There are 18 captive orcas in the US. Captive orcas can also show signs of chronic stress. Captive orcas can suffer a number of health problems including severe tooth damage. The history of releasing captive orcas in the USOnly one captive orca in the US has ever been released back into the ocean — Keiko, the orca who starred in the 1993 film "Free Willy." Captive orcas can't thrive in small tanks but may not thrive in the wild, either.

Neuroscientists explain how they keep healthy brains with regular exercise, enough sleep, and more. Keeping your brain healthy is important for delaying neurodegenerative conditions like Alzheimer's. But there's a lot more to keeping the brain healthy and the science behind it. Try new thingsExposing yourself to new people, places, and challenges can keep your mind sharp, improve brain plasticity and strengthen your brain, Shepherd said. "Your brain is not somehow totally separate from your body, so things that are helpful for your body are also good for your brain," Lerner said.

"I certainly think orcas are capable of complex emotions," Monika Wieland Shields, director of the Orca Behavior Institute told Insider. And yet, these situations haven't resulted in wild orcas attacking boats, Shields said. Orcas in captivity have attacked and killed humans, but there are no records of orcas killing humans in the wild. The orcas are trying to playAccording to Shields, orcas' natural curiosity and playfulness are likely the cause for these encounters and not revenge. According to Trites, orcas might simply enjoy the sensation of ramming into boats.

☆ Up to 1.7 billion T. rex dinosaurs lived on Earth, a new study found. But scientists aren't sure where all the bones went.

New calculations suggest that 1.7 billion T. rexes lived on Earth from 65.5-68 million years ago. This dichotomy between how many T. rexes lived and how few fossils we have of them shows us just how rare fossilization is and how much more we have to learn about these majestic creatures. Warpaintcobra/Getty ImagesMarshall was the lead author of an earlier study that estimated 2.5 billion T. rexes once roamed Earth. Of the roughly 1.7 billion, or so, T. rexes who roamed our planet, scientists have only uncovered a few hundred fossils, equating to fewer than 100 total dinosaurs. Despite their prime conditions for fossilization, if Giebeler's calculations are correct, scientists have only found about 0.0000002% of the T. rex that lived on Earth.

☆ Scientists discovered a surprising new brain circuit in mice that's making them rethink how humans may manage extreme stress

A newly discovered brain circuit in mice helps relax the brain during times of extreme stress. A lead researcher says the study results suggest similar processes may occur in the human brain. Mouse brains are, of course, different from human brains. A new brain circuitStressed-out mice may hold the key to better understanding stress and how we manage it. And because the newly discovered brain circuit in mice helps control attention and perception, it could play an important role in treating attention disorders, and other neurological and psychological disorders, Poskanzer said.

☆ A scientist scraped a black dot on his forehead and filmed it under a microscope, revealing dozens of crawling face mites

He saw dozens of tiny face mites, aka Demodex mites, crawling around on the plate. This is more common in people with weakened immune systems that can't keep the population of Demodex mites under control. You can't get rid of face mites, and you shouldn't want toBecause Demodex mites live inside your pores, it's nearly impossible to scrub them out, Robinson said. Our face mites are a testament to that. Check out more footage of these face mites in the video below:

Thissen said it's important to show the public these images. "It shows the reality, tragedy, and consequences of the nuclear disaster. It's not the first and will not be the last nuclear accident," he said. This chaotic scene may be the result of wild animals or perhaps it was made by people rushing to evacuate.

☆ Are left handed people more creative? Brain scans reveal why these individuals might be wired differently

In particular, they display less brain lateralization than right-handers, said Eric Zillmer, a professor of neuropsychology at Drexel University. Because lefties rely less on the left hemisphere, researchers describe this as displaying less brain lateralization, Zillmer said. Zillmer said these differences in brain lateralization may help left-handers think more outside the box and therefore have a more creative edge. "Our creative brain is utilized when we are engaging in new, unfamiliar experiences," Bajaj said. If you want to use your left hand more often, practice.

☆ What happens to the human brain during a near-death experience that can trigger vivid memories and bizarre spiritual encounters

But people who have had a near-death experience (NDE) typically report feeling peace, comfort, and calm throughout the ordeal. What a near-death experience feels likeNDEs can trigger a lot of peculiar sensations, including feeling like you're floating above your body or an out-of-body experience. What a near-death experience does to the brainThe temporal lobe, highlighted here, is responsible for language and visual memory, among other things. It might differ based on cultural or spiritual beliefs, but it is essentially the same," San Filippo said. "That leads us to believe that a near-death experience is a transpersonal experience happening outside of the brain."

We also wanted to give ourselves more wiggle room in our budget by lowering our monthly mortgage payment in case either of us lost our income. We were able to refinance to a new 3.4% 30-year loan to save $150 a month and more than $30,000 over the life of the loan. Why we decided to refinance nowWe bought our house in April 2017, using a 30-year mortgage at 4.4%. We decided to refinance not only to take advantage of lower mortgage refinance rates, but also as a precaution. A lower monthly mortgage payment gives us some flexibility and more cash flow if we find ourselves with less money coming in.
