ICE, ICE, BABY For years, Death Valley presented visitors with a mystery: those of the famed “sliding rocks.” What made these small boulders seemingly glide across the playa, leaving tilled soil tracks in their wake? The answer appears in the scientific journal PLOS One: a layer of ice, and a push from the wind. Nature’s game of curling, we’d guess.

As many as 75 scientists from the Centers for Disease Control and Prevention may have been exposed to live anthrax bacteria after potentially infectious samples were sent to laboratories unequipped to handle dangerous pathogens, a spokesman for the federal health agency said Thursday.
The agency was testing a new way to kill anthrax, which they discovered did not work as well as they expected.
None of the potentially infected scientists have any symptoms, but a number of them are being treated with antibiotics “out of an abundance of caution,” the spokesman, Thomas Skinner, said.
The lapse occurred sometime from June 6 to June 13. Workers in three labs who were not wearing protective gear moved and experimented with samples of the highly infectious bacteria that were supposed to have been deactivated, the agency said.
It added in a statement that procedures used in two of those laboratories in Atlanta, where the C.D.C. is based, may have “aerosolized the spores,” essentially blowing the bacteria into the air. The exposure was discovered June 13, when the bacterial plates were collected for disposal and live B. anthracis colonies, or anthrax bacteria, were found.
“The likelihood that anyone was actually exposed is very small,” Mr. Skinner said.
Anthrax infects humans by touch, by inhalation or by consuming it. The inhaled form is the most dangerous, and among the 18 such cases identified in the United States during the 20th century, the fatality rate was around 75 percent, according to the C.D.C.’s website. After the terrorist attack in fall 2001 in which B. anthracis spores were released through the mail, five of the 11 people who were ill died.

A misshapen nucleus is bad news. For any given cell, the nucleus — the home of most of a cell’s genetic material — generally takes a fairly consistent shape. But when things go wrong and disease takes hold, the nucleus can become deformed.

This headline is misleading.
It should read “Conservatives Lose Climate Change Debate to Bill Nye. Like, Badly.”
