Moshe Greenshpan is the founder and CEO of Skakash, an Israeli company that aims to provide churches with a program called Churchix to scan everyone who walks through their holy halls. The program was covered in a VentureBeat interview with Greenshpan back in February, and enjoyed a string of recent coverage in European outlets like Der Spiegel and The Times. It sounded wild, so I called Greenshpan to find out more.
But, when I asked Greenshpan in our interview if he could provide the names of some of his clients so that I could speak with them about their use of facial recognition, he was reticent—a theme that would develop throughout our conversation as he refused to confirm numerous details about his operation.
"I can tell you in general that churches also don't like to be described as privacy invaders," Greenshpan told me. "Most of them would like to keep this confidential. We try to encourage churches to make Churchix more visible, so it will become like a checkpoint for registration. Of course, so far we haven't had great success in doing that."
Comment: It seems there is no remaining place outside your own home that you cannot be spied upon without your knowledge or consent, and now you can add your local house of worship to the list of places where you are tracked.

When one installs an open source Chromium browser, as it turns out, it "downloads something" followed by a status report that says "Microphone: Yes" and "Audio Capture Allowed: Yes," according to an article by Rick Falkvinge, Swedish Pirate Party founder, published on the website Privacy Online News.
While the Chromium, the open source basis for Google's browser, at least shows the code and allows user to notice it and turn it off, the same installation is included by default in the most popular browser Chrome, used by over 300 million people.
The code was designed to enable the new "OK, Google" hot word detection, which lets the computer do things like search or create reminders in response to human voice. Yet, some users are worried that the service could be activated without their permission, eventually sending recorded data to Google. The worried users describe the Chrome Hotword Shared Module as an audio-snooping "black box", with only the corporation that provided it fully aware of what the injected pre-compiled code is capable of.

The craft took the photographs on June 9 from a distance of 2,700 miles (4,300 kilometers). It revealed a number of new geographical characteristics, in particular, the high peak that juts out from the surrounding landscape.
"The surface of Ceres has revealed many interesting and unique features. For example, icy moons in the outer solar system have craters with central pits, but on Ceres central pits in large craters are much more common. These and other features will allow us to understand the inner structure of Ceres that we cannot sense directly," said Carol Raymond, deputy principal investigator for the Dawn mission, based at NASA's Jet Propulsion Laboratory in Pasadena, California.

The geomagnetic storm was classified G4, the second-highest possible degree - the last on such a scale happened in March, when auroras were seen as far south as New Mexico.

A team of researchers took blood samples from Leningrad siege survivors to analyze the structure of the genes involved in metabolism and cell activity when facing severe food shortages. They compared their findings with genetic samples of elderly Russians who did not live through similar horrors.
Many siege survivors who suffered the worst turned out to have a completely different structure of two genes related to PPAR (peroxisome proliferator-activated receptors) proteins, and one from the UCP (uncoupling proteins) gene family, which play major roles in development, metabolism and thermogenesis of higher organisms.
The inhabitants of the besieged city, now known as St. Petersburg, had these genes undergo a mutation that increased the efficiency of the cells' activities and reduced the loss of energy invested in keeping the body warm, according to an article, recently published in the journal Science.
Comment: About 20 to 30 percent of the population has those markers? We wonder if a similar percent of the population had better chances of survival during the past cataclysms, like the Ice Age.

