Researchers at the Wyss Institute at Harvard have developed a workflow that could diagnose a patient with Zika within two to three hours. The goal of developing the low-cost, rapid paper-based diagnostic system for strain-specific detection of the Zika virus is its use in the field to screen blood, urine, or saliva samples.

A new study published in the Journal of the American Medical Association shows that income is closely correlated with life expectancy, with the richest Americans living as much as 15 years longer than the poorest — and even the poor living longer in wealthy areas.
Low-income parents face an extra challenge when trying to get their kids to eat healthy: the cost of food wasted if children refuse to eat it.
Levels of a molecular marker in healthy breast tissue can predict a woman’s risk of getting cancer, according to new research from the Harvard Stem Cell Institute.

The Blavatnik Biomedical Accelerator will collaborate with Merck to develop small-molecule therapy for the most common form of acute leukemia.
"Standardized patients" are trained actors who role-play the sort of diagnostic puzzles regularly faced by practicing physicians. They interact with students at the Tosteson Medical Education Center at Harvard Medical School (HMS).
A study by researchers at the Harvard T.H. Chan School of Public Health shows that moderate alcohol consumption can produce a temporary increase in heart attack and stroke risk.
An analysis of data from two long-term epidemiologic studies has found that regular use of aspirin significantly reduces the overall risk of cancer, an effect that primarily reflects a lower risk of colorectal cancer and other tumors of the gastrointestinal tract.
A new study out of Harvard Medical School and the National Running Center at Harvard-affiliated Spaulding Rehabilitation Hospital examined why runners get injured so often.
Children with acute lymphoblastic leukemia who live in high-poverty areas are substantially more likely to suffer early relapse than other patients, according to a new study.
National health insurance is just a first step to solving the divide between America’s well-off healthy and its poorer, sicker people, Harvard analysts say.
America’s top malaria official said that everyday politics presents one of the biggest threats against progress to eliminate the worldwide killer.
Katherine Gregory, a nurse scientist at Brigham and Women’s Hospital, searched for an answer to the mystery of necrotizing enterocolitis (NEC), a sometimes fatal infectious disease of the newborn gut affecting preterm infants.
The Gazette spoke with Michael Charness, chief of staff for the Harvard-affiliated VA Boston Healthcare System, about the CDC’s recommendations to sexually active woman of childbearing age: either use birth control or don’t drink.
A study of plaque production at single-cell level holds promise to help improve Alzheimer’s treatment.
Rett syndrome is a relatively common neurodevelopmental disorder, the second most common cause of intellectual disability in girls after Down syndrome. Building on 2004 findings, Harvard researchers identified a faulty signaling pathway that, when corrected in mice, improves the symptoms of Rett syndrome.
Massachusetts General Hospital researchers are working on a topical treatment that may be available for those with seborrheic keratosis (SK), or liver spots. SKs vary in color from tan to black, can be flat or raised, and range in size from quite small to an inch or more across.
Researchers have found that cancer begins after activation of an oncogene or loss of a tumor suppressor, and involves a change that takes a single cell back to a stem cell state. They believe this model may apply not only to melanoma, but to most if not all cancers.

Koch Institute for Integrative Cancer Research, in collaboration with scientists at the Harvard Stem Cell Institute and several other institutions, have developed an implantable device that in mice shielded insulin-producing beta cells from immune system attack for six months — a substantial proportion of life span.

A multicomponent, microfluidic small airway-on-a-chip model provides new opportunities to study human lung inflammatory disorders such as chronic obstructive pulmonary disease (COPD) and asthma, and to test preclinical drug candidates outside the human body.
Using a visual test that is known to prompt different reactions in autistic and normal brains, Harvard researchers have shown that those differences were associated with a breakdown in the signaling pathway used by one of the brain’s chief inhibitory neurotransmitters.
A study from Brigham and Women’s Hospital offers a new view of how cancer cells extend their reach, co-opting and transforming normal cells through “metastatic hijacking.” The researchers also found that in preclinical models, pharmacological intervention can prevent this from occurring.
