Malnutrition is a leading cause of death in children under age 5, and nearly 150 million children globally under this age have stunted growth from lack of nutrition. Although an inadequate diet is a major contributor, researchers at Washington University School of Medicine in St. Louis found over a decade ago that dysfunctional communities of gut microbes play an important role in triggering malnutrition. Now, in work done in collaboration with the Salk Institute and UC San Diego, WashU Medicine researchers have discovered that toddlers in Malawi — among the places hardest hit by malnutrition — who had a fluctuating gut microbiome ...

LA JOLLA (September 9, 2025)—Malnutrition is responsible for more than half of all deaths in children under the age of five worldwide. Those who survive can still experience lifelong consequences like cognitive and developmental delays, impaired academic performance, economic instability, and negative maternal health outcomes. This enormous public health issue demands solutions. The latest studies point to gut microbiome—the diverse bacteria, viruses, and other microbes living in our intestines—as a great place to start. Salk Institute researchers ...

A NIMS research team has developed a magnetic tunnel junction (MTJ) featuring a tunnel barrier made of a high-entropy oxide composed of multiple metallic elements. This MTJ simultaneously demonstrated stronger perpendicular magnetization, a higher tunnel magnetoresistance (TMR) ratio (i.e., the relative change in electrical resistance when the magnetization directions of the two ferromagnetic layers switch between parallel and antiparallel alignments) and lower electrical resistance. These properties may contribute to the development of smaller, higher-capacity and higher-performance hard disk drives (HDDs) and magnetoresistive random ...

Ultra-processed foods (UPFs) are industrially altered products – like soda, snacks and processed meats – packed with additives and stripped of nutrients. Hundreds of new ingredients, previously unknown to the human body, now make up nearly 60% of the average adult’s diet and almost 70% of children’s diets in the United States. These products reduce nutritional value, extend shelf life, and tend to increase how much people consume. In the U.S., UPFs account for about 60% of daily calorie ...

In 2012 Max Bazerman, along with four coauthors, published an influential paper showing that “signing first”—that is, promising to tell the truth before filling out a form—produced greater honesty than signing afterward. In 2021, academic sleuths revealed that two of the experiments in the paper were fraudulent, triggering what would become one of the most significant academic frauds of the twenty-first century. In Inside an Academic Scandal, Bazerman tells the sobering story of how fraud in a published paper about inducing honesty upended countless academic careers, wreaked havoc in organizations ...

Phase change emulsions (NPCEs) have significant potential for energy storage and temperature regulation due to their high energy density and efficient heat transfer. However, in most conventional NPCEs, performance under low-temperature and shear conditions is often compromised, leading to droplet coalescence and instability. A team of scientists has developed a high-energy ultrasonic regeneration strategy that enables real-time restoration of NPCE performance without interrupting the operation cycle. Their work was published in the journal Industrial Chemistry & Materials on July 28. “We aim to develop a robust emulsion system that can withstand ...

Barrels filled with industrial waste that were dumped in the sea near Los Angeles more than 50 years ago are creating new microbial ecosystems adapted to highly alkaline conditions. It has been estimated that hundreds of thousands of barrels of waste were dumped off the coast of California in the mid 20th century. Previous investigations suggested that the barrels once contained dichlorodiphenyltrichloroethane (DDT)—an insecticide known for its broad toxicity that was banned for agricultural use in 1972. ...

A living ink containing bacteria attracts coral larvae and could help rebuild reefs. Corals are struggling with water pollution, as well as warming and acidification caused by climate change. One way to support coral reef persistence is to encourage coral recruitment onto the reef. Coral larvae are free-swimming animals that eventually settle onto a surface and transform into a polyp with a hard, durable body. Certain bacteria secrete chemical cues that stimulate settlement and metamorphosis. Settled polyps may then reproduce asexually, expanding the size of the reef. Daniel Wangpraseurt and colleagues created a living material that encourages coral larvae to attach ...

An AI-powered satellite counting effort conducted over two years concludes that less than 600,000 wildebeest migrate across the Serengeti-Mara ecosystem each year—half of previous estimates from manned aircraft surveys. Lions, hyenas, crocodiles, and tourism professionals all rely on the annual migration of wildebeest (Connochaetes taurinus) which transit through Kenya and Tanzania as the herds follow the seasonal growth of grass. Prior estimates of the migratory wildebeest population that make the trek each year were reached by extrapolating counts from aerial photos in the south of the ecosystem. Isla Duporge and colleagues ...

Neurological diseases affect millions worldwide, and the need for long-term patient-friendly treatments has never been greater. While needle-based injections are the standard for most therapies, regular drug injections can often be painful and inconvenient. Microneedles—which are tiny, micron-sized needle systems— have emerged as a promising alternative to conventional needles and offer a pain free way to deliver medicines. However, most existing microneedles are rigid and can cause discomfort during prolonged use and therefore limits their adoption in long-term use. To overcome this, researchers from South Korea have designed a new microneedles system inspired by the ...

The Earth’s tropical regions drive some of the most powerful weather and climate variability globally. Among these, the Madden–Julian Oscillation (MJO) is a dominant intraseasonal climate signal, characterized by large clusters of clouds and rainfall that slowly move eastward across the warm tropical oceans. In doing so, the MJO shapes rainfall patterns, influences tropical cyclones, modulates monsoons, and even impacts weather far beyond the tropics. Understanding the factors that govern its ...
