Summaries

Young children have lower grades due to increased salt intake

news.nus.edu.sg
  • Children who live in households with high levels of salt in the water supply, are less likely to have good grades.
  • This is shown in a study that monitored young children’s school progress in Bangladesh.
  • The effect doesn’t occur in older children, suggesting that aging reduces the negative effects of salt consumption.

Single-cell organisms might be able to process information and make decisions

hms.harvard.edu
  • New single-cell organism characteristics found by scientists who looked where no one else bothered, and replicated a 100-year old experiment.
  • The non-funded side-project revealed that an organism called Stentor roeselii can make relatively complex decisions, it’s behaviours aren’t automatic.
  • This might mean that cells can process information and make decisions.

Kids with depressed parents have different brains

eurekalert.org
  • Analysis of brain images from over 7,000 children shows that kids who have a depressed parent also have a differently structured part of the brain.
  • Their right putamen (brain area linked to reward, motivation, pleasure) is smaller than in kids whose parents don’t have depression.
  • The children will be followed for 10 years, allowing scientists to study how this influences their development.
  • In particular, they can see if a smaller putamen leads to depression, or is a general factor for other mental diseases.

There are a million times more microplastics in oceans than we thought

ucsdnews.ucsd.edu
  • Previous estimates of the amount of microplastics in oceans has just been proven to be very, very wrong.
  • New study provides data that suggests 8.3 million pieces of microplastics per cubic meter of water, previous studies estimated 10 pieces per cubic meter.
  • It was discovered by analysing salps, jellyfish-like water creatures, and study authors found microplastics in all 100 samples.

Magnetic Quantum Computing Circuit doesn’t need any electricity

news.mit.edu
  • MIT researchers have made a magnetic circuit that generates 0s and 1s without any electrical input.
  • The device consists of layered nanofilms of magnetic materials, separated into two halves by a nanometer-wide wall.
  • It is a promising new approach to building quantum computers, one that requires only the natural magnetic properties of materials to work.
  • Researchers compare it to a water pipe, in which you can control how the spin wave (quantum property of electrons) moves across magnetic materials.
  • So far it’s not usable, but researchers are planning to build a working circuit and perform basic calculations with it, to see if the device is viable.
