Phys.org / Revamping ultracold liquid helium microscopy to produce high-resolution images of proteins
A team of researchers at the Medical Research Council Laboratory of Molecular Biology, in the U.K., has re-examined an old liquid-helium-cooled electron microscope, discovered the reason for the lack of improvement in the ...
Phys.org / Fishing bans can help kelp forests withstand marine heat waves
Marine heat waves that seemed extreme just a decade ago will become commonplace by the end of this century in waters favored by giant kelp, researchers have found.
Phys.org / Oil cleanup agents do not impede natural biodegradation, research reveals
Using spill-treating agents to clean up oil spills does not significantly hinder naturally occurring oil biodegradation, according to a new study. The research, published in Applied and Environmental Microbiology, provides ...
Phys.org / Colloidal crystal model reveals new factors in controlling polymorph formation
Polymorphs are not mythical, chimeric beasts—they are substances with identical chemical compositions but differing crystal structures that also exhibit different physical and chemical properties. What this means for practical ...
Phys.org / High-tech sticker can identify real human emotions
Saying one thing while feeling another is part of being human, but bottling up emotions can have serious psychological consequences, such as anxiety or panic attacks. To help health care providers tell the difference, a team ...
Phys.org / Mathematical model modulates the anomalous Hall angle in a magnetic topological semimetal
When an electric current passes through some materials, it generates a voltage perpendicular to the direction in which the current is flowing and of an applied magnetic field. This physical phenomenon, known as the anomalous ...
Phys.org / Astronomers determine the fate of a compact dwarf galaxy
By analyzing the available observational data, astronomers from the Tribhuvan University in Nepal and elsewhere have investigated the properties of a compact dwarf galaxy designated SDSS J134313.15+364457.5 (or J1343+3644 ...
Phys.org / Scientists finally confirm vitamin B1 hypothesis from 1958
Chemists have confirmed a 67-year-old theory about vitamin B1 by stabilizing a reactive molecule in water—a feat long thought impossible. The discovery not only solves a biochemical mystery, but also opens the door to greener, ...
Phys.org / Early medieval European collapse: How imbalanced social-ecological acceleration led to a tipping point
Understanding the acceleration of human impacts on the environment is key to addressing the complex planetary and social challenges of the Anthropocene. But even as the inter-relatedness of environmental, political, and social ...
Phys.org / Astronomers uncover missing merger companion and dark matter bridge in the Perseus cluster
An international team of astronomers has solved one of the longstanding cosmic mysteries by uncovering direct evidence of a massive, long-lost object that collided with the Perseus cluster. Using high-resolution data from ...
Phys.org / It's a quantum zoo out there, and scientists just found a dozen new 'species'
There are a seemingly endless number of quantum states that describe quantum matter and the strange phenomena that emerge when large numbers of electrons interact. For decades, many of these states have been theoretical: ...
Phys.org / How safe is the air to breathe? 50 million people in the US don't know
In 2024, more than 50 million people in the United States lived in counties with no air-quality monitoring, according to a new study from researchers in the Penn State College of Health and Human Development.
