- Bionic ants could be tomorrow's factory workers By Amy Pollock Robotic ants the size of a human hand that work together could be the future of factory production systems. The developers, German technology firm Festo, say it's not just the unusual anatomy of real-world ants that inspired the bionic version - the collective intelligence of an ant colony was also something they wanted to replicate. Festo says that in the future production systems will be based on intelligent individual components that adjust themselves to different production demands by communicating with each other.
- Primordial sea creature with spiky claws unearthed in Canada
By Will Dunham WASHINGTON (Reuters) - A fossil site in the Canadian Rockies that provides a wondrous peek into life on Earth more than half a billion years ago has offered up the remains of an intriguing sea creature, a four-eyed arthropod predator that wielded a pair of spiky claws. Scientists said on Friday they unearthed nicely preserved fossils in British Columbia of the 508 million-year-old animal, named Yawunik kootenayi, that looked like a big shrimp with a bad attitude and was one of the largest predators of its time. The fossil beds in Kootenay National Park where it was found were in a previously unexplored area of the Burgess Shale rock formation that for more than a century has yielded exceptional remains from the Cambrian Period, when many of the major animal groups first appeared. Yawunik, whose name honors a mythical sea monster in the native Ktunaxa people's creation story, was a primitive arthropod, the highly successful group that includes shrimps, lobsters, crabs, insects, spiders, scorpions, centipedes and millipedes.
- Valeo's self-driving car systems learn from Safran drones
By Laurence Frost and Gilles Guillaume PARIS (Reuters) - French auto parts maker Valeo plans to draw on drone software and other military technologies from partner Safran to offer self-driving vehicle platforms to carmakers by the end of the decade. While demonstrating an autonomous car and other prototype systems jointly developed with Safran, the French defense and aerospace group, Valeo said on Friday the first applications may reach carmaker clients within three years. "We realized very quickly that we had much more in common than we'd expected," Valeo innovation chief Guillaume Devauchelle told Reuters. "It turns out that an autonomous vehicle is really a terrestrial drone." Cars that complete whole journeys without human input are still many years away, but creeping automation is well underway, with models already on sale that can pilot themselves through slow traffic and hit the brakes when a pedestrian steps out.
- U.S. Air Force overstepped bounds in SpaceX certification: report
By Andrea Shalal WASHINGTON (Reuters) - The U.S. Air Force overstepped its bounds as it worked to certify privately held SpaceX to launch military satellites, undermining the benefit of working with a commercial provider, an independent review showed on Thursday. The report cited a "stark disconnect" between the Air Force and SpaceX, or Space Exploration Technologies, about the purpose of the certification process and recommended changes. Air Force Secretary Deborah James ordered the review after the service missed a December deadline for certifying SpaceX to compete for some launches now carried out solely by United Launch Alliance, a joint venture of Lockheed Martin Corp and Boeing Co. The Pentagon is eager to certify SpaceX as a second launch provider, given mounting concerns in Congress about ULA's use of a Russian-built engine to power its Atlas 5 rocket.
- EU to resume Galileo satellite launch program By Francesco Guarascio BRUSSELS (Reuters) - The European Union is set to send two navigation satellites into orbit on Friday aboard a Russian rocket, in its first launch since a botched deployment in August that cost several million euros to fix. The Galileo project to set up an EU alternative to the U.S. Global Positioning System (GPS) is obliged to use the Russian Soyuz system until a development of Arianespace's European Ariane 5 rocket is ready around the end of the year, despite strained relations with Moscow over the conflict in Ukraine. An official at the European Commission, which oversees the program, said the EU executive was tendering for insurance cover for future satellites and had set up an insurance scheme for the launches. The two launched in August have since been nudged into viable orbits and are fit for use, a spokesman for the European Space Agency said.
- Tampons Can Screen for Leaking Sewage
Ordinary tampons can detect sewage pollution, a new study shows. "It's cheap, it's easy and it does the detective work," said study co-author David Lerner, a professor of environmental engineering at the University of Sheffield in the United Kingdom. But study author Dave Chandler, the Sheffield graduate student who came up with the tampon test, needed a cheap way to monitor stream pollution, Lerner said. Chandler realized that tampons could absorb optical brighteners, which are additives in laundry detergent, toothpaste and other cleaners that make colors and whites seem cleaner and brighter.
