  • "The Neighbors"

    <strong>"The Neighbors," ABC</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: One of the few "hits" of the season, "The Neighbors" has found an audience and kept it pretty steadily week after week (<a href="http://www.huffingtonpost.com/2012/06/11/abc-shows-fall-tv-2012-2013_n_1581796.html">much to our dismay</a>).

  • "Once Upon a Time"

  • "Revenge"

    <strong>"Revenge," ABC</strong> <strong>Status</strong>: On the bubble <strong>Why</strong>: "Revenge" has fallen out of critical favor and seen lower ratings in its new Sunday night home. But none of ABC's freshman dramas are doing well, so that works in the show's favor.

  • "Rookie Blue"

    <strong>"Rookie Blue," ABC</strong> <strong>Status</strong>: Renewed <strong>Why</strong>: The Canadian co-production will return for a fourth season on ABC during the summer of 2013.

  • "Suburgatory"

    <strong>"Suburgatory," ABC</strong> <strong>Status</strong>: On the bubble <strong>Why</strong>: The series started Season 2 off strong in the ratings, but its audience has slowly eroded. Its not the worst-performing ABC sitcom, but its buzziness has died down as well.

  • "Zero Hour"

    <strong>"Zero Hour," ABC</strong> <strong>Status</strong>: Too soon to tell <strong>Why</strong>: The Anthony Edwards vehicle debuted to 6.3 million viewers with a 1.3 rating in the key 18-49 demographic, making it <a href="http://www.huffingtonpost.com/2013/02/15/zero-hour-ratings_n_2695800.html">the least-watched premiere for a scripted series in ABC's history</a>.

    <strong>"2 Broke Girls," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: It's not doing "The Big Bang Theory" numbers, but "2 Broke Girls" has maintained a viewership over its two seasons.

  • "The Amazing Race"

    <strong>"The Amazing Race," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: As an Emmy and fan favorite, "The Amazing Race" has been a strong player for CBS.

  • "The Big Bang Theory"

    <strong>"The Big Bang Theory," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: Now in its sixth season, "Big Bang" is reaching series-high ratings. Even up against reality powerhouse "American Idol," "The Big Bang Theory" has been delivering with crazy high numbers in the 18-49 demographic, beating out what was once Fox's juggernaut.

  • "Blue Bloods"

    <strong>"Blue Bloods," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: The Tom Selleck-fronted police drama is a strong ratings performer for CBS on Fridays. It will likely be back to help launch new Friday shows and produce enough episodes to enter syndication.

  • "Criminal Minds"

    <strong>"Criminal Minds," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: As one of CBS's strong procedural players, the series has been steady in the ratings and will likely be renewed to help anchor a night and launch a new drama.

  • "CSI"

    <strong>"CSI," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: Of the two "CSI" shows on the air, "CSI" is the stronger player in the TV landscape. The show is nowhere near its earlier ratings, but after such a successful run, CBS would be smart to bring the show -- and some old faces back -- for an abbreviated farewell season.

  • "CSI: NY"

    <strong>"CSI: NY," CBS</strong> <strong>Status</strong>: On the bubble <strong>Why</strong>: The spinoff series will be entering Season 10 in the 2013-2014 season. The ratings have faded over the years, but they're still pretty stable, especially for Fridays. It's a toss up, depending on how well CBS's development slate goes.

  • "Elementary"

    <strong>"Elementary," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: One of the very few freshman series hits during the 2012-2013 TV season, CBS is very keen on this modern-day take on Sherlock Holmes. The audience has been steady and the network even gave it the post-Super Bowl timeslot.

  • "Golden Boy"

    <strong>"Golden Boy," CBS</strong> <strong>Status</strong>: Too soon to tell <strong>Why</strong>: CBS certainly has a handsome star at the front of this cop drama, but its late season entry and Friday timeslot could be a hint toward CBS's confidence in the show.

  • "The Good Wife"

    <strong>"The Good Wife," CBS</strong> <strong>Status</strong>: On the bubble <strong>Why</strong>: A former ratings champ, "The Good Wife" has slipped to series low ratings on Sunday nights. Blame football overrun, fan-detested storylines or too many guest stars, but "The Good Wife" is certainly in the danger zone. What it has going for it: star power and critical praise, plus its nearing a good syndication sweet spot.

