An anonymous reader writes from a report via NPR: Netflix announced this week that it has acquired the rights to stream Chinese sci-fi blockbuster "The Wandering Earth," which has already grossed more than $600 million globally and hit number two in the all-time Chinese box office rankings since it was released in theaters Feb. 5. Netflix will translate the movie into 28 languages and release it in more than 190 countries. The movie, based on a short story by Hugo award winner Liu Cixin (author of "Three Body Problem" and "Ball Lighting") is set in a distant future in which the earth is about to be devoured by the sun. Using propulsive engines, humans turn earth into a spaceship and try to launch it out of the solar system and the planet is saved by a Chinese hero (rather than American ones as typically seen in Hollywood sci-fi movies.)

For China's film industry, the release marks a major milestone. "Filmmakers in China see science fiction as a holy grail," Raymond Zhou, an independent critic, told The New York Times. "It's like the coming-of-age of the industry." Two sci-fi movies, "The Wandering Earth" and "Crazy Alien," which is also inspired by Liu's work, topped this Chinese New Year movie season. Inkoo Kang wrote at Slate that the film "understands what American blockbusters are still loath to admit: Responding to climate change will pose infrastructural challenges on a massive order and require drastic measures on a planetary scale. Perhaps it takes a country like China, which is accustomed to a manic rate of construction and grandness of organizational possibility, to seriously consider how dramatically humanity will have to reimagine our ways of life to survive such a catastrophic force."

pgmrdlm shares a report from The Independent: Medicines including antibiotics and epilepsy drugs are increasingly being found in the world's rivers at concentrations that can damage ecosystems, a study has shown. Dutch researchers developed a model for estimating concentrations of drugs in the world's fresh water systems to predict where they could cause the most harm to the food web. The study, published in Environmental Research Letters, focuses on two particular drugs: antibiotic ciprofloxacin and anti-epileptic drug carbamazepine. Between 1995 and 2015 it found that rising concentrations of the drugs and the increasing number of water tables affected meant the risks to aquatic ecosystems are 10 to 20 times higher than two decades earlier.

Carbamazepine has been linked to disrupting the development of fish eggs and shellfish digestive processes, and the study found potential risks were most pronounced in arid areas with a few major streams. The risks were much more widespread for ciprofloxacin, with 223 of 449 ecosystems tested showing a significant risk increase. More worrying still, when [the researchers] compared their predictions to samples from four river systems they found their model was underestimating the risk. Pharmaceutical residues can enter these fresh water systems through waste water from poorly maintained sewer systems, or from run-off over fields for drugs used in livestock.

An anonymous reader quotes a report from NPR: Scientists have launched a major new phase in the testing of a controversial genetically modified organism: a mosquito designed to quickly spread a genetic mutation lethal to its own species, NPR has learned. For the first time, researchers have begun large-scale releases of the engineered insects, into a high-security laboratory in Terni, Italy. The goal is to see if the mosquitoes could eventually provide a powerful new weapon to help eradicate malaria in Africa, where most cases occur. The lab was specially built to evaluate the modified insects in as close to a natural environment as possible without the risk of releasing them into the wild, about which there are deep concerns regarding unforeseen effects on the environment.

To prevent any unforeseen effects on the environment, scientists have always tried to keep genetically engineered organisms from spreading their mutations. But in this case, researchers want the modification to spread. So they engineered mosquitoes with a "gene drive." A gene drive is like a "selfish gene," says entomologist Ruth Mueller, because it doesn't follow the normal rules of genetics. Normally, traits are passed to only half of all offspring. With the gene drive, nearly all the progeny inherit the modification. Researchers created the mosquitoes by using the powerful new gene-editing technique known as CRISPR, which Mueller likens to a "molecular scissor which can cut at a specific site in the DNA." The cut altered a gene known as "doublesex," which is involved in the sexual development of the mosquitoes. While genetically female, the transformed insects have mouths that resemble male mosquito mouths. That means they can't bite and so can't spread the malaria parasite. In addition, the insects' reproductive organs are deformed, which means they can't lay eggs. As more and more female mosquitoes inherit two copies of the modification, more and more become sterile. Critics fear that these gene-drive mosquitoes could run amok and wreak havoc in the wild. Not only could the insects cause a negative effect on crops by eliminating important pollinators, but the insects' population crash could also lead to other mosquitos coming with other diseases.

