Scientists develop and monitor two approaches to fix blood vessel abnormalities that make tumors difficult to treat: Combining the approaches may be a powerful anti-cancer strategy
Tumors send out signals that impair normal blood flow, which makes them hard to treat with every type of cancer treatment, including radiation and chemo-, targeted and immunotherapy. Impaired blood supply creates an environment low in oxygen levels — hypoxia — that causes the tumors to take on aggressive characteristics and become immuno-suppressed. To address […]
Experts Predict If And When COVID Will Become A Seasonal Illness
The vast majority of respiratory viruses that spread within our population ebb and flow with the seasons. Influenza spikes in the winter months, as do infections caused by respiratory syncytial virus (RSV), adenoviruses and other coronaviruses. Earlier this year, Rochelle Walensky, the Centers for Disease Control and Prevention director, said she expects COVID to also […]
Scientists discover how oxygen loss saps a lithium-ion battery’s voltage: Measuring the process in unprecedented detail gives them clues to how to minimize the problem and protect battery performance
When lithium ions flow in and out of a battery electrode during charging and discharging, a tiny bit of oxygen seeps out and the battery’s voltage — a measure of how much energy it delivers — fades an equally tiny bit. The losses mount over time, and can eventually sap the battery’s energy storage capacity […]
