Millions of Telescopes 4 Light Days From Earth Could Permanently Explore Other Solar Systems

If we send telescopes out to 4 light days we can use the gravity of the sun to amplify the power of telescopes by 100 billion times. Although we can build larger telescopes with higher resolution than exists today near to Earth, the telescopes that are sent out to gravitational lensing regions would resolve much…

KRASG12C-Mutant NSCLC Likely Smoking-Related, Targetable by Brain Metastasis Therapies

NEW YORK (Reuters Health) - KRASG12C-mutant non-small-cell lung cancer (NSCLC) appears to be smoking-related and is likely targetable by inhibitors that can delay or prevent brain metastasis, according to an analysis of real-world outcomes. "Currently, the majority of druggable oncogene-driven NSCLCs occur in non-smokers/light ex-smokers," Dr. Wanyuan Cui of the Peter MacCallum Cancer Centre in…

Proton Pump Inhibitors Tied to COVID-19 Risk

Editor's note: Find the latest COVID-19 news and guidance in Medscape's Coronavirus Resource Center. People who use proton pump inhibitors (PPIs) may be more likely to get COVID-19, researchers say. In light of this finding, physicians should consider which patients truly need these powerful acid-lowering drugs, said Brennan Spiegel, MD, MSHS, professor of medicine and…

Breathed In Dye Enables Intraoperative Visualization of Lung-Tumor Margin

NEW YORK (Reuters Health) - Inhalational indocyanine green (ICG) can be useful for the intraoperative visualization of lung-tumor margin, researchers from South Korea report. Surgical resection with adequate tumor-free margin provides optimal long-term survival in patients with early-stage non-small-cell lung cancer (NSCLC), but defining the tumor margin during surgery can be challenging. Dr. Hyun Koo…
