Pentagon appeals for scientists' help tracking anthrax shipments

By Sharon Begley NEW YORK (Reuters) - The Pentagon on Thursday asked microbiologists for help in tracking samples of anthrax that the army shipped to at least 51 labs in 17 U.S. states and three foreign countries, according to an announcement shared with Reuters. The request indicates that the Pentagon does not know where the anthrax wound up. Researchers who had worked with it at the Dugway Proving Ground biological lab in Utah thought the anthrax samples that they shipped had been killed, but at least one of the labs that received it said it in fact contained live spores.

Water Fights and Grown-Up Talk: How Dads Do It Differently

Dads toss their kiddos in the air, they roughhouse, and they're always game for a water-balloon fight. Thousands of studies have found differences, on average, in how dads and moms parent. From their willingness to tickle-fight to their grown-up speech, here are several ways dads parent differently from moms.

'Astronaut Wives Club' Post-'Launch' Review: Space History vs. Hollywood

"The Astronaut Wives Club," ABC's new drama about the women behind America's first spacemen, has left the launch pad. The premiere of the 10 episode "limited series," aptly titled "Launch," debuted Thursday (June 18), almost two years after the network announced it was adapting Lily Koppel's 2013 book about the "Astro Wives" for the small screen. Spanning two years over the course of the hour, the first episode followed the selection of NASA's original Mercury 7 astronauts in 1959 through the launch of Alan Shepard (played here by Desmond Harrington) to become the first U.S. astronaut to fly in space in May 1961.

Name a Mars Crater for Dad This Father's Day

If dad already has enough ties and coffee mugs, you could always name a Mars crater for him this Father's Day. The space-funding company Uwingu, which sells naming rights to the 580,000 cataloged Mars craters that have yet to receive a moniker, is offering a special deal: Name a crater between now and Father's Day (June 21) and receive a decorative certificate, either a downloadable digital version or a printed and framed one. In addition, the people who buy the 50 biggest craters through Father's Day get a gift certificate whose value equals that of their purchase, which they can use to name more Red Planet craters through the end of the year.

Father's Day Summer Solstice Marks Longest Day of the Year

Dads everywhere will celebrate Father's Day today (June 21), and the Earth is joining the fun this year with the summer solstice, kicking off the first day of the northern summer. The height of the midday sun has been getting progressively higher since Dec. 21 (the winter solstice), as its direct rays have been gradually migrating to the north. In the summer solstice, the sun stops its northward motion and begins heading south.

Solstice Science: How Humans Celebrate Official Start of Summer

Today (June 21) marks the summer solstice, the official start of summer in the Northern Hemisphere. The summer solstice is also the longest day of the year for places in the Northern Hemisphere, which means daylight will get progressively shorter each day until the winter solstice in December. For countries north of the Tropic of Cancer, the summer solstice takes place when the Earth's tilt toward the sun is at a maximum, and the sun is directly over countries located across the Tropic of Cancer, such as Mexico, Egypt, India, and southern China.

NYC Ivory Crush Sends Strong Anti-Poaching Message

NEW YORK — Some 1,500 people gathered in New York City's Times Square today (June 19) to witness the destruction of 1 ton of confiscated ivory — a move intended to demonstrate to the world that objects made from poached ivory have no value.

Will Pope Francis' Climate Encyclical Change the World?

Pope Francis has drawn the world's attention with a new encyclical that urges action on climate change. The papal letter, titled "Laudato si," or "On Care for Our Common Home," paints a bleak picture of Earth as sick and poisoned at almost every level. "The earth, our home, is beginning to look more and more like an immense pile of filth," Pope Francis wrote in the document, which is typically sent to bishops of all Roman Catholic churches.

Daddy's Here! Why Fathers Call Themselves 'Dad' Around Children

Parents are often their children's language coaches, said Lisa Pellerin, an associate professor of sociology at Ball State University in Indiana. "They're using the terms that they want the child" to use, Pellerin said. Parents may also avoid using pronouns such as "I" or "you" because they are "too abstract and it's somewhat confusing to kids," said Emie Tittnich, an infant mental health specialist at the University of Pittsburgh.

