Differences in alcohol metabolism play a role in the severity of alcohol hangovers
Hangovers are common among people who drink alcohol. Previous research showing that a hangover’s combination of both mental and physical misery can occur after a single episode of alcohol consumption also revealed that a rapid breakdown of alcohol into acetaldehyde is associated with less severe hangovers. Findings from an investigation of the metabolic influence of oral microbiota on hangover severity will be shared at the 46th annual scientific meeting of the Research Society on Alcohol (RSA) in Bellevue, Washington.

RPI Researchers To Develop New Market for Farm Waste
There are more than 80,000 sheep and lambs living on over 2,000 farms in New York State. Their wool has many uses including clothing, carpets, furniture, bedding, insulators, fertilizers, and more. However, about 10-15% of wool is wasted during the sorting and cleaning processes. Researchers from Rensselaer Polytechnic Institute are aiming to turn that waste into a new profit source for farmers, and produce an eco-conscious, high-performance yarn in the process.

Microbes can create a more peaceful world: Scientists call to action
The paper ‘Weaponising microbes for peace’ by Anand et al, outlines the ways in which microbes and microbial technologies can be used to tackle global and local challenges that could otherwise lead to conflict, but warns that these resources have been severely underexploited to date.
It Isn’t the Picky Eaters that Drive Soil Microbial Metabolism
How do microbes in soil communities interact to release nutrients from material in the soil? Researchers have discovered that microbes able to break down one type of available food, chitin, are critical for the community’s success but do not necessarily grow the fastest. Instead, species with the ability to use a wide range of food sources produced by other members of the community become the most abundant. The researchers also found that individual microbes can change their behavior when grown alone or in the community.
Same same but different
A method for detecting intraspecies genomic diversity of uncultivated bacterial DNA has been developed. This enhanced MAG method’s ability to detect previously overlooked variations focuses on the DNA sequence and structural traits of the genome. The spectrum of microdiversity in environmental bacterial genomes has been found to be broader than expected.

UC San Diego researchers describe how the microbiomes of people and the homes they live in interact and change each other.
Lower Airways Are Distinct in Cystic Fibrosis Even at Younger Ages
In the largest study of its kind, researchers found that the lower airways in children with cystic fibrosis (CF) have a higher burden of infection, more inflammation and lower diversity of microorganisms, compared to children with other illnesses who also have lung issues. They noted a clear divergence in these bacterial communities in toddlers, which is typically before progressive lung disease takes hold in patients with CF. Their findings, published in the journal PLOS ONE, could help providers target specific pathogens earlier, treat them and potentially prevent more severe lung disease.
Inspired by bacteria and sperm, scientists make micro-robot swimmers
Scientists at Cornell University have created cell-size robots that can be powered and steered by ultrasound waves. Despite their tiny size, these micro-robotic swimmers – whose movements were inspired by bacteria and sperm – could one day be a formidable new tool for targeted drug delivery.