- Pesticides in Fruit Could Damage Sperm For men who are having fertility problems, eating lots of pesticide-laden fruits and vegetables may be bad news, a new study suggests. Among the men in the study, who were all attending a fertility clinic, those who ate lots of fruits and vegetables known to contain high levels of pesticides had about half as many sperm, and almost a third fewer normal sperm, than men who consumed less of the toxin-laden produce. "These results do not mean you should stop consuming fruits and vegetables," said Dr. Jorge Chavarro, the senior author of the new study and a professor of nutrition and epidemiology at Harvard University's School of Public Health. Rather, the study suggests that men seeking a healthy sperm count should eat fruit and vegetables that are organically grown, or known to be low in pesticide residues, Chavarro said.
- Egyptians Brewed Beer in Tel Aviv 5,000 Years Ago
Tel Aviv's reputation as a party city for expats might have started 5,000 years ago. During the Bronze Age, Egyptians were making beer in what is today downtown Tel Aviv, new archaeological evidence suggests. When archaeologists were conducting salvage excavations ahead of construction on new office buildings along Hamasger Street, they found 17 ancient pits that were used to store produce, according to an announcement from the Israel Antiquities Authority (IAA). "On the basis of previously conducted excavations in the region, we knew there is an Early Bronze Age site here, but this excavation is the first evidence we have of an Egyptian occupation in the center of Tel Aviv at that time," Diego Barkan, an archaeologist who was conducting the excavation on behalf of the IAA, said in the statement.
- NASA Astronaut Already Feels at Home in Space as 1-Year Journey Begins
NASA's Scott Kelly — one of two people spending a year on the International Space Station — already feels like the orbiting outpost is home. "It's great to be up here," veteran astronaut Kelly said during a live interview from the space station with NASA administrator Charles Bolden today (March 30). NASA officials hope that the research Kornienko and Kelly conduct on the station during their stay could help send astronauts to Mars by the 2030s. At the moment, NASA scientists know a lot about what happens to astronauts after six months in weightlessness — the usual amount of time a crewmember spends on the station.
- SpaceShipOne 'Lands' on Smithsonian Floor as Museum Renovates Hall
"It's hard to believe it's been here 10 years already," said Valerie Neal, chair of the museum's space history division and curator responsible for SpaceShipOne, in an interview with collectSPACE.com. SpaceShipOne's 'landing' was part of ongoing renovations to the hall, the first major redesign to Milestones since the museum opened in 1976. Workers carefully placed SpaceShipOne on the floor next to its formerly-suspended companion, Charles Lindbergh'socean-crossing airplane, the Spirit of St. Louis, which had been similarly lowered from Milestones' ceiling in January.
- Despite deforestation, the world is getting greener - scientists
By Alisa Tang BANGKOK (Thomson Reuters Foundation) - The world's vegetation has expanded, adding nearly 4 billion tonnes of carbon to plants above ground in the decade since 2003, thanks to tree-planting in China, forest regrowth in former Soviet states and more lush savannas due to higher rainfall. It is present in the atmosphere primarily as carbon dioxide (CO2) - the main climate-changing gas - and stored as carbon in trees. Through photosynthesis, trees convert carbon dioxide into the food they need to grow, locking the carbon in their wood. The 4-billion-tonne increase is minuscule compared to the 60 billion tonnes of carbon released into the atmosphere by fossil fuel burning and cement production over the same period, said Yi Liu, the study's lead author and a scientist at the University of New South Wales.
- Quantum Record! 3,000 Atoms Entangled in Bizarre State
Using a single particle of light, scientists have for the first time linked together thousands of atoms in a bizarre state known as quantum entanglement, where the behavior of the atoms would stay connected even if they were at opposite ends of the universe. The behavior of all the known particles can be explained using quantum physics. A key feature of quantum physics is that the world becomes a fuzzy, surreal place at its very smallest levels. One consequence of quantum physics is quantum entanglement, wherein multiple particles can essentially influence each other simultaneously regardless of distance.
- Environmental group seeks greater protection for USDA scientists An environmental activist group has filed a legal petition with the U.S. Department of Agriculture seeking new rules that would enhance job protection for government scientists whose research questions the safety of farm chemicals. The action filed on Thursday by the Public Employees for Environmental Responsibility, an advocacy group for local, state and federal researchers, came less than a week after a World Health Organization group found the active ingredient in Roundup, the world's best selling weed killer, is "probably carcinogenic to humans." Roundup is made by Monsanto Co. The petition to the USDA presses the agency to adopt policies to prevent "political suppression or alteration of studies and to lay out clear procedures for investigating allegations of scientific misconduct." According to the petition, some scientists working for the federal government are finding their research restricted or censored when it conflicts with agribusiness industry interests.
