“Insomniacs can take heart from a new drug that makes the brain enter a state similar to narcolepsy.” In narcolepsy, people suddenly fall asleep, probably because neurons that normally release orexins, proteins that promote the waking state, are defective. Swiss researchers have developed an orexin-receptor blocking drug which, in preliminary tests, promotes sleepiness in laboratory animals and human subjects. As opposed to current sedative-hypnotic drugs, this sleep would be more physiological, i.e. natural: “Unlike other sleeping pills, the drug also increases the time spent in REM sleep, when the brain is thought to organise memories, so it may not cause the forgetfulness and memory disruption linked to regular sleeping pill use.” (New Scientist)

Mysterious Wis. Wonder Spot soon to go
Owner Bill Carney has sold the iconic attraction to the village of Lake Delton for $300,000. The village wants to build a road through the crevice where the Wonder Spot has stood since the 1950s.
Now, the Wonder Spot, one of more than a dozen sites around the nation dubbed ‘gravity vortexes’ and a throwback to postwar, family-oriented tourist attractions, has a date with a bulldozer.” (Yahoo! News)
My family and I never tire of these, having visited a number of such sites (Roadside America ) in the US (as well as abroad). I always detour if one is within reach of our road trip route. (By the way, I subscribe to the theory that these are not-very-mysterious optical illusions.)
U.S. Set to Begin a Vast Expansion of DNA Sampling
…Peter Neufeld, a lawyer who is a co-director of the Innocence Project, which has exonerated dozens of prison inmates using DNA evidence, said the government was overreaching by seeking to apply DNA sampling as universally as fingerprinting.
“Whereas fingerprints merely identify the person who left them,” Mr. Neufeld said, “DNA profiles have the potential to reveal our physical diseases and mental disorders. It becomes intrusive when the government begins to mine our most intimate matters.”
…Immigration lawyers noted that most immigration violations, including those committed when people enter the country illegally, are civil, not criminal, offenses. They warned that the new law would make it difficult for immigrants to remove their DNA profiles from the federal database, even if they were never found to have committed any serious violation or crime.

Scientists offered cash to dispute climate study
Letters sent by the American Enterprise Institute (AEI), an ExxonMobil-funded thinktank with close links to the Bush administration, offered the payments for articles that emphasise the shortcomings of a report from the UN’s Intergovernmental Panel on Climate Change (IPCC).” (Guardian.UK)
Furious Seasons: Caveat Emptor
A weblog about mental healthcare from an investigative journalist who has been a mental health consumer.
What I am is a long-time psych patient who has become quite skeptical about where we are with mental health in this country…. [and] an actual journalist, for what that might be worth in the blogosphere. I am also mentally-ill, having been diagnosed with bipolar disorder (more commonly called manic-depression back then) in 1989. I have been an attentive eyewitness to the psychopharmacological revolution that has swept this nation since about 1990. I have seen and experienced the good. I have seen and experienced the bad. I have lived the in-between.”

Maternal Blood Test Diagnoses Down’s Syndrome
The new test yielded a false positive rate under 2% for trisomy 21 with a detection rate of 66%, said Ravinder Dhallan, M.D., of Ravgen Inc., here, and colleagues. Their company-sponsored, preliminary study of 60 pregnant women was published online in the Feb. 3 issue of The Lancet.” (MedPage Today)
The test is not yet commercially available, and take note that the detection rate is only around 2/3 although there is a negligible false positive rate. But it is far safer than amniocentesis as a first screen.

Stroke of Insight
As a brain expert, Dr. Bolte Taylor was able to analyze the physical and mental effects of her stroke — as it occurred, and as she recovered from the life-changing event.”
And:
Through a Glass, Darkly
If the term “fundamentalism” endures, the classic means of explaining it away—class envy, sexual anxiety—do not. We cannot, like H. L. Mencken, writing from the Scopes “monkey” trial of 1925, dismiss the Christian right as a carnival of backward buffoons jealous of modernity’s privileges. We cannot, like the Washington Post, in 1993, explain away the movement as “largely poor, uneducated and easy to command.” We cannot, like the writer Theodor Adorno, a refugee from Nazi Germany who sat squinting in the white light of L.A., unhappily scribbling notes about angry radio preachers, attribute radical religion—nascent fascism?—to Freudian yearning for a father figure.
The old theories have failed. The new Christ, fifty years ago no more than a corollary to American power, twenty-five years ago at its vanguard, is now at the very center. His followers are not anxiously awaiting his return at the Rapture; he’s here right now. They’re not envious of the middle class; they are the middle class. They’re not looking for a hero to lead them; they’re building biblical households, every man endowed with “headship” over his own family. They don’t silence sex; they promise sacred sex to those who couple properly—orgasms more intense for young Christians who wait than those experienced by secular lovers.” (Harper’s)

How many legislators does it take to change a lightbulb?

California may ban conventional lightbulbs by 2012: “A California lawmaker wants to make his state the first to ban incandescent lightbulbs as part of California’s groundbreaking initiatives to reduce energy use and greenhouse gases blamed for global warming…
‘Incandescent lightbulbs were first developed almost 125 years ago, and since that time they have undergone no major modifications,’ California Assemblyman Lloyd Levine said on Tuesday. ‘Meanwhile, they remain incredibly inefficient, converting only about 5 percent of the energy they receive into light.’ Levine is expected to introduce the legislation this week, his office said. If passed, it would be another pioneering environmental effort in California, the most populous U.S. state. It became the first state to mandate cuts in greenhouse gas emissions, targeting a 25 percent reduction in emissions by 2020. Compact fluorescent lightbulbs (CFLs) use about 25 percent of the energy of conventional lightbulbs.” (Yahoo! News) |
