NewsResearchers discover highly potent compound that blocks Ebola virus entry
A research team has discovered a highly potent small molecule that blocks Ebola virus entry by stabilizing the virus’s entry protein and provides strong protection when given orally in a preclinical model. It is more than 100 times more potent than previously reported Ebola entry inhibitors.

NewsNew research offers avenue to explore relationship between Alzheimer’s and HIV
Researchers have created an animal model that helps resolve questions about the relationship between HIV and Alzheimer’s disease (AD). The virus that drives the root cause of AD initiates a complex chain that, with other disease partners, drives nerve cell injury and cognitive impairments for AD pathology.

NewsProbiotic use surges - but microbiome-supportive food consumption stagnates
New research finds that probiotic supplement use has surged in the United States, while the consumption of microbiome-supportive foods has remained virtually unchanged. According to a study published in Clinical Gastroenterology and Hepatology, the consumption of probiotic supplements increased 287% among adults from 2009-2023 and 786% among ...

NewsToxic tail: Biologists find a hidden weak spot in how bacteria build the tails they use to move
New research has uncovered a previously unknown vulnerability in how bacteria build the whip-like tails they use to move. Building these tails can put stress on the protective wall surrounding a bacterial cell, and uncovered systems bacteria use to keep that stress from becoming destructive.

NewsHelicobacter pylori exposure may be linked to more than 1 in 5 bowel cancer cases worldwide
Exposure to the stomach microbe Helicobacter pylori may be associated with more than 1 in 5 cases of bowel cancer worldwide, suggests an exploratory risk attribution study - and those born in more recent decades may be more at risk of the disease after exposure.

NewsBacterial trial fails to demonstrate early asthma prevention - prompting rethink of 'hygiene hypothesis'
A national clinical trial has found that treating young children with an oral bacterial extract did not reduce the risk of severe wheezing and respiratory illnesses that can precede asthma, potentially prompting researchers to rethink aspects of the hygiene hypothesis.

NewsBlueberry’s waxy shield reveals clues to gray mold resistance
Botrytis cinerea is a broad-host-range necrotrophic fungus that causes gray mold in more than 1,000 plant species. In blueberry, it can damage flowers in the field and later emerge as fruit rot after harvest, reducing shelf life, shipment quality and market value. The disease is especially challenging because latent infections ...

NewsBacteria can make testosterone. What could that mean for prostate cancer?
Scientists have identified an unexpected participant in androgen chemistry: a bacterium from the human urinary tract that can convert the steroid precursor DHEA into testosterone under laboratory conditions. It reveals a previously unknown microbial route to a hormone that is central to prostate biology.
