AAAS at the BA: Whale food, winners and losers in Antarctica and solar insights

Climate clues from the Earth’s poles – swarming whale food, winners and losers in Antarctic waters, and solar insights at the BA 2002 Annual Meeting

The latest thinking on the chances of extinction for Antarctic animals in seas and lakes, whale food hiding beneath sea ice, and new insights on the Sun’s spin are among the hot topics slated for discussion at today’s Frontiers of Polar Science panel, organized by the American Association for the Advancement of Science (AAAS), through i

New Procedure Kills Liver Tumors Without Surgery; Cures Some, Extends Life For Others

The week after Carlton Harris underwent a novel therapy at the Duke Comprehensive Cancer Center to destroy three cancerous liver tumors, he was back at the gym huffing, puffing, lifting and sweating. Not even a single stitch to show for his trouble, Harris wore only a small bandage to cover the three tiny holes — the size of a snake-bite — where wire probes entered his skin and literally burned away the cancerous tumors inside his liver.

So simple is the new procedure — called radiofrequ

NASA scientists determined to unearth origin of the Iturralde Crater

NASA scientists will venture into an isolated part of the Bolivian Amazon to try and uncover the origin of a 5 mile (8 kilometer) diameter crater there known as the Iturralde Crater. Traveling to this inhospitable forest setting, the Iturralde Crater Expedition 2002 will seek to determine if the unusual circular crater was created by a meteor or comet.

Organized by Dr. Peter Wasilewski of NASA’s Goddard Space Flight Center, Greenbelt, Md., the Iturralde Crater Expedition 2002 will be l

The CEBAF Large Acceptance Spectrometer (CLAS) delves into secrets of particle’s structure

Jefferson Lab researchers utilize CLAS and CEBAF’s 5.7 GeV continuous beam to gather new insights on several fundamental questions about the neutron

The CEBAF Large Acceptance Spectrometer (CLAS) is like a perfect survey instrument. Because it surrounds the interaction point in Jefferson Lab’s Hall B, it can record several particles produced in a subatomic interaction at once. More than 40,000 data channels convey information on the trajectory (measured with drift chambers),

Navigate via the web with the SisNet receiver

Knowing your precise position anytime via the internet is now possible thanks to the Signal in Space through Internet (SisNet) technology developed by the European Space Agency.

This technology combines the powerful capabilities of satellite navigation and the internet. As a result, the highly accurate navigation information that comes from the European Geostationary Navigation Overlay Service (EGNOS) Signal-in-Space (SIS) is now available in real time over the internet.

New system for storing lithium-polymer energy

The basque technology centre CIDETEC is working on a project about lithium-polymer energy with the collaboration of the companies CEGASA and ZIGOR.

Actually, they are in the first stage of the project. Initially, they analysed the structure, design and development of different electrode materials with multiple characteristics (cathode and anode) to use lithium-polymer in batteries.

The results of the project enabled the development of a lab-scale prototype of a rechargeable
