Warnings about misinformation are now regularly posted on Twitter, Facebook, and other social media platforms, but not all of these cautions are created equal. New research from Rensselaer Polytechnic Institute shows that artificial intelligence can help form accurate news assessments -- but only when a news story is first emerging.

Researchers have developed a new integrated genetic/epigenetic DNA-sequencing protocol known as MultiMMR that can identify the presence and cause of mismatch repair (MMR) deficiency in a single test from a small sample of DNA in colon, endometrial, and other cancers. This alternative to complex, multi-step testing workflows can also determine causes of MMR deficiency often missed by current clinical tests.

Researchers have developed a predictive theory for tumor growth that approaches the subject from a new point of view. Rather than focusing on the biological mechanisms of cellular growth, the researchers instead use thermodynamics and the physical space the tumor is expanding into to predict its evolution from a single cell to a complex cancerous mass.

Researchers describe the effects of antibiotics on membrane vesicles, demonstrating that such drugs actively modify the properties of vesicle transport. Under the influence of antibiotics, MVs were produced and released by bacteria in greater abundance and traveled faster and further from their origin. The work sheds new light on these important information-carrying entities, implicated in many cellular communication processes, including antibiotic resistance.

A team of researchers has found a mechanism that protects a fetus from harm when the mother's innate immune system responds to a viral infection. Inflammation that would harm the fetus is dampened by a cell-surface estrogen receptor called GPER1 that is especially abundant in the placenta and fetal tissues.

A new global, mathematical modeling study shows that in most cases prioritizing older adults for COVID-19 vaccines saves the most lives. It also found that, in some cases, more lives could be saved and infections prevented if those who've already tested positive step to the back of the line.

Under FDA emergency-use authorization, doctors successfully resolved COVID-19 in a seriously ill, immunodeficient woman using a very high-neutralizing antibody-titer convalescent plasma from a recovered COVID-19 patient. However, further study suggested that use of convalescent plasma may not be warranted in many cases, for two reasons: 1) titer levels are too low in many convalescent plasmas, and 2) there are high endogenous neutralizing antibody titers already present in COVID-19 patients prior to infusion.
