Question of the Day

March 26, 2010

Science often looks to explain the extraordinary, or the myth, by citing the fantastic ecological, epidemiological, and environmental eccentricities. An example, you ask? “Modeling the Hydrodynamic Situation of the Exodus”.

Today, we challenge you to match the tales of Passover to the possible scientific explanation.

1. The burning bush.
2. The parting of the Red Sea.
3. The ten plagues, specifically: frogs.
4. The ten plagues, specifically: death of the first born.
5. The ten plagues, specifically: water to blood.

A. Dinoflaggelates
B. Spontaneous combustion, natural gas, or a volcanic vent
C. Mycotoxins
D. A “wind setdown”
E. Extinction of predators

Hawai’i is often considered an original source for popular tropical fruits like bananas, pineapples, and mangoes. However, this produce was brought in by the Tahitians. Other species were brought in at later dates, including boars, insects, sugar cane, and rats. In order to keep that last from eating all of the profitable sugar cane, a planter imported what species that has since both failed to control the rat population and grown out of control itself?

a) chickens

b) foxes

c) mongoose

d) snakes

e) bears

Answer: C, Mongoose.

The farmers who were responsible for bringing over the mongoose were under the impression that since a caged mongoose will eat a caged rat, a mongoose is a logical predator in the wild. However, given that rats are nocturnal and mongoose are diurnal, this was a largely ineffective measure, and rats are still primarily controlled by fires and traps in sugar cane fields.

Historically, humans haven’t done the best job of considering the long-term implications of their societal structures. Literally, huge structures have been built in earthquake fault zones, volcanic hotspots, and coastlines vulnerable to tsunamis. One city in particular, with an estimated population of over 10 million, is built on the corner of three tectonic plates, and is the only metropolis that spans two continents. Which city is this?

A. Istanbul, Turkey
B. Sao Paulo, Brazil
C. Beijing, China
D. Delhi, India
E. Mexico City, Mexico

ANSWER: A, Istanbul. Because of poorly-enforced architectural codes and limited resources, this is one of the most vulnerable cities to geologic catastrophe. Of course, the question then is: what to do about it? Should existing buildings be retrofitted? Should codes even be enforced, to avert a possible disaster decades in the future, when the economic situation in Turkey is considered?

“Breathe and Speak-Easy,” A Clean Energy Quote Quiz

1. “What the US and China do over the next decade will determine the fate of the world.”

2. “The problem of global warming is primarily a political problem at this point. The science is beyond dispute, but how do we achieve objects that we all know are necessary? That is a political problem.”

3. “Other countries are not pressing the pause button on clean-energy industries, and they will move quickly to capture America’s share of the global market while we sit on the sidelines. The longer we delay, the longer we remain dependent on foreign oil instead of America’s home-grown clean energy resources.”

4. “If you list today’s top 30 companies in solar, wind and advanced batteries, American companies hold only 6 spots. That fact should worry us all.”

5. “At this moment of necessity, we need you. We need some inventiveness. Your country needs you to create new jobs and lead new industries. Your country needs you to mount a historic effort to end, once and for all, our dependence on foreign oil.”
Match the quotes above to the speakers below.”

Last Sunday, February 14, 2010, romantic couples shared food, wine and bonded in many similar ways. Due to the thought-paralyzing effects of what we define as “love,” many laymen, poets, and those afflicted have described this state of emotion as “a sickness.” And psychologists studying certain types of neurotransmitters heartily agree. Which of the following chemicals are produced in the brain when a test subject interacts with, or sees a picture of their object of affection?

A. Dopamine – associated with mood, reward, motivation and voluntary movement
B. Serotonin – associated with appetite suppression, obsessive-compulsive tendencies
C. Oxytocin – creates a bond between two people, increases positive social behaviors
D. Vasopressin – creates a feeling of reward for long-term partnerships
E. Endogenous opioids – “endorphins” that produce a high after emotional bonding

Answer: All of them!
SEA staff, a computer scientist, geologist and biologist, strongly concur with neuroscientists: with these many chemicals being secreted, love most definitely should be categorized as a psychosis!