- Grants help level the playing field for young moms in science By Randi Belisomo (Reuters Health) - Thanks to a generous benefactor, young mothers doing laboratory research at the Massachusetts General Hospital in Boston can receive major grants to keep them from falling behind while they raise their children. Since 1993, the Claflin Distinguished Scholar Awards at MGH have helped junior female faculty with young children keep pace with their male peers, who don’t face the same challenges to research productivity that women do during their child-rearing years. Every year, five women are awarded $100,000 Claflin grants - named for benefactor Jane D. Claflin - to fund a research assistant for two years.
- Scientist defends WHO group report linking herbicide to cancer
A World Health Organization group's controversial finding that the world's most popular herbicide "probably is carcinogenic to humans" was based on a thorough scientific review and is a key marker in ongoing evaluations of the product, the scientist who led the study said Thursday. There was sufficient evidence in animals, limited evidence in humans and strong supporting evidence showing DNA mutations ... and damaged chromosomes," Aaron Blair, a scientist emeritus at the National Cancer Institute, said in an interview. Blair chaired the 17-member working group of the WHO's International Agency for Research on Cancer (IARC), which rocked the agricultural industry on March 20 by classifying glyphosate as "probably" cancer-causing. Monsanto Co , which has built a $15 billion company on sales of glyphosate-based Roundup herbicide and crops genetically engineered to tolerate being sprayed with Roundup, has demanded a retraction and explanation from WHO.
- More Infidelity Uncovered in King Richard III's Family Tree
The remains of Richard III may be locked away in a coffin to be reburied this week, but the 15th-century king's genome is still offering scientists a chance to unravel royal mysteries. "Having worked in the world of genetic genealogy for years, this is not at all surprising to me," said Turi King, a geneticist at the University of Leicester. In the general population, false paternities occur in about 1 percent to 2 percent of births, King said. They found a match between Richard's mitochondrial DNA (which is passed down only through the mother) and the mitochondrial DNA from two living female-line descendants of Richard's sister Anne of York: Michael Ibsen and Wendy Duldig.
- A Year in Space: The Science Behind the Epic Space Station Voyage
Science experiments conducted on the International Space Station during the orbiting outpost's first yearlong mission could help open the door to deep space for NASA. Officials hope that one-year stint on the space station by astronaut Scott Kelly and cosmonaut Mikhail Kornienko will provide them with valuable health data that may help when the space agency decides to send humans to Mars sometime in the future, a major goal for NASA. Scientists have collected a lot of data about how the human body behaves after six months in orbit on the space station, but what happens to a person after a year in space? When NASA's Kelly and Russia's Kornienko launch to space on March 27 for their yearlong stay in space, researchers will get one of their first chances to answer this question.
- Electric fault delays relaunch of CERN collider after two-year refit
By Robert Evans GENEVA (Reuters) - Scientists at Europe's CERN research centre have had to postpone the imminent relaunch of their refitted 'Big Bang' machine, the Large Hadron Collider, because of a short-circuit in the wiring of one of the vital magnets. "Current indications suggest a delay of between a few days and several weeks," a statement from the world's leading particle physics research centre said on Tuesday. Engineers had been expected to start on Wednesday pumping proton beams in opposite directions all the way round the two 27-km (17-mile) underground tubes in the LHC, closed down for the past two years for a refit. The smashing-together of particles inside the LHC is designed to mimic conditions just after the Big Bang at the dawn of the universe.
- Want an affordable earthquake warning system? Use animals, scientists say By Kieran Guilbert LONDON (Thomson Reuters Foundation) - Wild animals can predict earthquakes several weeks before they strike, and motion-activated cameras that track their movements could be adopted in quake-prone countries as an affordable early warning system, scientists said on Tuesday. Scientists using a series of cameras in an Amazon region of Peru noticed changes in animal behaviour three weeks before a 7.0 magnitude quake hit the area in 2011, according to a study published in the journal Physics and Chemistry of the Earth. Scientists have long believed that animals can predict earthquakes, but have until now relied on anecdotal evidence of changes in animal behaviour, they said. Rachel Grant, lead author of the report and lecturer in Animal and Environmental Biology at Britain's Anglia Ruskin University, said the study was the first to document a fall in animal activity before an earthquake.
