Rebecca DuBois, associate professor of biomolecular engineering at UC Santa Cruz, said the new method her team developed […]

Teamwork, rapid data monitoring needed to improve nation’s heart health

DALLAS, Dec. 3, 2020 — For cardiovascular health to improve in the general population, healthcare systems will need to collect and assess treatment data, establish collaboration between researchers and healthcare professionals, and evolve patient care in real-time based on those data, according to “Achieving Optimal Population Cardiovascular Health Requires an Interdisciplinary Team and a Learning […]

Accuracy of rapid COVID test may be lower than previously suggested

The accuracy of a rapid finger-prick antibody test for SARS-CoV-2, the virus responsible for covid-19 infection, may be considerably lower than previously suggested, finds a study published by The BMJ. The results suggest that if 10% of people given the test had previously been infected, around 1 in 5 positive test results would be incorrect […]

US is a week away from ‘rapid acceleration’ of COVID-19 cases

The U.S. is bracing for a third wave of COVID-19 infections as it moves into the frigid winter months. The country is only about a week away from a “rapid acceleration” in COVID-19 cases, Dr. Scott Gottlieb, former commissioner of the Food and Drug Administration said on CNBC on Monday (Oct. 19).  Coronavirus cases have […]

Disseminating Scientific Results in the Age of Rapid Communication

Earlier this year as the COVID-19 virus spread around the world, countries responded by imposing lockdown measures one by one. Scientists, seeing the subsequent satellite observations, rushed to publish papers about improved air quality, many of which appeared in short order on preprint servers. These preprints, which are often published in tandem with […]

Deep-sea corals reveal secrets of rapid carbon dioxide increase as the last ice age ended

Researchers examined deep-sea coral fossils – species Desmophyllum dianthus – to study carbon sequestration in the Southern Ocean 20,000 to 10,000 years ago. The chemical signatures of nitrogen and carbon in the coral fossils revealed that ocean carbon sequestration decreased as phytoplankton failed to devour macronutrients supplied by upwelling currents in the Southern Ocean and […]
