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…)

Neue Rekorde bei globaler Klimaschutzaktion Earth Hour / 162 Länder und 7.000 Städte rufen zum Schutz des Planeten auf

Berlin – Von Thailand bis Tahiti, vom Vatikan bis Las Vegas und von der Internationalen Raumstation bis in den Sudan – am Samstag fand die achte WWF Earth Hour unter Rekordbeteiligung statt. Um ein Zeichen für den Schutz des Planeten zu setzen, schalteten jeweils um 20.30 Uhr Ortszeit Millionen Menschen und über 7.000 Städte in insgesamt 162 Ländern die Lichter aus. Während der „Stunde der Erde“ erlosch die Beleuchtung zahlreicher symbolträchtiger Bauwerke und Orte, darunter die Golden Gate Bridge in San Francisco, der Petersdom im Vatikan, der Las Vegas Strip, der Burj Khalifa in Dubai oder der Tokyo Tower in Japan. Höher als je zuvor fiel auch die Teilnahme in Deutschland aus – 160 Städte und Gemeinden folgten dem Aufruf des WWF. (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…)

“It‘s your privacy, stupid” – Erfahrungsbericht einer Kryptoparty

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…)

NASA Snow Mapper Reaps Big Benefits for California

Unprecedented snowpack maps from NASA’s prototype Airborne Snow Observatory mission helped water managers for 2.6 million residents of the San Francisco Bay Area achieve near-perfect water operations this summer, despite the driest year in California’s recorded history.

The high-resolution NASA snow maps of the Tuolumne River Basin in the Sierra Nevada helped optimize reservoir filling and hydroelectric generation at the Hetch Hetchy reservoir and its O’Shaughnessy Dam. This resulted in a full reservoir at the end of the snowmelt season, no water spillage, and generation of more than $3.9 million in hydropower. The NASA data helped optimize operations during the last two critical weeks of runoff. (more…)

SOI Collaborating With WHOI On Construction of World’s Most Advanced Deep-diving Robotic Vehicle

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…)

‘Heart of a Soldier’ author recalls how New Yorker article became prize-winning book

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…)
