Just like a lock can be picked, any biometric scanner can be fooled. Researchers have shown for years that the popular fingerprint sensors used to guard smartphones can be tricked sometimes, using a lifted print or a person’s digitized fingerprint data. But new findings from computer scientists at New York University’s Tandon School of Engineering could raise the stakes significantly.

Designed by Danny Hillis, the Clock is designed to run for ten millennia with minimal maintenance and interruption. The Clock is powered by mechanical energy harvested from sunlight as well as the people that visit it. The primary materials used in the Clock are marine grade 316 stainless steel, titanium and dry running ceramic ball bearings. The entire mechanism will be installed in an underground facility in west Texas.

 

In 02011, The American Astronomy Society published a paper co-written by Danny Hillis that describes how the Clock reckons time over its 10,000-year design lifetime.

What do scientists see when comparing our future climate with the past? In less than 200 years, humans have reversed a multimillion-year cooling trend, new research suggests.

If global warming continues unchecked, Earth in 2030 could resemble its former self from 3 million years ago, according to a study published Monday in the journal Proceedings of the National Academy of Sciences finds.
 
During that ancient time, known as the mid-Pliocene epoch, temperatures were higher by about 2 to 4 degrees Celsius (3.6 to 7.2 degrees Fahrenheit) and sea levels were higher by roughly 20 meters (almost 66 feet) than today, explained Kevin D. Burke, lead author of the study and a researcher and Ph.D. candidate at the Nelson Institute for Environmental Studies at the University of Wisconsin-Madison.

Over the past three decades of global warming, the oldest and thickest ice in the Arctic has declined by a stunning 95 percent, according the National Oceanic and Atmospheric Administration’s annual Arctic Report Card.

 

The finding suggests that the sea at the top of the world has already morphed into a new and very different state, with major implications not only for creatures such as walruses and polar bears but, in the long term, perhaps for the pace of global warming itself.
