first_imgA rock used as a signature for the rise of oxygen in the early earth turns out to be misleading and useless for dating.Hematite in banded iron formations (BIFs) from Australia have been used for years as a marker for when the early earth saw a rise in oxygen in the sea.  Supposedly, iron first began to be oxidized when these rocks were made.  Piled on top of that assumption have been stories of the evolution of eukaryotes and photosynthesis 2.5 billion years ago, a key milestone in the progress of evolution.  Now, that marker has been criticized as misleading.In a paper in the Bulletin of the Geological Society of America, three geologists took another look at the BIFs and realized that the oxidation could have occurred much later.  “The observation that at least some of the hematite in unmineralized BIF did not form directly from ferric oxyhydroxides implies that hematite is not a reliable proxy for the composition of the precursor sediment or the redox [reduction-oxidation] chemistry of the ocean,” they concluded.Richard A. Kerr took note of this development in Science Magazine:Geologists say the study raises serious questions about a supposedly reliable test. “People are recognizing that we have to be more careful,” says geochemist Timothy Lyons of the University of California, Riverside. “We need to increasingly focus on doing just what [these authors] did, a more careful characterization of samples.”This raises the question of what motivated the earlier scientists to be careless.  Kerr pointed out that evolutionary geologists had divined the rise of oxygen from these rocks for decades.  “The ruddy mineral was thought to record the moment when photosynthesis first pushed oxygen to levels high enough to fully oxidize iron,” he said.Let this be a warning to theistic evolutionists and other old-earthers who trust the interpretations of proxy measurements for their theories, believing that the earth maintains an incontrovertible, unbiased record of its history.  If you listen to these evolutionists, ashamed as they were about trusting an unreliable method, they ended up merely replace one fallible interpretation with another.  Now they think the BIFs record another imaginary date 300 million years later, “after tectonic forces crumpled the sea floor into mountains and drove oxygen-laden water down into the rock.”  Anybody there to see that happen?  Of course not.  If reporters and other scientists leaned on a smoldering reed for decades, why should anybody lean on their next smoldering reed?  In another few decades its assumptions are likely to be overturned again.  Like Ken Ham tried to get Bill Nye to realize, there’s a big difference between looking at hematite in a rock in the present (operational science) and trying to figure out how it got that way in the past (origin science).  Nothing about bands of iron in a rock requires the moyboy story.

first_imgRavi ShastriNewly-appointed director of the Indian cricket team Ravi Shastri refuted suggestions that his role would undermine the position of beleaguered coach Duncan Fletcher.Shastri was appointed Team Director after India were defeated in the fifth and final Test against England in under three days and lost the five-Test series 1-3.”My role is to oversee everything. All of them report to me. This is for the ODI series in England,” Shastri told ‘ESPNCricinfo’.Asked if his position would affect Fletcher’s stature, Shastri said, “Absolutely not. He stays as the head coach. And these two (Sanjay Bangar and B Arun) will be his assistants.”Shastri said he took up this assignment as he wanted to contribute to the team.”It was an important time in Indian cricket. When asked I thought about it and then said, ‘fine’. The state of Indian cricket is such that I know I can contribute. I have never been scared about how tough the job is or how easy the job is.”The important thing is the contribution.”If I am here today, and at times some forget, it is because of the BCCI. The platform they gave me when I was a junior cricketer to play for my state and then the country,” he said.On whether he has had a word with skipper Mahendra Singh Dhoni and Fletcher after his appointment, Shastri said, “I spent about two hours with them (on Tuesday). We had a chat about where things are at the moment, how things have to be addressed, and how important communication will be.”advertisementAsked what he felt were the reasons for India’s failure in the Test series, Shastri said it was inexperience.”If you calculate the number of Test matches played by the XI as opposed to some of the tours where we fared worse, here we at least won a Test match.””We did not win a Test in 1974 (3-0) and were whitewashed on the last tour here with some of the biggest names (in the team). So if you calculate the number of Test caps between this unit and some of the other units that have come (in the past), it is chalk and cheese,” he explained.”On this tour I saw India’s greatest ever overseas win I have seen. I know it because I have never seen a track like that and with this kind of inexperienced side for them to pull it off. Then I also saw some spineless cricket over the last three Tests matches.”last_img read more

He’s accumulated 538 rushing and receiving yards in three starts for the Kansas City Chiefs, with a fourth game tonight against Washington on Monday Night Football. Of the 812 rookies who have racked up more than 100 yards in their first three games, Hunt sits behind only Billy Simms, who put up 562 yards for Detroit in 1980. [FiveThirtyEight]Niners (D-CA) vs. Bucs (R-FL)The NFL has been a nexus recently for protests, particularly last weekend after some goading from the president on Twitter. This sent league executives into a crisis, and it’s clear why: The NFL appeals to people across party lines in a way few other sports do, with fans in San Francisco (who have a +22 point Democratic lean) to Tampa Bay (a +9.5 Republican lean). [FiveThirtyEight]MLB teams waffle on jumping lowest possible bar for safetyA devastating line drive foul that severely injured a child has spurred league-wide introspection about how much netting should protect spectators from baseballs. People in luxury boxes hate mildly obstructed views, but also baseballs can be dangerous projectiles as seen in New York last month. Only 10 of 30 teams have netting that goes to the end of the dugouts. At least four teams have announced they will extend the netting in the wake of the injured 2-year-old in Yankee Stadium.

