TCU beats TCU, 13-7, in spring football game

TCU baseball finds their biggest fan just by saying hello TCU rowing program strengthens after facing COVID-19 setbacks ReddIt Grant McGalliardhttps://www.tcu360.com/author/grant-mcgalliard/ Grant McGalliardhttps://www.tcu360.com/author/grant-mcgalliard/ Facebook TCU students receive evacuation text by mistake printFreshmen Horned Frogs shined, the quarterback controversy went unsolved, and Gary Patterson spent over half of the game mingling with fans in the crowd at the TCU spring football game Friday night at Amon G. Carter Stadium.It was a relaxed atmosphere at the event, as a DJ pumped music through speakers near the field during the game and families and students mixed together in the stands. A solid crowd turned out to watch the game; most of the lower bowl on the side that normally holds the student section was filled.The offense, wearing purple and consisting of four squads helmed by each of the quarterbacks on the roster, managed just 13 points against the defense, who wore white and returned an errant pass for a touchdown of their own.Still, Patterson said postgame that he’s not putting too much stock into anything he saw tonight — not that he saw much of the game at all, as he was taking pictures with the Horned Frog faithful in the stands.“I’ll get a chance to watch tomorrow and see what goes on,” Patterson said. “This is what it’s all about, to give back to the fans.”“I didn’t watch that close. I spent probably 40 minutes on both sidelines telling everybody thank you.”Kenny Hill and Foster Sawyer worked with the first and second-strings, respectively. Hill made several accurate throws that were dropped by his receivers, which Patterson noted was a problem.“As a whole team, we’ve gotta catch the vertical ball better,” Patterson said. “It’s what we gotta do between now and August.”Sawyer had some strong completions down the field, but was intercepted for a pick-six by sophomore defensive end Tipa Galeia, who made an acrobatic catch that drew cheers from the crowd.Patterson said nothing on the quarterback front changed as a result of the night’s performances.“Tonight, Kenny started because it was his turn to start with the ones,” Patterson said. “But we’ll go into fall camp with two guys working to be the starting quarterback.”Grayson Muehlstein, who started with the third-string squad, provided the game’s lone touchdown on a pass to Taj Williams, a highly-touted junior college transfer. Jonathan Song added two mid-range field goals to complete the scoring for the offense.The best performances of the night arguably both came from freshmen. Redshirted newcomer Jeff Gladney played lockdown defense on wide receiver Deante Gray for much of the night, jamming his man at the line of scrimmage and causing several balls to fly over their intended targets.“Both him and Tony [James] did some good things out here,” Patterson said, “but they’ve got a long way to go to play on a consistent basis against the people we have to play against.”Running back Sewo Olonilua also stood out among the crowd. After fumbling on a carry, he bounced back and took his next touch 33 yards to set up Muehlstein’s touchdown pass.“He was good against the [third string],” Patterson said, “but against the [first and second string] he was just okay.”This game was Horned Frog fans’ last chance to see TCU in uniform before the season begins in September against South Dakota State.

Hulkamania running wild again in WWE return

first_imgIn this April 3, 2005, file photo, Hulk Hogan fires up the crowd between matches during WrestleMania 21 in Los Angeles. (AP Photo/Chris Carlson, File)Hulkamania is running wild again in the WWE.Hulk Hogan, perhaps the biggest star in the company’s 50-year history, is set to bring the red-and-yellow back to the sports entertainment behemoth and will host the April 6 WrestleMania in New Orleans.Hogan returns to the WWE after a six-year absence and will be on Monday’s “Raw” on the USA Network.  Hogan will also bring the muscle for the WWE’s launch of its own network: He will appear on “WWE Raw Backstage Pass,” airing live on WWE Network at 11:05 p.m. on Monday night.“I definitely want to stay here in the WWE,” Hogan told The Associated Press on Friday. “I just can’t see myself ever being anywhere else. This is home. It always has been home. In the twilight of my career, what a great way to be part of the final hurrah for Hulk Hogan and all the Hulkamaniacs.”The 60-year-old Hogan’s return is perfectly timed for both the 30th WrestleMania and the new network, which debuts Monday as a streaming service for $9.99 per month with a six-month commitment and will include all 12 pay-per-view events.Hogan last appeared on WWE’s flagship show “Raw” in December 2007.Hogan was the main draw for the first WrestleMania in 1985 and was a fixture for years in WWE’s signature event, facing everyone from Andre The Giant and Randy Savage to The Rock and, yes, company chairman Vince McMahon. He’s in shape and could be ready to mix it up, if needed, at the Superdome.But no WrestleMania match is scheduled.“Right now, it’s not in the plans,” Hogan said. “But like they say in the WWE, never say never.”Hogan, starting his fourth stint with the WWE, said he would participate in WWE Network programming and make community and media relations appearances for the company.Hulkamania was born in 1984 when he defeated The Iron Sheik to become WWE champion at Madison Square Garden. He won six WWE championships and was inducted into the WWE Hall of Fame in 2005 by Sylvester Stallone.