June 19, 2013 ? When a new species emerges following adaptive changes to its local environment, the process of choosing a mate can help protect the new species' genetic identity and increase the likelihood of its survival. But of the many observable traits in a potential mate, which particular traits does a female tend to prefer?
A new study from the National Institute for Mathematical and Biological Synthesis finds that a female's mating decisions are largely based on traits that reflect fitness or those that help males perform well under the local ecological conditions.
Males' bright colors, flashy ornaments, and elaborate songs are examples of fitness-related traits that females appear to have evolved to prefer, according to the study, which appears in the journal Ecology Letters.
An example of these fitness-related traits can be found in the tropical Heliconius butterfly, where diverging color patterns on the butterflies' wings influence mate choice and hence divergence of populations. Another example are Darwin's finches, whose beaks evolved over millions of years with changes in birdsong, an important mating signal, and thus contributed to the rise of new and distinct finch species.
The study settles a long debate in evolutionary biology about the surprising commonality of traits that play a crucial role in both survival and mate choice. It was previously thought that such traits were uncommon and were thus named "magic traits." However, in unraveling the trick behind the so-called magic traits, the study predicts that these magic traits are far more common in nature than expected, and in fact, predicts that female mating preferences may reflect forces of natural selection that were in place during the origin of the species.
"Even if the link between survival and mate choice is not there to start with, it will probably evolve," said lead author Xavier Thibert-Plante.
Understanding the biological basis of mating behavior is important because it can shed light on how species boundaries are formed and maintained.
"Mating preference is crucial for the evolution of new species because it reduces, and may in some cases eliminate hybridization, which can produce offspring of mixed ancestry, slowing down or reversing adaptation and differentiation among emerging species," Thibert-Plante explained.

In one sense, the history of spam is the history of the Internet. It is a history of hackers who have constantly probed the limits of the Net?s capabilities to enable the medium to do their bidding in delivering all manner of electronic junk messaging. And it is also a tale of the scientists who have fought a constantly losing battle to try to stop them and, in the course of doing so, have helped shape the evolution of the Internet as a commercial medium.
What follows is a long chapter from a new book by Finn Brunton, a professor at the University of Michigan, that recounts the ceaseless battle of spammer vs. scientist. The book, as a whole, details the entire sweep of spam history, from the early pre-commercial era (through 1995), on to the frenetic cowboy years (?Nigerian Prince? fraud and ?pump-and-dump? schemes) until 2003 and the advent of spam legislation, followed by the subsequent globalization, criminalization and militarization that occurred from 2003 to 2010.
The chapter you are about to read, broken into four segments that will run today through Friday recounts the changes in the spam ecosystem after 2003 when, to deal with software filters and the new legal prohibitions, spammers created elaborate automated networks in some of the most far-flung regions of the globe to enable them to practice their trade unhindered. It turns out as well that these networks are becoming a linchpin of the inchoate cyberwarfare waged by national governments.
As Brunton notes in the introduction, spam is a product of our society, the work of ?programmers, con artists, cops, lawyers, bots and their botmasters, scientists, pill merchants, social media entrepreneurs, marketers, hackers, identity thieves, sysadmins, victims, pornographers, do-it-yourself vigilantes, government officials, and stock touts. He also phrases it slightly differently?and even more deliciously?elsewhere in the intro: ?a remarkable cast of postnational anarchists, baronial system administrators, visionary protocol designers, community-building ?process queens,? technolibertarian engineers, and a distributed mob of angry antispam activists.?
This book is a gem. The goings-on of the twisted personages who populate cyberpunk lit have nothing on the ingenious scheming of the spammers and the scientists dedicated to shutting them down. Read here and in days to come about this fascinatingly bizarre subterranean cyberworld. This first section deals with the elaborate, almost monastic scholarship that went into creating spam filters. (Links to previous excerpted segments will be available once new material is posted.)

One of the Curiosity rover?s designers, Stephen Pakbaz,?has created a LEGO version of the space-faring rover, which NASA calls the Mars Science Laboratory.
CUUSOO, which is usually translated from Japanese to either "imagination" or "wish," invites LEGO fans to pitch ideas for new products. Once submitted, models that have accumulated 10,000 votes from visitors to the CUUSOO site win review from LEGO for possible commercial release.
Mr.?Pakbaz, who goes by the username "Perijove" on the CUUSOO website, posted his rover submission to the website in November 2011. A mechanical engineer, Pakbaz was involved in some of the design and testing of Curiosity at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The LEGO rover garnered enough votes to qualify for review in August 2012, just weeks after the rover that inspired it landed on Mars.
Mr. Pakbaz said in his CUUSOO proposal that his goal was to design ?a LEGO model that was as faithful to the actual rover as possible in terms of accuracy, details, and mechanical function, while remaining at a reasonable size and cost.?
The real Curiosity rover is about the size of a small SUV, standing over 7 feet tall and weighing about a ton, according to Mr. Pakbaz's write-up. This LEGO version is one twentieth of the size.
Mr. Pakbaz said in his proposal that he has also designed the complicated descent stage equipment that LEGO may include in the commercial set.
?The product aligns well with the LEGO Group?s mission to ?inspire and develop the builders of tomorrow,? including those who will build our future in outer space,? said LEGO, on its website.
The rover was one of three projects that won CUUSOO review this summer. CUUSOO turned down one of them, a giant Star Wars Sandcrawler, and is still pending review of one based on the video game "Portals."
LEGO has not yet determined an expected release date or price for the rover.
The real Curiosity is still investigating on Mars and is slated to begin chugging about five miles over to the planet?s Mount Sharp this month.

