Physicists have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results represent the largest number of particles that have ever been mutually entangled experimentally.
It’s believed that wolves once roamed the southeastern U.S. before they were eliminated by overhunting and habitat loss. Now, the region has a new top dog, the coyote, which may fill the role once played by wolves.
How did the chicken cross the sea? No, that’s not a joke. A team has studied the mysterious ancestry of the feral chicken population that has overrun the Hawaiian Island of Kauai. Their results may aid efforts to curtail the damage of invasive species in the future, and help improve the biosecurity of domestic chicken breeds.
New research concludes that there is limited evidence to show that xylitol is effective in preventing dental cavities in children and adults. Xylitol is a natural sweetener that is widely promoted globally, and can be found in wide range of everyday products including sugar-free chewing gum, toothpaste, gels, lozenges and sweets.
A plastic used in filters and tubing has an unusual trait: it can produce electricity when pulled or pressed. This ability has been used in small ways, but now researchers are coaxing fibers of the material to make even more electricity for a wider range of applications from green energy to "artificial muscles."
Newly published research details a discovery explaining why the 100 million Americans estimated to be taking prescription and over-the-counter antacid and heartburn medications may be at an increased risk of bone fractures.
Orchestrated costume changes make it possible for certain nasty microbes to outsmart the immune system, which would otherwise recognize them by the telltale proteins they wear. By taking the first detailed look at how one such parasite periodically assumes a new protein disguise during a long-term infection, research challenges many assumptions about one of the best-known examples of this strategy.
“Create a password” is a prompt familiar to anyone who has tried to buy a book from Amazon or register for a Google account. Equally familiar is that red / yellow / green bar that rates the new password’s strength. But when those meters give the go-ahead to passwords like Password1+, their effectiveness is called into question.
An analysis found that the risks of drinking raw (unpasteurized) cow’s milk are significant. Consumers are nearly 100 times more likely to get foodborne illness from drinking raw milk than pasteurized milk. In fact, the work found raw milk was associated with more than half of all milk-related foodborne illness, even though only an estimated 3.5 percent of the U.S. population consumes it.
Scientific literature traces manhole explosions back nearly a century, but a series of such incidents in Indianapolis has authorities looking for a quick solution. A combination of power system design, winter road salt, older electrical cable insulation and basic chemistry have triggered underground explosions in older downtowns, launching 350-pound manhole covers high in the air.
Effective lab-based tests are required to eliminate the need for animal testing in assessing the toxicological effects of inhaled chemicals and safety of medicines. A 3-D model of human respiratory tissue has been shown to be an effective platform for measuring the impact of chemicals, like those found in cigarette smoke, or other aerosols, on the lung.
A pocket-sized device that can rapidly determine the sequence of an organism's DNA has shown its potential in disease detection. In the first analysis of its kind, researchers were able to use the device to accurately identify a range of closely related bacteria and viruses within six hours, demonstrating the potential for this technology to be used as a mobile diagnostic clinic during outbreaks.
Antimicrobial resistance is a major health care problem worldwide. In the first installment of a new series in The BMJ, a professor asks why authorities are approving drugs with little evidence they do anything to tackle the problem of antimicrobial resistance.
Researchers have developed a county-by-county map of the U. S. that tells a story of land cover and development across the nation, and could provide a framework for future development. They integrated satellite data with census population data and produced a map that depicts— in vivid shades of red and green— how each county's developed land compares to that of counties with similar populations.
Laboratory Equipment’s scientist of the week is Diane Favro from UCLA. Favro and a team recreated Augustan Rome algorithmically using a technique known as procedural modeling. According to legend, the founder of the Roman Empire, Augustus, boasted, “I found Rome a city of bricks and left it a city of marble.” Favro wanted to know if he telling the truth or making an empty claim.
