Stem cell source is found

first_imgA team of American researchers has found a way to easily identify stem cells in the testicles of adult mice that can be coaxed to turn into brain cells, muscle cells, heart cells, blood cells and even blood vessels. One day, they say, male patients may be able to turn to their own testicles as a source of stem cells to repair hearts or kidneys or to fix the brain damage caused by Alzheimer’s or Parkinson’s disease. The procedure would involve removing a small piece of testicle – about the same amount used for a biopsy. “We don’t need a lot of material,” says Dr. Marco Seandel, the lead author of a paper published Thursday in the journal Nature and a stem-cell researcher at the Howard Hughes Medical Institute in Maryland. His team’s work – and that of a German team also experimenting with stem cells extracted from testicles – is part of a growing international effort to look beyond the embryo for cells that can give rise to all human body parts and systems. Adults have small numbers of stem cells, too – in bone marrow, muscle and other tissues and organs. But these don’t seem to have the same superhero-like powers as embryonic cells. Stem cells in muscle give rise only to new muscle cells. Seandel and his colleagues didn’t reprogram the testicular stem cells with new genes. They put them in a special growth medium, and the cells returned to a state in which they could turn into many different cell types — not just the precursors to sperm cells. In live mice, the stem cells became part of a functioning blood vessel. In the lab, the scientists transformed them into brain cells, cardiac cells and muscle cells. There was a somewhat gruesome sign that testicular stem cells might turn into other types of cells quite easily. Testicular tumors, Seandel says, are sometimes found with hair, teeth or other tissue in them. The same is true for ovarian tumors, he says. But women don’t have the equivalent of sperm-producing stem cells. 160Want local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations!

Giants’ Posey hopes for minimum stay on injured list with hamstring strain

first_imgSAN FRANCISCO — In retrospect, Buster Posey thinks perhaps he shouldn’t have tried so hard to get an infield single.We last saw Posey on June 1, when the Giants beat the Baltimore Orioles 8-2 at Camden Yards. Batting against angular reliever Miguel Castro, Posey reached out and topped an infield grounder which was fielded by Orioles first baseman Trey Mancini.With Mancini’s momentum carrying him toward second, he turned and threw to Castro, who arrived at first base just before Posey.

A Hairy Evolution Story

first_img51; A mammal hair was found in amber.  It is claimed to be 100 million years old, but it is identical to modern mammal hair.  What is the meaning of this find?  How should it be interpreted?  It may say more about the modern evolutionist than about evolution itself.    New Scientist told the story.  The title read like a crime scene: “CSI 100 million years BC: oldest mammalian hair found.”  Romain Vullo at the University of Rennes I in France discovered the hair in a piece of amber (petrified tree sap) in southern France.  This is the oldest sample of mammal hair ever found, the article said.    Reporter Shanta Barley explained right off the bat that the evidence is plain and simple: “The scales on the hair – which provide its protective waterproof cover – are identical to those found on the hairs of mammals walking the Earth today.”  She reinforced the point later: “It turns out that the pattern is identical to that found on modern mammalian hair: rows of overlapping scales stacked on top of each other in an orderly fashion, with each row roughly 2 to 8 micrometres high.”     The scientists examining the hair had a little fun imagining what the animal was and how it died.  It might have been a small opossum-like animal, and it might have been running up a tree when it got stuck in the tree sap.  “Interpreting the ancient ‘crime scene’ where the hair’s owner died is fraught with difficulties,” Barley noted.  What’s really noteworthy is how to explain the hair being identical to modern hair after 100 million years of evolutionary time.  That’s where Vullo should have closed his mouth, because he just won Stupid Evolution Quote of the Week: “Perhaps mammalian hair does its job so well that it does not need to evolve.”Once upon a time, children, Hairy and Skinny were clinging to Mr. Opossum in the mystic forest.  Skinny looked at the fantastic array of dinosaurs, birds, mammals and reptiles around him, and thought, “I’m so plain and skinny.  I really need to reach my potential.  I need to stretch and learn new things.  Someday I’ll become covering for a whale or an elephant.  I’ll be a fat hippopotamus and develop my own sunscreen (05/25/2004).  I’ll cover fantastic creatures large and small.  My sensors will become so fine, they will rapidly move along the strings of musical instruments, and cover the scalps of philosophers!”  Hairy just laughed at all this.  “You dreamers and visionaries,” he said, “you always have your head in the clouds.  Don’t you realize how many mutations you are going to have to suffer through to wait for those things to emerge?”  Skinny sighed, deflated at the prospect.  “You should be like me,” Hairy said.  “I don’t worry.  I do my job so well, I don’t need to evolve!”    Cut, print, publish.  That’s genius.  That’s the thinking of a real scientist.  Children, aren’t you glad we have scientists to entertain us with stories of how we got here?(Visited 22 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

