How molecular motor proteins are involved in malaria transmission
Scientists at the University of Nottingham have made a major breakthrough in understanding how malaria parasites divide and transmit the disease, which could be a major step forwards in helping to prevent one of the biggest killer infections in the world. Malaria is still the deadliest parasitic disease worldwide, with approximately 241 million cases and […]
Music-making and the flow of aerosols
The latest research from the labs of Penn scientists Paulo Arratia and Douglas Jerolmack was an answer to “a call for help,” says Arratia. It was 2020, and the Philadelphia Orchestra, like so many cultural institutions, had suspended performances due to the COVID-19 pandemic. Through P.J. Brennan, chief medical officer of the University of Pennsylvania […]
What to Know About the New BA.2.75 Omicron Subvariant
Even as BA.4 and BA.5 continue to climb the charts, crowding out earlier Omicron subvariants, scientists are warning about an even newer strain: BA.2.75. Tom Peacock, PhD, a virologist at Imperial College London, tweeted on June 30, “worth keeping a close eye on BA.2.75 — lots of spike mutations, probable second generation variant, apparent rapid […]
How sound reduces pain in mice: Newly identified brain circuits may point to more effective pain therapies
An international team of scientists has identified the neural mechanisms through which sound blunts pain in mice. The findings, which could inform development of safer methods to treat pain, were published in Science. The study was led by researchers at the National Institute of Dental and Craniofacial Research (NIDCR); the University of Science and Technology […]
‘You are what you eat,’ and now researchers know exactly what you’re eating: Matching blood or stool samples to a reference database of foods reveals how much of our body chemistry is traceable to what we consume
An international team of scientists, led by researchers at University of California San Diego, report a new method called untargeted metabolomics to identify the vast number of molecules derived from food that were previously unidentified, but that appear in our blood and our stool. The method, described in the July 7, 2022 issue of Nature […]
Researchers expand understanding of vortex spread in superfluids
An international team of scientists featuring Florida State University researchers has developed a model that predicts the spread of vortices in so-called superfluids, work that provides new insight into the physics that govern turbulence in quantum fluid systems such as superfluid neutron stars. In a paper published in Physical Review Letters, the researchers created a […]
Bacteria for blastoff: Using microbes to make supercharged new rocket fuel: Scientists have developed a new class of energy-dense biofuels based on one of nature’s most unique molecules
Biofuel scientists used an oddball molecule made by bacteria to develop a new class of sustainable biofuels powerful enough to launch rockets. The candidate molecules have greater projected energy density than any petroleum product, including the leading aviation and rocket fuels, JetA and RP-1. Converting petroleum into fuels involves crude chemistry first invented by humans […]
No more binge eating: Signal pathway in the brain that controls food intake discovered
A group of researchers has developed an entirely novel approach to treating eating disorders. The scientists showed that a group of nerve cells in the hypothalamus (so-called AgRP, agouti-related peptide neurons) control the release of endogenous lysophospholipids, which in turn control the excitability of nerve cells in the cerebral cortex, which stimulates food intake. In […]
Women’s heart attacks are often missed: This gene may help explain why
When diagnostic tests for the heart were first created, scientists at the time did not fully consider that no two bodies are the same, especially between the sexes. According to University of Florida College of Nursing associate professor Jennifer Dungan, many of the current symptom profiles and lab tests for heart disease do not accurately […]
Study identifies unique underlying molecular factors driving melanoma development
A new study reveals important molecular information that could help scientists develop more effective treatment and prevention strategies for a difficult-to-treat form of melanoma skin cancer. In this new report, The Ohio State University Comprehensive Cancer Center — Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC — James) researchers identify and […]
