Arctic sea ice shrinks to second lowest level

WASHINGTON (AP) — Arctic sea ice melted this summer to the second lowest level since record-keeping began more than 50 years ago, scientists reported Thursday, mostly blaming global warming. “This is not a random event,” said oceanographer James Overland of the U.S. National Oceanic and Atmospheric Administration. “It’s a long-term change in Arctic climate.” The […]

Researchers pay for Alaska sea lion intrusion

ANCHORAGE, Alaska (AP) — A science consortium has agreed to a civil penalty of $9,000 for intruding into Alaska waters that were declared off-limits to protect endangered Steller sea lions. But an attorney for the group, which included participants from Vanderbilt, Rutgers and Pittsburgh universities, took strong exception to a federal agency linking the scientists […]

Disasters in US: An extreme and exhausting year

A billion-dollar blizzard. And now, unusual hurricane-caused flooding in Vermont. If what’s falling from the sky isn’t enough, the ground shook in places that normally seem stable: Colorado and […]

NASA launching twin moon probes to measure gravity

CAPE CANAVERAL, Fla. (AP) — Four decades after landing men on the moon, NASA is returning to Earth’s orbiting companion, this time with a set of robotic twins that will measure lunar gravity while chasing one another in circles. By creating the most precise lunar gravity map ever, scientists hope to figure out what’s beneath […]

What Is Biodiesel?

Biodiesel is a fuel made from vegetable oils. Rapeseed and soybean oils are the most commonly used, although other vegetables oils such as mustard, palm oil, hemp and jatropha have been tried and seem to show a lot of potential. These are listed or called Virgin Oil Feedstock. We also have waste vegetable oils that […]

It’s alive! Space station’s humanoid robot awake

CAPE CANAVERAL, Fla. (AP) — NASA’s humanoid robot has finally awakened in space. Ground controllers turned Robonaut on Monday for the first time since it was delivered to the International Space Station in February. The test involved sending power to all of Robonaut’s systems. The robot was not commanded to move; that will happen next […]

Fiber Optics

Fibre optics has been fabricated from materials that transmit light and are made from a bundle of very thin glass or plastic fibres enclosed in a tube. One end is at a source of light and the other end is a camera lens, used to channel light and images around the bends and corners. There […]
