Harvard geneticist George Church discussed the future of genetic engineering, including possible technological applications allowing new treatment techniques. He saw the potential to improve human health, revolutionize pest management, and perhaps even bring back the mammoth and other extinct species.
A small study from a group of Harvard-affiliated researchers at Massachusetts General Hospital investigates differences in how important brain structures are activated when women view images of their own children and their dogs.
New research shows that trade is one of the major drivers of biodiversity among lizard species in the Caribbean islands.
New research by Harvard scientists shows how hummingbirds evolved a novel mechanism of taste.
Six Harvard Medical School (HMS) researchers were among the recipients of the 2014 António Champalimaud Vision Award, the highest distinction in ...
Using simple hydrodynamics, a team of Harvard researchers was able to show that a handful of principles govern how virtually every animal — from the tiniest fish to birds to the largest whales — propel themselves through the water.
A new study shows that chimps engage in violent and sometimes even lethal behavior regardless of human effects on local ecology.
Researchers uncovered a variety of features in the genomes of five species of African cichlid fish that enabled them to thrive in new habitats and ecological niches. The findings from these “natural mutants” shed new light on the molecular process of evolution in all vertebrate species.
Research led by a Harvard biologist demonstrated a method for measuring the strength of selection in favor of reproductive isolation.
In the Hunnewell Building is the Arnold Arboretum Horticultural Library, whose books, papers, and photographs ― stored near living collections of many of the same plants they describe ― draw scholars from around the world.

A new study conducted by Harvard scientists shows that in deer mice, a species known to be highly promiscuous, sperm clump together to swim in a more linear fashion, increasing their chances of fertilization.
A new study sheds light on the extent to which animals can make distinctions among scents.
The Gazette spoke with Arboretum officials about the recent arrival of the emerald ash borer.
Using genetic tools to implant genes that produce fluorescent proteins in the DNA of transparent C. elegans worms, Harvard scientists have been able to shed light on neuron-specific “alternative splicing,” a process that allows a single gene to produce many different proteins.
Bauer Fellow Rachel Dutton has identified three general types of microbial communities that live on cheese, opening the door to using each as a “model” community for the study of whether and how various microbes and fungi compete or cooperate as they form communities, as well as what molecules and mechanisms are involved in the process.
The largest-ever phylogenetic spider study shows that, contrary to popular opinion, the two groups of spiders that weave orb-shaped webs do not share a single origin.
A new technique for observing neural activity will allow scientists to stimulate neurons and observe their firing pattern in real time. Tracing those neural pathways can help researchers answer questions about how neural signals propagate, and could one day allow doctors to design individualized treatments for a host of disorders.
A new theoretical framework outlined by a Harvard scientist could help solve the mystery of how bacterial cells coordinate processes that are critical to cellular division, such as DNA replication, and how bacteria know when to divide.
A team at Harvard Stem Cell Institute recently found that transplanting mesenchymal stem cells along with blood-vessel-forming cells naturally found in circulation improves results. This co-transplantation keeps the mesenchymal stem cells alive longer in mice after engraftment, up to a few weeks compared with hours without co-transplantation.
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.