Mueller assures NPR's Rob Stein that the lab the mosquitos are in is very secure, adding that even if the mosquitos did escape they would not be able to survive Italy's climate. "To enter the most secure part of the facility, Mueller punches a security code into a keypad to open a sliding glass door," reports NPR. "As the door seals, a powerful blower makes sure none of the genetically modified mosquitoes inside escape. Anyone entering must don white lab coats to make it easier to spot any mosquitoes that might try to hitch a ride out of the lab and must pass through a second sealed door and blower."

NASA and SpaceX have agreed to move forward with the first unmanned test flight of SpaceX's new passenger capsule, the Crew Dragon. It is set to launch on March 2nd out of Cape Canaveral, Florida. "If the capsule successfully makes it to orbit, SpaceX will be one crucial step closer to putting the first humans on board its spacecraft," reports The Verge. From the report: This flight, called Demonstration Mission-1, or DM-1, is a major milestone for NASA's Commercial Crew program, an initiative to send NASA astronauts to the International Space Station aboard private vehicles. Since the Shuttle program ended, NASA has relied on Russia to ferry its astronauts to and from low Earth orbit -- an expensive arrangement that limited the types of missions NASA could run. But soon, US astronauts could be launching on US-made vehicles once again, as NASA did during the Space Shuttle era.

For the program, both SpaceX and rival company Boeing, have been developing new capsules to transport NASA astronauts to and from low Earth orbit. NASA wants the two companies to send these vehicles to space first, empty, before putting people on board. Boeing's vehicle, the CST-100 Starliner, is set to fly uncrewed for the first time this April. But SpaceX's Crew Dragon has been at Cape Canaveral since December, ready to fly. SpaceX even tested out the engines on the Falcon 9 rocket it plans to use to carry the capsule to orbit. The company just needed NASA's approval to make it happen. NASA tentatively set the March 2nd date a few weeks ago, and now that the okay has been given, SpaceX is just a week away from the big flight. The capsule is set to fly at 2:48AM ET from NASA's Kennedy Space Center in Florida -- an early morning launch time dictated by the International Space Station's position in orbit. If the Crew Dragon gets off the ground then, it'll stay in orbit until early morning on Sunday and then attempt to automatically dock with the space station. It will then remain at the ISS for a week before detaching early Friday morning and returning to Earth to splash down in the Atlantic Ocean near Florida.

"Oumuamua, the first object ever seen passing through our solar system from interstellar space, was thought to be emitting gas like a comet to explain its weird motion," reports Syfy Wire, "but a new idea is that the comet is just very, very porous."

Astronomer Phil Plait writes: It was hard to tell what it was; it was too small, faint, and far away to get good observations, and worse, it was only seen on its way out, so it was farther from us literally every day. Then another very weird thing happened: More observations allowed a better determination of its trajectory, and it was found that it wasn't slowing down fast enough. As it moves away, the Sun's gravity pulls on it, slowing it down...but it wasn't slowing down enough. Some force was acting on it, accelerating it very slightly... A new paper has come out that might have a solution, and it's really clever. Maybe 'Oumuamua's not flat. Maybe it's fluffy... [And thus moved by the force of sunlight giving it a tiny push]

When stars are very young, they have a huge disk of material swirling around them; it's from this material that planets form. Out far from the star, where temperatures in the disk are cold, teeny tiny grains of dust and water ice can stick together in funny shapes, creating fractals... Materials made in a fractal pattern can be very porous, and in fact out in that protoplanetary disk around a young star, physical models show that objects can grow fractally until they're as big as 'Oumuamua, and have those extremely low densities needed to account for its weird behavior. So 'Oumuamua doesn't have to be a spaceship. It just has to be a snowflake! A three-dimensionally constructed phenomenally porous low-density snowflake... [T]he new paper suggests it came from a nearby star, and one that's relatively young (less than 100 million years). It formed out in the disk, and got ejected somehow, likely from a planet forming nearby giving it a boost from its gravity.
"I certainly hope we find more beasties like this one," Plait writes. "They can tell us so much about how planets form in other star systems, which is pretty hard to figure out from dozens or hundreds of light years away.

