EFSA identifies insecticides as risk factor for bee colony collapse

Bayer CropScience has defended the use of neonicotinoid insecticides following a report from the European Food Safety Authority (EFSA) identifying three such substances as potentially risky to bees.

EFSA's report highlighted three neonicotinoid insecticides - clothianidin, imidacloprid and thiamethoxam - saying that they should only be used 'on crops not attractive to honey bees'. The investigation into insecticides is part of broader research into potential causes of colony collapse disorder, the rapid loss of adult bees from a colony or hive.

Brazil farmers say GMO corn no longer resistant to pests

Genetically modified corn seeds are no longer protecting Brazilian farmers from voracious tropical bugs, increasing costs as producers turn to pesticides, a farm group said on Monday.

Producers want four major manufacturers of so-called BT corn seeds to reimburse them for the cost of spraying up to three coats of pesticides this year, said Ricardo Tomczyk, president of Aprosoja farm lobby in Mato Grosso state. "The caterpillars should die if they eat the corn, but since they didn't die this year producers had to spend on average 120 reais ($54) per hectare ... at a time that corn prices are terrible," he said.

UK spy agency asks hackers to crack code

Can you crack the code? That's the question Britain's electronic listening agency, GCHQ, is asking in an online campaign to find the next generation of cyber specialists.

GCHQ quietly launched a cryptic website last month featuring a box of code made up of numbers and letters. There is no branding on the site, only the phrase "Can you crack it?" and a box to type in an answer. The agency has now revealed it is behind the campaign, and said Friday it's trying to reach individuals with "a keen interest in code breaking and ethical hacking" for careers at GCHQ. "It's to arouse interest in people who perhaps might not be caught by our normal recruitment campaigns," a GCHQ spokesman said, speaking on customary condition of anonymity.

Fattening Our Kids on GMO Foods

As if there were not already enough concern about the impact of GMO crops on agriculture and the environment, a new international study raises the worry that a diet including genetically modified ingredients may be contributing to obesity.

The effect of GM foods on rats, mice, pig and salmon is being studied by an international team from Hungary, Austria, Ireland, Turkey, Australia and Norway. In March they reported preliminary findings that found no negative metabolic changes in the pigs, salmon or mice they tested. The results released in July link GM corn with modest weight gain in rats. The animals were fed corn with an insect-resistant gene. The control group ate unmodified corn. During the course of the 90-day study, the gm-fed rats gained more weight than the others.

The Shaky Science Behind Obama's Universal Pre-K

"Study after study shows that the earlier a child begins learning, the better he or she does down the road," said U.S. President Barack Obama in Feb. 14 speech in Decatur, Georgia.

Obama wants to help our nation's children flourish. So do I. So does everyone who is aware of the large number of children who are not flourishing. There are just two problems with his solution: The evidence used to support the positive long-term effects of early childhood education is tenuous, even for the most intensive interventions. And for the kind of intervention that can be implemented on a national scale, the evidence is zero.

New Studies Link Cell Phone Radiation with Cancer

Researchers call for greater caution, but skeptics say the evidence from rat studies is not convincing

Does cell phone radiation cause cancer? New studies show a correlation in lab rats, but the evidence may not resolve ongoing debates over causality or whether any effects arise in people. The ionizing radiation given off by sources such as x-ray machines and the sun boosts cancer risk by shredding molecules in the body. But the non-ionizing radio-frequency (RF) radiation that cell phones and other wireless devices emit has just one known biological effect: an ability to heat tissue by exciting its molecules.

Babies with big heads smarter by age eight

According to researchers in the UK, how much a child's head grows by the time he or she reaches age one may be an indication of a child's intelligence.

The researchers from the University of Southampton, in England say although they do not know exactly what causes some babies to have bigger brains than others, the brain volume a child achieves by the age of one year helps determine later intelligence.

How Misguided Feminism Is Harming Our Young Men

A look at the sex breakdown of the CDC's suicide statistics reveals that for males aged ten to fourteen, the suicide rate increased 71 percent between 1979 and 1988; for girls the increase was 27 percent.

Is Universal Preschool Beneficial? An Assessment of RAND Corporation's Analysis and Proposals for California

Reason Foundation [pdf]

by Christopher F. Cardiff and Edward Stringham

May 30, 2006

Almost two-thirds of California families currently choose to send their 4-year-olds to preschool.Of those who do, almost half choose a preschool program operated by the state of California, while the other half choose a privately operated preschool.

If Proposition 82, an initiative on the June ballot, is implemented those figures will radically change. Most family- and other privately owned preschools will vanish, replaced by government-run, taxpayer-funded preschools. This report assesses RAND Corporation's cost benefit analysis and finds that it significantly overestimates the upsides and drastically underestimates the downsides of universal preschool and the California proposal. Using RAND's own data and alternative assumptions based on the studies they reference, it is easy to demonstrate that universal preschool generates losses of 25 to 30 cents for every dollar spent.
