- 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.
- 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.
- 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.
- 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.
- 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.
