Cost gap for Western renewables could narrow by 2025 Posted: 27 Aug 2013 05:45 PM PDT A new study indicates that by 2025 wind and solar power electricity generation could become cost-competitive without federal subsidies, if new renewable energy development occurs in the most productive locations.

NASA'S Mars Curiosity debuts autonomous navigation Posted: 27 Aug 2013 03:40 PM PDT NASA's Mars rover Curiosity has used autonomous navigation for the first time, a capability that lets the rover decide for itself how to drive safely on Mars. This latest addition to Curiosity's array of capabilities will help the rover cover the remaining ground en route to Mount Sharp, where geological layers hold information about environmental changes on ancient Mars. The capability uses software that engineers adapted to this larger and more complex vehicle from a similar capability used by NASA's Mars Exploration Rover Opportunity, which is also currently active on Mars.

Fractions gain traction with real-life models Posted: 27 Aug 2013 01:05 PM PDT For children to understand math, teachers must constantly make the connection between abstract numbers and real world examples, new research shows.

Patent shows promise for improved method of carbon capture Posted: 27 Aug 2013 01:02 PM PDT New research shows a new method for capturing greenhouse gases is potentially cheaper and more energy efficient than current solvents.

Quantum inverted pendulum: Control scheme dynamically maintains unstable quantum system Posted: 27 Aug 2013 10:50 AM PDT Researchers have demonstrated a way to maintain an unstable quantum system by applying bursts of microwave radiation. The technique is comparable to methods used for controlling an inverted pendulum in classical physics.

Researcher controls colleague's motions in first human brain-to-brain interface Posted: 27 Aug 2013 09:27 AM PDT Researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.

New energy model offers transparency to let others replicate findings Posted: 27 Aug 2013 08:31 AM PDT Computer models are used to inform policy decisions about energy, but existing models are generally "black boxes" that don't show how they work, making it impossible for anyone to replicate their findings. Researchers have developed a new open-source model and are sharing the data they put into it, to allow anyone to check their work -- an important advance given the environmental and economic impact of energy policy decisions.

How quickly can a bacterium grow? E. coli can replicate close to thermodynamic limits of efficiency Posted: 27 Aug 2013 08:30 AM PDT All living things must obey the laws of physics -- including the second law of thermodynamics, which states that the universe's disorder, or entropy, can only grow. Highly ordered cells and organisms appear to contradict this principle, but they actually do conform because they generate heat that increases the universe's overall entropy.

Existence of new element confirmed Posted: 27 Aug 2013 06:16 AM PDT An international team of researchers has confirmed the existence of what is considered a new element with atomic number 115. The experiment was conducted at the GSI research facility in Germany. The results confirm earlier measurements performed by research groups in Russia.

Scientists detect magmatic water on moon's surface Posted: 27 Aug 2013 06:13 AM PDT Scientists have detected magmatic water — water that originates from deep within the Moon's interior — on the surface of the Moon. These findings represent the first such remote detection of this type of lunar water.
