ananyo writes "Physicists have resurrected a particle that may have existed in the first hot moments after the Big Bang. Arcanely called Zc(3900), it is the first confirmed particle made of four quarks, the building blocks of much of the Universe's matter (abstract one, abstract two). Until now, observed particles made of quarks have contained only three quarks (such as protons and neutrons) or two quarks (such as the pions and kaons found in cosmic rays)."

This proposal indeed permits to extrapolate the hypothetical elements of the G-block and H-block in the same model."
illiteratehack writes "NASA has selected a 39-year-old chief technology officer to become a trainee astronaut. Josh Cassada is the current chief technology officer and co-founder of Quantum Opus, a firm that specialises in photonics. Cassada is one of eight individuals selected by NASA from 6,100 applicants for astronaut training, though what their future mission may be has yet to be revealed." Of the astronaut trainees selected, four of them are women — a new record.
theodp writes "Bill Gates already called dibbs on polio, so British Airways had to settle for tackling the 'global misalignment of talent' problem, putting '100 of the most forward-thinking founders, CEOs, venture capitalists, and Silicon Valley game-changers' on a flight from San Francisco to London to 'innovate and collaborate to find an effective solution to this growing global challenge.' UnGroundedThinking.com showcases the winning concepts, which include Advisher (an online community to help foster women in STEM), INIT ('nutritional labels' to disclose products' 'STEM ingredients'), DGTL (rewards young women with fashionable clothes for completing coding challenges), Beacons in a Backpack (solar powered backpacks pre-loaded with videos, multimedia content, and game-powered educational tools that also serve as mobile hotspots for rural/remote areas), Tech21 (STEM education program aimed at 21-years-and-older post-college grads in the workforce), Certify.me (allows STEM talent from across the globe to audition for potential employers via standardized-quality assessments), and STEAM Truck (a mobile dance lab where STEM art installations teach kids that science is fun and valuable). 'This has the feel of Southby [SXSW],' gushed a Google Ventures general partner. "It's a serendipitous occasion. It's about time we presented engineers to kids as role models — not just firefighters, cops, doctors, detectives. Who knows? Maybe The Internship changes that.'"
sciencehabit writes "Show a native-born Chinese person a picture of the Great Wall, and suddenly they'll have trouble speaking English, even if they usually speak it fluently. That's the conclusion of a new study, which finds that reminders of our home country can complicate our ability to speak a new language. The findings could help explain why cultural immersion is the most effective way to learn a foreign tongue and why immigrants who settle within an ethnic enclave acculturate more slowly than those who surround themselves with friends from their new country."
sciencehabit writes "In a few years, an iPhone app may give you a 3D layout of a room as soon as you step into it. Researchers have developed an algorithm that spits out the shape and contours of complex structures (including Switzerland's Lausanne Cathedral) using data compiled from four randomly placed microphones. The technology, which relies on the same sort of echolocation bats and dolphins use to navigate, could be used to develop more realistic echoes in video games and virtual reality simulations and to eliminate the echo from phone calls."
Lasrick writes "Evie Sobczak won a trip to Jet Propulsion Lab for her biofuel invention: 'For a fifth-grade science fair, Evie Sobczak found that the acid in fruit could power clocks; she connected a cut-up orange to a clock with wire and watched it tick. In seventh grade, she generated power by engineering paddles that could harness wind. And in eighth grade, she started a project that eventually would become her passion: She wanted to grow algae and turn it into biofuel.'"
kkleiner writes "A self-described think tank of engineers and inventors called Two Bit Circus have completed a successful crowdfunding campaign to launch a high tech reinvention of carnivals from yesteryear. The campaign raised over $100k to launch the STEAM Carnival (as in Science, Technology, Engineering, Art, and Math) to take place in Los Angeles and San Francisco next year. Showcasing robots, fire, and lasers, the goal of the carnival is to inspire young people into science and technology through these entertaining and educational events."
MTorrice writes "A surprising suite of microbial species colonizes plastic waste floating in the ocean, according to a new study. The bacteria appeared to burrow pits into the plastic. One possible explanation is that bacteria eat into the polymers, weakening the pieces enough to cause them to break down more quickly and eventually sink to the sea floor. While the microbes could speed the plastic's decay, they might also cause their own ecological problems, the researchers say."
Zothecula writes "Applied DNA Sciences (ADNAS) has developed a new approach to solve crimes using DNA tagging. The difference is that instead of tagging the objects being stolen, the company's system tags the perpetrator with DNA. While this has been tried before by applying the DNA to a fleeing criminal with a gun, ADNAS has adopted a more subtle approach."
First time accepted submitter Rebecka Schumann writes "Ontario couple Ken Campbell and Nicole Sauve said a recent fence installation led them to discover what is being labeled a historical find. Sauve, who said the duo originally believed the skeleton to be from bones of an animal, called the Ontario Provincial Police to investigate; Forensic Anthropologist Michael Spence confirmed the bones were that of an aboriginal woman who died at age 24 between the late 1500s to the early 1600s. In spite of reporting their find and Spence's evaluation, Suave and Campbell were told they were required to hire an archeologist to assess their property at their own expense under Ontario's Funeral, Burial and Cremation Services Act. The act, which requires evaluation for all properties found to house human remains, has the Canadian couple stuck with a big bill."

The discovery of Mahendraparvata, a 1,200-year-old lost city that predates Cambodia's famous Angkor Wat temple complex by 350 years, was part of the Hindu-Buddhist Khmer Empire that ruled much of Southeast Asia from about 800 to 1400 A.D., during a time that coincided with Europe's Middle Ages" The Age has a story of its own, with video.