The USDA recently abandoned a program to track the growth and movement
of cattle in the United States. Approximately how many head of cattle
would this program have monitored?

A. 10 million
B. 35 million
C. 95 million
D. 120 million

Answer: C, 95 million head of cattle. Of that 95 million,
approximately 35 million will go to the butcher where they will yield
over 26 billion pounds of beef. That’s enough beef to make everyone
in the US a quarter-pound burger 6 days a week, 52 weeks a year.

From where will people receive medicine in the case of a bioterrorism attack?

A. Specifically designated pharmacies and grocery stores
B. Centers of Disease Control located in each community
C. The U.S. Postal Service
D. Their refrigerators
E. Specifically designated hospitals and clinics

Answer: C.

In an Executive Order in December 2009, President Obama designated the U.S. Postal Service as the primary responder in the case of a bioterrorism incident in the US. Below is the language of the Executive Order that refers directly to this responsibility.

“Sec. 2. United States Postal Service Delivery of Medical Countermeasures. (a) The U.S. Postal Service has the capacity for rapid residential delivery of medical countermeasures for self administration across all communities in the United States. The Federal Government shall pursue a national U.S. Postal Service medical countermeasures dispensing model to respond to a large-scale biological attack.”

ESTABLISHING FEDERAL CAPABILITY FOR THE TIMELY PROVISION OF
MEDICAL COUNTERMEASURES FOLLOWING A BIOLOGICAL ATTACK
. White House Press Release.

Obama to Announce Bioterrorism Response Plan
“The goal is a national capability for the rapid, reliable and affordable production of an array of medical countermeasures,” Shapiro said. The announcement came hours after the bipartisan Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism gave the federal government an “F” for its preparations to respond to a biological attack that could cause mass casualties.

The commission also issued failing grades to Congress for not reorganizing itself to better oversee anti-terror efforts and to the government generally for failing to recruit and train new national security experts.

Efforts that won an “A” grade: a government review of security at laboratories where scientists work with dangerous pathogens, a new national strategy to improve bioforensic capabilities and the appointment of a White House adviser on weapons of mass destruction.”

Israel has not had a breach in airport security since 2002. Unlike the US’s current strategies, which of the following tactics are employed each day in Israel’s airports to ensure that passengers are safe prior to, and during a flight?

A. All passengers entering the airport must provide an answer to the questions “How are you?” and “Where are you coming from?”
B. Employees who screen baggage can put suspected luggage into a “bomb box” that can contain large explosions.
C. Hidden microphones in each corridor and between seats in waiting areas.
D. A series of threat and vulnerability analyses that are continually updated and improved.
E. Hidden infrared technology can identify irregularities in body temperature, heart rate and respiration.

Correct Answers: A. B. D. E.

Based on several articles, Israeli security crews focus on behavioral signals more closely than the US, which relies mostly on technologies. There was no mention of hidden microphones in the sourced articles below.

It has been said several times on the news while considering the causes of the suffering in Haiti that earthquakes do not kill people. Buildings kill people. Though aphorisitic, perhaps this repeated phrase will serve as a preventative reminder in the future. The Haitian government did not consider the International Code Council Building Codes for safety, nor require similar national standards, and undoubtly, this precaution would have limited the devestation in this country.

Which of the following are not general design strategies that prevent structures from collapsing due to the lateral or horizontal shear loads caused by earthquakes?

A. Engineers ensure that taller buildings are designed to withstand more force than shorter ones.
B. Builders use wood and steel materials for structures on or near fault lines.
C. The joints of a building should be allowed to bend and misshape.
D. The roof should be flexible.
E. A building should maintain rigidity between levels.

Answers: A, D, and E are NOT general design strategies to prevent building destruction during earthquakes.

