Nicotine letdown. No boost from patches, gum in study of quitting success. Nicotine Replacement Therapies May Not Be Effective in Helping People Quit Smoking “This study shows that using NRT [nicotine replacement therapies] is no more effective in helping people stop smoking cigarettes in the long term than trying to quit on one’s own,” said […]

Molecular Motor Struts Like Drunken Sailor To understand how molecular motors work, some researchers are creating animations. Here, each “leg” of a molecular motor called dynein moves as it progresses along a cellular structure called a microtubule. New data suggest that dynein’s walk is even stranger than the one modeled. View its movement in action […]

Multitasking – a medical and mental hazard “During a recent check-up, my doctor snuck a look at her phone a couple times. I don’t think it had anything to do with my health or care, so it was mildly annoying—but I didn’t say anything. After reading a report about a man who almost died because […]

Twelve tips for healthier eating in 2012 It’s not about individual nutrients anymore. For much of the 20th century, nutrition research focused largely on the health risks and benefits of single nutrients. The findings translated into public health messages telling us to reduce fat; limit cholesterol; increase fiber; get more calcium; take vitamins E, C, […]

Reading life’s building blocks. Harvard researchers develop tools to speed DNA sequencing. In a recent Nature Nanotechnology paper, researchers from Harvard demonstrated that nanowire transistors can locally read and amplify the DNA translocation signal from a nearby nanopore./ Image courtesy of Ping Xie, Qihua Xiong, Ying Fang, Quan Qing, and Charles M.

New Leadership Offerings Give HSPH Students Hands-on Practice It’s one thing to understand the public health implications of scientific evidence. It’s quite another to use that information to successfully implement real public health improvements. HSPH student Shaniece Criss participated in the group dynamics workshop The challenge of leaping from theory to practice has prompted the […]

Study Finds Key to Drug Resistance Sophisticated “targeted” drug therapies are improving cancer care by selectively shutting down abnormal growth switches in tumor cells while avoiding toxicity to normal tissues. In some cases, though, tumors that are initially sensitive to these drugs first regress but then activate different, “backup” genetic signals that enable them to […]
Can Brown Rice Slow the Spread of Type 2 Diabetes? The worldwide spike in type 2 diabetes in recent decades has paralleled a shift in diets away from staple foods rich in whole grains to highly refined carbohydrates, such as white rice and refined flours. Now, a group of researchers at Harvard School of Public […]
