Using satellites, data from buoys and computer models to study the Earths oceans, scientists have concluded that more energy is being absorbed from the Sun than is emitted back to space, throwing the Earths energy "out of balance" and warming the planet.
Scientists from the National Aeronautics and Space Administration (NASA) (Washington, D.C.), The Earth Institute at Columbia University (New York), and Lawrence Berkeley National Laboratory (California) have confirmed the energy imbalance by precisely measuring ocean heat content occurring over the past decade.
The study, which appears in this weeks Science Express, a feature of Science magazine, reveals that Earths current energy imbalance is large by standards of Earths history. The current imbalance is 0.85 watts per meter squared (W/m2) and will cause an additional warming of 0.6 degrees Celsius (1 degree Fahrenheit) by the end of this century. This is equal to a 1-watt light bulb shining over an area of one square meter or 10.76 square feet. Although seemingly small, this amount of heat affecting the entire world would make a significant impact. To put this number in perspective, an imbalance of 1 W/m2 maintained for the last 10,000 years is enough to melt ice equivalent to 1 kilometer (6/10ths of a mile) of sea level.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
