Phys.org / Parasitic plants act like genetic engineers by stealing and remodeling useful genes

Many plant species parasitize other plants by latching on and taking the nutrients their hosts need to survive. But sometimes, plants steal more than nutrients; they take genes.

Phys.org / Oxygen collisions reveal how quark–gluon matter approaches equilibrium

High-energy nuclear collisions recreate extreme conditions similar to those in the early universe, producing quark–gluon plasma (QGP), a hot state of matter in which quarks and gluons are no longer confined inside protons ...

Phys.org / AI model designs potentially stable protein sequences beyond those found in nature

A protein's function is determined by its structure, and structure—the way a protein folds—is determined by its sequence of amino acids, the building blocks of proteins.

Phys.org / Emperor penguin colonies reveal decades-long resilience and flexible breeding sites

With their charming waddles, heat-conserving huddles and tuxedo-like plumage, emperor penguins are among the world's most recognizable animals. Recent satellite surveys estimate that hundreds of thousands of the flightless ...

Phys.org / Shear flow in narrow channels sparks amyloid formation, experiments reveal

Many cars and not enough lanes is a recipe for traffic jams. Now, researchers from Japan show that even proteins can get backed up and start behaving poorly when too many try to squeeze too quickly through a small space.

Phys.org / Heat-tolerant corals may be more vulnerable to disease

Corals that partner with heat-tolerant algae may be better equipped to survive warming oceans—but that resilience comes with an unexpected trade-off, according to a new study from Boston University published in Science Advances.
