Now, a team led by researchers from Harvard Medical School, the Broad Institute of MIT and Harvard, Massachusetts Eye and Ear, Harvard University and Howard Hughes Medical Institute have […]

Gene therapy holds promise for treating a variety of diseases, including some inherited blinding conditions. But for a gene therapy to be effective, one must know the precise gene responsible for a given individual’s disorder and develop a tailored treatment. For diseases that may be caused by mutations in many […]

Oregon State University scientists have developed a nanomedicine platform for cancer that can help doctors know which tissue to cut out as well as kill any malignant cells that can’t be surgically removed. The platform allows for greater precision and thoroughness in cancer treatment. Here’s how it works: Nanoparticles tightly […]

New research has drawn a link between changes in the brain’s anatomy and biomarkers that are known to appear at the earliest stages of Alzheimer’s disease (AD), findings that could one day provide a sensitive but non-invasive test for AD before cognitive symptoms appear. Scientists have known for some time […]

A device attached to a patient’s scalp that delivers a continuous dose of low-intensity electric fields improves survival and slows the growth of a deadly brain tumor, according to a new clinical trial led by a Northwestern Medicine scientist and published in the journal JAMA. The new treatment for glioblastoma uses […]

Scientists have found a new way to explain the hearing loss caused by cisplatin, a powerful drug used to treat many forms of cancer. Using a highly sensitive technique to measure and map cisplatin in mouse and human inner ear tissues, researchers found that forms of cisplatin build up in […]

UC San Francisco physician-scientists have developed a test that can predict how patients with juvenile myelomonocytic leukemia (JMML) will respond to treatment, and may also be able to identify patients who are likely to recover spontaneously with little to no treatment. The researchers are currently optimizing the test for more […]

Immune cells are normally associated with fighting infection, but in a new study scientists have discovered how they also help the nervous system clear debris, potentially clearing the way for nerve regeneration after injury. In a study published in the Journal of Neuroscience, researchers from Case Western Reserve University School of […]

Treatment for the most deadly form of skin cancer could be more effective if combined with a well-known drug for rheumatoid arthritis, new research has shown. The study, by scientists at the University of East Anglia (UEA), found that in mice, using the two treatments together almost completely stopped the […]

New findings by scientists at the University of Southampton could help to predict how people with the most common form of leukaemia will respond to chemotherapy. The findings will help doctors decide which type of treatment to give patients. The researchers, who were funded by the blood cancer research charity […]

Rapidly dividing, yet aberrant stem cells are a major source of cancer. But a new study suggests that mature cells also play a key role in initiating cancer — a finding that could upend the way scientists think about the origins of the disease. Researchers at Washington University School of […]

Research at The City College of New York shows that cancer imaging can be simplified by a photonic process utilizing molecules derived from horse chestnuts. The study with potential to better detect the presence of cancer is led by George John, professor in City College’s Division of Science, in collaboration with Jan Grimm, a […]

Researchers at the University of Tokyo and their collaborators have identified recurrent fusion genes—new genes formed from the combination of two or more separate genes that appear in more than one sample of a disease taken from different patients—tied to a form of pediatric T-cell acute lymphoblastic leukemia (T-ALL), a […]

FLIM, FRET and FLIRR don’t mean anything to most people, but to scientists studying the inner workings of cells, these high-resolution imaging techniques are essential tools for gaining insights to cellular behavior at the molecular level. Cells communicate with each other and multiply, and how they operate from within is […]

he evidence is clear: Cervical cancer is best treated with brachytherapy, a form of radiation therapy. Yet the use of this potentially life-saving treatment has been declining, and a new study from the University of Virginia School of Medicine may explain why. UVA researchers have determined that offering brachytherapy for […]

‘A Nobel Prize for the biological clock has long been overdue,’ says Dorothee Staiger. What is so remarkable is that the prize has been granted to basic research – that is, to studies on fundamental concepts in nature. Whereas the American colleagues have been analysing the biological clock in animals, […]

The efficacy of many FDA-approved cancer drug combinations is not due to synergistic interactions between drugs, but rather to a form of “bet hedging,” according to a new study published by Harvard Medical School researchers in Cell. Reanalyzing data from 15 clinical trials, the researchers show that independent action—in which drugs […]

  Scientists have identified differences in a group of genes they say might help explain why some people need a lot more sleep — and others less — than most.  The study, conducted using fruit fly populations bred to model natural variations in human sleep patterns, provides new clues to […]
