It's been nearly a year since former Fox News host Megyn Kelly was released from a lucrative contract with NBC after the television personality questioned whether or not blackface is appropriate on Halloween (it's not).

Judging from a recent tweet, it looks like Kelly wouldn't find it challenging to step back into her role as one of the most prominent faces of Fox News.

The renowned British scientist Stephen Hawking died in 2018, but he’s still talking to us. His parting words to humanity have just been released, in the form of recorded excerpts from his last book, Brief Answers to Big Questions. Here’s what he has to say.

First, we have to stop ignoring climate change or we will be doomed, said Hawking. “A rise in ocean temperature would melt the ice caps and cause the release of large amounts of carbon dioxide,” Hawking said. “Both effects could make our climate like that of Venus with a temperature of 250C.”

We expect to encounter the beauty of nature at the beach, but too often instead beachgoers encounter trash, pollution, and excessive development on the world’s shorelines. A growing number of sand artists want to show another way humans can leave their mark on the beach: Temporarily. Sand artists create stunning works of art designed to dissolve in the oceans’ tides.

Visitors to the Welsh Pembrokeshire Coast in Britain might encounter artist Marc Treanor’s astonishing works of art — if they time their visit to the beach just right. Pembroke’s enormous, ornate sand carvings, which he creates simply by raking the sand, take hours to create and last just a few hours. They require no toxic materials, consume no resources, harm no species, and will never require disposal.

Rebuilding after Hurricane Michael could cost upwards of $4.5 billion. That’s nothing: Hurricane Florence is estimated to cost $50 billion. Hurricane Harvey cost $125 billion. In 2017, 16 separate weather events in the U.S., three of which were the costliest storms on record, cost a cumulative $306.2 billion. Who pays? We all do, in the form of tax dollars and higher insurance premiums. As climate change accelerates and sea levels rise, those costs will only continue to break records and weigh upon society.

Some people are questioning the sense of pouring billions into rebuilding efforts in zones that will be targeted again, or that are predicted to be underwater entirely as climate change advances. The Union of Concerned Scientists calculates that 300,000 coastal homes are located in areas that will experience chronic flooding or be underwater in the next 25 years.

For as many as 90 percent of all pregnant women, morning sickness is an expected part of the gestational experience. This period of nausea and vomiting is not just limited to the morning and it’s not exclusive to the first trimester of pregnancy, contrary to popular belief. It’s unknown exactly what causes it, although some doctors believe it may be a reaction to the pregnancy hormone. For most women, it’s deeply unpleasant but manageable.

For a few, however, it can be devastating or even deadly. Morning sickness can be so violent and severe that a woman might vomit as much as fifty times a day, in a severe complication of pregnancy known as hyperemesis gravidarum. This condition, which affects up to 3 percent of pregnancies, leads to dehydration and starvation, endangering her wellbeing as well as that of the fetus.

As the planet heats up, glaciers are melting at a catastrophic rate. Colombia's glaciers have lost a third of their mass since the mid-1990s and are expected to be gone in 30 years. Glacier National Park in Montana was named for the 150 or so glaciers present when it was established in 1910, but today it has fewer than 26. Researchers believe that most central and eastern Himalayan glaciers will be gone by 2035. The largest glacier in Greenland has lost more ice in the last 15 years than it did in the previous 100, and scientists predict that when all of Greenland’s ice is gone, sea levels around the world will rise 20 feet.

“The changes we are witnessing are amazing,” says Eric Rignot, a professor at The University of California, Irvine and a senior scientist on a NASA team that’s traveled to Greenland to try to better understand exactly how quickly its glaciers are melting. “None of us expected to see such changes in Greenland.”

Humans have long envied fish their ability to breathe underwater. A few extreme athletes trained in the sport of freediving—in which divers swim underwater or perform aquatic feats on a single breath—have been able to hold their breath for more than 20 minutes. (The current world record is held by Croatian free diver Budimir Šobat, who held his breath while staying underwater for 24 minutes, 11 seconds in February 2018.) But that’s not breathing underwater.

So envious are we, in fact, that it shouldn't surprise us that there have been songs written about this elusive phenomenon.