  • "Hawaii Five-0"

    <strong>"Hawaii Five-0," CBS</strong <strong>Status</strong>: On the bubble <strong>Why</strong>: Its ratings -- bouncing around 8-10 million viewers an episode, are great ... if you're a show on NBC. By CBS standards, they're kind of meh, but this show has stars with very active fan followings. CBS could axe the drama to make room for new procedurals, or stick with it to get the show close to syndication gold.

  • "How I Met Your Mother"

    <strong>"How I Met Your Mother," CBS</strong> <strong>Status</strong>: Renewed <strong>Why</strong>: CBS handed out a ninth and final season to this comedy with the entire cast returning. Expect to meet the mother, finally.

  • "Made In Jersey"

    <strong>"Made In Jersey," CBS</strong> <strong>Status</strong>: Canceled <strong>Why</strong>: CBS pulled the plug on this legal drama very early on in the season because of low ratings.

  • "The Mentalist"

    <strong>"The Mentalist," CBS</strong> <strong>Status</strong>: On the bubble <strong>Why</strong>: "The Mentalist" has fallen to mediocre ratings -- by CBS standards -- and could be axed in favor of making room for a new drama.

  • "Mike & Molly"

    <strong>"Mike & Molly," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: The ratings are down a little bit from last year, but Melissa McCarthy's star continues to rise. CBS will likely bring the show back for another season.

  • "NCIS"

    <strong>"NCIS," CBS</strong> <strong>Status</strong>: Renewed <strong>Why</strong>: CBS reached a deal with series star Mark Harmon in early 2013, keeping the No. 1 show in America around for a Season 11.

  • "NCIS: LA"

    <strong>"NCIS: LA," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: Viewers love their "NCIS," in any form. The ratings have been strong and the network is producing a backdoor spinoff pilot for this spinoff show. A full night of "NCIS" could be in CBS's future.

  • "Partners"

    <strong>"Partners," CBS</strong> <strong>Status</strong>: Canceled <strong>Why</strong>: Low ratings and unfavorable reviews led to the <a href="http://www.huffingtonpost.com/2012/11/16/partners-canceled-cbs_n_2145832.html">early demise</a> of this CBS comedy.

  • "Person of Interest"

    <strong>"Person of Interest," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: The series has developed a nice-sized audience, bigger than its first season.

  • "Rules of Engagement"

    <strong>"Rules of Engagement," CBS</strong> <strong>Status</strong>: Honestly, who knows <strong>Why</strong>: This comedy has been on the bubble since it premiered ... yet is now in its seventh season. It's too soon to look at the numbers for this season, but the show has been a midseason success for CBS in the past. However, series co-star <a href="http://insidetv.ew.com/2013/02/07/cbs-orders-comedy-pilot-starring-patrick-warburton/">Patrick Warburton is attached to star in a new pilot</a> ... for CBS.

  • "Survivor"

    <strong>"Survivor," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: A strong player for the last 13 years, "Survivor" will likely be back. But due to its <a href="http://www.huffingtonpost.com/2013/02/14/survivor-ratings-lowest-premiere-ever_n_2687591.html">most recent premiere ratings</a>, we might not see it during the fall season, though a midseason or summer return -- with some new gimmick -- is definitely in the cards for the reality series.

  • "Two and a Half Men"

    <strong>"Two and a Half Men," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: CBS wants another season of this bawdy hit, it's just a matter of getting its stars to sign back on.

  • "Undercover Boss"

    <strong>"Undercover Boss," CBS</strong> <strong>Status</strong>: Likely to be renewed <strong>Why</strong>: The show is enjoying life in syndication and its Season 4 numbers are better than most of its third season.

  • "Unforgettable"

    <strong>"Unforgettable," CBS</strong> <strong>Status</strong>: Uncanceled <strong>Why</strong>: CBS canceled the Poppy Montgomery drama last season ... and then revived it! Season 2 premieres Sunday, July 28.

