  • In November 2018, a Chinese scientist claimed he'd flouted ethics and the law to edit genes in human embryos.
  • Other Chinese scientists call He Jiankui's research "crazy."
  • Three gene-modified babies are now living in China, future uncertain.

  • There is a growing understanding in the medical community of how important the immune system is for our mental health.
  • Much of the risk for mental illness is due to heritability, but a large portion of that risk is also due to the environment.
  • Since children are often exposed to pet dogs at a young age, it could be that their presence affects developing children's immune systems; new research on over a 1,000 study participants suggests that this may indeed be the case.

  • Researchers recently uncovered a piece of chewed-on birch pitch in an archaeological dig in Denmark.
  • Conducting a genetic analysis of the material left in the birch pitch offered a plethora of insights into the individual who last chewed it.
  • The gum-chewer has been dubbed Lola. She lived 5,700 years ago; and she had dark skin, dark hair, and blue eyes.

'One among millions': DNA is not the only genetic molecule

A recent computer analysis found that millions of possible chemical compounds could be used to store genetic information. This begs the question — why DNA?

  • The central dogma of biology states that genetic information flows from DNA to RNA to proteins, but new research suggests that this may not be the only way for life to work.
  • A sophisticated computer analysis revealed that millions of other molecules could be used to function in place of the two nucleic acids, DNA and RNA.
  • The results have important implications for developing new drugs, the origins of life on Earth, and its possible presence in the rest of the universe.
