Can a lie-in make you healthier? 睡懒觉能让你更健康？

link

Every morning, my alarm goes off, I wake from my slumber and hit the snooze button. Then I crawl back under the duvet to grab a few more minutes of shut-eye. “Tonight I’ll go to bed early,” I tell myself. But, evening comes and I get a second wind, completely forgetting about my early night.

Why am I finding it so difficult to get a good night’s sleep? And is it a problem?

The amount we sleep has declined over the years and insomnia is on the rise. Modern technology is often blamed. The light from our smartphone affects levels of melatonin – the sleep-inducing hormone - keeping us wide awake into the early hours.

Cracked iPhone: Should you be worried?

link

The US government’s declaration that it has “successfully accessed the data stored on [San Bernardino gunman] Farook’s iPhone and therefore no longer requires” assistance from Apple, ends a six week-long legal clash between the tech firm and the FBI.

But it leaves the issue at the heart of the dispute unresolved: could the FBI have forced Apple to help it unlock the device?

It is unlikely that this will be the last time a law enforcement agency tries to compel a tech company to help bypass security measures.

Is there any way to find out how Farook’s iPhone was cracked?

At this point, there is nothing to compel the FBI to reveal how it was done, although Apple is likely to be pressing hard to find out.

The tech firm’s lawyers have already said they would want details of the technique to be made public if evidence from the cracked iPhone is later used at trial.

But it could remain secret. There is scope within US law for the authorities to withhold the source of information if it was supplied to them on a confidential basis, and to protect sensitive intelligence-gathering methodologies.

Volkswagen recall is third electric car call-back in a month

link

Volkswagen has recalled thousands of its e-Golf cars in the US citing a problem that could cause their motors to switch off while in use.

The NHTSA said that during cold temperatures, a part used in the Nissan Leaf’s electronic brake booster could freeze, requiring more effort to bring the vehicles to a halt.

The French firm said on 24 March that it needed to check the position of th**e Zoe’s** brake fluid hose to ensure it would not be damaged by coming into contact with a part designed to protect the vehicle’s front wheel arch.
