$9 Computer with Built-in WiFi

Its Kickstarter description says CHIP is a computer for students, teachers, grandparents, children, artists, makers, hackers, and inventors. It includes a fully integrated battery power circuit that allows you to make your project mobile with just a 3.7v LiPo battery. The dev board-looking device has specifications at par with standard traditional computers: 1GHz processor, 512MB … Read more

Color 3D Printing

Mosaic Manufacturing recently made waves with the launch of the Palette, a system for printing multi-colored 3D objects. It prints in multiple colors by cutting snippets of colored filament from different spools and then melting them together inside the device’s plain enclosure. A separate sensor can tell the current filament position and ensures that the … Read more

A 3D-Printed Jet Engine

Researchers at GE recently built a miniature, backpack-sized jet engine that they made entirely from 3D-printed parts. And not just for looks, either. They were able to fire it up and get it moving to 33,000 rpms. The engine was built over the course of several years, using a 3D printing technique that melted thin … Read more

Game Changing Battery

Tesla will finally be passing along details on its long-awaited batteries designed for home use, plus a “utility-scale” battery. They will likely be manufactured in its new Gigafactory in Nevada. A Tesla spokesperson has confirmed the announcement: “We have decided to share a bit about what we will announce on the 30th,” Jeff Evanson, Tesla’s … Read more

Nutrition and COPD

A recent study found COPD patients who ate more of four foods – fish, grapefruits, bananas and cheese – seemed to have better lung function. Antioxidants might be the reason, although that’s far from proven. COPD, or chronic obstructive pulmonary disease, is an umbrella term for emphysema and chronic bronchitis – two progressive lung conditions … Read more

Closing the Nutrient Gap

While the dollar skew in science is seemingly all pervasive, the recent declarations concerning the efficacy, or lack thereof, in vitamin and mineral supplements would appear to betray the corporate line. On the one hand, big-agri would like you to believe that nutrient rich foods can be produced from nutrient depleted soils. On the other hand, big-pharma … Read more

Red Meat and Cancer

A sugar that naturally occurs in animals but not humans could be the reason why people are at higher risk for cancer when they consume red meat, researchers at the UC San Diego School of Medicine reported Monday. The scientists found that feeding the sugar Neu5Gc to mice engineered to be deficient in it — … Read more

Making the Most of Wind Power

Wind power accounts for roughly 2.5 percent of total worldwide electricity production but is growing a rate of about 25 percent annually. For as long as ships needed to be propelled, sails have been employed to make use of wind energy. Windmills provided mechanical power for centuries and wind pumps lifted water out of the … Read more
