A paper published today in the American Geophysical Union’s Journal of Geophysical Research-Oceans shows a method to recover valuable data from the primary tool used for measuring global sea level – satellite radar altimetry. Altimeter data are used, among other benefits, to monitor and predict the occurrence of events such as El Niño and La Niña – a coupled ocean-atmosphere phenomena that can alter global weather patterns.
Some six percent of global altimetry measurements are typically discarded because the instrument can’t get accurate readings in areas of ocean calm or “slicks” caused by a lack of wind and waves, or by surface films created by blooms of phytoplankton or oil spills. Because millions of altimeter measurements are made per year, that six percent translates into a huge amount of unused data.
The improvement comes from a modeling technique developed by scientists that should enhance and expand the number of altimeter measurements that NASA can collect – using the Jason-1 satellite – from the equatorial Pacific Ocean where El Niño events originate. Jason-1, launched in 2001, is a joint NASA/Centre National dÉtudes Spatiales or CNE (the French government space agency) mission.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
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
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
