Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
In the 1980s, as tanning beds became a craze, melanoma rates began to climb. Since cancer often takes time to develop deaths due to melanoma peaked in 2013 but thanks to immunotherapy, less risky behavior, and earlier detection, rates dropped 18 percent within three years after.This is a fantastic public health victory. People still die, but that is from metastatic melanoma, the aggressive form that spreads from the skin to other organs, such as the lung, liver, or brain.
Social bonding in vampire bats is no surprise, they have roommates. What is uncommon is that they demonstrate behavior some might call friendship; unrelated vampire bats engage in social grooming and food sharing to form life-saving bonds that can last a lifetime. Vampire bats sustain themselves on only blood, and if a bat is unable to feed for 3 days, it runs the risk of starving. Like early man, they have a 'boom and bust' foraging lifestyle, so they either hit it big and get a large blood meal or they're starved for that night. If they starve three nights in a row there is a high chance they'll die but vampire bats with close social ties can be rescued from the brink.
An ancient Elpistostege fish fossil has revealed how the human hand evolved from fish fins, the missing evolutionary link in the 'fish to tetrapod transition', as fish began to foray in habitats such as shallow water and land during the Late Devonian period millions of years ago.
A new review finds a dramatic increase in the abundance of a worm that can be transmitted to humans who sushi - 283-fold more since the 1970s But is that due to better detection or a real increase? And what implications does it have for humans and marine mammals?
The oldest fossil of a modern bird yet found dates from the age of dinosaurs and was found in a limestone quarry near the Belgian-Dutch border, making it the first modern bird from the age of dinosaurs found in the northern hemisphere.
If the kids are out of school and missing homework, or you're tired of them playing Fortnite, here are seven fun projects they can get involved with courtesy of the National Science Foundation.1. Use on-the-go science tools to explore the world around you (all ages)Foldscopes are paper microscopes that give you a deeper look at the world around you. Peer at the cell structure in an onion's skin, examine a human hair or look at the busy microbial world of pond scum.2. Become a citizen scientist and help collect and analyze data for scientific research (all ages).
Soft robotics is a newer field, so no one is quite sure what to do with them, but sturdy softness could be useful in homes and workplaces where traditional robots could cause injury. Since they are squishy, they could be tools for disaster response.For now, they may play basketball. Or at least pick one up. Maybe eventually they will be a delightful companion that can still get down to business like Baymax from the Big Hero 6 cartoon and comics.
A vegetarian diet is promoted as beneficial to heart health and even the environment in more advocacy-based studies, but as its popularity has grown images of thin beautiful people are being supplanted by reality of just as many obese people as in a conventional diet.A vegetarian diet can't perform miracles, it's still about calories.
Your ears enjoy music but your heart may also benefit, according to a new study presented at the American College of Cardiology's Annual Scientific Session.Patients with early post-infarction angina, episodes of chest pain after a heart attack, reported significantly lower levels of anxiety and pain if they listened to music for 30 minutes a day. While that's hard to pin down biologically, 700,000 people survive a heart attack just in the U.S. each year and roughly 1 in 9 heart attack survivors experience subsequent episodes of chest pain and anxiety within the first 48 hours, so whatever works to reduce that.
We haven't had a widespread flu problem since 2018. Yet despite it only being 2020, some insist this year's coronavirus must be the product of government scientists, though some also suggest it was the result of 5G cellular service in Wuhan. Then China claimed it might be the U.S.What is the truth?The novel SARS-CoV-2 coronavirus that emerged in the city of Wuhan is the product of natural evolution, finds an analysis of genome sequence data from SARS-CoV-2 and related viruses published today.
Stegosaurs are among the most recognizable dinosaurs because they left a lasting impression, including on a Scottish island.Analysis of footprints show stegosaur roamed the Isle of Skye about 170 million years ago. it wasn't an isle then, it was a long-lost island in the Atlantic, and the site on the north-east coast was at the time a mudflat on the edge of a shallow lagoon. It contains a mixture of footprints, which means dinosaurs on Skye were more diverse than known.
In Ukraine and the west Russian Plain, there remain mysterious bone circles made from the remains of dozens of mammoths long ago. About 70 of them are known to exist. One, outside the modern village of Kostenki 250 miles south of Moscow, has been dated to 20,000 years in the past, making it the oldest such circular structure built by humans. A total of 51 lower jaws and 64 individual mammoth skulls were used to construct the walls of the 30 foot by 30 foot structure, now called Kostenki 11, and scattered across its interior. The bones were likely sourced from animal graveyards, and the circle was then hidden by sediment and is now a foot below current surface level.