  • "Vegas"

    <strong>"Vegas," CBS</strong> <strong>Status</strong>: On the bubble <strong>Why</strong>: Despite star power, the series hasn't been a breakout hit in the ratings. CBS previously canceled "Unforgettable" (then uncanceled it) last season when it was doing about the same as "Vegas."

    Feds join civil lawsuit against Lance Armstrong

    WASHINGTON (Reuters) - Disgraced cyclist Lance Armstrong has failed to talk the U.S. government out of suing him to recover sponsorship money that the U.S. Postal Service paid his teams to compete in international events, Armstrong's lawyer said on Friday.

    Armstrong was stripped of his seven Tour de France titles and banned from cycling for life after accusations that he took performance-enhancing drugs. In January he said the accusations were true in an interview with television host Oprah Winfrey.

    "Lance and his representatives worked constructively over these last weeks with federal lawyers to resolve this case fairly, but those talks failed because we disagree about whether the Postal Service was damaged," lawyer Robert Luskin said.

    "The Postal Service's own studies show that the service benefited tremendously from its sponsorship - benefits totaling more than $100 million," the lawyer said in a statement.

    Former Armstrong teammate Floyd Landis was believed to have filed a sealed whistleblower suit against Armstrong in 2010. A decision by the government to join the suit would trigger its unsealing.

    A battle with the U.S. government over civil fraud charges would be a further fall in worldwide esteem for Armstrong. Criminal prosecutors have said they do not expect to charge him.

    A U.S. Justice Department spokeswoman had no immediate comment. Public court records did not indicate that a lawsuit had been filed as of mid-day on Friday.

    WHISTLEBLOWER LAW

    The government would sue under the False Claims Act, an 1863 law that encourages private individuals to file suit when they have evidence of fraud involving government money.

    When the government believes a suit has merit, it may take over the litigation. The individuals, or whistleblowers, get a portion of the proceeds if the case is successful.

    Since the law was revitalized in 1986, it has been used frequently against military contractors, pharmaceutical companies and hospitals.

    Armstrong is prepared to argue that claims over most of the sponsorship money are time-barred, a source close to his legal team said, speaking on condition of anonymity. The sponsorship agreement expired in 2004, and there is a six-year statute of limitations on recovery under a U.S. anti-fraud law, the source said.

    The source raised two other arguments that could help Armstrong. First, the sponsorship contract did not contain specific language or promises related to doping.

    Second, Armstrong was not in charge of Tailwind Sports, the racing team firm that signed the contract with the Postal Service and that existed before Armstrong joined it.

    Luskin is among the most sought-after defense lawyers in Washington. He represented former White House adviser Karl Rove in a case about the leak of a CIA officer's name.

    Chinese hackers have hit nearly every Washington institution, according to unnamed intelligence officials.

Hackers are particularly targeting Washington?s power base, Newser said. China continues to deny its involvement in cybersecurity warfare.

    America?s big hope, the unnamed intelligence experts said in the Newser report, is that China gets so much information that its hackers just can?t process it.

    Glowing shark's 'lightsaber' warning

    21 February 2013 Last updated at 09:04 ET By Rebecca Morelle Science reporter, BBC World Service

    A glow-in-the-dark shark scares off predators with "lightsaber-like" spines on its back, a study suggests.

    The research was carried out on the velvet belly lanternshark, a small species found in the deep waters of the Atlantic Ocean and Mediterranean Sea.

    The scientists believe that while the light-up spines can be seen by larger, potentially dangerous fish, they are harder for the shark's prey to spot.

    The study is published in the Nature journal Scientific Reports.

    Invisibility cloak

    This species of lanternshark (Etmopterus spinax) lives in the mesopelagic zone of the ocean, which has a range between 200m and 1,000m in depth.

    Dr Claes explains how the glow-in-the-dark shark can both hide and advertise itself using light

    It is a diminutive shark; the largest can measure up to about 60cm in length, but most are about 45cm long.

    Until recently, little had been known about this species, apart from the fact that like many deep sea creatures it has the ability to glow - a trait called bioluminescence.

    Previous research found that the shark has light-producing cells called photophores in its belly, and it uses this light to camouflage itself.

