In 2014, two years after her Nobel Prize-winning invention of CRISPR-Cas9 genome editing, Jennifer Doudna thought the technology was mature enough to tackle a cure for a devastating hereditary disorder, sickle cell disease, that afflicts millions of people around the world, most of them of African descent. Some 100,000 Black […]

A year ago, when the COVID-19 lockdown began, Dr. Rachel Issaka expected that colonoscopies would decline. She was surprised by how much. In the first two months, in-clinic colon cancer screenings fell by 90%.  “I was shocked,” said Issaka, a UW Medicine gastroenterologist and researcher with the Fred Hutchinson Cancer Research Center. There […]

When cancer invades the brain, normal salt levels are quickly thrown off-kilter, but detecting this change in patients has been difficult. A team of Yale researchers has developed a non-invasive way to observe these changes in close detail at the early stages of cancer growth. This method, developed in the […]

Earlier studies have shown that supplementary vitamin D seems to provide a certain degree of protection against respiratory infections. A new study involving researchers from Karolinska Institutet has now made the most comprehensive synthesis to date of this connection. The study, which is published in the journal Lancet Diabetes & […]

When variants of SARS-CoV-2 (the virus that causes COVID-19) emerged in late 2020, concern arose that they might elude protective immune responses generated by prior infection or vaccination, potentially making re-infection more likely or vaccination less effective. To investigate this possibility, researchers from the National Institute of Allergy and Infectious […]

A new study shows that in the time after first trying cannabis or first misusing prescription drugs, the percentages of young people who develop the corresponding substance use disorder are higher among adolescents (ages 12-17) than young adults (ages 18-25). In addition, 30% of young adults develop a heroin use […]

In a landmark study, a team led by researchers at the Perelman School of Medicine at the University of Pennsylvania has discovered—and filmed—the molecular details of how a cell, just before it divides in two, shuffles important internal components called mitochondria to distribute them evenly to its two daughter cells.
