Altered states of consciousness through yoga, mindfulness more common than thought and mostly beneficial, study finds — though clinicians ill-equipped to help those who struggle
Researchers have identified a key reason why people make mistakes when they try to predict what they will like. When predicting how much they will enjoy a future experience, people tend to compare it to its alternatives — that is, to the experiences they had before, might have later, or could be having in the present moment. But when people actually have the experience, they tend not to think about these alternatives and their experience is relatively unaffected by them.
Harvard Stem Cell Institute (HSCI) and Massachusetts General Hospital (MGH) researchers have taken a major step toward eventually being able to reprogram adult cells to an embryonic stem cell-like state without the use of viruses or cancer-causing genes.
Shedding new light on the cognitive rift between humans and animals, a Harvard University scientist has synthesized four key differences in human and animal cognition into a hypothesis on what exactly differentiates human and animal thought.
During the course of the presidential nomination campaigns, some candidates’ health care plans have been described as “socialized medicine.” Historically, that phrase has been used to criticize health reform proposals in the United States.
Despite all the progress and promise of modern medicine, most of the world is still struggling to get the fundamentals of medical care: simple diagnostic tests, affordable medicines, and efficient…
Useful genetic maps showing the inner workings of drug-resistant malaria parasites, and where they live around the world, are being created as part of a major drive against the persistent tropical disease.
How to lose weight and keep it off? Consume fewer calories and burn more calories than you consume, says Rena Wing, director of the Weight Control & Diabetes Research Center at…
Three studies presenting newly identified genetic variants that are associated with increased susceptibility to prostate cancer were published recently (Feb. 10) on the advance online site of Nature Genetics. The 10 gene variants double the number of known variants associated with risk of the disease and are the result of genomewide association studies.
Elevated levels of anxiety may cause women with ductal carcinoma in situ (DCIS), the most common form of noninvasive breast cancer, to overestimate their risk of recurrence or dying from breast cancer, suggests a study led by researchers at Harvard-affiliated Dana-Farber Cancer Institute in Boston.
By looking at infant brain activity, researchers have found that babies as young as 3 months old are sensitive to differences in numerical quantity. Additionally, the scientists were able to see that babies process information about objects and numbers in different, dissociated parts of the brain, which is also the case in older children and in adults.
It was close to midnight one day this week in Durban, South Africa, when Harvard AIDS researcher Bruce D. Walker switched on his computer and made a visit to 104 Mt. Auburn St. in Cambridge.
Researchers at Brigham and Women’s Hospital (BWH), the Harvard School of Public Health (HSPH), Harvard Medical School (HMS) and Partners In Health (PIH) have received a grant of $14 million over five years from the National Institutes of Health to study multi-drug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB). The goal of the project is to better understand the development and transmission of drug-resistant tuberculosis and to identify practical approaches to reduce the public health burden created by this disease.
Money, love, health, innocence or guilt — even finding the right wine. Who doesn’t want to know more? “Real-Life Statistics: Your Chance for Happiness (or Misery),” offered this semester by Harvard’s Department of Statistics, will explore the critical tools to make good judgments in matters large and small.
Harvard neuroscientist Venkatesh N. Murthy has a sunny second-floor office on Divinity Avenue, where he is a professor in Harvard’s Department of Molecular and Cellular Biology. In one corner is a set of weights and a soccer ball — both untouched in over a year, he said, because of an intensely busy schedule.
In nearly every country in the world, there is a shortage of kidneys for transplantation. In the United States, around 73,000 people are on waiting lists to receive a kidney. Yet 4,000 die every year before the lifesaving organ is available.

It’s increasingly believed among scientists that nearly every cancer contains small populations of highly dangerous cells — cancer stem cells — that can initiate a cancer, drive its progression, and create endless copies of themselves. On the theory that targeting these cells might be an effective therapeutic strategy, researchers around the world have begun isolating stem cells from various kinds of cancers. Now, for the first time, researchers at Children’s Hospital Boston and Brigham and Women’s Hospital (BWH) have found a strategy that selectively targets cancer stem cells for destruction, successfully halting one of the deadliest cancers — melanoma — in mice.
Major differences in protocols used to determine brain death; Harvard researchers achieve stem cell milestone; Consortium links chromosome abnormality to autism disorders; Blocking HIV infection; Oral osteoporosis meds appear to reduce the risk of jaw degradation; Six new genetic variants linked to heart-disease risk factor; Gene variation may elevate risk of liver tumor in some patients; Cancer stem cells can be targeted for destruction
People who receive high doses of the chemotherapy drug methotrexate to treat a certain type of brain tumor appear to live longer than people receiving other treatments, according to research published in the Jan. 29 issue of Neurology, the medical journal of the American Academy of Neurology.
While hunting among chimpanzees is a group effort, key males known as “impact hunters” are highly influential within the group. They are more likely to initiate a hunt, and hunts rarely occur in their absence, according to a new study. The findings, which appear in the current issue of Animal Behaviour, shed light on how and why some animals cooperate to hunt for food, and how individual variation among chimpanzees contributes to collective predation.
Risk factors for suicidal thoughts, plans, and attempts are consistent across countries, and include having a mental disorder and being female, younger, less educated, and unmarried. So says new research from Harvard University and World Health Organization (WHO) World Mental Health Survey Initiative. The study examined both the prevalence and the risk factors for suicide across 17 countries, and is the largest, most representative examination of suicidal behavior ever conducted.
Two clinical trials of the novel drug romiplostim (Nplate) show that it significantly improved platelet levels in patients with chronic immune thrombocytopenic purpura (ITP), a hematologic disorder that can cause uncontrolled…
A compound that naturally occurs in grapefruit and other citrus fruits may be able to block the secretion of hepatitis C virus (HCV) from infected cells, a process required to…
Human embryos that are discarded every day as medical waste from in vitro fertilization (IVF) clinics could be an important source of stem cells for research, according to a team…
