Phys.org / How bacteria survive with almost no oxygen— and why blocking one enzyme could aid new antibiotics
Researchers in Leiden have, for the first time, observed how a specialized enzyme helps bacteria stay alive when oxygen levels are low, and how that process can be blocked. The study, published in Science Advances, opens ...
Phys.org / Ultrafast holographic imaging reveals electron and magnetic dynamics inside next-generation materials
An extremely fast microscopy method to research the interaction of light and matter makes it possible to study optical processes on very short timescales. To this end, a German–Italian research team is combining holographic ...
Phys.org / Shock waves show how baby stars' cradles get their radial shape in 3D simulations
The universe is full of fascinating structures, and some of the most striking take shape inside the giant clouds where stars are born. There, streams of gas appear to converge from all directions toward a dense central hub, ...
Phys.org / Why the most massive galaxies in the early universe stopped forming stars prematurely
Astronomical observations show that the most massive galaxies in the early universe formed approximately three to four billion years after the Big Bang and stopped producing stars very early in cosmic history, around one ...
Phys.org / Silver nanoparticles enable assembly of a theorized, previously unobserved crystal metallic structure
Using finely tuned nanoscale building blocks, researchers from Brown University and the University of Michigan College of Engineering have stabilized a fleeting structural phase of matter that had been predicted theoretically ...
Phys.org / How do you know a bowhead whale is feeding? It's all in the way it moves, shows study
For years, scientists studying bowhead whales have relied on a simple idea: if a whale makes a long, square or U-shaped dive, it's feeding time. A new study demonstrates that assumption may not hold water.
Phys.org / Human-linked foraging reshapes dolphin social networks in Florida over decades
Wild dolphins are known for their complex social lives, but new research shows those social networks can be influenced by human activity.
Phys.org / A 'Balrog' in the tunnels: Scientists discover a new cave cricket species on the tiny island of Kastellorizo, Greece
Despite the intensity of modern exploration, the eastern Mediterranean continues to yield unexpected discoveries. On the small Greek island of Kastellorizo, researchers have documented a previously unknown cave cricket thriving ...
Phys.org / Spin wave signals used in computing boosted more than 5,000 times in Z-shaped path approach
A research team from Tohoku University, Shin-Etsu Chemical Co., Ltd., and École Polytechnique Fédérale de Lausanne (EPFL) has invented a new way to efficiently guide spin waves around sharp corners with minimal loss—representing ...
Phys.org / MIZ-ing in action: How much of Antarctic sea ice is affected by waves?
Using old satellite radar techniques, scientists have developed a new way of measuring the true extent of an understudied and crucial region of the Antarctic sea-ice system for the first time. The Marginal Ice Zone (MIZ) ...
Phys.org / 'Diversifying' social feeds can cut exposure to toxic content and preserve enjoyment
A new study from Northwestern University and the University of Chicago offers underlying evidence that the engagement-based algorithms used by major social media platforms amplify intergroup, moralized, emotional (IME) and ...
Phys.org / Italians and Dutch share the same gestural instinct for teaching, research reveals
Italians are famous for speaking with their hands. But a new international study suggests that when it comes to teaching children, adults everywhere instinctively become more expressive with their gestures—even in cultures ...
