Researchers at Harvard-affiliated McLean Hospital are reporting that xenon gas, used in humans for anesthesia and diagnostic imaging, has the potential to be a treatment for post-traumatic stress disorder (PTSD) and other memory-related disorders
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.
The protective gear needed to get Sierra Leone’s health clinics reopened, coupled with public education about the Ebola epidemic, are the greatest areas of need, according to a Harvard Fulbright Fellow and physician from Sierra Leone.
Though the threat to the U.S. population from the Ebola outbreak in West Africa is low, the need in epidemic countries is great, says Michael VanRooyen, director of the Harvard Humanitarian Initiative.
In pre-clinical studies conducted by the researchers, a one-time, local injection of the hydrogel-drug combo prevented graft rejection for more than 100 days. This compared with 35.5 days for recipients receiving only tacrolimus, and 11 days for recipients without treatment or only receiving hydrogel.
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.
Studies begun by Harvard Stem Cell Institute scientists eight years ago have led to a report that may be a major step in developing treatments for amyotrophic lateral sclerosis, or Lou Gehrig’s disease.
Harvard researchers have joined with counterparts in the U.S. and Botswana governments to conduct a major evaluation of AIDS treatment targeted specifically to reduce infectivity.
Children born with so-called “bubble boy” disease have the best chance of survival if they undergo a hematopoietic stem cell transplant as soon after birth as possible, according to a detailed analysis of 10 years of outcome data by researchers at the Harvard-affiliated Dana-Farber/Boston Children’s Cancer and Blood Disorders Center.
A new study shows that boosting inhibitory neurotransmission early in brain development can help reverse deficits in inhibitory circuit maturation that are associated with autism.
In a study at Harvard-affiliated McLean Hospital, individuals with major depressive disorder or bipolar disorder who received low-field magnetic stimulation (LFMS) showed immediate and substantial mood improvement.
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.
To David Altshuler, the recent discovery of a genetic mutation that protects against type 2 diabetes offers hope in fighting more than just diabetes. It also illustrates how using the…
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.
Philanthropist Ted Stanley announced plans to donate $650 million to the Broad Institute of Harvard and MIT to foster research into psychiatric diseases, whose biological causes, long a mystery, scientists have begun to tease out in recent years.
Harvard-affiliated researchers joined an international team to identify more than 100 locations in the human genome associated with the risk of developing schizophrenia in what is the largest genomic study published on any psychiatric disorder to date.
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.
New research raises the prospect of more effective treatments for cachexia, a profound wasting of fat and muscle that occurs in about half of all cancer patients, increasing their risk of death. Harvard Professor Bruce Spiegelman demonstrated that symptoms of cachexia in mice improved when given an antibody that blocked the effects of a protein secreted by the tumor cells.
Vasectomy is associated with a small increased risk of prostate cancer, and a stronger risk for advanced or lethal prostate cancer, according to a new study from Harvard School of Public Health.
A new study found that two-child families present five times more risk of sibling obesity than single-child homes with an obese parent, which doubles the risk. Obesity risk is even stronger among same-gender siblings.
Harvard-affiliated researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule that acts as a marker for hard-to-find limbal stem cells.
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.
Will Lautzenheiser, a former Boston University film professor who lost his arms and legs from an infection, has been cleared by the Institutional Review Board at the Harvard-affiliated Brigham and Women’s Hospital for a double arm transplant, a complex procedure requiring 12 to 16 hours of work by a team of surgeons.
A team of researchers led by David J. Mooney, Robert P. Pinkas Family Professor of Bioengineering at the Harvard School of Engineering and Applied Sciences, has identified a possible mechanism by which normal cells turn malignant in mammary epithelial tissues, those frequently involved in breast cancer.
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 Harvard researchers has demonstrated that a shared developmental mechanism in songbirds is responsible for generating tremendous variability in their beaks, and is also a control on what kind variation can be produced.
