Read Full Story Imagine an automobile coating that changes its structure to adapt to a humid environment or a salt-covered road, better protecting the car from corrosion. Or consider a soldier’s uniform that could alter its own camouflage or more effectively protect against poison gas or shrapnel upon contact.A trio of university researchers from Harvard School of Engineering and Applied Sciences (SEAS), the University of Illinois, and the University of Pittsburgh Swanson School of Engineering is proposing to advance 3D printing one step—or rather, one dimension—further. Thanks to an $855,000 grant from the United States Army Research Office, the group proposes to develop 4D materials that can exhibit behavior that changes over time.

The latest speculations about life’s origins always overlook the most essential component: the origin of biological information.Suggestive catch-phrases are no substitute for demonstration. Evolutionary scientists employ stock phrases like “missing link” and “RNA world” and “prebiotic soup” that conceal, rather than illuminate, the actual chemical problems getting from molecules to life. The so-called “building blocks of life,” like a pile of bricks, can do nothing on their own without guidance from information in blueprints and the mechanisms to convert information into structure.Here’s the latest news about origin-of-life studies (OOL for short). Watch how researchers and reporters use language with the power of suggestion and a high perhapsimaybecouldness index to conceal serious difficulties.“It reminds me of the Fairy Godmother in Cinderella, who waves a wand and ‘poof’….”Potential ‘missing link’ in chemistry that led to life on Earth discovered (Science Daily). Anything could be a “potential” missing link if the path is sufficiently convoluted. OOL-er Ramanarayanan Krishnamurthy at The Scripps Research Institute (TSRI) is proposing diamidophosphate (DAP) as a missing link. In his fairy tale, he brazenly commits the poof spoof:Krishnamurthy and his colleagues have shown previously that DAP can efficiently phosphorylate a variety of simple sugars and thus help construct phosphorus-containing carbohydrates that would have been involved in early life forms. Their new work suggests that DAP could have had a much more central role in the origins of life.“It reminds me of the Fairy Godmother in Cinderella, who waves a wand and ‘poof,’ ‘poof,’ ‘poof,’ everything simple is transformed into something more complex and interesting,” Krishnamurthy said.In this “scenario” Krishnamurthy started with the ingredients, but just used DAP to facilitate phosphorylation. Although this over-confident piece mentions the need for nucleic acids to “store genetic information,” it never tells where the information comes from.Experimental evidence overturns accepted theory (Science Daily). Down with the RNA World! That’s basically what two teams are saying in this article, “overturning accepted theory” for a different and equally speculative scenario.Life on Earth originated in an intimate partnership between the nucleic acids (genetic instructions for all organisms) and small proteins called peptides, according to two new papers from biochemists and biologists at the University of North Carolina at Chapel Hill and the University of Auckland. Their “peptide-RNA” hypothesis contradicts the widely-held “RNA-world” hypothesis, which states that life originated from nucleic acids and only later evolved to include proteins.What do these two “worlds” have in common? They both lack a theory for the origin of biological information. The papers focus on how nucleic acids and peptides need to work together, but overlook the weightier problem of installing coded information into the molecules. Here is a classic quote employing several of the OOL catch-phrases. Notice how the boastful assertions in the first paragraph are followed up by complete ignorance in the second paragraph concerning the key issue of programming:Before there was life on Earth, there were simple chemicals. Somehow, they produced both amino acids and nucleotides that eventually became the proteins and nucleic acids necessary to create single cells. And the single cells became plants and animals. Research this century has revealed how the primordial chemical soup created the building blocks of life. There is also widespread scientific consensus on the historical path by which cells evolved into plants and animals.But it’s still a mystery how the amino acid building blocks were first assembled according to coded nucleic acid templates into the proteins that formed the machinery of all cells.They propose a tight “relationship” between RNA and peptides mediated through the amino-acyl tRNA synthetases (aaRS) or their assumed “ancestors”. How these ancestors emerged is not clear, but the OOL-ers speculate that a code emerged through a “strange loop” of self-reinforcing interactions. Maybe it’s something like the letters q and u becoming matched in words like quick and quiet, such that all subsequent information led to the works of Shakespeare. If you don’t believe that, then you sure can’t believe the RNA-World story, because even these researchers know that one doesn’t make sense:“Such a rise from RNA to cell-based life would have required an out-of-the-blue appearance of an aaRS-like protein that worked even better than its adapted RNA counterpart,” Carter said. “That extremely unlikely event would have needed to happen not just once but multiple times — once for every amino acid in the existing gene-protein code. It just doesn’t make sense.“While we’re
