Reading a clock is one thing; really knowing the time is quite another. For everyday timekeeping needs, we use a standard known as Coordinated Universal Time, or UTC, which is derived from International Atomic Time, a consensus of more than 200 clocks tha

A strong material inspired by abalone shells could be applied over large areas.

A French spacecraft designed to discover new worlds beyond our solar system has made one of its most significant finds yet--a planet that looks like a cousin to those in our own celestial backyard. COROT 9 b, named by astronomical convention for the instr

NEW YORK--Despite the rain and cold this past weekend, dozens of robots took the field to compete in the New York City FIRST Tech Challenge (FTC) regional championship at the Javitz Center in Manhattan. The tournament tested the skills and determinati

Male pregnancy occurs only in seahorses, pipefish and seadragons. The male protects and feeds developing offspring in its brood pouch. But new research shows that male pipefish selectively abort embryos from less attractive females.

Associate editor Larry Greenmeier covers the FIRST technology challenge held in New York City. High school students put their bot designs to the test and compete for a spot in the national competition held later this year in Atlanta.

In the mid-20th century the encyclopedic works of French mathematician Nicolas Bourbaki traced every mathematical concept back to the subject’s foundations in the theory of sets--the stuff of Venn diagrams--and changed the face of his field. Like many o

In the high-energy physics community, all eyes have been on Europe for some time, as the Large Hadron Collider , or LHC, has proceeded in fits and starts to become, in 2009, the most powerful atom smasher the world has ever seen. But as the LHC has tak

Forget banking and the automotive industry. Earth is the one system that is truly “too big to fail.” For centuries humans have used up the planet’s resources, saddled it with our waste and simply moved on when a wellspring dried up or the back forty