When it comes to mother-baby connections, new research suggests a mother's touch during pregnancy elicits the greatest response.
In a recent study published in the journal PLOS ONE, researchers looked at what behaviors resulted in the greatest response from fetuses: a mother's voice, a mother's touch or nothing. The researchers brought 23 healthy pregnant women who were between the 21st and 33rd week of gestation into a dark room, and had them try three different behaviors.
Two weeks before that date the French astronomer Charles Messier had discovered a faint comet in the constellation Sagittarius, which thereafter rapidly brightened and began moving swiftly across the sky. At its peak it was naked-eye, and its coma, according to various observers, the apparent size of from 5 to 16 full moons across. Lexell's Comet, so named after another astronomer who subsequently calculated its orbit, was then under one-and-a-half million miles from Earth, or less than six times the distance of the Moon, and thus the nearest a comet has ever approached us in recorded history. (Kronk n.d.)
It was also larger than any asteroid known to have come that close, and in fact large enough to have wrought global consequences had it impacted our planet. The comet's nucleus is estimated to have been 5 kilometers in diameter, or approximately half that of the comet or asteroid that wiped out the dinosaurs.
It is a curious fact of history that the celestial spectacle most superstitiously associated with presaging calamity has now been given scientific legitimacy as a major threat to human existence. (Bayle 2000 & Genuth 1997) It is an ironic fact of very recent times that the celestial spectacle most popularly associated in times past with presaging calamity and now known to have this potential in fact, is today looked upon mainly as a showpiece and photo op by much of the public and amateur astronomical community and as a scientific opportunity by the professional astronomical community. I refer in both instances to the appearance of a new comet.
These are thus the best of times and the worst of times for planetary defenders against potential impactors from outer space, since, on the one hand, for the first time since the Earth came into being, some of its inhabitants have an accurate awareness of the nature of this hazard and even the technological potential to do something about it, while, on the other hand, insufficient steps are being taken to protect us from it. What is most needed, I submit therefore, is a raising of comet consciousness among both the general and expert populace, who are currently, to coin a term, cometose.
And how better to do this than to institute a Comet Day? Global recognition has just been rallied for analogous awareness with the first annual Asteroid Day. This took place yesterday, on the anniversary of the largest impact event in recorded history, which occurred on June 30, 1908, in (or over) Tunguska, Siberia. The resulting explosion of the object upon penetration of the atmosphere would have obliterated any major metropolitan area that happened to lie beneath it. Current estimates are of one million objects of this or greater size in the Earth's vicinity, only one percent of which have been discovered and are being tracked to date. The purpose of Asteroid Day is to build a global consensus for finding all the rest as soon as possible, to give us time to devise a suitable defense against any that might be heading our way.

But even if physicists could completely isolate a large object in a quantum superposition, according to researchers at the University of Vienna, it would still collapse into one state—on Earth's surface, at least. "Somewhere in interstellar space it could be that the cat has a chance to preserve quantum coherence, but on Earth, or near any planet, there's little hope of that," says Igor Pikovski. The reason, he asserts, is gravity.
Pikovski and his colleagues' idea, laid out in a paper published in Nature Physics on June 15, is at present only a mathematical argument. But experimenters hope to test whether gravity really does collapse quantum superpositions, says Hendrik Ulbricht, an experimental physicist at the University of Southampton, UK. "This is a cool, new idea, and I'm up for trying to see it in experiments," he says. Assembling the technology to do so, however, may take as long as a decade, he says.

They found evidence of fluidisation (where soil behaves like quicksand) and upward displacement of material unprecedented in a continental setting, raising questions of how resilient the rapidly growing cities of the region would be in a major shake.
'We can now use this to evaluate how the ground would deform in a modern earthquake,' said Dr. Roberts. 'This is important because the approach is inexpensive and can be used to model how structures might be affected by future events, providing a valuable tool in hazard assessment.'
Hilbert-Wolf said the team found evidence of massive ground deformation and previously unknown styles of liquefaction and fluidisation, caused by past earthquakes. 'This could be a major concern for the growing urban population of East Africa, which has similar tectonic settings and surface conditions,' she said.
The study comes on the back of a series of damaging earthquakes already this year, including in Nepal and Papua New Guinea and the study may be of much use in predicting the effects of earthquakes in those countries.
'What we have shown is that in developing countries in particular, which may lack extensive seismic monitoring, the rock record can be used to not only investigate the timing and frequency of past events, but also provide important insights into how the ground will behave in certain areas to seismic shock,' said Hilbert-Wolf.

The impacts that made the Popigai crater in Siberia and the Chesapeake Bay crater on the US East Coast were two of the largest asteroid strikes since the one that killed the dinosaurs, so big that their dust left thin layers of debris all over the globe.
The depth of debris layers shows that the asteroids struck in quick succession - within 20,000 years of each other, around 36 million years ago. A Popagai-sized impact happens just once every 20 million years. So the thinking was that the two rocks were fragments of one larger asteroid.
But when Birger Schmitz of Lund University in Sweden examined sediment from a site in central Italy containing debris from both impacts, he found two distinct types of meteoritic grains. Those from the part of the deposit associated with Popigai were rich in iron; those from the part associated with Chesapeake Bay were iron-poor. So the pair can't be explained by a single body breakup - they must be from two separate asteroids (Earth and Planetary Science Letters, doi.org/5cb).
But how could that happen? One explanation is that chaos in the inner solar system disturbed asteroids' orbits, sending several Earthwards.
It's even possible that a change in Earth's own orbit sent the asteroids on their paths. Such a shift might explain why Earth entered an ice age around 35 million years ago: a new orbit meant less energy from the sun.
