from the watch-the-show dept.
An anonymous reader writes Tonight, Asteroid 2004 BL86 will make a pass by the Earth at just 745,000 miles away. This should offer stargazers a great opportunity to see the half-kilometer space rock. CNN has some tips on the best method and time to look. From the article: "The best chance for viewing will be from 8 p.m. ET Monday to 1 a.m. ET Tuesday. Asteroid 2004 BL86 is large, and it will brighten, but nonetheless will not be observable with the naked eye. Some astronomy websites say a pair of binoculars could do the trick, but Sky & Telescope recommends at least a 3- or 4-inch diameter telescope. 'One good technique for fast-movers like 2004 BL86 is to identify and lock onto a star along its path,' Sky & Telescope senior editor Kelly Beatty says. 'Then just watch at the time that the asteroid is predicted to pass by that particular star.'"

An anonymous reader sends word of this biotech breakthrough. "Univ. of California, Irvine (UC Irvine) and Australian chemists have figured out how to unboil egg whites—an innovation that could dramatically reduce costs for cancer treatments, food production and other segments of the $160 billion global biotechnology industry, according to findings published in ChemBioChem. 'Yes, we have invented a way to unboil a hen egg,' said Gregory Weiss, UCI professor of chemistry and molecular biology & biochemistry. 'In our paper, we describe a device for pulling apart tangled proteins and allowing them to refold. We start with egg whites boiled for 20 min at 90 C and return a key protein in the egg to working order.'"

StartsWithABang writes The history of the Universe happened in a well-known order: inflation ends, matter wins out over antimatter, the electroweak symmetry breaks, antimatter annihilates away, atomic nuclei form, then neutral atoms, stars, galaxies, and eventually us. But scientists and science magazines often publish timelines of the Universe with incredibly precise times describing when these various events occur. Here's how we arrive at those values, along with the rarely-publicized uncertainties.

The settlement opens doors for SpaceX to compete with United Launch Alliance (ULA) for launch of spy satellites. ULA is a joint Boeing-Lockheed venture – the only private player to have received clearance for launching black ops satellites.

BarbaraHudson (3785311) writes "Researchers were startled to find fish, crustaceans and jellyfish investigating a submersible camera after drilling through nearly 2,500 feet (740 meters) of Antarctic ice. The swimmers are in one of the world's most extreme ecosystems, hidden beneath the Ross Ice Shelf, roughly 530 miles (850 kilometers) from the open ocean. "This is the closest we can get to something like Europa," said Slawek Tulaczyk, a glaciologist at the University of California, Santa Cruz and a chief scientist on the drilling project.

SternisheFan (2529412) writes with this story at the Verge about an approach being considered by NASA to overcome some of the difficulties in moving a wheeled or multi-legged ground vehicle around the surface of Mars, which has proven to be a difficult task. Rover teams still have a tough time with the Martian surface even though they're flush with terrestrial data. The alien surface is uneven, and ridges and valleys make navigating the terrain difficult. The newest solution proposed by JPL is the Mars Helicopter, an autonomous drone that could 'triple the distances that Mars rovers can drive in a Martian day,' according to NASA. The helicopter would fly ahead of a rover when its view is blocked and send Earth-bound engineers the right data to plan the rover's route.

Pushing further into Big Data, Microsoft on Friday announced it's buying Revolution Analytics, the top commercial provider of software and services for the open-source R programming language for statistical computing and predictive analytics. "By leveraging Revolution Analytics technology and services," blogged Microsoft's Joseph Sirosh, "we will empower enterprises, R developers and data scientists to more easily and cost effectively build applications and analytics solutions at scale." Revolution Analytics' David Smith added, "Now, Microsoft might seem like a strange bedfellow for an open-source company [RedHat:Linux as Revolution Analytics:R], but the company continues to make great strides in the open-source arena recently." Now that it has Microsoft's blessing, is it finally time for AP Statistics to switch its computational vehicle to R?

Americans Support Mandatory Labeling of Food That Contains DNA 338

from the pure-sugar-all-the-time dept.
HughPickens.com writes Jennifer Abel writes at the LA Times that according to a recent survey (PDF), over 80% of Americans says they support "mandatory labels on foods containing DNA," roughly the same number that support the mandatory labeling of GMO foods "produced with genetic engineering." Ilya Somin, writing about the survey at the Washington Post, suggested that a mandatory label for foods containing DNA might sound like this: "WARNING: This product contains deoxyribonucleic acid (DNA). The Surgeon General has determined that DNA is linked to a variety of diseases in both animals and humans. In some configurations, it is a risk factor for cancer and heart disease. Pregnant women are at very high risk of passing on DNA to their children."

The report echoes a well-known joke/prank wherein people discuss the dangers of the chemical "dihydrogen monoxide" also known as hydrogen oxide and hydrogen hydroxide. Search online for information about dihydrogen monoxide, and you'll find a long list of scary-sounding and absolutely true warnings about it: the nuclear power industry uses enormous quantities of it every year. Dihydrogen monoxide is used in the production of many highly toxic pesticides, and chemical weapons banned by the Geneva Conventions. Dihydrogen monoxide is found in all tumors removed from cancer patients, and is guaranteed fatal to humans in large quantities and even small quantities can kill you, if it enters your respiratory system. In 2006, in Louisville, Kentucky, David Karem, executive director of the Waterfront Development Corporation, a public body that operates Waterfront Park, wished to deter bathers from using a large public fountain. "Counting on a lack of understanding about water's chemical makeup," he arranged for signs reading: "DANGER! – WATER CONTAINS HIGH LEVELS OF HYDROGEN – KEEP OUT" to be posted on the fountain at public expense.

