Cassandra Extavour is the author of a new study that points to a different mechanism as an ancestral process for specifying germ cells.
People spend 46.9 percent of their waking hours thinking about something other than what they’re doing, and this mind wandering typically makes them unhappy, according to research by Harvard psychologists Matthew A. Killingsworth and Daniel T. Gilbert.
New research conducted at Harvard demonstrates sharing behavior in African grey parrots.
A Harvard study shows that although an optimistic outlook may help women live longer, one other possibility is that higher optimism directly impacts our biological systems.
Researchers have created embryonic stem cells without an embryo. This discovery of a novel reprogramming method of adult cells, without introducing external genetic material, could dramatically shift stem cell research.
Remnants of Neanderthal DNA in modern humans are associated with genes affecting type 2 diabetes, Crohn’s disease, lupus, biliary cirrhosis, and smoking behavior. They also concentrate in genes that influence skin and hair characteristics. At the same time, Neanderthal DNA is conspicuously low in regions of the X chromosome and testes-specific genes.
Digital technology and big data will power the next big advance in the business of farming, the head of a “digital agriculture” firm told a Harvard audience.
Behind glass cases, Harvard’s Peabody Museum of Archaeology displays ancient tools, weapons, clothing, and art — enough to jar you back into the past. But the venerable museum offered a jarring moment of another sort in its Geological Lecture Hall last month (March 20). Paleoanthropologist Leslie Aiello delivered a late-afternoon talk on diet, energy, and evolution. It was jolting to see her, slight and matronly, stand before a story-high screen filled with images of rugged early hominids on a savannah, gathered around fallen game.

Hairless, clawless, and largely weaponless, ancient humans used the unlikely combination of sweatiness and relentlessness to gain the upper hand over their faster, stronger, generally more dangerous animal prey, Harvard Anthropology Professor Daniel Lieberman said Thursday (April 12).
Relaxation-response techniques, such as meditation, yoga, and prayer, could reduce the need for health care services by 43 percent, according to a Harvard-affiliated Massachusetts General Hospital study that looked at participants in a relaxation-response-focused training program.
While recent federal guidelines enhanced the nutritional quality of school lunches, there are no standards regarding lunch period length. Many students have lunch periods that are 20 minutes or less, which can be an insufficient amount of time to eat, according to a new study from the Harvard T.H. Chan School of Public Health.
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 ...
New research challenges the notion that the small pelvic bones found in whales are evolutionary vestiges.
Inspired by his experience in the 2005 New York Marathon, an M.D./Ph.D. student has taken a rigorous approach to calculating just how much carbohydrate a runner needs to fuel himself or herself through 26.2 miles, and what pace that runner can reasonably expect to sustain.
A philosophy professor’s summer of diving in Sydney Harbour has gotten him thinking about what octopus intelligence might mean.
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.
Assistant professor Arkhat Abzhanov looks to birds’ relatives by way of dinosaurs — alligators — for clues to their evolution.
Harvard’s Origins of Life Initiative has grown along with the rise in interest in how life first arose on Earth and whether it exists on other planets.
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 Savage at the Harvard Medical School and Geoffrey West of the Santa Fe Institute in New Mexico believe they have found a good answer.
In a first-of-its-kind study, Harvard researchers have shown that cooked meat provides more energy than raw meat, a finding that challenges the current food labeling system and suggests humans are evolutionarily adapted to take advantage of the benefits of cooking.
An Origins of Life researcher has created a chemical system that mimics early cell behavior.
Experiments conducted in a Harvard lab reveal that, while sharks’ sandpaperlike skin does allow the animals to swim faster and more efficiently, the structure of some high-tech swimsuits has no effect when it comes to reducing drag as swimmers move through the water.
Harvard Business School social psychologist Amy Cuddy explains how tapping into our inner strength can help us make the most of life’s big challenges.
Researchers have found that due to warming temperatures, phytoplankton can now grow under Arctic sea ice, dramatically changing the ecology.
After 26 years of workdays spent watching bacteria multiply, Richard Lenski has learned that evolution doesn’t always occur in steps so slow and steady that change can’t be observed.
The Wyss Institute and Harvard Medical School’s Personal Genome Project are collaborating with Lumos Labs, the makers of Lumosity, to investigate the relationship between genetics and memory, attention, and reaction speed.
Researchers at Harvard have shown that Nodal and Lefty — two proteins linked to the regulation of asymmetry in vertebrates and the development of precursor cells for internal organs — fit a mathematical model first described by Alan Turing six decades ago.
The positive effects of mindfulness meditation on pain and working memory may result from an improved ability to regulate a crucial brain wave called the alpha rhythm. This rhythm is thought to "turn down the volume" on distracting information, which suggests that a key value of meditation may be helping the brain deal with an often overstimulating world.
A Graduate School of Education alumna brings her family history into the dance studio as she teaches children with disabilities the art of movement and the rewards they can reap.
New research not only sheds new light on how hearing works, but could help clarify how it deteriorates over time.
Evidence is mounting that Earth’s water arrived during formation, aboard meteorites and small bodies called “planetesimals.”
Researchers in the Department of Neurobiology at Harvard Medical School have developed a technique for unraveling these masses. Through a combination of microscopy platforms, researchers can crawl through the individual connections composing a neural network, much as Google crawls web links.
In a new paper, Harvard researchers show that changes in coat color in mice are the result not of a single mutation, but of many mutations, all in a single gene. The results start to answer one of the fundamental questions about evolution: Does it proceed by huge leaps — single mutations that result in dramatic changes in an organism — or is it the result of many smaller changes over time?
Research led by a Harvard professor describes in detail how termite mounds are ventilated.
Biologists at Harvard University have identified the ancient fossilized remains of a pollen-bearing bee as the first hint of orchids in the fossil record, a find they say suggests orchids are old enough to have coexisted with dinosaurs.
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.
State wildlife biologists installed a peregrine falcon nesting platform high on Memorial Hall’s tower.
Researchers discover how fungi developed an aerodynamic way to reduce drag on their spores so as to spread them as high and as far as possible.
Researchers at Harvard University say America’s obesity epidemic won’t plateau until at least 42 percent of adults are obese, an estimate derived by applying mathematical modeling to 40 years of Framingham Heart Study data.
A sophisticated examination of teeth from 11 Neanderthal and early human fossils suggests that modern humans' slow development and long childhood are recent and unique to our own species, and may have given early humans an evolutionary advantage over Neanderthals.
Harvard Stem Cell Institute scientists collaborating with researchers at the University of Pennsylvania have developed a “genome-editing” approach for permanently reducing cholesterol levels in mice through a single injection, a development with the potential to reduce the risk of heart attacks in humans by 40 to 90 percent.
A team of researchers led by Harvard geneticist George Church at the Wyss Institute for Biologically Inspired Engineering and Harvard Medical School has made big strides toward a future in which the predominant chemical factories of the world are colonies of genetically engineered bacteria.
A new drug compound developed by researchers at Massachusetts General Hospital and the Harvard Stem Cell Institute to treat acute myeloid leukemia is gentle enough to use with patients too frail to endure chemotherapy.
A team of researchers at Harvard University and the California Institute of Technology has turned inanimate silicon and living cardiac muscle cells into a freely swimming “jellyfish.”
Scientists have shown that to interrupt the development of pigment cells that form their stripes, African striped mice and chipmunks both use a gene that until now had been associated primarily with cranio-facial development.
