US lifespans lags other high-income countries, tied to mortality rates under age 50

Mar. 13, 2013 ? Higher mortality rates among Americans younger than 50 are responsible for much of why life expectancy is lower in the United States than most of the world's most developed nations.

The research, by Jessica Ho, a University of Pennsylvania doctoral candidate in demography and sociology, found that excess mortality among Americans younger than 50 accounted for two-thirds of the gap in life expectancy at birth between American males and their counterparts and two-fifths between females and their counterparts in the comparison countries.

The study is published in the March issue of Health Affairs.

Ho used cross-national mortality data from 2006-2008 to identify the key age groups and causes of death responsible for the U.S. life-expectancy shortfall.

Most of the excess mortality of those younger than 50 was caused by noncommunicable diseases, including perinatal conditions, such as pregnancy complications and birth trauma, and homicide and unintentional injuries including drug overdose, a fact that she said constitutes a striking finding of the study.

"These deaths have flown under the radar until recently," Ho said. "This study shows that they are an important factor in our life expectancy shortfall relative to other countries."

She said that the majority of the drug overdose deaths stemmed from prescription drug use.

Ho said her study underscores the importance of focusing on policies to prevent the major causes of deaths below age 50 and to reduce the social inequalities that lead to them.

Is Borax Really as Green as it Seems? | Care2 Healthy Living

By Sayward Rebhal, Networx

The Internet is rife with homemade ?green? cleaning recipes that seek to minimize toxic chemical exposure while saving money and maximizing environmental stewardship. Which is awesome.

However, many of these recipes include the ingredient borax, which until recently has been touted as an all-natural and eco-friendly cleanser. Borax is most often used to fight grease (like in dishwasher detergent) and as a ?natural? laundry booster (which is how it?s marketed ? you?ll find it in the laundry aisle). I even have a very popular borax-containing laundry detergent recipe on my own blog.

But in the latest edition of their Guide To Healthy Cleaning, the Environmental Working Group (EWG) gave Borax a grade of F ? ?Highest Concern?. And over on Enviroblog, a leading scientist for EWG cautioned people not to use borax-containing cleansers or cosmetics. Obviously, this came as a surprise to many of us in the natural-living community, and there?s generally been a lot of confusion ever since.

Unfortunately, the truth is that there?s still a lot of missing research, and a lot we simply don?t know about how borax affects human beings. Here?s what we do know:

What is borax?

Borax is, in fact, a naturally occurring mineral. It is one of the salts of boric acid, a boron-containing compound, and can also be found under the name sodium tetraborate.

Boric acid and it?s salts are used as pesticides, insecticides, fungicides, and wood preservatives. Sounds healthy, right?!

Well, it?s important to remember that the borax used to clean your home (and in some cosmetics) is not boric acid. They are similar, and similarly derived, but they are not chemically identical. Most of the studies referenced by the EWG and other agencies were performed using boric acid, not borax. Just something to keep in mind.

Is borax harmful?

The National Institute of Health calls boric acid ?a dangerous poison?. But that?s boric acid, not borax.

The FDA has banned borax as a food additive.

According to the EPA, boric acid/sodium borate salts are irritating to the skin and eyes and can cause acute toxicity when inhaled or eaten. The symptoms often include nausea, vomiting, skin rash, and respiratory distress.

The Borax Safety Data Sheet states that borax does not bioaccumulate in the body or biomagnify through the food chain. However, studies show that chronic exposure is associated with increased toxicity and more severe damage.

Most of the studies cited in the literature were performed on rats or other mammals, which makes it inappropriate to draw conclusions regarding human risk. It is believed that boric acid and its salts target the reproductive systems and can cause hormone disruption, especially in males. Human men working in boric acid-producing factories have increased risk of low sperm count and low libido.

Is borax eco-friendly?

Boron is an open-pit mined mineral. The process of open-pit mining involves drilling, excavation via explosives, heavy transport, and refining for purification.? It?s destructive, and fueled by petrochemicals. It?s not pretty.

However, it should be noted that 20 Mule Team Borax, the most widely available commercial product, is extracted in California at a mine that has been lauded for it?s environmental standards. It is considered to be one of the cleanest running mines in the world.

Still, remember that?s clean . . . for a pit mine.

America?s Environmental Protection Agency is still mostly neutral on it?s safety, but the European Union has flagged it as a ?Substance Of Very High Concern? and? Europe?s International Chemical Secretariat places borax on its SIN list of hazardous chemicals.