“It’s time for him to come home,” said Paul “Triple H” Levesque, a wrestler and top WWE executive. Hogan and Triple H met at a charity event late last year, which started to lay the groundwork for The Hulkster’s return.Hogan is the latest estranged star to return to the company in the last two years, joining Bruno Sammartino and The Ultimate Warrior.In his absence, WWE certainly hasn’t forgotten about Hogan, putting him on the cover of its recent DVD release “The Best of WWE at Madison Square Garden.” He’s also a playable character in six classic WrestleMania matches in 2K Sports’ “WWE2K14” video game that came out late last year.“I don’t think there’s ever been a doubt that Hulk Hogan was, in some way, a WWE commodity,” Levesque said.Hogan has also wrestled for other promotions including the now-defunct World Championship Wrestling and spent the last four years with TNA Wrestling. Like his bad guy Hollywood Hogan personna would have said, he hoped this relationship with WWE was “4 Life.”“It looks like this was always the direction I was going to go in,” Hogan said. “It’s like I drifted apart from home base for a while. But this time, everything seems to be a perfect fit.”last_img read more

Seniors Adjust to Life in Lockdown

first_imgAs with most senior residences, Chelsea Senior Living communities closely follow New Jersey Department of Health guidelines. All employees have the personal protective equipment they need, including masks, gloves, face shields and hand sanitizer, and are screened before each shift.  To keep residents and their families in touch with one another Brighton Gardens uses iPads and schedules Facetime and Skype calls, said Rathgeber.  She chats on the phone with family and friends, and keeps busy reading, most recently Ken Follet and Robert Parker. “I have a dear friend with a lot of books,” she said. “I’m hoping to get another batch from her soon.” The hardest part of quarantine for many of the seniors, Rathgeber said, is understanding why they can’t have visitors.  With the coronavirus touching every aspect of our society, all everyone is affected. Officials, celebrities and loved ones tell us to “Stay home. Stop the spread. Save lives.”  “Communication with families is done through text, email, telephone and video venues. Our residents no longer take their meals in a communal dining room,” he said. “Their meals are delivered to their apartments.”  Some of these seniors – many of them octogenarians or older and many with pre-existing medical conditions – are struggling to accept the changes to their lives. Rose Tamburro has lived through World War II and outlived two husbands and a daughter, but she never thought she’d find herself masked and quarantined in her Lincroft apartment. It’s an unprecedented time but Plant, a widow, and her generation have weathered more: World War II, the Korean and Vietnam wars and 9/11. Plant remembers the Cuban Missile Crisis in 1962 when her children were young. “I was terrified,” Plant recalled. “My husband was coming home early from work. I packed the whole car – baby formulas and all. I was a wreck,” she said of her plans to flee and take cover. “We were going to drive to Pennsylvania.” Now they must rely on family, friends or volunteer groups to shop for their food. Known as the Greatest Generation, many are living alone, suddenly cut off from their activities, houses of worship, even the supermarket. Some who’ve embraced technology may be navigating how to get the news online and what to do when their grandchildren want to talk to them on something called Zoom. Rose Tamburro of Lincroft doesn’t venture out of her apartment without donning her mask. Photo by Judy O’Gorman Alvarez But she spends her time reading the newspaper, chatting with family on the phone, watching TV, cleaning her apartment and cooking. “I love to cook and I love to dance. And I do them both every day in my apartment,” she said. “I cook lamb shank, pasta fagioli, whatever.” In pre-COVID-19 days, the Middletown Senior Center would be organizing bus trips, bingo games and crafts. But nowadays, staff is checking in with seniors to see how they’re faring. Seniors living alone have tried to make the best of it though. Davis said, “It does take a village. And this hardship exemplifies the community spirit and it’s wonderfulto see.” When Barbara Plant’s grandchildren visit, they keep their distance to avoid any possible transmission of the coronavirus. Photo courtesy Pat Nelson So Plant doesn’t spend time ruminating about what she’s missing now. Sure, she’d prefer to be going to breakfast with friends, spending time with family and doing everyday activities. “But so much of that stuff is not that important,” she said. “Some seniors are very stressed,” said Alison Block, a psychologist in Oceanport. “They’re not familiar with technology, they worry they may be ‘hacked,’ and they may be having trouble ordering food online.” At Brighton Gardens in Middletown, like most long-term care and senior living community facilities, residents’ health is closely monitored. Outside visitors and group activities have been suspended and residents stay in their rooms. She points out that a person who “normally would be playing mah-jongg or bridge” has been thrust into a world without those activities. In her practice, specializing in anxiety