‘Mythbusters’ reboot comes to Science Channel on November 15th

What do you do when your highly-successful reality show goes out with a bang? If you’re Discovery-owned Science Channel, you quickly reboot it and find new hosts to replace the iconic ones. If you’re a fan of the original and willing to give the new guys a chance to prove themselves to be as awesome as Adam and Jamie are, then your’e in luck. The new version of Mythbusters, a much-loved show that reveled in DIY gadgetry and science, is set to air its first of 14 episodes on November 15th.

Jon Lung and Brian Louden will anchor the new series, which aims to continue the original’s mission to debunk fantastic claims and myths using actual science. The first episode will have the leads testing to see if an airbag can be lethal to front-seat passengers who put their feet on the dashboard. Of course, they’ll use a cadaver to do so. In addition, the team will test out whether a bad guy or zombie will hold still for a dramatic pause if you decapitate them with enough force like they do in the movies. A rocket-powered sword will be their instrument of truth.

Louden and Lung won a national talent search in Mythbusters: the Search, beating out 9 other teams who wanted to host the reboot. Louden has a biology degree and has trained in emergency medicine while Lung is an engineer and product designer.

Samsung’s phone-as-desktop concept now runs Linux

Samsung’s DeX is a clever way to turn your phone into a desktop computer. However, there’s one overriding problem: you probably don’t have a good reason to use it instead of a PC. And Samsung is trying to fix that. It’s unveiling Linux on Galaxy, an app-based offering that (surprise) lets you run Linux distributions on your phone. Ostensibly, it’s aimed at developers who want to bring their work environment with them wherever they go. You could dock at a remote office knowing that your setup will be the same as usual.

It’s not quite the same as your typical Ubuntu or Debian install. Linux on Galaxy launches through an app, and it’s using the same kernel as Android itself in order to maintain performance. And it almost goes without saying that you’ll really want a DeX setup, since most Linux apps are expecting a large screen, mouse and keyboard.

As it stands, you’ll have to be patient. Linux on Galaxy isn’t available right now — you can sign up for alerts, but it’s not ready for public consumption. Even so, this is good evidence that Samsung thinks of DeX as considerably more than a novelty feature. It may be a long, long while (if ever) before many people are using their phones as desktops, but Samsung is willing to gradually build up its ecosystem and eventually give you an incentive to take a second look.

The way scientific units are calculated is changing

Scientific units are set to receive their biggest shake-up since the inception of the modern metric system in 1960. The International Bureau of Weights and Measures (BIPM) — one of three committees that oversees this type of stuff — is presently looking into revising the ampere, the kilogram, the kelvin, and the mole. The higher-ups at the General Conference on Weights and Measures will then conduct a final vote on the recommendations next year, before ordering them into effect in May 2019. Although it may not impact everyday measurements, the redefinition is crucial for scientists, who require the utmost accuracy for their work.

Ever pondered the precision of the international system of units (SI)? (Why should you? You’re not going to be called on to measure the temperature in the Large Hadron Collider any time soon). You may be in need of a refresher, then. The kilogram is defined as the lump of platinum-iridium locked in a vault in Paris. The artefact is known to fluctuate in weight (due to surface contamination), making it tricky to define its exact mass.

But, it made the cut for its inclusion in the broader redefinition of units with the acceptance of the so-called watt balance method in 2015. This approach essentially compares mechanical power with electromagnetic power using two methods — which measure speed as well as experimental values relating the voltage and current in Planck’s constant.

An ampere (the base unit of electric current, often shortened to "amp") is presently defined by an imaginary experiment involving the force between two infinite wires. In the near future, the unit could be measured using an electron pump. Meanwhile, the mole is the unit for the amount of substance in a system with as many elementary entities as there are atoms in 0.012 kilograms of carbon-12. In just a couple of years, it could be defined using the silicon sphere (the device that gives scientists Avogadro’s constant).

Finally, the Kelvin — the base unit for temperature — relates to little more than water: The triple point of water to be exact. The redefinition would rely on the Boltzmann constant, which scientists measured using a dielectric-constant gas thermometer. By grounding the SI on an invariable foundation of constants, scientists should be able to pin down their definitions for good. Roll on, 2019.

Octopus-like rubber skin could lead to shape-shifting robots

Octopuses are awe-inspiring creatures. They’re smart, and they can camouflage themselves by changing colors and changing the texture of their skin to mimic the environment’s. A group of scientists from Cornell University in New York and the Marine Biological Laboratory in Massachusetts wanted to give soft robots the same ability, so they created a synthetic elastic skin that can morph into different shapes and change textures.

The team designed a material based on the muscle underneath octopus skin that controls the animal’s dermal papillae. Those are the protrusions in the cephalopod’s skin that pop up when it wants to blend into its surroundings. That material is composed of several layers, including a fiber mesh and the rubber skin itself. When you pump air into the structure, some parts of the skin expand, while others get held back by the mesh to form various shapes, like rocks and plants.