Darling, can we talk?
iStockphoto.comA dapper older gentleman spurns his mate of a certain age to take a fresh-faced young lover. You've seen that movie before, right?
Well, this choice of youth may turn out to be more than a Hollywood trope. Researchers say decisions like that one may have been the evolutionary source of menopause.
While conventional wisdom says that men prefer younger women because they're fertile, a recent report in PLOS Computational Biology suggests that it's precisely this preference for younger mates that caused older women to become infertile in the first place.
A woman's probability of surviving beyond 40 years is much greater than the probability that she is fertile.
Courtesty of Jonathon StoneA woman's probability of surviving beyond 40 years is much greater than the probability that she is fertile.
Courtesty of Jonathon StoneComputational biologist Jonathon Stone of McMaster University in Ontario, Canada, spoke with Shots about the mathematical model he and some colleagues used to come up with that hypothesis.
First, for the sake of computation, they assumed that women have infinite capacity for both fertility and survival. Then, they slowly introduced common genetic mutations into the math mix and observed how those changes led women to become infertile and eventually die.
They were able to tweak the model to account for age preferences between mates. When they changed the program to allow men and women of all ages to mate, the data consistently showed that women's survival and fertility plummeted simultaneously.
It was only after they used mathematical trickery to adjust their program to skew toward a preference of men for younger women that the data showed a 20-year loss of fertility before death in older women.
The phenomenon of having several decades without fertility at the end of a woman's life is unique to humans. This period of life begins at menopause, and its origins have been confusing to researchers for years.
Until recently, evolutionary biologists had widely accepted the grandmother hypothesis, the idea that menopause evolved as a way for women to focus their energies on the youngest in the clan. "This idea," Stone says, "frees up daughters to have more offspring, an evolutionary advantage, since this increases the number of offspring twofold."
University of Utah anthropologist Kristen Hawkes, who wasn't involved in the mathematical research, says she has her money on the grandmother hypothesis. Hawkes, whose work deals with the evolutionary origins of menopause, points out that great apes, with whom we share a great deal of evolutionary history, exhibit a similar pattern of losing fertility in their mid-40s.
The difference is that while the apes' fertility rates seem to be in sync with those of humans, their longevity rates aren't. "They usually die before they get to those post-fertile years," she says. "They get to be old ladies, gray and frail, while they're still cycling."
But Hawkes acknowledges the human male's apparent difference in taste. "I agree the preference men have for young partners is a striking contrast with other primates ? especially since it is well-documented that chimpanzee males prefer older females," she says.
Stone says that the model also shows that the outcome could be reversed. "If we begin by assuming that all women are choosing to mate with younger men, male menopause will be the eventual evolutionary outcome." In fact, members of his team are currently testing this prediction in fruit flies, which reproduce rapidly enough to track evolutionary changes in next to no time.
What does this mean for us? Assuming this model is correct, if older women begin to eschew paunchy, balding partners in favor of younger mates, male menopause could become a reality in a few thousand years.

RICHMOND, Va. (AP) ? Fox News host Bill O'Reilly is taking his book-turned-movie franchise and running with it.
O'Reilly already has inked a deal with National Geographic Channel for the movie version of his book "Killing Jesus: A History" being published Sept. 24. And he's got three similar books in the works.
While he declined to divulge the topics, the upcoming projects will make "very, very dramatic history come alive on the page and then in the movies," O'Reilly said in an interview with The Associated Press on the Richmond set of "Killing Kennedy," the film adaptation of his book about President John F. Kennedy's 1963 assassination. The film featuring Rob Lowe as the former president and Ginnifer Goodwin as the first lady is expected to air around the 50th anniversary of the shooting later this year.
"We consider ourselves historical investigators," O'Reilly said of himself and researcher Martin Dugard. "We go and try to find new stuff and try to bring you a really vivid picture of who these people really were. ... I don't have an agenda at all, I mean I just want to know the facts."
In the beginning O'Reilly said the books were a "hard sell" to publishers, "but I said we're going to bring a different sensibility to it. And boom." The books have sold millions of copies.
The former history teacher also has published children's versions of his books because he was bothered that kids are "just not paying attention and not caring about history anymore."
"You have to force the urchins to look at their country and understand they're in America and here's what happened, and we're trying to make it fun for them to do it," O'Reilly said.
The film versions of his books have allowed O'Reilly to take on a behind-the-camera role, executive producing the movies. But he insists he's not a meddler.
"I'm a creative guy and I don't like meddling in my writing or my broadcasting," O'Reilly said. "They run stuff by me but I'm a 90-percenter ... they know what they're doing. It's a successful machine, so why do I want to muck it up? ... They can take a little bit of a creative liberty to move the narrative, but they can't change the facts. And it's as simple as that."
As far as his nightly TV program, the 63-year-old O'Reilly said he'll continue to do it "as long as it's worthwhile."
O'Reilly touted his program's ability to help raise money for charitable organizations as the one of the major motivations to stay on the air.
"I'm in it for that more than the self-aggrandizement at this point," he said. "I've proven what I had to prove. I still enjoy doing my job but it's a lot of work for an old guy."