What the Trump Presidency Could Mean for Science

first_imgEditorial: a rising tide of economic prosperity could lift science, too, as long as it is honest science serving the citizenry.The morning after Donald Trump’s historic upset, his opponents in Big Science are strangely silent. They may be in shock. Some science news sites, like the BBC News, are panicking, worried what this will mean for global warming treaties. One guy on The Conversation is blaming Twitter bots for the victory. Mike Wall on Space.com is already telling Trump what he needs to do for space science. Science reporters will be analyzing the historic election for days and weeks, wondering what it portends for their interest group.There’s no question that scientific institutions were uniformly and shamelessly anti-Trump, as we reported (10/16/16). But the clear victory not only of President-elect Trump but the prospect of all three branches of American government leaning Republican, coupled with that election-night image of a red American map with just a few pockets of Democrat blue, should counsel the wise of the loyal opposition to avoid strident remarks at this time. Anti-Trumpism is impolitic right now for those hoping to get in the good graces of the populist revolution.Let’s consider some ways in which scientific institutions can be glad Trump won. His theme, “Make America great again,” if successful, will include science. The slow recovery over the last eight years, with its high taxes and unprecedented debt, has put a damper on everything. It’s not just coal miners and manufacturers who have been suffering. Science funding needs a robust economy that can generate tax revenue. When the gravy is plentiful, there’s more to go around. Big Science should welcome a strong American economy. Think of all the rhetoric about America falling behind in science. It’s not because of creationism, as Bill Nye is wont to complain. The whole country has been plodding along for nearly a decade. If you want strong science, make America prosperous again.Science has also suffered along with everyone else because of insecurity and instability over the past decade. You can’t have science without security. Will your lab fall victim to the next terrorist attack? Will violent student protests hit the science building? Can you have your next science conference without fear? The clearest responsibility of government is the safety of its citizens, and Trump has made the rule of law a priority. Law enforcement agencies are all on his side. If you want strong science, make America safe again.Honesty will help science. The journals have been fretting about fraud for years. Today on The Conversation, for instance, Marilyn McMahon called for tougher action on fraud. The ethics of a society flow from the top down. According to exit polls, the dishonesty of Hillary Clinton weighed heavily on voters’ minds. It seemed that political insiders could get away with things that would land ordinary citizens in jail. If she had won, her unscrupulous habits might well have tempted many a scientist to cheat, thinking that if our leaders can do it, we can do it. If you want strong science, make America honest again.Many conservatives feel chains dropping off after this election. Now that the pollsters, the pundits and the naysayers were proven wrong, there’s freedom in the air to say what one believes. Political correctness is trending downward. A light was switched on. The thought police look like pretenders in cheap Halloween costumes, less of a threat, less able to enforce conformity. How will that help science? Well, thought control tends to backfire on its enforcers. Science thrives on transparent, free exchange of ideas. Let’s talk. Let’s debate. Let’s listen to each other. If you want strong science, open up the marketplace of ideas.Trump is no scientist, but neither was Clinton. She said she “believes in science,” but she couldn’t tell a protein from a proton. What matters for researchers are the policies of the two candidates. Trump has promised to get rid of stifling regulations. While this will undoubtedly help small businesses, the air of individual liberty (under law) will have spillover effects on science. Excessive regulation hurts universities and research labs that, like businesses, have to spend inordinate amounts of money reading, understanding and complying with piles of paper orders written in incomprehensible legalese emanating from unelected bureaucrats. Imagine having more time and money to actually do science. If you want strong science, make America free again.We expect the secular Darwin-loving scientists to be fretting about a resurgence of creationism. No worries; if it happens, it won’t be because Trump pushes it. Most evangelicals had deep concerns about Trump’s paganism anyway. The President-elect hardly knows anything about the issue, although Vice President Pence might. Trump’s mind is focused on liberty and prosperity for all. The only possible challenges for evolutionists will be (1) needing to justify the expenditure of money on Darwinian research, (2) needing to defend Darwinism instead of assuming it. Trump’s call for school choice will, if implemented, decentralize schools and create more competition in the way science is taught. Public schools will still be guided by science standards adopted by state governments. But what if home schools and charter schools leave public school science education in the dust? Will the Darwin lobby retain the power to dictate what teachers must say about origins? Will a renewal of religious liberty empower Darwin skeptics to articulate their views more in public?We call on Darwinians to enter the debate. They may not be able to rest on their presumptive authority much longer. The consensus could shift in the new era of transparency (see 10/31/16). This is nothing to fear for a true scientist. Any theory that has to rely on consensus looks weak. If Darwinian evolution is solid, it can withstand scrutiny. Make your case. Show people the evidence. Give it your best shot. Good luck.For scientists who supported Hillary Clinton, have a good cry for a day, then think about these points. There’s no reason to fear. There’s every reason to embrace the future. If America is great again, science will be great again.—David Coppedge, EditorNature let loose with unmixed venom already. In a piece by Jeff Tollefson, Lauren Morello and Sara Reardon, the rag presumes to speak for all science by saying, “Donald Trump’s US election win stuns scientists.” Scientists? What scientists? All scientists? Some scientists? Globalist socialist UK scientists? Come on, that’s a very unscientific sample. We find out right away what they mean: scientists who push global warming agendas. One observer quoted thinks, “China could emerge as the global leader on climate change.” Wonderful. More power to them. Since they commit most of the pollution, let them clean up their act first. Then let them kill their economy by letting globalists tell them how to run their country.The editorial is also unscientific by calling him “the first anti-science president” as if Trump is opposed to capillary action, gravity or DNA. Good grief; this over-the-top hit piece is a slap in the face to the millions of Americans who voted for him. They quote only the most vicious Clintonians and Obamaniacs: “This is terrifying for science, research, education, and the future of our planet,” tweets a postdoc who wants to go back to Europe after the election. Please go, María Escudero Escribano. We’ll buy your ticket.Nature had none of the grace and humility that Trump showed in his acceptance speech. Even Hillary Clinton was magnanimous in defeat, calling all citizens to support Trump and give him a chance to succeed. Nature was nasty! Those pinko globalist materialists need to keep their grimy socialist claws out of American politics. They do not speak for all scientists. If science funding soars in a roaring Trump economy, we hope they will come trembling back like meek little kittens. In the meantime, an educational tour of their version of utopia would do them good. Venezuela. (Visited 44 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Moody’s rating: South Africa has plans to revive economy

