Nuclear impulse could deflect massive asteroid

Lawrence Livermore National Laboratory

Researchers have completed the first-ever, in-depth investigation into how an asteroid would respond to a nuclear deflection attempt, finding that a nuclear device would be able to deflect an asteroid too massive for other approaches. The paper was published by Acta Astronautica on Oct. 15.

Sandia research focuses on ‘switching on’ iron in clay minerals

Sandia National Laboratories

Sandia National Laboratories researchers have discovered the mechanism to “switch on” iron residing in clay mineral structures, leading to the understanding of how to make iron reactive under oxygen-free conditions.This research will help scientists understand and predict how contaminants, such as arsenic, selenium and chromium, move through the environment and enter waterways.

Antiquated dams hold key to water quality

University of Delaware

Small, centuries-old dams are of no use to humans. But researchers will use NSF grants to examine whether removing them will harm water quality. Blocking the water makes soil upstream richer in carbon, which acts as an important filter of nitrogen, a key pollutant in our nation's waterways.

Scientists enhance color and texture of cultured meat

Tufts University

A team of Tufts University-led researchers exploring the development of cultured meat found that the addition of the iron-carrying protein myoglobin improves the growth, texture and color of bovine muscle grown from cells in culture. This development is a step toward the ultimate goal of growing meat from livestock animal cells for human consumption.

“I am multiracial”

University of Utah

According to new research from University of Utah psychologists Jasmine Norman and Jacqueline Chen, questions such as “What are you?” and other experiences of discrimination are related to mixed race people’s identification as multiracial, particularly if that discrimination comes from monoracial people with whom they share heritage, or includes comments that a person’s appearance doesn’t match their background.

Machine-Learning Analysis of X-ray Data Picks Out Key Catalytic Properties

Brookhaven National Laboratory

Scientists seeking to design new catalysts to convert carbon dioxide (CO2) to methane have used a novel artificial intelligence (AI) approach to identify key catalytic properties. By using this method to track the size, structure, and chemistry of catalytic particles under real reaction conditions, the scientists can identify which properties correspond to the best catalytic performance, and then use that information to guide the design of more efficient catalysts.

'Artificial leaf' successfully produces clean gas

University of Cambridge

A widely-used gas that is currently produced from fossil fuels can instead be made by an 'artificial leaf' that uses only sunlight, carbon dioxide and water, and which could eventually be used to develop a sustainable liquid fuel alternative to petrol.
