DALLAS – April 22, 2020 – A new protocol using highly sensitive blood tests to determine whether someone is having a heart attack can reduce wait times and overcrowding in emergency departments, according to a new study from UT Southwestern Medical Center.
The findings, published online today in JAMA Open, are particularly meaningful during the current coronavirus pandemic when many people with chest pain may be fearful of going to the hospital.
FLAGSTAFF, Ariz. - Have you ever wondered what kind of rocks make up those bright and dark splotches on the moon? Well, the USGS has just released a new authoritative map to help explain the 4.5-billion-year-old history of our nearest neighbor in space.
For the first time, the entire lunar surface has been completely mapped and uniformly classified by scientists from the USGS, in collaboration with NASA and the Lunar Planetary Institute.
A new way to deliver therapeutic proteins inside the body uses an acoustically sensitive carrier to encapsulate the proteins and ultrasound to image and guide the package to the exact location required, according to Penn State researchers. Ultrasound then breaks the capsule, allowing the protein to enter the cell.
Using just electrostatic charge, common microparticles can spontaneously organize themselves into highly ordered crystalline materials--the equivalent of table salt or opals, according to a new study led by New York University chemists and published in Nature.
"Our research shines new light on self-assembly processes that could be used to manufacture new functional materials," said Stefano Sacanna, associate professor of chemistry at NYU and the study's senior author.
MIAMI--Excessive and sustained rainfall triggered the 2018 eruption of Kīlauea volcano in Hawaii, according to researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science. The researchers suggest that local rainfall patterns may contribute significantly to the timing and frequency of the eruption at Kīlauea and perhaps at other volcanoes.
Electron spin--a fundamentally quantum property--is central to spintronics, a technology that revolutionized data storage,[1] and that could play a major role in creating new computer processors. In order to generate and detect spin currents, spintronics traditionally uses ferromagnetic materials whose magnetization switching consume high amounts of energy.
PROVIDENCE, R.I. [Brown University] -- Researchers have discovered a promising new strategy for combating malaria, a mosquito-borne parasite that claims nearly a half-million lives each year.
CINCINNATI – Although advances in genetics and genomics reveal numerous disease-associated gene mutations, physicians and researchers still wrestle with the tricky challenge of linking those mutations to actual disease-causing processes.
Add this to the growing use of single-cell biology, which detects gene and/or protein expression in each cell at a given moment, and the task becomes even more daunting.
Using induced pluripotent stem cells produced from the skin of a patient with a rare, genetic form of insulin-dependent diabetes called Wolfram syndrome, researchers transformed the human stem cells into insulin-producing cells and used the gene-editing tool CRISPR-Cas9 to correct a genetic defect that had caused the syndrome. They then implanted the cells into lab mice and cured the unrelenting diabetes in those mice.
An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some researchers theorize it happened around four billion years ago, while others think it was closer to one billion.
