Designer babies may explain insect sociality

Feb. 3, 2013 ? Being able to choose the sex of their babies may be the key to the complex societies built by ants, bees, and wasps, according to Oxford University scientists.

The researchers calculated the evolutionary costs and benefits to insect mothers of choosing the sex of their offspring and showed that, if females help out with bringing up babies, then mothers prefer to have daughters rather than sons -- leading to a large workforce of female helpers.

Their findings could also help to explain why termites, alone among social insects, have complex societies with a roughly equal balance of males and females: because in termite society both males and females help to raise offspring.

A report of the research is published in the March issue of the journal The American Naturalist.

'In social ants, bees, and wasps, mothers can decide the sex of their offspring by controlling which of their eggs get fertilized by sperm,' said Dr Andy Gardner of Oxford University's Department of Zoology, an author of the report. 'Fertilized eggs develop as daughters, and unfertilized eggs develop as sons. It's the daughters who do all the work in the colony, so this special ability means that the mother can raise a female workforce without wasting resources on relatively useless males.'

Previously, the sociality of ants, bees and wasps has been attributed to the curious fact that, in these species, a female is genetically more similar to her sisters than she is to her own daughters -- the so-called 'haplodiploidy hypothesis'.

However, this genetic quirk does not occur in termites, which have also evolved elaborate societies. 'The failure of the haplodiploidy hypothesis to explain the sociality of termites is one of the reasons why it has gradually fallen out of favour since being proposed in the 1960s' said Dr Gardner.

Co-author Laura Ross of Oxford University's Department of Zoology points out that termite sociality is, however, fully consistent with the new 'sex-ratio adjustment' hypothesis:

'Termites are the exception that proves the rule. They can't bias the sex ratio towards females, but they don't need to, because the males do as much work as the females in their societies. We suggest that the ability and need for sex ratio adjustment explains why some insects have evolved advanced eusociality and why other insects have not.'

Mayor's group sponsors gun control Super Bowl ad

A gun control group founded by New York City Mayor Michael Bloomberg is airing an advertisement during the Super Bowl calling for background checks.

The 30-second spot by Mayors Against Illegal Guns will air in the Washington area during the third quarter of the game between the Baltimore Ravens and San Francisco 49ers.

The ad calls on lawmakers to pass rules requiring background checks on guns. It is narrated by children, with "America the Beautiful" playing in the background.

It includes decades-old footage of National Rifle Association Executive Vice President Wayne LaPierre saying the gun lobby group approves of the checks. LaPierre recently testified before the Senate Judiciary Committee that the NRA no longer supports background checks for all gun sales.

A Bloomsberg spokesman would say only that the ad cost in the six-figure range.

Mayors Against Illegal Guns is a coalition of more than 800 mayors from 44 states.

Labrador Retriever Most Popular Dog in America; Ten Most Popular Breeds, Trends
Labradors stand tall as America's most popular dog breed

Here are the most popular dogs in America, at least according to American Kennel Club Registration numbers. Could this be a bit misleading? Sure, these days many people with pedigreed dogs don't bother to register, but still this is some gauge. No surprise, for 21 years now the Labrador Retriever continues to be America's most popular breed.

Most Notable Dog Trends in 2012 Include:

  • Mastiff-type breeds have risen in rank, with the Mastiff going from 34 to 26 and the Bullmastiff from 47 to 39 over the past decade, and the Cane Corso (67 to 60), Neapolitan Mastiff (116 to 112), and Dogue de Bordeaux (69 to 67) all making gains since the year they became recognized.
  • ?Bully? breeds have pawed their way into people?s hearts over the past decade with the Bull Terrier (79 to 51), Staffordshire Bull Terrier (91 to 76), and Miniature Bull Terrier (132 to 126) all making strong gains.
  • ?Dog owners are showing their love for Sporting Breeds over this past year as the Spinone Italiano (123 to 114), Boykin Spaniel (138 to 116), and Welsh Springer Spaniel (130 to 125) have all made their way up the list.
  • ?Small dogs that are on the rise this year are the Havanese (31 to 28) and Affenpinscher (139 to 138), while the Chihuahua (14 to 18), Pomeranian (17 to 19), and Pug (26 to 30) seem to have fallen out of favor.

PoppyFox: The fragmentation of motherhood

Tully just turned one month old this week and the time has just flown.

All those hours cuddling, feeding, on the couch reading +?playing with Miss Three,

eating and creating new family rituals.



The last few weeks have been sacred, joyful, life-altering, tedious + special spending it as a little family of four and yet it's been a little nuts. There have been times when l have felt fragmented and pulled in every direction. Being the mother of two children- you hold so many roles- the cleaner, cook, disciplinarian, carer, listener, kinder garden teacher, resident artist, story teller, mediator, juggler and miracle worker.

