Natural starshades would help astronomers image exoplanets

In the past few decades, the study of extrasolar planets has grown by leaps and bounds, with the confirmation of over 4000 exoplanets. With so many planets available for study, the focus of exoplanet researchers is shifting ...

How a gooey slime helps bacteria survive

Bacteria have the ability to adapt to their environment to survive the host's immune defense. One such survival strategy includes the formation of a biofilm that prevents the immune system or antibiotics from reaching the ...

Hubble peeks at stellar treats

Looking its best ever is the star cluster NGC 2203, here imaged by the NASA/ESA Hubble Space Telescope. Aside from its dazzling good looks, this cluster of stars contains lots of astronomical treats that have helped astronomers ...

Calculating the benefits of exascale and quantum computers

A quintillion calculations a second. That's one with 18 zeros after it. It's the speed at which an exascale supercomputer will process information. The Department of Energy (DOE) is preparing for the first exascale computer ...

Scientists discover ancient enzymes evolve new tricks

Plants, herbivores, and pathogens are locked in a war for survival that is hundreds of millions of years old. Rooted in place and with no way to run, plants evolved complex, chemical-producing machinery in their cells to ...

Mitochondrial metabolite mediates longevity through epigenomes

In a study published in Science Advances, researchers from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences revealed that mitochondrial metabolite acetyl-CoA links mitochondrial stress ...
