Prebiotic amino acids bind to and stabilize prebiotic fatty acid membranes
  • New clues to the origin of cells on Earth found by adding amino acids to protocells that self-assembled from fatty acids.
  • Fatty-acid protocell membranes are stabilized after adding amino acids, and become fertile ground for basic life.
  • As the substances bond, they create molecular building blocks which eventually may have aided the formation of proteins.

Apples, tea and moderation – the 3 ingredients for a long life
  • Analysis of diet, cancer and health data collected from 53,048 Danes over 23 years, shows that flavonoid-rich foods reduce risk of heart-disease related death.
  • It’s important to consume multiple flavonoid-rich foods -- like tea, apples, oranges, blueberries, and broccoli.
  • The strongest health benefits were noticed in people at risk of chronic diseases due to smoking and drinking alcohol.
  • Though it helps ease the symptoms, the best way to avoid the dangers of smoking and alcohol is still not to indulge.
  • Only an association was found -- the exact nature of how flavonoids generate these health benefits are unknown.

Neurologists Pinpoint Which Strange Sleeping Patterns Run in the Family
  • Study of 2,422 sleep clinic patients shows that 1 in every 300 people might be genetically predisposed to wake up early in the morning.
  • These people have strict sleeping schedules, and feel more awake than others when they first wake up.
  • Those who don’t sleep at night, due to work or differences in circadian rhythm, are at bigger risk of health and sleep issues.
  • Study author says that the healthiest approach would be to listen to one’s body clock, and organize sleep in sync with our biology.

Solar energy becomes biofuel without solar cells
  • Researchers have produced microorganisms that can efficiently create butanol using only carbon dioxide and solar energy.
  • They are cyanobacteria built to specialise in producing energy, developed with the help of synthetic biology and genetic modifications.
  • Cyanobacteria are the most efficient photosynthetic organisms on Eearth.
  • The modified bacteria is efficient enough that it could be used to produce fuel, or components for tyre rubber.
  • It could also potentially be used in industries with large greenhouse gas emissions to significantly reduce them.

Ultra-thin Layers of Rust Generate Electricity from Flowing Water
  • Graphene phenomenon - the electrokinetic effect - discovered in rust, as it can convert kinetic energy of saltwater into electricity, without any chemical reaction.
  • It would be difficult to fabricate graphene films, but it’s much easier to make layers of rust on iron, which would make it a valid method for generating electricity.
  • To form a consistently thin layer, researchers used physical vapor deposition to turn iron oxide into a vapor that condensed on the desired surfaces.
  • Various concentrations of salt water generated several tens of milivolts and several microamps per square cm.
  • 10 sq meters could generate enough power for a standard US home, but short-term less demanding uses are more likely, like low-power devices in remote locations.
