Making the case that some of the tax increases that would partly pay for President Obama's $447 billion jobs bill are aimed at Americans who are not that rich, the Senate's Democratic leaders are proposing a 5 percent tax on annual incomes above $1 million instead.
Daniel Schectman, left, discusses the quasicrystal's structure with collaborators in 1985, just months after shaking the foundations of materials science. Schectman was awarded the 2011 Nobel Prize for chemistry.
If you or your mate shaved this morning with one of those thin-foil electric shavers, that face probably brushed up against a strange form of matter called a quasicrystal. Norelco is unlikely to get a Nobel Prize for that invention, but the man who discovered quasicrystals, Daniel Shechtman, will get this year's Nobel Prize in chemistry. And it didn't come easy.
Crystals, like diamonds and quartz, hold their sparkly allure because of the way the atoms inside those rocks line up so neatly.

With Halloween rapidly approaching, you've probably heard about the shortage of pumpkins along the East Coast caused by the flooding rains of Hurricane Irene.
But while you may have troubling finding just the right shape or the right price for your jack o'lantern this year, there's good news for those looking ahead to the pies and cakes of Thanksgiving and Christmas.
In a first attempt (top), researchers removed an egg's genetic material and replaced it with the genes from an adult skin cell. These embryos didn't grow. The researchers tried another method: They left the egg's original genetic material in, but then also added genetic material from an adult cell (bottom). These embryos started growing.
This image shows the chromosomes from one of the cloned cells. Notice there are three sets of each chromosome; normal cells have just two copies of each chromosome.
Researchers in New York are reporting an advance in creating cloned human embryos. The embryos would not be used for reproduction, but rather the creation of embryonic stem cells. Many scientists believe that human embryonic stem cells made this way could revolutionize medicine.
The advantage of stem cells made this way is that they could be personalized to an individual.
In 2005, death penalty opponents protest the impending execution of condemned inmate Frances Newton in Huntsville, Texas. Newton was convicted of killing her husband and two children in their Houston apartment. She was put to death by lethal injection on Sept. 14, 2005.

Private bankers who serve some of the world's richest families are seeing clients pile money into "catastrophe portfolios" and real estate, seeking defensive positions that might help them weather a far-reaching economic storm that has roiled financial markets worldwide.
The Rev. Fred Shuttlesworth, a pioneer of the civil rights movement, died Wednesday in Birmingham, Ala. Shuttlesworth led Birmingham's battle against segregation — a battle that focused the national spotlight on the violent resistance to equal rights in the South and forced change. He was 89.
As Birmingham goes, so goes the nation. That belief was the driving force behind Shuttlesworth's crusade for equality.
"He was the soul and heart of the Birmingham movement," Georgia Congressman John Lewis said. It was Birmingham, he said, that brought the Civil Rights Act of 1964.

Civil rights leader Rev. Fred Shuttlesworth has died, according to reports. He was 89. In the 1950s, Shuttleworth's activism resulted in beatings and attempts on his life in Birmingham, where he established the Alabama Christian Movement for Human Rights in 1956.
