Chinese Have Hard Questions About School Safety

Thu May 29, 2008 at 11:22:58 AM PDT

In California, one of the pesky things about building a new school or hospital is that building codes are very very strict, even stricter than for ordinary buildings. The ground must be firmly compacted to a standard far higher than ordinary construction. The building must be constructed to withstand the forces of a large earthquake.

People planning or paying for such buildings often grumble about the added hassle and expense.

Sadly, the Sichuan earthquake in China graphically and horrifically demonstrates why those rules are in place.

NY Times - Chinese Are Left to Ask Why Schools Crumbled:

DUJIANGYAN, China — The earthquake’s destruction of Xinjian Primary School was swift and complete. Hundreds of children were crushed as the floors collapsed in a deluge of falling bricks and concrete. Days later, as curiosity seekers came with video cameras and as parents came to grieve, the four-story school was no more than rubble.

In contrast, none of the nearby buildings were badly damaged. A separate kindergarten less than 20 feet away survived with barely a crack. An adjacent 10-story hotel stood largely undisturbed. And another local primary school, Beijie, catering to children of the elite, was in such good condition that local officials were using it as a refugee center.

“This is not a natural disaster,” said Ren Yongchang, whose 9-year-old son died inside the destroyed school. His hands were covered in plaster dust as he stood beside the rubble, shouting and weeping as he grabbed the exposed steel rebar of a broken concrete column. “This is not good steel. It doesn’t meet standards. They stole our children.”

There is no official figure on how many children died at Xinjian Primary School, nor on how many died at scores of other schools that collapsed in the powerful May 12 earthquake in Sichuan Province. But the number of student deaths seems likely to exceed 10,000, and possibly go much higher, a staggering figure that has become a simmering controversy in China as grieving parents say their children might have lived had the schools been better built.

Childhood Cancer Survivors

Mon May 26, 2008 at 10:49:55 AM PDT

Today, nearly 80% of children who get cancer survive - a fantastic success. However, chemotherapy and radiation have significant long term effects. Now that the first waves of survivors are reaching middle age, doctors have a lot more information about the health issues these children face. From the Los Angeles Times:

Doctors are using the experiences of these young survivors to try to make things better for new generations of pediatric cancer patients. They are also coming to realize they must do better by young people whose cancer lies behind them. Only recently is the medical community understanding the importance of lifelong health monitoring to help them avoid, or detect early, the host of medical risks that could lie in their path.

Massive Chinese Earthquake

Mon May 12, 2008 at 10:40:15 AM PDT

A massive earthquake hit central China today, at roughly 2:30 pm local time, measuring 7.9 on the Richter scale. This is a very dangerous earthquake and would cause substantial damage and loss of life even in developed nations with advanced building codes. I'm not familiar with this area of China or its architecture, but I've been told it has a great mix of structure types - simple stone buildings to wood frame buildings to modern high rises. The earthquake was felt 1,000 miles away in Bejing and Shanghai - an astonishing distance of the sort seen in the US for the New Madrid region, but unheard of in California.

The earthquake was in the foothils of the Himalayas, within 50 miles of a major city, Chengdu, located in the basin below. A school has collapsed, killing some children and trapping many more. Thousands are reported dead.

USGS has recently upgraded this earthquake from the original 7.5 to 7.9 magnitude. The USGS link includes maps and other data.

Enjoying Astronomy

Thu Apr 17, 2008 at 08:12:20 AM PDT

The LA Times has a travel story this week about Ten Great Observatories of the West. To be fair, this isn't really a list of great observatories for science, but great observatories for the public, institutions that allow people to visit and take a look through a live telescope. Their listings are California-centric, but include Mt Wilson, Griffth Park Observatory, and Big Bear Solar Observatory in southern California; Lick Observatory in Northern California;  Jack C. Davis Observatory in Nevada; Goldendale Observatory in Washington; Mt Graham, Lowell Observatory and Kitt Peak in Arizona; and McDonald Observatory in Texas.

(A tip, from friends of mine who have worked there: don't ask at Big Bear Solar Observatory, which only studies the sun, if they take observations at night. They don't. :-) )

In general, you won't be able to look through the flagship instruments at these observatories (those don't tend to have eyepieces at all any more), but there's still something quite special about looking through an enormous glass instrument and seeing a cluster of stars revealed, or Mars, Jupiter, or Saturn live and in person. The image you see won't look like the beautiful false-color images taken by Voyager - indeed, it's amazing to look through instruments far more powerful than anything Galileo ever had and wonder how he found all the moons that he did. It takes years of practice to be able to discern some of the faint details, such as the lines on Mars once thought to be signs of intelligent life. (I believe the telescope Percival Lowell used for those observations, as well as the discovery of Pluto, is one of the ones used today for public viewing.)

The Bake Sale, Supersized

Thu Apr 10, 2008 at 01:47:12 PM PDT

In California, parent organizations are doing everything they can to try to save teacher jobs, including attempts to raise extraordinary amounts of money. Ivanhoe Elementary, in the Los Angeles Unified School District, is attempting to raise $180,000 to save three teacher positions.

