Networking initiative to support interdisciplinary research By News Releases (European Space Agency) Specialists from various Earth system science disciplines recently gathered to address a major question: what will our environment look like in the future?

Galaxy study validates general relativity on cosmic scale, existence of dark matter By News Releases (University of California - Berkeley) While general relativity describes well the behavior of the solar system, Einstein's theory of gravity and spacetime has not been tested on cosmological scales. Now, a team that includes UC Berkeley physicist Uros Seljak has analyzed data on 70,000 galaxies to show that the theory is so far the best description of the universe, at least out to 3.5 billion light years from Earth. Specifically, theories without dark matter do not fit the observations.

Mysterious cosmic 'dark flow' tracked deeper into universe By News Releases (NASA/Goddard Space Flight Center) Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra. A new study led by Alexander Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Md., tracks this collective motion -- dubbed the "dark flow" -- to twice the distance originally reported.

Low strengthens into Hubert, making landfall in Madagascar By News Releases (NASA/Goddard Space Flight Center) The low that forecasters were watching for development yesterday, March 9, strengthened into Tropical Storm Hubert, and is already making landfall in eastern Madagascar.

90Q: A curious short-lived 'tropical' cyclone in the southern Atlantic By News Releases (NASA/Goddard Space Flight Center) Tropical cyclones typically don't form in the Southern Atlantic because the waters are usually too cool. However, forecasters at the Naval Research Laboratory noted that a low pressure system off the coast of Brazil appeared to have tropical storm-force winds yesterday.

Laptop revolution: New class design saves schools money, space By News Releases (North Carolina State University) Universities around the country are struggling with shrinking budgets, even as they need to cater to the needs of an increasing number of students. New research from North Carolina State University shows that one way to cut down on costs, and simultaneously improve the learning experience, is to have students use the technology they already bring into the classroom.

Tropical cyclone formation likely near Madagascar By News Releases (NASA/Goddard Space Flight Center) Forecasters are watching a low pressure area located off the east coast of Madagascar that appears ripe for development in the Southern Indian Ocean. If it becomes a tropical storm, it would be named Hubert.

Co-orbital restricted three-body problem and its application By News Releases (Science in China Press) Researchers from China and Germany have shown an approximate semi-analytical solution for the planar co-orbital circular restricted three-body problem, which has been applied to the motion of the barycenter of the planned gravitational observatory LISA constellation, extend the applicable region to the timescale of 1000 years. The study is reported in Issue 53 No.1 of Science China Physics because of its significant research value.

Navy scientists support Haiti relief operations By News Releases (Naval Research Laboratory) Scientists at the Naval Research Laboratory at Stennis Space Center are supporting Haiti relief operations. The Marine Geosciences Division's Geospatial Sciences and Technology branch is providing a specially configured version of its patented NRL Tile Server and Geospatial Information Database that will host maps, imagery and other geospatial information for dedicated use in Haiti relief missions.

A high-tech handrest By News Releases (University of Utah) University of Utah engineers developed a computer-controlled, motorized hand and arm support that will let doctors, artists and others precisely control scalpels, brushes and tools over a wider area than otherwise possible, and with less fatigue.
