How Bedbugs Became Resistant To Today S Insecticides Killing Bedbugs

Media Platforms Design TeamUntil about a decade ago, most people in the United States only knew about bedbugs through the seemingly dated phrase “Sleep tight, don’t let the bedbugs bite.” But the bloodsucking parasites, which were largely eradicated by the mid-20th century, have roared back in all 50 states, and the bugs’ evolving resistance to insecticides is part of the reason for their resurgence. A new study gives the most complete picture so far of the adaptations some bedbugs have developed to thwart exterminators’ poisons....

Maybe The First Discovered Exomoon Doesn T Exist After All

Two years ago, a group of scientists made an exciting announcement: They had discovered the first moon orbiting a planet around another star, a.k.a. the “exomoon.” Data from the Kepler Space Telescope indicated that the planet Kepler-1625b had a moon around it, and that was later backed up by observations from the Hubble telescope.At least that’s what we thought at the time. But new research by a different group of scientists indicates that perhaps this exomoon might not exist after all....

Nasa Says Two Of Its Rockets Failed Because Of Metals Fraud

In 2009, NASA attempted to launch a weather satellite into space. Unfortunately, the rocket’s fairing failed to open and the launch failed. Now, a decade later, we finally know why: NASA says that its contractor for the fairing, Sapa Profiles, committed extensive metals fraud.Sapa Profiles was contracted to manufacture parts for the fairings on two NASA satellite launches—the one in 2009 and another failed launch in 2011. These parts needed to be made of a highly specific aluminum alloy that met rigorous standards for strength and durability, and according to a recent court plea, the company did not do that....

The Marines 3D Printed A Concrete Barracks

This Is Nasa S Very First Idea For A Space Station

Few people remember today, but before President Kennedy made his famous call in 1961 to land on the Moon by the end of the decade, the lunar surface wasn’t NASA’s intended destination. Instead, NASA had envisioned an Earth-orbiting space station as its first big goal. And while space station ideas can be traced back all the way to the 19th century, NASA’s Atlas Orbital System design of the late 1950s was probably the first technically sound idea based primarily on available technology....

Top 10 Fun Mpg Friendly Cars You Can T Buy In America Yet

2009 Mercedes-Benz A-ClassMedia Platforms Design TeamTo many, it’s an open question as to whether Mercedes-Benz should even be in the minicar business. And the original terribly built, terrible driving A-Class (introduced back in 1997) didn’t help make the case for such a small car. But the A-Class is updated for 2009 and it’s now the sort of car that may well make sense for a newly fuel-conscious America.While the A-Class is as boxy as other hatchbacks in its class, it manages to be distinctive because this tiniest of Benzes carries traditional Mercedes styling cues....

Why I Want To Put A Kindle In Space

I have a weird idea. I want to put a Kindle in space. Not literally (or for literature)—instead, I want to take the technology of a Kindle’s E Ink screen and put it on the side of a spacecraft to help control temperature and maybe even do some basic navigation. It might be crazy. It could be brilliant. But space is tough. Satellites cost tens to hundreds of millions of dollars, have to operate for years, and must be reliable, since there’s no way to fix them in space....

Germany, a major pioneer of submarine warfare, finds itself with its entire submarine fleet out of action. All six of the country’s Type 212A attack submarines are out of commission, and the reasons stretch from an underfunded defense establishment to a shortage of sailors. The total absence of any usable u-boats, a key capability as Russia continues to intimidate Germany’s NATO allies, calls into question Berlin’s commitment to defense.Germany has six Type 212A diesel electric attack submarines....