A study conducted by the Department of Human Development and Family Studies at Michigan State University found thatMany service members are returning home from combat, but a large number of these individuals have come home at a price. These service members may have experienced significant changes in abilities resulting from loss of limbs; vision or hearing; severe burns; spinal cord injury; traumatic brain injury or posttraumatic stress disorder. Whatever the injury, adapting can be difficult during the reintegration process for wounded service members and their families.Often times these injuries can unavoidably affect children living in the home and may have an impact on their well-being. By addressing the potential impact of parental injury on children and identifying ways of dealing with the issues, military families can maintain the long-term health and well-being of their children.Factors effecting how a child interprets an injurySeveral factors must be taken into account with how a child interprets an injury.Obviousness of the Injury–Depending on the severity of the injury and whether it is an invisible or physical injury will determine the wounded warrior’s involvement in daily parental routines. This can sometimes be confusing to children and they may feel rejected, confused, and angry or display a whole range of emotions related to the change.Changes in the home–Caring for a wounded service member ultimately results in changes within the home. The demands related to caring for the injured may overshadow the parent’s ability to meet the needs of a child, resulting in a negative impact on the child’s emotional, social, and physical development.Age of the child–Age of children can determine how they perceive changes in the service member and how they react to these changes. For example, an older child might perceive changes in the service member from pre-deployment to post-deployment as drastic; this perception may lead to a complete change in the relationship between the two.Minimizing the effects of an injury on a childIt is important to keep in mind that there are actions that parents and caregivers can take to help minimize the effects of an injury on a child.Open, age-appropriate communication–Communication provides reassurance to children about the future.Family routines and rituals–Deployments and reintegration into civilian life can interrupt normal family routines. When a returning service member comes home, establishing regular routines may improve the household environment for children.Use of a support network–A support network can include other caregivers, family members and friends that can increase the number of positive, supportive attachment relationships in the child’s life.Consult a Professional–With an array of resources and services tailored to meet the needs of service members and their families, it may be helpful to seek professional help (e.g. psychotherapist, child therapist, etc.) in helping children negotiate the difficulties related to deployment injury.Whatever your service member’s condition may be, it is important to fully understand not only how it will affect your life but the life of your children.Check out Michigan State University’s new article on Effects of Visible and Invisible Parent Combat Injuries on Children to learn more on how you can better understand the effects of your service members injuries on children.
Spanish tennis star Rafael Nadal has said Swiss great Roger Federer pulled out of the Paris Masters so he could be in top form for the ATP Finals, which will be held in London.”After winning Shanghai and winning Basel, he believes (missing Paris) will be better for his body and for his preparation for London,” Nadal said in a press conference in Paris on Monday, Efe news reported.Federer, winner of a record 19 Grand Slam titles, announced his withdrawal from Paris, the last Masters event of the year, after clinching his 8th Swiss Indoors title in his hometown of Basel on Sunday.The 36-year-old Federer has been planning his 2017 schedule more carefully after missing almost the whole second half of the 2016 season due to an injury.Federer skipped the entire clay-court season in 2017, but he has won seven titles, including the Australian Open and Wimbledon.Federer’s decision paved the way for Nadal to end the year as world number 1 for first time since 2013 with just one win in the tournament.”Let’s see. I need to win a match. But I am here to try my best, as in every tournament,” Nadal said of a tournament he has never won.”Of course, if that happens, it will be something important for me. But season is not over and this is not the moment to think much about that. I will just try to think about trying to have the right preparation for the tournament and then try to be ready for the first match,” the 31-year-old Nadal said.advertisementNadal regained top form in 2017 after an injury-plagued couple of seasons, winning six titles, including his 10th Roland Garros trophy and third US Open crown.The 16-time Grand Slam champion said he was about the situation in Catalonia, where the regional parliament declared independence from Spain, prompting the Spanish government to impose direct rule over the region.Nadal, who criticized the independence bid, said these were tough times for both Spaniards and Catalans, but that he had faith in the ability of Spanish democracy to overcome the situation.
