Breakthrough techniques in living cells upend field.

Two studies provide a radically new picture of how bacterial cells continually repair damaged sections (lesions) in their DNA.

Led by researchers from NYU Grossman School of Medicine, the work revolves around the delicacy of DNA molecules, which are vulnerable to damage by reactive byproducts of cellular metabolism, toxins, and ultraviolet light. Given that damaged DNA can result in detrimental DNA code changes (mutations) and death, cells evolved to have DNA repair machineries. A major unresolved question in the field, however, is how do these machineries rapidly search for and find rare stretches of damage amid the “vast fields” of undamaged DNA.

Scientists defrosted and analyzed 300 prehistoric worms from different ages and origins. Some came back to life.

Nearly two months after its debut at the Super Bowl, DeLorean Motor is inching closer to revealing itself to the public.

The Humble, Texas, electric-vehicle maker, which shares the name of the vehicle from the “Back to the Future” film franchise, started getting buzz after a 15-second spot during The Super Bowl this year.

Brig. Gen. Stephen Purdy: Seeing Starbase ‘gives you a lot of ideas of what the future could be’

COLORADO SPRINGS – Brig. Gen. Stephen Purdy was in Boca Chica, Texas, last month visiting Starbase. That is SpaceX’s launch and rocket manufacturing and testing facility where the company hopes to operate Starship, the largest rocket ever built.

Purdy is the commander of Florida’s Eastern Range and also serves as the Space Force’s program executive officer for assured access to space, a new post within the Space Systems Command overseeing launch services procurement for the U.S. military and intelligence agencies.

We live in the Milky Way galaxy, an immense, flat, spiral galaxy surrounded by a massive halo of stars and dark matter. The disk of stars, gas, and dust in which the Sun resides is fully 120,000 light years across; a soul-crushing distance on the human scale. In the middle of the disk is the central bulge, a lozenge-shaped hub of stars.

How did all this structure come together? We know it didn’t all happen at once, but what were the different chapters in the galaxy’s life? What is the timeline of the Milky Way?

NASA’s Kepler space telescope has spotted a Jupiter look-alike in a new discovery, even though the instrument stopped operations four years ago.

An international team of astrophysicists using NASA’s Kepler space telescope, which ceased operations in 2018, have discovered an exoplanet similar to Jupiter located 17,000 light-years from Earth, making it the farthest exoplanet ever found by Kepler. The exoplanet, officially designated K2-2016-BLG-0005Lb, was spotted in data captured by Kepler in 2016. Throughout its lifetime, Kepler observed over 2,700 now-confirmed planets.
