COVID-19 antibodies present in patients four months after recovery: study

In previous studies, antibody levels dropped sharply within a few months after COVID-19, raising questions about the duration of immunity that infection may provide. The new finding may have implications for reinfection risks and vaccine durability, said Kari Stefansson, chief executive of deCode Genetics, which conducted the study. To get a sense of how many people in Iceland had been infected...

Large antibody study offers hope for virus vaccine efforts

Tuesday’s report, from tests on more than 30,000 people in Iceland, is the most extensive work yet on the immune system’s response to the virus and is good news for efforts to develop vaccines. If a vaccine can spur production of long-lasting antibodies like natural infection does, it gives hope that “immunity to this unpredictable and highly contagious virus may not be fleeting,”...

UN agency laments summer's 'deep wound' to Earth's ice cover

The United Nations weather agency says this summer will go down for leaving a “deep wound” in the cryosphere -- the planet’s frozen parts -- amid a heat wave in the Arctic, shrinking sea ice and the collapse of a leading Canadian ice shelf. The World Meteorological Organization said Tuesday that temperatures in the Arctic are rising twice as fast as the global average, provoking what...

Can I use a face shield instead of a mask?

Face shields have the added benefit of protecting your eyes and discouraging you from touching your face by acting as a physical barrier, says Christopher Sulmonte, project administrator of the biocontainment unit at Johns Hopkins Hospital. Meanwhile, the available research so far indicates that the best face shields for preventing viral spread are hooded or wrap around the sides and bottom of...

Artists create paintings designed to be tempered in space on Blue Origin’s rocket

Uplift Aerospace and Amazon CEO Jeff Bezos' Blue Origin rocket venture plan to put paintings where virtually no art has gone before: on the side of a rocket ship. The "canvases" for these works are exterior panels that will be mounted on Blue Origin's suborbital New Shepard spaceship, sent to the space frontier during an uncrewed test flight, then returned to Earth for delivery...

AstraZeneca's COVID-19 vaccine candidate begins late-stage U.S. study

Trial participants will receive either two doses of the experimental vaccine, dubbed AZD1222, four weeks apart, or a placebo, the company said. The trial is being conducted under U.S. government's Operation Warp Speed program, which aims to accelerate development, manufacturing and distribution of vaccines and treatments for COVID-19. U.S. President Donald Trump has said a vaccine for the novel...
