Random by design: Flickering genes may spend energy to achieve precision
Random by design: Flickering genes may spend energy to achieve precision
Inside the cell nucleus, genes must be turned on and off with precision to regulate biological processes. The first models of gene regulation were developed in the 1960s, yet modern science continues to uncover new layers of control. A new study involving researchers from the Ins
Big bees have the most to lose as global CO₂ levels rise: New research
Big bees have the most to lose as global CO₂ levels rise: New research
Pollinators—including bees, flies, wasps, moths, butterflies and some nectar-loving birds—are a cornerstone of our natural environment. By helping plants reproduce, they keep our ecosystems healthy and ensure we can grow vital food crops.
Atoms tell different stories when light hits a molecule in trillionths of a second
Atoms tell different stories when light hits a molecule in trillionths of a second
Researchers have captured how a molecule redistributes energy after absorbing light, differentiating the roles of individual atoms in the process. They used X-ray flashes from the European XFEL to show that different atoms in the same molecule can reveal different aspects of the
Zirconium tweak unlocks stronger cast aluminum alloy with ductility boost
Zirconium tweak unlocks stronger cast aluminum alloy with ductility boost
Researchers at the Department of Materials Engineering (MatE), Indian Institute of Science (IISc), and collaborators have developed a new lightweight cast aluminum alloy that is both exceptionally strong and remarkably ductile, overcoming one of the biggest challenges in the stru
Shrimp feeding behavior observed under simulated microgravity
Shrimp feeding behavior observed under simulated microgravity
The Space Aquaculture Project at Okayama University of Science is an ambitious research initiative aimed at cultivating fish and crustaceans on the moon and Mars, which are expected to serve as food production bases for future space exploration. The project ultimately seeks to im

The family tree of viruses just grew, and it paves the way for a new approach to agricultu
Researchers have discovered that a group of viruses known to infect an agriculturally important plant pathogen has remained genetically stable for an astonishing four decades. The discovery of a disease-fighting virus that doesn't mutate at a rapid rate points the way toward new

Despite the growth of some AI schools like Alpha, research doesn't show that AI tutors are
Over the past decade, the AI-focused, for-profit Alpha School has grown from one campus in Austin, Texas, to more than 15 schools across the country, including in major cities like New York and San Francisco.
New 3D thermal cloak hides objects from heat in any direction
New 3D thermal cloak hides objects from heat in any direction
Researchers have designed and built the first 3D device that can make objects invisible to heat, an advance that could transform how we protect sensitive electronics, manage heat in microchips and shield equipment from thermal detection.
New imaging method reveals how electric fields reshape ferroelectric materials
New imaging method reveals how electric fields reshape ferroelectric materials
New research is shedding light on longstanding debates over the behavior of ferroelectric materials when those materials are exposed to electric fields. The findings stem from the use of a novel technique that allows researchers to observe the real-time behavior of domain walls i
Scientists and citizens are more persuasive than government and industry in mobilizing act
Scientists and citizens are more persuasive than government and industry in mobilizing act
In environmental, health and technology crises, Americans are more persuaded to take action by scientists and public consensus than by leaders in government and industry, according to a study in the Proceedings of the National Academy of Sciences by researchers at Boston College

Where mainshocks strike may explain earthquake size patterns better than timing, data sugg
Japan is well known for its large earthquakes, but not all regions show the same patterns of earthquake activity. One way to understand which places tend to experience large or small earthquakes is the b-value, a key statistical measure long used by researchers to understand seis
Floating-electron catalyst withstands week in air while making ammonia under milder condit
Floating-electron catalyst withstands week in air while making ammonia under milder condit
A surface electrene, BaSiN2:O, developed by researchers at Science Tokyo enables efficient ammonia synthesis under mild conditions while overcoming the long-standing air instability of electrene materials. Synthesized by doping barium silicon nitride with oxygen, the material for
