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 / 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 / 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 / Deep beneath Utah, rare mantle earthquakes reshape seismic hazard questions
Nearly 50 years ago, a puzzling earthquake beneath northern Utah jolted scientists' understanding of how Earth works. Now, research from the University of Utah confirms that the mysterious event was real, and part of a rare ...
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 / 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 / Cells trap heat in ways standard fluid physics cannot explain, study finds
Living cells cool much slower than our current understanding of heat conduction can explain, according to new research from the University of Tokyo. Researchers have used two techniques—high-speed temperature mapping and ...
Phys.org / Global food shock model reveals self-sufficiency alone may not prevent crises
Global food systems are fragile. Recent shocks such as the closure of the Strait of Hormuz and the Russian invasion of Ukraine have raised prices and exacerbated food insecurity. Governments are increasingly trying to shield ...
Phys.org / Electrical 'knob' can switch light on, off and tune intensity at the nanoscale
Physicists from Emory University have led work to develop a microscopic, nonlinear light source that can be switched on, off or tuned to a particular intensity by an electrical "knob." The paper is published in the journal ...
Phys.org / Astronomers discover how to estimate masses of newborn planets using dust rings
A team of astronomers, led by University of Warwick in collaboration with researchers at MIT and McMaster, have developed a novel method to use the properties of dust rings around stars to estimate the masses of newborn planets. ...
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 / Biologists improve biomass mapping tools to better track carbon storage
In the far north regions of Earth, where forests stretch across Alaska and Canada, climate change is unfolding at an accelerated pace. Arctic and boreal regions are warming two to four times faster than the global average, ...
