Li-ion batteries will last 10 times longer and will charge in a tenth of the usual time

Processing power of today's smart phones and their ability to perform multiple functions are truly amazing. However, a general problem of these devices is the battery life that feeds them. They don't even come close to the performance these smartphones.

This is why many of us need to carry around an additional MP3 player, or, as we go by car, a GPS, although the smartphone meets with success of these functions and more.

Now, a new technology created by researchers at Northwestern University, USA, is about to change that. Engineers have made ​​an electrode for lithium-ion batteries - the rechargeable batteries used for most electronic devices - which could provide gadgets an operating range of ten times longer and duration of recharge from outlet ten times faster than normal.

According to statements of Harold H. Kung, coordinator of the project, even after 150 charges, the new type of battery will still be five times more effective than lithium-ion batteries on the market today…

Messenger probe provides new information about Mercury

Latest observations of the Messenger probe indicate that there is a high density material reservoir inside the closest planet to the Sun: Mercury
Since it entered the orbit of Mercury, a year ago, NASA's Messenger probe has taken nearly 100,000 photographs, it mapped the gravitational field of Mercury and elevation measurements.

Researchers published last week in Science Express new discoveries about the closest planet to the Sun. According to them, the planet's crust is thicker and thinner at low latitudes to the poles, which, together with activity data within Mercury, suggests a liquid outer core. This core radius is 85% of the planet to Earth, where the core is less than 50% of the radius.

However, findings reveal a Messenger mission of ferrous sulphate liquid layer beneath the crust of Mercury.

Regarding Mercury landforms, new study shows changes in elevation smaller than on Mars or the Moon, the most prominent topographic feature in terms of being a bump in a large volca…

Origin of life on Earth revealed by new experiments

Scientists have found new evidence that serve to elucidate a long-sought mystery:

Which was the origin of life on Earth
Research confirms that life on Earth is possible due to comets that bombarded our planet billions of years ago, storing essential ingredients for its appearance here.

Jennifer G. Blank, research team coordinator, described experiments in the laboratory with powerful tools and computer models. Scientists have recreated the conditions inside comets at the moment when they hit Earth's atmosphere at a speed of about 30,000 mph and then crashed on the surface.

The research is part of a broad scientific effort that has the goal to understand how amino acids and other ingredients necessary for life on our planet have appeared several billion years ago. Before then, Earth was a barren and desolated planet. Amino acids are the key ingredient of proteins, "brick" core of all life, from microbes to humans.

The research shows that the key to life would have remained…
