New research indicates that paternal mice that physically interact with their offspring grow new brain cells and form lasting memories of the babies.
Researchers have discovered that paternal mice that physically interact with their babies grow new brain cells and form lasting memories of their babies. Scientists determined that when paternal mice interact with their newborn babies, new brain cells develop in the olfactory bulb—the part of the brain responsible for sense of smell, and in the hippocampus, which is responsible for memory. Weeks after the fathers are separated from their babies, they can still recognize their offspring from unrelated mice. The study may have implications for long-term mental health.
The findings are based on a phenomenon known as the "Mighty Girl Effect."
- The study tracked the responses of more than 5,000 men over the course of a decade.
- The results showed that men who lived with daughters were less likely to hold traditional views on gender relations and roles.
- This effect seemed to be strongest as the daughters entered secondary-school age.
There might be hope for our oceans, thanks to one clumsy moment in a coral tank.
- David Vaughan at the Mote Laboratory is growing coral 40 times faster than in the wild.
- It typically takes coral 25 to 75 years to reach sexual maturity. With a new coral fragmentation method, it takes just 3.
- Scientists and conservationists plan to plant 100,000 pieces of coral around the Florida Reef Tract by 2019 and millions more around the world in the years to come.
The billionaire entrepreneur predicts the rise of technology will soon force society to rethink the modern work week.
- Branson made the argument in a recent blog post published on the Virgin website.
- The 40-hour work week stems from labor laws created in the early 20th century, and many have said this model is becoming increasingly obsolete.
- The average American currently works 47 hours per week, on average.
