Digital Dandelions

What looks like the head of a digital dandelion is a map of the Internet generated by new algorithms from computer scientists at UC San Diego. This map features Internet nodes – the red dots – and linkages – the green ...

Professor looks for life in and under antarctic ice

Antarctica is home to the largest body of ice on Earth. Prior to approximately 10 years ago, no one thought that life could exist beneath the Antarctic ice sheets, which can be more than two miles thick in places, because ...

A genetic trigger for the Cambrian explosion unraveled?

A team of scientists led by young Croatian evolutionary geneticist Tomislav Domazet-Lošo from Ruder Boškovic Institute (RBI) in Zagreb, Croatia, developed a novel methodological approach in evolutionary studies. Using the ...

Dark Pit on Mars' Arsia Mons, with Sunlit Wall

The High Resolution Imaging Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter has confirmed that a dark pit seen on Mars in an earlier HiRISE image really is a vertical shaft that cuts through lava flow on ...

Ancient yucca chaws yield ancient DNA

In a groundbreaking study, two Harvard scientists have for the first time extracted human DNA from ancient artifacts. The work potentially opens up a new universe of sources for ancient genetic material, which is used to ...

Free Electron Laser Laboratory Funding Threatened

Federal funding for an experimental laser program at Duke and other major U.S. universities has been marked for elimination by the Department of Defense despite support from North Carolina members of Congress.

NIST Measures Challenges for Wireless in Factories

Factories have much to gain from wireless technology, such as robot control, RFID tag monitoring, and local-area network (LAN) communications. Wireless systems can cost less and offer more flexibility than cabled systems. ...

Longer is Better for Nanotube Optical Properties

If you want to exploit the ability of single-walled carbon nanotubes (SWCNTs) to absorb, fluoresce and scatter light, take the advice of a sandlot quarterback and “go long.”

Chandra Peers at Cosmic Super Bubbles

Using the Chandra X-ray Observatory, astronomers explored a particular region of clouds and gas where stars are forming in one of the Milky Way's closest galactic neighbors.
