Did Martians Win the War of the Worlds?

first_imgIn the H.G. Wells version, the Martian invaders with their tripod machines and death rays, wreaking havoc on Earth, were defeated by Earth bacteria.  The new scientific plot envisioned by scientists, reported on Space.com, is that the Martians had the bacteria, and invaded Earth with it to either conquer Earth life or spread it onto our lifeless world.  Or was it the other way around?“We know very little about the origin of life on the Earth… how it happened, what kind of environment it might have happened in, and how long it look to go from the origin to the last common ancestor of life as we know it – a very complex organism very much like modern life,” [Carrine] Blank [Washington U in St. Louis] said.    Casting her eye back on Mars, Blank also said an unknown is whether conditions on early Mars were similar to what they were like on the early Earth when the origin of life likely happened.    “If they were similar, then perhaps a ‘second genesis’ could have been possible on Mars.  Even if conditions were different on Mars, there could still have been a second genesis only with a very different result than what happened on the Earth,” Blank stated.  “If these different life forms were spread throughout the solar system, then they might have co-existed if they could learn to depend upon each other.  If, on the other hand, they were in direct competition for resources, then you might expect that one would ‘win’ and survive, and the other go extinct,” she advised.So maybe the Martians won the war of the worlds.  Jack Farmer, an astrobiologist at Arizona State at Tempe, thinks the “War of the Worlds” scenario is a “serious possibility.”  Reporter Leonard David relayed some questions that raises in Farmer’s mind: “Who would win?  Is there the possibility for a competitive co-existence between life forms that originated on a different basis?”    Much of this discussion was prompted by the evidence for water found by the Mars Exploration Rovers (see 12/03/2004 headline).  Now, Spirit has found evidence for past water from a layered rock in the Columbia Hills, reports JPL.  For more on the complexity of the hypothetical last universal common ancestor (LUCA), see 02/29/2004 headline.Does water equal life?  Does mud equal a mud-brick pyramid?  Is science the art of building maybes on top of mights?  Does “might” make right?  Can they say the word “genesis” in school?  Does life just “happen”?  Can we say it “happened” when we know very little about the origin of life?  Can students have a chance to hear the controversy about evolution (see next headline), instead of the diet of empty speculation dished out by astrobiologists spending too much time watching old movies and not thinking straight?  Can they hear Jonathan Wells instead of H. G. Wells, and learn some science facts instead of science fiction?(Visited 9 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Organisms Refusing to Evolve Over Millions of Years

