It’s always fun to have a ladybug land on your arm while outside — but these days, it’s more and more likely that any ladybugs landing on you or the plants in your garden are not native to North America. Over the past three decades, several ladybug species native to North America have all but disappeared from the landscape.

As The Matrix’s Neo might say: Whoa.
While that’s still the stuff of fantasy, there have been serious attempts to create artificial wombs dating back to the 1960s. Most fell far short of t ...read more
Connected devices make our lives easier — and more vulnerable. We need white hats more than ever.
One winter morning in 2015, as he left for work from his home in Silver Spring, Md., Jonathan Margulies pushed the button on his remote to close his garage door. Nothing happened. He tried again.

The decrease in out-of-hospital cardiac arrests researchers observed in a pilot study of the Portland, Ore., area after the Affordable Care Act went into effect.

A scientist creates a crowdfunding platform for other researchers.
Like many undergrads in science fields, Cindy Wu was intrigued by an academic career in research. After the biology major graduated in 2011, she worked as a research assistant at the University of Washington in Seattle, her alma mater. While there, she wanted to repurpose a treatment for anthrax to help clear up staph infections, but wasn’t sure how to get money for her idea. When she approached her adviser about it, W ...read more
