Scientists Reverse the Aging Clock: Restore Age-Related Vision Loss Through Epigenetic Reprogramming

Proof-of-concept study represents first successful attempt to reverse the aging clock in animals through epigenetic reprogramming. Scientists turned on embryonic genes to reprogram cells of mouse retinas. Approach reversed glaucoma-induced eye damage in animals. Approach also restored […]

Gene engineers make super-size plants that are 40% larger – MIT Technology Review

Researchers hope to create a new “green revolution” by improving photosynthesis.

Genetic engineers in Illinois have designed tobacco plants that grow as much as 40% larger than usual. If similar changes can be made to soybeans or potatoes, it could increase food supplies—though you won’t see the new plants in fields for many years.

Heavy multitaskers have reduced memory

The smartphones that are now ubiquitous were just gaining popularity when Anthony Wagner became interested in the research of his Stanford colleague, Clifford Nass, on the effects of media multitasking and attention. Though Wagner, a professor of psychology at Stanford University and director of the Stanford Memory Laboratory, wasn’t convinced by the early data, he recommended some cognitive tests for Nass to use in subsequent experiments. More than 11 years later, Wagner was intrigued enough to write a review on past research findings, published in Proceedings of the National Academy of Sciences, and contribute some of his own.

Investigators searched a million people’s DNA to find Golden State serial killer – MIT Technology Review

Investigators may have compared a serial killer’s DNA with that of one million unwitting genealogy enthusiasts as part of an investigation that led to the arrest earlier this week of a man accused of being California’s elusive “Golden State Killer.”

The first “social network” of brains lets three people transmit thoughts to each other’s heads – MIT Technology Review

BrainNet allows collaborative problem-solving using direct brain-to-brain communication.

In recent years, physicists and neuroscientists have developed an armory of tools that can sense certain kinds of thoughts and transmit information about them into other brains. That has made brain-to-brain communication a reality.