first_imgSeveral more cases of “extreme stasis” have turned up, calling into question Darwin’s notion of constant, gradual change over millions of years.Earlier human migration: Science Magazine reports evidence of mammoth bones in Siberia that indicate hunting and butchering by humans, 10,000 years earlier than evolutionists presumed people should have been up those cold climes. New Scientist‘s headline reads, “Humans adapted to Arctic life 10,000 years earlier than thought.” The bones are claimed to be 45,000 years old; that means that humans were essentially the same as us—intelligent, adaptable and capable—for at least 8 times all recorded human history (actually, much longer: they believe upright, thinking hominins existed for 1-2 million years). That phrase “earlier than thought” shows up a lot in evolutionary studies. It means that evolutionists are surprised at cases of early appearance and stasis. This pattern stretches into much longer time periods in the following examples.Tree shrews refused to evolve for 34 million years, Science Magazine says. A new fossil doubles its period of stasis. It has a “living fossil” story to tell:Tree shrews are often held up as being living fossils, presumably very similar to our own earliest primate ancestor. The dearth of actual fossils of these small tropical mammals, however, has meant that much of this conclusion has been speculative. Li and Ni describe a new fossil tree shrew that is exceedingly similar to the extant pen-tailed tree shrew (Ptilocercus lowii), yet twice as old as any previously described sister taxa. The fossil suggests that this tree shrew has gone nearly unchanged since the Oligocene (over 34 million years ago).Squid stasis for a much longer period was reported in Live Science. Belemnites are members of the Cephalopod (head-foot) class that includes octopuses, squid and cuttlefish. Fossils found in Solnhofen, Germany (home of Archaeopteryx and other exceptionally-detailed fossils of the Jurassic Period) show that one species was already highly skilled. “Generally speaking, Acanthoteuthis‘ fins and bullet-shaped body, much like modern squids’, suggest that it would be a good swimmer,” the article says. The Jurassic is claimed to span from 200 to 145 million years ago. Noting that cephalopods date back even farther, “500 million years,” the article points out that squid like this possessed balance-sensing organs (statocysts), muscles, cartilage, a digestive system, and 10 arms. Cephalopods also have exquisite eyes as complex as those of mammals, yet are not related to any tetrapods in the evolutionary scheme. For a type of animal that is abundant today, this squid had an awful long time to evolve into something else, but it didn’t. Its statocysts, for instance, “resembled structures found in pelagic squid” that swim in the same oceans today.Crustacean stasis: A division of crustaceans called branchiopods includes many living species, including water fleas and fairy shrimp. Current Biology published a find with a headline that tells all: “A 365-Million-Year-Old Freshwater Community Reveals Morphological and Ecological Stasis in Branchiopod Crustaceans.” This phylum dates to the Cambrian Explosion. Early fossils of branchiopods have been found in fossil beds as widely dispersed as Canada, Scotland and Sweden. This new find in Belgium tops them all, yet looks strangely familiar:Here we report the discovery of an ephemeral pool branchiopod community from the 365-million-year-old Strud locality of Belgium. It is characterized by new anostracans and spinicaudatans, closely resembling extant species, and the earliest notostracan, Strudops goldenbergi. These branchiopods released resting eggs into the sediment in a manner similar to their modern representatives. We infer that this reproductive strategy was critical to overcoming environmental constraints such as seasonal desiccation imposed by living on land. The pioneer colonization of ephemeral freshwater pools by branchiopods in the Devonian was followed by remarkable ecological and morphological stasis that persists to the present day.Not only do the bodies (morphology) look the same, the whole community (ecology) looks the same. How do evolutionists deal with the fact that this fossil bed looks like it was buried recently? These biologists got creative with their Darwinian imaginations. The creatures evolved, they say, but not in ways that are visible to the human eye—they used encryption!The ecological and morphological stasis may be explained by the mixing of eggs from decades-distant populations, a singularity likely to prevent the fixation of new phenotypic variations. Nonetheless, the apparent morphological stasis does not mean that these clades did not evolve through time, but rather that the changes are cryptic, as revealed by changes in egg size. In addition, variations in physiology and egg hatching phenology have been reported for several species without significant morphological change and seem to be important for the long-term occupation of ephemeral pool biotopes. Fishes are generally absent in ephemeral pools, and increased fish predation in marine and fluvial environments during the Devonian may have triggered the modifications that allowed large branchiopods to colonize these continental environments devoid of predators. Paradoxically, the variable and harsh ephemeral pool appears to have been one of the most stable continental ecosystems over hundreds of millions of years.This admission is amazing. They found an ephemeral pool that should have been subject to variation and harsh environmental change, yet their dating of the fossils forces them to say it must have been “one of the most stable continental ecosystems over hundreds of millions of years.” Were there not meteors, tsunamis, continents subducting, and other dramatic geological changes, including major extinctions, in 365 million years?B as in billions: The winner for stasis is the bacterium. PhysOrg discusses “evidence of cavity-dwelling microbial life from 3 billion years ago,” from a time when there was not supposed to be oxygen or protection from UV radiation. Supposedly, South African greenstone beds allowed microbes to shield themselves by dwelling in cavities in the rock. Notice the word similar in what they say about these microbes:The team conducted multiple tests on the mats and the microbes found hidden under them, including bulk carbon and SEM analysis and Raman micro-spectroscopy and report that the microbes were shaped like rods, growing in train like filaments, similar to many bacteria alive today. They note also that the microbes were quite uniform in shape and that they were able to control their diameter and length as modern microbes do. The fossils are also approximately 500 million years older than any other previous fossil found in a habitat, and thus represent some of the earliest forms of life ever found (the very earliest date back to approximately 3.43 billion years ago.)With their short generation times, bacteria should evolve very rapidly. Wouldn’t anyone get bored living in a rod-shaped cell for billions of years?Wag your head in astonishment at the credulity of the modern evolutionary biologist. When they jumped onto Darwin’s bandwagon in 1859, and got drunk with his Darwine snake oil, their inhibitions over just-so storytelling faded away. They let go of their scientific rigor and all joined in singing, “How dry I am.” What they didn’t know was that Charlie bamboozled them. He sold them the Stuff Happens Law and tricked them into thinking Darwine was a health tonic; “Everything evolves constantly,” he would say, “except when it doesn’t. When something stays the same for billions of years, that’s evolution, too!” He used his own lyrics. He was really singing, “How wry I am.”(Visited 72 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

The service was developed and managed by Turner Classic Movies (TCM) in collaboration with the Criterion Collection and is available online and as an app across a number of streaming platforms.Curzon’s involvement in the project comes after it launched a membership SVOD service called Curzon12 last year. This allows Curzon cinema members to stream 12 ‘essential films’ for free at home each month by entering their Curzon membership number.last_img read more