In layman’s terms, the Nets have essentially adopted the same offensive principles as the analytically friendly Houston Rockets, coached by Atkinson mentor Mike D’Antoni. (Fitting that these clubs combined for an NBA-record 106 3-point attempts in a game last week.) Russell, who leads starting ball-handlers with 61.5 pick and rolls per 100 plays, will run you around screens all day, and he and his Brooklyn teammates generally avoid midrange shots, instead probing for much higher-percentage looks. No NBA team has driven to the basket more than the Nets, and this would mark the third consecutive season that Brooklyn ranks in the top 10 in free-throw rate.Defensively, the story is much the same. The Nets have excelled at forcing opponents to walk the analytics plank, ranking among the top five in 2016-17, 2017-18 and again this season in terms of how often they coax teams into longer midrange 2-pointers. When teams are fortunate enough to get to the basket, they’re often met by 20-year-old Jarrett Allen, a big man who has erased some of the game’s biggest names at the rim while sometimes playing a one-man zone. The Nets also rank near the top of the NBA in boxing out, to finish those defensive possessions.That combination — continuing to take the most efficient shots possible on offense while taking those same shots away on the other end — has been the NBA equivalent of Andy Dufresne’s rock hammer in “The Shawshank Redemption.” The team’s strategy and talent, combined with its newfound maturation in the clutch, have finally set it free.Brooklyn basically looked shackled at the ends of games last year and at the start of this season. Whether it was inexperience, consistently bad whistles or a combination of the two, the Nets were managing to find new, devastating ways to lose close contests each night.But even that’s changed of late. The Nets, who were a dismal 4-10 in clutch situations as of Dec. 1, have since gone 11-4 in those same scenarios.One noteworthy shift there is rooted in Russell and Dinwiddie’s ability to coexist during the hot streak — something that had consistently backfired from a net-rating standpoint over the past two seasons. (Their ability to play together, or lack thereof, will be worth watching because of the decision the Nets have to make about the future of Russell, who’s a restricted free agent this summer. Yet it looks like Russell will have the show to himself, as Dinwiddie, who just signed a three-year, $34 million extension, could miss considerable time with a torn ligament in his thumb.) But other elements also stand out. Joe Harris is one of the NBA’s best perimeter shooters. Latvian forward Rodions Kurucs was a great find and is a fluid scorer at 6-foot-9.While the Nets are clearly ascending, they still have their issues, too.Brooklyn has one of the highest turnover rates in the league. The Nets can occasionally find themselves with matchup problems against teams with floor-spacing bigs because of how Allen anchors himself to the paint on defense. The lack of pressure on pick-and-roll ball-handlers hurts their ability to force turnovers. For how well the team gets to the stripe, Russell, its leading scorer, takes fewer free throws than any other volume shooter in the NBA.1This includes any player taking at least 15 field-goal attempts per game. Injuries have nagged Brooklyn all year, and while it’s fair to expect a boost from players if and when they return — especially from LeVert — key players’ roles may have to shrink to accommodate everyone once they’re back. And the Nets, who have enjoyed one of the easiest slates so far, will be thoroughly tested by their upcoming schedule — especially from mid-March to the end of the season.There’s a reason we hear so much about the Nets eventually landing a player like Kevin Durant, Kawhi Leonard or Jimmy Butler. Aside from the fact that they’re one of few big-market teams that seemingly has a direction, a blank-enough canvas (in terms of not having a star) and cap space to make something happen, they also would become an instant contender by adding someone of that caliber. Again, the decision on Russell could complicate that. Yet the reality is that getting past the second round likely requires more than this current cast, even at full strength.For the time being, though, it has been eye-opening to watch the 22-year-old Russell play this well since the turn of the new year, a span in which he’s averaged 24 points and nearly eight assists on 49 percent shooting from the floor, along with his rainbow-arc triples falling at a 44 percent clip.While he’ll never possess the sort of bounce that some of his counterparts have, the former No. 2 overall pick has leveraged the threat of his pull-up jumper into being able to beat defenders to certain spots. When he senses defenders on his hip, he’ll often make use of ball fakes to buy himself more space before shooting.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2019/01/Russell.mp400:0000:0001:22Use Up/Down Arrow keys to increase or decrease volume.He’s been more consistent with the ball during that window, too, passing teammates open while logging a 3-to-1 assist-to-turnover ratio in 2019 — up from 2-to-1 earlier this season and much better than his career ratio of 1.5-to-1 coming into the 2018-19 campaign.Certain elements of Russell’s offensive run lately, much like the team’s overall, are going to come back down to earth at some point. But with how hellish things have been in Brooklyn for much of the past five years, and with how sound the team’s strategy has been in digging out of that trench, Russell, the Nets and their fans all have ample reason to be enjoying this — even if they aren’t exactly sure what comes next.Check out our latest NBA predictions. For more than four years, the Brooklyn Nets had been more or less irrelevant on a national scale. Whenever the team