    "Imagine you are below the shark, the shark is swimming and you have the light from the Sun coming down," explained Dr Julien Claes, a shark biologist from the Catholic University of Louvain in Belgium, and the lead author of the study.

    "If you are just below the shark what you are going to see is a shadow. So imagine if the shark can actually produce a light, which is identical to the light produced by the Sun. Then the shadow of the shark is going to disappear."

    Any prey lurking below, typically a small fish called Mueller's pearlside, will not see the shark coming.

    However, this new study revealed that the shark is also luminescent on its top side.

    Dr Claes said: "There are two spines, one in front of each dorsal fin, and just behind them you have two rows of photophores. They are like lightsabers - they illuminate the spine.

    "It was surprising - why would you try to be invisible from below but visible from the dorsal side?"

    Warning beacon

    Visual modelling experiments revealed that potential predators could see the light from several metres away.

    The shark's prey, however, could only see the glow from a distance of about 1.5m, giving them less chance of making an escape.

    The team concluded that the glowing spines were acting as a beacon, illuminating the shark's threatening spines.

    Dr Claes: "It's a way to say: 'Don't bite me, I'm dangerous, I have spines on my back. You could be hurt.'

    "When you live in this dark place, what you try to do is avoid is to be seen by other animals, because there are no places to hide.

    "It can be very dangerous - you put yourself at risk when you produce light from your back, unless it acts as a warning system."

    He said it was unusual to find an animal that was using light to both hide and advertise itself at the same time.

    "It's surprising that these two apparently opposite behaviours can occur in a single organism at the same time. It is really paradoxical."

    issi sheep: Minister Ndebele builds relationships with other ...

    14 Feb

    The Correctional Services Minister Sibusiso Ndebele on Monday held a meeting with the senior leadership of the Police and Prison Civil Rights Union and the public servants association of South Africa in Tshwane, Geuteng. Minister Spokesperson Logan Maistry said the aim of the meeting is to strengthen relationships through regular engagements, with organised labour in the Department of correctional services. Maistry said the Minister found that South African prisons are the most overcrowded prisons in Africa.

    He added that they seek to share information and appreciate and recognise the role played by organised labour in supporting the transformation agenda of the crime prevention and security cluster.

    Sweat mutation may have helped us colonise Asia

    How did our species become the dominant one on Earth? Pinpointing the genetic changes that made this possible is one of the great challenges of evolutionary biology. Now, a team has developed a method that could allow us to reconstruct a detailed, step-by-step genetic history of our species spanning tens of thousands of years.

    As a first step, they have identified a mutation that arose in east Asia and then was carried over to North America as our ancestors crossed the Bering Strait and colonised the New World.

    "There is an archaeological record hidden in our DNA that can help point us to the traits that have been critical in human survival," says Pardis Sabeti of the Broad Institute in Cambridge, Massachusetts.

    Sabeti's technique identifies versions of genes that have been created by random mutation and then retained - because they give their owners some natural advantage over individuals who do not have the mutation.

    Gene variants that confer a survival advantage in this way can spread through a population ? a process known as natural selection. But genes can also mutate and then spread by random chance even though they provide no specific advantage. In 2010, Sabeti developed a test that distinguishes the two possibilities.

    The test works by looking for features that are associated with natural selection. For instance, when a gene spreads through natural selection, neighbouring stretches of DNA tend to also become more common, because they are attached to the favoured gene. So gene variants that have been selected for are often found surrounded by the same stretches of DNA, whereas those that have not been selected do not have consistent genetic neighbours.

    Sabeti has now examined the genomes of 179 people from around the world, and used her test to pinpoint 412 DNA regions that have been strongly selected for.

    The mutations in these regions represent key changes in human evolution over the last 40,000 years, after our ancestors first left Africa and were going global. The challenge now is to find out when each mutation arose, how it changed us, and why.

    Hair and sweat

    Sabeti's team made a start on this by examining the gene for the ectodysplasin A receptor (EDAR). Their analysis had revealed that one version of this gene, EDAR370A, is only found in some east Asians and Native Americans ? among whom it is much more common than the original EDAR. Based on its modern distribution, Sabeti calculated that the mutation that gave rise to EDAR370A arose in China around 30,000 years ago.

