Fresh analysis of an extinct relative of humans suggests our ancient ancestors dined primarily on tiger nuts, which are edible grass bulbs, settling a discrepancy over what made up prehistoric diets. According to a new study published in the journal PLOS One, the strong-jawed ancient hominin known as Paranthropus boisei, nicknamed “Nutcracker Man,” which roamed East Africa between 2.4 million and 1.4 million years ago, survived on a diet scientists previously thought implausible.

New research into Pompeiians' daily lives is broadening our understanding of this ancient Roman culture, particularly their eating habits, before Mt. Vesuvius brought it all crumbling down nearly 2,000 years ago. Over the past decade, archaeologists excavating a row of building plots discovered remnants of food that would have been widely available and inexpensive in ancient Italy, like grains, fruits, olives, lentils, local fish, nuts and chicken eggs. They also uncovered evidence that Pompeiians enjoyed a variety of exotic foods, some of which would have been imported from outside Italy, including sea urchins, flamingos and even the butchered leg joint of a giraffe.

Uses for 3D printers are more widespread than ever, but researchers in Germany are expanding 3D-printing territory even further. For the first time ever, scientists from the Department of Radiology at Charité Campus Mitte in Berlin have recreated dinosaur fossils from blueprints made by computed tomography, or CT, scans. The ability to scan and 3D-print dinosaur fossils could have wide-ranging applications for not only paleontologists but also educators and private collectors alike.

Astronomers have warned that our planet is long overdue for a defense plan against catastrophic asteroid collisions. When it comes to deflecting Earth-obliterating celestial bodies, short of a superhero capable of punching the approaching rock back into outer space, there is no single force dedicated to stopping cosmic bullies from striking our little blue planet straight in the eye. That’s why the United Nations said it will establish an International Asteroid Warning Group to intercept and divert dangerous asteroids.

Scientists at the University of Texas looked at the interactions between bacteria in 3D-printed environments to better understand what makes some microbes resistant to antibiotics, something health officials have been warning us about for a long time. They used high-precision lasers to print multiple two-dimensional images, using a chip modified from a digital movie projector, onto a layer of flexible gelatin where bacteria were growing. As layers of protein were added to the gelatin, which contains photosensitive molecules that become aroused and bond together after being hit with a laser, they formed a tiny encasing around the bacteria.

Guilford County Schools' headline grabbing tablet program is back in the news again. The program came to an abrupt end last Friday when the school district announced that they were recalling all of the Amplify tablets. GCS had leased over 15 thousand of the tablets (at a cost of $200 a year) for its middle school students, but decided to recall the tablets just one month into the school year after some 1500 students reported a broken screen. Around 2 thousand complained of improperly fitting cases, and there were also 175 reports of malfunctioning power supplies. There's currently no explanation for the cases or power supplies, but GCS has stated that the tablets broke because they lacked a layer of Gorilla Glass. This was listed in the contract, but the school district did not confirm the condition of the tablets before accepting them.
This program was the poster child for Newscorps' entry into the educational market. It was the single largest program to use the Amplify tablet, and its failure represents a serious setback. The Amplify tablet now has a record for poor construction quality and a breakage rate that is 12 times higher than what Squaretrade reported in early 2012 for the iPad 2.
