Fewer children mean longer life?

Mar. 27, 2013 ? New research into ageing processes, based on modern genetic techniques, confirms theoretical expectations about the correlation between reproduction and lifespan. Studies of birds reveal that those that have offspring later in life and have fewer broods live longer. And the decisive factor is telomeres, shows research from The University of Gothenburg, Sweden.

Telomeres are the protective caps at the end of chromosomes. The length of telomeres influences how long an individual lives. Telomeres start off at a certain length, become shorter each time a cell divides, decline as the years pass by until the telomeres can no longer protect the chromosomes, and the cell dies. But the length of telomeres varies significantly among individuals of the same age. This is partly due to the length of the telomeres that has been inherited from the parents, and partly due to the amount of stress an individual is exposed to.

?This is important, not least for our own species, as we are all having to deal with increased stress,? says Angela Pauliny, Researcher from the Department of Biological and Environmental Sciences at the University of Gothenburg.

Researchers have studied barnacle geese, which are long-lived birds, the oldest in the study being 22 years old. The results show that geese, compared to short-lived bird species, have a better ability to preserve the length of their telomeres. The explanation is probably that species with a longer lifespan invest more in maintaining bodily functions than, for example, reproduction.

?There is a clear correlation between reproduction and ageing in the animal world. Take elephants, which have a long lifespan but few offspring, while mice, for example, live for a short time but produce a lot of offspring each time they try,? says Angela Pauliny.

The geese studied by researchers varied in age, from very young birds to extremely old ones. Each bird was measured twice, two years apart. One striking result was that the change in telomere length varied according to gender.

?The study revealed that telomeres were best-preserved in males. Among barnacle geese, the telomeres thus shorten more quickly in females, which in birds is the sex with two different gender chromosomes. Interestingly, it is the exactl opposite in humans,? says Angela Pauliny.

The journal BMC Evolutionary Biology has classified the research article ?Telomere dynamics in a long-lived bird, the barnacle goose? as ?Highly Accessed?.

Do high natural gas prices mean the shale boom is ending?

High natural gas prices?seriously undermine the official story that the US has a century of cheap natural gas waiting for the drillbit, Cobb writes.

By Kurt Cobb,?Guest blogger / March 26, 2013

A crew works on a gas drilling rig at a well site for shale based natural gas in Zelienople, Pa. The present and the past suggest that the so-called shale gas revolution is about to end, Cobb writes.

As U.S. natural gas prices flirt with the $4 mark, some skeptics of the so-called shale gas revolution think prices are headed much higher. Such a move would, not surprisingly, seriously undermine the official story that the United States has a century of cheap natural gas waiting for the drillbit.

Several years ago when natural gas began flowing in great quantities from deep shale deposits beneath American soil, it seemed to be the beginning of the end of America?s troubled journey into dependence on energy imports?a journey marked by frequent worry, occasional war and enormous expense.

But, to some people this supposed solution to America?s energy needs has begun to seem as costly to the environment and human health as the country?s dependence on imported energy has been in terms of mental distress, money and blood. It turns out that this new kind of natural gas requires the industrialization of the countryside in order to extract it. And that, say those closest to the action, risks tainting air, land, and drinking water and compromising the health of humans and animals alike.

Well, at least we can say that shale gas is plentiful, cheap, American, and much easier on the climate than coal or oil. It didn?t take too long before people started looking into whether shale gas really was that much easier on the climate.?A Cornell University researcher came to the conclusion that shale gas was probably worse for climate change than coal. His conclusion hinged in part on what are called ?fugitive emissions??unintentional, but unavoidable releases of unburned methane into the atmosphere during the?hydraulic fracturingoperations performed to extract the gas. Methane is?some 20 times more potent?than carbon dioxide as a greenhouse gas.?