"It's a lot easier when they obligingly send bits of their building materials to us."

"A scientist working for the U.S. Navy has filed for a patent on a room-temperature superconductor, representing a potential paradigm shift in energy transmission and computer systems," reports Phys.org: Salvatore Cezar Pais is listed as the inventor on the Navy's patent application made public by the U.S. Patent and Trademark Office on Thursday. The application claims that a room-temperature superconductor can be built using a wire with an insulator core and an aluminum PZT (lead zirconate titanate) coating deposited by vacuum evaporation with a thickness of the London penetration depth and polarized after deposition.

An electromagnetic coil is circumferentially positioned around the coating such that when the coil is activated with a pulsed current, a non-linear vibration is induced, enabling room temperature superconductivity. "This concept enables the transmission of electrical power without any losses and exhibits optimal thermal management (no heat dissipation)," according to the patent document, "which leads to the design and development of novel energy generation and harvesting devices with enormous benefits to civilization."
Long-time Slashdot reader resistant writes: NextBigFuture says the same individual appears to have made other startling claims that arguably stretch the boundaries of belief, such as a "high-frequency gravitational wave generator" that could supposedly drive a spaceship without conventional propellants as well as an "inertial mass reduction device." Prudence would appear to dictate examining these and other claims by Mr. Salvatore Cezar Pais with great caution.

A new adsorbent material "soaks up uranium from seawater, leaving interfering ions behind," reports the ACS's Chemical & Engineering News, in an article shared by webofslime: The world's oceans contain some 4 billion metric tons of dissolved uranium. That's roughly 1,000 times as much as all known terrestrial sources combined, and enough to fuel the global nuclear power industry for centuries. But the oceans are so vast, and uranium's concentration in seawater is so low -- roughly 3 ppb -- that extracting it remains a formidable challenge... Researchers have been looking for ways to extract uranium from seawater for more than 50 years...

Nearly 20 years ago, the Japan Atomic Energy Agency (JAEA) confirmed that amidoxime-functionalized polymers could soak up uranium reliably even under harsh marine conditions. But that type of adsorbent has not been implemented on a large scale because it has a higher affinity for vanadium than uranium. Separating the two ions raises production costs. Alexander S. Ivanov of Oak Ridge National Laboratory, together with colleagues there and at Lawrence Berkeley National Laboratory and other institutions, may have come up with a solution. Using computational methods, the team identified a highly selective triazine chelator known as H2BHT that resembles iron-sequestering compounds found in bacteria and fungi.... H2BHT exhibits little attraction for vanadium but has roughly the same affinity for uranyl ions as amidoxime-based adsorbents do.

"If you're willing to spend $250,000 for a quick trip to space, that option is getting closer to reality," reports CNN. VSS Unity, Virgin Galactic's rocket-powered plane, climbed to a record altitude of nearly 56 miles during a test flight on Friday, marking the second time Richard Branson's startup has reached space. Two pilots, and for the first time, an additional crew member, were on board. Beth Moses, Galactic's chief astronaut trainer and an aerospace engineer, rode along with the pilots. The trip allowed her to run safety checks and get a first look at what Galactic's customers could one day experience. Moses has logged hundreds of hours on zero gravity aircrafts, and she described the G Forces aboard the supersonic plane as "mildly wild." Some moments were intense, she told CNN Business, but it was never uncomfortable. "I was riveted and I think our customers will be as well."

Unity took off from a runway in California's Mojave Desert just after 8 am PT and cruised to about 45,000 feet attached to its mothership before it broke away and fired its rocket motor. The plane then swooped into the upper reaches of the atmosphere, 295,000 feet high, at supersonic speeds. It's top speed was Mach 3. At the peak of its flight path, Unity experienced a few minutes of weightlessness and looked out into the black skies of the cosmos. Moses said she was able to leave her seat and take in the view. "The Earth was beautiful -- super sharp, super clear," she said, "with a gorgeous view of the Pacific mountains."
America's Federal Aviation Administration says they'll now award commercial astronaut wings to all three members of the crew, and CNN reports that this second successful test flight suggests Galactic "could be on track" to start flying tourists into space this year.

