Scientists uncover new class of mammalian genes with key functions
A research team at the Broad Institute of Harvard and MIT and Beth Israel Deaconess Medical Center has uncovered a vast new class of previously unrecognized mammalian genes that do not encode proteins, but instead function as long RNA molecules. Their findings, presented in the Feb. 1 advance online issue of the journal Nature, demonstrate…

Stem Cell Research: The Quest Resumes
“After eight years of political ostracism, stem-cell scientists like Harvard’s Douglas Melton are coming back into the light — and making discoveries that may soon bring lifesaving breakthroughs. Scientific inspiration can come from anywhere — a person, an event, even an experiment gone awry. But perhaps nothing can drive innovation more powerfully than the passion…

The genes in your congeniality:
Can’t help being the life of the party? Maybe you were just born that way. Researchers at Harvard and the University of California, San Diego, have found that our place in a social network is influenced in part by our genes, according to new findings published in the Proceedings of the National Academy of Sciences.…

Implants mimic infection to rally immune system against tumors
Harvard bioengineers have shown that small plastic disks impregnated with tumor-specific antigens and implanted under the skin can reprogram the mammalian immune system to attack tumors. The research — which rid 90 percent of mice of an aggressive form of melanoma that would usually kill the rodents within 25 days — represents the most effective…

Hotter seasons coming earlier, research finds
An analysis of global temperatures between 1850 and 2007 has illuminated some climate change details, showing that winter temperatures have risen more rapidly than summer temperatures and that the seasons are coming nearly two days earlier than they were 50 years ago. Perhaps most worrisome, however, is that none of the dozens of computerized climate…

Topical treatment wipes out herpes with RNAi
Harvard Medical School researchers have succeeded in developing a topical treatment that, in mice, wipes out herpes virus, one of the most intractable sexually transmitted human diseases. Judy Lieberman, professor of pediatrics and a senior investigator at the Immune Disease Institute, has overseen the development of the treatment that uses RNA interference, or RNAi, to…

Transit search finds super-Neptune
Astronomers at the Harvard-Smithsonian Center for Astrophysics havediscovered a planet somewhat larger and more massive than Neptuneorbiting a star 120 light-years from Earth. While Neptune has a diameter3.8 times that of Earth and a mass 17 times Earth’s, the new world(named HAT-P-11b) is 4.7 times the size of Earth and has 25 Earthmasses. HAT-P-11b was…

Researchers find new molecule to block ‘Hedgehog’ signaling in cancer, development
Researchers have achieved a feat drug developers had thought difficult, if not impossible, discovering a compound that blocks the functioning of a key developmental protein by binding to an “undruggable” target — an advance that may provide a new avenue to fight skin, pancreatic, prostate, and other cancers. A team led by Stuart Schreiber, the…

Surgical safety checklist drops deaths and complications by more than one-third
A group of hospitals in eight cities around the globe has successfully demonstrated that the use of a simple surgical checklist during major operations can lower the incidence of deaths and complications by more than one-third. The rate of major complications in the study operating rooms fell from 11 percent in the baseline period to…

Spinal tap unnecessary for most babies with uncomplicated febrile seizures
When babies develop a fever high or abrupt enough to cause a seizure, frightened parents often rush them to the emergency room, where their workup frequently includes a lumbar puncture (spinal tap) to rule out bacterial meningitis. Now, in the largest study to date, Harvard researchers at Children’s Hospital Boston find that this uncomfortable procedure…

Researchers control the assembly of nanobristles into helical clusters
From the structure of DNA to nautical rope to distant spiral galaxies, helical forms are as useful as they are abundant in nature and manufacturing alike. Researchers at Harvard’s School of Engineering and Applied Sciences (SEAS), the Wyss Institute for Biologically Inspired Engineering, and the Radcliffe Institute for Advanced Study have discovered a way to…

Researchers see exotic force for first time
For the first time, researchers have measured a long-theorized force that operates at distances so tiny they’re measured in billionths of a meter, which may have important applications in nanotechnology as scientists and engineers seek new ways to create devices far too small for the eye to see. The advance, by researchers by Harvard and…

Obesity: Reviving the promise of leptin
The discovery more than a decade ago of leptin, an appetite-suppressing hormone secreted by fat tissue, generated headlines and great hopes for an effective treatment for obesity. But hopes dimmed when it was found that obese people are unresponsive to leptin due to development of leptin resistance in the brain. Now, Harvard researchers at Children’s…

Antacid medication in pregnancy may increase childhood asthma
Children of mothers who took acid-suppressive drugs during pregnancy had a 1.5 times higher incidence of asthma when compared with children who were not exposed to the drugs in utero, finds a large population-based study by researchers at Children’s Hospital Boston. The findings, accompanied by an editorial, appear online in “Early View” in the journal…

Religion in the vernacular
In 1215, Pope Innocent III convened the Fourth Council of the Lateran, a religious convocation that laid out to hundreds of bishops, abbots, priors, and Christian patriarchs 70 new decrees. One enjoined the clergy to stop frequenting taverns, engaging in trials by combat, hunting, and practicing what might be called noncelibate habits.

Scholar asks: ‘How can we know the spectator from the dance?’
When Yvonne Rainer and her fellow dancers took to the stage in the early 1960s, their performances were like nothing American audiences had ever seen. First, there were no costumes. Performers wore T-shirts, casual pants, and sneakers. In place of elaborate leaps and twirls, the dancers engaged in everyday movements like running, climbing, and even…
