Meet the Makers of an Exotic (Partially) 3-D Printed Car (2 Videos)

Slashdot - Wed, 01/07/2015 - 8:46pm
Last month, in a story headlined 3D Printed Supercar Chassis Unveiled, we promised video interviews with builders Kevin and Brad "in the near future." Here they are. First, we have Kevin Czinger, Founder & CEO of Divergent Microfactories. He says the way we build cars is more important from an environmental standpoint than how we fuel them, and that the way we make cars now is a lot less efficient and a lot more expensive than it needs to be. Divergent's first demo vehicle, the Blade, is a tandem-seating 700 HP supercar its makers say does 0 - 60 in 2.5 seconds. Price? No word yet, but it's safe to assume "plenty" might be an accurate guess. In the second video, Blade project lead Brad Balzer goes into detail about how, why, and where they use 3-D printing, and explains the modular nature of their car chassis design. He says they don't need to change many parts to go from ultra-sports car to pickup truck. He also says that while Divergent Microfactories is working on cars right now, their manufacturing system can be applied to many different industries. Indeed, their long-range goal is to help people build microfactories making many different kinds of products faster, more flexibly, and for less money than it takes to make similar manufactured items today. Note: The transcript covers both videos and has a little 'bonus' material in it, too.

Microsoft To Launch Minecraft Education Portal For Teachers

Slashdot - Wed, 01/07/2015 - 8:01pm
Mickeycaskill writes: Microsoft wants to help educators use Minecraft to teach pupils about maths, history, creative design and other subjects and skills, claiming the game is already being used in classrooms in the US and UK. Minecraft developer Mojang was bought by Microsoft last year for $2.5 billion and the game has been featured in a number of HoloLens demos, an indication of how it sees the former indie phenomenon as more than just a game. "Very soon after Minecraft launched, we noticed teachers bringing the game into their classrooms," said a blog post. "Often inspired by the passion of their students, they started using Minecraft to design history lessons, teach language classes, explore mathematics, physics, computer science, writing, and more."

Dagger-like canines of saber-toothed cats took years to grow

Science Daily - Wed, 01/07/2015 - 7:18pm
The fearsome teeth of the saber-toothed cat Smilodon fatalis fully emerged at a later age than those of modern big cats, but grew at a rate about double that of their living relatives. The findings, for the first time, provide specific ages for developmental dental events in Smilodon. The eruption rate of the cat's permanent upper canines was a speedy six millimeters per month, but the teeth weren't fully developed until three years of age.

Google Apologises For Photos App's Racist Blunder

Slashdot - Wed, 01/07/2015 - 7:16pm
Mark Wilson writes: Google has issued an apology after the automatic tagging feature of its Photos apps labeled a black couple as "gorillas". This is not the first time an algorithm has been found to have caused racial upset. Earlier in the year Flickr came under fire after its system tagged images of concentration camps as sports venues and black people as apes. The company was criticized on social networks after a New York software developer questioned the efficacy of Google's algorithm. Accused of racism, Google said that it was "appalled" by what had happened, branding it as "100% not OK".

Pew Survey Documents Gaps Between Public and Scientists

Slashdot - Wed, 01/07/2015 - 6:33pm
PvtVoid writes: A new Pew Research Study documents an alarming gap between public perception of scientific issues and the opinions of the scientists themselves, as measured by a poll of AAAS scientists. Even worse, the gap is partisan, with clear differences between Republicans and Democrats, and between conservatives and liberals. For example, while 98% of AAAS members agree with the statement that "Human beings and other living things have evolved over time", only 21% of conservatives agree, compared with 54% of liberals. Global warming, similarly, shows an ideological gap: 98% of AAAS scientists agreed with the statement that "the Earth is getting warmer mostly due to human activity", compared with 21% of conservatives and 54% of liberals. Encouragingly, almost everybody thinks childhood vaccines should be required (86% of AAAS members, 65% of conservatives, and 74% of liberals.) Go here for an interactive view of the data.
