Researchers practice living on Mars - without leaving Earth

NASA Hubble Space Telescope picture of MarsFor 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.

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

A pregnant woman touches her stomach as people practice yoga on the morning of the summer solstice in New York's Times Square"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

The logo of Germany's largest drugmaker Bayer is pictured in LeverkusenFRANKFURT (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. ...

Keryx drug improves phosphorus, iron in kidney patients: trial

(Reuters) - A pivotal trial of Keryx Biopharmaceuticals Inc's experimental drug Zerenex showed that it improved levels of serum phosphorus and iron in patients on kidney dialysis, according to results published on Thursday. The trial involved 441 patients, according to the Journal of the American Society of Nephrology, which published the results. Over the four-week efficacy assessment period, mean serum phosphorus for Zerenex patients dropped by 2.2 milligrams per deciliter compared with placebo patients, the trial showed. Most patients with kidney disease that requires dialysis need chronic treatment with phosphate-binding agents to lower and maintain serum phosphorus at acceptable levels.

Is There a Happiness Gene?

Is There a Happiness Gene?Denmark and other Scandinavian countries regularly top world happiness rankings, and while many factors influence happiness, genetics may play a larger role than previously thought, according to the study authors. The new research examined the average genetic makeup of people in more than 100 countries, and compared how similar their genes were to people living in Denmark — a measurement called genetic distance. They found that the greater a nation's genetic distance from Denmark, the lower the reported well-being of that nation. The findings held even after the researchers took into account other factors that could affect happiness, such as GDP level and cultural differences, said Eugenio Proto, a professor of economics at the University of Warwick in the United Kingdom and one of the researchers on the study.

These Facial Features Matter Most to First Impressions

You may think you can judge a person you just met based on his or her facial expressions. First impressions of people — such as whether they are trustworthy, dominant or attractive — can develop from a glimpse as brief as 100 milliseconds or less. Because first impressions can affect people's future behavior and can be difficult to overturn, "it's useful to know how we're being judged on our appearance, especially since these judgments might not be accurate — think of effects on court cases or democratic elections, for example," said study co-author Tom Hartley, a cognitive neuroscientist and psychologist at the University of York in England. Although some previous research has suggested that there may be a kernel of truth in some first impressions, Hartley noted that people typically go too far with the judgments they develop from first impressions.

Earth May Be in Early Days of 6th Mass Extinction

Earth may be in the early stages of a sixth mass extinction, an international team of scientists says. Animals and plants are threatened. The world's remaining animals with backbones are 25 percent less abundant than in 1500— a trend also seen in invertebrate animals, such as crustaceans, worms and butterflies, the scientists reported. The previous mass extinction, which wiped out the dinosaurs, happened about 65 million years ago, likely from a catastrophic asteroid that collided with Earth.

Russia Restores Contact with Gecko-Filled Space Capsule

Russia Restores Contact with Gecko-Filled Space CapsuleA Russian space capsule carrying more than 20 science experiments — including a habitat full of geckos on a mission to mate in orbit — was feared to be in trouble for a few days after it stopped responding to commands from the ground. Oleg Ostapenko, head of the Russian space agency Roscosmos, told the Itar-Tass news agency on Saturday (July 26) that all systems were working normally and that commands were successfully sent to the Foton M4 capsule to continue its mission. With the help of a live feed from inside the geckos' habitat, scientists planned to monitor how microgravity affected the adult geckos' sexual behavior and embryonic development, Spaceflight Now reported last week. Roscosmos officials had announced that the spacecraft stopped responding on July 24.  Someone might want to pass along the good news to John Oliver.

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.

Happy Birthday, Landsat: Space Science Project Turns 42

Happy Birthday, Landsat: Space Science Project Turns 42The Landsat 1 satellite, a joint project of NASA and the U.S. Geological Survey, flew into orbit on July 23, 1972, from Vandenberg Air Force Base in California. The camera was designed to be the primary observation instrument, according to NASA, but scientists soon discovered that the scanner was sending back far better data. In 1976, scientists combing through Landsat images found a tiny scrap of land never seen before. To verify the island's existence, Canadian Hydrographic Service hydrologist Frank Hall took a helicopter to the island.

U.S. scientists to map interior of Mount St. Helens volcano

Aerial view of Mt St Helens as it spews steam and ash.By Victoria Cavaliere SEATTLE (Reuters) - A series of explosions set off by a team of scientists were expected to rattle Washington state's Mount St. Helens on Wednesday as researchers map the interior of the volcano, whose 1980 eruption was the deadliest in U.S. history. Mount St. Helens, about 95 miles (150 km) south of Seattle and 50 miles (80 km) north of Portland, erupted in an explosion of hot ash in May 1980, spewing debris over a wide area, killing 57 people and causing more than a billion dollars in damage. Scientists from across the United States are trying to get a better handle on the magma stores and internal workings of the 8,300-foot (2,530-meter) volcano to improve warning systems prior to eruption. "Mount St. Helens and other volcanoes in the Cascade Range threaten urban centers from Vancouver to Portland," lead scientist Alan Levander of Rice University in Houston said in a statement.