disorders, Block said, “I’m seeing people cut off from their normal support system.” “We have amazing life enrichment managers,” said Lori Rathgeber, director of sales. “Someone goes into every single apartment, reads to them, plays a game, so that they are getting stimulation every day.” Plant said at Shadow Lake Village in Middletown, an active adult community where she lives, some residents do informal exercises in the parking lot and many of her neighbors play mah-jongg online. “We’re turning a disadvantage into something that’s new and unique.” “And then that got settled,” she said. “And it was over.” “Oh, this is serious,” she said of COVID-19. She only goes for short walks outside her building. “And I always wear my mask.” Her daughter and daughter-in-law bring groceries and hot meals so she doesn’t have to venture to the supermarket. When her grandchildren visit they stand outside the glass door. “We personally contact each member to make sure they have resources and they’re in touch with their family members,” said Kourtney Davis, Middletown Senior Center supervisor.  “If the weather is good, I’ll walk with a girlfriend – but she’s 6 feet away from me,” she said. Staff can advise seniors of stores that may have curbside pickup or contactless checkouts and, if needed, steer them to programs for monetary help such as Lunch Break or Meals on Wheels. Some seniors are frail or convalescing and unable to get out of their homes in nonpandemic times. “We’re here to assist all members,” Davis said. “It’s so important right now for families to be in touch – even if they’re out of state,” said Davis. “That’s where the breakdown can happen. We follow through to make sure everybody is talking.” Some residents have embraced the technology and for some the reactions have been endearing. “We get a lot of ‘Where are you? I can see you, but I can’t touch you.’ ”  Plant admits it’s a trying time and she’s had disappointments; her 85th birthday celebration was scheduled for the Molly Pitcher Inn. “We had to cancel,” she said. “But that’s neither here nor there.”  She misses attending the Zumba classes the building used to run and daily Mass at St. Leo the Great church across the street. “I don’t know when we’ll be able to go back,” she said.  Keeping seniors safe is on the minds of the Monmouth County Freeholders who have launched initiatives to help them, including expanding SCAT service, early morning transportation for seniors to take advantage of designated shopping hours offered by many grocery stores and other essential retail locations. “People are talking about dying,” Block said of seniors and the middle-aged. “I’ve had people who have said to me, ‘I’m not afraid to die, but I’m afraid to die alone.’ ”  And she has discovered she has a penchant for online shopping, although among the purchases are some she plans to return. “I have so much that has to go back to Talbot’s when this is all over.” Easter came and went with barely a celebration but Tamburro’s grandchildren and dog came to visit – social distance-style. “They came to the window with plants and homemade cookies,” said Tamburro, who lives on the first floor. They sang “Happy Easter” and left the gifts on the chair outside her window so she could retrieve them later. “We have had a strict no-visitation policy in effect since March 12th,” said Tom Kranz, director of communications, in an email.  But according to the Centers for Disease Control and Prevention, people 65 years and older are considered at high risk for severe illness from COVID-19, the disease caused by the virus.  She urges everyone to ask themselves, “What can we all do to help our seniors?” Sometimes that means chatting with seniors about their concerns, especially about fears and isolation. “There is a loneliness factor, of course,” said Davis, “when you’re afraid to leave your house. But I’ve heard great things too, like it’s an opportunity to finally clean out that drawer, tackle projects.” Rose Tamburro has heeded the warning to stay home and out of supermarkets – even though she lives in a senior living apartment house adjacent to the Lincroft Acme. Instead, her daughter comes to drop off groceries.  “The health and safety of our residents and employees has always been and remains our number one priority,” said Kranz. She allows herself a walk to a small nearby store and recently brought a bagel back for a neighbor. “When she opened the door I threw her the bag – keeping 6 feet back – and she threw me a kiss,” Tamburro laughed. “It’s what we have to do.” Perhaps the most important role of the senior center is keeping the lines of communication open, especially between the senior and their family. Each member has supplied the center with an emergency contact to be called if their loved one is possibly at risk.  The article originally appeared in the April 30 – May 6, 2020 print edition of The Two River Times. Some favorite pastimes include residents lining up in their doorways and playing Hall Bingo. “We yell the numbers down the hall,” said Rathgeber. “Or we go down the hall and let them sing karaoke. That’s a lot of fun. You know, you’ve got to get creative.” Barbara Plant celebrated her Easter this year 6 feet away from her loved ones. And even though social distancing can be inconvenient, she doesn’t feel lonely. By Judy O’Gorman Alvarez “Just put me with a book and I’ll be OK.”last_img read more

Is it crime fighting, or a reaction to the USA advisory?

