Scientists pave way for carbon-based computers

Scientists pave way for carbon-based computers

Science
Sept. 25 (UPI) -- Today's transistors, the building blocks of modern electronics, are mostly composed of silicon, but scientists theorize carbon-based transistors eventually could power faster, more efficient computers. Testing that theory has proven difficult, but thanks to a recent breakthrough, detailed Friday in the journal Science, researchers now are closer to finally building a transistor entirely from carbon. Advertisement A team of chemists and physicists at the University of California-Berkeley succeeded in building a metallic wire out of carbon. "Our breakthrough was to make metallic nanoribbons," study co-author Michael Crommie, professor of physics at Berkeley, told UPI in an email. Previously, scientists theorized that graphene nanoribbons could only form insulators or semi...

Weird weather: Can computers solve UK puzzle?

Science
A top climate scientist has called for more investment in climate computing to explain the UK’s recent topsy turvy weather.Prof Tim Palmer from Oxford University said there were still too many unknowns in climate forecasting.And in the month the SpaceX launch grabbed headlines, he said just one of the firm's billions could transform climate modelling.Short-term weather forecasting is generally very accurate.And long-term trends in rising temperatures aren’t in doubt.But Prof Palmer says many puzzles remain unsolved: take the recent weird weather in the UK, with the wettest February on record followed by the sunniest Spring. Forecasters set for 'billion pound' supercomputer May was sunniest UK month on record Weather somersaultMet...

General Election 2019: How computers wrote BBC election result stories

Technology
For the first time, BBC News published a news story for every constituency that declared election results overnight - all written by a computer.It was the BBC's biggest test of machine-generated journalism so far.Each of nearly 700 articles - most in English but 40 of them in Welsh - was checked by a human editor before publication.The head of the project said the tech was designed to enhance the service provided rather than to replace humans."This is about doing journalism that we cannot do with human beings at the moment," said Robert McKenzie, editor of BBC News Labs."Using machine assistance, we generated a story for every single constituency that declared last night with the exception of the one that hasn't finished counting...

Trump ‘orders cyber attack’ on Iranian military computers

Technology
By Lucia Binding, news reporter The US launched a cyber strike against Iranian military computer systems earlier this week as Donald Trump pulled out of airstrikes, officials have reportedly confirmed.The attacks were conducted with approval from the president on Thursday in response to Iran's downing of an American surveillance drone, two US officials told The Associated Press. A third official confirmed the broad outlines of the strike and all spoke on condition of anonymity because they were not authorised to talk publicly about the operation.

Humans can be tricked just like computers

Humans can be tricked just like computers

Science
March 22 (UPI) -- Using the same visual tricks that trip up computers, researchers at Johns Hopkins University have managed to get humans to think like CPUs. "Most of the time, research in our field is about getting computers to think like people," Chaz Firestone, an assistant professor of psychological and brain sciences at Johns Hopkins, said in a news release. "Our project does the opposite -- we're asking whether people can think like computers." Computers do a few things much better than humans. They can easily solve complex math problems and remember vast quantities of information. But some tasks that are quite easy for humans, recognizing everyday objects like a dog, bus or a table and chairs, are exceedingly difficult for even the most powerful computers. However, computers are g...
