Shigella bacteria can infect humans but not mice. In the March 29 issue of Nature, a team from UConn Health explains why. Their findings may explain the multifariousness of a key weapon of our immune system. Shigella infections cause fever, stomach pain, and prolonged, sometimes bloody diarrhea for as long as a week. The bacteria sicken 450,000 people each year in the US alone. Although most people recover on their own, children and those with weakened immune systems are at risk of Shigella ...

An international team of researchers, led by Drexel University, has found that a thin coating of MXene — a type of two-dimensional nanomaterial discovered and studied at Drexel for more than a decade — could enhance a material’s ability to trap or shed heat. The discovery, which is tied to MXene’s ability to regulate the passage of ambient infrared radiation, could lead to advances in thermal clothing, heating elements and new materials for radiative heating and cooling. The group, including materials science ...

Photocatalysis is the use of light to accelerate the rate of a reaction in the presence of a photocatalyst. The catalyst plays a crucial role in this process—it absorbs the light being shined onto it and makes it available in way that can help accelerate the chemical reaction and also enhance it. These catalysts are used for a variety of light-dependent reactions ranging from the production of paper to the conversion of carbon dioxide to fuel. Given these applications, the development of ideal photocatalysts is important. An ideal ...

UPTON, NY—Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have produced the first atomic-level structure of an enzyme that selectively cuts carbon-hydrogen bonds—the first and most challenging step in turning simple hydrocarbons into more useful chemicals. As described in a paper just published in Nature Structural & Molecular Biology, the detailed atomic level “blueprint” suggests ways to engineer the enzyme to produce desired products. “We want to create a ...

Why do cancer immunotherapies work so extraordinarily well in a minority of patients, but fail in so many others? By analysing the role of neutrophils, immune cells whose presence usually signals treatment failure, scientists from the University of Geneva (UNIGE), from Harvard Medical School, and from Ludwig Cancer Center have discovered that there is not just one type of neutrophils, but several. Depending on certain markers on their surface, these cells can either promote the growth of tumours, or fight them and ensure the success of a treatment. By boosting the appropriate factors, neutrophils could become great agents of anti-tumour ...

Summary Scientists have come up with a new method to study the mechanical properties of developing embryos with unprecedented speed The new method – line-scanning Brillouin microscopy (LSBM) – relies on a microscopy technique based on Brillouin scattering – a phenomenon where light interacts with naturally occurring thermal vibrations within materials. The method, which can be used to non-invasively study developing embryos in three dimensions and across time, was selected as one of The Guardian's ...

A new UC San Francisco-led study brings scientists closer to understanding the causes of a mysterious rash of cases of acute severe hepatitis that began appearing in otherwise healthy children after COVID-19 lockdowns eased in the United States and 34 other countries in the spring of 2022. Pediatric hepatitis is rare, and doctors were alarmed when they started seeing outbreaks of severe unexplained hepatitis. There have been about 1,000 cases to date; 50 of these children needed liver transplants and at least 22 have died. In the study, publishing on March 30 in Nature, researchers linked the disease to co-infections from multiple common viruses, in particular a strain of ...

CAMBRIDGE, MA -- Engineers at MIT and the University of Massachusetts Medical School have designed a new type of nanoparticle that can be administered to the lungs, where it can deliver messenger RNA encoding useful proteins. With further development, these particles could offer an inhalable treatment for cystic fibrosis and other diseases of the lung, the researchers say. “This is the first demonstration of highly efficient delivery of RNA to the lungs in mice. We are hopeful that it can be used to treat or repair ...

HOUSTON ― A novel approach to administer intrathecal (IT) immunotherapy (directly into the spinal fluid) and intravenous (IV) immunotherapy was safe and improved survival in a subset of patients with leptomeningeal disease (LMD) from metastatic melanoma, according to interim analyses of a Phase I/Ib trial led by researchers at The University of Texas MD Anderson Cancer Center. The study, published today in Nature Medicine, represents the first-in-human trial of concurrent IT and IV nivolumab (anti-PD-1) in melanoma patients ...

White blood cells called neutrophils have an unappreciated role in eradicating solid tumors, according to a surprise discovery from a team led by Weill Cornell Medicine scientists. In the study, published March 30 in Cell, the researchers investigated how a T cell-based immunotherapy was able to destroy melanoma tumors even though many of the tumor cells lacked the markers or “antigens” targeted by the T cells. They found that the T cells, in attacking the tumors, activated a swarm of neutrophils—which in turn killed the tumor cells that the T cells couldn’t ...

Hydrogen production powered by wind and solar energy is still too expensive if it is to play a role in the clean transition via energy storage and to help decarbonize hard-to-electrify sectors. Much effort in reducing its cost focuses on enhancing production efficiency by improving the performance of iridium-based catalysts that can speed up the oxygen-related part of the electrochemical reaction involved in splitting water into its component parts, hydrogen and oxygen. A new review of the state of the field discusses its recent progress and challenges and identifies research gaps that need to be filled before such ...

(WASHINGTON, March 30, 2023) – Chimeric antigen receptor T-cell (CAR-T) therapy has transformed cancer treatment, yet relatively few studies have investigated the impact of the therapy on longitudinal patient quality of life – an aspect of care that often suffers from receiving traditional intensive cancer medications, such as chemotherapy. A new study published in Blood Advances demonstrates that some effective cancer treatments do improve quality of life, revealing that patients with blood cancers experienced ...

LOS ANGELES — A newly published study paves the way for some patients with testicular cancer to avoid chemotherapy and radiation. Seminoma is a slow-growing form of testicular cancer that if untreated, typically metastasizes (spreads) to lymph nodes in an area behind the abdomen lining called the retroperitoneum. The standard treatment for patients at this stage is chemotherapy and radiation to shrink and kill the cancerous lymph nodes.   While effective, chemotherapy and radiation are associated with long-term side effects, such as cardiovascular disease and secondary cancers, that adversely affect a patient’s quality of life. Now, however, the results of a multi-institutional ...