The team still has a lot of work to do to perfect their creation, including giving it the ability to form multiple shapes at once. But in the future, the material could be used not to only to create soft robots with the ability to camouflage themselves, but also to immersive VR experiences. Imagine coming across a strange alien from another planet and being able to touch its skin with the help of a prop. Sounds cool, doesn’t it?

Google Play apps with as many as 2.6m downloads added devices to botnet


reader comments

Google has booted eight Android apps from its Play marketplace, even though the apps have been downloaded as many as 2.6 million times. The industry giant took action after researchers found that the apps add devices to a botnet and can perform denial-of-service attacks or other malicious actions.

The stated purpose of the apps is to provide a skin that can modify the look of characters in the popular Minecraft: Pocket Edition game. Under the hood, the apps contain highly camouflaged malware known as Android.Sockbot, which connects infected devices to developer-controlled servers. This is according to a blog post published Wednesday by researchers from Symantec. The malware mostly targets users in the US, but it also has a presence in Russia, Ukraine, Brazil, and Germany.

When the researchers ran an infected app in their laboratory, they found it establishing a persistent connection based on the Socket Secure (SOCKS) protocol to a server that delivers ads. The SOCKS proxy mechanism then directs the infected device to an ad server and causes it to request certain ads be displayed.

“This highly flexible proxy topology could easily be extended to take advantage of a number of network-based vulnerabilities, and [it] could potentially span security boundaries,” the Symantec researchers wrote. “In addition to enabling arbitrary network attacks, the large footprint of this infection could also be leveraged to mount a distributed denial of service (DDoS) attack.”

The post showed that one of the abusive apps was called Assassins Skins for Minecraft. The post didn’t name the other seven apps. Google Play showed that the apps had been downloaded from 600,000 to 2.6 million times before they were removed.

Wednesday’s post should serve as a reminder that Google is chronically unable to detect untrustworthy apps before allowing them into its official app bazaar. This puts Android users in a difficult predicament that requires them to carefully think through a list of considerations before installing an app. These considerations include how useful or valuable the app truly is, whether it comes from a recognized developer that has been operating for a long time, and whether other users have left comments reporting suspicious behavior. The vetting process is by no means foolproof, and for that reason, users in doubt should always choose not to install an app.

The Trump National Golf Club in Rancho Palos Verdes, seen in 2005, has removed a list of charitable donations it once posted on its website. An NPR examination of that list reveals inconsistencies and errors.

Throughout his presidential campaign and since, President Trump has made bold assertions about his charitable giving. But as the Washington Post has thoroughly documented, those boasts of philanthropy don’t always stand up to scrutiny.

Now NPR has taken a closer look at the charitable-giving claims made by a Trump property — the Trump National Golf Club, Los Angeles. We have found that the golf club’s charitable giving has followed the same pattern — falling far short of what the organization claimed.

As recently as this summer, the club declared on its website: “We are proud to have provided $5 million to the following charitable causes since our opening.” It listed nearly 200 recipients.

For weeks, NPR’s Embedded podcast and Conflicts of Interest team combed through that list to verify the assertions. NPR cross-referenced the golf club’s website with a document that the Trump campaign gave to the Associated Press in 2015, detailing charitable gifts from 2010 to 2015. NPR also called and emailed dozens of organizations to find out whether they have a record of a donation from Trump National Golf Club, the Trump Organization or VH Property Corp., the LLC that technically owns the golf course.

That reporting suggests the club’s donations have fallen well short of $5 million, and are much closer to approximately $800,000.

NPR has repeatedly contacted the Trump Organization and the golf club manager, sending questions via phone calls, emails, letters and a fax message. They have not responded.

However, the club did change its assertions. In early September, about a month into NPR’s reporting, the Trump Organization took down the list of organizations from its website, and removed the claim about having donated $5 million. (You can still view the page via the Internet Archive as well as archive.is. For comparison, here is the current webpage.)

To be clear, NPR did confirm that the club, located outside of Los Angeles in Rancho Palos Verdes, has made charitable donations. The discrepancies involve the amounts of gifts and numbers of recipients.

Through interviews and examinations of publicly available documents, here’s what NPR has found:

  • 17 organizations listed on the Trump National website said that they could not find any record of a donation from the golf club.
  • Several organizations listed on the website are not charities at all. The list includes a city government, a state agency and a branch of the U.S. military.
  • Most organizations received small contributions from the golf club, including donations of $140. Most of the contributions to organizations on the list were not in the form of cash, but in-kind donations, like a gift certificate for a round of golf or “Sunday brunch for two.”
  • In the end, NPR was able to confirm only about $800,000 in donations, less than one fifth of what was claimed.

Missing donations and discrepancies

As several organizations pointed out, the fact that 17 of them could not find a record of a donation does not necessarily mean they never received one. It could suggest that the donations were not significant enough to be remembered or written down, or it might be chalked up to a lack of precision in naming the recipients.

For example, the Trump Campaign document listed more than $21,000 in donations to the “UCLA Foundation” and the “UCLA Women’s Golf Program.” Brian Haas, a spokesperson for the university, said UCLA searched multiple times for records of donations, but came up empty-handed.

