Unraveling the secrets of the epilepsy diet
Researchers at Harvard Medical School and Harvard-affiliated Dana-Farber Cancer Institute have identified a protein that plays a key role in the long-mysterious effectiveness of an extremely low-calorie, high-fat, low-carbohydrate diet in suppressing epileptic seizures.
A Harvard graduate student has shown that some Australian and Pacific Island daddy longlegs took an unusual path to their new homes: drifting from the Americas and then island-hopping to their new continental home in Australia.
Harvard research examining the nervous system of Caenorhabditis elegans -- tiny, transparent worms -- suggest a path for investigations that may shed light on disorders such as schizophrenia.
Toxic mercury springs from a hidden source
Environmental scientists at Harvard have discovered that the Arctic accumulation of mercury, a toxic element, is caused by both atmospheric forces and the flow of circumpolar rivers that carry the element north into the Arctic Ocean.

Harvard researchers probe environmental shifts on Martha’s Vineyard, where they document one wooded area’s recovery from a massive die-off and another’s passage into the ocean.
A landmark effort to sequence the genome of the butterfly Heliconius melpomene has revealed that it shares genes that control color patterns with two species that closely mimic its appearance — Heliconius timareta and Heliconius elevatus — suggesting that all three exchange genes as a result of occasional hybridization.
Supermassive black holes snack infrequently, making the recent discovery of a black hole in the act of feeding all the more interesting to astronomers.
Researchers at Harvard-affiliated Massachusetts General Hospital have uncovered a new way that animals detect pathogens, by detecting disruptions of critical cellular processes.
Thinking about health as an investor might
A “proof-of-concept” study that applies financial portfolio theory to federal life science research funding shows that potentially significant gains are available by altering the allocation of funding by the National Institutes of Health.
Taking the long view on infrastructure
“Envision,” a tool developed with backing from the Zofnass Program for Sustainable Infrastructure at GSD, provides a comprehensive framework for governments and industry to evaluate infrastructure projects of all types and sizes based on environmental, economic, and community benefits.
Sharing design, in all its forms
The first Design Fair at the Harvard School of Engineering and Applied Sciences (SEAS) displayed the wealth of ideas that have emerged at SEAS throughout this past academic year.
Flavonoid compound can prevent blood clots
Harvard researchers have shown that a compound called rutin, commonly found in fruits and vegetables and sold over the counter as a dietary supplement, inhibits the formation of blood clots in an animal model of thrombosis.
New tool to battle illegal trade in animals
Harvard’s Center for Geographic Analysis will work with United Nations University on a system that will allow users to track and map wildlife crime, and how it is related to a host of socioeconomic factors.
The whys of religion vs. evolution
University of Chicago evolutionary biologist Jerry Coyne says that dysfunction within American society promotes high levels of religious belief that in turn blocks general acceptance of evolutionary theories.
When good cholesterol goes bad
A new study by Harvard School of Public Health (HSPH) researchers has found that a subclass of high-density lipoprotein (HDL) cholesterol, the so-called good cholesterol, may not protect against coronary heart disease (CHD) and in fact may be harmful.
Cutting calories before cutting in surgery
Strongly restricted diets have already been shown to increase longevity and prolong one’s healthy years, but research highlighted at a Harvard Global Health Institute symposium at the Harvard School of Public Health shows that the benefits of such restriction may extend to more rapid recovery from surgery and an improved ability to fight disease.
A training lifeline for rescuers
The Harvard Humanitarian Initiative has launched a new academy to formalize instruction in international disaster response, with the aim of saving the lives of those threatened by earthquakes, floods, wars, and other catastrophes.
Nicholas Christakis, whose research explores how everything from obesity to smoking to happiness spreads among our social networks, is turning his attention to the past, exploring why and how we became the social animals we are.
From Iraq and back, via 9/11 and Harvard
A Harvard authority on ancient Iraq spent several years studying clay tablets looted from that nation, which had been stored in a World Trade Center building that was destroyed on 9/11. The tablets eventually were retrieved, restored, translated, and returned.
A Harvard engineering class helps find a metric for a computer scheme that tracks gang violence.
The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering and Applied Sciences.
‘Warming hole’ delayed climate change
Climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered that particulate pollution in the late 20th century created a "warming hole" over the eastern United States — that is, a cold patch where the effects of global warming were temporarily obscured.
Steven Raichlen, author of “The Barbecue Bible” and “Planet Barbecue,” discussed on barbecue’s origins among early humans and barbecue customs around the world in a recent Harvard talk.
A new study by Harvard researchers at Brigham and Women’s Hospital (BWH) finds that a high intake of flavonoid-rich berries, such as strawberries and blueberries, over time, can delay memory decline in older women by two and a half years.
