Fearless Fish

The effects of fishing are certainly not as extreme as the celestial impact that ended the age of the dinosaurs, but in some parts of the tropics we are getting close.

The predatory fish that have survived here have learned not to get suckered into chasing floating chunks of meat (AKA bait on hooks) and not to approach swimming bipeds, especially ones with pole spears. How the tables have turned! Way back in time, mammals became successful when a meteor hit our planet and the dinosaurs perished. We are seeing a similar transition on coral reefs, as the predators are removed and the prey fish gain capacity. The effects of fishing are certainly not as extreme as the celestial impact that ended the age of the dinosaurs, but in some parts of the tropics we are getting close.

Saying no is hard. These communication tips make it easy.

You can say 'no' to things, and you should. Do it like this.

Videos
  • Give yourself permission to say "no" to things. Saying yes to everything is a fast way to burn out.
  • Learn to say no in a way that keeps the door of opportunity open: No should never be a one-word answer. Say "No, but I could do this instead," or, "No, but let me connect you to someone who can help."
  • If you really want to say yes but can't manage another commitment, try qualifiers like "yes, if," or "yes, after."

Scientists reactivate cells from 28,000-year-old woolly mammoth

"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."

Yamagata et al.
Surprising Science
  • The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
  • Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
  • Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.

Why is 18 the age of adulthood if the brain can take 30 years to mature?

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.

Mind & Brain
  • Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
  • Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
  • The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