    To determine what changes the mutation brought about, she genetically modified mice to express EDAR370A.

    This produced a catalogue of transformations. The modified mice had thicker hair fibres ? as do Asians with EDAR370A. Their mammary glands also had smaller fat pads, which the team says may correlate with the fact that Asian women tend to have smaller breasts than African women.

    Perhaps most importantly, the mutant mice had more sweat glands on the pads of their feet. When the team examined 623 Han Chinese people, they found that those with EDAR370A also had more sweat glands on their fingers.

    Helpful mutation

    It's not clear why EDAR370A was selected for. Any one of the changes it produces could have been beneficial, or perhaps it was a combination of the effects. "You can come up with a good story for all the traits," says team member Yana Kamberov of Harvard Medical School in Boston.

    One possibility, the researchers say, is that the extra sweat glands helped humans to keep cool in the warm and humid Chinese climate of 30,000 years ago. That would fit with what we already know. Hunter-gatherers often bring down prey in long-distance chases, and being able to keep cool is essential for endurance running.

    Alternatively, it could be all about sex. Men in Asia may have found small breasts more attractive, and thick hair may have been desirable generally. Such sexual selection can have a powerful effect on populations.

    "I personally favour the idea that the traits could all have been acted on at different times," says Kamberov. She points out that the climate has changed dramatically since EDAR370A arose, so different effects of the gene may have been beneficial at different times. "It doesn't make sense to me that it was a one-hit wonder."

    It's always tempting to make up just-so stories about human evolution, says Ewan Birney of the European Bioinformatics Institute in Cambridge, UK. "Sabeti didn't do that." He adds that using mice to figure out exactly what the mutated gene does is a key advance on previous studies.

    Sabeti's work is the latest to identify genes that were important in the evolution of humans, and our subsequent history. In 2011, a study suggested that deletions of large chunks of DNA played a crucial role when the human family split from the ancestors of chimpanzees.

    More recently, the SRGAP2 gene was found to have duplicated 2.5 million years ago. The extra copies may have allowed our brains to grow larger.

    And within the last 70,000 years, interbreeding with Neanderthals gave us crucial immune genes that may have helped us go global.

    Research Efficiency and Reliability: An Exercise for Public Speaking

    An old television game show from the 1950s, Name that Tune, pitted 2 contestants against each other. The objective was for one contestant to name the tune the orchestra would play in fewer notes than could the other contestant. In this exercise, the objective is similar; it?s to find reliable information most efficiently, in as few mouse clicks or time as possible. For example, you might count the number of mouse clicks (or touches of a touch screen) as one point each. [Typing words into a search engine would be free and wouldn?t cost any points.] The more clicks you use, the less efficient your search. Another measure of research efficiency and one that would be easier to use in the classroom would be the time it takes to find the answer.?

    The learning objective here is for students to acquire efficient research strategies to find reliable information in an interesting and active way, in a way that will engage them rather than put them to sleep?as most discussions of research do. The exercise objectives are (1) to find a reliable answer to the question in as few clicks or in as short a time as possible and (2) to evaluate the source of the information.

    In a classroom, this can be set up in a number of different ways. For example, small groups can each be assigned one, two, or three questions and compete with one another in answering the question most efficiently, rather like Name that Tune. ?Or questions can be assigned to the class as a whole and students would compete against each other to try to find the answer first.

    After all the answers are found, discussion can easily center on what strategies are efficient and what strategies are inefficient. Those with greater research competencies will be teaching those with less competence. It?s the ideal learning classroom.


    The second objective is to evaluate the sources and the reliability of the answer found. Since most research will be done online and since anyone can ?publish? on the Internet, it?s especially important that the information not only be found efficiently but that the information should come from a reliable source. The accompanying table presents five criteria to use in evaluating research?built around the acronym FACQS to help you remember (fairness, accuracy, currency, qualifications, and sufficiency) the questions you?d want to ask about these criteria, and the precautions to take. These criteria and questions, of course, are relevant for evaluating research of all kinds (including information your receive from print media, from interpersonal interaction, from social media, or from film and television).

