Phys.org / Hawai'i high school students name image of glittering galaxy pair
Nā ʻUhane Māhoe Huki Pū i ke Ola is the Hawaiian name given to NGC 7253—a pair of spiral galaxies caught in each other's gravity. Captured by the Gemini North telescope on Maunakea in Hawai'i, the image created a spectacular ...
Phys.org / How Mercury formed its graphite crust and core
As the BepiColombo mission prepares to enter the final phase of its journey to Mercury, a series of studies conducted by researchers at the University of Liège and KU Leuven sheds new light on the early stages of the evolution ...
Medical Xpress / Energy-hungry tissues expand cleanup crews to clear worn-out mitochondria
The body's heart muscle (for pumping blood), skeletal muscle (for movement and posture) and brown fat (for heat production) each require a lot of energy and make a lot of waste. That waste needs to be managed.
Phys.org / Sound waves and water droplets transform paper waste into higher-value chemical compound
Researchers at the University of Illinois Urbana-Champaign have developed a fast, simple way to turn lignin, a plentiful plant-based byproduct of the papermaking industry, into potentially more valuable renewable chemicals.
Medical Xpress / CRISPR gene-editing therapy safely and continuously lowers cholesterol and triglycerides, first-in-human trial shows
A Cleveland Clinic first-in-human clinical trial has shown that a one-time infusion of a gene-editing therapy using CRISPR-Cas9 was effective and safe in reducing LDL ("bad") cholesterol and triglycerides in people with medication-resistant ...
Medical Xpress / Diabetes drug metformin could be repurposed to help slow aging mechanisms
Metformin, a widely prescribed, safe and inexpensive drug for type 2 diabetes, is a first-line treatment that lowers blood sugar and improves the body's response to insulin. The drug appears to trick cells into sensing an ...
Medical Xpress / Cancer drug tames atherosclerosis inflammation and plaque in animal models
A new Yale study has identified a promising therapeutic avenue for atherosclerosis, a condition caused by inflammation and plaque buildup in arteries. Martin Schwartz, Ph.D., Robert W. Berliner Professor of Medicine (Cardiology) ...
Phys.org / Virus-like particles enable gene activity tracking over time in the same cells
In recent years, scientists have developed methods to measure a cell's transcriptome, or all the RNA produced by a cell, to study the cell's identity and genetic activity. However, these methods rely on killing the cell to ...
Phys.org / Embedded platinum channels bring nanoscale spin-based thermoelectric conversion to bulk materials
A joint research team from NIMS and the University of Tokyo has developed a new composite in which three-dimensional nano-interfaces are distributed throughout the material by coating the surfaces of magnetic-insulator powders ...
Medical Xpress / Early mitochondrial stress reveals potential mechanism for lasting heart protection
Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do much more—including acting as signaling hubs. Some signals that mitochondria send can reprogram the activity of the entire ...
Phys.org / Salt may have helped turn Earth into a frozen world 700 million years ago
Earth may have been pushed deeper into a global deep freeze by something surprisingly ordinary: salt. Around 700 million years ago, Earth entered periods of extreme glaciation known as Snowball Earth, when ice is thought ...
Phys.org / Archaea as 'flexitarians': Ammonia-oxidizing microbes also feed on amino acids
Symbiotic ammonia-oxidizing archaea in marine sponges are not strict specialists but true "flexitarians." A team led by microbiologists Bettina Glasl and Katharina Kitzinger from the University of Vienna, in collaboration ...
