Canada’s first astronaut?

For four and a half months, Canadian high school students Matthew Ho and Asad Muhammed spent every Saturday working on a project.  No, it wasn’t restoring an old car, it was building a homemade satellite/space vehicle.  Somehow, they not only managed to build their spacecraft, they managed to send a Lego minifigure into space.  It’s a shame it wasn’t one of the official Lego astronauts, but the important thing is Canada has gotten someone into orbit!  It’s a victory for the Canadian space program!

The pair were inspired by other videos of people sending balloons into space, possibly these guys.  The two spent only $400 to build their spacecraft, though the planning was meticulous.  They wanted their Lego man to launch and return to them in Canada to avoid having to cross the border to retrieve him.  The ascent took an hour and five minutes; after the balloon popped, the descent took only 30 minutes.  The homemade spacecraft consisted of a lightweight Styrofoam box carrying three point-and-shoot cameras, a wide-angle video camera, and a cellphone with GPS to track the landing. The balloon was bought online and filled with helium from a party store; two mitten warmers were used to ensure the electronics didn’t get too cold on the trip into space.

Hundred Year Old Predictions For The Future Come True!

Ladies Home Journal

Predicting the future is usually difficult although an American engineer did a pretty good job when he wrote his predictions for the next hundred years way back in 1900. 

John Elfreth Watkins was a civil engineer working for American railroads of the 19th century. In 1900, he contributed an article to the Ladies’ Home Journal, entitled “What May Happen in the Next Hundred Years”. Somehow, Watkins was able to foresee the invention of mobile phones, digital photography, television, and even TV dinners. 

Now, 112 years later, a history editor for the Journal’s sister publication, the Saturday Evening Post, dug out the article to see how Watkins did. The article made 28 predictions. Here are some of the more interesting ones he got right and wrong.

Correct Predictions:

– Digital color photography – Watkins didn’t know how it would happen, but wrote about color pictures being able to move around the world in minutes. “Photographs will be telegraphed from any distance. If there be a battle inChina a hundred years hence, snapshots of its most striking events will be published in the newspaper an hour later…photographs will reproduce all of nature’s colors.”

– Mobile phones – He wrote that wireless telephone circuits will span the world even though it was 15 years prior to the first transcontinental call. “We will be able to telephone toChina quite as readily as we now talk fromNew York toBrooklyn.”

– Pre-made meals – He wrote people would purchase ready-to-eat meals from establishments similar to bakeries. “They (the store) will purchase materials in tremendous wholesale quantities and sell the cooked foods at a price much lower than the cost of individual cooking.” He also said these meals would be made in laboratories as opposed to kitchens.

– Television – He foresaw cameras and screens connected by electric circuits that allow people to see events on the other side of the world. “Persons and things of all kinds will be brought within focus of cameras connected electrically with screens at opposite ends of circuits, thousands of miles at span.

– Central heating and air conditioning
 – The great minds he spoke with talked about how a device would regulate the temperature in a house.

The article also correctly predicted “huge forts on wheels”, what we know as tanks, that the population growth will slow, people would get taller and high-speed trains would exist.

What He Got Wrong:

– Free university – “A university education will be free to every man and woman.” While more people are able to attend university, the costs continue to rise forcing many to take on huge debt.

– Fitness levels – “Everybody will walk ten miles…A man or woman unable to walk ten miles at a stretch will be regarded as a weakling.” Watkins wrote exercise would be compulsory in schools, but while it is mandatory to a certain age, obesity levels continue to rise in theU.S. andCanada.

– Mosquitoes terminated – “Mosquitoes, house-flies and roaches will have been practically exterminated.” He thought this would happen because all the breeding grounds, including stagnant pools and swamp lands would be gone.

– Fewer letters – “There will be no C, X, or Q in our every-day alphabet.” He thought those letters would eventually become unnecessary and spelling by sound would be adopted.

It’s downright impressive how many of these predictions have actually come to pass in the 112 years since the column was written. It almost makes you wonder if the days of C, X, and Q being part of the English alphabet are numbered. 

Scientists Discover We’ve Got a Sixth Taste Bud!

Remember back when life was simple and we only had FOUR types of taste buds . . . sweet, sour, salt, and bitter?  And then in the ’80s, we found out there was a fifth type, one that tasted savory flavors?

Well now it turns out we’ve had a SIXTH one all along.  And the flavor it detects will NOT shock you.  Scientists at Washington University in St. Louis have found we have a sixth taste bud . . . that tastes FAT.