Abnormal vision in childhood can affect development of brain areas responsible for

first_imgReviewed by James Ives, M.Psych. (Editor)Oct 15 2018A research team has discovered that abnormal vision in childhood can affect the development of higher-level brain areas responsible for things such as attention.The researchers from the University of Waterloo, University of British Columbia, and the University of Auckland uncovered differences in how the brain processes visual information in patients with various types of lazy eye. In doing so, they are the first to demonstrate that the brain can divert attention away from a lazy eye when both eyes are open.”Current treatments for lazy eye primarily target the early stages of visual processing within the brain,” said Ben Thompson, a professor in Waterloo’s School of Optometry and Vision Science.”The results from this study show us that new treatments should also target higher-level processes such as attention.”Related StoriesResearch team to create new technology for tackling concussionNeural pathways explain the relationship between imagination and willingness to helpDon’t Miss the Blood-Brain Barrier Drug Delivery (B3DD) Summit this AugustLazy eye, known as amblyopia, is a loss of vision that originates in the brain, typically when a child develops an eye turn (strabismic type) or a substantial difference in refractive error between the eyes (anisometropic type). The unequal input causes the brain to ignore information from the weaker eye during brain development. Conventionally, eyecare practitioners treated the different types of lazy eye similarly, primarily because the visual impairments experienced appeared to be the same.In this study lead researcher, Amy Chow, and her colleagues asked patients to pay attention to a specific set of dots among a group of distracting dots, all moving on a computer screen. However, the tracked dots were only visible in one eye (the weaker eye) while the distracting dots were visible only to the other eye (the stronger eye).For people with normal vision as well as those with anisometropic amblyopia, showing different images between the two eyes didn’t matter. Both groups were able to overcome the distracting interference and track the dots successfully. Patients with strabismic amblyopia, on the other hand, were unable to direct their attention to the target dots when they were visible to only the weaker eye.”One of the underlying reasons why some people with lazy eye have poor vision comes down to how the brain suppresses an eye,” said Chow, a PhD student at the School of Optometry and Vision Science at Waterloo. “The poorer-seeing eye is open, the retina is healthy and sending information through to the brain, yet that information does not reach conscious awareness as the brain chooses not to use it.”About thirty-five thousand Canadians – one per cent of the population – have strabismic amblyopia. The condition can be corrected in childhood, but treatment efficacy can be highly variable. These findings are a stepping stone in developing better treatments of lazy eye.

Whistleblower charges Walmart misled on ecommerce data in catchup race with Amazon

This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. A whistleblowing former employee alleges Walmart issued misleading e-commerce data in its race to catch up with retail rival Amazon.com, and then fired him in retaliation when he refused to stop complaining about the practice. ©2018 USA Today Distributed by Tribune Content Agency, LLC. Tri Huynh, a former Walmart director of business development, charged in a federal lawsuit filed Thursday that the company used questionable practices to “paint an overly-optimistic picture” of its e-commerce results as it vies with Amazon for the title of world’s largest retailer.Huynh said corporate superiors brushed off his complaints. After he instead sent his allegations to top Walmart executives in January 2017, the company fired him, Huynh alleged.”Walmart sacrificed and betrayed its founder’s key principles of integrity and honesty, pushing those core values aside in its rush to win the e-commerce war at all costs,” Huynh charged in the whistleblower lawsuit filed in San Francisco. “In doing this, it realized it must silence any whistleblower who spoke up against its ‘win at all costs’ approach to e-commerce growth.”Walmart said Huynh’s allegations lack merit.”This litigation is based on allegations by a disgruntled former associate, who was let go as part of an overall restructuring,” spokesman Greg Hitt said in a corporate statement. “We take allegations like this seriously and looked into them when they were brought to our attention. The investigation found nothing to suggest that the company acted improperly. We intend to vigorously defend the company against these claims.”Walmart shares closed down fractionally at $87.51 in Thursday trading.The charges come amid Walmart’s efforts to beef up its e-commerce business, an area in which Amazon historically held a substantial edge. The company has increased e-commerce spending, including roughly $3 billion for its 2016 acquisition of startup Jet.com.Walmart reported a 23% increase in e-commerce growth during the quarter that included the 2017 holiday season. However, the result fell below the previous quarter and also lagged behind the growth reported by Amazon.”We’ve been focusing on building an e-commerce business, that’s still underway, obviously,” said Walmart CEO and President Douglas McMillon during a February conference call with Wall Street analysts in February.Huynh, a former Amazon employee, charged that Walmart’s income from online sales has been misleadingly boosted by questionable practices.The company’s global marketplace platform regularly classified some e-sales by third-party sellers in a category that improperly resulted in “excessive commission fees” for the vendors, the whistleblower lawsuit alleged.Additionally, Walmart classified some returns from e-commerce customers improperly, a problem that skewed the company’s online financial results, the lawsuit charged.Huynh said the previously-glowing job reviews he’d received at Walmart turned to corporate complaints as he continually flagged his e-commerce concerns. Ultimately, he alleged he was fired days after he sent his concerns to Walmart e-commerce CEO Marc Lore and Michael Bender the company’s chief operating officer for e-commerce.Huynh’s lawsuit seeks damages for lost wages and other economic losses, along with emotional distress.

