oxygen's hidden role in turning propylene into useful chemicals
A team of researchers has discovered a new way to make valuable industrial chemicals from propylene using a common, low-cost material: lead dioxide (PbO₂).
Phys.org / West Coast mammal-eating killer whales are two distinct communities that rarely mix, finds study
New research has confirmed that West Coast transient killer whales who live between British Columbia and California are two distinct subpopulations: inner and outer coast transients.
Phys.org / A long, bumpy caterpillar-like wormhole may connect two black holes
For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask what the inside should look like if Einstein's theory of gravity and the rules of quantum mechanics ...
Phys.org / Rapa Nui's catastrophic deforestation: Invasive rats, not just humans, may be to blame
Dr. Terry Hunt from the University of Arizona and Dr. Carl Lipo from the University of Birmingham have published a study in the Journal of Archaeological Sciences, reassessing the role of Polynesian rats (Rattus exulans) ...
Phys.org / How quantum computers can aid the search for room-temperature superconductors
For the first time, a quantum computer has successfully measured pairing correlations (quantum signals that show electrons teaming up in pairs), which is essential to helping scientists find one of the holy grails of physics—superconductors ...
Phys.org / Archaeologists examine evidence for Indigenous long-distance voyaging below 50°S
In a study published in the Journal of Coastal and Island Archaeology, Dr. Thomas Leppard and his colleagues, John Cherry and Atholl Anderson, evaluate the evidence for pre-European long-distance voyages below the 50th parallel ...
Phys.org / Scientists map DNA folding at single base-pair resolution in living cells
Scientists from Oxford's Radcliffe Department of Medicine have achieved the most detailed view yet of how DNA folds and functions inside living cells, revealing the physical structures that control when and how genes are ...
Phys.org / Nearby pulsar offers insights into emission physics near the death line
Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), astronomers from the Chinese Academy of Sciences (CAS) and elsewhere have observed a nearby pulsar known as PSR J2129+4119. Results of the observational ...
Phys.org / AI-designed antibodies created from scratch
Research led by the University of Washington reports on an AI-guided method that designs epitope-specific antibodies and confirms atomically precise binding using high-resolution molecular imaging, then strengthens those ...
Phys.org / SXDF-NB1006-2 is a young starburst galaxy experiencing ionized gas outflows, observations find
An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a distant galaxy designated SXDF-NB1006-2. As a result, they found that SXDF-NB1006-2 is a young starburst galaxy that experiences ...
