Study shows limited control over privacy breaches by pre-installed Android apps

Yahoo Science News feed latest items - Mon, 03/25/2019 - 09:11

The study did not look at whether the EU's General Data Protection Regulation laws would bring greater oversight to pre-installed apps on Android devices. The study found the setup posed a potential threat to users' privacy and security because the pre-installed apps request access to data that similar apps distributed through Google's Play app store cannot reach. Pre-installed apps often cannot be uninstalled, and Google may not be performing as rigorous security checks of them as it does for app store versions, the researchers found.

World's Largest Atom Smasher May Have Just Found Evidence for Why Our Universe Exists

Yahoo Science News feed latest items - Mon, 03/25/2019 - 06:58

For the first time ever, physicists at the world's largest atom smasher have observed differences in the decay of particles and antiparticles containing a basic building block of matter, called the charm quark.The finding could help explain the mystery of why matter exists at all."It's a historic milestone," said Sheldon Stone, a professor of physics at Syracuse University and one of the collaborators on the new research. Matter and antimatterEvery particle of matter has an antiparticle, which is identical in mass but with an opposite electrical charge. When matter and antimatter meet, they annihilate one another. That's a problem. The Big Bang should have created an equivalent amount of matter and antimatter, and all of those particles should have destroyed each other rapidly, leaving nothing behind but pure energy. [Strange Quarks and Muons, Oh My! Nature's Tiniest Particles Dissected]Clearly, that didn't happen. Instead, about 1 in a billion quarks (the elementary particles that make up protons and neutrons) survived. Thus, the universe exists. What that means is that particles and antiparticles must not behave entirely identically, Stone told Live Science. They should instead decay at slightly different rates, allowing for an imbalance between matter and antimatter. Physicists call that difference in behavior the charge-parity (CP) violation.The notion of the CP violation came from Russian physicist Andrei Sakharov, who proposed it in 1967 as an explanation for why matter survived the Big Bang."This is one of the criteria necessary for us to exist," Stone said, "so it's kind of important to understand what the origin of CP violation is."There are six different types of quarks, all with their own properties: up and down, top and bottom and charm and strange. In 1964, physicists first observed the CP violation in real life in strange quarks. In 2001, they saw it happen with particles containing bottom quarks. (Both discoveries led to Nobel prizes for the researchers involved.) Physicists had long theorized that it happened with particles containing charm quarks, too, but no one had ever seen it. Charmed, I'm sureStone is one of the researchers on the Large Hadron Collider (LHC) beauty experiment, which uses CERN's Large Hadron Collider, the 16.5-mile (27 kilometer) ring on the French-Swiss border that sends subatomic particles careening into one another to re-create the flashes of mind-boggling energy that followed the Big Bang. As the particles smash into each other, they break into their constituent parts, which then decay within fractions of a second to more stable particles.The latest observations involved combinations of quarks called mesons, specifically the D0 ("d-zero") meson and the anti-D0 meson. The D0 meson is made up of one charm quark and one anti-up quark (the antiparticle of the up quark). The anti-D0 meson is a combination of one anti-charm quark and one up quark.Both of these mesons decay in many ways, but some small percentage of them end up as mesons called kaons or pions. The researchers measured the difference in decay rates between the D0 and the anti-D0 mesons, a process that involved taking indirect measurements to ensure they weren't just measuring a difference in the initial production of the two mesons, or differences in how well their equipment could detect various subatomic particles.The bottom line? The ratios of decay differed by a tenth of a percent."The means the D0 and the anti-D0 don't decay at the same rate, and that's what we call CP violation," Stone said.And that makes things interesting. The differences in the decays probably isn't big enough to explain what happened after the Big Bang to leave behind so much matter, Stone said, though it is large enough to be surprising. But now, he said, physics theorists get their turn with the data. [Big Bang to Civilization: 10 Amazing Origin Events]Physicists rely on something called the Standard Model to explain, well, everything at the subatomic scale. The question now, Stone said, is whether the predictions made by the Standard Model can explain the charm quark measurement the team just made, or if it will require some sort of new physics -- which, Stone said, would be the most exciting outcome."If this could only be explained by new physics, that new physics could contain the idea of where this CP violation is coming from," he said.Researchers announced the discovery in a CERN webcast and published a preprint of a paper detailing the results online. * What's That?

