Cleveland:  Cleveland Clinic researchers have discovered a connection between elevated blood levels of TMAO (trimethylamine N-oxide) — a byproduct of gut bacteria digestion of nutrients found in red meat and other animal products — and a higher risk of abdominal aortic aneurysms.   The findings, published today in JAMA Cardiology, suggest that TMAO may play a role in the development, progression, and severity of this life-threatening condition, including faster rates of aneurysm expansion and greater risk for needing surgery.  “These results suggest targeting TMAO levels may help prevent and treat aneurysmal disease ...

An international team of scientists, led by Northwestern University astrophysicists, has detected a never-before-seen type of exploding star, or supernova, that is rich with silicon, sulfur and argon. When massive stars explode, astrophysicists typically find strong signatures of light elements, such as hydrogen and helium. But the newly discovered supernova, dubbed SN2021yfj, displayed a startling different chemical signature. Astronomers long have theorized that massive stars have a layered structure, similar to an onion. The outermost layers predominantly comprise the lightest elements. As the layers move inward, the elements become heavier and heavier until reaching ...

Blocking brain damage triggered by a glioblastoma, an aggressive brain cancer, may slow the growth of the cancer and allow the brain to keep working better for longer, according to a new study led by UCL (University College London) researchers. The study, published in Nature and funded by the Brain Tumour Charity and Cancer Research UK, looked at glioblastomas in mice. It found that early-stage tumours damaged parts of nerve cells called axons, and that the brain’s natural response to this injury – breaking down and clearing away these damaged axons – accelerated the tumour’s growth. Mice ...

Most metals found in nature are actually in their oxide forms. To extract those metals to use in critical applications — ranging from infrastructure such as bridges and buildings to advanced technologies like airplanes, semiconductors or even quantum materials — those oxides must be reduced with gases. A new study illuminating how different gases can affect oxide reduction, however, has the potential to revamp scientific understandings and current industrial practices.  Hydrogen or carbon monoxide are typically used as reductants, ...

Using a small bench-top reactor, researchers at the University of British Columbia (UBC) have demonstrated that electrochemically loading a solid metal target with deuterium fuel can boost nuclear fusion rates.   Large-scale magnetic confinement fusion—which puts plasmas under extreme temperatures and pressure—is being widely explored as a method for clean energy generation. The experiment published today in Nature takes an entirely different approach—with a more ...

Effectively managing chronic conditions like diabetes and hypertension can greatly improve quality of life, reduce complications and extend longevity for older adults. However, when treatment becomes overly aggressive, it can do more harm than good. Every day, thousands of vulnerable older adults in the United States are harmed by intensive management of these conditions – resulting in dangerously low blood sugar or blood pressure, emergency visits, hospitalizations, disability or even death. These harms are ...

PULLMAN, Wash. — In Guatemalan communities, a recent visit to a health clinic or hospital — not antibiotic use — is the strongest predictor of carrying bacteria resistant to critical antibiotics, according to a new study led by Washington State University. Previous research in Guatemala’s Western Highlands found nearly 46% of residents were colonized in the gastrointestinal tract with bacteria known as extended-spectrum cephalosporin-resistant Enterobacterales (ESCrE). These bacteria, often E. coli, can render the commonly used and important antibiotic ceftriaxone ineffective, complicating care for infections such as pneumonia or ...

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has successfully localized core Radar Stealth technologies through indigenous development, without reliance on foreign technologies. This achievement is a significant milestone, laying the foundation for the establishment of stealth weapon systems in Korea, which have long been difficult to import due to their classification as national strategic military assets.

When SARS-CoV-2, the coronavirus that causes COVID-19, began spreading worldwide in 2020, many research teams immediately set to work developing a vaccine against it. Building on decades of previous work on mRNA technology and on other viral vaccines, including HIV, they achieved their goal within the year. The most widely used mRNA vaccine design contains the genetic instructions for the body to make the spike protein that the virus uses to enter cells. The resulting immune response protects against infection and, more importantly, disease and death. However, ...

A team of scientists from Korea and Japan has discovered a new type of crystal that can "breathe"—releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices. The newly developed material is a special kind of metal oxide made of strontium, iron, and cobalt. What makes it extraordinary is that it can release oxygen when heated in a simple gas environment and then take it back in, all without falling apart. This process can be repeated many times, making it ideal for real-world applications. This ...

Establishing robust isolated spins on solid surfaces is crucial for fabricating quantum bits or qubits, sensors, and single-atom catalysts. An isolated spin is a single spin that is shielded from external interactions. Because isolated spins can maintain their state for long periods, they are ideal for use as qubits, the basic units of quantum computation, and for ultrafast spintronic memory.  Consequently, significant research has been dedicated to identifying materials capable of producing a stable isolated quantum spin. Candidates include single atoms of transition metals such as copper (Cu) in the Cu-phthalocyanine molecule (CuPc), molecular magnets, nitrogen-vacancy ...

Omega fatty acids could protect against Alzheimer’s disease in women, new research has found. Analysis of lipids – fat molecules that perform many essential functions in the body – in the blood found there was a noticeable loss of unsaturated fats, such as those that contain omega fatty acids, in the blood of women with Alzheimer’s disease compared to healthy women. Scientists found no significant difference in the same lipid molecule composition in men with Alzheimer’s disease compared to healthy men, ...

WASHINGTON, Aug. 20, 2025 — How do you identify something no one has a test for? Designer drugs replicate the effects of known, illicit drugs but evade law enforcement. The chemical structure variations that help these compounds avoid detection also make them unpredictable in the body — a quality that poses serious health consequences. Now, a research team has used computer modeling to create a database of predicted chemical structures for improved detection of designer drugs. Jason Liang, a rising senior in the Science, Mathematics and Computer Science Magnet Program at Montgomery Blair High School, will present the team’s ...

UCSF scientists caught cancer cells in the act of breaking into fat cells and releasing their fat. The energy heist seems to be critical for the growth of deadly breast cancer.  When triple-negative breast cancer grows, the fat cells around it seem to shrink.   UCSF researchers have discovered that the cells of these tumors, which are among the deadliest types of breast cancer, build molecular tunnels, called gap junctions, into nearby fat cells. The tumor cells then send instructions that trigger the fat cells to release stores of energy that could feed the cancer.   Blocking the ...
