Study published in Nature Medicine confirms that Butantan-DV protects against hospitalizations.

Researchers at the University of Gothenburg, Sweden, have identified a protein linked to an increased risk of metastasis and recurrence in lung cancer. The findings are presented in a study in Nature that paves the way for new precision medicine approaches, particularly for older patients.

Pyrogenic carbon, a carbon rich material produced when biomass burns or is converted into biochar, is widely found in soils, sediments, and aquatic environments around the world. Scientists have long known that this material can influence environmental chemical reactions by transferring electrons, but how its properties change as it ages in nature has remained unclear.

In the summer of 2023, a large outbreak occurred at several Calgary daycare centres resulting in hundreds of children becoming sick from exposure to a severe strain of E. coli. Shiga toxin-producing Escherichia coli (STEC) is a bacterium that can cause bloody diarrhea. One in five infected children experience life-threatening complications. Research conducted by University of Calgary scientists informed collaborative, evidence-based care during the outbreak. The coordinated efforts resulted in fewer kids getting serious complications.

Thirteen million years ago, a medium-sized monkey known for guarding its territory among the treetops with a fearsome “howl” started doing something new. This monkey, one of the oldest known ancestors of the modern howler monkey, started eating leaves, causing them to evolve a larger body size and differentiate themselves from other primates, says a team of researchers led by a scientist at Johns Hopkins Medicine.

Tick-borne diseases are on the rise in the northeastern US, with many ticks carrying more than one pathogen. So reports a recent analysis published in Ecosphere by researchers at Cary Institute of Ecosystem Studies and the SUNY Center for Vector-Borne Diseases at Upstate Medical University.

Despite widespread exposure, only some newborns become severely ill from E.coli infections. That's because mothers pass along protective antibodies to their babies in most cases, a new study in Nature reports. In mice, tests show that a probiotic can help when offspring lack those protective antibodies.

Prior exposure to one strain of influenza virus may weaken children’s ability to mount an effective antibody response against their subsequent exposure to a different flu strain, according to a study led by Weill Cornell Medicine investigators. The analysis of the pediatric response to H3N2 and H1N1 influenza A viruses, two of the most common causes of flu, provides insight into the concept of “immune imprinting,” and supports the idea that childhood vaccination, if properly designed, may be able to mitigate its adverse effects.
