Berkeley Lab researchers help scientists determine the radiation risk of exploring an underwater aircraft carrier.
About 42 miles southwest of San Francisco and 2,600 feet underwater sits the U.S.S. Independence, a bombed-out relic from World War II. The aircraft carrier was a target ship in atomic weapon tests at Bikini Atoll in the Marshall Islands after the war. Then, in 1951, it was loaded up with 55-gallon drums of low-level radioactive waste and scuttled just south of the Farallon National Wildlife Refuge off the California coast.(more…)
NASA is partnering with the California Department of Water Resources (DWR) to develop and apply new technology and products to better manage and monitor the state’s water resources and respond to its ongoing drought.
NASA scientists, DWR water managers, university researchers and other state resource management agencies will collaborate to apply advanced remote sensing and improved forecast modeling to better assess water resources, monitor drought conditions and water supplies, plan for drought response and mitigation, and measure drought impacts.

Ultra-high definition 4K movie or 40,000 songs from the Cloud could be downloaded in a few seconds
SAN FRANCISCO – 13 Feb 2014: IBM today announced that it has achieved a new technological advancement that will helpimprove Internet speeds to 200 – 400 Gigabits per second (Gb/s) at extremely low power.
The speed boost is based on a device that can be used to improve transferring Big Data between clouds and data centers four times faster than current technology. At this speed 160 Gigabytes, the equivalent of a two-hour, 4K ultra-high definition movie or 40,000 songs, could be downloaded in only a few seconds. The device was presented at the International Solid-State Circuits Conference (ISSCC) in San Francisco. (more…)
Über ein halbes Jahr ist es her, dass Edward Snowden mit seinen Enthüllungen eine globale Überwachungs- und Spionageaffäre ausgelöst hat, von der nicht nur das Handy von Kanzlerin Angela Merkel, sondern auch die private Kommunikation von Millionen Deutschen betroffen ist. Im Selbstversuch hat die politik-digital.de-Redaktion das Verschlüsseln geübt und eine Kryptoparty veranstaltet. Das Ergebnis: Es hat sogar Spaß gemacht. Ein Erfahrungsbericht.
Seit Monaten schon fordern Datenschützer, Internetaktivisten, Programmierer und Hacker uns auf, unsere Daten und Kommunikationswege zu schützen. In der Redaktion von politik-digital.de kennen wir die Argumente für und gegen Verschlüsselung gut. Mit der praktischen Umsetzung befasst haben wir uns aber bisher kaum. Währenddessen kommen immer weitere Details über die Machenschaften der Geheimdienste ans Licht, und die Regierungen zeigen sich weiterhin wenig beeindruckt von der Empörung in breiten Teilen der Gesellschaft. Bequemlichkeit und Zeitmangel können als Ausreden also nicht mehr gelten, und so haben wir beschlossen, dass es höchste Zeit ist, uns kryptografische Fähigkeiten anzueignen. (more…)
Schmidt Ocean Institute (SOI) has begun working with the Deep Submergence Laboratory at the Woods Hole Oceanographic Institution (WHOI) to design and build the world’s most advanced robotic undersea research vehicle for use on SOI’s ship Falkor. The new vehicle will be capable of operating in the deepest known trenches on the planet, including the nearly 11,000-meter-deep Challenger Deep in the Mariana Trench. The design will capitalize on lessons learned from past WHOI vehicle designs, as well as advanced technologies developed for DEEPSEA CHALLENGER, the submersible and science platform that explorer and director James Cameron piloted to Challenger Deep in 2012 and donated to WHOI in 2013.
On Sunday, December 8th, Victor Zykov, SOI’s director of research, will publicly discuss the project for the first time at a University-National Oceanographic Laboratory System’s (UNOLS) Deep Submergence Science Committee meeting in San Francisco. (more…)
James B. Stewart, a Pulitzer Prize-winning author and reporter for the New Yorker, talked on campus on Oct. 4 about the inspiration for and process behind “Heart of a Soldier,” his 2002 book about Rick Rescorla, a security guard at the World Trade Center who lost his life on 9/11. Stewart’s talk was sponsored by the Poynter Fellowship in Journalism at Yale.
Tasked with reporting on the impact of the World Trade Center attacks on business, Stewart discovered — by chance — the heroic tale of Rick Rescorla and realized that his was a story worth telling. “If you have a character, anything becomes a story,” Stewart explained. (more…)
New findings overturn understanding of light-dependent environmental oxidants
Breathing oxygen… can be hazardous to your health?
Indeed, our bodies aren’t perfect. They make mistakes, among them producing toxic chemicals, called oxidants, in cells. We fight these oxidants naturally, and by eating foods rich in antioxidants such as blueberries and dark chocolate.
All forms of life that breathe oxygen—even ones that can’t be seen with the naked eye, such as bacteria—must fight oxidants to live. (more…)
Professor, author Robertson discusses innovation evolution at Lego
When you hear Lego, if all you think about are shiny, plastic bricks and toys, think again. From a toy concept brought to life by a carpenter to tales of failed innovation truths that mirrored a Greek tragedy, the Lego story is about innovation and evolution, David Robertson told attendees at last week’s Chaplin Tyler Executive Leadership series lecture.
Robertson, professor of practice at the Wharton School at the University of Pennsylvania, presented “Rebuilding Lego” to 80 students, faculty, staff and community members on the University of Delaware’s Newark campus. (more…)