"About 600 people have reserved tickets, priced between $200,000 and $250,000, to fly with Galactic. And the company says it wants to eventually lower prices to broaden its customer base."

Japan's Hayabusa 2 spacecraft has successfully touched down on the asteroid Ryugu at around 11:30 GMT on Thursday. "Data from the probe showed changes in speed and direction, indicating it had reached the asteroid's surface, according to officials from the Japan Aerospace Exploration Agency (JAXA)," reports The Guardian. From the report: The probe was due to fire a bullet at the Ryugu asteroid, to stir up surface matter, which it will then collect for analysis back on Earth. The asteroid is thought to contain relatively large amounts of organic matter and water from some 4.6 billion years ago when the solar system was born. The complicated procedure took less time than expected and appeared to go without a hitch, said Hayabusa 2 mission manager Makoto Yoshikawa. The spacecraft is seeking to gather 10g of the dislodged debris with an instrument named the Sampler Horn that hangs from its underbelly. Whatever material is collected by the spacecraft will be stored onboard until Hayabusa 2 reaches its landing site in Woomera, South Australia, in 2020 after a journey of more than three billion miles. UPDATE: JAXA says it successfully fired a "bullet" into Ryugu, collecting the disturbed material. "JAXA scientists had expected to find a powdery surface on Ryugu, but tests showed that the asteroid is covered in larger gravel," reports CNN. "As a result the team had to carry out a simulation to test whether the projectile would be capable of disturbing enough material to be collected by [the Sampler Horn]. The team is planning a total of three sampling events over the next few weeks."

An anonymous reader quotes a report from Phys.Org: JILA researchers have made a long-lived, record-cold gas of molecules that follow the wave patterns of quantum mechanics instead of the strictly particle nature of ordinary classical physics. The creation of this gas boosts the odds for advances in fields such as designer chemistry and quantum computing. As featured on the cover of the Feb. 22 issue of Science, the team produced a gas of potassium-rubidium (KRb) molecules at temperatures as low as 50 nanokelvin (nK). That's 50 billionths of a Kelvin, or just a smidge above absolute zero, the lowest theoretically possible temperature. The molecules are in the lowest-possible energy states, making up what is known as a degenerate Fermi gas.

In a quantum gas, all of the molecules' properties are restricted to specific values, or quantized, like rungs on a ladder or notes on a musical scale. Chilling the gas to the lowest temperatures gives researchers maximum control over the molecules. The two atoms involved are in different classes: Potassium is a fermion (with an odd number of subatomic components called protons and neutrons) and rubidium is a boson (with an even number of subatomic components). The resulting molecules have a Fermi character. Before now, the coldest two-atom molecules were produced in maximum numbers of tens of thousands and at temperatures no lower than a few hundred nanoKelvin. JILA's latest gas temperature record is much lower than (about one-third of) the level where quantum effects start to take over from classical effects, and the molecules last for a few seconds -- remarkable longevity. These new ultra-low temperatures will enable researchers to compare chemical reactions in quantum versus classical environments and study how electric fields affect the polar interactions, since these newly created molecules have a positive electric charge at the rubidium atom and a negative charge at the potassium atom. Some practical benefits could include new chemical processes, new methods for quantum computing using charged molecules as quantum bits, and new precision measurement tools such as molecular clocks.

pgmrdlm writes: Cooking a Sunday roast can drive indoor air pollution far above the levels found in the most polluted cities on Earth, scientists have said. Researchers found that roasting meat and vegetables, and using a gas hob, released a surge of fine particles that could make household air dirtier than that in Delhi. Fine soot and tiny organic particles from gas flames, vegetables, oils and fat combined to send harmful PM2.5 particulates in the house to levels 13 times higher than those measured in the air in central London. Peak indoor pollution lasted for about an hour.

