Phys.org / Engineering the bite of ancient marine predators
An international team of researchers, led by paleontologists of the University of Liège, has investigated the biting capabilities of extinct predatory marine reptiles, revealing how these formidable predators could coexist ...
Phys.org / Seed banks may complicate gene drives aimed at controlling weeds
Gene drives—a genetic engineering approach that quickly spreads specific genetic changes throughout a population, whether to kill it off or add a new trait—may have potential for controlling weeds. But so far, gene drives ...
Phys.org / 3D root model captures mangroves' capacity to protect coastal communities from storm waves
Mangrove forests are natural wonders that protect coastal areas, particularly in tropical and subtropical regions. They are able to dissipate wave energy and limit flooding, which can even mitigate tsunamis and coastal inundations ...
Phys.org / Domino polymerization provides a new route to versatile, degradable plastics
Plastic, once ingenious for its durability and versatility, has become a global environmental issue that is affecting every aspect of life. This, in turn, is fueling the development of degradable polymers as alternative solutions. ...
Phys.org / Nanotube injector transfers cytoplasmic contents and organelles between living cells safely
Cells are not isolated units; they continuously exchange proteins, genetic material, and even entire organelles with their neighbors. Intercellular transfer influences how tissues develop, respond to stress, and repair damage. ...
Phys.org / Bumblebees can perceive rhythm, despite their brains being the size of a sesame seed
Humans are creatures of rhythms. As far as we know, humans have always sung and always danced. We can recognize a song by its rhythm alone, regardless of whether it is played fast or slow.
Phys.org / Bacterial enzyme uses a donut-shaped ring to shred tough collagen, study reveals
Collagen is an important protein that helps build the tissues of humans and animals. It is very strong because it is made of three protein strands twisted tightly together like a rope. Because of this sturdy structure, ordinary ...
Phys.org / Artemis II astronauts rocket toward the moon after spending a day around Earth
NASA's Artemis II astronauts fired their engines and blazed toward the moon Thursday night, breaking free of the chains that have trapped humanity in shallow laps around Earth in the decades since Apollo.
Phys.org / Real-time nanoscale measurements map reduction and oxidation in solar-fuel reactions
Solar-power photocatalysis—turning sunlight into energy—holds promise for sustainable and cost-efficient energy and chemical production. Advancing the technology, though, has been hindered by a lack of understanding of exactly ...
Phys.org / Cosmologists collaborate to sharpen measurements of the Hubble constant
Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in Astronomy & Astrophysics, ...
Phys.org / Ytterbium atomic clock could open a new window on fundamental physics
For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and extremely sensitive to ...
Phys.org / Gravity from positivity: Single massive spin-3/2 particle makes gravity logically inevitable, study claims
Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles ...
