Irene Pepperberg, best known for her work with an African grey parrot named Alex — whose intelligence was estimated as equal to that of a 6-year-old child — recently relocated her lab to Harvard, where she continues to explore the origins of intelligence by working with birds.
Using an imaging technique known as high-speed holographic microscopy, Laurence Wilson, a fellow at Harvard’s Rowland Institute, worked with colleagues to produce detailed 3-D images of malaria sperm — the cells that reproduce inside infected mosquitoes — that shed new light on how the cells move.
Tim Laman, an associate of Harvard’s Museum of Comparative Zoology and an award-winning wildlife photographer, was part of a two-man team that helicoptered into a remote Australian rainforest earlier this year, coming out with three new species: two lizards and a frog.
Harvard researchers have solved the nearly 200-year-old mystery of how Rafflesia, the largest flowering plants in the world, develop.
New research suggests that, despite moonlight’s apparent hunting advantage, large predators such as lions are actually less active on the brightest nights, while many prey animals — despite the risk of being eaten — become more active.
They began with a discovery in zebrafish in 2007, and now researchers at the Harvard Stem Cell Institute (HSCI) have published initial results of a Phase Ib human clinical trial of a therapeutic that could improve the success of blood stem cell transplantation. This marks the first time that HSCI has carried a discovery from the lab bench to the clinic.
Harvard researchers have found that the brain uses two largely independent neural circuits to learn spatial and temporal aspects of complex motor skills.
Many modern chronic diseases result from mismatches between how our bodies evolved to be used and how we use them today, Harvard evolutionary biologist Daniel Lieberman writes in a new book.
Harvard researchers recently developed the most detailed “specificity profile” for Cas9 — a “machine” made of protein and RNA that can be programmed to target specific DNA sequences and to precisely cut, paste, and turn on or turn off genes. Future researchers will use the data when developing genetic tools and therapies.
Students from local high schools spent a chunk of the summer at work in a Harvard lab as part of program co-sponsored by the University’s Life Sciences Education program and the Howard Hughes Medical Institute.

In the high-tech laboratory at the Arnold Arboretum’s Weld Hill Research Building, amid an array of expensive, shiny new equipment, sits a 1931 microtome, a machine whose well-oiled parts keep cranking out slices of tissue just 10 micrometers wide, thin enough for light to penetrate and perfect for making slides to see the internal cellular structure of plants.
In the battle against brain cancer, doctors now have a new weapon: an imaging technology that will make brain surgery dramatically more accurate by allowing surgeons to distinguish between brain tissue and tumors, and at a microscopic level.
An international scientific collaborative led by the Harvard Stem Cell Institute’s Kornelia Polyak has discovered why women who give birth in their early 20s are less likely to develop breast cancer than women who don’t, triggering a search for a way to confer this protective state on all women.
“The Road to Vital Therapy,” part of the Broad’s Institute’s midsummer science lecture series, discussed how researchers are tapping the human genome, hoping to create effective treatments for vexing afflictions.
With classes in plant morphology fading in universities across the country, an Arnold Arboretum short course is seeking to plug the hole, bringing in top botany graduate students and postdoctoral fellows for an intensive, two-week course.
Harvard Stem Cell Institute researchers have identified in the most aggressive forms of cancer a gene known to regulate embryonic stem cell self-renewal, beginning a creative search for a drug that can block its activity.
As part of Professor Gonzalo Giribet’s Biology of Invertebrates class, students make closely observed, highly detailed sketches of animals they study in the lab.
Harvard researchers have demonstrated that the levels of barium in teeth correspond with breast-feeding. Importantly, they said, the barium levels can remain in fossils that are thousands of years old. This provides new opportunities to study breast-feeding behavior among Neanderthals and early humans.
Dan W. Brock of Harvard Medical School on Wednesday delivered the 63rd George W. Gay Lecture in Medical Ethics at the School, focusing on population bioethics.
Led by Joshua Sanes and Jeff Lichtman, a group of Harvard researchers has made a host of technical improvements in the “Brainbow” imaging technique.
