MIT scientists make it easy to tweak designs for 3D printing

Two different groups of MIT researchers found a way to print out objects with glass instead of plastic and to make a printer spew out 10 different materials at once earlier this year. This particular team along with researchers from the Interdisciplinary Center Herzliya in Israel, however, have chosen to focus on creating a system that makes it possible for even novices to customize the objects they want to print. Designers typically have to adjust a CAD file to tweak the object’s looks by typing in numerical values, and then wait for minutes to hours for a simulation software to make sure the final product is viable. The system this group developed dramatically speeds up the process. It displays the design along with sliders representing different parameters — say, the height of a shoe’s heel or the base size and width of a mug — on a web browser. The user can then easily play with the sliders to achieve the look they want. Now, here’s the best thing about it: it won’t let you design unstable structures or anything that can’t be printed or used. Nobody has to spend hours waiting for software to make sure the modified digital object is feasible, and all the user needs to do is to send it straight to the 3D printer.

Privacy-focused Blackphone 2 is ready for pre-order

Blackphone 2, the second iteration of Silent Circle’s privacy-focused handset, is now available for pre-order — assuming you don’t mind reserving a device without knowing its price. The original Blackphone was sold at the flagship-level cost of $629, but remember, this one’s more sophisticated than its predecessor, with its front and rear covered in glass. It has a 5.5-inch 1080p display, and inside, it boasts an octa-core processor, 3GB of RAM and 32GB of storage. What makes it different from other phones with similar specs, though, is that it runs an Android-based platform called PrivatOS which includes a suite of secure apps, including ones for encrypted messaging and voice calls. We saw Blackphone 2 at the Mobile World Congress earlier this year, and we have a preview you can read to know a bit more before you pre-order a unit. The device is expected to arrive sometime in September — if you’d rather get the the Blackphone+ tablet, though, you’ll have to wait a bit more, since Silent Circle hasn’t revealed when that one will be available.

NASA’s LADEE confirms the moon’s atmosphere has neon

NASA’s LADEE ran out of fuel and crashed into the lunar surface in 2014, but not before it collected the data needed to answer some decades-old questions about the moon. One of those is confirming that our natural satellite’s atmosphere contains neon — the same gas used to light up signs in Vegas. Astronomers have been speculating about its presence since the Apollo missions, and now LADEE’s Neutral Mass Spectrometer (NMS) instrument has proven that it exists. It’s even relatively abundant, though the moon’s atmosphere is too thin (it’s actually called “exosphere” due to that reason) to turn it into a glowing orb in the sky. NMS has thus proven that the lunar exosphere is composed mostly of helium, argon and neon. Their main source is solar winds, and they fluctuate over time, as well as exhibit peak times throughout the day. LADEE’s data shows, however, that some of the gases in the exosphere come from the moon itself: The decay of radioactive potassium-40 found in lunar rocks gives rise to argon, while thorium and uranium produce helium. As NASA’s Goddard’s Mehdi Benna said: The data collected by the NMS addresses the long-standing questions related to the sources and sinks of exospheric helium and argon that have remained unanswered for four decades. These discoveries highlight the limitations of current exospheric models, and the need for more sophisticated ones in the future.

Spotify tells iOS users how to avoid iTunes charges and pay less

Spotify isn’t happy that its iOS customers have to pay an additional $3 for a premium subscription if they make the purchase through the App Store. That’s why it’s planning to send them instructions on how to apply for a subscription straight from the company’s website. The Verge got its hands on a copy of the letter, wherein Spotify made clear that “the normal Premium price is only $9.99, but Apple charges 30 percent on all payments made through iTunes.” That ups the total to $12.99, which is only $2 away from Apple Music’s six-person family plan. That email, if you haven’t gotten it yet, contains links that make it easy to cancel Spotify’s auto-renew on iTunes and redirect you to the service’s website. You’ll have to wait until your current month ends before you can subscribe again, but after you do, you won’t have to pay $12.99 again. As Bloomberg notes, Apple doesn’t allow links within apps that allow people to make purchases from external websites. That’s likely what prompted the streaming service to decide on sending an email blast instead of adding a PSA inside the app. The publication also points out that Apple only adds $$$ on top of goods or services if it doesn’t have a competing product. For instance, you apparently don’t have to pay extra if you buy a plane ticket through United Airlines’ iPhone app . Since Cupertino’s new Music streaming service has a lot of competitors in addition to Spotify, it’s facing antitrust investigations in a couple of states.