first_imgDear Editor,First, it was the killing of three bandits on the Corentyne, then there was a follow-up with three more killings in Norton Street, Lodge, yet crime continues unabated.Since last Thursday night’s shooting, there have been several other armed robberies, many of which were conducted in broad daylight, so what have we here in Guyana? The point is we are having a lot of piecemeal, double talking, political posturing, on crime with the real crime situation certainly getting out of control. So, let us take a candid look at crime in Guyana.First, it was the Director General, Harmon, speaking for the Government, stating in one voice that Guyana is a beautiful place, one where crime is down and persons should want to visit. Then in the same tone, he confirmed that crime is hurting the economy and foreign investment would shy away from this country.Then, the Police Commissioner came on board shortly after, stating that crime is down, quoting statistical figures from who knows where to support his argument.I guess he was referring to the recent killings of criminals by the Force, hailing this as a success. Be that as it may, crime continues to be a bugbear and nothing seems to stop it.The point I am making here is that the State, speaking through its representatives, the Director General and Commissioner is telling you one thing when the actual reality of the situation is totally different. Crime is a problem, a real big problem and if a comprehensive plan is not put in place things will – as they already have – become really ugly for locals and foreigners alike.The recent killings and the strident statements by the Government have nothing to do with crime fighting, rather, it is a stop-gap reactionary move by the State as a result of the United States Advisory on Guyana. This PNC-led coalition is hard-pressed to stem the harsh criticism levelled against it by the US Government that they were forced to take those drastic measures, otherwise, it was business as usual where crime is concerned.I told myself that I would not bring politics into my discussion on crime but the situation warrants me revealing the facts as it presents itself. This Government has to face the fact that they were and still is too cosy with criminals while in opposition as well as in Government, and as such they have only themselves to blame. One just has to look into the not so distant past and see their political manoeuvres and you would get the picture. This Government appears to only be concerned when the situation becomes sour and dire as the USA Government has indicated.The Americans have been in and out of Guyana since the oil discovery and the superpower is ensuring that its citizens get the maximum-security doing business here. Hence, they have told the Guyana Government that they are not prepared to accept this armed robbery nonsense as normal behaviour. In this regard, we are now faced with these brutal put-downs.But like I said, a piecemeal haphazard approach will get us nowhere, we have to get down to a long term concrete approach on crime to get this scourge under control. That long-term approach has been done in the last Administration and is on some shelf gathering dust. We must take a good look again at our crime plan and work that plan, it is the only way to bring crime down to a minuscule level.Respectfullysubmitted,Neil Adamslast_img read more

Reach Out and Touch Some Robot

first_imgThe news media were excited to report an advance in materials science last week that could pave the way for touchy-feely robots (see BBC News, News @ Nature, LiveScience and National Geographic News, for instance).  Two scientists produced a thin film with touch resolution comparable to that of a human finger, an order of magnitude better than previous attempts.  The work was published in Science.1     While this is indisputably a remarkable achievement, few of the popular articles drew detailed comparisons and contrasts with the capabilities of human skin.  Richard Crowder, in the same issue of Science,2 started his analysis of the paper with a touch of realism: Today’s state-of-the-art dexterous robotic hands cannot achieve tasks that most 6-year-old children can do without thinking, such as tie a shoelace or build a house of cards.  The improvement of the manipulative capabilities of robotic hands requires advances in a wide range of technologies, including mechanics, actuators, sensors, and artificial intelligence.  Many robots—such as NASA’s Robonaunt—have the dexterity required to perform some of the tasks that we take for granted, but replication of the full manipulative capabilities of the human hand is still years away. Calling the development of tactile sensors “one of the most difficult problems in robotics,” went on to describe how difficult it is to measure slippage while gripping an object.  Though he had praise for the touch-sensitive film invented by Maheshwari and Saraf, he continued to underscore the problems facing robot designers emulating a human hand. To appreciate the advantages of having a single sensor for both slip and texture, it is worth considering how it can be integrated into robotic hands that need to restrain and manipulate a wide range of objects under a wide range of conditions.  