As Steve Lopez writes in the LA Times:

Get out your checkbooks, parents were told. All those wrapping-paper sales and pancake fundraisers wouldn't be enough. We could either pony up some hard cash, or see Ivanhoe's standing as one of L.A. Unified's best schools.

Pay $25, if that's all you can afford, Herman said. But he pointed up to a screen encouraging parents to dig a little deeper. Those three jobs can be saved, he said, if 80 parents contribute $250 apiece, 75 contribute $500, 50 fork over $1,000, 20 give $2,000 and six bust the bank with $5,000 contributions.

It's unconscionable. And of course, not every school has the resources to raise even $1800, let alone $180,000.

A Republican member of our school board was saying, gee, Gray Davis wasn't so bad after all. That's when you know things have gone mad.

Sleep Deprivation and Health Effects

Mon Mar 17, 2008 at 04:36:01 PM PDT

We've talked a lot here about sleep, and here is a piece from 60 Minutes talking about just how critical sleep is, and how dangerous sleep deprivation can be:

One thing that's clear, says Walker, is that sleep is critical. In a series of studies done back in the 1980s, rats were kept awake indefinitely. After just five days, they started dying.

Walker says they started dying from sleep deprivation. "In fact, sleep is as essential as food because they will die just about as quick from food deprivation as sleep deprivation. So, it's that necessary," he says.

Sleep isn't just for the lazy: it's critical to proper body function. A study restricting sleep to four hours a night had dire effects:

The study's subjects were on the road to diabetes in just six days, and that’s not all - they were also hungry. Van Cauter has made a radical discovery: that lack of sleep may be contributing to the epidemic of obesity in this country through the work of a hormone called leptin that tells your brain when you’re full.

So, we feed our nation full of High Fructose Corn Syrup, have them work at sedentary jobs near a refrigerator, allow them breaks from work only to eat, and we don't give anyone time to exercise or sleep. The researchers feel that adding sleep deprivation to the list of key diabetes risk factors may be in order, and that it may even be a factor in many disorders we currently associate with old age.

Homeschool Case in California

Fri Mar 07, 2008 at 11:17:07 AM PDT

The internet is already abuzz with commentary about a recent case involving a homeschooling family, where a California judge,  Justice H. Walter Croskey, wrote, "Parents do not have a constitutional right to home school their children."

And so people have taken that one line and started lining up on either side of the issue, with homeschooling advocates threatening to take it "all the way to the Supreme Court" and homeschooling foes apparently declaring some sort of victory. The defendant himself declared he believes the ruling stems from hostility against Christians and vowed to appeal to the state Supreme Court.

But when you look at the details of this case in context (which even some media didn't report), it changes the debate entirely:

LA Times

The appellate court ruling stems from a case involving Lynwood parents Phillip and Mary Long, who were repeatedly referred to the Los Angeles County Department of Children and Family Services over various allegations, including claims of physical abuse, involving some of their eight children.

All of the children are currently or had been enrolled in Sunland Christian School, where they would occasionally take tests, but were educated in their home by their mother, Phillip Long said.

A lawyer appointed to represent two of the Long's young children requested that the court require them to physically attend a public or private school where adults could monitor their well-being. A trial court disagreed, but the children's lawyer appealed to the 2nd District Court of Appeal, which has jurisdiction over Los Angeles, Ventura, Santa Barbara and San Luis Obispo counties.

The appellate panel ruled that Sunland officials' occasional monitoring of the Longs' home schooling -- with the children taking some tests at the school -- is insufficient to qualify as being enrolled in a private school. Since Mary Long does not have a teaching credential, the family is violating state laws, the ruling said.

"Parents do not have a constitutional right to home school their children," wrote Justice H. Walter Croskey in a Feb. 28 opinion signed by the two other members of the district court. "Parents who fail to [comply with school enrollment laws] may be subject to a criminal complaint against them, found guilty of an infraction, and subject to imposition of fines or an order to complete a parent education and counseling program."

Pet Food Contamination May Have Killed in 2004

Thu Mar 06, 2008 at 10:20:29 AM PDT

A new study from the Journal of Veterinary Diagnostic Investigation suggests that melamine-tainted pet foods may have been behind a large dieoff of pets in 2004 in asian countries. It was written off as coincidence ("Our popular dog foods are fed to a lot of old, sick animals"), or possible mycotoxin.

Hat tip to the Pet Connection Blog:

The Journal of Veterinary Investigative Diagnosis reported that the Asian cases were initially attributed to contamination with mycotoxin, and that “an estimated 6,000 dogs and a smaller number of cats developed nephrotoxic renal failure in 2004.” But their own research, working with tissue samples from animals from both years discovered characteristic crystals and kidney damage typical of melamine-associated renal failure (MARF) caused by the ingestion of melamine and cyanuric acid:

This study provides compelling evidence that the pet food–associated renal failure outbreaks in 2004 and 2007 share causation. In particular, the outbreaks share identical clinical, histologic, and toxicologic findings. Given the unique nature of the histologic features and the specificity of the toxicologic tests in this study, it is reasonable to conclude that both are examples of MARF. Although the source of melamine and cyanuric acid responsible for the 2007 MARF outbreak has been identified as vegetable protein concentrates imported from China, the source in the 2004 outbreak remains undetermined.

