Summaries

Massive Stars Are Factories for Ingredients to Life

nasa.gov
  • Massive amounts of water and organic molecules, never before seen, discovered in swirling, disk-shaped clouds surrounding young stars.
  • Young stars are produce life-inducing molecules, and It probably also happened during the formation of the sun and the inner planets of our solar system.
  • It was discovered through infrared observations of NASA’s airplane telescope, which demonstrates the power of infrared observatories to find simple organic compounds.
  • Celestial clouds collapse into a rotating disc of gas and dust to form stars, the chemical soup of organic molecules was found in the inner regions of these discs.
  • Further studies of massive young stars will help scientists understand the processes creating organic molecules.

Microwaving plastic waste can generate clean hydrogen

newscientist.com
  • New method, quicker and less energy-intensive compared to alternatives, can recover 97% of hydrogen from plastic within seconds.
  • Scientists cut up plastic into small pieces, mixed it with a catalyst of iron oxide and aluminium oxide, and blasted it with a 1000 watt microwave generator.
  • The leftover solid material was carbon nanotubes.
  • So far it was only tested in experiments with 300 grams of plastic, but larger experiments are being planned.

Scientists find dopamine, serotonin have unexpectedly profound roles in the human brain

  • Traditionally linked to reward processing, dopamine and serotonin might have far greater roles in the human nervous system than previously known.
  • For the first time, moment-to-moment activity of dopamine and serotonin transmitter systems was measured, indicating that they’re involved in perception and cognition.
  • Using an electrochemical method, with a small carbon fiber microelectrode, researchers recorded neurotransmitter changes in five patients during brain surgery.
  • Many psychiatric and neurological disorders change how we absorb information, interpret it, and make decisions - dopamine and serotonin are key suspects.

Engineers print wearable sensors directly on skin without heat

news.psu.edu
  • Using ingredients from peelable face masks and eggshells, researchers were able to print sensors onto skin at room temperature.
  • It’s an ultrathin layer of metal patterns that can bend and fold without losing electromechanical capabilities.
  • The sensors can precisely and continuously capture temperature, humidity, blood oxygen levels, and heart performance signals.
  • It can be easily removed with a hot shower, and it can be reused.
  • Next, the sensors will be tweaked for monitoring specific symptoms of diseases like COVID.

Daydreaming at Work Can Fuel Creativity

journals.aom.org
  • We spend nearly half of each day daydreaming, and usually think that it’s a bad thing, but it turns out that highly demanding tasks make us daydream more.
  • It allows us to turn off our surroundings, and can be a way of imagining solutions to the problem at hand.
  • To find this out, researchers did two studies of employees and managers in South America, including mainly surveys about daydreaming.
  • Daydreaming turned out to happen more when the tasks required a lot of focus - it can boost creative problem-solving as long as we’re personally invested in our work.
  • However, for people who don’t identify with their work, daydreaming was linked to worse performance.
