Snake in the Grass! Huge Everglades Python Shows Invasive Issue

A giant python — about as long as a shipping container — that was captured in Everglades National Park in Florida earlier this month has now been euthanized, authorities say. The accidental finding of this snake shows how easily even huge pythons can remain hidden in Florida's swampy south, experts say. The creature weighed a whopping 133 lbs. (60 kilograms), and at 18-feet, 3-inches (5.6 meters), was almost as long as the largest python ever captured in the state of Florida, which was 18-feet, 8-inches long (5.7 meters).

New Ebola Vaccine: Will It Help to End Outbreaks?

Experts welcomed the news today that a recent trial of an Ebola vaccine suggests the shot is highly effective at preventing the disease, and said that the the vaccine may stem outbreaks in the future even if not everyone is vaccinated. The study shows that the new vaccine, known as VSV-ZEBOV, "may help finally extinguish this [Ebola] outbreak," said Dr. Amesh Adalja, an infectious-disease specialist and a senior associate at the University of Pittsburgh Medical Center's Center for Health Security. In the study, researchers in Guinea vaccinated people who had contact with people who were infected with Ebola, as well as the contacts of those contacts — a technique known as "ring vaccination" (referring to vaccinating the ring of people surrounding a case).

Viral Soda Infographic: How Does Cola Really Affect the Body?

An infographic that breaks down what happens in your body after you drink one Coke has gone viral, but health experts say some information in the graphic is exaggerated. In addition, while soda is certainly not a healthy food choice, drinking a sugar-sweetened beverage once in a while wouldn't necessarily make a person unhealthy, the experts said. "If you're drinking one soda on occasion … that doesn't equate to it being necessarily unhealthy," said Heather Mangieri, a spokesperson for the Academy of Nutrition and Dietetics and owner of the nutrition consulting company Nutrition Checkup in Pittsburgh.

Epic Yearlong Space Mission Documented in Time Magazine Web Series

On July 8, Time magazine posted the first two episodes in a 10-part documentary Web series following NASA astronaut Scott Kelly's unprecedented yearlong space mission. The documentary, which will be released in stages throughout the 12 months Kelly and cosmonaut Mikhail Kornienko are spending aboard the International Space Station, offers an inside look not only into the mission, but also into Kelly's life as an astronaut. "We will continue with at least nine hours of interviews with Scott, his family, the girlfriend he's leaving behind and the doctors who will be looking after him while he's in orbit," Time representatives said in a statement about the documentary.

U.S. Air Force closely following SpaceX blast probe: general

The U.S. Air Force is involved in and closely following a SpaceX-led investigation into the explosion that destroyed an unmanned Falcon 9 rocket minutes after liftoff from Florida on June 28, a top general said on Friday. Lieutentant General Samuel Greaves, who heads the Air Force Space and Missiles Systems Center, did not address those concerns directly.

New Dinosaur's Powerful Sniffer Helped It Track Prey

While pursing his Ph.D. at the University of Pennsylvania, Steven Jasinski fulfilled a childhood dream: he discovered a brand new dinosaur. Jasinski, a doctoral candidate in the Department of Earth and Environmental Science and curator of paleontology and geology at the State Museum of Pennsylvania, was reviewing the museum's collection when he found a fossil that caught his eye. "As soon as I looked at the specimen, I could tell it was not the dinosaur it was thought to have been," he told Live Science.

Lexus' New Hoverboard Is Cool, But Will It Fly?

Last month, Japanese auto manufacturer Lexus unveiled its newest product, and it's not another luxury SUV. The video shows the sleek board floating over what appears to be regular cement in a skateboard park, leading some hoverboard enthusiasts to speculate that, at long last, someone has produced a flying skateboard that you can actually ride in a halfpipe or down a sidewalk. But, if you thought Lexus' new toy would turn you into Marty McFly from "Back to the Future Part II" (the one with the epic hoverboard chase scene), think again.