A. “The taller a structure, the more flexible it is. The more flexible it is, the less energy is required to keep it from toppling or collapsing when the earth’s shaking makes it sway. You can feel this same phenomenon while you’re riding a bus or subway. It requires less effort to remain standing if you flex your body and flow with the bumps and jolts than if you stiffly try to defy them.

Because shorter buildings are stiffer than taller ones, a three-story apartment house is considered more vulnerable to earthquake damage than a 30-story skyscraper. When planning the seismic safety of a building, structural engineers must design the support elements of shorter buildings to withstand greater forces than those of taller buildings.”
- Exploratorium

B. “Ductile materials perform better than brittle ones. Ductile materials include steel and aluminum. Brittle materials include brick, stone and unstrengthened concrete.”
- Buildings in Earthquakes PowerPoint.

C. Flexible joints prevent snapping and breaking, leading to greater instabilities.

D. “In 1984 the magnitude 6.2 Morgan Hill, California, earthquake shook the West Valley College campus, 20 miles away. Instruments in the college gymnasium showed that its roof was so flexible that in a stronger or closer earthquake the building might be severely damaged, threatening the safety of occupants. At that time, these flexible roof designs were permitted by the Uniform Building Code (a set of standards used in many states). Many industrial facilities nationwide were built with such roofs. The center of the gym roof shook sideways three to four times as much as the edges. The Code has since been revised to reduce the flexibility of such large-span roof systems and thereby improve their seismic resistance.”
- USGS Building Safer Structures

E. ” In planning for earthquakes, engineers today have come to value flexibility more than strength. For example, small elements of the infrastructure like gas lines and water mains are often designed with elastic loops so they bend rather than break.
Buildings are more flexible too. Dr. Salvadori compares a faulty building to a dry old tree, strong but liable to break under heavy winds, and a well-engineered one to a reed, lighter, more resilient and less likely to snap.
”A building’s ability to absorb motion is as important as its ability to withstand collapse,” said Robert Silman, a New York structural engineer. Wright’s Foresight.”

What makes the Volt an E-REV rather than a HEV?

A. Its gasoline engine does not power the wheels of the car.
B. Unlike current hybrids, it can be plugged into an electrical outlet.
C. It can only travel 40 miles (64 km) on stored electricity.
D. It stores electric power within a lithium-ion battery pack.
E. Its design predicts a drag coefficient higher than other similar vehicles.

Answer: A. Its gasoline engine does not power the wheels of the car.

B. There are currently several types of plug-in hybrids (PHEVs) being designed and tests. (2010 Prius)
C. This is true, and the distance is relevant: the average American commutes 33 miles each day.
D. The battery will be 6 feet long (1.8 meters) and weigh nearly 400 pounds (181 kg)! But this characteristic does not prevent the Volt from being classified as a hybrid.
E. The Chevrolet Volt boasts a .28 drag coefficient compared to Toyota Prius’ .30. At least, according to GM.

“An E-REV like the Chevrolet Volt is unique from a hybrid or plug-in hybrid in that the vehicle’s wheels are always driven electrically by an electric drive unit.”

“An E-REV like the Chevrolet Volt represents a significant departure from conventional hybrids. In a E-REV, the wheels are turned by an electric drive unit, whereas in conventional hybrids the wheels are turned by an electric motor, a gasoline engine, or both. For short trips, E-REVs will run on battery power alone. For longer trips, additional electricity can be supplied by an internal combustion engine or a fuel cell. The battery and propulsion systems are sized so that when sufficient energy is available from the battery, the engine (or fuel cell) is not required for operation. During this electric only phase of driving, the battery, motor, and power electronics are designed to deliver full performance, acceleration, top speed, hill climbing on electric power alone.”

Evidence has suggested that for 800,000 years prior to the 1800s, the atmosphere varied between 180 ppm and 280 ppm CO2. Currently, many groups, aware of that our atmospheric carbon is at 388 ppm and rising 2 ppm each year, are devising ways to reduce atmospheric CO2.

