World e-waste map reveals national volumes, international flows
By 2017, all of the year's end-of-life refrigerators, TVs, mobile phones, computers, monitors, e-toys and other products with a battery or electrical cord worldwide could fill a line of 40-ton trucks end-to-end on a highway ...
Global warming may dent El Nino's protective shield from Atlantic hurricanes, increase droughts
(PhysOrg.com) -- El Niño, the periodic eastern Pacific phenomenon credited with shielding the United States and Caribbean from severe hurricane seasons, may be overshadowed by its brother in the central Pacific ...
Venus Express unearths new clues to the planet's geological history
(Phys.org) -- ESA's Venus Express has been used to study the geology in a region near Venus' equator. Using near-infrared observations collected by the Venus Monitoring Camera (VMC), scientists have found ...
Polar oceans key to temperature in the tropics
Scientists have found that the ocean temperature at the earth's polar extremes has a significant impact thousands of miles away at the equator.
Biophysicists model the behavior of a protein critical to cell motion
(Phys.org) -- Physicists at Lehigh have created a mathematical model that could benefit researchers who study cell motion, including cancerous cell motion, tissue healing processes and human embryonic development.
Cassini spots tiny moon, begins to tilt orbit
(Phys.org) -- NASA's Cassini spacecraft made its closest approach to Saturn's tiny moon Methone as part of a trajectory that will take it on a close flyby of another of Saturn's moons, Titan. The Titan flyby ...
NASA's Mars rover zeroes in on August landing (Update)
NASA's Mars rover, nicknamed Curiosity, is zeroing in on its August landing on the Red Planet and aims to touch down closer than expected to its mountain target, the US space agency said Monday.
American mathematicians Nash, Nirenberg win Abel math prize
American mathematicians John F. Nash Jr. and Louis Nirenberg have won this year's Abel Prize in mathematics.
Disentangling information from photons
Theoretical physicist Filippo Miatto and colleagues from the University of Strathclyde, Glasgow, UK, have found a new method of reliably assessing the information contained in photon pairs used for applications in cryptography ...
Metamaterials and transformation optics control light on a microchip
Using a combination of the new tools of metamaterials and transformation optics, engineers at Penn State University have developed designs for miniaturized optical devices that can be used in chip-based optical ...
Zoom-up star photos poke holes in century-old astronomical theory
(PhysOrg.com) -- The hottest stars in the universe spin so fast that they get a bit squished at their poles and dimmer around their middle. The 90-year-old theory that predicts the extent of this "gravity ...
Equatorial fish babies in hot water
Scientists have discovered that rising ocean temperatures slow the development of baby fish around the equator, raising concerns about the impact of global warming on fish and fisheries in the tropics.
Outside a vacuum: Model predicts movement of charged particles in complex media
Picture two charged particles in a vacuum. Thanks to laws of elementary electrostatics, we can easily calculate the force these particles exert upon one another, and therefore predict their movements.