- Obama, wowed by young scientists, announces new STEM pledges
WASHINGTON (AP) — The small Lego machine inside the White House whirred, and in a moment it was turning the pages of a story book. One page flipped, then another, ever faster as President Barack Obama marveled at its efficiency.
- Will We Combat Global Warming, Despite Our Nature? (Op-Ed) In a recent article (Human Nature May Seal the Planet's Warming Fate), I used the allegory of "Who Moved my Cheese?" to suggest that people's innate biases may in fact be an evolutionary adaption, one that thwarts the changes demanded by climate change. This in contrast to simpler life forms such as mice: They have seemingly lower cognitive abilities, yet adapt far easier and more willingly to changes in their habitat.
- Marijuana Science: Why Today's Pot Packs a Bigger Punch The marijuana that is available today may be much more potent than marijuana cultivated in the past, according to the results of new tests. The psychoactive component in the marijuana plant is the chemical THC, and the new tests showed that today's marijuana may contain 30 percent THC, Andy LaFrate, the author of the new report, said in a statement. By contrast, THC levels in marijuana 30 years ago were lower than 10 percent, said LaFrate, who is the president and research director at Charas Scientific, one of eight labs certified by the state of Colorado to conduct marijuana potency testing. At the same time, the marijuana samples tested had very low levels of a compound called cannabidiol, or CBD, that is touted for its medicinal properties.
- Kids Whose Ears Stick Out Are Cuter, Science Confirms The findings show that "protruding ears catch the eye, but not necessarily the imagination in a negative way," said Dr. Ralph Litschel, the lead author of the study. For some kids in the study, "protruding ears may have added to their cuteness," said Litschel, an ear, nose and throat specialist and facial plastic surgeon at Cantonal Hospital St. Gallen in Switzerland.
- From Rocket Science to Low Rider: Former Engineer Builds Adult Big Wheels
Now, a Big Wheel-style bike is available for adults, thanks to the work of a former aerospace engineer. As a kid, Matt Armbruster dreamed of being an astronaut. It may not seem quite as noble as building things that expand humanity's understanding of the universe, but Armbruster said the power of these trikes — which look like adult-size versions of the Marx Big Wheel for kids — is something to behold. "The original Marx Big Wheel was kind of like the best toy ever for entire generations," Armbruster said.
- Dude, why is my mushroom glowing? Scientists have the answer
By Will Dunham WASHINGTON (Reuters) - If you think you see a glowing mushroom, you might not be having a psychedelic hallucination. Some mushrooms indeed are bioluminescent, including one that sprouts among decaying leaves at the base of young palm trees in Brazilian coconut forests. Researchers said on Thursday that experiments in Brazil involving the big, yellow mushroom called "flor de coco," meaning coconut flower, showed its nighttime bioluminescence attracted insects and other creatures that could later spread its spores around the forest. "The answer appears to be that fungi make light so they are noticed by insects who can help the fungus colonize new habitats." Geneticist and molecular biologist Jay Dunlap of Dartmouth College's Geisel School of Medicine said bioluminescence had independently evolved many times in such diverse life forms as bacteria, fungi, insects and fish.
- Mystery of the 'Vampire Crabs' Solved
The crabs come from the island of Java in Indonesia, according to the scientists who officially describe the species in a new report. People in the aquarium trade have known of the two crab species described in the report for at least a decade, said Peter Ng, a biology professor at the National University of Singapore and an author of the report.
- Chris Borland Leaves NFL: The Science of Football and Brain Injury The up-and-coming professional football player Chris Borland, of the San Francisco 49ers, is now leaving the sport out of concern that a career in football would increase his risk of brain disease. On Monday (March 16), Borland announced he was retiring from football after studying the link between football head injuries and degenerative brain disease, and discussing his decision with friends, family members, concussion researchers and teammates, according to ESPN. The types of brain damage that can occur as a result of being a professional football player have received increased attention in recent years. For example, there is growing awareness of a particularly severe degenerative brain disease called chronic traumatic encephalopathy (CTE).
