Micah Lee from The Intercept wants to remind you that all your communications are being spied on, and offers tips on how you can chat securely and anonymously, particularly with journalists, as NSA whistle blower Edward Snowden did. His tips amount to: using Tor, Jabber, and OTR (Off-the-Record messaging), while creating disposable accounts that can't be linked back to you. He includes some specifics for various operating systems, and a number of important tips and caveats, such as:

* Use Tor when you create your chat account, not just when you use it.
* Never login to that account when you’re not using Tor.
* Don’t choose a user name that might betray your real identity — don’t use a pseudonym that you’ve used in the past. Make up a random user name that doesn’t have anything to do with you
* Don’t re-use passwords.
* Be aware of which contacts you communicate with from which secret identity accounts.
* Don’t give any other identifying information to the chat service.
* Don't use your Tor IP address to login to a chat account that’s publicly associated with you.

95 percent of Android phones vulnerable to Stagefright remote MMS exploit

story imageResearchers at security firm Zimperium identified a bug (really, a series of bugs) that puts some 950 million Android phones at risk of hacking, called it "the mother of all Android vulnerabilities." If you are an Android user, the chances that your phone is vulnerable are about 95 percent. No one has exploited the vulnerability and actually hacked someone's phone -- at least, not yet. The security firm shared the information with Google back in April, along with a suggested patch. Hackers could take advantage of it by sending you a multimedia message (MMS) containing malware. Once received, it would give them complete control over the handset and allow them to steal anything on it, such as credit card numbers or personal information.

The key to protecting your phone is to turn off automatic retrieval of multimedia messages. Open your default text messaging app, go to its settings and find the option for auto-retrieving MMS/multimedia messages. Uncheck that box, don't choose to retrieve or open multimedia messages from numbers you don't know, and you should be fairly safe.

A new type of GM rice fights climate change, increases yields

by

story imageAfter three years of field trials in China, a group of international scientists led by Chuanxin Sun at Swedish University of Agricultural Sciences, in collaboration with Chinese and American scientists, have developed a new type of genetically modified rice that could boost food sustainability while fighting climate change..

Rice paddies are one of the largest sources of atmospheric methane, which is thought to be responsible for one-fifth of the global warming effect. The new genetically-modified strain of Nipponbare rice – equipped with a gene taken from barley – emits as little as 1% of the methane. What’s more, the new rice produces significantly higher yield per plant. The reason: More carbon going into rice grains left less carbon to go elsewhere – which ultimately feed microbes that produce methane. Scientists have been working to develop rice with higher-nutrition, low-emissions traits for years, given that the crop that plays such a significant role in the diets of some 3 billion people.

While some experts hail the findings as an important breakthrough, it seems likely to add new fuel to the heated debate over genetically modified (GM) foods. “Right now, Chinese society is very sensitive” to concerns about GM food, Sun said. China, the world’s largest producer of rice, hasn’t allowed a single genetically modified rice variety into its fields. Assuming all further research goes well, the rice still might not be available for quite a while, given the regulatory processes involved.

Carmakers refuse to share usage data with Google, Apple

story imageDespite the fact that drivers frequently use in-car apps from Google and Apple, several carmakers including Volkswagen and Ford are refusing to let the industry juggernauts access private customer information in exchange. If you thought that the companies were doing so out of concerns for their consumers, you’d be wrong. Automakers want to keep such information for their own purposes. This came to light when Reuters published a recent report highlighting the potential windfall that car manufacturers refusing to partake could be missing out on procuring, estimated to be around $40 billion.

The symbiotic relationship sees carmakers utilizing technology to improve the experience for drivers and passengers whilst tech companies are constantly seeking out new outlets for their gear. Technology has now become synonymous with many drivers’ experiences. Many cars now make use of Apple’s CarPlay service and Google’s Android Auto. The risks of not playing ball with big tech companies include losing out on a sustained and promising source of revenue. Car companies may attempt to do an end-run around Apple and Google by manufacturing their own in-car tech apps, but their past record with vehicle infotainment and navigation systems has been poor. Consumer Reports found "significant rates of complaints" and called them "distracting", “unintuitive and frustrating”.

