Earlier cancer diagnosis by detecting biomarkers in urine Nanoparticles amplify tumor signals, making them much easier to detect December 19, 2012 These nanoparticles created by MIT engineers can act as synthetic biomarkers for disease. The particles (brown) are coated with peptides (blue) that are cleaved by enzymes (green) found at the disease site. The peptides then accumulate in the urine, where they can be detected using mass spectrometry. (Credit: Justin H. Lo) Specific proteins secreted by cancer cells circulating in the bloodstream could help diagnose cancer earlier, but the q... mais »

First map of how the brain organizes everything we seeDecember 20, 2012 These sections of a semantic-space map show how some of the different categories of living and non-living objects that we see are related to one another in the brain’s “semantic space” (credit: Shinji Nishimoto, An T. Vu, Jack Gallant/Neuron) How do we make sense of the thousands of images that flood our retinas each day? Scientists at the University of California, Berkeley, have found that the brain is wired to organize all the categories of objects and actions that we see, and they have created the first intera...mais »

Mayo Clinic study unmasks regulator of healthy life span Promising target for aging disorders and cancer December 20, 2012 A new series of studies in mouse models by Mayo Clinic researchers uncovered that the aging process is characterized by high rates of whole-chromosome losses and gains in various organs, including heart, muscle, kidney and eye, and demonstrate that reducing these rates slows age-related tissue deterioration and promotes a healthier life span. “We’ve known for some time that reduced levels of BubR1 are a hallmark of aging and correspond to age-related conditions, i... mais »

MIT researchers discover a new kind of magnetism ‘Quantum spin liquid’ could have applications in new computer memory storage December 21, 2012 *[+]* MIT physicists grew this pure crystal of herbertsmithite in their laboratory. This sample, which took 10 months to grow, is 7 mm long (just over a quarter-inch) and weighs 0.2 grams. (Credit: Tianheng Han/MIT) MIT researchers have demonstrated experimentally the existence of a fundamentally new kind of magnetic behavior called a *quantum spin liquid* (QSL),adding to the two previously known states of magnetism. *Ferromagnetism* — the simp... mais »

Our Family Christmas, RescindedBy HEATHER HAVRILESKYPublished: December 21, 2012 Comment Enlarge This ImageSeveral years ago, my mother announced that she was spending Christmas in Egypt with friends.

One Nation Under God?By MOLLY WORTHENPublished: December 22, 2012 Enlarge This Image THIS week millions of “Chreasters” — Americans who attend church only on Christmas and Easter — will crowd into pews to sing carols and renew their vague relationship with the Christian God. This year, there may be fewer Chreasters than ever. A growing number of “nones” live in our midst: those who say they have no religious affiliation at all. An October Pew Research Center poll revealed that they now account for 20 percent of the population, up from 16 percent in 2008. Valero Doval Avoiding church ... mais »
