Using data mining to make sense of climate change

Added: 19.01.2018 2:02 | 0 views | 0 comments

Experts have developed a new way of mining data from climate data sets that is more self-contained than traditional tools. The methodology brings out commonalities of data sets without as much expertise from the user, allowing scientists to trust the data and get more robust -- and transparent -- results.

Method uses DNA, nanoparticles and lithography to make optically active structures

Added: 19.01.2018 2:02 | 0 views | 0 comments

Researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices -- news to make the ears of Star Trek's Spock perk up. Using DNA as a key tool, the scientists took gold nanoparticles of different sizes and shapes and arranged them in two and three dimensions to form optically active superlattices. The structures could be programmed to exhibit almost any color across the visible spectrum.

Women have many options for oral contraceptives that are safe, effective and reversible, but despite decades of research, men have none. Now, scientists report a rat study that shows they finally have a good lead for a male birth control pill. It's based on ouabain, a plant extract that African warriors and hunters traditionally used as a heart-stopping poison on their arrows.

Donald Trump listens to EPA Administrator Scott Pruitt after announcing his decision that the United States will withdraw from the Paris Climate Agreement, in the Rose Garden of the White House in Washington, U.S., June 1, 2017. The debate is how do we know what the ideal surface temperature is in 2100? Shifting the ‘debate’ toward ‘the ideal surface temperature’ achieves that goal by creating the perception that we don’t know what temperature we should aim for.
