Phys.org / Deep-sea natural compound targets cancer cells through a dual mechanism
A collaborative research team has uncovered a previously unknown mechanism of action of yaku'amide B, a structurally complex peptidic natural product derived from deep-sea sponge found in the waters near Yakushima Island, ...
Phys.org / Quantum computers must overcome major technical hurdles before tackling quantum chemistry problems
Although the potential applications of quantum computing are widespread, a new feasibility study suggests quantum computers still face major hurdles in solving quantum chemistry problems. The study, published in Physical ...
Phys.org / Galactic islands of tranquility: 'Little red dots' may have brewed life's building blocks
Astronomers have found that both the core of our Milky Way and the earliest proto-galaxies in the universe share a surprising trait: They are unusually calm and quiet in terms of harsh radiation. This tranquility is not just ...
Phys.org / Astronomers capture birth of a magnetar, confirming link to some of universe's brightest exploding stars
Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the cosmos. The finding ...
Phys.org / Ancient Filipino skeleton reveals a rare hip condition further complicated by scurvy
The growing paleopathological literature shows that scurvy was not a rare problem among people living in the ancient Asia-Pacific tropics. Scurvy is increasingly identified throughout the region, primarily in children but ...
Phys.org / Scientists confirm existence of molecule long believed to occur in oxidation
In the journal Science Advances, scientists in Sweden and the U.S. report the first-ever direct observation of a type of short-lived molecule that has shaped decades of thinking in atmospheric chemistry, combustion research ...
Phys.org / Huge dinosaur bone may reveal the origins of T. rex
Tyrannosaurus rex is one of the most recognizable names of the dinosaur world, a hulking and terrifying meat-eating behemoth. While fossil remains have been extensively studied, not much is known about its family history ...
Phys.org / New microscope offers sharper view into momentum space
Electrons are tiny and constantly in motion. How they behave in a crystal lattice determines key material properties: electrical conductivity, magnetism, or novel quantum effects. Anyone aiming to develop the information ...
Tech Xplore / A bicycle robot that can drive fast and jump over obstacles
Experienced human cyclists can perform a wide range of maneuvers and acrobatics while riding their bicycle, from balancing in place to riding on a single wheel or hopping over obstacles. Reproducing these agile maneuvers ...
Phys.org / Queen bees survive winter flooding by breathing underwater
Hibernation is a risky endeavor for many animals, as they can be taken away by the elements or predators. For several months of the year, queen bumblebees enter a dormant state underground called diapause. While this keeps ...
Phys.org / Not one ring but many: Antioxidant enzyme family can assemble in far more diverse ways than previously thought
Peroxiredoxins are among the most abundant enzymes involved in managing oxidative stress. They control the levels of peroxides such as hydrogen peroxide, relay redox signals, and help protect other proteins during stress. ...
Medical Xpress / How the brain filters out 'expected' sounds: Orbitofrontal cortex study offers new insight
Humans and other animals gradually learn what sounds or other sensory cues in their surroundings are meaningful or potentially threatening. Via a process known as habituation, they gradually learn to ignore non-threatening ...
