All known life uses 4 DNA letters; UC San Diego showed an existing bacterial enzyme can accurately read and transcribe 8, doubling the genetic alphabet with synthetic letters
A researcher at a Chengdu university was bitten on the ring finger by a grass-green pitviper from Mount Emei at 22:15 on a September night, the swelling reached his elbow before he reached hospital, and the snake has now been named a species new to science, described partly from museum specimens collected in 1956 and from populations that had been identified as a more widespread relative on their looks alone
Author Lise Barnéoud on the bizarre and provoking world of microchimerism — when cells from one person live in another, genetically distinct individual
Why does a funnel-web spider new to science turn up at just three sites in northern Idaho, about 500 kilometres east of the western Cascades and coast ranges where its genus was known to live?
Life on Earth may have begun twice. A Science Advances study found that bacteria and archaea inherited one ancient genetic code but independently evolved the machinery needed to become free-living cells — leading the researchers to describe it as “one origin of the genetic code, but two origins of life.
AB Science reports completion of the step 3 of phase 1, evaluating the combination of AB8939 with venetoclax for the treatment of refractory or relapsed AML