To achieve a satisfactory grasp, optimal force control is required.  Any movement of a robotic hand may result in the grasped object slipping and possibly being dropped; hence, the sensors on the hand have to register any slippage and adjust the applied forces to bring the object back to rest…. In short, he wrote, “The problem of defining the required grasp force is crucial and can be posed as an optimization problem.”  The new tactile sensory material is thus only part of a multi-faceted problem that will require mastery of many disciplines.  “The next stage in the development of this sensor is to look at its robustness and performance characteristics over time,” Crowder ended.  “Once these issues are resolved, the sensor can be integrated into a dexterous hand, hopefully leading to an improvement in dexterity.”  Fortunately, robotics designers will have their human sense of touch to aid them in this endeavor. 1Maheshwari and Saraf, “High-Resolution Thin-Film Device to Sense Texture by Touch,” Science, 9 June 2006: Vol. 312. no. 5779, pp. 1501 – 1504, DOI: 10.1126/science.1126216. 2Richard Crowder, “Toward Robots That Can Sense Texture by Touch,” Science, 9 June 2006: Vol. 312. no. 5779, pp. 1478 – 1479, DOI: 10.1126/science.1129110. Would you want a robotic hand encircling your neck, with the inventor’s assurance it will only apply the right force to give you a gentle massage?  What if the software, it turns out, needs a patch?     The researchers can be rightly satisfied of their achievement, but use this story as an occasion to consider the wonder of human touch.  Articles like this one on Apologetics Press remind us of the exquisite engineering behind this sense that brings such pleasure and awareness to life.  More than a mere force-sensitive material, human skin is integrated with a powerful processing and feedback apparatus (the central nervous system) with force actuators (muscles) and automatic temperature controls.  In addition, skin is self-repairing, nourished by a circulating network of nutrients, armed with defenses, and able to breathe without leaking.     Inventors can make telescopes stronger than eyes, and machines stronger than muscles, and sensors more precise than nerves.  But let no man boast till he can optimize all capabilities of a human being in a 150-lb package (more or less) and make it all reproduce itself through a cell the size of a pinhead.  Even then, the inventor will not have breathed into his creation the breath of life to make it a living soul.  He will only have underscored the degree of intelligent design it takes to design and optimize integrated, multifunctional systems.     We hope robotics science will continue to advance – not only toward the improvement of our lives, but toward illustrating the principle that integrated, optimized systems do not arise from unguided processes.(Visited 8 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Small Molecules Play Key Roles in Cells

first_imgMolecular biologists are finding a universe of functional small proteins and RNAs that were considered junk or not even known to exist.We often hear that 98% of the human genome is “noncoding” for proteins. This may be a very misleading statistic. Actually, most of the genome is transcribed into RNAs, whether or not those result in the large proteins we know about. Hidden in those transcripts are small molecules known as micro-RNAs, and some longer ones known as “long non-coding RNAs” (lncRNAs) that are increasingly seen as vital in gene regulation. And now, scientists are beginning to uncover transcripts that are translated into protein fragments. Too small to be called proteins, these polypeptides also play vital roles in cell health. The genes that program these small molecules, once dismissed as “junk DNA,” are revealing more sophistication in the genome than previously thought.Research reveals the importance of long non-coding RNA regulating cellular processes (Beth Israel Deaconess Medical Center). This article expressly dismisses the “junk” label for lncRNAs. They found something when they went looking through the genetic junkpile:Long non-coding RNAs appear to be transcribed from our DNA in a similar manner to coding messenger RNAs but are not translated into proteins. While lncRNA molecules do not produce correspondingly lengthy proteins, researchers have wondered whether some of these molecules may contain segments of sequences that can code for very short proteins, or polypeptides.