Santa Claus is the ultimate arbiter of who's been naughty or nice. Given that he controls the world's supply of toys, few would dare to question whether St. Nick himself lands in the "nice" column. But Richard Halpern contends there was one bold soul who risked placing kids' experiences with the jolly old elf on the dark side of the ledger: Norman Rockwell.

Several Johns Hopkins University astronomers describe the decision to strip Pluto of its planetary status as a "muddled" ruling that is unlikely to settle ongoing debates over how to define a planet and whether the term should apply to Pluto. In an informal poll, only one astronomer was pleased to hear about Pluto's new status.

Johns Hopkins scientists have demonstrated that corals can build their skeletons out of different minerals depending on the chemical composition of the seawater around them.
If someone hadn't thought to make team uniforms the same color, we might be stuck watching World Cup soccer matches with only two players and a ref. It is that color coding, psychologists have now demonstrated, that allows spectators, players and coaches at major sporting events to overcome humans' natural limit of tracking no more than three objects at a time.
Johns Hopkins University astrophysicist Adam Riess and two colleagues today were awarded this year's $1 million Shaw Prize in astronomy for their discovery that an unexplained, mysterious "dark energy" is driving an ever-faster expansion of the universe.
Students typically lose one to two months of reading and math skills during summer break. It's the so-called "summer slide." Here are tips for preventing your children from sliding too.

Other Johns Hopkins commencement speakers include Michael Griffin, NASA administrator; Michael Bloomberg, mayor of the New York; and Mohamed ElBaradei, director general of the International Atomic Energy Agency.
Nonprofits are facing pressing needs for investment capital but report widespread obstacles to accessing that capital, according to a new report.
Evidence is mounting that estrogen, a hormone critical to a woman's sexual development, should also be thought of as a neurotransmitter when acting in the brain.
Historian Paul Kramer, in his new book "The Blood of Government," details the long-forgotten history of the Philippine-American war and the 40-year occupation that followed. He argues that the Philippine adventure in many ways parallels the current U.S. occupations of Iraq and Afghanistan.

A teleconference is scheduled for 12 noon EST on Thursday, March 16, to announce findings from the WMAP mission, which observes the oldest light in the universe, probing its infancy and growth.
A research team has for the first time identified a substance in the brain that is proven to cause memory loss.