“We are unaware of these particular donations,” Haas wrote in an email. “If you can coax some additional information from the Trump Organization, perhaps that would help.”

The Trump website also cited a donation to “Cystic Fibrosis” — as in the genetic disease, rather than a specific charity supporting research. The Trump Campaign document also has an entry for a $1,182.50 donation to “Child Abuse.”

Several organizations listed are not charities at all, such as the City of Avalon, Calif., and the California Department of Veterans Affairs. Both said they could find no record of a donation from Trump or his golf club.

Then there’s the entry for a $152.14 donation to the “U.S. Department of the Navy.” (That amount indicates the donation was for a gift certificate for “Sunday Brunch For Two” at the golf club.) In an email, a Navy official told NPR, “We have no information about whether or how this specific gift was given to the Navy.”

But a handful of organizations in the Rancho Palos Verdes area do reporting receiving “generous” cash contributions.

One example comes from John Williams. A former Kiwanis Club president, Williams now runs the Peninsula Symphony, a small orchestra that performs free concerts. He says Trump helped support the Kiwanis Club’s Palos Verdes Marathon from 2005 to 2007, with three donations of $15,000 each, and has supported the Symphony through in-kind donations.

“I would have to say he’s been a very good community supporter,” Williams said.

In-kind donations

NPR’s other key finding was that overwhelmingly, charitable giving by Trump National involved gift certificates, such as the “Sunday brunch for two” or “twosome for golf” (worth approximately $600).

The Washington Post has documented that Trump properties around the country also prefer this type of donation. Some nonprofits welcome such gifts.

Judith Opdahl, the executive director of the Cancer Support Community Redondo Beach, did not offer specific dollar amounts, but says the Trump Organization has been “very philanthropic” by providing discounted event space and in-kind donations for charity auctions.

Daniel Borochoff, of the charity watchdog CharityWatch, says many companies use in-kind donations as a way to promote their business and build goodwill.

“If the public or potential customers have good feelings towards the business, they’re more likely to play golf there or shop there,” Borochoff said.

But he is skeptical about the value of such philanthropy, noting that such donations help build the Trump brand and bring in new customers.

“It may not be altruism,” Borochoff said. “It may just be marketing his business.”

Borochoff says another reason companies offer in-kind donations is because such gifts rarely cost the company much money. They also frequently come with strings attached.

For example, a charity event held by Concordia University Irvine auctioned a “twosome of Golf” at the Trump golf club. But the gift certificate was only valid from Mondays through Thursdays and expired within six months.

In most cases, experts say, cash donations are also much more valuable to a charity than in-kind donations. To turn a gift certificate into cash, a charity typically must hold an auction, which takes time and effort. And the bid usually comes in at less than the market value of the in-kind donation.

Jacob Harold, the president of GuideStar, which tracks nonprofits, says when companies claim an in-kind donation is worth the full sticker price, it can create a false impression.

“If you are saying, ‘We gave $5 million away over the last few years,’ and that’s at market prices,” says Harold, “that’s actually somewhat misleading.”

A controversial source for the $5 million estimate

So how does the total charitable giving of Trump’s golf club stack up? NPR was able to verify only about $800,000 in charitable gifts, even treating in-kind donations at full-market value.

Because the Trump Organization did not respond, NPR could not ask how the club reached the $5 million figure listed on its website.

It’s possible the club was including a sometimes-controversial federal tax break: conservation easements.

In January 2015, Trump made an agreement with the Palos Verdes Peninsula Land Conservancy to set aside the golf course’s 11.5 acre driving range as environmentally valuable open space.

“The easement protects the land and prohibits harmful uses on the property such as dumping, landfill, and also has restrictions on waste and impermeable surfacing among many other items,” said a press release from the land conservancy. Trump said the easement represented a significant gift, because the land was worth “much more than $25 million,” and he could make a windfall if he built and sold houses on that property.

Though, as the Associated Press has reported, it’s unclear if Trump ever had concrete plans to build houses on the property. City officials also told NPR that Trump faced significant barriers to building because of the area’s geologic instability.

Conservation easements can help protect the environment, and can also offer valuable tax breaks for companies, especially golf courses. They’ve also come under increased scrutiny from the Internal Revenue Service.

Trump’s California golf course before and after the agreement looks the same. The driving range is still a driving range.

“The smell test isn’t great in that case,” Harold, of Guidestar, said. Claiming a charitable donation for preserving a driving range as open space “doesn’t feel like a sacrifice.”

It’s unclear what, if any, deductions Trump or the Trump Organization claimed from the easement agreement. The land conservancy itself says it does not assign dollar values to the land. So that may be a question only Trump’s tax returns could answer.

He has not released those.

If your organization has received a donation from Trump National Golf Club, Los Angeles, or if you believe your organization was wrongly included on the golf club’s website, please let us know. You can reach Tom Dreisbach at tdreisbach@npr.org
