An anonymous reader quotes a report from ScienceDaily: In a University of California, Irvine-led study, researchers found evidence that fasting affects circadian clocks in the liver and skeletal muscle, causing them to rewire their metabolism, which can ultimately lead to improved health and protection against aging-associated diseases. The study was published recently in Cell Reports. The research was conducted using mice, which were subjected to 24-hour periods of fasting. While fasting, researchers noted the mice exhibited a reduction in oxygen consumption (VO2), respiratory exchange ratio (RER), and energy expenditure, all of which were completely abolished by refeeding, which parallels results observed in humans.
"The reorganization of gene regulation by fasting could prime the genome to a more permissive state to anticipate upcoming food intake and thereby drive a new rhythmic cycle of gene expression. In other words, fasting is able to essentially reprogram a variety of cellular responses. Therefore, optimal fasting in a timed manner would be strategic to positively affect cellular functions and ultimately benefiting health and protecting against aging-associated diseases." This study opens new avenues of investigation that could ultimately lead to the development of nutritional strategies to improve health in humans.Read Replies (0)

Yesterday, the Key West City Commission unanimously voted to ban the sale of sunscreens that contain two ingredients -- oxybenzone and octinoxate -- that a growing body of scientific evidence says harm coral reefs. The measure must now be reviewed again by the commission before it becomes law. The second vote is scheduled for February 5th. Miami Herald reports: Environmental researchers have published studies showing how these two ingredients, which accumulate in the water from bathers or from wastewater discharges, can damage coral reefs through bleaching and harming the corals' DNA. In some instances, the corals can die. A Feburary 2016 study in the Archives of Environmental Contamination and Toxicology examining the impact of oxybenzone in corals in Hawaii and the U.S. Virgin Islands concluded that the sunscreen ingredient "poses a hazard to coral reef conservation and threatens the resiliency of coral reefs to climate change.''
Last year, Hawaii banned the sale or distribution of any sunscreens containing oxybenzone and octinoxate, a measure that will go into effect on Jan. 1, 2021. It was the first state in the nation to implement such a ban. In Florida, the website for the South Florida Reef Ambassador Initiative, which falls under the state's Department of Environmental Protection, tells divers to "Avoid sunscreens with Oxybenzone and Avobenzone. The benzones are compounds that are lethal to coral reproduction in very small amounts." Experts who have studied the issue say sunscreens with zinc oxide or titanium dioxide, which are minerals, also block ultraviolet rays. They create a barrier on the skin that deflect the sun's rays .Read Replies (0)

"Researchers from the University of Houston have reported a new theory in physics called stress localization, which they used to tune and predict the properties of new materials," reports Phys.Org. "Based on those predictions, the researchers reported in Materials Horizons that they have created a durable silicone polymer coating capable of repelling ice from any surface." The new research has huge implications for aircraft, power transmission lines, and more. From the report: Hadi Ghasemi, Bill D. Cook Assistant Professor of mechanical engineering at UH and corresponding author for the work, said the findings suggest a way to take trial and error out of the search for new materials, in keeping with the movement of materials science toward a physics-driven approach. "You put in the properties you want, and the principle will tell you what material you need to synthesize," he said, noting that the concept can also be used to predict materials with superb antibacterial or other desirable properties.
The new material uses elastic energy localization where ice meets the material, triggering cracks at the interface that slough off the ice. Ghasemi said it requires minimal force to cause the cracks; the flow of air over the surface of an airplane acts as a trigger, for example. The material, which is applied as a spray, can be used on any surface, and Ghasemi said testing showed it is not only mechanically durable and unaffected by ultraviolet rays -- important for aircraft which face constant sun exposure -- but also does not change the aircraft's aerodynamic performance. Testing indicates it will last for more than 10 years, with no need to reapply, he said.Read Replies (0)

