The long view
China exerting “sharp power” influence on American institutions
China is penetrating American institutions in ways that are coercive and corrupt, while the United States has not fully grasped the gravity of the situation, a Hoover Institution expert says. “An ultimate ambition for global hegemony” is driving China’s multifront efforts to manipulate US state and local governments, universities, think tanks, media, corporations, and the Chinese American community, said Larry Diamond, a senior fellow at Hoover.
Airport security screening without queues
Researchers have invented a device that could be developed into ultra-sensitive cameras for security screening which would not require people to queue at airports. Other applications could include smaller and safer sensors for driverless vehicles.
Significance vulnerabilities discovered in high-performance computer chips
Researchers have uncovered significant and previously unknown vulnerabilities in high-performance computer chips that could lead to failures in modern electronics. The researchers found they could damage the on-chip communications system and shorten the lifetime of the whole computer chip significantly by deliberately adding malicious workload.
Friendly electromagnetic pulse improves survival for electronics
An electromagnetic pulse, or EMP, emitted by a nuclear weapon exploded high above the United States could disable the electronic circuits of many devices vital to military defense and modern living. These could include complicated weapon systems as well as phones, laptops, credit cards and car computers. Also, in trouble might be home appliances, gas station pumps and bank accounts. Military equipment – and some civilian equipment, too — are designed to be immune to various levels of EMP, and the validity of these designs has been tested and improved by a “friendly” EMP generator installed in a recently renovated facility at Sandia National Laboratories.
Foldable drone flies through narrow passages in rescue missions
Researchers have developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
National Climate Assessment: Will U.S. water problems worsen?
Upmanu Lall is director of the Columbia Water Center, chair of Earth and Environmental Engineering, and the lead author of the chapter on water resources in the latest U.S. National Climate Assessment. The report, issued two weeks ago, paints a troubling picture of the nation’s climate future, including projected droughts and extreme precipitation events that could worsen already existing problems with U.S. water supplies and infrastructure. Lall discusses the climate change-driven water challenges the U.S. faces, and ideas for how the nation can respond.
