Show Notes

A horse is a horse

• The low down
• The first successfully cloned horse was born in 2003
• Today, there are only a few hundred equine clones, created mainly for breeding
• In 2007 the FEI’s general assembly decided that cloning was "potentially against the spirit of sport in that it was unfair
• Significance
• July 2012 the Féderation Equestre Internationale (FEI) lifted a ban on cloned horses and their progeny competing in the Olympic Games
• The FEI has been careful to emphasize that cloning is a breeding technique only
• A key factor in the decision was the high price of cloning, which has since come down
• The federation determined that the clones were only 98 percent copies of the originals, the 2 percent margin was what ultimately caused the FEI to overturn the ban
• Currently the American Quarter Horse Association won’t allow clones, neither does the Jockey Club, which registers thoroughbreds in North America
• A key factor in the decision was the high price of cloning, which has since come down
• The federation determined that the clones were only 98 percent copies of the originals, the 2 percent margin was what ultimately caused the FEI to overturn the ban
• Currently the American Quarter Horse Association won’t allow clones, neither does the Jockey Club, which registers thoroughbreds in North America
• A top stallion for in vitro fertilization can go for tens of thousands of dollars
• The cloning process can cost more than a hundred thousand U.S. dollars, and there are no guarantees that the clone will match the talent of the original
• The most common use for cloned horses is to perpetuate genetic material, while the original horse can travel and compete
• Most male horses in high-level competitions are geldings and a mare can bear only so many foals
• Of Note
• In the end only 300-odd horses compete in the Olympics, and clones would have to battle their way to the top just as traditionally bred horses do.
• Needless of any cloning ruling it is widely agreed that environment, training, nutrition, and relationship with the rider have an incalculable impact on the horse’s performance

Possible Olympic tech for the future

• Holographic Obstacles
• In Olympic equestrian events 100 riders are injured in eventing falls every year, and when a multi million-dollar horse goes down, even a minor injury like a twisted ankle can end its career
• Line-of-sight infrared beams could monitor the edges of the obstacles; if the horse breaks the beam, the system would instantly alert the judges, and the crowd, to the fault
• Smart Landing Pads
• Scoring the exact length of a long or triple jump can be imprecise and time-consuming when landing in a sand pit
• Researchers at Arizona State University have developed a 2,016-pressure-sensor array to map where an athlete hits the ground
• Underneath the sand in the landing pit, a dozen or so of the mats could record the exact point of touchdown where computer could automatically calculate the length of the jump
• Head-up Goggles
• During events swimmers are not able to see where they stand in the event
• With an integrated head-up display could broadcast a live view of the competition and help racers to better pace themselves
• Automatic Goalkeeper
• German researchers have developed an automated goal-tracking system for american soccer (football)
• Actuators around the net generate a magnetic field across the face of the goal.
• When the ball passes through that field, a chip embedded in the ball sends a signal to the ref’s watch within one tenth of a second.
• Retractable Diving Board
• On a good day, a diver’s head misses the board by a couple of inches
• In the one second a typical diver is airborne above the plane of the board, it could retract as much as three feet

Land speed record

_{YouTube channel : NationalGeographic | Credit: Ken Geiger, National Geographic}

• The low down
• At the Cincinnati Zoo five cheetahs each complete several sprints a day, bolting out of the back of one of the zoo’s vans and chasing fluffy toy dogs as they were pulled across a meadow on a high-speed cord.
• They used to long sprints regularly running for zoo crowds on a USA Track & Field-certified course
• It’s not only good for the individual cats, who get much-needed exercise, but good for the species as well
• The zoo’s track-star cheetahs have helped raise over a million U.S. dollars for conservation
• Significance
• Olympian Usain Bolt’s made a new world record of 9.58 seconds in a standing 100-meter dash
• On June 20, Sarah an 11-year-old cheetah was radar-timed at up to 61 miles (98 kilometers) an hour in a standing 100-meter dash
• The June 20 sprint is the fastest timed 100 meters ever run by anything on the planet
• Of Note
• Even though this record was broken almost certain that cheetahs in the wild—lean, hungry, chasing down antelopes for their own survival or that of their cubs – have run considerably faster.

New species on Flickr

• The low down
• While randomly flipping through images posted on the online database an entomologist spotted a previously unknown species of lacewing
• The new lacewing, which has a 30-millimeter wingspan, were taken in a forested park north of Kuala Lumpur, Malaysia, by an amateur photographer and then posted online
• The entomologist suspected the creature was an undescribed species; however, the the photographer had released the insect after taking its picture
• Researchers had to wait until the shutterbug revisited the area and collected a specimen before they could officially write up their discovery

– SPACECRAFT UPDATE –

Slowly but surely inch by inch Voyager 1 eyes the edge of the Solar System

• Last time on SciByte
• Habitable Planets & Chimps | SciByte 24 – Voyager 1 – Update [December 7, 2011]
• Talking Robots & Voyager 1 | SciByte 51 – Voyager 1 takes one step closer to interstellar space [June 19, 2012]
• The low down
• Researchers are eyeing three key parameters for signs that Voyager 1, which launched in 1977, has escaped into interstellar space
• Two of these three parameters are now changing faster than at any other time in the last seven years
• A single day (July 28), the probe measured a 5-percent jump in the level of high-energy cosmic rays coming from outside our solar system, researchers
• The last 5-percent increase Voyager 1 observed took place over a full week in May
• Three days later, however, both measurements had returned to near their previous levels

Morpheus setback

• The low down
• The Morpheus project is what one former project manager called ““Home Depot engineering”
• They are designed as low-budget projects using off-the-shelf parts to build something very quickly that gets 80 percent of the answer and allows the project to keep moving forward
• These type of projects partner with non-traditional aerospace companies
• Significance
• The Morpheus is designed to deliver about 1,100 pounds (500 kg) of cargo to the moon, burn liquid oxygen and methane fuel
• Designed and built by engineers at NASA’s Johnson Space Center in Houston, the insect-like vehicle, had previously made several flights attached to a crane before the attempted free-flight on August 9, 2012
• The engines, appeared to ignite as planned, lifting the vehicle into the air. But a few seconds later, Morpheus rolled over on its side and plummeted to the ground.
• Of Note
• An investigation is currently underway to determine the cause

SCIENCE CALENDAR

Looking back

• Aug 19, 1887 : 125 years ago : Eclipse by baloon : Mendeleeff observes eclipse | Dmitri Ivanovich Mendeleev (1834–1907) used a balloon to ascend above the cloud cover to an altitude of 11,500 feet (3.5 km) to observe an eclipse in Russia. He made the solo ascent above Klin without any prior experience. While his family was rather concerned, he paid no attention to controlling the balloon until after he had completed his observations, at which time he worked out how to land it. Mendeleev is the Russian chemist known for the ordering of the Periodic Table of the Elements. Yet, he was interested in many fields of science. He studied problems associated with Russia’s natural resources, such as coal, salt, metals, and the petroleum industry. In 1876, he visited the U.S. to observe the Pennsylvania oil fields.