    ?
    Does the author of the material present the information fairly and objectively, or is there a bias favoring one position? Some websites, although objective on the surface, are actually arms of some political, religious, or social organization. It?s often useful to go to the home page and look for information on the nature of the organization sponsoring the website. Reviewing a range of research on the subject will help you see how other experts view the issue.
    Is the information presented accurate? [Although not always easy to determine, the more you learn about your topic, the more able you?ll be to judge accuracy.] Is the information primary or secondary? If it?s secondary information, you may be able to locate the primary source material (often a hot link in the Internet article or a reference at the end). Check to see whether the information is consistent with information found in other sources and whether the recognized authorities in the field accept this information.
    When was the information published? When were the sources that are cited in the article written? To ensure currency check important figures in a recent almanac, in a newspaper, or at a frequently updated source such as provides at the Federal Statistics website.
    Does the author have the necessary credentials? For example, does the author have enough of a background in science or medicine to write authoritatively on health issues? Do an Internet search to check on the writer?s expertise and credentials.
    Is the information presented sufficient to establish the claim or conclusion? The opinion of one dietitian is insufficient to support the usefulness of a particular diet; statistics on tuition increases at five elite private colleges are insufficient to illustrate national trends in tuition costs. The broader your conclusion, the more information you?ll need to meet the requirements for sufficiency. If you claim the usefulness of a diet for all people, then you?re going to need a great deal of information from different populations?men and women, old and young, healthy and sickly, and so on.


    ??????????? The third part of this exercise is public speaking. If the class worked in groups, one member of the winning group would explain?in a brief informative speech (2 or 3 minutes should be sufficient)?the strategies used to find the answer and how the reliability of the source was judged according to these five criteria. If the class worked individually, the winning student would give the brief speech of explanation. Groups or individuals that used a totally different research strategy might then compare their experiences with those of the winners. Or a symposium on efficient research strategies could be set up where a member from each group would explain in a brief speech the strategies used to find the answer and his or her group?s evaluation of the reliability of the source.

    Since students vary widely in their research competencies, the following questions vary in difficulty. Some are extremely easy and the answers are likely to be found in under a minute. Some are extremely difficult and the answers are likely to take a great deal longer.

    1.????? What is the ethnic population of Missouri?

    Reaction to State of the Union Address - Talk is Cheap

    Yahoo News asked readers and contributors to briefly respond to passages from Barack Obama's State of the Union address. Here's one reaction.

    Obama on gun violence: "It has been two months since Newtown. I know this is not the first time this country has debated how to reduce gun violence. But this time is different. Overwhelming majorities of Americans - Americans who believe in the 2nd Amendment - have come together around commonsense reform - like background checks that will make it harder for criminals to get their hands on a gun."

    My response: President Obama also said that "Gabby Giffords deserves a vote. The families of Newtown deserve a vote. The families of Aurora deserve a vote." In response to his proposals, I would say that our Constitution and countless thousands who have used firearms, including "assault weapons" to save their lives, the lives of their loved ones and property also deserve a vote! Re-instituting an assault weapons ban or even limiting the number of bullets a magazine can hold will simply ensure that only criminals will have these weapons, creating more victims. Give children the same protection we provide our politicians and put armed resource officers in every school rather than take away our right and ability to defend ourselves.

    Obama on the economy: "A year and a half ago, I put forward an American Jobs Act that independent economists said would create more than one million new jobs. I thank the last Congress for passing some of that agenda, and I urge this Congress to pass the rest. ? Our first priority is making America a magnet for new jobs and manufacturing."

    When President Obama was first elected, he promised that he would focus first on our biggest problem - the lack of jobs and the economy. He failed to keep that promise, meeting only rarely with his "jobs creation council" in four years. During that same time he's almost doubled our debt, making it more difficult for our economy to recover from the Great Recession and for hiring to resume. It is past time for him to stop blaming Bush and accept responsibility - he may not have created the problem, but his policies and inaction have contributed to prolong it. The President needs to realize that his talk is cheap when his actions don't back up his words.

    Obama on climate change: "I urge this Congress to pursue a bipartisan, market-based solution to climate change, like the one John McCain and Joe Lieberman worked on together a few years ago. But if Congress won't act soon to protect future generations, I will. I will direct my Cabinet to come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy.

