Researchers practice living on Mars - without leaving Earth

For the most part, expedition leader Casey Stedman and his five crewmates have stayed inside their 1,000-square foot (93-square meter) solar-powered dome, venturing out only for simulated spacewalks and doing so only when fully attired in mock spacesuits. "I haven?t seen a tree, smelled the rain, heard a bird, or felt wind on my skin in four months,? Stedman wrote in a blog on Instagram. Stedman is a U.S. Air Force Reserve officer, graduate student at Embry-Riddle Aeronautical University Worldwide. ?We are simulating a long-duration mission on Mars, with a focus on crew psychology in isolation,? the crew said during an online interview with Reddit on Sunday.



Rocket blasts off with U.S. ?neighborhood watch? spy satellites

An unmanned Delta 4 rocket blasted off from Cape Canaveral Air Force Station in Florida on Monday with a pair of U.S. military satellites designed to keep watch on other countries? spacecraft. The 206-foot (63-meter) tall rocket, built by United Launch Alliance, a partnership of Lockheed Martin and Boeing, lifted off at 7:28 p.m. EDT and blazed through partly cloudy skies as it headed into orbit, a United Launch Alliance live webcast showed. Launch of two satellites for the U.S. Air Force?s recently declassified Geosynchronous Space Situational Awareness Program, or GSSAP, had been slated for July 23, but was delayed one day to resolve a technical issue with ground support equipment and then three more times by poor weather. Once in orbit, the GSSAP satellites, built by Orbital Sciences Corp, will drift above and below a 22,300-mile (35,970-km) high zone that houses most of the world's communications satellites and other spacecraft.



Evidence suggests babies in womb start learning earlier than thought: study

"It really pushed the envelope" in terms of how early babies begin to learn, lead researcher Charlene Krueger, associate professor at the University of Florida's College of Nursing, said on Thursday. Krueger had the women repeat three times out loud a set 15-second nursery rhyme, and do it twice a day for six weeks. The fetuses? heart rates were monitored at 32, 33 and 34 weeks as they listened to a recording of a female stranger recite the rhyme. By the 34th week, Krueger said, the heart rates of the tested fetuses showed an overall slight decline while listening to the recording, compared with a control group of fetuses whose heart rates slightly accelerated while listening to a recording of a new nursery rhyme.



Bayer says Nexavar fails in breast cancer study

FRANKFURT (Reuters) - German drugmaker Bayer said a Phase III trial of cancer drug Nexavar in patients with advanced breast cancer did not meet its primary endpoint of delaying the progression of the disease. The study, called Resilience, evaluated Nexavar in combination with chemotherapeutic agent capecitabine, in women with HER2-negative breast cancer. Oral drug Nexavar, which Bayer is developing jointly with Amgen, is approved for use against certain types of liver, kidney and thyroid cancer. Study details are expected to be presented at an upcoming scientific conference. ...



Scientists to excavate Wyoming cave with trove of Ice Age fossils
Scientists will begin excavation early next week of an ancient Wyoming sinkhole containing a rare bounty of fossil remains of prehistoric animals, such as mammoths and dire wolves, preserved in unusually good condition, researchers said on Thursday.    The two-week dig, set to begin next Monday under the direction of Des Moines University paleontologist Julie Meachen, marks the first exploration of Natural Trap Cave in north-central Wyoming since its initial discovery in the 1970s.
Stopping Deadly Ebola Outbreak Will Be a 'Marathon,' CDC Says
The deadly Ebola outbreak in West Africa is not showing any signs of slowing down, prompting U.S. health officials to issue more warnings for their staff in the region, encourage U.S. doctors to collect information about sick patients' travel histories and take more actions in the affected countries to bring the virus under control before it spreads to other regions.
Tumor Full of 232 'Toothlets': What's an Odontoma?
The boy was diagnosed with a condition called complex composite odontoma, a rare type of tumor that affects the jaw or gums, his doctors said. Ashik Gavai was admitted to JJ Hospital in Mumbai with swelling in his right jaw, Dr. Sunanda Dhiware, head of the hospital's dental department, told BBC News.   His father, Suresh Gavai, told the Mumbai Mirror that his son began complaining of severe pain a month ago. However, these pearl-like objects, aren't really teeth in the truest sense of the word, according to Dr. J. David Johnson an associate professor at the University of Tennessee Graduate School of Medicine and spokesperson for the American Dental Association.
Should You Trust Health Apps on Your Phone?
Personal health is becoming increasingly mobile, and there are now thousands of apps aiming to address everything from lifestyle issues to chronic diseases. Medical devices are generally regulated by the U.S. Food and Drug Administration, and although the FDA  reviews some apps, experts say the agency's power and efforts aren't nearly enough to cover the 97,000 and counting health apps out there that are transforming consumer health. "The FDA is woefully understaffed and under-resourced to oversee these things, particularly given the number of the thousands of apps that are [most likely] under FDA's jurisdiction," said health law expert Nathan Cortez, an associate professor of law at Southern Methodist University Dedman School of Law in Dallas, Texas. In an editorial published in The New England Journal of Medicine on Thursday (July 24), Cortez and his colleagues argued that health and medical apps hold the promise of improving health, reducing medical errors, avoiding costly interventions, and broadening access to care.
Huge European Cargo Ship Launches Its Last Delivery Flight to Space Station