- Most Evangelical Christians Say Science and Religion Can Coexist
"Although many politicians and the media at large portray evangelicals as distrustful of science, we found that this is more myth than reality," Elaine Howard Ecklund, a sociologist at Rice University who orchestrated the survey, said in a statement. Among evangelical Christians, about 48 percent said they see science and religion as complementary to one another, while 21 percent think science and religion refer to different aspects of reality and see them as entirely independent of one another, the survey found. Still, the share of evangelical Christians who think religion and science are in conflict (and see themselves on the side of religion) is 29 percent — more than double the figure in the general population (14 percent), the study found.
- Aspirin's colon-cancer benefits backfire for some DNA types - study By Sharon Begley NEW YORK (Reuters) - Although numerous studies have shown that regular use of aspirin or related drugs can reduce the risk of colorectal cancer by about 30 percent, scientists have found an important exception: The medicines can actually increase the risk in people with certain genetic variants, new research shows. The result, published on Tuesday, is yet another step on the road to "precision medicine," which aims to match treatments to patients' genetic make-up. If confirmed, it could alter recommendations for preventing colorectal cancer, which is projected to kill 49,700 people in the United States this year. In an editorial accompanying a paper in the Journal of the American Medical Association, Dr. Richard Wender of the American Cancer Society and Thomas Jefferson University called the discovery "scientifically noteworthy." "I anticipate the time when genome sequencing to determine a lifelong (colorectal-cancer) prevention and screening strategy is a reality, although it's some time off," he said in an interview.
- Yeti Debate Swirls: Study Reveals Origin of Mysterious Hairs
The yeti, a legendary shaggy, bipedal beast from the Himalayas, made headlines last year when a geneticist said he had solved the mystery of its origins. "There is essentially no reason to believe that they [the hairs] belong to a species other than the brown bear," said one the new study's researchers, Eliécer Gutiérrez, a postdoctoral fellow of evolutionary biology at the Smithsonian's National Museum of Natural History in Washington, D.C.
- Seven strategies for keeping women in STEM fields Now an academic panel has developed a seven-point plan for achieving gender equity in so-called STEM fields: science, technology, engineering and math. The 28-member Initiative on Women in Science and Engineering Working Group hopes to “ensure that women not just enter science, but remain, compete, and truly excel in scientific careers.” Women account for half the college-educated American workforce but only 28 percent of science and engineering workers, according to the National Science Board. Susan Solomon, CEO of the New York Stem Cell Foundation, who convened the panel, says STEM fields are too critical to leave behind half the nation’s brainpower. Co-author Paola Arlotta, a Harvard University professor of stem cell and regenerative biology, won such an award at Massachusetts General Hospital, where the Claflin Distinguished Scholar Award helps sustain research productivity during child-rearing years.
- Horse dung has scientists on scent of antibiotic success Chemists around the world are involved in a race against time to find a solution to the growing problem of bacteria becoming resistant to antibiotics. It's a major threat to the health of the global population, which had long assumed that antibiotics would always be available to cure bacterial illness. The scientific community hopes to be able to develop a new range of antibiotics to replace those that are increasingly losing their ability to work against infections like Tuberculosis (TB). A research team led by Markus Aebi, Professor of Mycology at ETH Zurich (the Swiss Federal Institute of Technology in Zurich), believe they may have found the answer.
- Revved-up CERN collider aims to shed light on dark cosmos
By Robert Evans GENEVA (Reuters) - Scientists at the CERN physics research center said on Thursday the mystery dark matter that makes up 96 percent of the stuff of the universe will be a prime target for their souped-up Large Hadron Collider (LHC) in the coming years. I want to see the first light in the Dark Universe," CERN chief Rolf Heuer told a news conference, referring to a concept that includes not just dark matter but the dark energy believed to be driving the universe apart. "We don't know what dark matter is, but maybe there is a place where we can find it (in the LHC)," said Dave Charlton, spokesman for the ATLAS experiment at CERN, the European Organisation for Nuclear Research near Geneva. The press conference was called before the relaunch of the subterranean LHC later this month, after a two-year shutdown that saw its energy power doubled.
