Archaeologists Discover Lost City In Cambodian Jungle 91

First time accepted submitter steve_mark66 writes "Australian archaeologists using remote-sensing technology have uncovered an ancient city in Cambodia that has remained hidden for more than a millennium under dense jungle undergrowth. 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.

Proposed Rule Would Drastically Restrict Chimp Research 134

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.

Future Astronauts Must Deal With Toxic Chemicals In Martian Soil 117

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."

Ancient Roman Concrete Is About To Revolutionize Modern Architecture 322

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.'"

Draft NASA Funding Bill Cancels Asteroid Mission For Return To the Moon 237

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."

FDA Calls On Medical Devicemakers To Focus On Cybersecurity 40

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."

A Database of Brains 25

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."

Mozilla Launches Initiative To Adapt Scientific Practice To the Open Web 28

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."

UK Government 'Muzzling' Scientists 83

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."

Do-It-Yourself Brain Stimulation Has Scientists Worried 311

Freshly Exhumed writes "Dave Siever always fancied himself as something of a musician, but also realized he did not necessarily sing or play in perfect key. Then he strapped on the electrodes of a device made by his Edmonton company, and zapped his brain's auditory cortex with a mild dose of electricity. The result, he claims, was a dramatic improvement in his ability to hear pitch, including the sour notes he produced himself. 'Now I tune everything and I practise my singing over and over and over again, because I'm more sensitive to it.' Mr. Siever was not under the supervision of a doctor or psychologist, and nor is he one himself. He is part of an extraordinary trend that has amateur enthusiasts excited, and some scientists deeply nervous: do-it-yourself brain stimulation." With studies suggesting that small doses of electricity can: increase your memory, help you learn new tasks, make you better at math, turn you into a sniper in minutes, and most importantly make the ugly seem attractive, we can expect a lot of brain zapping in the next few years.

World Population Could Reach Nearly 11 Billion By 2100 322

vinces99 writes "A new analysis shows that world population could reach nearly 11 billion by the end of this century, according to a United Nations report issued June 13. That's about 800 million, or about 8 percent, more than the previous projection issued in 2011. The change is largely because birth rates in Africa have not declined as quickly as had been expected, according to Adrian Raftery of the University of Washington's Center for Statistics and the Social Sciences. The U.N. estimates use statistical methods developed at the center. The current African population is about 1.1 billion and it is now expected to reach 4.2 billion, nearly a fourfold increase, by 2100, Raftery said."

Supreme Court: No Patents For Natural DNA Sequences 214

ColdWetDog writes "The ongoing story of Myriad Genetics versus the rest of the world has come to an end. In a 9-0 decision, the US Supreme Court has decided that human genes cannot be patented. From a brief Bloomberg article: 'Writing for the court, Justice Clarence Thomas said isolated DNA is a "product of nature and not patent eligible merely because it has been isolated." At the same time, Thomas said synthetic molecules known as complementary DNA, or cDNA, can be patented because they require a significant amount of human manipulation to create.' Seems perfectly sane. Raw genes, the ones you find in nature are, wait for it — natural. Other bits of manipulated DNA / RNA / protein which take skill and time to create are potentially patentable. Oddly, Myriad Genetics stock actually rose on that information." Adds reader the eric conspiracy: "The result for Myriad is that they still have protection for their test, however the decision also allows researchers to work with the DNA sequences that are predecessors to the cDNA used in the test." Here's an AP report on the ruling, as carried by the Washington Post.

Researchers Discover Another Layer To the Cornea 74

puddingebola writes with this excerpt: "A previously undetected layer in the cornea, the clear window at the front of the human eye, has been discovered by scientists at The University of Nottingham. This new layer, called the Dua's Layer after Professor Harminder Dua who discovered it, could help surgeons to dramatically improve outcomes for patients undergoing corneal grafts and transplants. This is a major discovery that will mean that ophthalmology textbooks will literally need to be re-written. Having identified this new and distinct layer deep in the tissue of the cornea, we can now exploit its presence to make operations much safer and simpler for patients," said Dua, Professor of Ophthalmology and Visual Sciences."

Crowd-Funded Radio Beacon Will Message Aliens 196

astroengine writes "In the hope of uniting people around the globe in a long-duration project to send a radio 'message in a bottle' METI (Messaging Extraterrestrial Intelligence) signal, a crowd-funded project utilizing a refurbished radio telescope in California has begun its work. Lone Signal is a project initiated by scientists, businessmen and entrepreneurs to set up a continuous radio beacon from Earth. To support the operations of the Jamesburg Earth Station radio dish in Carmel Valley, Calif. (a dish built to support the Apollo 11 moon landing in 1969), a crowd-funding effort has been set up so that for a small fee, users can send images to the stars. If you're content with sending a text message, your first message is free. The radio dish's first target is Gliese 526, a red dwarf star 18 light-years from Earth, but the project will be considering other stellar targets believed to be harboring habitable worlds."

Fly, Drones, and Bring Me Data 18

New submitter ScienceMon writes "Emma Maris reports in Nature how unmanned aerial vehicles, or drones, are starting to catch on among scientific researchers who are using them to keep tabs on volcanoes, track endangered species, hunt down weeds, and a range of other uses. At the same time, engineers are designing ever-more sophisticated drones that can navigate and collect data autonomously. '[R]esearchers from UC Boulder have used UAVs to measure jets of wind that scream down from the Antarctic plateau into Terra Nova Bay. Such measurements could help scientists to understand the dynamics of sea-ice formation around Antarctica, which creates dense salty water that sinks and helps to drive global ocean currents. "Nobody had an aircraft out there during winter when the winds are strongest and took measurements because the conditions are too extreme," says Maslanik. The data collected so far, he says, show unexpectedly complex wind patterns, including fierce, localized jets that push sea ice off shore and speed up its formation.'"

Computer Memory Can Be Read With a Flash of Light 69

ananyo writes "A new kind of computer memory can be read 10,000 times faster than flash memory using pulses of light, taking advantage of principles used in solar panel design. Researchers built the prototype device using bismuth ferrite. In conventional computer memory, information is stored in cells that hold different amounts of electric charge, each representing a binary '1' or '0.' Bismuth ferrite, by contrast, and can represent those binary digits, or bits, as one of two polarization states, and, because of its photovoltaic properties, can switch between these states in response to visible light."

International Linear Collider Design Ready To Go 71

Via El Reg comes news that the International Linear Collider's Technical Design Report is finished, leaving only funding in the way of construction. From the article: "A five volume report containing the plans for the International Linear Collider has been handed over to the International Committee for Future Accelerators (ICFA) for approval. The Technical Design Report contains costings for the project, along with the design of the new collider. The new machine is significantly more powerful than the hoary European Large Hadron Collider and is likely to be sited in Japan, because the Pacific island nation has reportedly offered to pay for half of the construction costs. ... Jonathan Bagger, chair of the International Linear Collider Steering Committee, said the particle collider was 'ready to go.' 'The publication of the Technical Design Report represents a major accomplishment,' he continued. ... The ILC consists of two linear accelerators facing each other. " A few years late, but hopefully not never.