“Whether such small, hidden polypeptides are actually functional, or represent ‘translational noise’ within the cell is still relatively unclear,” said senior author Pier Paolo Pandolfi, MD, PhD, Director of the Cancer Center and Cancer Research Institute at BIDMC. “Our team set about trying to understand to what extent lncRNA molecules might actually encode functional polypeptides, and how important such peptides might be.”The scientists discovered an important role for a 90-base long lncRNA transcript that produces a polypeptide known as SPAR (Small regulatory Polypeptide of Amino acid Response). This small protein, they found, plays “an important role in modulating the activity of the mTORC1 protein complex, which is a critical sensor of nutrient availability within cells.” The mTORC1 protein is a key target for understanding cancer’s unregulated growth. Since this lncRNA is highly expressed in a number of cell types, including muscle, they determined that it plays an important role in muscle repair after injury. It may also fine-tune the mTORC1 complex for different tissue types. Finding roles for small proteins will probably lead to more discoveries, ratcheting down that “98% non-coding” statistic:The results suggest that lncRNAs may have diverse roles and functions. Although they may not code for large proteins, lncRNAs may produce small polypeptides that can fine tune the activity of critical cellular components. The findings also expand the repertoire of peptide-coding genes in the human genome that should be studied and annotated.Small but mighty: Tiny proteins with big roles in biology (Phys.org): This article adds to the growing realization that small polypeptides or “microproteins” exist throughout the cell that have been ignored before now.We all know how hard it is to find something small like a dropped contact lens that blends into the background. It’s similarly tough for biologists to find tiny proteins against the complex background of the cell. But, increasingly, scientists are learning that such microproteins, which are overlooked by traditional detection methods, also have important biological roles to play.Using a new microprotein detection strategy, Salk scientists discovered a human microprotein involved in one of the cells’ key housekeeping tasks: clearing out genetic material that’s no longer needed. The new molecule could provide a better understanding of how the levels of genes, including disease genes, are controlled in the cell.One of the Salk researchers says that this points out “blind spots” in our knowledge of the cell. There are things hidden in plain sight. “You can sequence the whole human genome and never know a protein, like this one, was there because it’s too short and falls below the usual length requirement for gene assignment algorithms.” We mentioned the “NoBody” small protein in the 12/12/16 entry.Small RNAs interact with newly synthesized transcripts to silence chromatin (Phys.org): Researchers in Germany investigated a “fundamental question” that puzzled them for a decade: what role do small RNA transcripts play in regulating the formation of chromatin? It’s becoming clear that some RNAs work on other RNAs instead of DNA. Specifically, small interfering RNAs (siRNA) can interact with nascent RNA transcripts to induce heterochromatin formation. Chromatin is a protein complex around which DNA is wrapped, affecting the availability of genes for transcription. In addition, chromatin contains histone “tags” that regulate how genes are expressed. This article sheds light on how small RNA and protein pieces interact in this complex regulatory dance.How repair protein finds DNA damage: Like a first responder, protein quickly scans for damage and slows down to flag DNA repair machinery (Science Daily): This article reveals proteins that do triage before the paramedics arrive, so to speak.“Rad4 is like the cop who is the first responder at an accident,” said senior author Bennett Van Houten, Ph.D., Richard M. Cyert Professor of Molecular Oncology, Pitt School of Medicine, and co-leader of UPCI’s Molecular and Cellular Cancer Biology Program. “The cop can move quickly to recognize where the incident is, and regulate traffic while directing the paramedics arriving in an ambulance.”In other words, RAD4 doesn’t do the surgery, but speeds along the DNA with the ability to recognize where the surgeon needs to work. It’s hard for the researchers to avoid anthropomorphic terms for these smart molecules:When structural damage is confirmed, Rad4-Rad23 stays near the scene and flags down the ‘paramedics,’ comprising the rest of the DNA repair machinery, to fix the damage. This mechanism, which Dr. Van Houten calls ‘recognition-at-a-distance,’ allows Rad4 to be near the error without impeding the rest of the DNA repair crew.The old “junk DNA” myth continues eroding. Molecular biologists are seeing, more and more, that even the major league players (proteins and genes) can’t play the game without the bat boys, base sweepers, groundskeepers and other assistants who keep the field in good condition.Did the big proteins evolve from the microproteins? Only in Darwinian dreams. What use is a base sweeper without a pitcher, batter, catcher, umpire, and manager? A robotic base sweeper can sweep home plate for a billion years and nothing more will happen. What we see here is a finely-coordinated system of large and small players working together on a common goal: running a smooth operation that allows the batter to run the bases.Intelligent design predicted this. Unguided evolution predicted junk DNA and vestigial organs. If the ability to make predictions matters in science, which position should gain the ascendancy now?(Visited 53 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more