    Like many Americans, I do believe that we need to take steps that will encourage businesses and individuals to do more to use and develop environmentally-friendly forms of energy. We have a legal process to accomplish this and other changes that should be made, through our Congress. It is past time that President Obama realizes he is not a "king" and he should stop issuing royal edicts and decrees through "executive orders" that bypass our legal process. Laws are created by congressional representatives who answer to the people to ensure that the will of the people is done, not the will of president or "king."

    Good Reads: A family in isolation, Pakistan's difficult present, Africa's biggest game

    In 1978, a group of Soviet geologists trying to land their helicopter in the taiga (thick wilderness) of remote Siberia saw startling evidence of human life. Soon they found the Lykov family ? who had been living in an encampment for more than 40 years with no contact with the outside world.

    Mike Dash, writing for Smithsonian.com, recounts their incredible story and the chance meeting that brought it to light. The Lykovs were Old Believers, a fundamentalist Russian Orthodox sect that had been persecuted since the days of Peter the Great. In 1936, after his brother was shot and killed by a Communist patrol, Karp Lykov took his wife, Akulina, and two young children and fled into the forest.

    For 40 years the family eked out a living in the unforgiving Siberian wilderness, ?permanently on the edge of famine.? Two more children were born. Akulina died of starvation in 1961 when a June snow destroyed the family?s small crop. The Soviet scientists were astounded to learn that the family had no knowledge of World War II, the moon landing, or any other major development of modern society of the past half century. The two youngest children had never seen a person outside their own family.

    RECOMMENDED: How much do you know about Pakistan? Take this quiz.

    But over the next few years, says Mr. Dash, as ?the Soviet geologists got to know the Lykov family, they realized that they had underestimated their abilities and intelligence.?

    The family at first spurned, then gradually accepted most of the modern technology they saw at the scientists? research camp nearby. When, during this period, three of the Lykovs died, scientists tried to convince Karp and his daughter Agafia to leave the wilderness, but they chose to rebuild their small cabin and stay on.

    After Karp died in 1988, Agafia, the youngest child, again refused to leave the life her family had forged ? and the only one she has ever known. ?A quarter of a century later, now in her seventies herself, this child of the taiga lives on alone, high above the Abakan.?

    PAKISTAN, A FORBIDDEN LOVE

    For Taymiya Zaman, Pakistan is not Osama bin Laden or blasphemy laws or drone attacks. It is her homeland, a place of rich culture and history, struggling under the weight of change and competing stereotypes. But for many people in the United States, where she is a history professor, Pakistan is a harbor for terrorists or the scene of poor brown children waiting for Western benevolence.

    Ms. Zaman?s rich personal essay appears in Tanqeed, an online magazine of politics and culture that focuses on Pakistan. Her essay first ran in the quarterly magazine Critical Muslim.

    Tired of the questions and accusations surrounding her nationality, Zaman ?builds a wall? around Pakistan. Finally, weary of the disconnect, and against the advice of her colleagues, she returns to Lahore for a sabbatical year. It will be the longest she?s been home since leaving for college 13 years earlier.

    She describes the homecoming: ?Landing in Karachi is like running into the arms of a lover you?ve been forbidden to see for years.? Once there, however, she gains ?the realization that I can?t hide from the things about being here that leave me troubled and edgy.? She is heckled by a bearded student who accuses her of disrespecting Islam. The traffic congestion is overwhelming.

    Zaman returns to her teaching position in San Francisco with newfound appreciation for the US and enduring love for her Pakistan. ?I know the newspaper images that fuel Pakistan-bashing. I know the minefields of personal sorrow and betrayal that don?t make it to newspapers. I also know a Pakistan beneath these images that is rich with extraordinary possibilities....?

    RECOMMENDED: How much do you know about Pakistan? Take this quiz.

    TAKE PHOTOS, NOT BIG GAME, ON SAFARI

    On Foreign Policy Blogs, Daniel Donovan writes of Botswana?s recent decision to ban big-game trophy hunting by 2014. Zambia followed suit soon after by banning hunting of lions and leopards.

