10 Tips Jadi Teman Bicara yang Menyenangkan

Menjadi teman berbincang yang menyenangkan bisa dibilang susah-susah gampang. Apalagi dengan orang yang baru dikenal. Itu bukti bahwa tidak semua orang betul-betul menguasainya,

Fukushima's Spreading Impact

The nuclear accident at Japan's troubled Fukushima Daiichi reactor complex appears to be heading from very bad to critical in the wake of the third explosion in four days, a fire in one of the plant's spent fuel ponds, and radiation readings spiking to deadly levels within the plant.

Internet Activists Mobilize for Japan

Just a few hours after Japan was devastated by an earthquake and tsunami early on Friday morning, people mobilized online to help.

Low-Power Memory from Nanotubes

A new type of nonvolatile memory based on carbon nanotubes has dramatically lower power requirements than current technology. It uses the nanotubes to read and write data to small islands of phase-change materials, which store information. With further development, the new technology could extend battery life in mobile devices and also make desktop computers more efficient.

How Japan's Earthquake and Tsunami Warning Systems Work

The earthquake that struck Japan early this morning was the worst seen in that country for over 300 years (with a local magnitude of 8.9). Hundreds have been killed and injured so far, but the loss of life was likely limited by two vital early warning technologies: a new earthquake alert system, and ocean-based tsunami warning system.

80 Seconds of Warning for Tokyo

Residents of Tokyo likely had about 80 seconds of warning before a devastating quake rumbled through the city after striking 373 kilometers away, off Japan's northeast coast, thanks to a new early warning system. But tsunami alerts take longer to generate, giving just minutes of warning before the waves first struck the coast—a reflection of the differing technologies needed to detect earthquakes and calculate their impacts, researchers say.