A European space cargo ship as large as a double-decker bus blasted off for the International Space Station on Tuesday, marking the final space voyage for the huge robotic spacecraft.



Saturn's Moon Titan Sheds Light on Hazy Alien Planets

By peering into the haze of Saturn's huge moon Titan, scientists could learn more about how the atmospheres of alien worlds behave. The scientists used data collected from 2006 to 2011 by the Cassini spacecraft in the Saturn system to examine Titan's hazy atmosphere and learn more about how it works. Just as scientists try to understand the properties of stars by analyzing the light they emit, scientists study alien worlds by observing what happens to light as it passes through those planets' atmospheres. Scientists wait until the exoplanet passes, or transits, in front of its star, then gather the light with a telescope and use a prism to separate the light into its individual wavelengths, in the process gathering information about the planet's atmosphere, including its temperature, structure and overall composition.



No Fukushima radiation in tests off U.S. West Coast: scientists
By Courtney Sherwood PORTLAND Ore. (Reuters) - Tests of water off the U.S. West Coast have found no signs of radiation from Japan's 2011 Fukushima nuclear disaster, although low levels of radiation are ultimately expected to reach the U.S. shore, scientists said on Tuesday. Results obtained this week in tests of water gathered by an Oregon conservation group and tested by East Coast scientists came in as expected with no Fukushima-linked radiation, and five more tests are planned at six-month intervals to see if radiation levels will climb. "We've seen radiation halfway across the Pacific, north of Hawaii, but in U.S. waters there has been none, yet," Woods Hole Oceanographic Institution senior scientist Ken Buesseler said. Tests of some fish species, which can race across the ocean more quickly than slow-moving currents, have shown higher levels of radiation, although radiation levels in sea life off the U.S. shore are still safe, Buesseler said.
Quantum Wonderland: Neutron 'Cheshire Cats' Created

The Cheshire Cat of the classic children's book "Alice in Wonderland" had a smile that could disconnect from its body. For instance, a particle can apparently exist in two or more places at once or spin two opposite directions at the same time, a property known as superposition. Theoretical physicists last year predicted that the peculiar nature of quantum physics might allow the properties of particles to exist in two or more places simultaneously. This mimics the story of the Cheshire Cat, in which Alice notes, "Well! I've often seen a cat without a grin ? but a grin without a cat! It's the most curious thing I ever saw in all my life!"



Is Your Life Story Written in Your Poop?
In a new experiment, researchers studied gut and saliva bacteria in two people over a year, to investigate how microbial communities in people's bodies, called their microbiota, changed over time. The study participants provided stool and saliva samples nearly every day during the study period, and chronicled their daily health and behavior, including their diet, exercise, bowel movements and mood, using a diary app. The ratio then returned to normal when the study participant returned home, according to the study, led by Lawrence David, an assistant professor at Duke University Medical Center in Durham, North Carolina. In the other study participant, an intestinal infection with Salmonella, resulted in the permanent decline of most gut bacterial types, which were replaced by genetically-similar species, according to the study published today (July 24) in the journal Genome Biology.

People Use Just 8.2% of Their DNA, Study Finds
More than a decade has passed since the completion of the Human Genome Project, the international collaboration to map all of the "letters" in our DNA. The huge effort led to revolutionary genomic discoveries, but more than 10 years later, it's still unclear what percentage of the human genome is actually doing something important. The results are higher than previous estimates of 3 to 5 percent, and significantly lower than the 80 percent reported in 2012 by the Encyclopedia of DNA Elements Project (ENCODE), a public research project led by the U.S. National Human Genome Research Institute to study the role of the 3 billion total letters in human DNA. The differences may stem from the nuanced definition of "functional DNA," said the study's co-lead researcher Chris Ponting, a professor of genomics at the University of Oxford in England.
