A new decision framework developed by MIT researchers shows that, when patients with aggressive T-cell lymphoma relapse within 12 months of initial therapy, their chances for survival decline dramatically. This prognostic marker could help clinicians identify high-risk patients earlier.
On Saturday December 6, 2025 Alaska was rocked by a 7.0 magnitude quake. On average, about 55 earthquakes strike daily, according to the United States Geological Survey (USGS), totaling some 20,000 annually worldwide with 15 hitting within the magnitude 7.0 range and one reaching 8.0 or over. Earthquakes result in fatalities, damaged infrastructure, economic disruptions and can create lasting psychological trauma for individuals affected by them. They are also becoming more costly, in part because more people now live in the earthquake-prone areas, with damage reaching $14.7 billion per year in the US alone. There's no way to predict when earthquakes may hit yet, but a new paper may bring us a step closer to doing so.
Interactions among viruses can help them succeed inside their hosts or impart vulnerabilities that make them easier to treat. Scientists are learning the ways viruses mingle inside the cells they infect, as well as the consequences of their socializing. Although it is debatable whether viruses are living things, they do compete, cooperate and share genome materials that can sometimes alter their responses to antiviral drugs, result in new variants or play a role in virus evolution. A paper today in Nature Ecology & Evolution by UW Medicine scientists looks at the evolution of poliovirus resistance to a promising experimental antiviral drug, pocapavir. While it seemed counterintuitive, the researchers demonstrated that lowering the potency of pocapavir could improve the situation by enhancing the survival of enough susceptible viruses to continue sensitizing the resistant ones.