Who's Afraid of Systemd?

Now that systemd is uneventfully running the latest releases of major distributions like Debian, Fedora, and Ubuntu, you might imagine that opposition to it is melting away -- but you'd be wrong. Instead, the rumors are as common as ever. Devuan, the anti-systemd fork of Debian, is still trudging towards a release while making the same arguments as ever. Devuan's home page asks: Have you tried to opt-out of the systemd change in Debian and stay with sysvinit? You will quickly notice that "Debian offers no choice." Yet a search quickly unearths instructions for making an install image without systemd and for removing systemd from your system.

Nor does the claim that systemd violates the Unix design principles stand up under scrutiny. Systemd is actually a general name for a series of related, similarly structured commands. From this perspective, systemd conforms to the principle of one program doing a single function in much the same way as the Linux kernel or a command line shell does. It is a suite of programs, not a single monolithic one. Systemd may not be ideal, but systems continue to boot and function the way they are supposed to.

In fact, not only are the most common anti-systemd arguments easily discounted, but they are surrounded by a vagueness that raises suspicions. Wild claims are made without any attempt at substantiation. The result is an air of secrecy and danger that, however appealing and reminiscent of freedom-fighting that it might be, does nothing to justify the anti-systemd rhetoric or make it plausible. Devuan's mailing list mostly shows the same dozen or so posters, and has raised only 7934 Euros. Supporters sound as though they are doing more fear-mongering than constructive effort.

Natural gas surpasses coal as top source of electricity in US

by
in environment on (#F84J)
story imageFor the first time ever, natural gas trumped coal as the top source of electric power generation in the U.S. In April, roughly 31 percent of electric power generation came from natural gas, whereas coal accounted for 30 percent. It's a dramatic difference from April 2010, when coal accounted for 44 percent of the mix and natural gas just 22 percent. In last 18 months, 17 gigawatt hours of coal-fired capacity has been retired completely, much of it already replaced by gas generation. "It could be the beginning of the end for the current fleet of coal plants."

As domestic demand at power plants has been falling, global demand for U.S. coal exports also continues to sag. On Monday Chinese customs data showed coal imports in China plunged 33.7 percent in June versus a year earlier. China is the largest consumer of the commodity in the world. U.S. coal exports have been in free fall for years as countries like Australia and Indonesia have provided supply to China more inexpensively. The stronger dollar is also making American supply pricier abroad.

Coal prices have continued to crater. This is particularly true of coal mined in the eastern U.S. Since their 2011 peak, prices have nearly halved. But the ripple effects extend beyond coal stocks. Coal, a historically high-margin business for railroads, accounted for nearly 19 percent of revenue for the Class I railroads in the U.S. in 2014. Of the 1.8 billion tons of freight transported via rail in 2014, 39 percent was coal.

Microsoft admits failure in Nokia acquisition

story imageWhen Microsoft announced its deal to acquire Nokia’s mobile phone business, Steven A. Ballmer, Microsoft’s chief executive at the time, boasted that the deal was a “bold step into the future.” But on Wednesday, Microsoft’s current chief executive, Satya Nadella, sought to leave that deal in the past. He announced a broad rethinking of the company’s phone strategy, a change that includes cutting up to 7,800 jobs, mostly from the phone business, and writing off nearly all of the value of its Nokia acquisition. The move is a clear acknowledgment that the deal was a multibillion-dollar strategic blunder by Mr. Ballmer, who had envisioned it as a way to make Microsoft more competitive in the mobile market.

While Microsoft will not stop making smartphones, Mr. Nadella said on Wednesday that it would no longer focus on the growth of that business. Microsoft has continued to lose market share in smartphones since acquiring Nokia’s handset business. The company has failed to turn the Windows Phone operating system, which runs on its handsets, into a vibrant alternative to the two leading mobile platforms, iOS from Apple and Android from Google.