Earth's Mysteriously Light Core Contains Brimstone

Biblical views of the center of the Earth as a hellish pit raging with fire and brimstone have some support from new research. "In a way, we can also say that we have life imitating art," study lead author Paul Savage, a research scientist in the Department of Earth Sciences at Durham University in the United Kingdom, said in a statement."For millennia, tales have been told of the underworld being awash with fire and brimstone. The researchers estimate that the Earth's core contains 10 times the amount of sulfur than in the rest of the world, or comparable to about 10 percent of the mass of the moon.

Oklahoma's Surge in Earthquakes Due to Oil Production

Oklahoma is not known for its earthquakes, but in recent years episodes of ground shaking have surged, with the U.S. Geological Survey releasing a rare warning last May saying the risk of a damaging earthquake in Oklahoma had significantly increased. Now scientists say they know why seismic events have taken such a leap in the state: wastewater from oil and gas production that gets injected back into the ground. But even if companies stop injecting the water into the ground there, the researchers say the man-made earthquakes won't suddenly come to a halt due to a time delay they found between injection and seismic activity.

Happy New Year, Mars! NASA Toasts Martian Calendar Milestone

It's New Year's Day on the Red Planet today and NASA is celebrating in style with an epic three-day party in Mars itself … Mars, Pennsylvania, that is. NASA scientists and Mars experts have descended on the town of Mars to celebrate the Martian New Year today (June 18) with a press conference at 3 p.m. EDT (1900 GMT), which you can watch live on Space.com, courtesy of NASA TV. The press briefing, which NASA will convene at a flying saucer spaceship monument in Mars, Pennsylvania, kicks off a weekend of Mars-themed activities by NASA to inspire kids to pursue careers in science, technology, engineering, arts and mathematics – all fields that the space agency says it will need in its push to the Red Planet.

SyFy's 'Killjoys' Launches Bounty Hunters Across the Final Frontier

A trio of bounty hunters chase wanted criminals through space in the original science fiction series "Killyjoys," which debuts on the Syfy network tonight (June 19). In the fictional world of "Killjoys," people travel via spaceship through "the Quad," a central planet and its three moons populated by an array of human cultures (the pilot episode features some stunning images of the system). You can watch the first four minutes of the pilot episode here on Space.com.

Mix-n-Match Arms: Jellyfish Rearrange Limbs After Injury

Common moon jellies have an uncommon fix for injuries: When they lose limbs, they don't regrow them. This "symmetrization" is a never-before-seen method of self-repair, and one that probably helps jellies stay alive in the wild. Many invertebrates can regrow limbs, but scientists had never observed this sort of rearrangement before, said study researcher Michael Abrams, a graduate student in biology and biological engineering at the California Institute of Technology (Caltech).

8 Million Dog Mummies Found in 'God of Death' Mass Grave

In ancient Egypt, so many people worshiped Anubis, the jackal-headed god of death, that the catacombs next to his sacred temple once held nearly 8 million mummified puppies and grown dogs, a new study finds. The catacomb ceiling also contains the fossil of an ancient sea monster, a marine vertebrate that's more than 48 million years old, but it's unclear whether the Egyptians noticed the existence of the fossil when they built the tomb for the canine mummies, the researchers said. Ancient Egyptians built the temple and catacomb in honor of Anubis in Saqqara, a burial ground in the country's ancient capital of Memphis.

Gladiator Fights Revealed in Ancient Graffiti

Hundreds of graffiti messages engraved into stone in the ancient city of Aphrodisias, in modern-day Turkey, have been discovered and deciphered, revealing what life was like there over 1,500 years ago, researchers say. "Hundreds of graffiti, scratched or chiseled on stone, have been preserved in Aphrodisias — more than in most other cities of the Roman East(an area which includes Greece and part of the Middle East)," said Angelos Chaniotis, a professor at the Institute for Advanced Study, in Princeton New Jersey, in a lecture he gave recently at Toronto's Royal Ontario Museum. "Graffiti are the products of instantaneous situations, often creatures of the night, scratched by people amused, excited, agitated, perhaps drunk.