Researchers at cybersecurity firm Check Point say three vulnerabilities chained together could have allowed hackers to take control of any of Fortnite's 200 million players. "The flaws, if exploited, would have stolen the account access token set on the gamer's device once they entered their password," reports TechCrunch. "Once stolen, that token could be used to impersonate the gamer and log in as if they were the account holder, without needing their password." From the report: The researchers say that the flaw lies in how Epic Games, the maker of Fortnite, handles login requests. Researchers said they could send any user a crafted link that appears to come from Epic Games' own domain and steal an access token needed to break into an account.
Here's how it works: The user clicks on a link, which points to an epicgames.com subdomain, which the hacker embeds a link to malicious code on their own server by exploiting a cross-site weakness in the subdomain. Once the malicious script loads, unbeknownst to the Fortnite player, it steals their account token and sends it back to the hacker. "If the victim user is not logged into the game, he or she would have to log in first," a researcher said. "Once that person is logged in, the account can be stolen." Epic Games has since fixed the vulnerability.Read Replies (0)

An anonymous reader quotes a report from Fortune: Senator Marco Rubio (R-Fla.) introduced a bill Wednesday aimed at creating federal standards of privacy protection for major internet companies like Facebook, Amazon, and Google. The bill, titled the American Data Dissemination Act, requires the Federal Trade Commission to make suggestions for regulation based on the Privacy Act of 1974. Congress would then have to pass legislation within two years, or the FTC will gain the power to write the rules itself (under current laws, the FTC can only enforce existing rules). While Rubio's bill is intended to reign in the data collection and dissemination of companies like Facebook, Amazon, Apple, Google, and Netflix, it also requires any final legislation to protect small businesses from being stifled by new rules. The caveat comes when one considers states' rights to create their own privacy laws. Under Rubio's legislation, any national regulations would preempt state laws -- even if the state's are more strict. "While we may have disagreements on the best path forward, no one believes a privacy law that only bolsters the largest companies with the resources to comply and stifles our start-up marketplace is the right approach," Rubio wrote in an op-ed for The Hill, announcing his bill.Read Replies (0)

pgmrdlm quotes a report from CBS News: For the first time, a new network of satellites will soon be able to track all commercial airplanes in real time, anywhere on the planet. Currently, planes are largely tracked by radar on the ground, which doesn't work over much of the world's oceans. The final 10 satellites were launched Friday to wrap up the $3 billion effort to replace 66 aging communication satellites, reports CBS News' Kris Van Cleave, who got an early look at the new technology. On any given day, 43,000 planes are in the sky in America alone. When these planes take off, they are tracked by radar and are equipped with a GPS transponder. All commercial flights operating in the U.S. and Europe have to have them by 2020. It's that transponder that talks to these new satellites, making it possible to know exactly where more than 10,000 flights currently flying are.Read Replies (0)

In the era of AI superpowers, Finland is no match for the US and China. So the Scandinavian country is taking a different tack. From a report: It has embarked on an ambitious challenge to teach the basics of AI to 1% of its population, or 55,000 people. Once it reaches that goal, it plans to go further, increasing the share of the population with AI know-how. The scheme is all part of a greater effort to establish Finland as a leader in applying and using the technology.
Citizens take an online course that is specifically designed for non-technology experts with no programming experience. The government is now rolling it out nationally. As of mid-December, more than 10,500 people, including at least 4,000 outside of Finland's borders, had graduated from the course. More than 250 companies have also pledged to train part or all of their workforce.Read Replies (0)

The iconic Motorola RAZR might be making a comeback as a $1,500 foldable screen smartphone, and it could launch as early as February, according to a new report from The Wall Street Journal. From a report: The price point puts the handset north of even Apple and Samsung's flagships, at $1,500. Of course, there isn't really a standardized price point for the emerging foldables category yet. The Royole FlexPai starts at around $1,300 -- not cheap, especially for a product from a relative unknown. And Samsung, the next on the list to embrace the foldable, has never been afraid to hit a premium price point. Ultimately, $1,500 could well be standard for these sorts of products. Whether or not consumers are willing to pay that, however, is another question entirely.Read Replies (0)