first_img7 November 2014Moody’s decision to downgrade South Africa’s credit rating confirms the need for the country to implement growth-inducing initiatives.Responding to credit rating agency Moody’s Investor Services decision on Thursday, 6 November to downgrade South Africa’s credit rating from Baa1 to Baa2, National Treasury said the slowdown in the economy has spurred government to come up with measures to revive the economy.The Medium Term Strategic Framework, announced by Finance Minister Nhlanhla Nene in his 2014 Medium Term budget, is one such measure. The framework prioritises initiatives that will boost investment including major projects in rail, energy and ports.“Furthermore, focus in the medium term will be on accelerating the structural changes that are already underway and whose impact will support economic growth,’ said Treasury in a statement.Moody’s also revised the credit outlook for South Africa from negative to stable, retaining South Africa’s rating in investment grade. The agency said several factors informed its decision to assign the country a stable outlook and these include: South Africa’s position as the most developed country in Africa, offering by far the deepest capital marketThe country possesses one of the most sophisticated financial systems among emerging countriesIt has an economy that has a diversified productive base, with substantial value-added from domestic sourcesSouth Africa has highly advanced infrastructure compared with most emerging marketsIts institutions, especially the judiciary, are stronger than many of its peersHas recorded important milestones in the past 20 years which include the early establishment of macroeconomic policy credibility, expansion of services, housing and utilities and the emergence of the black middle class.In addition to the above, Moody’s said South Africa is committed to reigning in government debt growth over the medium term. The support that the National Development Plan (NDP) has received from the political sphere, introduction of tighter monetary policy and fiscal restraint will help stabilize the debt burden over the medium term, according to Moody’s.“The rating agency’s decision to assign a stable outlook to the current ratings affirms government’s commitment to fiscal discipline, which was reinforced by the recently published Medium Term Budget Policy Statement,’ said Treasury, adding that South Africa is committed to narrowing the budget deficit, stabilising debt and rebuilding the fiscal space that enabled the country to extricate itself out of the debilitating 2008/9 global economic crisis.Adding Treasury said South Africa will continue to implement “prudent’ macroeconomic policies which have been the hallmark of government since 1994.“Government will continue to make tough decisions that are necessary to address out challenges so we can build on the gains we have made over the past 20 years to improve the lives of our people,’ said Treasury.SAinfo reporterlast_img read more

