Using laser tweezers, chemists nudged two atoms to bond

Using laser tweezers, chemists nudged two atoms to bond

Posted by | Apr 13, 2018 | , , |

It’s the first time chemists have manipulated two atoms to create a compound. For the first time, researchers have played matchmaker between two specific atoms, joining them together to form a molecule. Typically, chemists make molecules by mixing up many constituent atoms, some of which stick to each other to form the desired compounds. In the new, supercontrolled chemical reaction, researchers trapped a single sodium atom in one optical tweezer — a device that snares small particles in a laser beam — and a cesium atom in another tweezer. Both atoms were cooled to less than one ten-thousandth of...

German van attack: ‘Suspect had mental health problems’

German van attack: ‘Suspect had mental health problems’

Posted by | Apr 9, 2018 | , |

The man suspected of carrying out a van attack in Muenster was a lone German who suffered mental health problems, the state interior minister has said. Authorities have searched four homes associated with the suspect, and said they have found “no clues” pointing to an extremist or political motive. Two people were killed when a van was driven into a restaurant terrace area of the west German city on Saturday. The 48-year-old driver shot and killed himself after hitting diners. He has been identified in German media as Jens R – prosecutors say he was known to police. In...

Inside the White House Bible Study group

Posted by | Apr 8, 2018 | , , |

For the first time in at least 100 years, the US Cabinet has a bible study group. What do they learn? What does Donald Trump make of it? And why aren’t women allowed to teach? Every Wednesday, some of the world’s most powerful people meet in a conference room in Washington DC to learn about God. The location can’t be revealed – the Secret Service won’t allow it – but the members can. Vice-President Mike Pence. Secretary of State Mike Pompeo. Education Secretary Betsy DeVos. Energy Secretary Rick Perry. Attorney General Jeff Sessions. The list goes on. In total,...

Apple iOS 11.3.1 Release: It’s The Big One

Apple iOS 11.3.1 Release: It’s The Big One

Posted by | Apr 6, 2018 | |

This was not meant to happen. iOS 11.3 had the eyes of the world on it and Apple AAPL +0.73% seemed so confident the company immediately moved onto testing iOS 11.4, which is not due for release for several months. Instead, a litany of bugs (a significant number are serious) means the urgent release of iOS 11.3.1 is now unavoidable and essential… Tech writer Bradley Chambers perhaps summed it up best when commenting on the iOS 11.3 bug which broke Apple’s MDM (Mobile Device Management) protocol leaving participating companies and institutions unable to remotely manage and update employees’ iPhones...

Why AI isn’t going to solve Facebook’s fake news problem

Why AI isn’t going to solve Facebook’s fake news problem

Posted by | Apr 6, 2018 | , , |

Moderation will always be a problem on a platform this huge. Facebook has a lot of problems right now, but one that’s definitely not going away any time soon is fake news. As the company’s user base has grown to include more than a quarter of the world’s population, it has (understandably) struggled to control what they all post and share. For Facebook, unwanted content can be anything from mild nudity to serious violence, but what’s proved to be most sensitive and damaging for the company is hoaxes and misinformation — especially when it has a political bent. So...