In conclusion

Upon reviewing all of this information, it seems that there is still some question as to the safety of borax itself (as opposed to boric acid) and it?s impact on human health. Therefore, the decision of whether or not to use borax in your homemade cleaning products will have to be a personal one.

As for me? I?m coming up with a new, borax-free recipe . . .

Kathy Gyngell - Conservative Home

Kathy Gyngell is a Research Fellow at the Centre for Policy Studies

Screen shot 2013-03-10 at 20.05.57Last week, Nick Clegg attacked what he defined as the outdated notion that men should go out to work while women stayed at home to look after the children.? He said the idea that the mother should be the primary carer ? even straight after the birth of her child - was frankly absurd.? ?It is the absurd Mr Clegg who is out of date and out of touch.

Next week, a group of highly intelligent and educated young mothers will be lobbying politicians to change such gender-equality driven childcare policies before it is, frankly, too late. They are concerned about the damage already done to children?s psychological welfare and to the institution of the family itself by state-prescribed care in cr?ches and daycare centres.

They abhor the bias against stay-at-home mothers that politicians like Nick Clegg advance and deeply resent their exclusion from the family policy debate ?and their marginalisation as unenlightened and old fashioned. They are neither. They are beleaguered. Understandably, they don?t want to upset working mothers. But they are right to insist that we can no longer ignore the evidence of large-scale studies in the United States and surveys from the UK and also Sweden, a country that has embraced daycare to such an extent that the mother?s right to stay at home has been virtually eliminated.? Sweden is on the brink of taking the family into state ownership.

In our feminist society, such mothers are treated as outcasts by the metropolitan progressive who dominate politics and the media.? As Dr Aric Sigman, an authority on the impact of daycare on young children, has said: ?If women?s rights have been hard won, so too has the ability to publish and discuss openly the inconvenient potential effects of daycare on children.?

The damage done to young minds and hearts has become the new taboo. It is still not discussed at the policy table, because it makes for such uncomfortable reading. If it is uncomfortable for the mothers corralled into work too soon (whether for financial or career reasons), it is even more so for feminists who drive universal childcare policy and for the politicians who?ve pushed childcare as an equal lifestyle alternative to mothercare. It is not. I found that out when I went back to work eleven weeks after the birth of my first baby. I struggled for a year against my maternal instinct before I had the sense and the strength to give into it and to look after my baby myself.?

At that time, back in the late 1980s, I had to resist the reassurances of such child care luminaries as Claire Raynor and Penelope Leach, who I was at the time producing on TV-am. They said I must not feel guilty about my return to work. Yet these were women who understood far better than most the infant?s need for maternal ?attachment?.? Such was the pressure of feminist thought even then.? They did though introduce me to a mass of child development literature, that gave me the confidence to make my mind up for myself and follow my heart.

Feminists said? that the post-war psychologist John Bowlby?s seminal works on attachment and maternal deprivation had been discredited.? I found them revelatory. I began to listen to my instincts, to understand that biological imperative for survival that my baby uniquely needed me.? Sacrificing children?s needs on the altar of feminism was short-sighted and not the route to fulfilment. So against the strongly feminist fashion of the time I opted to give up work become a stay-at-home mum. I was lucky to be able to afford to do so. Other mothers who later wrote to me at the time about their distress and anguish at having to go back to work were not so fortunate.

Since then the push for childcare has been relentless. Between 1990 and 2001, the number of? day nurseries, where children? as young as three months are parked for as many as nine hours a day,? leapt? from 87,500 to 285,100.? Today, thanks to Labour?s childcare subsidies (which now run into billions) and to the working and child tax credits they introduced (ones that discriminate against one-earner families) 57 per cent of 0-2s and 90 per cent of three to 3-4s? are now in some kind of formal childcare, ranging from childminders to day centres and nursery classes.

A disturbing 440,000 of 0-2s spend long hours in day centres ? 17 per cent of that age group. Now the Coalition government plans to have 40 per cent of all two-year-olds in day care by 2014 ? when they deem their ?education? should now start. Society must have an honest framework to review these policies ? policies which ought? be based on choice not dogma.? Mothers at Home Matter are pushing for this at an event at the House of Commons this week. It will be attended by the Swedish sociologist Jonas Himmelstrand.

