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.

A study from Harvard Medical School provides the first comprehensive description of how cytomegalovirus, or CMV, hijacks human cells and suggests entirely new ways to combat the infection.

A natural hormone that is increased by physical exercise and by exposure to cold improves blood sugar control, suppresses inflammation, and burns fat to mold leaner bodies in mice, report scientists at the Harvard-affiliated Dana-Farber Cancer Institute.

Divinity School graduate Shelley Brown is combining her love for science and religion to help stitch together two fields that rarely seem to meet.

The Harvard Stem Cell Institute is now 10 years old. What began as an idea embracing cross-disciplinary research quickly became a generator of scientific discoveries.

With a master’s from the School of Public Health, physician Darrell Gray hopes to use telecommunications to extend care to endangered groups in underserved neighborhoods.

Panelists at HSPH examined the trend toward delayed parenting identified in a recent government report.

Harvard scientists have discovered a compound that inhibits insulin-degrading enzyme from breaking down insulin in the body.

Will Clerx ’14 studied how going without sleep for long periods affects undergraduates.

It could be that the key to being a better parent is all in your head, Harvard researchers say.

Harvard scientists have merged stem cell and “organ-on-a-chip” technologies to grow, for the first time, functioning human heart tissue carrying an inherited cardiovascular disease. The research appears to be a big step forward for personalized medicine, because it is working proof that a chunk of tissue containing a patient’s specific genetic disorder can be replicated in the laboratory.
