‘We didn’t give Turkey the green light’ – Pompeo defends Syria withdrawal

World
By Alix Culbertson and Chris Robertson, news reporters US Secretary of State Mike Pompeo has defended Donald Trump's withdrawal of troops in Syria, saying the president did not give Turkey the "green light" to invade the country.Speaking to PBS Newshour, Mr Pompeo said that during the phone call with Turkish President Recep Tayyip Erdogan "it became very clear that there were American soldiers that were going to be at risk and the President made a decision to put them in a place where they were out of harm's way. That's what we've done". He also added that he feels that Turkey has a "legitimate security concern" and waved off claims from Republican Senator Lindsay Graham that the attack could lead to a reemergence of IS. The land assau...
New quantum technology enables light manipulation at greater scales

New quantum technology enables light manipulation at greater scales

Science
Sept. 27 (UPI) -- To develop the next generation of quantum technologies, scientists need to find new ways to manipulate light. In a new paper, published Friday in the journal NPJ Quantum Information, an international group of scientists claim to have done precisely that. According to lead author Omar Magaña-Loaiza, an assistant professor in the department of physics and astronomy at the Louisiana State University, the breakthrough could inspire quantum technologies with applications in imaging, computation, communication and cryptography. The new method for controlling light could also aid the field of metrology, the science of measurement. "If we're able to control photon fluctuations and associated noise," Magaña-Loaiza said in a news release. "Then, we can make more precise measurem

Thermoelectric device harnesses cold of space to power LED light at night

Science
Sept. 13 (UPI) -- Engineers have developed a thermoelectric device that works in the dark of night, harnessing the cold of space and turning it into electricity to power an LED light. The affordable technology works without any heat inputs. "Remarkably, the device is able to generate electricity at night, when solar cells don't work," Aaswath Raman, an assistant professor of materials science and engineering at the University of California, Los Angeles, said in a news release. "Beyond lighting, we believe this could be a broadly enabling approach to power generation suitable for remote locations, and anywhere where power generation at night is needed." Batteries can be installed on solar cells to store energy harvested during the day for use at night, but the add-on is costly. Otherwise,...

Pound rallies while CBI welcomes ‘chink of light’ over no-deal Brexit

Business
By John-Paul Ford Rojas, business reporter The pound has enjoyed its best two-day rally in ten months as investors and business groups welcome the vote by MPs to try and stop a no-deal Brexit.The CBI described the cross-party alliance's victory over Boris Johnson as a "small chink of light for business" but warned that uncertainty would continue to hold back investment. Carolyn Fairbairn, director-general of the lobby group, called for a "spirit of compromise" in Westminster to avoid an economic crisis.Her reaction came as the pound added to gains seen on Wednesday as the House of Commons backed a law to try to avoid a no-deal scenario, reaching its highest level since the end of July.Ms Fairbairn said: "From the political turmoil a sma...
