Redefinition of the kilogram will not make the kilogram more precise, but it will make it more stable. A physical object can lose or gain atoms over time, or be destroyed, but constants remain the same. And a definition based on constants would, at least in theory, allow the exact kilogram measure to be available …
A new analysis of an ape that lived 12.5 million years ago suggests it is a type of gorilla. If that’s true, it means gorillas evolved much earlier than thought, and also pushes back the time when humans split from chimps by about 2 million years. David Begun of the University of Toronto in Canada …
China’s first AP1000 reactor, Sanmen 1, is expected to begin commercial operation in September 2016, while governmental permission is expected for work to start on the first Chinese-designed CAP1400 by the end of this year Sanmen 1, in Zhejiang province, is one of four Westinghouse-designed AP1000s currently under construction in China. Work officially began on …
New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time. They …
China is ready to launch its first domestically built aircraft carrier, known as the Type 001A, on Dec. 26 to mark the 122th birthday of Mao Zedong, according to Hong Kong newspaper Ming Pao. President Xi Jinping reportedly visited the Dalian Shipyard to inspect the progress of work on the carrier in August. Previous reports …

Intelsat the world’s leading provider of satellite services, and Kymeta Corporation, the leading developer of metamaterials-based antenna technology, announced an agreement to design and produce innovative, flat, electronically steerable, Ku-band mTenna™ satellite antenna solutions that are optimized for the Intelsat EpicNG high throughput satellite (HTS) platform. The first Intelsat EpicNG satellite is expected to launch …
Physicists have found a radical new way confine electromagnetic energy without it leaking away, akin to throwing a pebble into a pond with no splash The theory could have broad ranging applications from explaining dark matter to combating energy losses in future technologies. However, it appears to contradict a fundamental tenet of electrodynamics, that accelerated …
A virus found in sewage has spawned a unique drug that targets plaques implicated in a host of brain-crippling diseases, including Alzheimer’s disease, Parkinson’s disease and Creutzfeldt-Jakob disease (CJD). Results from tests of the drug, announced this week, show that it breaks up plaques in mice affected with Alzheimer’s disease or Parkinson’s disease, and improves …