    Botswana?s move has inspired both praise and criticism. In spite of short-term setbacks to the hunting industry, Mr. Donovan points to Kenya?s thriving nonhunting safari business as a sign of greater long-term economic gains in banning trophy hunting.

    ?While hunters and hunting advocates point to large profits being made in hunting of animals in Africa ... the reality is that photographic tourism far outdistances any money made in hunting safaris,? he writes. Big-game hunting in Africa has always held an allure for the rich and famous, but one study in Botswana showed that trophy hunting only represented approximately 0.1 percent of gross domestic product, as opposed to phototourism, which yields 11 percent. And as Zambia?s tourism minister, Sylvia Masebo, put it: ?Tourists come to Zambia to see the lion and if we lose the lion we will be killing our tourism industry.?

    Donovan concedes that ?[c]ritics of the decision argue that it will encourage poaching over the long-term,? which has reached alarming levels in Kenya. But ?even countries that encourage trophy hunting are not immune from illegal hunting,? as revelations of poaching violations in South Africa and Tanzania show.

    ?Ultimately, each country must decide which direction will benefit them both ecologically and economically.?

    Samsung details Innovation Centers in San Francisco and New York, focusing hard on software + hardware marriage

    Samsung

    David Eun, presently serving as EVP at Samsung's Open Innovation Center after stints at AOL, Google, Time Warner and NBC Entertainment, just took the stage here in Dana Point, California during the opening night of D:Dive Into Media 2013. Given the media / content focus of the event, the conversation between Eun and host Kara Swisher revolved almost entirely around Samsung's role in the world of content, production, connectedness and distribution. Starting things off with a bang, he affirmed that Samsung is opening two new Innovation Centers that'll act as idea accelerators. In a way, this is Samsung getting into the funding game, which certainly adds a new twist to an industry that has largely been dominated by angels that aren't necessarily a part of a major corporation.

    Initially, one will be opening up in the Bay Area, while the other gets planted at an undisclosed location in New York City. Eun noted that in the past, Samsung was "focused on manufacturing hardware," but it realized some time ago that you "have to get both hardware and software right." He stated that the company as a whole has been "investing quite significantly over the past few years on software," and turning to how it impacts content, he explained an internal company process that aims to gather insight about consumers. Not necessarily in the creepy, privacy-invading kind of insight, but in the way of discovering what consumers want, but don't yet have in the marketplace.

    Invisible tool enables new quantum experiments

    Invisible tool enables new quantum experiments [ Back to EurekAlert! ] Public release date: 11-Feb-2013

    Experiments on the quantum wave nature have enabled researchers to precisely measure tiny forces and displacements as well as to shed light onto the unexplored zone between the microscopic realm of quantum physics and our everyday world

    Matter wave interferometry has a long standing tradition at the University of Vienna, where the first quantum interference of large molecules has already been observed in 1999. Nowadays scientists are hunting down evidence for the quantum mechanical behavior of increasingly complex constituents of matter. This is done in experiments in which the flying of each particle seems to obtain information about distinct places in space, which are inaccessible according to classical physics.

    Synchronised laser flashes for quantum interferometry

    The quantum nanophysics team around Markus Arndt of the University of Vienna has now established a novel way of manipulating massive particles: the researchers use nanosecond long flashes of laser light to create gratings, three of which form a closed-path interferometer. This scheme allows creating quantum mechanical superposition states, which we do not observe in our macroscopic environment.

    When precisely synchronized, the fleeting light structures form a device freed from many constraints that limited the measurement precision in earlier machines. "Interferometry in the time-domain with pulsed light gratings will become a central element of quantum experiments with nanoparticles" states Philipp Haslinger who is the first author of the paper.

    Viennese prototype with powerful universality

    Five students from the University of Vienna have been planning and setting up the device over the past years. The developed prototype is one of a kind: for the first time it allows to investigate the quantum wave nature not only of single molecules, but also of clusters of molecules. During an experiment these particles line up for few nanoseconds in a periodic nanopattern. This structure may serve as a "nanoruler" which enables the detection of tiny external perturbations as well as the precise measurement of small forces and fields.
