- Growing your own food could lower your carbon footprint by 3-5%.
- In recent years, we have acquired the ability to measure biological age: your chronological age does not necessarily match your biological since some people age faster. We measure biological aging with gene expression. Researchers found that an eight-week program of diet, exercise, and meditation could reduce biological age by two years. The study was small and short.
- You may have heard that younger and older people are happier, with middle-aged people reporting less happiness. Kratz suggests that such studies might not have been methodologically sound.
- Our brain is not good at producing new neurons. However, we have a rather abundant supply of another brain cell, astrocytes. Researchers took astrocytes and converted them into fully functional, integrated neurons (in mice). (Source: Nature)
- A beer might produce between 200,000 and 2 million bubbles before going flat.
- We now have the technology to edit your genes, or the genes your babies. CRISPR-Cas9 allows us to edit individual genes in a cell. But editing genes might often be unnecessary for medical purposes: it might suffice to silence or express the gene. Researchers have come up with a new technique called CRISPRoff which might do just that.
- The USA is approving the use of drones over people and at night.
- Omega 3 supplements may lower inflammation and boost repair mechanisms. (Source: Nature)
- You may finally have an effective vaccine against Malaria.
- It appears that bimekizumab might be a remarkably effective drug against psoriasis or other related diseases.
- New anti-depressants appear to increase suicide risks among teenagers.
- When seeking venture capital, female and Asians entrepreneurs may have slightly more luck with investors.
- As your cells divide, it is believed that small mutations are introduced. Recent research suggests that even cells that never divide may mutate.
- Adult mammals heal from injuries by forming scars. A new drug may prevent scars. It works in mice.
- Worms live longer when they have less food. It appears that smelling food is enough to make this effect go away. (Source: Nature)
- Reducing your blood pressure is always a good thing.
