Ladies Last: 8 Inventions by Women That Dudes Got Credit For October 15 is Ada Lovelace Day, named for the world's first computer programmer and dedicated to promoting women in STEM—science, technology, engineering, and math. A Victorian-era mathematical genius, Lovelace was the first to describe how computing machines could solve math problems, write new forms of music, and much more, if you gave them instructions in a language they could understand. Of course, over the ensuing 100-plus years, dudes have been lining up to push her out of the picture (more on that below). Lovelace is hardly the only woman to be erased from the history of her own work. Here's a quick look at eight women whose breakthroughs were marginalized by their peers. (This isn't a complete list, by tragically epic degrees.

Thorium-Fueled Automobile Engine Needs Refueling Once a Century By: David Russell Schilling | October 28th, 2013 Thorium Concept Car - Image Courtesy There are now over one billion cars traveling roads around the world directly and indirectly costing trillions of dollars in material resources, time and noxious emissions. Imagine all these cars running cleanly for 100 years on just 8 grams of fuel each. Laser Power Systems (LPS) from Connecticut, USA, is developing a new method of automotive propulsion with one of the most dense materials known in nature: thorium.

'All Clear' UV Light Bottle Purifies Water in 60 Seconds On Friday afternoon, I plugged my water bottle into a laptop USB port for a charge. Saturday found me in the woods of Wisconsin, dipping the bottle into a lake then pressing a button to purify its contents for a drink. The $99 bottle, called the All Clear UV Microbiological Water Purifier, is made by CamelBak. It uses UV light to render microbes harmless, letting you grab a drink almost anywhere.

3D-Printed Human Cells Will Replace Animal Testing in Five Years, Says Bioengineer Expert 3D-printing could soon bring about an end to animal abuse in drug testing, according to bioengineering expert Alan Faulkner-Jones. Speaking at the 3D Printshow Hospital in London, the Heriot Watt University researcher said that 3D-printed human cells could eliminate the need to test new drugs on animals as soon as 2018. Using a bio-printer hacked together from a MakerBot printer, Faulkner-Jones demonstrated how human stem cells can be printed into micro-tissues and micro-organs.

Accidental discovery dramatically improves electrical conductivity Quite by accident, Washington State University researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to light. The effect, which lasted for days after the light was turned off, could dramatically improve the performance of devices like computer chips. WSU doctoral student Marianne Tarun chanced upon the discovery when she noticed that the conductivity of some strontium titanate shot up after it was left out one day. At first, she and her fellow researchers thought the sample was contaminated, but a series of experiments showed the effect was from light.

The Third Carbon Age by Michael T. Klare When it comes to energy and economics in the climate-change era, nothing is what it seems. Most of us believe (or want to believe) that the second carbon era, the Age of Oil, will soon be superseded by the Age of Renewables, just as oil had long since superseded the Age of Coal. President Obama offered exactly this vision in a much-praised June address on climate change. True, fossil fuels will be needed a little bit longer, he indicated, but soon enough they will be overtaken by renewable forms of energy.

Russia, Turkey pivot across Eurasia Russia, Turkey pivot across Eurasia By Pepe Escobar The latest, spectacular "Exit South Stream, Enter Turk Stream" Pipelinistan gambit will be sending big geopolitical shockwaves all across Eurasia for quite some time. This is what the New Great Game in Eurasia is all about. In a nutshell, a few years ago Russia devised North Stream - fully operational - and South Stream - still a project - to bypass unreliable Ukraine as a gas transit nation.
