The surprising strength of liquid crystals

Dendrites are the destructive by-products of the cycle of charging and discharging lithium ion batteries. These tiny deposits form between the battery's anode and cathode, building up over time. Inevitably, they diminish battery life. More problematic is their risk of causing the battery to burst into flames. In the quest for safer and longer lasting batteries—especially for electric cars, trucks, and planes—researchers continue to explore methods to suppress the formation of dendrites.

Technology shines the light on ovarian cancer treatments

Scientists estimate that nearly 60% of all cancer patients do not respond effectively to chemotherapy treatments. Even worse—many of those same patients experience toxic and sometimes deadly side effects.

Scientists use gene therapy and a novel light-sensing protein to restore vision in mice

A newly developed light-sensing protein called the MCO1 opsin restores vision in blind mice when attached to retina bipolar cells using gene therapy. The National Eye Institute, part of the National Institutes of Health, provided a Small Business Innovation Research grant to Nanoscope, LLC for development of MCO1. The company is planning a U.S. clinical trial for later this year.

COVID-19 interventions can cut virus infections, severe outcomes, and healthcare needs

Existing heart drugs may help cancer patients respond better to PD(L)1 immunotherapy

Researchers have found that a class of commonly-used heart drugs may also improve patients' responses to anti-cancer immunotherapies called PD(L)1 inhibitors, according to preliminary findings to be presented at the 32th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics, which is taking place online.

Gut bacteria could be responsible for side effect of Parkinson's drug

Bacteria in the small intestine can deaminate levodopa, the main drug that is used to treat Parkinson's disease. Bacterial processing of the unabsorbed fractions of the drug results in a metabolite that reduces gut motility. These findings were described in the journal BMC Biology on 20 October by scientists from the University of Groningen. Since the disease is already associated with constipation, processing of the drug by gut bacteria may worsen gastrointestinal complications.
