Imagine applying for the top colleges in the United States hoping to get accepted to at least one.Well, that was the least of Mekhi Johnson's worries when applying for colleges this year. The Baltimore senior said that at six years old he heard a story on the radio about a student who was accepted to all of the Ivy League schools and knew that was his goal."I'm going to do that one day," said Johnson.And on 'Ivy Decision Day' he learned that he finally made it a reality. Johnson, who attends the Gilman School in Batlimore, serves as the President of the Diversity Council, a member of the school's acapella group, school band, and an avid volunteer, all while being a National Merit Scholarship Program Commended Student with a 98.1 average.More than 280,000 applicants applied to Ivy League schools last year. Out of that number, less than five of them were able to achieve acceptance by all eight colleges. Johnson is not only a 'goal getter' but he's the first Gilman student to achieve this distinction of acceptance.   1072

I will be leaving the great Walter Reed Medical Center today at 6:30 P.M. Feeling really good! Don’t be afraid of Covid. Don’t let it dominate your life. We have developed, under the Trump Administration, some really great drugs & knowledge. I feel better than I did 20 years ago!— Donald J. Trump (@realDonaldTrump) October 5, 2020 344

Hurricane Lane may have passed by the island chain over the weekend, but Hawaii is still feeling the storm's aftereffects as residents recover from days of heavy rain and remain on the lookout for even more showers.Lane dropped 52.02 inches of rain on Hawaii from August 22-26, the second highest rainfall total from a tropical cyclone in the US since 1950, according to preliminary data from the National Weather Service (NWS).That's behind only the 60.58 inches dumped on Nederland, Texas by Hurricane Harvey last year.Hawaii's Big Island -- the easternmost island in the chain -- was hammered hardest by rain. Some residents there had to be evacuated, with water rescues occurring in Hilo and Keaau, the NWS said. A number of roads were closed by flooding and landslides. 782

If you're interested in fish who are scary-looking, poisonous and chock-full of elaborate defense mechanisms, look no further than the stonefish, a genus of fish that populate coastal waters of the Indo-Pacific region.As if their deadly venom and spiny exteriors weren't enough, scientists at the University of Kansas have found that stonefish also have a hidden switchblade on their face that they can flick out whenever they feel like they're in danger.Scientists call the bony, blade-like protrusion a "lachrymal saber," because it is located on a bone under the fish's eyes. Also, "lachrymal saber" is just a really metal-sounding name.William Leo Smith, associate curator and associate professor of ecology & evolutionary biology at KU, first started to understand how the lachrymal saber worked 15 years ago, when he was dissecting a stonefish he kept as a pet.This is a game-changerHe tells CNN the mechanism isn't just a cool new discovery (although it's that, too). It also changes the scientific understandings and classifications of this particular type of fish."It opens up these ideas of ecological questions. Muscular systems, bone systems, nervous systems all came together to form this. What led to its evolution or use?In other words, he says, "Why do we see this accumulation of so many horrible things on one fish?"The lachrymal saber is housed inside the fish's head, and they use their cheek muscles to deploy it. Though some stonefish are venomous, the saber is not.It could be a sex thing, tooSmith says he and his fellow researchers have reason to believe the saber isn't just for warding off predators: It could be a sex thing, too."There is evidence pushing towards that," he says. "They may use this in battles with other members of their species, like ram horns. It may also be involved in courtship behaviors."Oh, and the sabers glow."It's fluorescent green," Smith says. Since stonefish rely on camouflage for both protection and hunting prey, Smith doesn't think the fluorescence has a defensive purpose like, say, warning off predators.There are 134 described species of stonefish, and by Smith's observation, all of them have some form of lachrymal saber.  2202