Ayodhya verdict: Meerut police scan provocative social media accounts

first_imgAhead of the Ayodhya verdict, the Uttar Pradesh police are vetting social media accounts to spot trouble-mongers. Ajay Sahni, Senior Superintendent of Police, Meerut, has asked the cybercell team in the district to look into the accounts which make disparaging religious comments.Also read: Maintain peace after Ayodhya verdict: PM to Ministers“In the past 24 hours, we have taken down 10 such Facebook and Twitter accounts with the help of social media companies,” said Avinash Pandey, SP (Rural).Locals feel the move has come after Lakshmikant Vajpayee, former president of the Uttar Pradesh unit of the Bharatiya Janta Party, complained of a sudden rise in Twitter accounts in the name of characters of Hindu mythology. “We have noticed Twitter handles in the name of Shri Ram, Sita, Vibhishan and Ravan, where some of the conversations are insensitive to religious beliefs. I appealed to the IGP (Meerut Range) to look into the ‘real’ identities of persons who are running such accounts…,” Mr. Vajpayee told The Hindu.Mr Pandey said: “Four cybercell teams of our social media lab are working in rural areas as well. In the last few days, we have taken action in three cases. In one, a provocative comment was made against a Muslim religious leader, then an offensive statement was made against the Hindus, and the third talked of the exodus of families of one community. Such rumours of exodus keep cropping up in the region and we won’t allow them to gain traction.” However, he said there was no blanket ban on accounts with religious overtones.He said the police had a meeting with Army officials in the cantonment area on Wednesday to share military intelligence inputs.The administration is on high alert in the communally sensitive districts of western Uttar Pradesh. In Rampur, SSP Ajaypal Sharma held meetings with senior members of both communities in rural areas. In Saharanpur, District Magistrate Alok Pandey asked the district cybercell to scan social media for provocative posts and file FIRs against those spreading rumours on WhatsApp. Officials have been told to make it clear that not only those who generate provocative posts will be prosecuted but those who forward such posts will also be detained.In Bulandshahr’s Khurja, a mock drill with a drone was conducted.In Aligarh, Shehar Mufti Khalid Hamid said he would again appeal to Muslims after Friday prayers not to celebrate if the Supreme Court ruled in their favour. “We have full faith in the judiciary. I have sent a message to all local mosques that if the judgment is not to their liking, Muslims should not harbour ill-will towards the other community. Also, they should not fall for false propaganda and rumours on social media,” he told The Hindu.AMU Vice-Chancellor Tariq Mansoor has urged all sections to respect the verdict. “It is the duty of all sections to show the utmost respect to the decision of the highest court and not to give a statement or indulge in any activity which may vitiate the peaceful atmosphere on the university campus, in the city and in the country,” he said in a statement.last_img read more

BCCI moves HC against arbitrator’s stay to Royals’ termination

first_imgThe Cricket Board on Thursday moved the Bombay High Court against the arbitrator’s stay to the termination of contract with IPL franchisee Rajasthan Royals by it.The High Court will fix a date of hearing of BCCI’s appeal on Friday.Justice BN Srikrishna, who was appointed as arbitrator with the consent of both the parties, on November 30 stayed the termination saying that prima facie it was ‘illegal’.Meanwhile, in an other development, Kings XI Punjab today alleged before the High Court that the BCCI “deliberately” kept silent on arbitrator Justice Srikrishna’s disclosure that he might have to pull out of arbitration.The BCCI terminated franchisee contract with Kings XI too and this dispute has also landed in the High Court as Justice Srikrishna yesterday recused himself from arbitration.The former Supreme Court judge disclosed that he had once represented (as a lawyer) Bombay Dyeing, whose owner Ness Wadia has a stake in Kings XI. Following which, BCCI said that it had some “reservations”, and Srikrishna decided to pull out of the proceedings.But today, Kings XI lawyer and senior counsel Darius Khambata alleged that Justice Srikrishna had disclosed this fact on November 23, during arbitration proceedings between BCCI and Rajasthan Royals, but BCCI did not take exception to his acting as arbitrator in Kings XI dispute until yesterday.”BCCI kept silent deliberately… They strung us along for one week as the deadline for negotiating with ‘marquee players’ is to expire on December 6,” said advocate Khambata.Justice S J Vazifdar, who was hearing the case today, remarked: “The learned judge (Srikrishna) ought not to have recused.” .advertisementAs the High Court is going to hear both Kings XI’s petition, as well as BCCI’s appeal against arbitrator’s stay in Rajasthan Royal’s case next week, Kings XI today said that BCCI should postpone the date by which IPL franchisees are to submit list of contracted ‘marquee players’.As per the current schedule, teams are to conclude their contracts with four marquee players by December 6.Marquee players are the ones who had been with the franchisee for the previous three years. Every team can retain four marquee players, including a maximum of three Indians.After December 6, those players who have not been signed up by their existing team, can enter into contract with other franchisees.Kings XI’s case is that since its franchisee contract is terminated, it is at a disadvantage while negotiating with players.But BCCI lawyer advocate CA Sundaram said that the cricket body was not ready for this, though it was ready to postpone the next stage, when teams can start signing up remaining players, till December 10.Justice Vazifdar said he would pass order on this on Friday.last_img read more
