86% of teens in study have traces of BPA in their bodies

A vast majority of teenagers in a recent study had traces of Bisphenol A ( BPA ) inside of their bodies, according to the University of Exeter . They tested 94 17 to 19-year-olds and found BPA in 86 percent of them. The researchers are calling for better packaging labels to allow people to pick BPA-free products. The University of Exeter described BPA as an endocrine-disrupting industrial chemical , which has been in use since the 1960s to create some kinds of plastic . Prior research from the Exeter team discovered BPA can cause “changes to the expression of oestrogen-responsive genes, and the regulation of hormones.” And this recent study, published online earlier this month in BMJ Open , reveals a large number of the teens tested had measurable levels of BPA in their urine: an average of 1.9 nanograms per milliliter.

They worked to avoid BPA-containing plastic packaging, utilize glass or stainless steel containers for drinks and food, and microwave food in glass or ceramic containers. The study found overall, these efforts seemed to do little to help: most teens didn’t see a decrease in exposure. Only some of the teenagers with the highest BPA levels saw some reduction. The industrial chemical seems to be so ubiquitous even working to lower exposure doesn’t have a measurable impact overall, according to the university. University of Exeter associate professor of molecular genetics Lorna Harries said in a statement, “Our study shows that we currently do not have much of a choice about being exposed to BPA. We believe that much better labeling of products containing BPA is needed so people can make an informed choice.” + University of Exeter + BMJ Open Images via Depositphotos and Vinicius Amano on Unsplash

NASA officially logs Elon Musk’s Tesla Roadster as a celestial object

Elon Musk’s red space -traveling Tesla Roadster continues to make history. NASA has now officially listed the vehicle as a celestial object – in the same system tracking bodies in the solar system like planets. Meteorologist Eric Holthaus tweeted the news and a link to the NASA Jet Propulsion Laboratory’s HORIZONS Web-Interface so you can check it out – and the listing reveals a few details about what else was aboard that Roadster. Gizmodo shared instructions for how to see NASA’s listing of the Tesla Roadster: once you click on the HORIZONS link: “click ‘change’ next to the target body, type in ‘ SpaceX ,’ hit enter, then click ‘Generate ephemeris.’” The Tesla Roadster is now described as a spacecraft , and the listing mentions the car’s passenger, a mannequin in a spaceman suit nicknamed Starman.

A data storage device placed inside the car contains a copy of Isaac Asimov’s ‘Foundation’ novels. A plaque on the attachment fitting between the Falcon Heavy upper stage and the Tesla is etched with the names of more than 6,000 SpaceX employees.” Musk recently shared on Instagram what he said will be the last photo of Starman on the way to Mars orbit and from there, the asteroid belt. Last pic of Starman in Roadster enroute to Mars orbit and then the Asteroid Belt A post shared by Elon Musk (@elonmusk) on Feb 7, 2018 at 2:00pm PST The HORIZONS System “provides access to key solar system data and flexible production of highly accurate ephemerides for solar system objects (755,287 asteroids , 3,510 comets , 178 planetary satellites, eight planets, the Sub, L1, L2, select spacecraft, and system barycenters),” per the website . It seems Musk’s Tesla Roadster is now among those select spacecraft. + HORIZONS Web-Interface Via Eric Holthaus and Gizmodo Images via Elon Musk on Instagram , HORIZONS Web-Interface screenshot , and NASA/JPL-Caltech