Real Madrid fullback Carvajal: We should’ve finished off Villarrealby Carlos Volcano10 months agoSend to a friendShare the loveReal Madrid fullback Dani Carvajal admits they blew two points for their draw with Villarreal.Real kicked off 2019 with a 2-2 draw against the Yellow Submarine.Carvajal lamented, “We had some real chances to finish the game and make it 1-3, but in the end, we drew and dropped two points. We needed those three points to close the gaps on the leader. Now we need to keep working hard and rack up some points. This is not an easy place to come play. We’re disappointed because we were ahead for practically the whole match and not winning really stings.””We knew that they would have to push forward and leave the defence open. Before finishing with a draw, we had two massive chances to kill it off, we did not finish and they nicked a goal at the end.” About the authorCarlos VolcanoShare the loveHave your say
zoom Malaysian authorities have sentenced eleven Indonesian pirates each to sixteen years in prison following their failed hijacking attempt, the Jakarta Post cited undisclosed officials.The men attempted to hijack a Thai-flagged oil tanker while it was sailing off the coast of Malaysia in early September.The group of 13 perpetrators managed to board the tanker MGT 1 and force the crew to transfer one million litres of diesel oil (out of 2.2 million litres contained in the tanker) to a mother ship.Ten of the pirates were captured and sentenced to jail, while the search was launched for the remaining three. A Malaysian court sent another individual, who led the operation from land, to prison.At the time, the vessel was underway from Rayong port, Thailand to the Andaman Sea.Asia’s piracy watchdog ReCAAP earlier said that the crew managed to activate the SSAS alarm and the tanker was soon rescued by the Malaysia Maritime Enforcement Agency (MMEA), which dispatched two ships and a helicopter to the location.World Maritime News Staff
LEAVE A REPLY Cancel replyLog in to leave a comment Last year, GLAAD noted the deaths of several queer female characters and called on broadcast networks to ensure that lesbian and bisexual women on TV fared better the following year. But this year’s report cites at least 12 lesbian and bisexual female characters who have been killed off broadcast shows since January, and says more than 25 queer female characters have been killed across all platforms this year.The report directly references the “Bury Your Gays” trope, a term activists used this year while protesting the deaths of lesbian and bisexual characters, who often see violent deaths or meet tragic ends following happy moments.Fans were particularly outraged after CW’s dystopian teen drama The 100 killed off a beloved character in March. In response, they formed LGBT Fans Deserve Better, an initiative that has continued to track the deaths of lesbian and bisexual female characters, and has raised more than $150,000 for The Trevor Project, which provides a 24-hour, toll-free crisis hotline and other services for LGBTQ youth.In an intro to the report, GLAAD president and CEO Sarah Kate Ellis wrote that “the decision to kill these characters in droves sends a toxic message about the worth of queer female stories,” adding that LGBTQ characters should have “the same opportunities for romance, nuanced motivation, developed back story and the same odds of death” as their straight, cisgender counterparts.And while overall bisexual representation increased on broadcast and streaming networks, GLAAD says it continues to see harmful tropes played out around characters who identify as bisexual, often portraying them as manipulative or untrustworthy. The report notes that these traits factored into unsettling character deaths on shows including ABC’s The Catch and Fox’s Empire.Bisexual women outnumber bisexual men across platforms; out of 21 characters identified as bisexual, only five are men. But GLAAD praised CW’s musical comedy Crazy Ex-Girlfriend and Freeform’s Shadowhunters for depicting bisexual male characters whose stories dispel negative stereotypes.GLAAD says the number of transgender characters has more than doubled since last year. Out of 16 transgender characters, three are on broadcast networks, none of which had shows with transgender characters last year. That means transgender characters will appear across all platforms. The report cites Amazon’s Transparent as the most LGBTQ-inclusive series. GLAAD notes that the dramedy, which stars Jeffrey Tambor as a 70-year-old transgender woman, features two other transgender characters (both played by transgender actors) and three other characters identified as LGBT.By Bethonie Butler – The Washington Post Advertisement Advertisement Twitter The group began tracking more comprehensive diversity data in 2005, and this year’s report also identifies record-high percentages of black characters and characters with disabilities. But the group offers a mixed assessment of overall LGBTQ representation for the 2016-2017 TV season.GLAAD reports that lesbian representation “decreased dramatically” from 33 per cent last year to 17 per cent this year. The exception is on streaming networks, where lesbians account for the majority of LGBTQ character representation. GLAAD cites record-high LGBTQ representation in its annual report on television diversity, but the media advocacy group says that television “failed queer women” this year, killing off a staggering number of lesbian and bisexual female characters.The annual “Where We Are on TV” report has analyzed the presence of lesbian, gay, bisexual, transgender and queer characters on prime-time broadcast and cable television for more than two decades. Last year, the group began tracking characters in first-run scripted series released by streaming networks Netflix, Hulu and Amazon. This year’s report, released Thursday, cites the highest-ever percentage of LGBTQ characters on broadcast television.Out of the five major broadcast networks, ABC has the highest percentage (7.3 per cent) of LGBTQ characters who are series regulars. Fox follows at 6.4 per cent, larger than the overall broadcast percentage of 4.8 per cent. Login/Register With: Facebook Advertisement