Giant 'Earth Stethoscope' Spies on Planet's Wonky Behavior

The international system, called the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), has been spying on Earth for the past 18 years, but researchers are still finding fresh ways to interpret its data. Here's a look at four things the CTBTO can see, hear and sniff on planet Earth. The CTBTO began as an anti-nuclear network that would help countries monitor and ban rogue explosions in the atmosphere, underwater or underground.

Real-Life 'Jurassic World' Dinos May Be 10 Years Off, Scientist Says

None of these sound quite as terrifying as the reptilian star in "Jurassic World," which set box-office records when it opened this past weekend. "Chickens and all birds are carrying much bigger chunks of dinosaur DNA than we are ever likely to find in the fossil record," said James Horner, the inspiration for the original Jurassic Park's Alan Grant. More recently, in his lab at Montana State University, Horner has been experimenting with bird DNA alteration for more than a decade.

Smart cycle jacket could save lives on Mexico City's roads

Mexico City's bumper-to-bumper traffic is a problem for the sprawling capital city's cyclists. Two inventors have developed a cyclist's vest complete with indicators, brake lights and an alert systems that can call for help. Damian Real, a physics students, came up with the design for the smart bike jacket with his partner Riberto Rivas, a maths major, at Mexico's National Autonomous University.

1 Ton of Illegal Ivory Will Be Publicly Destroyed in NYC Friday

In a public display against elephant poaching, U.S. officials will pulverize a huge store of illegal ivory tomorrow (June 19) in Times Square, in the heart of New York City. "The scale of the crisis has gotten to the point where 35,000 [African] elephants are killed every year — 96 a day," said John Calvelli, executive vice president of public affairs for the Wildlife Conservation Society (WCS). Calvelli, and other representatives from government and nongovernmental agencies, will speak at the event, which is scheduled to begin at 10:30 a.m. EDT in Duffy Square-Broadway Plaza in Times Square.

Did Sharks Really Kill That Cute Baby Dolphin?

A Philadelphia woman captured a shocking photo of a half-eaten baby dolphin while visiting the beach in Wildwood, New Jersey, last Saturday (June 13). The photo of the newborn animal's decimated carcass — allegedly rendered that way by sharks — was posted to Facebook and has since gone viral. Many people who saw the photo concluded that the Jersey shore is no longer a safe place for dolphins.

DNA sleuthing pinpoints two African elephant poaching hot spots

By Will Dunham WASHINGTON (Reuters) - DNA testing on tons of ivory seized from traffickers has identified two elephant poaching "hot spots" in Africa in a development scientists hope will spur a crackdown on the illegal trade decimating the population of Earth's largest land animal. Scientists said on Thursday genetic tests on 28 large ivory seizures, each more than half a ton, pinpointed the geographic origin of the tusks from the two types of African elephant, the savanna elephant and the somewhat smaller forest elephant. "We were very, very surprised to find that over the last decade almost all of these seizures came from just two places in Africa," said University of Washington biologist Samuel Wasser, whose study appears in the journal Science.

'The Next Trans Fat': Experts Predict Coming Food Battles

After years of research showing the harms of trans fat, the unhealthy substance has finally been banned as a food additive. On Tuesday (June 16), the Food and Drug Administration ruled that trans fat is not "generally recognized as safe" to be added to food, meaning that the ingredient will now be considered an illegal food additive. Companies have three years to either remove trans fat from their food, or petition the FDA for permission to use the additive in specific cases.

Here's More Proof Earth Is in Its 6th Mass Extinction

Diverse animals across the globe are slipping away and dying as Earth enters its sixth mass extinction, a new study finds. Over the last century, species of vertebrates are dying out up to 114 times faster than they would have without human activity, said the researchers, who used the most conservative estimates to assess extinction rates. Much of the extinction is due to human activities that lead to pollution, habitat loss, the introduction of invasive species and increased carbon emissions that drive climate change and ocean acidification, the researchers said.