String Theory: The Physics of Master Guitar Playing

String Theory: The Physics of Master Guitar PlayingHow do great guitarists bend a string like Eric Clapton or Jimi Hendrix? "Very good guitarists will manipulate the strings to make the instrument sing," David Robert Grimes, a physicist at Oxford University, in England, who plays guitar and was a member of a band in Dublin, Ireland, said in a statement. The physics of string instruments is fairly well understood, but "I wanted to understand what it was about these guitar techniques that allows you to manipulate pitch," Grimes said. Grimes, who normally works on mathematical models of oxygen distribution in radiation therapy for cancer, spent his spare time crafting equations for various guitar techniques, including bending (pushing the strings up or down), tapping (hitting the strings), vibrato (moving the wrist back and forth to change a string's tension) and whammy bar action (a mechanical form of vibrato).

U.S. scientists urge 'national vision' to curb coastal risks in report

(Reuters) - A group of top scientists has called for a fundamental change to how the United States deals with risks to its Atlantic and Gulf coasts from storms and climate change in a National Research Council report released Wednesday. Urging a "national vision" toward addressing coastal risks, the report comes on the heels of a Reuters analysis published earlier this month showing that coastal flooding along the densely populated Eastern Seaboard of the United States has surged in recent years, with steep financial consequences. The great majority of money - most of it federal dollars -spent on coastal risks goes toward recovery after a disaster rather than on planning for and mitigating against storms, climate change and sea-level rise, the report said. Instead, the federal government should push for a national coastal risk assessment to identify best practices and uniform measures of progress, and move away from the current decentralized approach to coastal management, the report said.

Elephants Can Outsniff Rats and Dogs

Elephants Can Outsniff Rats and DogsElephants are known for their impressively long trunks, but perhaps less well known is the large number of genes that code for their sense smell. "Rats had the record for the largest number of [these] genes," said the study's lead researcher Yoshiihito Niimura, a researcher of molecular evolution at The University of Tokyo in Japan. The findings support other research on the pachyderm's superior sense of smell. African elephants can smell the difference between two tribes living in Kenya: the Maasai, whose young men prove their virility by spearing elephants, and the Kamba, farmers who usually leave elephants alone, reported a 2007 study published in the journal Current Biology.

Schizophrenia has many genetic links, study says

By Andrew M. Seaman NEW YORK - More than 100 locations on the human genome may play a role in a person’s risk of developing schizophrenia, according to a new study. While the results do not have an immediate effect on those living with the psychiatric disorder, one of the study’s authors said they open areas of research that had not seen advances in recent years. "The exciting thing about having little openings is it gives you a place to dig and make big openings,” said Steve McCarroll, director of genetics for the Stanley Center for Psychiatric Research at the Broad Institute in Cambridge, Massachusetts. McCarroll is part of the Schizophrenia Working Group of the Psychiatric Genomics Consortium, which published the study in the journal Nature.

New Schizophrenia Gene Links Uncovered

A new genetic analysis of people with schizophrenia — and the largest study investigating the genetic basis of any psychiatric disorder to date — provides hints that the disease may sometimes be connected with infections as some researchers have long suggested. There have been few innovative drug treatments for schizophrenia over the last 60 years. "In the past, people thought schizophrenia must happen because of some really bad mutations in a person not seen in people around them," said study co-author Steve McCarroll, director of genetics at the Stanley Center for Psychiatric Research at the Broad Institute of MIT and Harvard in Cambridge, Massachusetts. "This study shows a substantial part of the risk of schizophrenia comes from many tiny nudges to the genome that all humans share."

Full Moon Looms Large Over Your Sleep

Some folk stories and superstitions hold that a full moon affects people's sleep, and new research lends support to this idea. In the study, researchers found that people slept for 20 to 25 minutes less on average on nights with a full moon, compared with how long they slept on nights with a quarter moon. The people in the study also said they had more trouble falling asleep during the full moon than the quarter moon, according to the results, published July 8 in the journal Current Biology. The researchers stressed that further studies are needed to confirm whether there is a relationship between moon phases and sleep duration.

Genetic blueprint unveiled for vital food crop wheat

Wheat pours into a truck as a French farmer harvests his crop in Aigrefeuille-sur-Maine near NantesBy Will Dunham WASHINGTON (Reuters) - As far as agricultural genome research goes, this may be the best thing since sliced bread - wheat bread, that is. An international team of scientists on Thursday unveiled a genetic blueprint of wheat in an accomplishment that may help guide the breeding of varieties of the vitally important food crop that are more productive and more hardy. Researchers who are part of the International Wheat Genome Sequencing Consortium, formed in 2005 by a group of wheat growers, plant scientists and breeders, unveiled what they called a chromosome-based draft genome sequence of bread wheat, also known as common wheat. The work makes it easier to identify genes controlling agriculturally important traits like yield, disease and pest resistance and drought tolerance, according to Frédéric Choulet, a plant genomicist at the French National Institute for Agricultural Research (INRA), one of the lead researchers.

