How COVID-19 Vaccines and Infections Are Tweaking Our Immunity
Your immune system may be getting smarter every time you encounter COVID-19, a new study suggests. After getting vaccinated and infected, the immune system generates broader defenses against the virus, including against new variants.
In a paper published Jan. 19 in Science Immunology, researchers in South Korea compared immune cells in the lab from people with a variety of vaccine and infection histories throughout the different Omicron waves, which began in late 2021 with BA.1. People who had been vaccinated with the original Pfizer-BioNTech series and then got infected with any Omicron variant showed good levels of me...

‘Lobster eye’ in space promises new look at x-rays
China last week launched an x-ray observatory with an unusual telescope inspired by the structure of lobster eyes to gather new data on gamma ray bursts, supernovae, and stars being swallowed by black holes. The Einstein Probe (illustration above)—a joint project of the Chinese Academy of Sciences, the European Space Agency, and the Max Planck Institute for Extraterrestrial Physics—will also capture x-rays from violent events that generate gravitational waves, such as two neutron stars colliding. The telescope features a survey inst...

Is It Dangerous to Keep Getting COVID-19?
Getting COVID-19 today is much less scary and more common than it was three years ago. By now, many people have had it not just once, but two, three, or even more times. Most of the time, repeat infections aren’t as severe as they were the first time, leading to a sense of complacency about getting COVID-19 over and over.
But reinfections aren’t harmless. As cases continue to rise and more variants arrive on the scene, infectious-disease experts are warning that repeat infections could have cumulative, lasting effects.
