Palau plans sunscreen ban to save coral

A spokesman for President Tommy Remengesau said there was scientific evidence that the chemicals found in most sunscreens are toxic to corals, even in minute doses.

He said Palau’s dive sites typically hosted about four boats an hour packed with tourists, leading to concerns a build-up of chemicals could see the reefs reach tipping point.

“On any given day that equates to gallons of sunscreen going into the ocean in Palau’s famous dive spots and snorkelling places,” he told AFP.

“We’re just looking at what we can do to prevent pollution getting into the environment.”

The government has passed a law banning “-toxic” sunscreen from January 1, 2020.

Anyone importing or selling banned sunscreen from that date faces a $1,000 fine, while tourists who bring it into the country will have it confiscated.

“The power to confiscate sunscreens should be enough to deter their non-commercial use, and these provisions walk a smart balance between educating tourists and scaring them away,” Remengesau told parliament after the bill passed last week.

Environmental pioneer

The US state of Hawaii announced a ban on reef toxic sunscreens in May this year, but it does not come into force until 2021, a year after Palau’s.

The Palau ban relates to sunscreens containing chemicals including oxybenzone, octocrylene and parabens, which covers most major brands.

Palau has long been a pioneer in marine protection, introducing the world’s first shark sanctuary in 2009, in a move that has been widely imitated.

It has also banned commercial fishing from its waters and last year introduced the “Palau Pledge” requiring international visitors to sign a promise stamped into their passport that they will respect the environment.

Craig Downs, executive director at the Haereticus Environmental Laboratory in Hawaii, said other nations would be watching Palau’s move closely.

“It’s the first country to ban these chemicals from tourism. I think it’s great, they’re being proactive,” he said.

“They don’t want to be like Thailand, the Philippines and Indonesia, where they’ve had to shut down beaches. The coral reefs around those beaches have died.”

Downs said there were numerous scientific papers pointing to a link between sunscreen chemicals and .

“What we’re saying is that where there are lots of tourists getting in the water, sunscreen pollution can have a detrimental effect on nearby coral reefs, as far as five kilometres (3.1 miles) away,” he said.

Downs called on manufacturers to “step up and innovate”, saying the chemicals used for UV protection had been largely unchanged for 50 years.

He said there were some sunscreens containing zinc oxide and titanium dioxide that were not reef toxic but added: “The other alternative we’ve been pushing is sunwear—cover up, wear a sunshirt.”

FlexPai is the world’s first phone with fully foldable screen: 4″ 2 sided phone or 7.8″ tablet

The first foldable phone is a reality – the FlexPai. Well, it’s actually a tablet as unfolded it boasts a 7.8” screen (4:3 aspect ratio). Folded, that drops to a more manageable 4”. And get this, this device is the first to use the 7nm Snapdragon 8150!

Back to the screen, it’s an AMOLED that folds down the middle. The software (dubbed Water OS) switches to using only half of the screen, displaying a wallpaper on the other half.

You get to choose which half you use, though, one has slightly more screen, the other is next to the dual camera, which can be used for selfies and video calls in this configuration. It’s a 16+20MP camera, by the way, the second camera module has a telephoto lens.

The FlexPai measures 7.6mm thick. However, it doesn’t fold flat so it’s thicker than than 15.2mm when folded (certainly near the “hinge”). The hinge is rated to being folded 200,000 times.

The device is powered by a 7nm Qualcomm chipset and only the Snapdragon 8150 fits that description. The base configuration has 6GB of RAM and 128GB storage, but other options include 8/256 and 8/512GB. A proprietary Ro-Charge fast charging tech is supported – it goes from 0% to 80% in an hour.

The price starts at CNY 9,000 – $1,300/€1,135 – which doesn’t seem so high considering that some Android flagships cost that much without a next-gen chipset or a foldable design.

The CIA’s communications suffered a catastrophic compromise through Google scraping, killing ~30 agents

From around 2009 to 2013, the U.S. intelligence community experienced crippling intelligence failures related to the secret internet-based communications system, a key means for remote messaging between CIA officers and their sources on the ground worldwide. The previously unreported global problem originated in Iran and spiderwebbed to other countries, and was left unrepaired — despite warnings about what was happening — until more than two dozen sources died in China in 2011 and 2012 as a result, according to 11 former intelligence and national security officials.

[…]

One of the largest intelligence failures of the past decade started in Iran in 2009, when the Obama administration announced the discovery of a secret Iranian underground enrichment facility — part of Iran’s headlong drive for nuclear weapons. Angered about the breach, the Iranians went on a mole hunt, looking for foreign spies, said one former senior intelligence official.

The mole hunt wasn’t hard, in large part, because the communications system the CIA was using to communicate with agents was flawed. Former U.S. officials said the internet-based platform, which was first used in war zones in the Middle East, was not built to withstand the sophisticated counterintelligence efforts of a state actor like China or Iran. “It was never meant to be used long term for people to talk to sources,” said one former official. “The issue was that it was working well for too long, with too many people. But it was an elementary system.”