"We were all surprised at the overall levels of particulate matter in the house," said Marina Vance, who led the research at the University of Colorado in Boulder. She advised people to open windows and use extractor hoods if possible to ventilate the home while cooking. PM2.5s are particles that are smaller than 2.5 micrometres across. They are small enough to be inhaled deep into the lungs where they exacerbate respiratory disorders and cardiovascular disease. Smaller particles can spread from the lungs into the bloodstream where they build up in the liver, heart and even the brain, where they may contribute to depression and other mental health issues.

The first privately funded mission to land on the moon took one giant step forward this evening as an Israeli spacecraft blasted off from Cape Canaveral, Florida. "[I]f the mission is successful, it would make Israel the fourth country to land a spacecraft on the lunar surface -- after the U.S., the former Soviet Union and China," reports NPR. From the report: The spacecraft launched with a Space X Falcon 9 rocket, according to SpaceIL's partner Israel Aerospace Industries. It detached from the reusable rocket, which returned to an off-shore platform. The spacecraft was to make several orbits around Earth, slowly getting closer to the moon. In a difficult maneuver, it was to pivot from orbiting Earth to orbiting the moon, and then eventually attempt a treacherous landing on the moon. The total journey will take several months, with a landing anticipated in mid-April. According to IAI, it would be the "longest journey until landing on the moon, 6.5 million kilometers."

[The spacecraft, which is called Beresheet (Hebrew for "in the beginning"] is covered in gold-colored reflective coating. And as WMFE's Brendan Byrne reported, it's about the size of a kitchen table. It's carrying a digital time capsule which, according to The Jerusalem Post, contains "drawings by Israeli children, the Bible, the national anthem, prayers, Israeli songs and a map of the State of Israel, among other cultural items." The spacecraft is set to run experiments on the moon's surface -- in particular, SpaceIL says it will collaborate with the Weizmann Institute of Science and UCLA to "take measurements of the Moon's mysterious magnetic field."

An anonymous reader quotes a report from MIT Technology Review: The brains of two genetically-edited girls born in China last year may have been changed in ways that enhance cognition and memory, scientists say. The twins, called Lulu and Nana, were modified using CRISPR, a new gene-editing tool, by a Chinese scientific team to make the girls immune to infection by HIV, the virus that causes AIDS. Now, new research shows the same genetic alteration introduced into the girls' DNA, to a gene called CCR5, not only makes mice smarter, but also improves human brain recovery after stroke, and could be linked to greater success in school.

"The answer is likely yes, it did affect their brains," says Alcino J. Silva, a neurobiologist at the University of California, Los Angeles. Silva's lab lab has been uncovering a major new role for the CCR5 gene in memory formation and the brain's ability to form new connections. "The simplest interpretation is that those mutations will probably have an impact on cognitive function in the twins," says Silva. He says the exact effect on the girls cognition is impossible to predict and "that is why it should not be done." The Chinese designer babies were created to be resistant to HIV. A team in Shenzhen, China, led by Southern University of Science and Technology He Jiankui used the gene-editing tool CRISPR to delete a single gene, called CCR5, from human embryos, some of which were later used to create pregnancies. The virus that causes AIDS requires the CCR5 gene to enter human blood cells. The scientist, He Jiankui of the Southern University of Science and Technology in Shenzhen, China, has been fired from the university as He is under investigation in China. There is no evidence that He actually set out to modify the twins' intelligence.

Contrary to general belief that Earth's atmosphere stops a bit over 62 miles from the surface, a new study based on observations made over two decades ago by the joint US-European Solar and Heliospheric Observatory (SOHO) satellite shows that it actually extends as far 391,000 miles (630,000 km) or 50 times the Earth's diameter. This makes the Moon a very high altitude aircraft. From a report: Launched on December 2, 1995 atop an Atlas IIAS launcher from Cape Canaveral Air Force Station in Florida, SOHO is parked in the first Lagrange point (L1) 930,000 miles (1.5 million km) from Earth where it has carried out studies of the Sun and the solar winds, and will continue to do so until at least 2020. From this vantage point, the observatory's Solar Wind Anisotropie (SWAN) instrument is able to measure the presence of hydrogen by looking at the Lyman-alpha line in the solar spectrum. And what works for the Sun, works for Earth. By turning SWAN on the Earth at the right times of the year, SOHO was able to detect hydrogen atoms from the atmosphere and measure how far out they extend into what space scientists call the geocorona. While the existence of the geocorona is well known -- the telescope set up by the Apollo 16 astronauts on the Moon even photographed it -- no one was sure how far out it reaches until now.

