Parent induces guilt, child shows distress

Posted: 22 Mar 2013 06:07 AM PDT

The use of guilt-inducing parenting in daily parent-child interaction causes children distress still evident on the next day. According to a new study, the use of guilt-inducing parenting varied from one day to another. When parents used higher levels of guilt-inducing parenting on certain days, this was evident as atypically high levels of distress and anger among children still on the next day.

Risk of crime in gated communities

Posted: 20 Mar 2013 08:51 AM PDT

Gated communities are perceived to be safe havens in a world of risk and uncertainty, but new research from the United States challenges received opinion and suggests that, although opportunistic burglaries may be minimized, the risk of other crimes could be increased. The study, one of only a handful to investigate the crime statistics relating to these housing developments, reveals the unexpected reality behind the security gates.

First migration from Africa less than 95,000 years ago: Ancient hunter-gatherer DNA challenges theory of early out-of-Africa migrations

Posted: 22 Mar 2013 08:48 AM PDT

Recent measurements of the rate at which children show DNA changes not seen in their parents -- the "mutation rate" -- have challenged views about major dates in human evolution. In particular these measurements have made geneticists think again about key dates in human evolution, like when modern non-Africans split from modern Africans. The recent measurements push back the best estimates of these dates by up to a factor of two. Now, however scientists present results that point again to the more recent dates.

Spatial memory: Mapping blank spots in the cheeseboard maze

Posted: 22 Mar 2013 07:42 AM PDT

During learning, novel information is transformed into memory through the processing and encoding of information in neural circuits. Scientists have now uncovered a novel role for inhibitory interneurons in the rat hippocampus during the formation of spatial memory.

Hydrogen fuel? Thin films of nickel and iron oxides yield efficient solar water-splitting catalyst

Posted: 20 Mar 2013 08:52 AM PDT

Chemists say that ultra-thin films of nickel and iron oxides made through a solution synthesis process are promising catalysts to combine with semiconductors to make devices that capture sunlight and convert water into hydrogen and oxygen gases.

Certain bacteria suppress production of toxic shock toxin: Probiotic potential looms

Posted: 22 Mar 2013 09:54 AM PDT

Certain Streptococci increase their production of toxic shock syndrome toxin 1, sometimes to potentially dangerous levels, when aerobic bacteria are present in the vagina. But scientists have discovered certain strains of lactobacillus bacteria are capable of dampening production of that toxin.

Immune-cell therapy could strengthen promising melanoma treatment

Posted: 22 Mar 2013 07:43 AM PDT

Scientists have used newly developed nanotechnology chips (multidimensional and multiplexed immune monitoring assays) to successfully monitor T cells genetically engineered to attack melanoma. They have discovered that the T cells change over time when returned to patients. These results will help improve engineered immunotherapy for melanoma and the assays will help understand a spectrum of other cellular immunotherapies in the future.

Blocking an inflammation pathway prevents cardiac fibrosis, study suggests

F@%K It Friday: When Your Animal Dies, It’s OK to Grieve

Posted: 22 Mar 2013 03:45 AM PDT

Lucy_BWThis week is a sad week for me. Two years ago, Lucy died.

If I am honest about it, her death really broke my heart. I know that my feelings don’t make sense. Lucy was highly vocal, and I miss talking to her. And she was an easy roommate who never asked for much in return. How could I not miss that fuzzy gato?

I am writing about Lucy because I have a half-dozen friends who are caught up in animal grief, right now. Like me, many of them adopted cats and dogs in their 20s. This is the time in our lives when we lose our first pet.

So if you’re going through the pain and sadness of losing an animal, I can share this with you: It is very helpful to talk about it. Even though it might not make sense to some people, it is ok to remember the fun things you loved about your companion. And you can talk about this at work.

In my life, Lucy lives on through shared stories and memories. We talk about her all of the time. And I have two pictures of her in my house. Those pictures aren’t going anywhere.

I know that losing a beloved animal is so tough. I haven’t adopted any animals since I went through the experience of Lucy’s death, but I still believe in the lines from Alfred, Lord Tennyson:

I hold it true, whate’er befall;
I feel it when I sorrow most;
‘Tis better to have loved and lost
Than never to have loved at all.

Miss you, Spruce Goose.

It was worth it.

The Great Hog-Eating Contest

Christine Baumgarthuber | New Inquiry | 19 March 2013

Diet of 19C America South was simple and robust: pork, corn, whisky. “You see bacon upon a Southern table three times a day either boiled or fried.” No milk or eggs. Rickets, blindness, toothlessness common among rural families. "Farmers devoted precious acreage to tobacco and, later, cotton. Economic necessity trumped biological"

What Foster Parents Wish Other People Knew

Sharon Astyk | Casaubon's Book | 12 March 2013

"Kids in foster care have endured a lot of trauma. Sometimes that does come with behavioural challenges. But many of the brightest, best behaved, kindest, most loving children I’ve met are foster kids. They aren’t second-best kids, they aren’t homicidal maniacs, and because while they are here they are mine, they are the best kids in the world"

Looking Back On Iraq

Rory Stewart | Rory Stewart | 2 March 2013

"We have helped to create a place, which sometimes looks like a corrupt and fragile democracy, and sometimes like a Shia rogue state – somewhere on a scale between Iran and Pakistan. The question for Britain is what aspect of our culture, our government, and our national psychology, allowed us to get mired in such catastrophe?"

Talk Of The Irish

Daniel Menaker | New Yorker | 16 March 2013

"Having recently written a book about conversation, and having survived, at least for the time being, a serious illness that involved a huge number of grave discussions, and having lived seventy years’ worth of a life of words, I found myself at the end of last summer yearning to go back to Ireland, especially to the West, to hear the Irish talk"

Why I Have Quit Catholicism

Emma Keller | Guardian | 15 March 2013

"It is extraordinarily hard to bring your children up in a community with an entrenched tradition of pedophilia. It is almost impossible, as a mother, to stay connected to a church where thousands of children were abused, and the response of the men in charge, those you have trusted all your life, has been to cover the crimes up"

Afghanistan Withdrawal: What The Soviets Did Right

Sherard Cowper-Coles | Spectator | 15 March 2013

Before they left in 1989, the Russians installed a credible Pashtun strongman as leader, and told him to abandon socialism and embrace Islam. They asked neighbouring countries for help. The result was a regime that not only survived, but fought off the US-backed insurgency, until the Soviet Union itself collapsed. Can the West do as well?

Paul Krugman Is Brilliant, But Is He Meta-Rational?

Eli Dourado | Umlaut | 13 March 2013

Given that Paul Krugman has a Nobel prize in economics, should those of us who know far less about economics simply agree with whatever he says? Probably not. But it's a fair question. How can we evaluate the claims of people who are much smarter than we are? One way is to look at their conversational style. Pragmatists are wiser than dogmatists

The One-Legged Wrestler Who Conquered His Sport

David Merrill | Deadspin | 18 March 2013

Anthony Robles was born poor and one-legged in Mesa, Arizona. Bullied at school, chose wrestling to toughen up. Lost every match at first. Then he found the key: "Instead of balancing on one leg, he dropped to the mat, on two hands and a knee". Opponents were baffled. Four years later he was a national champion. Now he's quitting