America Offline? 15 Percent of US Adults Don't Use the Internet

Email, Facebook, cat videos — these are just a few of the things that 15 percent of American adults are missing out on every day because they don't use the Internet. However, that 15 percent is a huge reduction from the percentage of Americans who did not use the Internet in 2000, according to a new analysis of survey data by the Pew Research Center, a nonprofit organization in Washington, D.C. In that year, almost half of all Americans (48 percent) said they didn't go online. Since then, despite efforts by the government and social service organizations to encourage Americans to get online, that number hasn't budged, according to Pew.

Blue Moon of 2015 Thrills Skywatchers with Lunar Beauty (Photos)

The second full moon of July wowed skywatchers around the world - and even in space - on Friday, offering the lunar treat of a so-called Blue Moon that won't be seen again until 2018. NASA and Space.com readers across the United States and abroad captured amazing photos of the Blue Moon on Friday (July 31), but perhaps the most remote view came from space. When in space 4 a [year] everything is possible," NASA astronaut Scott Kelly wrote on Twitter while posting a photo of the full moon.

Earth's 'magnetic personality' much older than previously thought

By Will Dunham WASHINGTON (Reuters) - Earth's magnetic field has been a life preserver, protecting against relentless solar winds, streams of charged particles rushing from the Sun, that otherwise could strip away the planet's atmosphere and water. "It would be a pretty barren planet without it," said University of Rochester geophysicist John Tarduno. Researchers on Thursday said evidence entombed in tiny crystals retrieved from the outback of western Australia indicates the magnetic field arose at least 4.2 billion years ago, much earlier than previously believed.

When is a jackal not a jackal? When it's really a 'golden wolf'

Scientists said on Thursday a comprehensive genetic analysis found that these populations are made up of two entirely distinct species, with those in Africa different from the others. The scientific name for the golden jackal is Canis aureus. The researchers proposed renaming those in Africa Canis anthus, or the African golden wolf.

U.S. lawmakers question NASA, Air Force on blast probe led by SpaceX

By Andrea Shalal WASHINGTON (Reuters) - Fourteen U.S. lawmakers on Thursday told the Air Force and NASA they had "serious concerns" about the fact that SpaceX is leading an investigation into the June 28 explosion of its Falcon 9 rocket, and whether it would receive enough oversight. Republican Representatives Mike Coffman from Colorado and Randy Forbes from Virginia led the bipartisan group, which questioned the two government agencies about what the explosion means for future NASA and Air Force launches.

Zoom In on NYC in United Nations' 'My Planet from Space' (Video)

This gorgeous satellite view of the busy Big Apple as seen from orbit offers a glimpse into the new "My Planet from Space" exhibit currently on view at the United Nations. The video shows a satellite photo of New York City, pointing out the metropolis' boroughs before focusing in on the United Nations building, the home of the new exhibition. The image was captured by Japan's ALOS satellite in June 2010, with the European Space Agency unveiling it as part of its Earth from Space video series to spotlight the U.N.'s "My Planet from Space: Fragility and Beauty" exhibit.

Closest Rocky Alien Planet Discovered

Astronomers have discovered a rocky exoplanet that lies just 21 light-years from Earth — closer than any other confirmed rocky alien world. The alien planet, called HD 219134b, is about 4.5 times more massive than Earth, making it a so-called "super Earth," a new study reports. HD 219134b lies extremely close to its host star, completing one orbit every three days, so its surface is too hot to harbor life as we know it, researchers said.

Blue Moon Full Moon Rises Tonight: What to Expect

There's a "Blue Moon" in the sky tonight — but that doesn't mean the lunar surface will turn indigo. Tonight's (July 31) moon will be a gorgeous sight, but it won't look different than any other full moon. The term Blue Moon has come to refer to the second full moon in a given month (since full moons come around about every 29 days, most months only contain one).

