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 / 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 ...
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 / Improved embryo freezing technique could preserve endangered species
The current practice of freezing embryos—used to assist reproduction in humans or animals or to conserve endangered species—routinely causes ice to form within the cells, ripping through cell membranes, changing the way proteins ...
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, ...
Phys.org / A new approach to urban planning with less car traffic and lower carbon emissions
Urban planning needs to tackle greenhouse gas emissions—and an important way to achieve this is by reducing the number and length of car commutes. This can be achieved primarily by ensuring that homes are located close to ...
Phys.org / Plants exhibit remarkable tolerance to protein translation errors
The precise synthesis of proteins is considered essential for cellular function. Now, a team led by LMU biologists Dr. Benjamin Brandt and Professor Hans-Henning Kunz has demonstrated for the first time that plants can cope ...
Phys.org / A rare blue micromoon rises this weekend
Get set for a rare blue micromoon this weekend—a blue moon that's also the most distant and smallest-looking full moon of the year.
Phys.org / Sensitivity of Antarctic ice to climate change sharply increased after ice age shift, study shows
A new study published in the journal Nature Geoscience by researchers at the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea shows that the Antarctic ice sheet became more sensitive to climate ...
Phys.org / Electromagnetic noise can send migrating bats off course, with effects lasting hours
New research has unearthed new insights into the disruptive and detrimental effects that human-produced electromagnetic noise can have on the ability of bats to migrate effectively. The study, published in the journal Science, ...
