Effectiveness of Surgical and Cotton Masks in Blocking SARS–CoV-2: A Controlled Comparison in 4 Patients
  • New study, done by South Korean scientists, shows that “neither surgical nor cotton masks effectively filtered SARS–CoV-2 during coughs by infected patients.”.
  • Even though previous research shows these masks were effective for influenza, they are not an effective way to stop the spread of COVID.
  • Scientists don’t know yet how much of the virus is transmitted during coughing.
  • It’s worth noting, that the COVID contamination was actually bigger on the outside of the masks, than on the inside.

The growth of an organism rides on a pattern of waves
  • Close observation of starfish eggs (which are similar to many other animal eggs) shows that fertilization causes a specific pattern of spiral waves on the egg surface.
  • It is the universal wave pattern, which also occurs in quantum fluid vortices, atmospheric and oceanic circulations, and electrical signals in the heart and brain.
  • These waves move around proteins which work together to find the center of the egg, and organize cell division around the egg’s core.
  • This finding could be beneficial to quantum computing, since the protein waves distribute cell division signals, maybe waves could be used for quantum data.
  • Study authors collected 10 starfish eggs, introduced a hormone to stimulate maturation, observed through a confocal microscope.

New protein could be used to selectively repair DNA strands
  • New protein—TEX264—could help us reverse DNA damage, and help cure neurological diseases, cancer, and aging side-effects, scientists say.
  • TEX264 is kind of sticky, it sticks to other enzymes and together they can destroy toxic proteins that cause DNA damage.
  • It is a very complex study and it’s still in early stages, but TEX264 already shows a lot of promise, according to study authors.
  • The ultimate goal is to selectively repair damaged DNA strands, and a lot more work needs to be done to reach that goal.

New type of electron behaviour discovered in crystalline materials
  • New behaviour of electrons discovered, in which they stop bouncing around, and form a specific pattern.
  • It was discovered while experimenting with stacking few-atom-thick 2-D materials, and it happens in room temperature conditions, which was presumed impossible.
  • These materials are made of repeating patterns of atoms, forcing electrons to only move in two dimensions.
  • The behaviour results from a mix of physical and quantum mechanical factors, guiding electrons to form in specific places, in a repeatable pattern.
  • So far, scientists still don’t fully understand it, and will need to study it a lot more in order to potentially harness it to use in electronics.

Study shows, for the first time, that giving Oxytocin to men with autism can have lasting positive effects
  • Scientists tested Oxytocin on a group of 40 adult men with autism (half of them were given placebo).
  • First, the team tested how much Oxytocin the men’s bodies produced.
  • Secondly, the men were given Oxytocin (in nasal spray) for four weeks.
  • This generated positive effects (less repetitive behavior, easier relationship forming) for up to a year after receiving the Oxytocin.
  • But this study is just the first step, a lot more studies will have to be performed before Oxytocin is used in a drug for autistic patients.
