Glowing Hearts

March 12, 2006

Cornell University researchers have developed genetically engineered mice that have a fluorescent molecule which glows when the heart contracts. The molecule, known as green fluorescent protein (GFP), is derived from bioluminescent jellyfish. It was incorporated into these mice so that the fluorescence is linked to the release of calcium by the muscle cells of the heart. Because the release of calcium is necessary to cause the rhythmic contraction of the heart, the investigators were able to view this process as different areas of the heart began to glow. Their studies have led to new information of embrylogic development of the heart.

There is a nice image from their study on Technovelgy (link below).

burntNow this is hot! Scientists from the Sandia National Laboratories in Albuquerque, New Mexico were able to generate the highest temperature ever recorded on Earth, an amazing 3.6 billion degrees Farenheit. The laboratory is part of the U.S. Department of Energy. A snip from the LiveScience.com article:

Scientists have produced superheated gas exceeding temperatures of 2 billion degrees Kelvin, or 3.6 billion degrees Fahrenheit.This is hotter than the interior of our Sun, which is about 15 million degrees Kelvin, and also hotter than any previous temperature ever achieved on Earth, they say.

News of the product behind the much hyped Microsoft Origami project was released today. The product is a small keyboardless computer, dubbed the Ultra-Mobile PC, that runs Windows. The machine will have WiFi capabilities (with the option of connecting to a Bluetooth enabled wireless phone so that the internet will never be out of reach) and will offer extensive multimedia support. Evidently, it is intended to be an all-in-one work/entertainment machine.

Will this be the next big gadget? I’m looking forward to getting my hands on one to try it out.

crustaceanFrench researchers have discovered a new crustacean species that is white with a thick covering of fine fur over its claws and legs. It was discovered in 7,500 feet of water in the South Pacific and is so unusual that it was assigned a new family name, Kiwaida, after the Polynesian goddess of shellfish.

Scoble is knocking down readers’ guesses one by one about what the Microsoft Origami actually is. Do you think that you know? Leave a comment on his post. He’ll tell you if you’re right.

Apparently, we’ll all find out on Thursday. Check http://channel9.msdn.com Thursday for more information.