The mechanisms driving coronal rain are similar to the way rain forms on Earth, according to a statement released by the Royal Astronomical Society (RAS) in the United Kingdom. Scientists found that clouds of plasma in the corona cool, condense and fall back to the sun's surface in a waterfall-like arch if solar conditions are just right. "Showers of 'rain' and waterfalls on the sun are quite something, though I wouldn't recommend taking a stroll there anytime soon," Eamon Scullion of Trinity College Dublin in Ireland, who led the solar physics research, said in a statement.

Citizen scientists out of options to rescue old NASA satellite

By Irene Klotz CAPE CANAVERAL Fla. (Reuters) - A valiant effort to put a defunct NASA science satellite back to work came to a disappointing end this week after the 36-year-old spacecraft’s propulsion system failed, project organizers said. An ad hoc team of engineers and scientists won permission from NASA to try to take control of the International Sun-Earth Explorer-3, or ISEE-3. As ISEE-3 neared Earth’s orbit this spring, a volunteer team launched a crowd-funding campaign to raise money, eventually ending up with nearly $160,000. The group also petitioned NASA to let it try to redirect the probe into a stable orbit around Earth so it could resume science operations.

Why Some Chimps Are Smarter Than Others

Why Some Chimps Are Smarter Than OthersChimpanzees don't just get their smarts by aping others — chimps, like humans, inherit a significant amount of their intelligence from their parents, new research reveals. Researchers measured how well 99 captive chimpanzees performed on a series of cognitive tests, finding that genes determined as much as 50 percent of the animals' performance. "Genes matter," said William Hopkins, a neuroscientist at Georgia State University in Atlanta and co-author of the study published today (July 10) in the journal Current Biology. "We have what we would call a smart chimp, and chimps we'd call not so smart," Hopkins told Live Science, and "we were able to explain a lot of that variability by who was related to each other."

"We matched up the oil in the livers and flesh with Deepwater Horizon like a fingerprint," lead researcher Steven Murawski, a professor at the University of South Florida's College of Marine Science in Tampa, told Reuters. BP, whose oil rig caused the spill, rejected the research, stating in an emailed response that it was "not possible to accurately identify the source of oil based on chemical traces found in fish livers or tissue." BP's statement added, "vertebrates such as fish very quickly metabolize and eliminate oil compounds.

The Three Policies That Can Counter Global Warming (Op-Ed)

The Three Policies That Can Counter Global Warming (Op-Ed)For example, one such policy is to convert heavy-duty trucks to run on compressed natural gas (CNG) rather than diesel fuel. Ramón Alvarez and his colleagues at the Environmental Defense Fund, Princeton University, Rochester Institute of Technology and Duke University studied this option and found that it is "not a viable mitigation strategy for climate change," as it would be nearly 300 years after the fuel switch before net climate benefits are achieved. Policies that are effective at reducing emissions generally come in three types: economic signals, performance standards and policies to support innovation. Economic signals are policies that change the price of goods or activities in order to influence the choices made by people and businesses. Economic signals counter a key failure of markets: they do not properly value "externalities" (the positive and negative effects of an activity on society).  These effects are not limited to climate change.

The WMO's Commission for Climatology believes rising temperatures and more heatwaves and heavy rains mean the existing baseline, based on the climate averages of 1961-90, is out of date as a guide, the WMO said in a statement. "For water resources, agriculture and energy, the old averages no longer reflect the current realities," Omar Baddour, head of the data management applications at the WMO, told Reuters.

Pterygotids were a type of eurypterid, an extinct type of sea scorpion related to arachnids. Their closest living relatives are horseshoe crabs or modern sea scorpions, he said. Previously, these spooky sea monsters were thought to be fearsome predators, devouring armored fishes and giant cephalopods (related to modern squids and nautiluses).

"We wish to express the view that the HBP is not on course and that the European Commission must take a very careful look at both the science and the management of the HBP before it is renewed," the scientists wrote in the open letter. The Human Brain Project was launched in 2013 by the École polytechnique fédérale de Lausanne (EPFL) in Switzerland, and is funded primarily by the European Union. The project is Europe's equivalent of the United States' BRAIN Initiative, a proposed $4.5 billion, 12-year brain-mapping effort that President Obama launched in April 2013.

Fish Oil Supplements: Sound Science or Mostly Hype?

Among the many nutrition supplements trumpeted for potential health benefits, fish oil supplements have been among the most ballyhooed. Since then, long-term studies have revealed potential harms from taking fish oil unnecessarily. Fish oil supplements contain several vitamins and two significant omega-3 fatty acids, called eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids are found in a number of fish, so it is often recommended to get proper doses by eating oily fish twice a week.
