Halloween Asteroid Flies By Earth Today: Watch It Live Online

A huge asteroid the size of the football stadium has a close encounter with Earth today (Oct. 31) and you can watch the space rock safely fly by online this Halloween. NASA scientists have dubbed asteroid a cosmic "Great Pumpkin" to celebrate the spooky holiday flyby. The asteroid poses no threat of hitting Earth, but it does give astronomers a tantalizing chance to ping the space rock with radar to learn more about what it's like.

Low-Fat Diets Are Not Better for Weight Loss

Low-fat diets are unlikely to result in greater weight loss than higher-fat diets that have the same amount of calories, a new study finds. The scientists found no difference in people's average weight loss when comparing low-fat and higher-fat diets. Reducing fat only led to greater weight loss when compared to not following any type of diet.

Women's Risk of Early Death Linked to Reproductive Milestones

Some factors related to a woman's reproductive health — such as the age at which she had her first period or the age at which she gave birth to her first child — may be related to her risk of dying early, a new study suggests. Still, "further studies are needed to confirm these findings and to identify the mechanisms that may link reproductive factors with risk of death," Merritt told Live Science.

People with Type 2 Diabetes Fall into 3 Distinct Groups, Study Finds

Type 2 diabetes doesn't affect every person who has it in exactly the same way, but now, a new study shows that people with Type 2 diabetes can be divided into a few distinct groups. The scientists found that there are actually three groups of people with Type 2 diabetes, each with a different set of problems associated with the disease. The findings show "there are statistically meaningful differences between patients," said Joel Dudley, the leader of the study and the director of biomedical informatics at the Icahn School of Medicine at Mount Sinai Hospital in New York.

The Spooky Effects of Sleep Deprivation

If a person is deprived of sleep, it can lead to "tremendous emotional problems," said Dr. Steven Feinsilver, the director of the Center for Sleep Medicine at Icahn School of Medicine at Mount Sinai in New York City. "Sleep deprivation has been used as a form of torture," he said. There isn't a clear definition of exactly how long a person must go without sleep, or how little sleep a person has to get to be considered sleep-deprived, and different people need different amounts of sleep, so there may be no universal definition of "sleep deprivation." Rather, a person is considered sleep-deprived if they get less sleep than they need to feel awake and alert, researchers say.

Allied Navies Destroy Mock Ballistic Missile in Practice Test

How many navies does it take to shoot down one ballistic missile? On Oct. 20, naval armed forces from nine different nations teamed up to shoot down a mock ballistic missile high above Earth's atmosphere. The fiery interception was part of a demonstration by the Maritime Theater Missile Defense (MTMD) Forum, an organization established in 1999 to promote cooperation among allied navies and to facilitate the coordination of sea-based defense systems.

'Be the Astronaut' and 'Journey to Space' in New Museum Exhibits

In Los Angeles, the California Science Center has debuted "Journey to Space," a hands-on, climb-aboard experience at what it takes to live and work off the Earth. And in Texas, Space Center Houston recently opened "Be the Astronaut," a multimedia exhibit that takes visitors on trips to the moon, Mars, asteroids, Jupiter and beyond. From exploring the International Space Station to landing on multiple worlds, these new, separate attractionsfeature authentic artifacts, replica space hardware and interactive displays to entertain and educate children and the general public about the physics, science and technology needed to support human space exploration, both now and in the future.

Halloween Fireballs Will Blaze in the Sky Through November

During the next couple of weeks, there is a fairly good chance that Earth will encounter a swarm of unusually large space particles, capable of generating some eye-catching fireball meteors. The Taurid meteors, sometimes called "Halloween fireballs,"(fireballs are extremely bright meteors) create one of this year's longest meteor showers, with at least a couple of shooting stars per hour from Oct. 20 to Nov. 30. Meteors — popularly known as "shooting stars" — are produced when debris enters and burns up in Earth's atmosphere.

Swim for the Earth: 3D-Printed Bikini Scrubs Water Pollution

Engineers from the University of California, Riverside, teamed up with designers from Eray Carbajo, an architecture and design firm based in New York City, to design a bikini that can absorb contaminants from water while a person swims. Sponge is a new material that engineers at UC Riverside started developing four years ago. "This is a supermaterial that is not harmful to the environment and [is] very cost-effective to produce," Mihri Ozkan, a member of the research team and an electrical engineering professor at UC Riverside's Bourns College of Engineering, told UCR Today, the school's online news publication.

Party Like It's 2500 B.C.: Stonehenge Builders Hosted Barbecues

The ancient builders of Stonehenge may have hosted massive barbecue cookouts where thousands of revelers feasted on meat, new research suggests. Archaeologists at the Neolithic settlement of Durrington Walls in modern-day southern England, where the builders of Stonehenge likely lived, found evidence that the village hosted open-air meat-roasting parties 4,500 years ago, with animals likely walking to the site for slaughter from regions far and wide. At the time, thousands of ancient pilgrims may have flocked to the site of Stonehenge to honor their dead, while heading back after hours to party and grill at Durrington Walls, the study authors speculated.

Tiny Bird Fossil Solves Big Mystery About Life After Dinosaurs

The newfound skeleton dates back to about 62.5 million to 62 million years ago, making it the oldest known modern bird specimen in North America to live after the dinosaur-killing mass extinction, the researchers said. "Birds were explosively diversifying right after the end of the Cretaceous, right after the big mass extinction," said study co-author Tom Williamson, curator of paleontology at the New Mexico Museum of Natural History and Science. "Maybe a dozen or less lineages of birds survived," said study co-author Daniel Ksepka, curator of science at the Bruce Museum in Greenwich, Connecticut.

Little Cousin: Human, Ape Ancestor Had 'Goggle Eyes'

The fossil of a small primate with "goggle" eyes that strode atop tree branches, snagging snacks of fruit, suggests the last common ancestor of all apes might have been less like humans' closest living relatives than often thought, researchers say. This discovery could shed light on what the last common ancestor of all apes and humans might have been like, scientists added. For instance, the newfound species was a small-bodied ape that would have weighed about 8.8 to 11 lbs. (4 to 5 kilograms), making it similar in size to the smallest living gibbons.

Halloween Asteroid Flyby: Here's What We Know About 2015 TB145

As a big asteroid flies by at a close but safe distance from Earth on Saturday (Oct. 31), astronomers will likely get a better radar view of the surface than ever before. Asteroid 2015 TB145 — discovered earlier this month, on Oct. 10 — will fly by slightly outside the moon's orbit. TB145 will fly by at 300,000 miles (480,000 kilometers) from Earth, but poses no threat to our planet.

Large asteroid set to shoot by Earth on Halloween

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - A large asteroid that scientists only discovered this month will make a relatively close approach to Earth on Saturday, astronomers say, providing one of the best opportunities in years to gather data about a passing space rock. The asteroid, estimated to be about 1,300 feet (400 meters) in diameter, will shoot past the planet at 22 miles (35 km) per second at around 1 p.m. (1700 GMT) on Halloween afternoon. Known as 2015 TB145, it will come within about 300,000 miles (480,000 km) of Earth, farther away than the moon but relatively close by cosmic measures.