The sensitivity of the fat taste bud varies a lot from person to person . . . and could actually be one of the contributing factors to why some people are prone to eat less healthily than other people. More studies on that are coming. Read more on Medical Daily.com

Biggest Scientific Breakthroughs of 2011

From law-violating subatomic particles to entirely new, earth-like worlds, 2011 was an incredible year for scientific discovery. In the past 12 months, scientific breakthroughs in fields ranging from archaeology to structural biochemistry have allowed humanity to rewrite history, and enabled us to open to brand new chapters in our development as a species.

Here are some of our favorites.

 

 

The world’s lowest density material

With a density of less than one milligram per cubic centimeter (that’s about 1000 times less dense than water), this surprisingly squishy material is so light-weight, it can rest on the seed heads of a dandelion, and is lighter than even the lowest-density aerogels. The secret — to both its negligible weight and its resiliency — is the material’s lattice-like structural organization, one that the researchers who created it liken to that of the Eiffel Tower.

 

“Feeling” objects with a brain implant

It could be the first step towards truly immersive virtual reality, one where you can actually feel the computer-generated world around you. An international team of neuroengineers has developed a brain-machine interface that’s bi-directional — that means you could soon use a brain implant not only to control a virtual hand, but to receive feedback that tricks your brain into “feeling” the texture of a virtual object.

Already demonstrated successfully in primates, the interface could soon allow humans to use next-generation prosthetic limbs (or even robotic exoskeletons) to actually feel objects in the real world.

 

Astronomers get their first good look at giant asteroid Vesta

In July of 2011, NASA’s Dawn spacecraft entered the orbit of Vesta — the second largest body in our solar system’s main asteroid belt. Just a few days later, Dawn spiraled down into orbit. Upon reaching an altitude of approximately 1700 miles, the spacecraft began snapping pictures of the protoplanet’s surface, revealing geophysical oddities like the triplet of craters on Vesta’s northern hemisphere — nicknamed “Snowman” — featured here. Dawn recently maneuvered into its closest orbit (at an altitude averaging just 130 miles). It will continue orbiting Vesta until July of 2012, when it will set a course for Ceres, the largest of the main belt asteroids.

NASA’s Kepler Mission changes how we see ourselves in the Universe

2011 was a fantastic year for NASA’s Kepler Mission, which is charged with discovering Earth-like planets in the so-called “habitable zone” of stars in the Milky Way. Kepler scientists announced the discovery of the first circumbinary planet (i.e. a planet with two suns, just like Tatooine); located the first two known Earth-sized exoplanets; quadrupled the number of worlds known to exist beyond our solar system; and spied Kepler-22b — the most Earth-like planet we’ve encountered yet. And here’s the really exciting bit: Kepler is just getting warmed up.

 

Heartbeat-powered nanogenerators could soon replace batteries

In a few years, you may never have to recharge your phone again — provided part of you keeps moving. Back in March, scientists announced the world’s first viable “nanogenerator” — a tiny computer chip that gets its power from body movements like snapping fingers or – eventually – your heartbeat.

The researchers can already use the technology to power a liquid crystal display and an LED, and claim that their technology could replace batteries for small devices like MP3 players and mobile phones within a few years.

Google Doodle Celebrates The Father of Geology, Nicolas Steno!

 

A new Google Doodle today honors the 374th birthday of the Danish anatomist Nicolas Steno, the man widely regarded as the father of modern geology.

The new inanimate Doodle features the Google logo with letters sketched out of three to five layers of earth, depending on the height of the letter and links to search results on Steno.

It is a fitting tribute for the man whose life’s work on rock layers and fossils largely led to the study of geology as we know it today. Intrigued by a shark’s tooth fossil embedded in rock, he set out to learn how one solid object could be found inside another solid object, such as a rock.

He determined that fossils formed when particles in water drifted down and formed layers over objects. Steno hypothesized that the layers of rock are arranged in a time sequence, with the oldest layers on the bottom and the newest on top. His theory became known as Steno’s law of superposition.

Born Neils Stensen in Copenhagen, he was also known as Nicholas Stenonis or Nicholas Steno. He left him home in 1660 to study medicine in Italy, where he became involved with a body of researchers following Galileo’s mathematical approach to science.

Following his geological discoveries, Steno left science, became a devout Catholic, and ministered in Germany, Denmark and Norway. Pope John Paul II beatified Steno in 1988, bringing him one step closer to sainthood.

Google has honored many notable mathematicians and scientists with their patented Doodles, including:

Wasps Can Memorize Faces!

Wasps have amazing ability to memorize and later recall the figures of other wasps, from native cluster. Findings add to other remarkable capacity of these social insects, providing new information on the specializations from the animal world.