It's all new and a little overwhelming still.

Piecing together some sense of normalcy in our family nest has been a challenge but I'm getting there. I think whilst exhausted and a little sleep deprived I've coped even when I have felt like being in the trenches. That continual battle to find a moment for oneself, be happy and keep your head afloat, the family nest running, have dinner on the table and the kids happy. Sure there have been moments where tears, raised voices and a little crazy has featured but hey I'm far from perfect.

There have been changes for the better and some New Years resolutions for our tribe. The house has been reorganised and our possessions reduced. We still have a ways to go but so much has gotten done.

Gone are the days of waiting for Ads to come home from work to start dinner at 6:30pm. Dinner's now a 5:30pm affair after taking some very sound advice from a friend. I've achieved it three nights this week with the kids in bed by 7:30pm but it hasn't been easy. Tonight l had Miss Three going mental before dinner was served and falling asleep in my arms but you know you'll get that.

I've stopped feeling mother guilt over setting boundaries with Miss Three and being the disciplinarian, someones got to do it. I've spent more time talking to her honestly about our love for her and the need to teach her how to grow up + be good. I'm hoping she'll understand given time.

Our toilet training journey has been a great success with Miss Three rejoicing in her new found independence. She's a big girl now and she's wearing undies.

I'm proud of birthing such an incredible little girl. Her hugs have healing powers, her humor makes you laugh till your insides hurt and her smile makes my day. But talk about testing her limits I've had her in timeout so much her little couch has a permanent bum imprint from where she sits. And I've yelled so much I've loved that glass of wine when all is quiet late at night bugger what anyone thinks. Sometimes motherhood is just one big hard slog.

Oh the wonderful Three's.

I've also been working through the breastfeeding paradox. Having too much milk and a little baby boy that isn't drinking enough, it would be comical if I didn't have others pressuring me to take their advice. I mean WTF, 150 grams weight gain a week being what ideally a newborn has to put on and 130 grams just not being good enough. Miss Three was a small baby so pray tell why can't Tully and I find our own rhythm and let him set his own pace of growth.

He didn't want to wake up and feed when he was born. Then it was all about him not putting on enough weight + needing to express on top of his feeds + demand feed.

- it's all been a bit much.

I've nearly cried when dinners have been dropped off by friends - it always seems to be at a time when we just haven't been able to get around to cooking or things are going astray. Thank you to those that have cared for us. I know that having a newborn is a tremulous time where routines go out the window and you just grin and bare it. I also know it gets better. I've just got to hang in there and keep telling myself l am not a failure when it's not perfect or every one's not happy. I've just got to keep going, stay calm and it'll all be OK.

Reading several rather timely blog posts found here, here and here, photo sourced?here?about the many facets of motherhood has been a supportive, warm hug as I navigate my way through these early days. I salute you for your honesty, it's sometimes hard putting yourself out there;?it's caused a smile and much laughter. I know it's only been four weeks so one shouldn't expect things to have become routine but I'm mindful of the struggle when days don't go according to plan or design and I'm trying to enjoy the juggling act of motherhood because l love my little ones. I'm honest enough to admit that I'm happy but tired and dreaming of a little boy who feeds, a Miss Three who understands what quiet is and the chance to get a good night's sleep.

How do you all do it?

Nebraska Lt. Gov. Sheehy resigns after 'breaking public trust'

LINCOLN, Neb. (AP) ? Nebraska Lt. Gov. Rick Sheehy resigned abruptly Saturday in a scandal involving thousands of calls to four women on his state-issued cellphone, including one woman who said she had a romantic relationship with the politician.

Gov. Dave Heineman announced Sheehy's resignation in a hastily called news conference Saturday morning. Sheehy, a Republican, had been considered the front-runner in the 2014 gubernatorial race and had been endorsed by Heineman.

"As public officials, we are rightly held to a higher standard," Heineman said. "I had trusted him, and that trust was broken."

Sheehy resigned after questions were raised about the cellphone calls with four women, none of whom were his wife, who filed for divorce last year. The calls, made over the last four years, were first reported by the Omaha World-Herald, which had made a public records request for Sheehy's phone records.

Records released Saturday by the governor's office show Sheehy made thousands of late-night phone calls to the women. He spoke with some of the women numerous times a day in conversations that lasted anywhere from a few minutes to more than an hour, according to the records.

One woman he frequently called, Dr. Theresa Hatcher of Bellevue, told The Associated Press that she and Sheehy had maintained a long-term relationship after they met at a convention of emergency responders in Texas in 2008. As lieutenant governor, Sheehy leads the state's emergency management efforts, and Hatcher is an emergency room doctor.

"I thought I was the only one," she said. "Apparently, I was grossly mistaken."

