  1. The pandemic dramatically affected many teens’ outlooks on life, yet some fared better than others, and scientists are eager to know why. Luckily, there was a large group of teenagers being studied through brain scans and surveys before the pandemic, and the research was continued throughout and after the pandemic. The scientists found a direct correlation between the connections in our brains and how we deal with stressful situations such as the pandemic. They plan to continue this research and find out if positive experiences can strengthen these connections in the brain to see if that helps prepare teens for stressful situations in the future.


  2. Scientists genetically engineered pig kidneys to more closely resemble the genetic makeup of human kidneys by singling out and eliminating certain sugars, transplanting them into a group of monkeys when finished. While monkeys with less human-like kidneys lived for an average of 24 days, those with comparatively more modified kidneys survived for over 100 days; the longest-living monkey lasted for over 2 years after receiving its kidney. Researchers hope that positive results in monkeys will pave the way for more genetically edited organs that will make up for the shortage of available organs for transplants.

  3. In many cases it is difficult to get X-rays because it is restrictive to lead, iron, and other dense metals. They then formulate another way to view fossils because they are so delicate. They used neutrons to scan it which gives a much clearer image compared to X-rays because they are stronger.

  4. Doctors are developing a device that can monitor a person’s brain activity and then administer the right drug dosage for each patient. Everyone is unique, and the right amounts of anesthetic help keep the patient asleep and painless. Adding more drugs than are needed or not giving enough could create serious problems. This new system focuses on reading brain waves and could help anesthesiologists during long surgeries.
