Polar Bear vs. Grizzly Bear
Climate change is steering grizzly bears and polar bears on a collision course. When they meet in the middle, fights are inevitable. Find out who is favored to win, evolutionarily speaking.
It's long been shown that the rapidly warming earth is bad news for polar bears. Their habitat is shrinking, as are their food sources and breeding grounds. If global warming continues, they may face a tough competitor. Grizzly bear habitat is limited by frigid winters and sheets of ice. As their world warms up, they're expanding north. The habitats of the two predators are already beginning to overlap. If they continue to do so, the polar bears, not the grizzlies, are going to be the losers in the competition for survival. This is surprising to some. Grizzlies are just a frighteningly-named subspecies of brown bear.

Rediscovering the principles of self-actualisation might be just the tonic that the modern world is crying out for.
Abraham Maslow was the 20th-century American psychologist best-known for explaining motivation through his hierarchy of needs, which he represented in a pyramid. At the base, our physiological needs include food, water, warmth and rest.
"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."
- 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.
Does believing in true love make people act like jerks?
- Ghosting, or cutting off all contact suddenly with a romantic partner, is not nice.
- Growth-oriented people (who think relationships are made, not born) do not appreciate it.
- Destiny-oriented people (who believe in soulmates) are more likely to be okay with ghosting.
