Scientists discover life components in NASA asteroid sample.

summary

  • The NASA spacecraft returned to Earth from the asteroid Bennu in 2023.
  • The first detailed analysis of the material reveals organic molecules, including components of life.
  • This strengthens the theory that asteroids colliding with Earth may have provided life’s ingredients.

Scientists have found many organic molecules, including major building blocks of life, in a sample collected from distant asteroids.

Surprising discoveries suggest that the chemical components required for life may have spread throughout the early solar system.

NASA’s OSIRIS-REX SPACECRAFT was launched in 2016, gathering material from asteroids, dust, soil, and rocks, and returned them to Earth in 2023.

Analysis of the asteroid materials revealed in a sample published in Journal Nature shows that Earth’s life contains key organic compounds and amino acids.

Researchers did not find evidence of life on Bennu, but the results reinforce the theory that asteroids colliding with Earth may have provided life’s necessary ingredients.

NASA’s Scientific Mission Bureau stated that the OSIRIS-REX mission has already reshaped our understanding of life’s building blocks in the solar system.

The untouched samples collected from asteroids provide unique insights into the early solar system, unlike meteorites that may be contaminated.

The Bennu sample contains surprising concentrations of ammonia, an essential ingredient in biological processes.

Samples from Bennu also contain traces of minerals that are likely remnants of evaporated brine, suggesting complex compositions on the asteroid.

These discoveries on Bennu provide valuable insights into the complex composition of minerals and organic compounds that may have influenced the development of life in the solar system.

Further research is needed to fully grasp the implications of the Bennu samples for our understanding of life’s origins on Earth and other celestial bodies.

“Exploring the unique composition of Bennu and its implications for the emergence of life is a fascinating field of study that could shed light on the mysteries of life on Earth and beyond,” said Jason Dworkin, an OSIS-REX project scientist at NASA’s Goddard Space Flight Center.

Unveiling the key components that influence your microbiome and well-being

The rats in John Cryan's lab were withdrawn and anxious, behaving in ways that mirrored those who had been bullied at work and who feared they might encounter the bully again.

Believe it or not, the good news is that they fed some of these rodents a slurry of microbes extracted from their own feces. This may sound unpleasant, but it had a surprisingly positive effect on their behavior. “That was surprising,” says Cryan, a neurobiologist at University College Cork in Ireland. “We found that the behavioral changes that were induced by stress were normalized, and they started to behave like normal animals.”

Even more surprising, the mental changes weren't brought about by changes to gut bacteria, but by modifying another key aspect of the microbiome whose importance is only now being recognized: viruses.

After all, our bodies are full of these viruses – trillions of stowaways that do no harm to our health, but instead play a key role in nurturing a beneficial microbiome and making us healthier. Recent studies have found that the influence of this “virome” can be found throughout the body, from the blood to the brain. The hope is that tweaking it might lead to new ways of treating a variety of ailments, from inflammatory bowel disease and obesity to anxiety.

Microbiome Diversity

Over the past decade, there has been a surge in interest in the microbiome (all the tiny organisms that live on and in our bodies), but that interest has focused primarily on bacteria. Until recently, the assumptions were that…