Which of the following has not yet been discussed as a method of reducing CO2 in the atmosphere? (and is also most likely impossible!)

A. Sequestering CO2 in cement.
B. Liquefying CO2 and pumping it into soil.
C. Reducing the frequency of volcanic eruptions.
D. Producing biochar through the pyrolysis of biomass.
E. Venting CO2 into space.

Answer: C. Reducing the frequency of volcanic eruptions. (Not possible nor helpful!)

A. Cement

http://bit.ly/8d0rGa. August 2008.

B. Soil
Ohio State University. Soil Carbon Sequestration – Fundamentals
http://bit.ly/7ibybz.

C. Reducing or limiting volcanic eruptions has NOT been discussed as a method.

“Carbon dioxide is abundant in volcanic gases, but not enough to significantly contribute to the greenhouse effect. Volcanoes contribute about 110 million tons of carbon dioxide per year while man’s activities contribute about 10 billion tons per year. The problem is complex, for volcanoes can help cool the earth’s surface by forming sulfuric acid aerosols that reflect the sun’s rays, and also contribute to global warming by giving off carbon dioxide into the atmosphere, which contributes to the greenhouse effect.”
http://volcanology.geol.ucsb.edu/gas.htm – University of California, Santa Barbara.

D. Biochar
“Pyrolysis of waste biomass can generate fuels and biochar recalcitrant against decomposition. If biochar is returned to agricultural land it can increase the soil’s carbon content permanently and would establish a carbon sink for atmospheric CO2. In this case the use of crop residues as a potential energy source may improve soil quality and reduce greenhouse gas emissions in a complementary not competing way. ” http://www.biochar.org/joomla/

E. Venting CO2 into space.
“[Alfred] Wong believes it should be possible to artificially coax carbon dioxide molecules into leaving the planet’s atmosphere in larger numbers. He proposes doing this by first ionizing more carbon dioxide molecules (one idea is to zap dust in the sky with lasers to release more electrons) and then guiding the resultant carbon dioxide ions to the appropriate altitude from which they could then drift into space through a series of natural processes.”

According to Dr. Steven Schlozman of Harvard Medical School, we can easily hypothesize the neurological states of Zombies, based on their physical actions. Which of the following anatomical features would not account for the rage, walking and decision-making difficulties, insatiability, and flesh-eating characteristics that Zombies possess.
(We are referring to those infected beings of the Night of the Living Dead, not the faster versions in 28 Days Later.)

A. An ablated anterior ventromedial hypothalamus
B. A shrunken amygdala
C. A damaged anterior cingulate cortex
D. A poorly developed frontal lobe
E. Cerebellar degeneration

Answer: B. A shrunken amygdala.

“[Zombies have] a whole lot of amygdala going on, amygdala, which is the region of the limbic system that’s responsible for very, very base emotions – usually rage, fear and maybe lust.” Dr. Steven Schlozman, co-director of the Medical Student Education in Psychiatry at Harvard Med School.

A. The anterior ventromedial hypothalamus controls satiety. Mice that have had this region surgically removed can eat themselves to death. This type of neurological degeneration could very well be responsible for zombie’s food lust.
C. The anterior cingulate cortex controls, among other functions, rationality and empathy, two under-rated skills in the zombie community.
D. The frontal lobe controls problem solving.
E. The cerebellum is crucial for motor controls.

Earlier this week a federal judge ruled that a lawsuit filed by the American Civil Liberties Union against the US Patent and Trademark Office and a Utah-based research company could move forward. The suit alleges that patents for human genes resrict open research and thereby violate free speech.

When was the first patent issued for a human gene?

Answer: In 1982, the USPTO issued a patent to the Regents of the University of California for work carried out on the construction of a plasmid contained in a bacterium and expression of genes for chorionic somatomammotropin.
