Weight gain in pregnancy linked to overweight in kids
Pregnant women who gain excessive or even appropriate weight, according to current guidelines, are four times more likely than women who gain inadequate weight to have a baby who becomes overweight in early childhood. These findings are from a new study at the Department of Ambulatory Care and Prevention of Harvard Medical School (HMS) and…

Warming may not spark tree growth
A bright spot in the gloomy global warming picture has been scientists’ predictions that at least some carbon dioxide will be removed from the atmosphere by a burst of growth from tropical forests. New research from the Arnold Arboretum, however, questions that prediction, finding that trees in two forests on opposite sides of the world…

Smile and the world smiles with you, but why?
“We are connected in ways we don’t consciously know, but which are absolutely essential for communication,” said psychologist and author Daniel Goleman at a March 14 talk on social intelligence sponsored by the John F. Kennedy School of Government’s Center for Public Leadership. “There is a subterranean emotional economy that’s part of any interaction.”

Noninfectious pathway for HIV found by HSPH team
HIV is a crafty virus. It attacks the body by invading and taking over the very cells meant to protect humans from infection. Hiding within cells such as macrophages and lymphocytes, the virus uses the body’s natural machinery to replicate itself, destroying the immune system and leaving patients open to a range of debilitating and…

Stem cells, through a religious lens
Representatives of three of the world’s major religions tangled over the beginnings of human life, the disposal of surplus embryos from in vitro fertilization clinics, and the conduct of embryonic stem cell research Wednesday (March 14) at Harvard Divinity School. Panelists at the event, representing Christianity, Judaism, and Islam, each briefly presented their faith’s teachings…

Jane Goodall: A life in the field
As a girl in England, Jane Goodall had a toy chimpanzee named Jubilee — a harbinger of the primatologist she was to become and of the jubilant audiences that greet her at every turn in adulthood. Beginning in 1960, her groundbreaking studies of chimpanzees in the African wild led to a series of revelations that…

Study questions ‘cancer stem cell’ hypothesis in breast cancer growth
A Dana-Farber Cancer Institute study challenges the hypothesis that “cancer stem cells” — a small number of self-renewing cells within a tumor — are responsible for breast cancer progression and recurrence, and that wiping out these cells alone could cure the disease.

Can science, religion coexist in peace?
Almost 14 billion years after the big bang, and 3.5 billion years since the first bacteria appeared on Earth, humans occupy just one branch of the tree of life. We share an evolutionary limb with other eukaryotes, creatures whose membrane-bound cells carry genetic material. Our biological neighbors developed over time just as we did, by…

Indonesia’s strategies to fight bird flu run afoul of reality
If Indonesia is able to execute a comprehensive bird flu plan written by the government, it will take great strides toward controlling the outbreak in the sprawling island nation, a visiting professor who has studied the region said Friday (March 9). Unfortunately, there’s little chance of that happening.

Sleep found to repair and reorganize the brain
Most of us do it every night but we don’t know why. If you miss too many nights, it might kill you. We know why we eat, drink, breathe, and move around, but no one can explain why we need to sleep. What does seven or eight hours of snoozing really do for us? Van…

HSPH study suggests taking wraps off drug safety data
For years, pharmaceutical companies have sought to restrict public access to drug safety data collected in clinical trials on the basis that it is proprietary information, arguing that competitors could use that information in the development of their own products. However, a number of recent cases of drugs found to have dangerous side effects after…

Despite their heft, many dinosaurs had surprisingly tiny genomes
They might be giants, but many dinosaurs apparently had genomes no larger than those of a modern hummingbird. So say scientists who’ve linked bone cell and genome size among living species and then used that new understanding to gauge the genome sizes of 31 species of extinct dinosaurs and birds, whose bone cells can be…

I know just how you feel
When people talk with psychotherapists, the best results occur if both feel similar emotions, when both “like” each other. But do most therapists really connect with patients this way? No one has ever tried to directly measure the biology of empathy between the two.

Seeing the forest, from the trees
Alain Houle thinks higher-status chimpanzees likely feed on more, higher-quality fruit — found higher up in the tree — than lower-status chimpanzees, which leads to the chimps being in better physical shape and greater breeding success. “I thought I’d be killed,” Houle said later. “They climbed up, looked at me, barked at me, and then…

Over-the-counter pain relievers increase the risk of high blood pressure in men
Researchers from Brigham and Women’s Hospital (BWH) have found that the three most commonly used drugs in the United States, acetaminophen, ibuprofen, and aspirin, increase the risk of developing high blood pressure in middle-aged men. These findings are published in the Feb. 26 issue of the Archives of Internal Medicine.