 

Wasps are downright phenomenal when it comes to intelligence. They manage to learn, and recognize the figures of other wasps, very quickly. And not only the ability to recognize different physiognomies, but also make the difference between wasps and other insects only after facial analysis.
Studies have shown that wasps recognize different physiognomies, but are also able to remember for a
time of about one week. As these insects live in communities with multiple queens and must follow a strict hierarchy, entomology theories claim that wasps have evolved in this direction to avoid intra-specific conflicts.

Memorizing faces has a very important role in establishing and maintaining social interactions, thus serving survival of social animal species.

New Elements Fl & Lv Headed For The Periodic Table!

Earlier in the year, there were a great deal of new elements discovered by a team of Russian physicists and American chemists.  Of those elements, 113, 115, 117, and 118 are still needing names; elements 114 and 116 are going to be called Flerovium and Livermorium, according to the teams that discovered them.  It’s up to the International Union of Pure and Applied Chemistry, or IUPAC, to approve of said names.

The new elements have names that honor the history of the two teams that worked on discovering them, Russia’s Joint Institute for Nuclear Research and California’s Lawrence Livermore National Laboratory.  Livermorium is obviously named for Lawrence Livermore and Livermore National Laboratory; Flerovium is named for Georgiy Flerov, the founder of Flerov Laboratory of Nuclear Reactions, where the reactions were synthesized.

“Proposing these names for the elements honors not only the individual contributions of scientists from these laboratories to the fields of nuclear science, heavy element research, and super-heavy element research, but also the phenomenal cooperation and collaboration that has occurred between scientists at these two locations,” said Bill Goldstein, associate director of the Physical and Life Sciences Directorate at Livermore.

Farmer Finds Rare Meteorite!

It wasn’t a goose that laid a golden egg for one Missouri farmer — it was an asteroid. Scientists are analyzing an extremely rare meteorite found by a farmer in a tiny Missouri town called Conception Junction (population 202)

It wasn’t a goose that laid a golden egg for one Missouri farmer — it was an asteroid.

Scientists are analyzing an extremely rare meteorite found by a farmer in a tiny Missouri town called Conception Junction (population 202), reports Washington University in St. Louis, which helped identify the rock.

An unnamed farmer had found the unusually heavy stone buried in the side of hill. He sawed off the end of the stone and realized he had something that didn’t come from Earth.

 

The metal rock is studded on the inside with green olivine crystals. It is one of only 20 so-called pallasite meteorites that have been found in the United States.

These types of meteorites are believed to be fragments of large asteroids that had enough internal heat to begin melting, which allowed heavy metals to sink and form a core, while lighter elements became part of the rocky surface.

Pallasites are believed to come from the area where an asteroid’s metal core transitions to olivine in its lower mantle.

Scientists believe the Conception Junction meteorite was once part of an asteroid that flew in the main asteroid belt between Mars and Jupiter until it was nudged toward the inner solar system by Jupiter’s gravity field. Sliced and polished, the stone, which is now in the hands of private collectors, is worth about $200 a gram.

Huge Asteroid Headed For Close Encounter With Earth

A huge asteroid will pass closer to Earth than the moon Tuesday, giving scientists a rare chance for study without having to go through the time and expense of launching a probe, officials said.

Earth’s close encounter with Asteroid 2005 YU 55 will occur at 6:28 p.m. EST Tuesday, as the space rock sails about 201,000 miles from the planet.

“It is the first time since 1976 that an object of this size has passed this closely to the Earth. It gives us a great — and rare — chance to study a near-Earth object like this,” astronomer Scott Fisher, a program director with the National Science Foundation, said Thursday during a Web chat with reporters.

The orbit and position of the asteroid, which is about 1,312 feet in diameter, is well known, added senior research scientist Don Yeomans, with NASA’s Jet Propulsion Laboratory in Pasadena, California.

“There is no chance that this object will collide with the Earth or moon,” Yeomans said.

Thousands of amateur and professional astronomers are expected to track YU 55’s approach, which will be visible from the planet’s northern hemisphere. It will be too dim to be seen with the naked eye, however, and it will be moving too fast for viewing by the Hubble Space Telescope.

“The best time to observe it would be in the early evening on November 8 from the East Coast of the United States,” Yeomans said. “It is going to be very faint, even at its closest approach. You will need a decent-sized telescope to be able to actually see the object as it flies by.”

Scientists suspect YU 55 has been visiting Earth for thousands of years, but because gravitational tugs from the planets occasionally tweak its path, they cannot tell for sure how long the asteroid has been in its present orbit.

Track the asteroid, YU55, and track it’s journey as it passes by Earth on the NASA Asteroid & Comet Watch!
