One thing certain about the flu is uncertainty, according to Marc Lipsitch, a professor of epidemiology at the Harvard School of Public Health and a prominent authority on the spread…
Opposites may always attract. But they may not remain together long-term. In a counter-intuitive discovery published in the current edition of the journal Nature, researchers from Harvard, the University of California at…
Nearly 45,000 annual deaths are associated with lack of health insurance, according to a new study published online today by the American Journal of Public Health. That figure is about…
Health officials learned enough during the spring’s first wave of swine flu to be confident about managing this fall’s expected second wave, despite a “sense of uneasiness” that hangs over the coming flu season, Harvard School of Public Health Dean Julio Frenk.
One hundred and fifty thousand species down, 1.65 million to go. That is the tally for the online Encyclopedia of Life (www.eol.org/), an ambitious two-year-old project with the goal of nothing less than documenting in one place all of the 1.8 million known living species on Earth and making the information available to everyone with Internet access.
A new analysis of extinct sea creatures suggests that the transition from egg-laying to live-born young opened up evolutionary pathways that allowed these ancient species to adapt to and thrive in open oceans.
A conversation between DNA discoverer James Watson and biologist E.O. Wilson was moderated by Robert Krulwich. They reflected on their lives and careers and talked about the future of biology at Sanders Theatre in Memorial Hall at Harvard University.
The virus responsible for progressive multifocal leukoencephalopathy (PML), a rare brain disease that typically affects AIDS patients and other individuals with compromised immune systems, has been found to be reactivated…
A large international research team has decoded the genome of the notorious organism that triggered the Irish potato famine in the mid-19th century and now threatens this season’s tomato and…
A vivid illustration of natural selection at work: Harvard scientists have found that deer mice quickly evolved lighter coloration after glaciers deposited sand dunes atop what had been much darker soil.
For more than a century, scientists have been using electrical stimulation to explore and treat the human brain. The technique has helped identify regions responsible for specific neural functions and has been used to treat a variety of conditions from Parkinson’s disease to depression. Yet no one has been able to see what actually happens at the cellular level when the brain is electrically prodded.
Even as low-carbohydrate/high-protein diets have proven successful at helping individuals rapidly lose weight, little is known about the diets’ long-term effects on vascular health. Now, a study led by team…
Two of the most powerful approaches to cancer treatment — a stem cell transplant and an immune system-stimulating vaccine — appear to reinforce each other in patients with an aggressive,…
A form of partial epilepsy associated with auditory and other sensory hallucinations has been linked to the disruption of brain development during early childhood, according to a study led by…
While questions still remain about the H1N1 flu’s potential virulence in the coming months, there is little doubt that this particular viral strain will return.
Cells don’t like to be alone. In the early stages of tumor formation, a cell might be pushed out of its normal home environment due to excessive growth. But a…
Scientists at Dana-Farber Cancer Institute have uncovered the mechanism behind a promising new approach to cancer treatment: damaging cancer cells’ DNA with potent drugs while simultaneously preventing the cells from…
The National Institutes of Health has renewed for five years – and $18.1 million – the funding for the Harvard University Center for AIDS Research (Harvard CFAR). Harvard is one…
A multi-institutional team of Boston-area researchers has discovered a chemical that works in mice to kill the rare but aggressive cells within breast cancers that have the ability to seed…
Praveen Kumar Vemula, a postdoctoral researcher in the Karp Lab at Brigham and Women’s Hospital, is one of 13 researchers to receive the Kauffman Foundation Entrepreneurial Postdoctoral Fellowship Award. Vemula…
Regular use of aspirin after colorectal cancer diagnosis may reduce the risk of cancer death, report Harvard researchers at Massachusetts General Hospital (MGH), Dana-Farber Cancer Institute (DFCI) and Brigham and Women’s Hospital. In today’s edition of the Journal of the American Medical Association, the study’s authors also find that the aspirin-associated survival advantage was seen primarily in patients with tumors expressing the COX-2 enzyme, a characteristic of two-thirds of colorectal cancers.
Harvard Stem Cell Institute (HSCI) researchers at Massachusetts General Hospital (MGH) have substantially improved the odds of successfully reprogramming differentiated cells into induced pluripotent stem cells (iPS) by blocking the…
Political and philosophical differences aside, it’s the economic crisis that’s driving the current national health care reform debate. “Every day the president gets an envelope [that] says, ‘Whoa! Bigger [deficit]…
Since evolving to eat other fish, freshwater fish at the top of the food chain have remained relatively unchanged compared with their insect- and snail-eating cousins, according to new research.…
Harvard researchers at Dana-Farber Cancer Institute have shown that they can engineer mouse and human cells to produce brown fat, a natural energy-burning type of fat that counteracts obesity. If…
An analysis of rare genetic disorders in which children lack some genes from one parent suggests that maternal and paternal genes engage in a subtle tug-of-war well into childhood, and…
