Ultracold atoms are still too hot. This may seem a ridiculous claim—after
all, the low-temperature exploits of the purveyors of quantum gases are
notorious. Laser cooling can flash-freeze atoms to temperatures in the micro-
and nanokelvin...

In the 2,000 or so years since the Roman Empire employed a naturally
occurring form of cement to build a vast system of concrete aqueducts and other
large edifices, researchers have analyzed the molecular structure of natural
materials and...

Carbon-rich meteorites that crash to Earth carry a wealth of information from
far-flung regions of outer space. Now, it seems that some extraterrestrial
baggage survives the long journey intact. A new study shows that carbon
molecules known...

When a noise occurs,
such as a car honking or a person laughing, sound vibrations entering the ear
first bounce against the eardrum, causing it to vibrate. This, in turn, causes
three bones in the middle ear to vibrate, amplifying the sound....

Nearly a decade ago, now-Nobel laureates Craig Mello and Andrew Fire
discovered that they could insert short RNA molecules into worms and shut down
specific genes. Today, scientists routinely use this powerful method, termed RNA...

Cornell researchers have answered a fundamental question about how two
strands of DNA, known as a double helix, separate to start a process called
replication, in which genes copy themselves. The research, published in the
current issue of...
