The dramatic diversity of columbine flowers can be explained by a simple change in cell shape. To match the pollinators’ probing tongues, the flowers’ cells in floral spurs elongate, driving rapid speciation.
Researchers at Harvard Medical School and Children’s Hospital Boston have retraced the evolution of an unusual bacterial infection as it spread among cystic fibrosis patients by sequencing scores of samples collected during the outbreak, since contained.
Researchers from Harvard-affiliated Brigham and Women’s Hospital evaluated whether eliminating co-payments for specific medications following a heart attack would increase adherence and improve outcomes in patients.
A major international study has identified a novel gene mutation that appears to increase the risk of both inherited and sporadic cases of malignant melanoma, the most deadly form of skin cancer.
Researchers have decoded the genome of an unlikely ally in the fight against cancer and aging, the naked mole rat, to find clues on why it resists the disease and lives 10 times as long as ordinary mice.
Individuals addicted to prescription painkillers are more likely to succeed in treatment with the aid of the medication buprenorphine-naloxone (Suboxone), report McLean Hospital and Harvard Medical School researchers.
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.
A new study led by a scientific team at Beth Israel Deaconess Medical Center and Harvard Medical School has uncovered another key mechanism that cancer cells use as part of their survival strategy — and once again it seems that they are using an enzyme called PKM2 to their advantage.
Using genetic tools, researchers at Harvard and collaborating institutions have completed the most comprehensive evolutionary tree ever produced for mollusks. Described in the Nov. 2 issue of Nature, the work also serves as a proof-of-concept, demonstrating the power of genomic techniques to answer difficult evolutionary questions.
In a discovery that might eventually lead to new biomedical treatments for disease, researchers from Harvard’s Department of Molecular and Cellular Biology have identified two types of RNA that are able to move between cells as part of a process called RNA-interference (RNAi).
Report reveals that readily available and affordable cancer prevention, treatment, and pain relief interventions could decrease deaths and improve the lives of millions in developing countries.
Researchers have built a map that shows how thousands of proteins in a fruit fly cell communicate with each other. This is the largest and most detailed protein interaction map of a multicellular organism, demonstrating how approximately one-third of the proteins cooperate to keep life going.
Harvard researchers have cloned stem cells from the airways of the human lung and have shown that these cells can form into the lung’s alveoli air sac tissue. Mouse models suggest that these same stem cells are deployed to regenerate lung tissue during acute infection, such as during influenza.
Exposure in the womb to bisphenol A (BPA) — a chemical used to make plastic containers and other consumer goods — is associated with behavior and emotional problems in young girls, according to a study led by researchers at Harvard School of Public Health.
Panelists at a Harvard School of Public Health Forum Oct. 20 said that changing agriculture policy may be necessary to reform the nation’s diet, which is blamed for worsening current epidemics of obesity and diabetes.
Harvard specialists discussed research on memory development during a seminar aimed at helping military families talk to their children about deployments and homecomings.
Scientists at Harvard-afilliated Dana-Farber Cancer Institute and the Broad Institute have found strikingly high levels of a bacterium in colorectal cancers, a sign that it might contribute to the disease and potentially be a key to diagnosing, preventing, and treating it.
Taking aim at the alarming slowdown in the development of new and lifesaving drugs, Harvard Medical School is launching the Initiative in Systems Pharmacology, a comprehensive strategy to transform drug discovery by convening biologists, chemists, pharmacologists, physicists, computer scientists, and clinicians to explore together how drugs work in complex systems.
Fourteen Harvard surgeons, supported by 36 anesthesiologists, radiologists, nurses, and other medical personnel at Harvard-affiliated Brigham and Women’s Hospital, worked for 12 hours to give a new pair of hands to a 65-year-old Revere man who lost both arms below the elbows and both legs below the knees as a result of a septic infection in 2002.
Research into the effects of last year’s massive BP oil spill in the Gulf of Mexico highlights the flexibility of the community of microbes living in the ocean’s depths.
Flipping a single molecular switch can reverse illness in an animal model of sickle cell disease, according to a study by Harvard researchers at Children’s Hospital Boston and Dana-Farber Cancer Institute.
A professor studies how the structure of large proteins influences how we feel heat, examining how the proteins behave and interact with molecules around them.
The Wyss Institute for Biologically Inspired Engineering at Harvard has been awarded a $12.3 million, four-year grant from the Defense Advanced Research Projects Agency to develop a treatment for sepsis, a commonly fatal bloodstream infection.
Two decades after the Americans with Disabilities Act went into effect, people with disabilities continue to face difficulties meeting major social needs, including obtaining appropriate access to health care facilities and services.
Five years after first gaining institutional permission to attempt to produce stem cell lines via somatic cell nuclear transfer (SCNT), two Harvard researchers and a former Harvard postdoctoral fellow have closed the loop with a flurry of new studies and a commentary in several leading journals.
In a new research paper published in the Proceedings of the National Academy of Sciences Early Edition online, Harvard-affiliated researchers identify a transcriptional biomarker that may assist in the monitoring of Huntington’s disease activity and in the evaluation of new medications.
With the advent of new techniques and anti-rejection drugs, organ transplantation stands on the threshold of a new era, where once-radical surgeries such as face transplants will seem routine, says Bohdan Pomahac, the Brigham and Women’s Hospital surgeon and Harvard Medical School professor who led recent face transplant surgeries.