By looking at data collected by SOHO in the mid 1990s, scientists from Russia's Space Research Institute and elsewhere were able to work out the extent and density of the geocorona. What they found was that sunlight on the day side of the Earth compresses the hydrogen until it reaches a density of 70 atoms per cubic cm at an altitude of 37,000 miles (60,000 km), and on the night side it can expand out until it has a density of only 0.2 atoms per cubic cm at the distance of the Moon's orbit. According to the study leader Igor Baliukin, the geocorona is so tenuous that it poses no hazard to astronauts or spacecraft.

Why do zebras have stripes? From a report: Evolutionary biologists have proposed many possible theories, such as camouflage or vision aids for recognizing individual zebras. But in recent years, pest control has emerged as the leading explanation for zebra stripes. Researchers led by Tim Caro, an evolutionary ecologist at UC Davis, set out to test this idea in the field. The results, published Wednesday in PLOS ONE, reveal that stripes are a powerful deterrent to horse flies, a common nuisance that suck blood and bite flesh. The experiment managed to find the most delightful way to help explain these uniquely patterned coats -- by getting horses to cosplay as zebras.

An anonymous reader quotes a report from Ars Technica: The legislator in question is Republican Joe Read, who represents an area north of Missoula, home of many fine scientists at the University of Montana. Read has eight bills under consideration in the current session of the legislature, and two of those focus on climate change. One of them focuses on his state's role in any greenhouse gas regulatory program that would be instituted under a future president. Read is apparently unaware of past legal precedent indicating that the federal government has the legal ability to regulate pollutants. Instead, the preamble of the bill seemingly argues that Montana's emissions are all due to commerce that takes place within the state, and thus "any federal greenhouse gas regulatory program in the form of law or rule violates the 10th Amendment of the Constitution of the United States."

As a result, the bill would prohibit state agencies, officials, and employees from doing anything to cooperate with federal efforts to limit greenhouse gas emissions. If passed, the Montana government "may not implement or enforce in any way any federal regulation, rule, or policy implementing a federal greenhouse gas regulatory program." But if you thought Read's grasp of constitutional law was shaky, you should check out his reason for objecting to doing anything about climate change. That's laid out in his second bill, which targets both science education and in-state programs designed to reduce carbon emissions. And it doesn't mince words, suggesting that pretty much all the scientists have it wrong: "the [US] National Climate Assessment makes the same errors as the Intergovernmental Panel on Climate Change, and the National Academy of Sciences is also fundamentally wrong about climate change."

NASA is keeping an eye on the Brunt Ice Shelf, home to the British Antarctic Survey's Halley VI Research Station, which has growing cracks that are threatening to unload an iceberg soon. "NASA/USGS Landsat satellites are monitoring the action as the cracks grow," reports CNET. "When the iceberg calves, it could be twice the size of New York City. That would make it the largest berg to break off the Brunt ice shelf since observations of the area began in 1915." From the report: An annotated view of the ice shelf shows the cracks as they relate to the Halley VI station. The crack leading up the middle is especially concerning. It's been stable for 35 years, but NASA says it's now extending northward as fast as 2.5 miles (4 kilometers) per year. As of December, Halley station was home to around 30 science and technical staff on missions to study the ice shelf and climate change in the polar region. The BAS completed a relocation of the futuristic-looking Halley station in 2017, placing it farther away from the unpredictable cracking. "It is not yet clear how the remaining ice shelf will respond following the break, posing an uncertain future for scientific infrastructure and a human presence on the shelf that was first established in 1955," NASA says. NASA says iceberg calving is "a normal part of the life cycle of ice shelves, but the recent changes are unfamiliar in this area."

