The visit home brings a special chance for the spacecraft to collaborate with NASA missions near Earth and reveal new insights into our closest star. The…
Text-to-image (T2I) generative artificial intelligence tools are increasingly powerful and widespread tools that can create nearly any image based on just a few inputted words. T2I generative AI can create convincingly realistic photos and videos which are being used more and more for a multitude of purposes, from art to…
Microscopic plastic particles have been found in the fats and lungs of two-thirds of the marine mammals in a graduate student’s study of ocean microplastics. The presence of polymer particles and fibers in these animals suggests that microplastics can travel out of the digestive tract and lodge in the tissues.…
Sodium, Potassium and zinc have all been promising contenders for lithium’s place in rechargeable batteries of the future, but researchers at Worcester Polytechnic Institute (WPI) have added an unusual and more abundant competitor to the mix: chloride, the richest negatively charged ions in seawater. Xiaowei Teng, the James H. Manning…
The best heart rate for burning fat differs for each individual and often does not align with the “fat burning zone” on commercial exercise machines, Icahn School of Medicine at Mount Sinai researchers report. Instead, the researchers said, clinical exercise testing — a diagnostic procedure to measure a person’s physiological…
A new analysis shows that infectious bacteria exposed to the antibiotic albicidin rapidly develop up to a 1,000-fold increase in resistance via a gene amplification mechanism. Mareike Saathoff of Freie Universität Berlin, Germany, and colleagues present these findings August 10 in the open access journal PLOS Biology. Bacterial resistance to…
Cancer cells can evade the body’s immune defenses by exploiting a normally helpful and ubiquitous group of molecules known as mucins. Now, Stanford researchers have engineered a biomolecule that removes mucins specifically from cancer cells — a discovery that could play a significant role in future therapies for cancer. Mucins…
A new study published in the journal Science by an international team finds that past changes in atmospheric CO2 and corresponding shifts in climate and vegetation played a key role in determining when and where early human species interbred. Modern-day people carry in their cells a small quantity of DNA…
A new study published in the journal Science finds that around 1.12 million years ago a massive cooling event in the North Atlantic and corresponding shifts in climate, vegetation and food resources disrupted early human occupation of Europe. The study published by an international group of scientists from the UK,…
Scientists at UCLA David Geffen School of Medicine and UCLA Health led an international research team that published two articles detailing changes in DNA — changes that researchers found are shared by humans and other mammals throughout history and are associated with life span and numerous other traits. “We’ve discovered…
Plants orient their organs in response to the gravity vector, with roots growing towards gravity and shoots growing in the opposite direction. The movement of statoliths responding to the inclination relative to the gravity vector is employed for gravity sensing in both plants and animals. However, in plants, the statolith…
Physicists now have a brand-new measurement of a property of the muon called the anomalous magnetic moment that improves the precision of their previous result by a factor of 2. An international collaboration of scientists working on the Muon g-2 experiment at the U.S. Department of Energy’s Fermi National Accelerator…
For now, cyborgs exist only in fiction, but the concept is becoming more plausible as science progresses. And now, researchers are reporting in ACS’ Nano Letters that they have developed a proof-of-concept technique to “tattoo” living cells and tissues with flexible arrays of gold nanodots and nanowires. With further refinement,…
Scientists can finally hunt down a harmful kind of human T cell, thanks to new research led by scientists at La Jolla Institute for Immunology (LJI) and the Medical College of Georgia (MCG) at Augusta University. Immune cells called ex-T regulatory cells (exTregs) tend to be rare in the body…
Long COVID can persist for at least a year after the acute illness has passed, or appear months later, according to the most comprehensive look yet at how symptoms play out over a year. The multicenter study, a collaboration between UC San Francisco, the Centers for Disease Control and Prevention…
A change in just one letter in the code that makes up a cancer-causing gene can significantly affect how aggressive a tumor is or how well a patient with cancer responds to a particular therapy. A new, very precise gene-editing tool created by Weill Cornell Medicine investigators will enable scientists…
As butterflies flit among flowers, they don’t all view blossoms the same way. In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. University of California, Irvine biologists have discovered that in at least one species, the variation…
A vacuum chamber is never perfectly empty. A small number of atoms or molecules always remain, and measuring the tiny pressures they exert is critical. For instance, semiconductor manufacturers create microchips in vacuum chambers that must be almost entirely devoid of atomic and molecular contaminants, and so they need to…
Pushing into a new chapter of technologically advanced biological sensors, scientists from the University of California San Diego and their colleagues in Australia have engineered bacteria that can detect the presence of tumor DNA in a live organism. Their innovation, which detected cancer in the colons of mice, could pave…
CNN — A mandatory evacuation has been ordered for the Ukrainian city of Kupyansk and its surrounding areas, as Russia intensified shelling of Ukraine’s northeastern Kharkiv region and claimed to have captured Ukrainian positions near the city on Thursday. Kupyansk, which lies close to the Russian border, fell to Moscow’s…
Concealed guns significantly impact homicide rates and public safety, according to a Rutgers study that found an increase in homicides based on the number of concealed carry weapons licenses issued.
