A Pill A Day Keeps the Racism Away

In an unusual study from Oxford University published in the journal Psychopharmacology, scientists appear to have isolated an unusual side-effect in a common heart disease drug – it minimizes racism.  Volunteers who took the beta-blocker appears, on a standard psychological test, to be less racist than did those who were given the placebo.

Goodbye Racism

The racism the test looked at was racism at an “implicit” level and what the scientists believe they are showing is that much of racism is based on fear and emotional responses.  Beta blockers suppress fear and can also be used to treat anxiety and panic.  Experimental psychologist Dr. Sylvia Terbeck from Oxford University said, “We wanted to study the neurobiology of prejudice. Our results offer new evidence about the processes in the brain that shape implicit racial bias.”

She continued,

“Implicit racial bias can occur even in people with a sincere belief in equality. Given the key role that such implicit attitudes appear to play in discrimination against other ethnic groups, and the widespread use of propranolol for medical purposes, our findings are also of considerable ethical interest.”

During the study, two groups of 18 white participants took a “racial Implicit Association Test” one or two hours after they took either the propranolol or the placebo.

The researchers discovered that it took placebo volunteers longer to associate pictures of black people with positive words than it took to associate white people’s faces with positive words.

Professor Terbeck explained to the Mail Online that,

“We think this test reveals what a person feels. It looks at the automatic emotional attitude. We found those who took the placebo had a negative racial emotional bias.”

Creating Controversy

The results of the study have definitely stirred up controversy. Co-author Professor Julian Savulescu from the Oxford University’s Faculty of Philosophy said that the results raise the “tantalizing possibility that our unconscious racial attitudes could be modulated using drugs, a possibility that requires careful ethical analysis. However, Dr. Chris Chambers, from the University of Cardiff’s School of Psychology, countered that the results need to be viewed with a great deal of caution.

He said,

“We don’t know whether the drug influenced racial attitudes only or whether it altered implicit brain systems more generally. And we can’t rule out the possibility that the effects were due to the drug incidentally reducing heart rate. So although interesting, in my view these preliminary results are a long way from suggesting that propranolol specifically influences racial attitudes.”

DARPA Cheetah Breaks Record

It looks like a futuristic toy that one might see in a movie. But it’s actually real. The Defense Department's Defense Advanced Research Projects Agency (DARPA) has recently developed a robot that can run up to 18 mph.  While 18 mph may not sound like a dazzling amount, it is 5 mph faster than the previous record set in 1989, and it is significantly faster than the average jogger.

The news release on DARPA’s website says,

"The robot's movements are patterned after those of fast-running animals in nature. The robot increases its stride and running speed by flexing and un-flexing its back on each step, much as an actual cheetah does."

The video here shows the “cheetah” robot running on a laboratory treadmill powered by an off-board hydraulic pump and using a boom-like device to keep it running on the treadmill.  DARPA says that it will test a free-running prototype later this year.

Certainly, the DARPA M3 performer for Cheetah could have many military uses for emergency response, firefighting, advanced agriculture and more.  DARPA has not yet revealed the intended use for this prototype.

 

Redheads Immune to Local Anesthetics

The Journal of the American Dental Association recently published new research revealing that redheads are in fact impervious to local anesthetics. This explains why redheads are more wary of doctors and dentists than patients with other hair colors.

The research proposes that the phenomenon is a result of a mutation in the same gene that dictates hair color. The gene leads to melatonin production in people with blond, brown and black hair, but the redhead mutation in the MC1R gene makes a substance called pheomelanin instead. This leads to the red hair and the characteristically fair skin.

This is not the first study to address the issue. In 2004, a project revealed that redheads rProfequire an average of 20% more general anesthesia than other patients. A study in 2005 showed similar results.

The MC1R gene is part of a group of receptors responsible for pain comprehension in the brain. As a result, the mutation amplifies the body’s pain sensitivity. The mutation can sometimes be found in people of other hair colors, though not often. The latest research showed that 65 of 67 redheads had the MC1R gene variant, as opposed to 20 of 77 brunettes.

The study also mapped the participants’ anxiety and fear of the dentist, and found that those with the MC1R mutation were remarkably more wary of the dentist, and more than doubly likely to avoid any sort of dental care.

Dr. Daniel I. Sessler of the study said “The reason we studied redheads in the beginning, it was essentially an urban legend in the anesthesia community saying redheads were difficult to anesthetize. This was so intriguing we went ahead and studied it. Redheads really do require more anesthesia, and by a clinically important amount.”

An erection normally involves the working of many other glands, especially the thyroid purchase cheap levitra frankkrauseautomotive.com gland.

He added, “Because they’re resistant, many redheads have had bad experiences. If they go to the dentist or have a cut sutured, they’ll need more local anesthetic than other people.”

Other recent studies have revealed that although redheads are more sensitive to certain pains and more immune to anesthetics, their skin is tougher than that of other people. In fact, they are less susceptible to skin-related pain.

Professor Lars Arendt-Nielsen explained: “Our tests showed that redheads are less sensitive to this particular type of pain. They react less to pressure close to the injected area, or to a pinprick. They seem to be a bit better protected, and that is a really interesting finding.”

Redheads are also less sensitive to hot and spicy foods, and more sensitive to the cold.

Indiana’s Deadliest Tornadoes

Three days ago, on March 2nd, several tornadoes struck southern Indiana. Washington, Jefferson, Ripley, Clark and Scott counties were affected, and more than 14 people were killed.

These were certainly not the first twisters to hit the region, nor were they the worst. Here is a list of some of the deadliest tornadoes in Indiana history:

 

  • The ‘Tri-State Tornado’ struck in March, 1925, sweeping from southern Missouri to southwestern Indiana at more than 200 miles per hour. More than 730 people were killed across the two states, while more than half of Princeton was wiped out.

  • In April of 1965, Palm Sunday saw ten tornadoes strike Indiana. This disaster was the most deadly in the state’s history, causing more than 137 casualties and 1,700 injuries, as well as over $30 million in property damage. As a result, the state worked to develop more efficient tornado safety plans.

 

  • In 1974, more than twenty tornadoes struck in April, killing at least fifty citizens and injuring more than one thousand, a tragic but significant improvement on earlier crises.

 

  • Sixteen years later, in June of 1990, no less than 37 tornadoes struck Indiana, affecting 31 counties and killing at least ten people in Petersburg and Bedford.

 

  • In November of 2005, more than 22 people were killed by a tornado in Vanderburgh and Warrick counties, also in southwestern Indiana.
