Researchers commonly use genetically engineered mice to study cancer, but the animal disease differs slightly from the human one. So researchers have sought to transplant human breast tissue into mice to make a better model. Now Robert Weinberg of the Whitehead Institute for Biomedical Research in Boston and his team have succeeded. [...]
The cells grow into human-like breast tissues, complete with milk ducts. Unlike human breasts, however, the mice's growths sit flush to the chest. Humans are unusual in this respect, says Daniel Medina who studies breast cancer at Baylor College of Medicine at Houston, Texas: "In few other species are breasts pendulous."
The human-breasted mice also develop cancer in much the same way as humans. Scientists think breast cancer starts when one epithelial cell gets a mutation in its DNA and starts dividing wildly into a tumour.
As the medical community tries to care for an American population that grows more overweight each year, Southwest Ambulance is unveiling its new ambulance for patients 450 to 1,000 pounds. The ambulance has an extra-large gurney and a ramp-and-winch system to load patients safely and with dignity, said Dorothy Porter, director of public affairs for Southwest. "I think it's going to become a very popular unit," she said.
The ambulance has a beefed-up suspension system and dual rear wheels to bear the extra weight. But the biggest difference between the bariatric ambulance and a standard one is the size of the gurney and the addition of ramps and an electronic winch to load patients, Porter said. [...]
Viki Alexander, patient care manager of UMC's emergency department, estimated UMC sees five to 10 patients a month who weigh more than 400 pounds. "I've been a nurse for 25 years and we used to occasionally have someone really big, but not as often as we do now," she said. The obese patients, she noted, are also younger than she has seen in the past.

Thousands of optical glass fibers form a matrix and run parallel to each other between the two main surfaces of every block," explained its inventor Áron Losonczi. "Shadows on the lighter side will appear with sharp outlines on the darker one. Even the colours remain the same. This special effect creates the general impression that the thickness and weight of a concrete wall will disappear.
It's kind of neat, but I don't see how this is all that different from glass blocks, given that it only comes in pre-fab bricks. If you could pour it like concrete, that would be something.
"Stacy" takes place at the beginning of the 21st century, when teenage girls around the world have suddenly been dying - after a brief bout of giddiness called "Near Death Happiness" - and rising as flesh-eating zombies. And those zombies can only be destroyed by being cut into 165 pieces.

On the day Gov. Rendell unveiled his budget to a packed House chamber, Rep. William Rieger voted in favor of all six bills that came up. But Rieger wasn't there. The Democrat was home on Feb. 3, 100 miles away in Philadelphia. A wad of paper shoved into his electronic "yea" button atop his desk did the work for him. Similar sights are in plain view on any given session day in the cavernous lower chamber where so-called ghost voting is a tolerated bipartisan tradition.