For Dr. Seuss, Nonsensical Rhymes Came with a Reason

Most fans of Dr. Seuss can predict how a line from one of his books will end the moment they hear the beginning. For instance, many will fondly remember the line, "I do not like green eggs and ham," and be able to parrot what comes next: "I do not like them Sam I Am." The predictability of Dr. Seuss' lines and imaginative drawings have been catnip to young readers for decades. Now, more than half a century after "Green Eggs and Ham" (Random House, 1960) was published, Dr. Seuss is asking a new generation of readers, "What Pet Should I Get?" (Random House, 2015).

NYC Light Show Aims to Raise Awareness About Endangered Species

On Saturday (Aug. 1), New York's Empire State Building will be converted into a giant billboard to draw attention to the plight of endangered animals around the world. From 9 p.m. to midnight EDT on Saturday, the Empire State Building's southern face will feature images of a snow leopard, a golden lion tamarin, a manta ray and many other creatures that could soon be wiped out in Earth's sixth mass extinction, according to Louie Psihoyos and Travis Threlkel, the organizers of the upcoming event. Psihoyos, a photographer and Academy Award-winning filmmaker (he directed the 2009 Oscar-winning documentary "The Cove"), is co-founder of the animal rights and conservation organization Oceanic Preservation Society (OPS).

Shake, Rattle and Build: Colliding Bricks Self-Assemble Into Objects

A team of researchers at Israel's Bar-Ilan University built a cylinder from half-inch (about 1.3 centimeters), pyramid-shaped "bricks" of plastic, each with a set of small depressions and studs on its sides and a magnet under the surface. In their experiment, Hacohen and her team put the bricks in a container and spun them at rotation frequencies between 200 and 350 revolutions per minute.

'Magnetic' Discovery May Reveal Why Earth Supports Life and Mars Doesn't

Earth's magnetic field, which protects the planet from harmful blasts of solar radiation, is much older than scientists had previously thought, researchers say. Without Earth's magnetic field, solar winds — streams of electrically charged particles that flow from the sun — would strip away the planet's atmosphere and oceans. As such, Earth's magnetic field helped to make life on the planet possible, researchers have said.

Deadly Fungus Could Threaten US Salamanders

Each year, thousands of live salamanders arrive in shipments on U.S. shores, a trade that must stop immediately, scientists say. According to new research, a ban on salamander imports is crucial to stopping the spread of a deadly fungus that kills almost every salamander it infects. Batrachochytrium salamandrivorans, also known as Bsal, is a chytrid fungus, and a close relative of Batrachochytrium dendrobatidis (Bd), a frog fungus that is threatening species worldwide.

1 in 5 Adult Americans Report Having a Disability

About one in eight adults say they have mobility limitations, such as difficulty walking or climbing stairs, making this the most common type of disability, according to the report. The South had the highest percentages of people with disabilities, according to the report. Although the report did not analyze the reasons for the disparity between states, the South tends to have higher rates of chronic diseases associated with disability, including heart disease and diabetes, than the rest of the country, the CDC said.

Exercise in Teen Years Tied to Lower Mortality Later

During the study, 5,282 of the women died, including 2,375 who died from cancer and 1,620 who died from cardiovascular disease. "In women, adolescent exercise participation, regardless of adult exercise, was associated with reduced risk of cancer and all-cause mortality," study author Sarah J. Nechuta, an assistant professor of medicine Vanderbilt-Ingram Cancer Center in Nashville, Tennessee, said in a statement.

'Leaky' Vaccines May Fuel Evolution of Deadlier Viruses

Some vaccines may cause viruses to evolve into deadlier forms, a new study suggests. The effect has so far been demonstrated with just one bird virus, though it's possible it may also occur with some human vaccines, the researchers said.

Cheers! 'Blue Moon' Beer Celebrates Lunar Sight for 20th Anniversary

In a coincidence of cosmic proportions, the second full moon of July rises tonight, making it a so-called "Blue Moon" — and Blue Moon Brewing Co. will celebrate its 20th anniversary by painting the town red. A celestial Blue Moon comes around roughly every 2.7 years. Tonight (July 31), a Blue Moon will rise on the same night as Blue Moon Brewing Co. celebrates its 20th anniversary with parties and events at more than 750 locations across the country.
