Magnetic Portals Connect Sun and Earth 235

Posted by Soulskill from the no-cake-jokes-allowed dept.
MaxwellEdison writes "Scientists have discovered evidence of magnetic portals connecting the Earth and the Sun every 8 minutes. 'Several speakers at the Workshop have outlined how FTEs form: On the dayside of Earth (the side closest to the sun), Earth's magnetic field presses against the sun's magnetic field. Approximately every eight minutes, the two fields briefly merge or "reconnect," forming a portal through which particles can flow. The portal takes the form of a magnetic cylinder about as wide as Earth. The European Space Agency's fleet of four Cluster spacecraft and NASA's five THEMIS probes have flown through and surrounded these cylinders, measuring their dimensions and sensing the particles that shoot through.'"

Submission + - Kodak unveils brighter CMOS color filters (eetimes.com)

Submitted by brownsteve
brownsteve writes: Eastman Kodak Co. unveiled what it says are "next-generation color filter patterns" designed to more than double the light sensitivity of CMOS or CCD image sensors used in camera phones or digital still cameras. The new color filter system is a departure from the widely used standard Bayer pattern — an arrangement of red, green and blue pixels — also created by Kodak. While building on the Bayer pattern, the new technology adds a "fourth pixel, which has no pigment on top," said Michael DeLuca, market segment manager responsible for image sensor solutions at Eastman Kodak. Such "transparent" pixels — sensitive to all visible wavelengths — are designed to absorb light. DeLuca claimed the invention is "the next milestone" in digital photography, likening its significance to ISO 400 color film introduced in the mid-1980's.

Submission + - Intel V8 Octa-Core System, Full Performance Tests

Submitted by MojoKid
MojoKid writes: In the April time frame, details of Intel's dual-socket 8-core system dubbed "V8" became available but only preliminary performance numbers were shown. The platform consists of quad-core Xeon processors in an Intel 5000X chipset-based motherboard, along with FBDIMM (Fully Buffered DIMM) serial memory. This follow-on article goes into significantly more detail on the platform and showcases many more performance metrics on a Windows Vista 64-bit installation. The POV-Ray and Cinebench 95 benchmark numbers alone are something to smile about.

File Sharing — Harmful to Children and a Threat to National Security 342

Posted by ScuttleMonkey from the root-of-all-evil dept.
jkrobin writes to mention that a recent report from the US Patent office calls peer-to-peer file sharing harmful to children and a threat to national security. "Interestingly, the report makes numerous references to RIAA and MPAA legal actions against file actions, as well as cites a 2005 Department of Homeland Security report that government workers had installed file-sharing programs that accessed classified information without their knowledge."
