Corn better used as food than biofuel, study finds
26th June 2017 phys.org | Earth, Tech

Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.

Discovery could lead to sustainable ethanol made from carbon dioxide
26th June 2017 phys.org | Tech

Most cars and trucks in the United States run on a blend of 90 percent gasoline and 10 percent ethanol, a renewable fuel made primarily from fermented corn. But to produce the 14 billion gallons of ethanol consumed annually by American drivers requires millions of acres of farmland.

X-ray eyes in the sky: New method for 3-D through-wall imaging that utilizes drones and WiFi
25th June 2017 phys.org | Tech

Researchers at UC Santa Barbara professor Yasamin Mostofi’s lab have given the first demonstration of three-dimensional imaging of objects through walls using ordinary wireless signal. The technique, which involves two drones working in tandem, could have a variety of applications, such as emergency search-and-rescue, archaeological discovery and structural monitoring.

Sound waves direct particles to self-assemble, self-heal
25th June 2017 phys.org | Tech

An elegantly simple experiment with floating particles self-assembling in response to sound waves has provided a new framework for studying how seemingly lifelike behaviors emerge in response to external forces.

‘Liquid Light’ Can Bend Around Objects in a Frictionless Flow
25th June 2017 | seeker.com | Space, Tech

For several centuries now, scientists have known that light behaves like a wave, expanding out from its source until absorbed or reflected by objects, which are in turn illuminated.

In recent years, however, research has indicated that light can also behave like a liquid — flowing around objects and reconstituting on the other side.

Researchers have found a way to root out identity thieves by analyzing their mouse movements with AI
25th June 2017 qz.com | Tech

Identity theft is often a multi-layered process. Once a thief gets one bit of your information, they try to use it to get more. The hackers behind the 2015 data breach of the US Internal Revenue Service (IRS), for example, used personal information they’d previously stolen from thousands of Americans to answer security questions on the IRS website, and in turn get access to their tax returns.
