DNA Mutations Do Not Occur Randomly – Discovery Transforms Our View of Evolution

Genetic Mutations Concept

Beating the Odds in Mutation’s Game of Chance Discovery that plants protect their most essential genes transforms our view of evolution. Mutations of DNA do not occur as randomly as previously assumed, according to new research from Max Planck Institute for Biology Tübingen in Germany and University of California Davis in the US. The findings … Read more

Producing Clean Hydrogen From Solar Power and Wood Chips

Proposed facility design for solar-powered zero-carbon emission hydrogen production. Credit: KyotoU/Shutaro Takeda In the global race to curb climate change and reduce carbon emissions, hydrogen is considered a serious contender to replace fossil fuels. Although hydrogen ‘burns’ cleanly, with only water as a by-product, the current way of making hydrogen a reliable fuel alternative is … Read more

More Than Meets the Eye

By European Space Agency (ESA) January 16, 2022 Credit: ESA/Roscosmos/CaSSIS, CC BY-SA 3.0 IGO There’s more to this image of Mars than first meets the eye: nestled in the detail of the cliff face that cuts through this scene are signs of geology in motion. Zooming in reveals several boulders that have fallen from the … Read more

Physics-Based Engineering and the Machine-Learning “Black Box” Problem

AI Machine Learning Mystery Concept

By Mary Beth Gallagher, MIT Department of Mechanical Engineering January 16, 2022 In MIT 2.C161, George Barbastathis demonstrates how mechanical engineers can use their knowledge of physical systems to keep algorithms in check and develop more accurate predictions. Machine-learning algorithms are often referred to as a “black box.” Once data are put into an algorithm, … Read more

Burst of Rain Causing Problems After Months of Severe Drought

Burst of Rain Causing Problems After Months of Severe Drought

By Adam Voiland, NASA Earth Observatory January 16, 2022 December 14, 2021 January 7, 2022 After months of severe drought, a burst of rain is causing problems. For much of 2021, drought gripped southern Iran, parching crops, drying wells, and fueling protests over water. The first week of 2022 brought the opposite problem—a series of potent rain and … Read more

In Down Syndrome Cells, Genome-Wide Disruptions Mimic a Senescence-Like State – Points to Potential Treatment

Neural Progenitor Cells

Neural progenitor cells with the typical number of chromosomes show significant outward migration in culture (top). The cells in the bottom left are untreated trisomy 21 cells. On the bottom right are cells treated with anti-senecence drugs, which restored migration.
