That people in all cultures around the world use plant drugs to heal, intoxicate, or enhance themselves is well known. What is less well known – at least to me – is that many cultures give drugs to their dogs to improve hunting success. A new paper in Journal of Ethnopharmacology by B.D. Bennett and R. Alarcón reviews the plants used in lowland Ecuador, Peru and elsewhere.
They find a wide variety of drugs used. Some are clearly medicinal or just hide the dog’s scent. Others are intended as enhancers of night vision or smell. Some are psychoactive and intended to influence behaviour – make it walk straight, follow game tenaciously, be more alert, understand humans, or “not become a vagrant”. Several drugs are hallucinogenic, which may appear bizarre – how could that possibly help? The authors suggest that in the right dose they might create synaesthesia or other forms of altered perception that actually make the dogs better hunters by changing their sensory gating. Is drugging dogs OK? Continue reading
A recent series of papers have constructed a biochemical pathway that allows yeast to produce opiates. It is not quite a sugar-to-heroin home brew yet, but putting together the pieces looks fairly doable in the very near term. I think I called the news almost exactly five years ago on this blog.
People, including the involved researchers, are concerned and think regulation is needed. It is an interesting case of dual-use biotechnology. While making opiates may be somewhat less frightening than making pathogens, it is still a problematic use of biotechnology: millions of people are addicted, and making it easier for them to get access would worsen the problem. Or would it?
Jonathan Moreno presented a special lecture the 18th about “Mind Wars”, the military applications of neurotechnology. Here are some of my notes and comments inspired by this stimulating lecture. Continue reading
Doctors Offering ‘Gay Gene’ To Same Sex Couples Wanting Gay Children: apparently Dr. William Strider at the Fertility Center of Chicago suggests that homosexual parents should have the option of increasing the chances of their kid being homosexual:
“When straight couples have children, the majority of them want their children to be straight as well. That is why most straight parents have trouble accepting it when their children announce to them that they are gay,” … “So it only makes sense that same-sex couples would want children that carried out their same family values of homosexuality.”
The article is likely reporting wrong on what method would be used: germline manipulation sounds like a unproven and risky approach, while PGD is a proven technique that could presumably select based on X-chromosome sequence. And given the topic it is not implausible that Dr. Strider is being misquoted. But let’s take everything at face value: would it be ethical to select for sexual preference?
Christmas is the season when prices, costs and value are on everybody’s mind. At least when trying to estimate how much a present is worth to a friend or family member (and the value of our own happiness at their happiness): is it really worth the price in the store? Lee Billings recounts a fascinating discussion with the astronomer Greg Laughlin and natural capital expert Taylor Ricketts about How Much Money Would an Earth-Like Exoplanet Really Be Worth to Us? A closely related question is of course: what is Earth worth?
Today, 31 years ago, the human species nearly came to an end. Lieutenant colonel Stanislav Petrov was the officer on duty in bunker Serpukhov-15 near Moscow, monitoring the Soviet Union early warning satellite network. If notification was received that it had detected approaching missiles the official strategy was launch on warning: an immediate counter-attack against the United States. International relations were on a hair trigger: just days before Korean Air Lines Flight 007 had been shot down by Soviet fighter jets, killing everybody onboard (including a US congressman). Kreml was claiming the jet had been on a spy mission, or even deliberately trying to provoke war.
Shortly after midnight the computers reported a single intercontinental missile heading towards Russia.
There could be increased numbers of psychopaths in senior managerial positions, high levels of business: a paper in Journal of Forensic Psychiatry & Psychology has demonstrated that smart psychopaths are hard to detect as psychopaths. The authors tested participants for psychopathic tendencies using a psychological scale, and then tested their arousal levels through galvanic skin response while showing normal or upsetting images. The interesting finding was that only lower IQ participants showed the expected responses (lowered startle when viewing aversive images in psychopaths): smarter participants seemed to be able to control their emotions.
The lead author, Carolyn Bate, said:
“Perhaps businesses do need people who have the same characteristics as psychopaths, such as ruthlessness. But I suspect that some form of screening does need to take place, mainly so businesses are aware of what sort of people they are hiring.”
Should we screen people at hiring for psychopathy?
Cryonics – the practice of freezing people directly after death in the hope that future medicine can resuscitate them – is controversial. However, British Columbia is the only jurisdiction with an explicit anti-cryonics law (banning advertising or sale of cryonics services), and a legal challenge is apparently being put together. The motivations for the law appear murky, but to some this is a rights issue. As Zoltan Istvan notes, “In a world where over 90 percent of the people hold religious views of the afterlife, cryonics could become a noteworthy global civil rights issue. ” Maybe the true deep problem for getting cryonics accepted is that it is a non-religious afterlife, and we tend to give undue privilege to religious strange views rather than secular strange views.