Hatcher said she last talked to Sheehy about two weeks ago. She added: "Politicians can lie. Doctors don't lie."

Another woman Sheehy frequently called has had an apartment in Lincoln, the state capital. Her name appeared on a call box outside the building Saturday, but a man who answered the door said she didn't live there.

Sheehy was the mayor of Hastings before Heineman selected him as his running mate. They were elected by a record margin to their first full term in 2006 and re-elected in 2010.

Asked for his reaction Saturday, Heineman said, "I've got a knot in my stomach. I'm deeply disappointed."

Heineman said he doubted Sheehy would run for the governor's office now.

"And no, I would not support him under the circumstances," Heineman said.

Sheehy did not appear at the news conference, and his state-issued cellphone was disconnected. A phone call to Sheehy's office went unanswered, and a message was not immediately returned.

Last July, Sheehy's wife, Connie Sheehy, filed for divorce after nearly 29 years of marriage. Her divorce filing stated the "marriage of the parties is irretrievably broken."

Heineman declined to answer questions about what had occurred that led Sheehy to resign. He also would not say whether he asked Sheehy to resign or if Sheehy acted on his own.

Heineman said he will begin the process Monday of looking for a new lieutenant governor.

If something were to happen to Heineman before he selects a new lieutenant governor, Republican Speaker of the Legislature Greg Adams would ascend to the governor's post.

Sheehy's announcement shakes up an already turbulent 2014 governor's race. Another Republican candidate, former Nebraska Speaker of the Legislature Mike Flood, entered the race briefly but withdrew in December after his wife was diagnosed with breast cancer. State Sen. Charlie Janssen of Fremont, a Republican, has also said he is leaning toward running.

Several Democrats have signaled an interest in running, including University of Nebraska Regent Chuck Hassebrook and Nebraska state Sen. Steve Lathrop of Omaha. In recent weeks, party activists have also approached state Sen. Annette Dubas, of Fullerton.

"We're going to have a very strong candidate in 2014," said Vince Powers, chairman of the Nebraska Democratic Party. "This doesn't change anything, other than it really demonstrates that when you have one party in power for too long, arrogance and corruption and scandal follow it. It doesn't matter if it's Democrats in power or Republicans in power."

In an email to The Associated Press, Hassebrook said he is "taking a hard look" at running for governor in 2014.

"I recognize that no human is without failing. So I wish Rick Sheehy and his family the best as they seek to heal from this disappointing episode," he said.

Sheehy changed his Twitter account settings to private before Heineman's press conference. Shortly after, his account appeared to have been deleted.

96% West of Memphis

All Critics (71) | Top Critics (18) | Fresh (68) | Rotten (3)

Happy, sad, inspiring, infuriating, right and terribly wrong, all at the same time.

Berg's film is as much an indictment of the state of Arkansas' legal system as it is the prosecution.

Berg's film helps illuminate a case that should certainly be the shame of the state of Arkansas, and perhaps the criminal justice system of the entire United States.

Dubious evidence; suspicious confessions; conveniently located "poor white trash" (Echols' words) to take the rap: The case stank from the beginning, Berg's film argues.

Less an investigative report than a portrait of the community that forms around an ongoing court case, this conveys a patient understanding of the intricacies of law and human behavior that may be termed Kieslowskian.

"West of Memphis" is the fourth film about one of the most heinous cases of wrongful conviction in American judicial history. Do we need a fourth film? Yes, I think we do.

A frankly extraordinary document about the three innocent children who were murdered in West Memphis, Arkansas and the three innocent teenagers who spent 18 years in prison for the crime.

(Director Amy) Berg's doc is gripping, often infuriating, but in the end hopeful about the ability of truth and innocence to prevail thanks to the efforts of those who strive against all obstacles to uphold them.

The new film is largely a recap of the older ones, with more celebrity testimonials and fewer Metallica songs but little fresh insight into the miscarriage of justice it chronicles.

Extols the efforts of celebrities to win the release of three innocent men [and is] suspenseful when it's straightforward-the best CSI investigation that money can buy.

Nearly overwhelms you with hopelessness, if not an adrenaline rush of rage - even if you're familiar with the case.

It's a beautifully done piece of work in its own right, yet viewed beside the trilogy which preceded it, it comes across a bit like "Paradise Lost 3b - the Celebrity Edition."

A whodunit in which truth devastatingly becomes a luxury.

New evidence and a fresh perspective keep the subject matter compelling.

Filmmaker Amy Berg (Oscar nominated Deliver Us From Evil) has once again struck documentary gold with her hard-hitting journalistic feature, West of Memphis.

A lot of it is treading on ground that's been laid by other people, but there's a lot of great new stuff, too.

The infuriating facts in this famous case are illuminated with new human detail.
