Study finds blue light filters like ‘Night Light’ might actually keep you awake – 9to5Google
A couple of years ago, science was convinced that the blue light coming from our screens was not only harmful, but could keep us awake at night, too. The countermeasure to that was blue light filters that were widely adopted, but now it seems those filters are just as bad.
Nomad case for Pixel 3
The University of Manchester published a study (via the Guardian) that found blue light filters may actually trick our brains into thinking it’s daytime, exactly the thing they were designed to avoid.
Those blue light filters, like the Pixel’s “Night Light,” were designed to reduce a protein in your eye called melanopsin. That protein responds to the intensity of light, especially when that light is of a shorter wavelength, i.e. blue lights. When the screen is tinted yellow, the blue portion of RGB lights is lessened considerably.
The study found that warm, yellow light tricks your brain into thinking that it’s actually daytime. The warmer colors tell your body clock that it’s sunrise or sunset, in either case telling your body that it’s not quite time to go to sleep yet.
We show the common view that blue light has the strongest effect on the clock is misguided; in fact, the blue colors that are associated with twilight have a weaker effect than white or yellow light of equivalent brightness.
We argue that this is not the best approach, since the changes in color may oppose any benefits obtained from reducing the brightness signals detected by melanopsin. Our findings suggest that using dim, cooler lights in the evening and bright warmer lights in the day may be more beneficial.
At the end of the day (literally), it’s probably just better to stop using your phone instead of using tricks like this. You’ll sleep better.

The Trump administration is halting shipments from Intel and other Huawei suppliers in the final days of the current presidency.
Reuters reports that the administration has notified suppliers it’s revoking licenses that allow them to sell to the Chinese company. The administration also plans to reject other applications to supply to Huawei.
This latest action, which is likely U.S. President Donald Trump’s final blow to the Chinese company, builds on the administration’s efforts to weaken Huawei, which it sees as a national security threat.
Emails seen by Reuters reveal that the Commerce Department issued “intents to deny a significant number of license requests for exports to Huawei and a revocation of at least one previously issued license.”
Sources have said that eight licenses have been revoked from four companies. The department hasn’t commented on the news, but has said it will apply licensing policies in a way that “protects U.S. national security and foreign policy interests.”
Back in May 2019, the Trump administration put Huawei on an entity list that restricted suppliers from selling U.S. technology to it.
It’s worth noting that during his term, Trump has targeted Huawei in other ways as well. Huawei CFO Meng Wanzhou was arrested in Vancouver in 2018 on a U.S. warrant for violating sanctions in Iran. Meng’s extradition proceedings are still on-going.

Carl Pei to announce his new brand next week and he's also giving away 10 MacBook Air computers – gizmochina
Former OnePlus co-founder, Carl Pei, announced his exit from the company last October to start his own venture. In December, he revealed that his new startup has raised $7 million but revealed little details about the business. If you are curious just as we are, you should look forward to next week.
Today, Carl Pei took to Twitter to announce that the audio brand will be unveiled next week on January 27th. While that is exciting news, the founder will also be giving away 10 units of the new Apple M1-powered Macbook Air.
We’ll announce our new brand on the 27th and feeling grateful for all the support we’ve gotten thus far. Received M1 #MacBook Air for the team, and thought of doing a #giveaway for our community.

The giveaway is open to everyone from across the globe and winners will be selected on January 31.
There is little we know about Carl Pei’s new company other than that it will deal in audio-related products, though that may change later in the future as companies are known to expand their portfolio as they grow bigger.
The money raised for the startup last month was raised from family and friends that include notable names such as Casey Nesitat, Kevin Lin who co-founded Twitch, Tony Fadell who invented the iPod, Steve Huffman of Reddit, and Josh Buckley who is the CEO of Product Hunt.