This has been “a big blow” for Finland's economy. The "death curve" of their electronics industry as Nokia faltered and fell to just 2-3 per cent of the global smartphone market, along with falling global demand for paper products and EU sanctions on neighboring Russia, have entrenched the Scandinavian country in a three-year recession. Meanwhile, Nokia has confirmed rumors that it intends to reenter the smartphone market. Nokia certainly won’t be recouping the massive investment required to start manufacturing smartphones again, instead they would design the products and earn the royalties, but everything else would be up to whomever they partner with.

Solar Impulse 2 grounded in Hawaii after record-breaking flight across Pacific Ocean

by

story imageSolar Impulse 2 has successfully landed in Hawaii after completing its audacious five-day journey across the Pacific Ocean. The mission, which has been dogged by recent delays, touched down safely at Kalaeloa Airport with Swiss pilot André Borschberg in the cockpit. He had endured more than 100 hours alone in the plane with minimal sleep during the flight - smashing the record for the longest solo flight in aviation history by two days. The plane had originally been intended to fly straight from China to Hawaii, but worsening weather on the way meant Borschberg had to abort and land in Japan. Bad weather had also kept the plane grounded in China for several weeks longer than intended.

The next leg of the global circumnavigation flight was to be a four-day crossing to Phoenix, Arizona, but that has been postponed at least until 2016. The plane's batteries overheated and were damaged beyond repair during the latest leg of the trip. It's not the technology itself that was the problem, the pilots say, but how the batteries were insulated. Replacing and testing the batteries will take at least a few months, and because the days in the Northern Hemisphere are already getting shorter, completing the rest of the journey in 2015 isn't an option.

The flight began in March over the desert sands of Abu Dhabi, and flown across Oman, India, Myanmar, China, Japan, and the Pacific Ocean. If all goes to plan, Bertrand Piccard will fly the next leg to Phoenix, Arizona, sometime in April. Piccard and Borschberg will alternate flying across the U.S., the Atlantic, and eventually all the way back to Abu Dhabi, completing the 35,000 kilometer (22,000 mile) journey.

Tropical pitcher plant communicates with bats

by
in science on (#EF9K)
Native to the forests of Borneo, Nepenthes hemsleyana feeds on bat guano, which provides the plant with all the nutrients it needs, minus the hassle of digestion. To that end, N. hemsleyana has developed special structures that reflect bats’ ultrasonic calls back to them – an ability that helps the plant attract bats to roost in its pitcher so that it can feast on the animal’s feces, a new study has found. The signals are specific to the bat species Kerivoula hardwickii, making it easier for the bats to find their partner plant.

Unlike its carnivorous cousins, N. hemsleyana is not especially adept at catching insects. Yet scientists noticed that it somehow manages to thrive. Pursuing the mystery, Schöner and his team discovered that N. hemsleyana provides some insect-eating bats with a spacious, stable, and parasite-free roosting spot. In return, the bats fertilize the plant with their feces, the researchers discovered. “Carnivorous plants in general have already solved the problem of nutrient deficiency in a very unusual way by reversing the ‘normal system’ of animals feeding on plants. It is even more astonishing that in the case of N. hemsleyana the system is taking a new turn,” Dr. Schöner said.

Large Hadron Collider discovers new pentaquark particle

story imageAfter restarting to run at higher power than ever, the Large Hadron Collider has made its first proper discovery. Today, a team of scientists announced that they’ve found a new class of sub-atomic particles known as pentaquarks, a particle composed of four quarks and an antiquark.
From BBC:
It was first predicted to exist in the 1960s but, much like the Higgs boson particle before it, the pentaquark eluded science for decades until its detection at the LHCb experiment. The findings have been submitted to the journal Physical Review Letters.
The LHCb experiment is an experiment set up to understand what allowed matter to survive (as opposed to antimatter) by studying the properties of quarks.