He warns that Sweden, where 95 per cent of 2-5 year olds are put in day care, has witnessed a severe decline in child development and school performance.? Sweden?s universal childcare is not a model for other countries. Psychological disorders, including anxiety, have tripled since the 1980s, when daycare centres first began to feature heavily in Swedish child development. The childcare economic equation has not added up; as the state is unable to sustain its cost, quality has deteriorated dramatically. Early exposure to large groups of peers has detrimentally effected the psychological maturation of children and young people, learning and the transference of culture between generations. ?It is?, he says, ?at the root of bullying, teenage gangs, promiscuity and the flat-lining of culture.?

We can already see frightening similarities here where even teachers of nursery classes are finding discipline a challenge. Leading UK child psychologist Oliver James explains: ?Early care sets our emotional thermostat. Having a responsive mother who is there for the child in the early years is the best possible care?..Studies show that day care is less good for under three year-olds than child minders, who are less good than nannies, who are less good than close relatives, who are less good than parents.? He knows, as do other child psychologists and sociologists, that these findings are not unique to Sweden.

Professor Jay Belsky was involved for more than fifteen years with the most intensive investigation into the effects of childcare ever which followed some 1,000 American children growing up in 10 locations across the USA, from birth to age 15 (called the NICHD Study of Early Child Care and Youth Development).? It revealed a clear and definitive association between early and extensive child care experience, especially center-care exposure, with what psychologists describe as ?externalizing behaviour? problems? including aggression, from two years old through to the child?s 11th year, regardless of family background or other factors.

He also reported the contagious effects of childcare later in the classroom: ?The more children there were in kindergarten classrooms that had extensive histories of child care, especially in centers, the more aggressive and disobedient were all the children in the class. ...even children with limited child care experience could end up behaving more like children with lots of child care experience than like other children with limited child care experience if they were in classrooms made up of lots of children with early and extensive child care histories.?

Nor can the effects of childcare on behavior be put down to American culture.? In the UK too, children who spent more time in group care, mainly nursery care are more likely to have behavioural problems, particularly hyperactivity, than home cared children; and? that under-twos who spent long hours in day care were more likely to exhibit anti-social behaviour when they start school. These were the findings of the authoritative Family Children and Childcare Study.

All these findings make it clear that we disregard the feelings and the experiences of our infants at our peril. Nor is it just the children we need to watch out for, but mothers too, who are constantly pressured to relinquish responsibility for their nurturing role.? Swedish mothers who, like here, largely find themselves in low paid jobs often( ironically, looking after other women?s children) take more sick leave than in any other country in Europe, despite the generous 12 month maternity leave they are initially given.?

When asked why they opt for the highly subsidised state childcare they cite the punitive tax system where, like here, a single-earner family pays more in tax than its dual-earner equivalent, taking the childcare subsidy into account. They want to spend more time with their infants and children.

Yet Nick Clegg says; ?It?s heartbreaking to watch women who feel forced to lower their ambitions for themselves. And it?s heartbreaking to see fathers missing out on being with their children.? What is heartbreaking is that he, like so many politicians today, is so blind to children?s real needs ? and that his childcare policies are so dogmatically cast through the prism of adult sexual politics and women?s rights.

Lunar impacts created seas of molten rock

Mar. 11, 2013 ? A new analysis of data from NASA's Lunar Orbiter Laser Altimeter (LOLA) shows that molten rock may have been present on the Moon more recently and for longer periods than previously thought. Differentiation -- a settling out of rock layers as liquid rock cools -- would require thousands of years and a fluid rock sea at least six miles deep.

Early in the Moon's history an ocean of molten rock covered its entire surface. As that lunar magma ocean cooled over millions of years, it differentiated to form the Moon's crust and mantle. But according to a new analysis by planetary scientists from Brown University, this wasn't the last time the Moon's surface was melted on a massive scale.

The research, led by graduate student William Vaughan, shows that the impact event that formed the Orientale basin on the Moon's western edge and far side produced a sea of melted rock 220 miles across and at least six miles deep. Similar seas of impact melt were probably present at various times in at least 30 other large impact basins on the Moon.

The research is published in the April issue of the journal Icarus.

Vaughan and his colleagues show that as these melt seas cooled, they differentiated in a way that was similar to the lunar magma ocean. As a result, rocks formed in melt seas could be mistaken for "pristine" rocks formed very early in the Moon's history, the researchers say.

"This work adds the concept of impact melt magma seas to the lexicon of lunar rock-forming processes," said planetary geologist James W. Head III, the Scherck Distinguished Professor of Geological Sciences and the senior researcher involved in the study. "It emphasizes that one must consider the detailed point of origin of the rocks in order to interpret them correctly."