“Everyone was using it far beyond its intention,” said another former official.

[…]

Though the Iranians didn’t say precisely how they infiltrated the network, two former U.S. intelligence officials said that the Iranians cultivated a double agent who led them to the secret CIA communications system. This online system allowed CIA officers and their sources to communicate remotely in difficult operational environments like China and Iran, where in-person meetings are often dangerous.

[…]

In fact, the Iranians used Google to identify the website the CIA was using to communicate with agents. Because Google is continuously scraping the internet for information about all the world’s websites, it can function as a tremendous investigative tool — even for counter-espionage purposes. And Google’s search functions allow users to employ advanced operators — like “AND,” “OR,” and other, much more sophisticated ones — that weed out and isolate websites and online data with extreme specificity.

According to the former intelligence official, once the Iranian double agent showed Iranian intelligence the website used to communicate with his or her CIA handlers, they began to scour the internet for websites with similar digital signifiers or components — eventually hitting on the right string of advanced search terms to locate other secret CIA websites. From there, Iranian intelligence tracked who was visiting these sites, and from where, and began to unravel the wider CIA network.

[…]

But the events in Iran were not self-contained; they coincided roughly with a similar debacle in China in 2011 and 2012, where authorities rounded up and executed around 30 agents working for the U.S. (the New York Times first reported the extirpation of the CIA’s China sources in May 2017). Some U.S. intelligence officials also believe that former Beijing-based CIA officer Jerry Lee, who was charged with spying on behalf of the Chinese government in May 2018, was partially responsible for the destruction of the CIA’s China-based source network. But Lee’s betrayal does not explain the extent of the damage, or the rapidity with which Chinese intelligence was able to identify and destroy the network, said former officials.

[…]

As Iran was making fast inroads into the CIA’s covert communications system, back in Washington an internal complaint by a government contractor warning officials about precisely what was happening was winding its way through a Kafkaesque appeals system.

In 2008 — well before the Iranians had arrested any agents — a defense contractor named John Reidy, whose job it was to identify, contact and manage human sources for the CIA in Iran, had already sounded an alarm about a “massive intelligence failure” having to do with “communications” with sources. According to Reidy’s publicly available but heavily redacted whistleblower disclosure, by 2010 he said he was told that the “nightmare scenario” he had warned about regarding the secret communications platform had, in fact, occurred.

Reidy refused to discuss his case with Yahoo News. But two former government officials directly familiar with his disclosure and the investigation into the compromises in China and Iran tell Yahoo News that Reidy had identified the weaknesses — and early compromise — that eventually befell the entire covert communications platform.

Reidy’s case was complicated. After he blew the whistle, he was moved off of his subcontract with SAIC, a Virginia company that works on government information technology products and support. According to the public disclosure, he contacted the CIA inspector general and congressional investigators about his employment status but was met with resistance, partially because whistleblower protections are complicated for federal contractors, and he remained employed.

Meanwhile, throughout 2010 and 2011, the compromise continued to spread, and Reidy provided details to investigators. But by November 2011, Reidy was fired because of what his superiors said were conflicts of interest, as Reidy maintained his own side business. Reidy believed the real reason was retaliation.

[…]

“Can you imagine how different this whole story would’ve turned out if the CIA [inspector general] had acted on Reidy’s warnings instead of going after him?” said Kel McClanahan, Reidy’s attorney. “Can you imagine how different this whole story would’ve turned out if the congressional oversight committees had done oversight instead of taking CIA’s word that he was just a troublemaker?”

Irvin McCullough, a national security analyst with the Government Accountability Project, a nonprofit that works with whistleblowers, put the issue in even starker terms. “This is one of the most catastrophic intelligence failures since Sept. 11,” he said. “And the CIA punished the person who brought the problem to light.”

NVIDIA Launches Year-Long Research Residency Program

If you’re a researcher looking to deepen your exposure to AI, NVIDIA invites you to apply to its new AI Research Residency program.

During the one-year, paid program, residents will be paired with an NVIDIA research scientist on a joint project and have the opportunity to publish and present their findings at prominent research conferences such as CVPR, ICLR and ICML.

The residency program is meant to encourage scholars with diverse academic backgrounds to pursue machine learning research, according to Jan Kautz, vice president of perception and learning research at NVIDIA.

“There’s currently a shortage of machine learning experts, and AI adoption for non-tech and smaller companies is hindered in part because there are not many people who understand AI,” said Kautz. “Our residency program is a way to broaden opportunities in the field to a more diverse set of researchers and spread the benefits of the technology to more people than ever.”

Applicants don’t need a background in AI, and those with doctoral degrees or equivalent expertise are encouraged to apply. Residents will work out of our Santa Clara location.
