Researchers Built an "Online Lie Detector." Honestly, That Could Be a Problem

Not only does the study not necessarily serve as the basis of any kind of reliable truth-telling algorithm, but it makes potentially dangerous claims: A text-based "online polygraph" that's faulty, they warn, could have far worse social and ethical implications if adopted than leaving those determinations up to human judgment.

For example, multiple signals of the same gravitational wave allow you to pinpoint more precisely where it originated, much like GPS uses multiple satellites to locate your position, says Jo van den Brand of VU Amsterdam, who leads an Italy-based gravitational wave observatory known as Virgo.

Twitter Still Can't Keep Up With Its Flood of Junk Accounts, Study Finds

Flooding the Zone In an 16-month study of 1.5 billion tweets, Zubair Shafiq, a computer science professor at the University of Iowa, and his graduate student Shehroze Farooqi, identified more than 167,000 apps using Twitter's API to automate bot accounts that spread tens of millions of tweets pushing spam, links to malware, and astroturfing campaigns.

Dark Matter Hunters Are Looking Inside Rocks for New Clues

Tiny Taps Around five years ago, Freese started tossing around ideas for new detector types with Andrzej Drukier , a physicist now at Stockholm University who began his career studying dark matter detection before pivoting to biophysics.

Dark Matter Hunters Pivot After Years of Failed Searches

Even DAMA’s results have been called into question: In December, Maruyama’s team published that their detector, a South-Korea based DAMA replica made of some 200 pounds of sodium iodide crystal, failed to reproduce its Italian predecessor’s results.These experiments are all designed to search for a specific dark matter candidate, a theorized class of particles known as Weakly Interacting Massive Particles, or WIMPs, that should be about a million times heavier than an electron.

“Finding those individuals is currently very difficult,” says Logan.In this study, dogs were trained to sniff out malaria through the scent of the disease in samples of socks worn by infected children.Medical Detection DogsAn entomologist by training, Logan spent the early years of his career trying to understand why some people are more attractive to mosquitoes than others.

"When I saw the first land images of inland water bodies, I was amazed at their quality," said Chris Ruf, CYGNSS's principal investigator at the University of Michigan in Ann Arbor. The CYGNSS satellites measure wind speed by determining how choppy the water is from a microwave signal bounced off the ocean surface.