That includes rocks brought back during the Apollo program and Russia's Luna missions. It's quite possible, the researchers say, that impact melt material is present in lunar samples thought to be representative of the early formation of the lunar crust. The amount of rock formed in melt seas is far from trivial. Vaughan and his colleagues estimate that impacts forming the Moon's 30 large basins produced 100 million cubic kilometers of melt, enough to make up 5 percent of the Moon's crust.

If lunar samples do include melt material, it would help to explain some puzzling findings from lunar samples. For example, in 2011 an analysis of a sample assumed to have originated in the early lunar crust suggested that the sample was 200 million years younger than the estimated time when the lunar magma ocean solidified. That led some researchers to conclude either that the Moon is younger than previously estimated or that the lunar magma ocean theory was flawed. But if that sample actually originated from a melt sea, its young age could be explained without rewriting the history of the Moon.

The melt sea at Orientale

The Orientale basin is only partly visible from Earth on the western edge of the Moon's near side. Because it's one of the few basins on the Moon that hasn't filled in with volcanic basalt, it provides a great place to investigate the geology of melt seas and to test whether they differentiate as they cool.

For the Orientale melt sea to have differentiated, it must have been liquid for a long time -- thousands of years. To be liquid that long, it must have been quite thick. That left the researchers with a question that wasn't easy to answer: How thick was the Orientale melt?

"In pictures, you're just seeing the top of an impact melt body, so we have to find a way to infer how thick it was," Vaughan said.

To do that, Vaughan and his colleagues took advantage of the fact that a liquid shrinks when it cools and solidifies. Data from the Lunar Orbiter Laser Altimeter (LOLA) showed that the sheet had subsided by about two kilometers from the surrounding rock, giving the researchers an idea of how much the sea shrank. With that data, they could calculate its volume and infer its depth.

According to the calculations, the Orientale melt sea must have been at least 10 kilometers thick. Far shallower melt sheets from impacts on Earth are known to have differentiated, so it's a safe bet that Orientale was thick enough to differentiate.

The next question was what that differentiation might look like. Based on the compositions of the lunar crust and mantle material melted, Vaughan could determine the composition of the impact melt sea. From there, he could make a model of what rocks would have formed as the melt sea cooled. According to the model, thick layers of rocks like dunite and pyroxenite form at the base of the melt sea from dense, early crystallizing minerals that sink through the melt. Other minerals float up through the melt to form layers of rocks such as norite at the top of the melt sea -- very similar to differentiation processes in the lunar magma ocean.

Vaughan's model is supported by remote sensing data from the Maunder crater, the remnant of an impact that excavated material from the melt sheet after it cooled. The data confirm a noritic composition at least four kilometers deep in the melt sheet.

Taken together, the findings suggest that impact melt seas produce rock in a way that's very similar to the lunar magma ocean. And that could help to clear up some lingering questions about the magma ocean paradigm.

"This is a mechanism by which the Moon was later modified to add petrologic complexity," Vaughan said. "It helps make sense of mineralogical data that doesn't always fit in this lunar magma ocean idea."

Spymaster's Orcasub is a $2 million submarine for two

Spymaster's Orcasub is a $2 million submarine for two

Sure, you could use an ROV to feel like a regular Jacques Cousteau (or James Cameron, for that matter), but nothing beats the real deal: a personal submarine. UK department store Harrods used its Technology Showcase 2.0 event to highlight a mockup of Spymaster's Orcasub: a made-to-order $2 million submarine that can drop up to 2,000 feet into the briny depths. A total of two passengers can climb aboard the 4-ton, 22 foot-long submersible thanks to a pair of 360-degree domes that offer 80 hours of life support for each occupant. The battery-powered sub is piloted by using two foot pedals and a joystick, and handles somewhat like an aircraft since it was built with the principles of flight in mind.

Orcasub comes outfitted with sonar for collision avoidance, a digital long-range communications system and a 60,000 lumen LED lighting rig. What you see above is just a miniature, but Spymaster is taking orders for the real, full-size McCoy. In fact, folks who'd like to dive deeper can put in a request for pricier models, with the most expensive version nabbing explorers a maximum depth of 6,000 feet for a cool $9.32 million. If you ask us, this sounds like a perfect escape vehicle for any luxury yacht worth its salt. Hit the source link for Pocket-lint's photo gallery of the craft.
