Results of AIDS vaccine trial ‘weak’ in second analysis
In an editorial accompanying the journal paper, Dr. Raphael Dolin of the Beth Israel Deaconess Medical Center in Boston said the overall findings were nonetheless "of potentially great importance to the field of HIV research" because they might yield information about the kinds of immune responses necessary to provide protection against the virus….
A Cancer Visible To The Naked Eye, But Doctors Aren’t Looking
“We were very, very surprised,” Geller recalls. “About three-quarters of them were never trained in the skin cancer exam, and more than half never once practiced the examination during their primary care residency.” Geller, who’s a senior research scientist at the Harvard School of Public Health, says those high levels of inexperience are really worrisome. Many of those medical residents surveyed are going to become primary care doctors — and they should be able to identify a malignant melanoma when they see one.
From stem cells to heart muscle
A team of Harvard Stem Cell Institute researchers at Massachusetts General Hospital and collaborators at Harvard’s School of Engineering and Applied Sciences has taken a giant step toward possibly using human stem cells to repair damaged hearts.
Autism’s genetic roots examined in new government-funded study
Researchers at Harvard University and Children's Hospital Boston will sequence the genomes of at least 85 people diagnosed with autism in a bid to tease out the genetic basis for some cases of the neuropsychiatric disorder.
Quest for a Long Life Gains Scientific Respect
In mice, sirtuin activators are effective against lung and colon cancer, melanoma, lymphoma, Type 2 diabetes, cardiovascular disease and Alzheimer’s disease, said David Sinclair, a Harvard Medical School researcher and co-founder of Sirtris. The drugs reduce inflammation, and if they have the same effects in people, could help combat many diseases that have an inflammatory component, like irritable bowel syndrome and glaucoma….
Around the Schools: Harvard School of Public Health
A new center focusing on mathematical modeling of drug resistance, seasonal infectious diseases, and intervention allocation will be established at the Harvard School of Public Health.
Medical grants a boon for Mass.
Massachusetts biomedical researchers are seeing a windfall from federal stimulus money, with the state receiving more in grants from the National Institutes of Health than all others but California.
H1N1 influenza advice for Commencement week visitors
While at Harvard, should you experience any symptoms consistent with H1N1 flu, you should contact Harvard University Health Services (HUHS).
Biology department evolves at FAS
Earlier this month, the Faculty of Arts and Sciences (FAS) made official what scientists worldwide have known for years: Harvard is a hotbed of research and teaching in the field of human evolutionary biology — the study of why we’re the way we are.
Embryo’s heartbeat drives blood stem cell formation
Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood. Two groups of Harvard Stem Cell Institute (HSCI) researchers from Children’s Hospital Boston (Children’s) and Brigham and Women’s Hospital (BWH) — presenting multiple lines of evidence from zebrafish, mice, and mouse embryonic stem cells — provide an intriguing answer: A beating heart and blood flow are necessary for development of the blood system, which relies on mechanical stresses to cue its formation.
