How DNA outside cells can be targeted to prevent the spread of cancer

Cell-free DNA (cfDNA) is DNA found in trace amounts in blood, which has escaped degradation by enzymes. Scientists from Tokyo University of Science, led by Prof Ryushin Mizuta, have now discovered exactly how cfDNA is generated. They also talk about the applications of DNase1L3—the enzyme mainly responsible for generating cfDNA—as a novel molecule to prevent the spread of tumors. Prof […]

Too much screen time for the kids? Grandparents may also be complicit

Grandparents have long been associated with letting their grandchildren do things their parents would never permit. Candy. Extended bedtime. Too much television. Carefree fun. They like to spoil their grandchildren. A new study by Rutgers and other researchers finds that today’s grandparents are still true to their traditional fun-loving image—allowing their grandchildren, while under their supervision, to spend about half […]

Microvascular disease anywhere in the body may be linked to higher risk of leg amputations

Microvascular disease is independently associated with a higher risk of leg amputation compared to people without the disease, according to new research in the American Heart Association’s journal Circulation. The study, funded by the American Heart Association Strategically Focused Research Network in Vascular Disease and the U.S. Department of Veterans Affairs, examined amputation risk among people with microvascular disease or […]

Could prosthetic limbs one day be controlled by human thought?

For almost two decades, Stanford electrical engineering professor Krishna Shenoy and neuroscientists in his Neural Prosthetics Translational Laboratory have been working on implantable brain sensors that allow them to record and decipher the electrical activity of neurons that control body movement. The long-term goal: to build prosthetics that amputees and those with paralysis can control with their thoughts. Currently, the […]

The flu virus’s ability to mutate may sometimes be its downfall

One of influenza virus’s main weapons is actually a double-edged sword. The virus’s ability to rapidly mutate lets it escape from the immune system’s memory and explains why people can be repeatedly re-infected with flu—unlike measles or polio. But those mutations can also blow the virus’s cover, Howard Hughes Medical Institute Investigator Jesse Bloom and colleagues reported May 8, 2019, […]