- Scientists call for halt on experiments changing DNA of human embryos By Sharon Begley NEW YORK (Reuters) - With rumors that scientists are about to announce they have modified the genes of human eggs, sperm, or embryos, five prominent researchers on Thursday called on biologists to halt such experiments due to fears about safety and eugenics. The call for a self-imposed research moratorium, which is extremely rare in science, was based on concerns that the work crosses an ethical line, said Edward Lanphier, president and chief executive officer of California-based Sangamo BioSciences Inc, senior author of the commentary published in the science journal Nature. "The research should stop." Rumors that one or more labs are on the verge of genetically-engineering a human embryo have swirled for months, he said. Critics of the work say the experiments could be used to try to alter the genetic quality of humans, a practice and belief known as eugenics.
- Mutating H7N9 bird flu may pose pandemic threat, scientists warn By Kate Kelland LONDON (Reuters) - A wave of H7N9 bird flu in China that has spread into people may have the potential to emerge as a pandemic strain in humans, scientists said on Wednesday. The H7N9 virus, one of several strains of bird flu known to be able to infect humans, has persisted, diversified and spread in chickens across China, the researchers said, fuelling a resurgence of infections in people and posing a wider threat. "The expansion of genetic diversity and geographical spread indicates that, unless effective control measures are in place, H7N9 could be expected to persist and spread beyond the region," they said in a study published in the journal Nature. The H7N9 bird flu virus emerged in humans in March 2013 and has since then infected at least 571 people in China, Taipei, Hong Kong, Malaysia and Canada, killing 212 of them, according to February data from the World Health Organization (WHO).
- Will Einstein's General Relativity Break Under Extreme Conditions?
In 1915, Albert Einstein published his general theory of relativity, which described gravity as a fundamental property of space-time. Now, scientists have the technology to begin looking for evidence that could reveal physics beyond general relativity. "To me, it is absolutely amazing how well general relativity has done after 100 years," said Clifford Will, a theoretical physicist at the University of Florida in Gainesville. General relativity describes gravity not as a force, as the physicist Isaac Newton thought of it, but rather as a curvature of space and time due to the mass of objects, Will said.
- Chance of major earthquake in California higher than thought - scientists
California has a 7 percent chance of experiencing an earthquake of magnitude 8 or larger over the next three decades, U.S. government scientists said on Tuesday, higher than thought before. The 7 percent probability is based on new modeling, the United States Geological Survey said in a new study. "We are fortunate that seismic activity in California has been relatively low over the past century," said Tom Jordan, Director of the Southern California Earthquake Center and a co-author of the study. "But we know that tectonic forces are continually tightening the springs of the San Andreas fault system, making big quakes inevitable." The new modeling system takes into account shaking that might occur on several different faults, rather than looking at each rupture as a separate incident, said Ned Field, the lead author of the USGS report.
- Ancient Chilean Mummies Now Turning into Black Ooze: Here's Why
The famous Chinchorro mummies, which have remained preserved in Chile for more than 7,000 years, are now under threat from increased levels of moisture. Humid air is allowing bacteria to grow, causing the mummies' skin "to go black and become gelatinous," said Ralph Mitchell, a professor emeritus of applied biology at Harvard University in Cambridge, Massachusetts, who examined the rotting mummies.
- Apple's ResearchKit to give scientists ready access to study subjects
By Julie Steenhuysen CHICAGO (Reuters) - Apple Inc on Monday released ResearchKit, an open-source software tool designed to give scientists a new way to gather information on patients by using their iPhones. Several top research institutions have already developed applications to work on the ResearchKit platform, including those pursuing clinical studies on asthma, breast cancer, heart disease, diabetes and Parkinson’s disease. They include Stanford University School of Medicine and Weill Cornell Medical College. "With hundreds of millions of iPhones in use around the world, we saw an opportunity for Apple to have an even greater impact by empowering people to participate in and contribute to medical research," said Jeff Williams, Apple’s senior vice president of Operations, said in a statement.
- Beyond Relativity: Albert Einstein's Lesser-Known Work
Einstein's breakthroughs in 20th-century physics made him the world's most famous scientist. In the 1870s, British chemist Sir William Crookes developed a neat little curiosity called the radiometer, or the light mill. The contraption was made up of a glass bulb with most of the air sucked out, with several metal, rectangular pieces aligned inside, like a windmill. He even convinced his niece Edith Einstein to focus on the topic for her research, said Daniel Kennefick, a physicist at the University of Arkansas and author of "Traveling at the Speed of Thought: Einstein and the Quest for Gravitational Waves" (Princeton University Press, 2007).