Day and Night Are Perfectly Balanced in Spring Equinox Photo Snapped from Space

Yahoo Science News feed latest items - Mon, 03/25/2019 - 06:58

Earth just got another dazzling glamour shot, thanks to a satellite that snapped its photo on the March 20 spring equinox. This photo shows half of the planet illuminated in light, and the other steeped in darkness, just like a black-and-white cookie.This beautiful symmetry is no surprise for anyone who knows anything about the equinox. In Latin, equinox means "equal night." Twice a year, in March and September, the equinox happens when the amount of daylight and darkness are nearly equal at all latitudes, according to the National Oceanic and Atmospheric Administration (NOAA).Why aren't equinoxes more common? The answer has to do with Earth's tilt. Because the planet is tilted on its axis about 23.5 degrees, daylight is usually unequally distributed across the planet. Depending on where Earth is in its orbit around the sun, either the Northern Hemisphere or the Southern Hemisphere will have longer days or nights. [Earth Pictures: Iconic Images of Earth from Space]"During two special times twice a year, the tilt is actually perpendicular to the sun, which means that Earth is equally illuminated in the Northern and Southern hemispheres," C. Alex Young, associate director for science in the Heliophysics Science Division at NASA's Goddard Space Flight Center, previously told Live Science.In other words, the sun is directly above the equator at noon during an equinox.This past week, the equinox happened at 5:58 p.m. EDT on Wednesday (March 20), marking the first astronomical day of spring for the Northern Hemisphere. The new image, however, was taken several hours before that, at 8 a.m. EDT, by the GOES EAST satellite.Then GOES satellites, also known as the Geostationary Operational Environmental Satellite system, are a network of Earth-observing satellites operated by NOAA. They gather information on weather forecasting, severe storm tracking and meteorology research. * 2013 Amazing Earth Images * Photos: 2017 Great American Solar Eclipse * See Gorgeous Pics of the SuperBlueBloodMoon EclipseOriginally published on Live Science.

Astronomers Find Fossils of Early Universe Stuffed in Milky Way's Bulge

Yahoo Science News feed latest items - Mon, 03/25/2019 - 06:57

Astronomers peered into the dusky bulge of the Milky Way and found some of the oldest known stars in the universe.In a study to be published in the April 2019 issue of the journal Monthly Notices of the Royal Astronomical Society, researchers analyzed a cluster of old, dim stars called HP1, located about 21,500 light-years away from Earth in the gut of our galaxy's central bulge. Using observations from Chile's Gemini South telescope and archival Hubble Space Telescope data, the researchers calculated the age of the stars to be roughly 12.8 billion years old -- making them some of the oldest stars ever detected in either the Milky Way or the universe at large."These are also some of the oldest stars we've seen anywhere," study co-author Stefano Souza, a doctoral candidate at the University of Sao Paulo, Brazil, said in a statement. [15 Unforgettable Images of Stars]The Milky Way's bulge -- a bulbous, 10,000 light-year-wide region of stars and dust popping out of the galaxy's spiral disc -- is thought to contain some of the oldest stars in the galaxy.Previous studies have tried to prove that ancient stars were hiding in the Milky Way's bulge by studying HP1 and other nearby clusters. But Souza and his colleagues analyzed the problem with unprecedented resolution, thanks to an imaging technique called adaptive optics -- essentially, a method that corrects pictures of space for light distortions caused by Earth's atmosphere.By combining these ultra-high-definition observations and reviewing archival footage from Hubble, the team calculated the distance to Earth for even the dimmest, most dust-covered stars in HP1. These distances helped the team to calculate each star's brightness. The intensity and color of each star's light, in turn, reveals the star type -- whether it was a dwarf or a giant, for example, or whether it emitted a lot of elements heavier than hydrogen and helium.The weight of a star's elements -- also called its "metallicity" -- is crucial information for scientists who study aging celestial bodies. Researchers suspect that the universe's earliest stars formed out of primordial clouds of pure hydrogen gas. The universe's first helium atoms are thought to have emerged from the nuclear reactions at the hearts of these ancient stars.. Eventually, as more and more stars were born, every other element currently known to humans exploded into existence.Stars that produce a lot of elements heavier than hydrogen and helium are therefore considered to be relatively young in the cosmic scheme of things. So, when the Gemini researchers saw that the stars of HP1 were extremely light on heavy elements, they knew they had an old cluster in their sights.The team calculated that the stars likely date to the first billion years of the universe's life -- making them roughly 12.8 billion years old."HP 1 is one of the surviving members of the fundamental building blocks that assembled our galaxy's inner bulge," lead study author Leandro Kerber of the University of Sao Paulo and Brazil's State University of Santa Cruz,said in the statement.The fact that the Milky Way hides ancient stars in its bulging midsection means the area is the perfect location for studying our galaxy's awkward childhood years. * 5 Reasons We May Live in a Multiverse * 9 Strange, Scientific Excuses for Why We Haven't Found Aliens Yet * Gallery: Our Amazing SunOriginally published on Live Science.
