As a boy, Francisco Ramirez Cruz loved hiking with his grandfather up into the mountains of central Mexico. While the old man grazed sheep or hunted for wild mushrooms, Ramirez would play amid the throngs of monarch butterflies that migrated 3,000 miles to this forest each autumn, turning the blue sky into a sea of orange. In the middle of Ramirez’s orchard of apple and plum trees, the scientists helped him construct a small greenhouse, where he tends to several dozen saplings that were taken from the forest and will eventually be replanted.

Nutrition experts like to point out why people on low-carb or no-carb diets might feel more awake throughout the day: Glucose is the brain’s chosen fuel, and it typically gets it from carbs and sugar. “The best thing is to understand that for your brain to feel clear, you need to cut down on the sugars, your gut needs to be happy, and you need to have a nutrient-rich diet,” says Dr. Eva Selhub, a former instructor at Harvard Medical School who now runs her own wellness consultancy. In the keto and carnivore diets—as in Woo’s fasting diet—the body uses fat as its energy source instead, converting it into liver-produced chemicals called ketones, which the brain can also use as fuel.

The Event Horizon Telescope, an international array of observatories teaming up to form a virtual, Earth-sized telescope in the hopes of capturing the first real image of a black hole, held six simultaneous press conferences across the globe today — and what those conferences announced did not disappoint. It’s actually 100 billion kilometers across, and what we’re looking at — that dark spot surrounded by the orange-red ring — is the “shadow” created by the black hole’s event horizon, the point where gravity is so intense that light cannot escape. We’ve observed one, we can study it and, hopefully not long from now, we’ll know even more about black holes than we’ve been able to piece together without having seen one.

It was at a charity that helped local people find employment that someone first mentioned the term “food bank” to Wright. She was terrified that, should she seek help at a food bank, social services would take her children away. The Royal College of Paediatrics and Child Health and the Trussell Trust are among those concerned about how food insecurity may be affecting children’s health.

Today many scientists who study aging will tell you that people are still looking at longevity in the wrong way. According to Sinclair, that’s partly because currently available drugs are developed to target what he describes as “symptoms of aging,” which include diseases like cancer and heart disease. “People are skeptical that you can change both a person’s healthspan and their life span,” says Dr. Nir Barzilai, director of the Institute for Aging Research at the Albert Einstein College of Medicine and a medical adviser for Life Biosciences.

Some of it was lost to space (Mars doesn’t have a magnetic field to protect it from solar wind), some of the water reacted with volcanic rocks and then got trapped in minerals, and some of the water is still there today, frozen into the ice caps and in permafrost layers below the ground. Professor, Astronomy, Vanderbilt University, and the author of ‘Life on Mars,’ from which the below is drawn

If we take all the water on a planet, put it on the surface of the planet, and spread it out evenly over 100% of the surface area, we would have what planetary scientists call a ‘global ocean.’ However, if, in addition to the evidence from atmospheric gasses, we use the visual evidence for flowing water on the surface of Mars, which is clear in the form of dried up river valleys and outflow channels that scar the ancient surface of the red planet, we can estimate that Mars once had enough water to generate a global ocean with a depth of 1,500 to 3,000 feet.

Now, a team has used a type of artificial intelligence to confirm the existence of a bizarre new state of matter, one in which potassium atoms exhibit properties of both a solid and a liquid at the same time. The computer models confirmed that between about 20,000 and 40,000 times atmospheric pressure and 400 to 800 Kelvin (260 to 980 degrees Fahrenheit), the potassium entered what’s called a chain-melted state, in which the chains dissolved into liquid while the remaining potassium crystals stayed solid. Now that the chain-melt phase of potassium is confirmed, it joins the known array of other unusual states of matter beyond gas, liquid, and solid.

The promo for the rebrand, rolled out across social media and TV spots, features a medley of Discovery scenes, stars, and bad-ass nature shots, set to the Blue Swede song Hooked on a Feeling. The full version of the campaign promo does contain a couple (literally, a couple) women, but overall the whole thing is a meaty shot of testosterone. Inspired by the Discovery rebrand, a group of incredible female researchers have put together their own catchy promo, and we can’t stop watching.

Last May, an elderly man was admitted to the Brooklyn branch of Mount Sinai Hospital for abdominal surgery. A blood test revealed that he was infected with a newly discovered germ as deadly as it was mysterious. The man at Mount Sinai died after 90 days in the hospital, but C. auris did not.

Here’s what the rover saw on March 26, as the Martian moon Phobos crossed the face of the sun. The image of Phobos was taken with Curiosity’s Mast Camera, with a special solar filter attached (kind of like the solar eclipse glasses you’d use to look at the sun on Earth). The Martian moon Phobos’s orbit is nearly directly over its equator; our moon, on the other hand, is in a tilted orbit, so the Earth, sun, and moon don’t line up as often.
