For the first time, researchers have managed to capture images of individual potassium atoms distributed on an optical lattice, providing them with a unique opportunity to see how they interact with one another.
While capturing these images is a feat in itself, the technique could help researchers to better understand the conditions needed for individual atoms to come together and form exotic states of matter like superfluids and superconductors.
“Learning from this atomic model, we can understand what’s really going on in these superconductors, and what one should do to make higher-temperature superconductors, approaching hopefully room temperature,” team member Martin Zwierlein from MIT said in a statement.
To capture the images, the team took potassium gas, and cooled it only a few nanokelvins – just above absolute zero. To put that into perspective, 1 nanokelvin is -273 degrees Celsius (-460 degrees Fahrenheit).
At this extremely cold temperature, the potassium atoms slow to a crawl, which allowed the team to trap some of them inside a two-dimensional optical lattice – a complex series of overlapping lasers that can trap individual atoms inside different intensity waves.

Do you remember the feeling of enjoying your childhood while you were on a bicycle? The wind rustling through your hair, the birds chirping during those warm summer days. Ah, those were good times, and back then, there wasn’t too much traffic on the road, either. Making it a perfect setting for you to cycle around. The thing is, the older bicycles still came with a bell that you could …
What do you do with very large and controversial statues no one wants? What’s the dilemma faced by Baltimore Mayor Stephanie Rawlings-Blake following a city commission recommendation to remove two statues — one of Confederate generals Robert E. Lee and Thomas “Stonewall” Jackson, and one of Supreme Court Chief Justice Roger Taney, who authored the infamous Dred Scott decision — from city land.
“She wants to find an appropriate place for those monuments, if she decides to go ahead and remove them,” said Rawlings-Blake’s spokesman, Anthony McCarthy. “It hasn’t been as easy, to be honest, as we thought.”
In fact, the city has been quietly contacting “Confederate groups” to ask if they would like to buy the statues, the Wall Street Journal reports, but so far the organizations have balked either at the cost or the idea of helping to remove the memorials from public space. The commission recommended transferring the statues to a national park such as a Civil War battlefield, but it turns out parks aren’t allowed to accept the statues unless they were previously “removed from the park and are necessary to achieve the park purpose or authorized legislation.”
In the meantime, Rawlings-Blake has ordered new signage for both statues, as well as two other Confederate monuments the commission decided to keep, to explain their historical context.Read more
Birtherism is a smear against President Obama that was started by Hillary Clinton’s 2008 campaign, Donald Trump’s campaign manager, Kellyanne Conway, insisted in an interview with Chuck Todd on CBS’ Face the Nation on Sunday, citing several Clinton staffers who reportedly entertained or promoted the conspiracy theory.
Conway was speaking in response to Trump’s recent concession that Obama was born in the United States. “This started with Hillary Clinton’s campaign, No. 1,” she said. “No. 2, it was Donald Trump who put the issue to rest when he got President Obama to release his birth certificate years later. And, No. 3, he said that ‘President Obama was born in this country, period.'”
Todd wasn’t satisfied, however, and pressed Conway on why “two wrongs make a right in this case,” arguing that birther allegations were a major feature of Trump’s public persona for years and highlighting the Trump campaign’s recent labeling of birtherism as a “smear.”
“The only people still obsessed about this,” Conway retorted, is the media.Read more
The tablet industry might be going downhill, but this does not mean that it is about to close its shutters anything soon. Nay! In fact, there is still a sizeable market out there where tablets are concerned, with Apple’s iPad range taking a huge chunk of it, while Android has its fair share of devices from notable manufacturers as well as lesser known factory names. Mattel, a name that is …