[….]

The addition of melamine, cyanuric acid, or both to enhance apparent protein content of vegetable concentrates is reportedly commonplace in some regions. Because chronic interstitial fibrosis is a self-perpetuating process and a common finding in animals with chronic kidney disease, sublethal MARF could represent an important, previously unrecognized cause of chronic kidney disease in dogs and cats. Interestingly, the contaminated wheat gluten in the 2007 outbreak was a human food–grade product. The potential effects of ingestion of similarly contaminated material by people are unknown.

This makes a lot of sense to me - there was no reason to think the practice was new - but it's also disturbing in how widespread it may have been, and leaves open the idea that a lot of animals have had their health subtly damaged by melamine for a very long time. Not to mention, of course, what's in our own food supply.

Time to get to work in the garden!

Mother of two develops innovative new fuel cell technology

Sun Mar 02, 2008 at 09:02:18 AM PDT

Admittedly, that's not the headline most media have chosen to go with.

(What is this, news for parrots?)

Still, I think it's valuable to remember that one can be a mother and still be other things. (Especially since we have talked often here about how unfriendly academia can be to mothers.)

Sossina HaileSossina Haile, a professor of Materials Science and Chemical Engineering at Caltech, was featured recently in Newsweek as one of the "Who's Next 2008." Her group has been working on fuel cells since the late '90s, and has an idea for solid acid fuel cells. Two of her grad students have created a company, Superprotonic, to commercialize the technology.

A fuel cell is a device for converting chemical energy into electricity - basically a battery that can be refueled (like a combustion engine) rather than only recharged. This is convenient because then you can build electric cars that can be quickly refilled with fuel, as we do now, rather than forcing a battery change-out or a long plug-in recharge. Current fuel cells work, but there are issues. They're expensive, among other reasons because of their use of platinum, and their temperature ranges are inconvenient - either too low, requiring cooling, or too high, requiring special and expensive high heat materials and engineering. Dr. Haile's solution uses Cesium Hydrogen Sulfate, and wants a temperature range right in line with an automobile's operating temperature.

Dr. Haile was a refugee from Ethiopia and attended MIT for her undergraduate and graduate study. She joined the faculty at Caltech in 1996 - I am sure in part because of their efforts to seek female and minority faculty members. I remember the days when there was an attitude when doing such was surely detrimental to the overall output of the Institute. I find it especially pleasing to see a young female professor with children becoming one of the faculty stars.

Strokes among middle-aged women triple

Sat Feb 23, 2008 at 10:10:53 PM PDT

Stroke is uncommon in women, especially in younger women. But there's an alarming study out showing that women are experiencing strokes at an accelerated rate:

Nearly 2 percent of women ages 35 to 54 reported suffering a stroke in the most recent federal health survey, from 1999 to 2004. Only about half a percent did in the previous survey, from 1988 to 1994.

Men in the same survey did not show an increase. The risk factor that appears to be in play is increased obesity.

The increase makes stroke more common in middle aged women than in men, a significant reversal from the previous statistics, where men in this age range had twice the rate of strokes.

The article notes that these women were on medications to control blood pressure and cholesterol, which are supposed to limit the risk of stroke.

While they are showing that women are getting larger around the waist, I'm skeptical. Surely the men are putting on pounds at a similar rate, and yet their risk did not change in this survey. What could be going on?

Travelling Amtrak

Sun Jan 27, 2008 at 09:51:09 AM PDT

"Everyone's a rail fan. Some people are just quieter about it than others."

Nevada streamThat's what a gentleman said to me when I asked him if he was a railfan. Diehards are easily recognized by their casual identification of a location that is to the casual observer, nowhere.

But I loved the truth in it. Trains are special. A road trip, the classic American vacation is fine, but the train version is far better. A dining car, the chance to walk around, no sleepy drivers, easy bathroom access - all of the inconveniences of car travel are gone. Even a familiar path is different from the tracks.

He works for Burlington Northern, and he grew up in Wyoming. So, he comes by his knowledge from more than mere fandom. He tells me that the switch we've just passed is the path to Cheyenne.  We talk about Amtrak, and the perennial battle to keep it alive in Congress. The track we're on used to be on a regular route between Denver and Seattle, but it was dropped despite ample ridership because somebody in Washington had to make a budget cut. He tells me about the towns in Wyoming that used to rely on the train in winter, that are unaccessible by road when the train can still get through. Not many people can tough it out.

Amtrak doesn't suffer from lack of ridership. What vexes it is an upfront, obvious subsidy that has to be explicitly renewed each year. Highway funding does not require reauthorization, and the need for highways is obvious even to the dullest Congressman. Airlines are barely profitable even though they don't pay for their own airports or runways. Amtrak, forced to get by on crumbs, rents time on the tracks from the freight companies, which run their cargoes first, making Amtrak trains late and slow. The tracks are functional, but they're not the sleek, smooth tracks of Europe that permit bullet speeds. Even at 50 MPH, the train rolls and jerks from side to side as it travels.

Why are we the only industrialized country without a solid passenger rail system again?