Taco Cowboy writes with this excerpt from Space.com: On Monday (Jan. 19), the Chinese Academy of Sciences (CAS) and the European Space Agency (ESA) issued a call for proposals for a robotic space mission that the two organizations will develop jointly. "The goal of the present Call is to define a scientific space mission to be implemented by ESA and CAS as a cooperative endeavor between the European and Chinese scientific communities," ESA officials wrote in a statement Monday. "The mission selected as an outcome of the present Joint Call will follow a collaborative approach through all the phases: study, definition, implementation, operations and scientific exploitation." The call envisions a low-budget mission, saying that ESA and CAS are each prepared to contribute about 53 million euros (U.S. $61.5 million at current exchange rates). The spacecraft must weigh less than 661 lbs. (300 kilograms) at launch and be designed to operate for at least two to three years, ESA officials wrote in the call for proposals. All proposals are due by March 16, and the peer-review process will start in April. Mission selection is expected to occur in late 2015, followed by six years of development, with a launch in 2021.

Scientists Slow the Speed of Light 139

Posted by Soulskill
from the lazy-particles dept.
lightbox32 sends news that scientists have found a way to slow individual photons within a beam of light. Their work was published today in Science Express (abstract, pre-print). The researchers liken a light beam to a team of cyclists — while the group as a whole moves at a constant speed, individual riders may occasionally drop back or move forward. They decided to focus on the individual photons, rather than measuring the beam as a whole. The researchers imposed a particular pattern on a photon, then raced it against another photon, and found that the two arrived at their destination at slightly different times. The work demonstrates that, after passing the light beam through a mask, photons move more slowly through space. Crucially, this is very different to the slowing effect of passing light through a medium such as glass or water, where the light is only slowed during the time it is passing through the material—it returns to the speed of light after it comes out the other side. The effect of passing the light through the mask is to limit the top speed at which the photons can travel.

Zothecula writes: If you're a smoker who's trying to quit, you may recall hearing about vaccines designed to cause the body's immune system to treat nicotine like a foreign invader, producing antibodies that trap and remove it before it's able to reach receptors in the brain. It's a fascinating idea, but according to scientists at California's Scripps Research Institute, a recent high-profile attempt had a major flaw. They claim to have overcome that problem (abstract), and are now developing a vaccine of their own that they believe should be more effective.

Should Disney Require Its Employees To Be Vaccinated? 652

HughPickens.com writes According to Joanna Rothkopf Disneyland is already a huge petri dish of disease with tired children wiping their snot faces on Goofy and then riding log flumes through mechanized rivers filled with the backwash of thousands of other sweaty, unwashed, weeping toddlers. Now John Tozzi reports at Businessweek that five workers at Disneyland have been diagnosed with measles in an outbreak that California officials trace to visitors at the theme park in mid-December. The measles outbreak is a publicity nightmare for Disney and the company is urging its 27,000 workers at the park to verify that they're inoculated against the virus, and the company is offering tests and shots on site for workers who are unvaccinated. One thing Disney won't do, however, is require workers to get routine vaccinations as a condition of employment. Almost no companies outside the health-care industry do. "To make things mandatory just raises a lot of legal concerns and legal issues," says Rob Niccolini. Disney has been working with public health officials, and they've already put some employees on paid leave until medically cleared. "They recognized that they were just a meeting place for measles," says Gilberto Chávez. "And they are quite concerned about doing what they can to help control the outbreak."

It wasn't until they corrected the flawed primary mirror and installed an upgraded camera — the Wide Field Planetary Camera 2 (WFPC2) — that the Universe truly came into focus. From 1993 to 2009, this workhorse camera literally changed our view of the Universe, and we're pushing even past those limits today.

New Advance Confines GMOs To the Lab Instead of Living In the Wild 128

BarbaraHudson (3785311) writes In Jurassic Park, scientists tweak dinosaur DNA so that the dinosaurs were lysine-deficient in order to keep them from spreading in the wild. Scientists have taken this one step further as a way to keep genetically modified E. coli from surviving outside the lab. In modifying the bacteria's DNA to thwart escape, two teams altered the genetic code to require amino acids not found in nature. One team modified the genes that coded for proteins crucial to cell functions so that that produced proteins required the presence of the synthetic amino acid in the protein itself. The other team focused on 22 genes deemed essential to a bacterial cell's functions and tied the genes' expression to the presence of synthetic amino acids. For the bacteria to survive, these synthetic amino acids had to be present in the medium on which the bacteria fed. In both cases, the number of escapees was so small as to be undetectable."

The Paradoxes That Threaten To Tear Modern Cosmology Apart 229

Posted by samzenpus
from the nobody-knows dept.
KentuckyFC writes Revolutions in science often come from the study of seemingly unresolvable paradoxes. So an interesting exercise is to list the paradoxes associated with current ideas in science. One cosmologist has done just that by exploring the paradoxes associated with well-established ideas and observations about the structure and origin of the universe. Perhaps the most dramatic of these paradoxes comes from the idea that the universe must be expanding. What's curious about this expansion is that space, and the vacuum associated with it, must somehow be created in this process. And yet nobody knows how this can occur. What's more, there is an energy associated with any given volume of the universe. If that volume increases, the inescapable conclusion is that the energy must increase as well. So much for conservation of energy. And even the amount of energy associated with the vacuum is a puzzle with different calculations contradicting each other by 120 orders of magnitude. Clearly, anybody who can resolve these problems has a bright future in science but may also end up tearing modern cosmology apart.
