RNA gene scissors (CRISPR-Cas13) are gaining significant attention as a next-generation gene therapy with fewer side effects. They can suppress infection by eliminating viral RNA, such as in ...

Back to Article List Bennu isn’t likely to hit Earth — but if it did, here’s what would happen Although classified as a potentially hazardous asteroid, Bennu probably won't hit Earth.

Life on Earth relies on molecular building blocks to make DNA and proteins. Scientists have long wondered how prevalent these precursors were at the birth of our solar system. A sample of dust and ...

The 120 g of material came from the near-Earth asteroid 101955 Bennu, which OSIRIS-REx visited in 2020. The findings “bolster the hypothesis that asteroids like Bennu could have delivered the raw ...

Pristine samples of asteroid Bennu have revealed something entirely unexpected — not only does the asteroid contain the chemical building blocks of life, but it also originated from an ancient ...

NASA’s OSIRIS-REx mission delivered samples from asteroid Bennu, revealing crucial molecules linked to life, including amino acids and nucleobases found in DNA and RNA. The presence of ammonia and ...

Scientists from NASA’s OSIRIS-REx asteroid sample return mission recently delivered remarkable findings about asteroid 101955 Bennu after the mission returned its samples to Earth in 2023. While ...

This spacecraft rendezvoused with asteroid (101955) Bennu on December 3rd, 2018, returning 121.6 grams of material (the largest sample ever) to Earth by September 2023.

In addition to the 14 biological amino acids, the samples from Bennu also contained 19 more non-biological amino acids, as well as the five nucleobases that make up RNA and DNA.

NASA's asteroid samples from Bennu hold not only building blocks for life, including amino acids and all five DNA and RNA nucleobases, but also the salty remains of an ancient water world ...