came up in a larger conversation, it was usually to discuss how one of its first-round picks — dealt in that infamous trade for Kevin Garnett and Paul Pierce — was benefiting another franchise that got to reap the draft payoff. You have to go back to 2013-14, a full season after the Nets left New Jersey for Brooklyn, to find the last time they finished .500.All of which makes the Nets — winners of five straight and co-owners of the NBA’s best record over the past month and a half — so compelling. At 26-23, the team is currently holding a playoff position in sixth place in the East. Coach Kenny Atkinson, again, is finding enormous success with his point guards, including D’Angelo Russell, who’s in contention for an All-Star spot. And the club, which in early December was mired in an eight-game skid and couldn’t hold late-game leads, is all of a sudden unbeatable in the clutch. And this is after Brooklyn lost perhaps its best all-around player, Caris LeVert, to a brutal long-term injury.But underneath all that past losing — and there was a lot of it, given that this team has had three consecutive seasons with fewer than 30 wins — there were several road signs that the Nets were tapping into an array of good strategies to begin a turnaround.Much of that was rooted in ideology and experimentation, necessities because of how bare the draft-pick cupboard was for a while. The team had to take some creative steps (read: accept salary dumps) in a bid to get some talent on its roster. And the club’s front office, led by Sean Marks, had to identify talent that was being ignored or undervalued, like guard Spencer Dinwiddie, and trust its own ability to help develop players like him into everyday rotation pieces.The hiring of Atkinson, a longtime NBA assistant, was a key catalyst. Well before the wins started outnumbering the losses, and before there was enough talent to expect playoff berths, the 51-year-old quickly began changing the team’s shot profile on both ends of the floor.During the 2015-16 campaign, a year before he came on, the Nets ranked 26th out of 30 in quantified Shot Quality, which measures the likelihood of shots going in, if taken by an average NBA player, according to stat database Second Spectrum. The club completely overhauled that at the start of Atkinson’s tenure, though, as Brooklyn finished fifth and fourth in 2016-17 and 2017-18, respectively. And this season, the Nets rank ninth in the metric. read more


Reviewed by James Ives, M.Psych. (Editor)Dec 18 2018A federal court ordered a Michigan-based food manufacturer to discontinue selling food products until the company complies with federal regulations and other requirements. This action follows several inspections conducted by the U.S. Food and Drug Administration and Michigan Department of Agriculture and Rural Development, which found Listeria monocytogenes (L. mono) in the company’s food preparation area.U.S. District Judge Paul L. Maloney for the Western District of Michigan entered a consent decree of permanent injunction on Nov. 30, 2018, between the U.S. and Saranac Brand Foods, and the company’s co-owners, Dennis M. Nowak and Daniel R. Nowak. Saranac Brand Foods specialized in manufacturing a variety of 35 different ready-to-eat foods including prepared salads, dips and sauces.The consent decree prohibits the defendants from receiving, preparing, processing, packing, holding, labeling and/or distributing foods at or from their facility, or any other facility, until certain requirements are met. The defendants told the court they discontinued all food operations in August 2018 and intend to dissolve the company. If the defendants choose to resume operations, the consent decree requires them to notify the FDA and take corrective actions before resuming operations.”The FDA and the Michigan Department of Agriculture and Rural Development have documented a pattern of food safety violations at this facility. The inappropriate and unsafe practices of Saranac Brand Foods. not only violated the law, but also put consumers in harm’s way,” said FDA Associate Commissioner for Regulatory Affairs Melinda Plaisier. “This type of behavior is unacceptable to the FDA and is why we took action to prevent the defendants from introducing contaminated or potentially contaminated food products into the marketplace.”Related StoriesLean manufacturing methods spur innovations in the testing of drug delivery devicesNew personalized prosthetic liners could help more amputees walk againResearchers improve training modules for future surgeons with 3D printingAccording to the complaint, filed by the U.S. Department of Justice on behalf of the FDA, FDA and state officials inspected the facility several times since 2012 and found L. mono in the facility during three separate inspections. The inspections also documented that the defendants were processing food under insanitary conditions, in violation of the Federal Food, Drug, and Cosmetic Act (FD&C Act). L. mono is a pathogenic bacterium that can cause listeriosis, a rare but potentially life-threatening illness. People with compromised immune systems, the elderly, pregnant women and developing fetuses are particularly susceptible to listeriosis.In August 2016, the FDA issued the defendants a Warning Letter, informing them of the L. mono contamination and objectionable conditions at the facility. The Warning Letter emphasized the serious nature of the deficiencies and stated that it was the defendants’ responsibility to ensure that their products comply with the FD&C Act. In November 2017, the FDA’s investigators issued the defendants a list of inspectional observations that identified insanitary conditions observed during a follow-up inspection.Consumers are encouraged to contact the FDA to report problems with any FDA-regulated products.The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices.
