"Facebook friend count linked to brain region size"

By Rob Winters - Published on Thursday, 20 October 2011 09:13

"The number of Facebook friends that people have may be related to the size of brain regions involved in social interaction, research suggests.

In a study published in the journal Proceedings of the Royal Society B Biological Sciences, scientists looked at brain scans of 125 university students in London who were all active Facebook users and counted the number of friends each had on the social network and in real life."

"Former Libyan leader Moammar Gadhafi dead, reports say"

"Col. Moammar Gadhafi, the ousted former Libyan leader who ruled his country for 42 years with caprice and an iron hand, is in rebel hands after being captured in the final assault to take the coastal city of Sirte this morning, according to unconfirmed reports from officials of the country’s new ruling council.

Reuters news agency reported that Col. Gadhafi was wounded in both legs and later died of his wounds. These reports have not been confirmed by Gadhafi troops.

The U.S. state department says it cannot confirm media reports of Col. Gadhafi's alleged capture."

"To be great, it may take more than practice"

"MICHIGAN STATE (US) — Can practice, practice, practice alone produce greatness? New research finds working memory capacity may be the deciding factor between being good or being great.

The concept runs counter to previous arguments such as those from Malcom Gladwell of the New Yorker and David Brooks of the New York Times that argue intelligence plays a role in greatness—but only to a point. Beyond that, they say, it’s all about practice."

"Cut the Cable! Build Your Own Digital TV Antenna"

By Rob Winters - Published on Wednesday, 19 October 2011 08:01

"Cable bills busting the budget? you may be missing out on free TV. Using scrap wire with stock lumber, build a slick homemade antenna and stay tuned.

1.) Gather Parts

This antenna spins to orient a pattern of wires, known as an array in engineerspeak, toward broadcasting towers. Rabbit ears and some other older antennas can’t receive high-frequency digital TV transmissions (but if you have an old antenna, try it). To assemble this DIY design, get 32-inch- and 6-inch-long 1 x 4 pine boards; eight 17-inch lengths and two 34-inch lengths of bare 12-gauge copper wire (for the ears and phasing bars); heat-shrink tubing; and 10 No. 8 ½-inch round-head wood screws and fender washers. Buy an impedance-matching transformer (IMT) to maximize signal transmission from channels at different frequencies."

"Frozen Puck Hovers Over Track Using Quantum Levitation"

By Rob Winters - Published on Wednesday, 19 October 2011 07:54

"Researchers at the school of physics and astronomy at Tel Aviv University have created a track around which a semiconductor can float, thanks to the phenomenon of “quantum levitation“.

This levitation effect is explained by the Meissner effect, which describes how, when a material makes the transition from its normal to its superconducting state, it actively excludes magnetic fields from its interior, leaving only a thin layer on its surface.

When a material is in its superconducting state — which involves very low temperatures — it is strongly diamagnetic. This means that when a magnetic field is externally applied, it will create an equally opposing magnetic field, locking it in place."
