A joint effort of citizen scientists and professional astronomers has led to the first reported case of a planet orbiting twin suns that in turn is orbited by a second distant pair of stars.
Aided by volunteers using the Planethunters.org website, a Yale-led international team of astronomers identified and confirmed discovery of the phenomenon, called a circumbinary planet in a four-star system.
Only six planets are known to orbit two stars, according to researchers, and none of these are orbited by distant stellar companions. (more…)
TeselaGen’s DNA construction technology makes genetic engineering cheaper and faster.
Sequencing, splicing and expressing DNA may seem to be the quintessence of cutting-edge science—indeed DNA manipulation has revolutionized fields such as biofuels, chemicals and medicine. But in fact, the actual process can still be tedious and labor-intensive, something Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Nathan Hillson learned the hard way.
After struggling for two days to design a protocol to put together a genetic circuit with 10 pieces of DNA—using a spreadsheet as his primary tool—he was dismayed to discover that an outside company could have done the whole thing, including parts and labor, for lower cost than him ordering the oligonucleotides himself. “I learned two things: one, I never wanted to go through that process again, and two, it’s extremely important to do the cost-effectiveness calculation,” said Hillson, a biochemist who also directs the synthetic biology program at the Berkeley Lab-led Joint BioEnergy Institute (JBEI). “So that was the genesis of the j5 software. This is the perfect thing to teach a computer to do.” (more…)
Paper describes new method to understand sources of noise in gene-expression
Abhyudai Singh, assistant professor of electrical and computer engineering at the University of Delaware, describes a new method to understand sources of “noise” in gene-expression that create variability in protein levels in a paper published in Molecular Systems Biology, a publication of Nature, on Aug. 28.
This noise is expressed as variability in the levels of proteins/mRNAs in a cell. (more…)
Windows Azure offered Pottermore the flexibility required to build a massively scalable website in just three months.
REDMOND, Wash. – June 6, 2012 – Eagerly awaiting the launch of Pottermore (www.pottermore.com), the website based on the popular Harry Potter stories, Brittany Talbot and her sister, Priscilla, raced to sign up when the site went live on April 14, 2012.
They weren’t alone. Within hours, thousands of Harry Potter fans were flooding the site and just two weeks after the Pottermore website went live, it received one billion page views, making it one of the most popular sites on the Web. To date, 10 million unique visitors have visited the site, with 25,000 new users signing up every day.
With Harry Potter one of the largest entertainment phenomena of all time, fans of all ages couldn’t wait to experience the world-famous stories, social, and interactive experiences the site offered. “I like being able to go up there and do potions and spells, and walk around where Harry was,” Brittany says. “I read the first book in the first week because I was so excited.” (more…)
ANN ARBOR, Mich.— Popular firewall technology designed to boost security on cellular networks can backfire, unwittingly revealing data that could help a hacker break into Facebook and Twitter accounts, a new study from the University of Michigan shows.
The researchers also developed an Android app that tells phone users when they’re on a vulnerable network. They will present their work May 22 at the IEEE Symposium on Security and Privacy in San Francisco. (more…)
Famous 1848 case of man who survived a terrible accident has modern parallel
Poor Phineas Gage. In 1848, the supervisor for the Rutland and Burlington Railroad in Vermont was using a 13-pound, 3-foot-7-inch rod to pack blasting powder into a rock when he triggered an explosion that drove the rod through his left cheek and out of the top of his head. As reported at the time, the rod was later found, “smeared with blood and brains.”
Miraculously, Gage lived, becoming the most famous case in the history of neuroscience — not only because he survived a horrific accident that led to the destruction of much of his left frontal lobe but also because of the injury’s reported effects on his personality and behavior, which were said to be profound. Gage went from being an affable 25-year-old to one that was fitful, irreverent and profane. His friends and acquaintances said he was “no longer Gage.” (more…)
*N.Y., L.A., Miami, San Francisco, D.C. Top List; Maricopa, Ariz. Rising*
COLLEGE PARK, Md. – Nearly a third of all terrorist attacks from 1970 to 2008 occurred in just five metropolitan U.S. counties, but events continue to occur in rural areas, spurred on by domestic actors, according to a report published today by researchers in the National Consortium for the Study of Terrorism and Responses to Terrorism (START), a Department of Homeland Security Science and Technology Center of Excellence based at the University of Maryland.
The research was conducted at Maryland and the University of Massachusetts-Boston. (more…)
More Asian Pacific Americans hold public office in the United States than at any other time in U.S. history, a sign of the community’s growing engagement with the political process, according to a newly released political almanac published by UCLA’s Asian American Studies Center.
The 14th edition of the National Asian Pacific American Political Almanac, first published in 1976, contains information on all 3,000 current elected and appointed officials. It also analyzes political trends and makes electoral projections of the nation’s 17 million Asian Pacific Americans. (more…)
