• How do plants make oxygen? Ask cyanobacteria

  30-03-2017 22:06
  
  The ability to generate oxygen through photosynthesis—that helpful service performed by plants and algae, making life possible for humans and animals on Earth—evolved just once, roughly 2.3 billion years ago, in certain types of cyanobacteria. This planet-changing biological invention has never been duplicated, as far as anyone can tell. Instead, according to endosymbiotic theory, all the "green" oxygen-producing organisms (plants and algae) simply subsumed cyanobacteria as organelle

• Proteins that can take the heat

  30-03-2017 21:04
  
  Ancient proteins may offer clues on how to engineer proteins that can withstand the high temperatures required in industrial applications, according to new research published in the Proceedings of the National Academy of Sciences. Researchers used experiments to examine critical differences between 15 proteins from the thioredoxin family, including seven extinct protein sequences that date back more than 4 billion years and were resurrected using ancestral sequence reconstructions.

• Waves on Sun give NASA new insight into space weather forecasting

  30-03-2017 20:11
  
  Our sun is a chaotic place, simmering with magnetic energy and constantly spewing out particles. Sometimes the sun releases solar flares and coronal mass ejections—huge eruptions of charged particles—which contribute to space weather and can interfere with satellites and telecommunications on Earth. While it has long been hard to predict such events, new research has uncovered a mechanism that may help forecasting these explosions.

• This timid little fish escapes predators by injecting them with opioid-laced venom

  30-03-2017 18:35
  
  Fang blennies are small fish with big teeth. Specifically, they have two large canine teeth that jut out of their lower jaw. Since blenny fish are only about two inches long, these "fangs" would be less than intimidating if not for the venom within. Blenny fish venom most likely causes a sudden drop in blood pressure in would-be predators, such as grouper fish, that have been bitten by blennies, researchers report on March 30 in Current Biology.
