A conservation group has tracked a migration for the ages, in which a male bar-tailed godwit flew from Alaska to New Zealand without taking a single break.
When you title a research paper “In Search for a Planet Better than Earth,” you’re not messing around. Earth, the only place we know for sure hosts life, sets a high bar for all other planets.
Scientists in Nevada are the latest to report a likely case of reinfection from the coronavirus that causes covid-19, with genetic evidence backing up their claim. While it remains to be seen whether reinfection will be a common phenomenon, this newest case suggests that a second infection can cause more severe illness than the first, even in young and seemingly healthy people.

On August 16, a car-sized asteroid came to within 1,830 miles (2,950 kilometers) of our planet, making it the closest known non-impacting asteroid on record. Continue reading A Car-Sized Asteroid Just Got Remarkably Close to Hitting Earth
Indigenous South Americans reached islands in the South Pacific some 300 years before Christopher Columbus landed in the Americas, according to new genetic evidence. Continue reading Native Americans Voyaged to Polynesia Long Before Europeans Reached the Americas, DNA Study Shows
Scientists in the UK think they may have found a cheap, low-tech way to help fight age-related loss of vision. In a small clinical trial, people over 40 who were told to stare into a deep red light for three minutes a day had noticeable improvements to their sight. They reported being able to see better in the dark and to better distinguish colors.
Astronomers are having an easier time finding fast radio bursts as of late, and that now includes the first regular pattern for those bursts. A research team from MIT and elsewhere has discovered that something 500 million light-years away is routinely producing four days of seemingly random but frantic bursts, followed by 12 days of silence — something that happened consistently for 500 days of study.