First Android-only 'Humble Mobile Bundle' now available

Today The Humble Bundle is introducing a mobile-only (and Android-only) "Humble Mobile Bundle", which is now available for your enjoyment. The Humble Bundle has been around for some time, and has also recently started including Android versions of games alongside Windows, Mac and Linux versions. This is the first time the bundle will only contain Android games, however. We recently reviewed each game in Humble Bundle 5 and came away impressed. This time around, we're looking at six great games:

  • Contre Jour
  • Anomaly Korea
  • Plants vs. Zombies
  • Bladeslinger
  • The Rooma
  • Metal Slug 3

If you're not familiar with the Humble Bundle system, it's a "pay what you want" model that lets you donate any amount you please and receive the first four games, and the last two games if you donate over the average. A portion of the proceeds also go to charity, which is great. The games are also DRM-free, which is a huge bonus. The average donation is currently $5.44, and you have just shy of two weeks left to donate yourself.

Ad Industry Attacks Against Mozilla Reveal Poor Choice of ...

The Interactive Advertising Bureau (IAB) and Association of National Advertisers (ANA) have launched a coordinated campaign against Mozilla in retaliation for the browser developer's Firefox?patch?that block cookies from any site that a user has not visited by default?("third party cookies"). But rather than mounting a campaign that attacks Mozilla directly,?IAB/ANA strategy is focused on scaring users by threatening more?advertisements.?

The rhetoric flowing from IAB and ANA is reminiscent of the 2012 presidential campaign - or the blather we now expect to hear following any ?given session of either branch of the US Congress; in fact, the sound bites from Computerworld's quotes from ANA's Dan Jaffe?and IAB's Randall Rothenberg are all too familiar:

"This is damaging to consumer interest and will undermine the Internet" - ANA

"It will cost jobs, and it will destabilize the ad-supported internet economy" -??IAB

"thousands of small businesses that make up the diversity of content and services online will be forced to close their doors" - IAB

"All users, no matter the browser they?re using, will lose access to independent websites produced by small businesses"?-?IAB

"Without third-party cookies, they [users] will see an increase in the irrelevant spam advertising served to them" -?IAB

Let's look at what the fear facts don't reveal.?

Third party cookies do afford users what Rothenberg describes as "robust, personalized experiences" but hardly with the "uncompromised sense of trust" he assures is present. Advertisers do not share information about how they are tracked with users or what parties are obtaining their behavior data, so there is hardly a basis for a user to assert trust or feel uncompromised.

Rothenberg claims that users "enjoy" personalized experiences. Mozilla claims that "users frequently express concerns about web tracking". ?In Suicide by Cookies, it's "stealing user data that can be monetized directly to ad buyers, or even resold in bulk data transactions via various exchanges."?Curiously, Rothenberg quotes a gamer site operator who claims that "30-45% of our readers use an ad blocker". This statistic is surely sufficent to at least suggest that users do not unilaterally trust third parties.?

Mozilla's Firefox patch will require that the user "must directly interact with a site or company for a cookie to be installed on their machine".?IAB/ANA claim users will see more advertising "spam" as a consequence. IAB/ANA really don't mean "spam" but "advertisements that are not based on prior user web behavior". This seems to be an admission that, like the MPAA and RIAA, online advertisers are more willing to defend a legacy business model than innovate.

?

Jaffe claims that Mozilla's patch will damage consumer interests. I'll generously assume he means that Mozilla is infringing on a user's right to choose what ads are displayed, but generosity aside, please go read the post or look at the privacy tab, Dan. Mozilla is changing the default and not preventing the user from choosing to see ads for all eternity. Yours is another case where opt-in triumphs over opt-out, with the predictable cry of foul from those whose businesses are based on intrusive rather than invited opportunity.?

John Boehner would be hard pressed to produce more dire - or less credible -predictions than the IAB/ANA. Mozilla cookie policies - or browser cookie policies, generally - are hardly all that separates small businesses from bankruptcy. People do and will search?for small businesses online. And they will not cease to consider advertising.?

Thousands of people in the soon-to-be destabilized ad-supported Internet economy won't lose jobs unless online advertisers choose to follow the course MPAA/RIAA have set. But even a long-time defender of cookie-setting and tracking like George Simpson observes, ?"I appreciate the economics of this industry, and know that it is imperative to wring every last CPM out of every impression -- but after a while, folks not in our business simply don't care anymore, and will move to kill any kind of tracking that users don't explicitly opt in to."

(AP) ? They mostly kept their distance, these supporters and opponents of gay marriage, as they massed Tuesday in front of the Supreme Court to proclaim with signs and slogans their conflicting views about the cutting-edge question before the justices.