During these feuds, the worms emit one of the loudest sounds in the ocean, according to a new study. The source of the underwater hullabaloo is a nearly transparent segmented worm called the Leocratides kimuraorum, which lives inside sponges 279 to 554 feet (85 to 169 meters) deep off the coast of Japan. [The 12 Weirdest Animal Discoveries] These wigglies are just a tad more than an inch (29 millimeters) long and have lengthy tentacles and a big mouth (literally). These seemingly quiet creatures revealed their true nature under the spotlight in the lab. A group of researchers used an instrument called a hydrophone to record 15 pops that were emitted from three kimuraorums as they were fighting. In a marine feud researchers dub “mouth-fighting,” the worms approached each other headfirst with their mouths open. During such encounters, the worms’ pharynx muscles expand rapidly, creating a cavitation bubble that collapses and produces a loud “pop” while the worms launch into each other. The researchers found that these pops can reach 157 decibels in the water (which is a different measurement than decibels in the air). From right next to the water tank, the pops sounded like humans snapping their fingers, lead author Goto Ryutaro, an assitant professor at Kyoto University told Live Science. “Though they probably sound louder if you hear them in the water.” The worms are as loud as snapping shrimps, which are one of the biggest noisemakers in the ocean, the authors wrote. What’s more, they found that these worms did not make any noise when simply disturbed, they only did so when they were fighting. They “may use mouth-fighting to defend territory or living chambers from other worms,” the authors wrote July 8 in the journal Current Biology. “A loud pop may be a byproduct of the rapid mouth attack, but it may also aid intraspecific communication.” A loud noise could somehow determine the victor of the fight or even reveal the whereabouts of nearby worms, they wrote.

Congress AAP alliance Delhi Congress leaves decision to Rahul Gandhi

Congress still mulling alliance with AAP March 25, 2019 political developmentcenter_img Elections 2019 alliances and coalition Stitching up alliances, a challenge for Congress File photo of Rahul Gandhi, President of Congress party   –  REUTERS Delhi Congress President Sheila Dikshit and other leaders of the unit on Monday discussed the possibility of an alliance with the AAP for the Lok Sabha elections in the city in a meeting with party chief Rahul Gandhi.The opinion remained divided on the issue and everyone in the meeting was unanimous that Gandhi should take a final call on it in the larger interest of the party, said a participant of the meeting.Sources said four former Delhi Congress presidents — Ajay Maken, Subhash Chopra, Tajdar Babar and Arvinder Singh Lovely — favoured an alliance with the Aam Aadmi Party in Delhi.“AICC in-charge of Delhi Congress PC Chacko also handed over signed letters of 12 district Congress presidents, leaders of the party and councillors in three municipal corporation, in favour of the alliance to Gandhi,” they said.“Delhi Congress president Sheila Dikshit and three working presidents Devender Yadav, Rajesh Lilothia, and Haroon Yusuf maintained their stand against the alliance,” sources said.The AAP has been seeking an alliance with the Congress in Delhi but the grand old party has not made its stand clear on the possible tie-up. However, after getting no clear response from the Congress, the AAP declared its last candidate in Delhi for the Lok Sabha polls, with a senior leader saying the announcement was made seeing the Congress’ “irresponsible and indecisive” attitude towards the alliance.Delhi Chief Minister and AAP national convenor Arvind Kejriwal had also said internal surveys have indicated that the AAP is capable of winning all seven seats in Delhi on its own and it does not require an alliance with the Congress in Delhi. However, the Congress and the AAP last Tuesday made fresh efforts with the help of NCP chief Sharad Pawar to forge an alliance in Delhi for the polls.Sources said last week AAP made a fresh bid to forge an alliance with the Congress in Punjab, Haryana and Delhi, with the former demanding five seats in the national capital. However, shortly after the meeting Kejriwal said that the Congress has refused to form an alliance with the AAP in Delhi and the two parties are not in talks with each other.
