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.

Protein called REST could prolong life by limiting neuron excitement

  • Overexcited neurons lead to premature death, but a protein called REST appears to be the key to limiting the activity of neurons in the brain.
  • New study shows that people who live the longest have the most REST in their brains, but it’s unclear how exactly it prolongs their lives.
  • Earlier studies showed that people with neurodegenerative diseases like Alzheimer’s have low levels of REST.
  • The next steps are to find drugs that could boost REST, test them in lab organisms, and then test them in patients.

Opioid alternative discovered in mud

  • Lucky find leads scientists to a new type of molecule: bilaids.
  • They’re similar to endomorphins (they activate opioid receptors to relieve pain).
  • After chemical modifications, researchers arrived at bilorphin, which is as powerful as morphine.
  • Due to its’ unique characteristics, it could be an opioid alternative without the negative side-effects of opioids.
  • Also, since this new molecule was found in mud fungi, it might be a good idea to look for other unknown molecules in mud all over the world.

Antibody injection stops peanut allergy for 2 to 6 weeks, study shows

med.stanford.edu
  • New type of peanut allergy treatment could potentially be used to treat all food allergies in the future.
  • Study on 20 adults with severe peanut allergies shows that an antibody treatment, called etokimab, can stop a key molecule from activating the immune system.
  • Two weeks after just one injection, 11 people could eat a small serving of peanuts with no allergic reaction.
  • The treatment still has a lot of studies to go through before being approved.

To Survive in the Human Gut, Bacteria Need Genetic “Passcode”

hhmi.org
  • Studying the gut microbiome, scientists found that bacteria which protect us from toxins do so by inheriting immunity genes against those toxins.
  • In lab dishes and in living mice, transferring genes from a specific bacteria instantly immunised against that bacteria’s toxin.
  • Which means that all our microbiomes are different, and treatments targeting the microbiome need to be highly personalized.
  • Understanding how to do it will lead to better probiotic and live biotherapeutic treatments, which hold great promise as a way to battle sickness.