New rules for labs that use chimpanzees as test subjects may be on the horizon. From the New York Times blog: "The Fish and Wildlife Service proposal came in response to a petition filed in 2010 by the Jane Goodall Institute, the Humane Society of the United States, the Association of Zoos and Aquariums and other groups. It would require permits for interstate commerce involving any chimpanzees, or for what the law calls 'taking,' which could be anything from harassment to major harm to something as simple as obtaining a blood sample. And those permits, Mr. Ashe said, would be granted only if the action could be shown to benefit the survival of the species. If the new rule is enacted, it will be a major success for animal welfare groups, a grave disappointment for some scientists and another sign of the profound changes over the last half-century in the way animals are used and imagined in science and popular culture." The L.A. Times lauds the proposed rule change in an editorial.
Thorfinn.au sends this quote from Space.com: "The pervading carpet of perchlorate chemicals found on Mars may boost the chances that microbial life exists on the Red Planet — but perchlorates are also perilous to the health of future crews destined to explore that way-off world. Perchlorates are reactive chemicals first detected in arctic Martian soil by NASA's Phoenix lander that plopped down on Mars over five years ago in May 2008. It is likely both of NASA's Viking Mars landers in 1976 measured signatures of perchlorates, in the form of chlorinated hydrocarbons. Other U.S. Mars robots — the Sojourner, Spirit and Opportunity — detected elemental chlorine. Moreover, orbital measurements taken by the Mars Odyssey spacecraft show that chlorine is globally distributed. [Phoenix principal investigator Peter Smith] said microbes on Earth use perchlorate for an energy source. They actually live off highly oxidized chlorine, and in reducing the chlorine down to chloride, they use the energy in that transaction to power themselves. In fact, when there's too much perchlorate in drinking water, microbes are used to clean it up, he said. Furthermore, seasonal flow features seen on Mars may be caused by high concentrations of the brines of perchlorate, which has a strong attraction to water and can drastically lower its freezing point, Smith told SPACE.com. The high levels of perchlorate found on Mars would be toxic to humans, Smith said."
schwit1 sends this news from Businesweek: "After 2,000 years, a long-lost secret behind the creation of one of the world's most durable man-made creations ever — Roman concrete — has finally been discovered by an international team of scientists, and it may have a significant impact on how we build cities of the future. Researchers have analyzed 11 harbors in the Mediterranean basin where, in many cases, 2,000-year-old (and sometimes older) headwaters constructed out of Roman concrete stand perfectly intact despite constant pounding by the sea. The most common blend of modern concrete, known as Portland cement, a formulation in use for nearly 200 years, can't come close to matching that track record. In seawater, it has a service life of less than 50 years. After that, it begins to erode. The secret to Roman concrete lies in its unique mineral formulation and production technique. As the researchers explain in a press release outlining their findings, 'The Romans made concrete by mixing lime and volcanic rock. For underwater structures, lime and volcanic ash were mixed to form mortar, and this mortar and volcanic tuff were packed into wooden forms. The seawater instantly triggered a hot chemical reaction. The lime was hydrated — incorporating water molecules into its structure — and reacted with the ash to cement the whole mixture together.'"
MarkWhittington writes "A draft version of the 2013 NASA Authorization Bill nixes any funding for President Obama's asteroid retrieval mission and instead directs NASA to return astronauts to the lunar surface as soon as possible, funding of course permitted. The NASA bill is currently working its way through the House Science Committee. Thus far the Senate has not taken up NASA authorization. However the cancellation of the asteroid retrieval mission and an insistence on returning to the moon, which both President Obama and NASA Administrator Charles Bolden have opposed, would place Congress on a collision course with the White House should that version of the bill be passed by both houses of Congress."
alphadogg writes "Medical device makers should take new steps to protect their products from malware and cyberattacks or face the possibility that U.S. Food and Drug Administration won't approve their devices for use, the FDA said. The FDA issued new cybersecurity recommendations for medical devices on Thursday, following reports that some devices have been compromised. Recent vulnerabilities involving Philips fetal monitors and in Oracle software used in body fluid analysis machines are among the incidents that prompted the FDA to issue the recommendations."
aarondubrow writes "Researchers recently created OpenfMRI, a web-based, supercomputer-powered tool that makes it easier for researchers to process, share, compare and rapidly analyze fMRI brain scans from many different studies. Applying supercomputing to the fMRI analysis allows researchers to conduct larger studies, test more hypotheses, and accommodate the growing spatial and time resolution of brain scans. The ultimate goal is to collect enough brain data to develop a bottom-up understanding of brain function."
An anonymous reader writes "Today Mozilla announced the Mozilla Science Lab, a project to help modernize scientific practices to make better use of the open web. "Scientists created the web — but the open web still hasn't transformed scientific practice to the same extent we've seen in other areas like media, education and business. For all of the incredible discoveries of the last century, science is still largely rooted in the "analog" age. Credit systems in science are still largely based around "papers," for example, and as a result researchers are often discouraged from sharing, learning, reusing, and adopting the type of open and collaborative learning that the web makes possible.' Hopefully this can be another step in moving away from traditional publishing practices, and encourage a new generation of scientists to make their data available in more useful ways."
taikedz writes "Fiona Fox, chief executive of the Science Media Center, has claimed that leading scientists independently advising the UK government are being actively prevented from speaking to the public and media, especially in times of crisis when scientific evidence is necessary for a fully open and educated public debate, such as the current badger culling policy, and the past volcanic eruptions and ash fallout and their effects. The Department for Environment, Food and Rural Affairs, whom many of these scientists are advising, denies any such practices."