An anonymous reader quotes a report from The Guardian: A team of Israeli scientists is to launch what will be the first privately funded mission to land on the moon this week, sending a spacecraft to collect data from the lunar surface. Named Beresheet, the Hebrew word for Genesis, the 585kg (1,290lb) robotic lander will blast off from Florida at 01.45 GMT on Friday, propelled by one of Elon Musk's SpaceX Falcon 9 rockets. Once it touches down, in several weeks, it will measure the magnetic field of the moon to help understand how it formed. Beresheet will also deposit a "time capsule" of digital files the size of coins containing the Bible, children's drawings, Israel's national anthem and blue and white flag, as well as memories of a Holocaust survivor. While it is not a government-led initiative, the state-owned Israel Aerospace Industries (IAI) corporation joined as a partner. If the mission is successful, Israel will become the fourth country, after Russia, the U.S. and China, to reach the moon. "This is the lowest-budget spacecraft to ever undertake such a mission," an IAI statement said of the $100 million project. "The superpowers who managed to land a spacecraft on the moon have spent hundreds of millions." It added that although it was a private venture, Beresheet was a "national and historic achievement."

technology_dude writes: One by one, thresholds are being crossed where the collection and storage of personal data is accepted as routine. Being recorded by cameras at business locations, in public transportation, in schools, churches, and every other place imaginable. Recent headlines include "Singapore Airlines having cameras built into the seat back of personal entertainment systems," and "Arizona considering a bill to force some public workers to give up DNA samples (and even pay for it)." It seems to be a daily occurrence where we have crossed another line in how far we will go to accept massive surveillance as normal. Do we even have a line the sand that we would defend? Do we even see anything wrong with it? Absolute power corrupts absolutely and we continue to give knowledge of our personal lives (power) to others. If we continue down the same path, I suppose we deserve what we get? I want to shout "Stop the train, I want off!" but I fear my plea would be ignored. So who out there is more optimistic than I and can recommend some reading that will give me hope? Bill 1475 was introduced by Republican State Senator David Livingston and would require teachers, police officers, child day care workers, and many others to submit their DNA samples along with fingerprints to be stored in a database maintained by the Department of Public Safety. "While the database would be prohibited from storing criminal or medical records alongside the DNA samples, it would require the samples be accompanied by the person's name, Social Security number, date of birth and last known address," reports Gizmodo. "The living will be required to pay [a $250 processing fee] for this invasion of their privacy, but any dead body that comes through a county medical examiner's office would also be fair game to be entered into the database."

Scientists think they've identified a previously unknown form of neural communication that self-propagates across brain tissue, and can leap wirelessly from neurons in one section of brain tissue to another -- even if they've been surgically severed. The discovery offers some radical new insights about the way neurons might be talking to one another, via a mysterious process unrelated to conventionally understood mechanisms, such as synaptic transmission, axonal transport, and gap junction connections. ScienceAlert reports: "We don't know yet the 'So what?' part of this discovery entirely," says neural and biomedical engineer Dominique Durand from Case Western Reserve University. "But we do know that this seems to be an entirely new form of communication in the brain, so we are very excited about this." To that end, Durand and his team investigated slow periodic activity in vitro, studying the brain waves in This neural activity can actually be modulated - strengthened or blocked - by applying weak electrical fields and could be an analogue form of another cell communication method, called ephaptic coupling.

The team's most radical finding was that these electrical fields can activate neurons through a complete gap in severed brain tissue, when the two pieces remain in close physical proximity. slices extracted from decapitated mice. What they found was that slow periodic activity can generate electric fields which in turn activate neighboring cells, constituting a form of neural communication without chemical synaptic transmission or gap junctions. "To ensure that the slice was completely cut, the two pieces of tissue were separated and then rejoined while a clear gap was observed under the surgical microscope," the authors explain in their paper. "The slow hippocampal periodic activity could indeed generate an event on the other side of a complete cut through the whole slice." The findings are reported in The Journal of Physiology.
