Tissues of the brain frozen in a new solution for 18 months work perfectly after thawing

Scientists in China have developed a new chemical mixture that allows brain tissues to function again after freezing. The solution, made from methylcellulose, ethylene glycol, and other components, protects brain cells from damage during freezing and thawing. As a result, organoids retain their functions and structure even after 18 months of freezing and, overall, develop…

Not All Advanced Alien Civilizations May Escape Their Planets

Whether extraterrestrial civilizations and other intelligent beings exist remains unknown, though scientists have long speculated on this topic. In the mid-20th century, astrophysicist Frank Drake formulated an equation to estimate the number of extraterrestrial civilizations in the galaxy based on variables such as the number of sun-like stars, planets with suitable conditions, or the time…

Epigenetic Editing Potentially Lowers Cholesterol Levels Permanently

Scientists have presented the results of a remarkable preclinical study that employs an epigenetic approach instead of traditional gene editing. In this method, DNA sequences are not cut and replaced — instead, scientists merely adjust the activity of specific genes. This treatment has already led to the normalization of cholesterol levels in mice. Epigenetic editing…