People who favor legalizing same-sex marriage carried pictures of gay weddings and families and held signs that read "marriage is a constitutional right." They waved American and rainbow flags, and one man in devil horns danced in pink heels and a rainbow tutu.

Opponents, meanwhile, marched down a roadway in front of the court, hoisting placards including "Every child deserves a mom & dad" and "Vote for holy matrimony."

By the time the court began its session, which on Tuesday dealt with California's ban on same-sex marriage, the sidewalk outside was packed. Supporters spilled over to the other side of the roadway. "Gay, straight, black, white, marriage is a civil right," the crowd chanted at one point, followed by "we honor this moment with love."

Many supporters of gay marriage came with homemade signs including ones that read "a more perfect union," ''love is love," and "'I do!' want 2 B (equals)" Some signs had pictures of gay couples. "Together 34 years," read one, "married with pride," said another.

Gahan Kelley and Bonnie Nemeth, both 69, of Richmond, Va., had matching signs with their California marriage license on one side and a picture of their wedding ceremony on the other. The couple married in California during the 142 days when it was legal.

"This decision can change our lives tremendously," said Kelley of the Supreme Court cases.

Nemeth said she was hopeful that the court would support gay marriage.

"I really think we're going to win," she said.

Another couple, Stacey Parker, 37, and Debbie Sentner, 43, drove from Toledo, Ohio, to Washington to demonstrate. The pair married in Massachusetts in 2009, but their home state doesn't recognize their marriage. On Tuesday they carried signs that said "Tired of being a second class citizen" and "we the people means everyone."

"To us we feel married but we don't really feel complete until we can actually get all the rights and recognition that a lot of people take for granted," Parker said.

While many people were at the court to demonstrate, others stood in line to get inside the court to hear the arguments. Actor-director Rob Reiner, who helped lead the fight against California's Proposition 8, which barred gay couples from marrying in the state, was at the head of the line. Some people had waited since last Thursday ? even through light snow ? for coveted seats to hear the argument.

Supporters of gay marriage were initially the majority of the crowd standing outside the court, but a smaller group stood holding signs backing traditional marriage. Mike Krzywonos, 57, of Pawtucket, R.I., wore a button that read "marriage 1 man + 1 woman." Krzywonos, a retired metal worker, said his group is the "silent majority."

"The whole country does not want this," he said as helped hold a sign that read, "just because you don't get it does not give you the right to change it."

The crowd of opponents swelled just as the court began considering the case not long after 10 a.m. EDT. Opponents staged a march down the street in front of the court as supporters stood on both sides of the roadway. Some conversations between the two sides got heated, even with police escorting the group. Austin Ruse, 56, was one of the people who exchanged words with the other side, asking two women supporting same-sex marriage whether a man should be allowed to marry his adult son.

"If anyone can get married then marriage has no meaning," Ruse said later.

Christine Clark, 47, of Pittsfield, Pa., was participating in the march with her teenage children and their cousin. She said she knows and loves gay people but does not believe in gay marriage.

"We're not hating," said her daughter, Lydia Clark, 13.

Outside the court after the argument had concluded, supporters of same-sex marriage chanted, "Equal justice under the law," the motto inscribed on the face of the marble court building, and cheered as their attorneys, David Boies and former solicitor general Ted Olson, emerged from the court.

Boies called the arguments a "very thoughtful hearing." Asked if the court was ready to make a sweeping ruling, Olson said he had "no idea."

But Olson said public support is in favor of same-sex marriage.

"We are confident where the American people are going with this," he said. "We don't know for sure what the United States Supreme Court is going to do, but we're very, very gratified that they listened, they heard, they asked hard questions, and there's no denying where the right is and we hope that the Supreme Court will come out in that way when they make this decision in June."

Andrew Pugno, an attorney for ProtectMarriage.com, the group that defended Proposition 8 in court, said his side was able to say everything they wanted to during arguments and would look forward to the court's decision.

"I think that we'll see a very reasoned decision from this court," he said.

The court will hear one more day of arguments on the issue of gay marriage. On Wednesday the court will consider a case involving the federal Defense of Marriage Act, which defines marriage as between a man and a woman.
