Air Pollution From Oil and Gas Causes 90,000 Premature US Deaths Each Year, Says New Study

2 months 1 week ago
Air pollution from oil and gas causes more than 90,000 premature deaths and sickens hundreds of thousands of people across the US each year, a new study shows, with disproportionately high impacts on communities of color. From a report: More than 10,000 annual pre-term births are attributable to fine particulate matter from oil and gas, the authors found, also linking 216,000 annual childhood-onset asthma cases to the sector's nitrogen dioxide emissions and 1,610 annual lifetime cancer cases to its hazardous air pollutants. The highest number of impacts are seen in California, Texas, New York, Pennsylvania and New Jersey, while the per-capita incidences are highest in New Jersey, Washington DC, New York, California and Maryland.

Scientists Unlock Secret To Thick, Stable Beer Foams

2 months 1 week ago
Swiss researchers have determined that fermentation degree controls beer foam stability after seven years of study published in Physics of Fluids. Triple-fermented Belgian beers maintained the longest-lasting foam while single-fermented lagers produced the shortest duration. The team tested six commercial beers including Westmalle Tripel, Tripel Karmeliet, and Swiss lagers Feldschlosschen and Chopfab. Surface viscosity dominated foam stability in single-fermented beers. Marangoni stresses from surface tension differences stabilized double- and triple-fermented beer foams. Lipid transfer protein 1 underwent progressive denaturation through successive fermentations. Single fermentation produced small round protein particles. Double fermentation created net-like protein structures. Triple fermentation broke proteins into hydrophobic and hydrophilic fragments that function as surfactants. ETH Zurich's Jan Vermant said breweries can now improve foam using these specific mechanisms rather than adjusting multiple factors simultaneously.

The GSA is letting AI chatbot makers jump the FedRAMP queue

The US government wants more AI chatbots in fed employees' hands, and its push to do so means that tech companies keen to provide other services will have to get in line behind the LLM makers.…
