Show Notes:

Fighting Color Blindness with Glasses

  • The low down
  • A pair of researchers from 2AI Labs have developed a wearable eyeglass device that effectively cures red-green color blindness
  • Most mammals have two dimensions of color, a yellow-blue dimension, and a grayscale (or brightness) dimension
  • Some of us have an extra dimension of color vision: The red-green dimension
  • The researchers created a filter technology that further amplified the eyes\’ ability to see blood under the skin, essentially removing \”visual noise\” from the blood signal
  • The Technology
  • The technology works by leveraging our capacity to see the amount of oxygen in another person\’s blood by simply looking at the hue of their skin
  • This eventually led to the development of eyeglasses that enable wearers to perceive emotions and social cues more clearly
  • As they tested the filters they received surprising feedback from users who were colorblind claiming that one of our technologies blew them away in its ability to \’cure\’ their color blindness
  • Of Note
  • The Oxy-Iso filter isolates and amplifies this signal so that it\’s also exaggerated
  • One important thing to note is that Oxy-Iso since can only work on red-green colorblind people who have some of each of their M and L cones
  • However while it does work at helping color-blind persons see red-green differences it also simultaneously handicaps them in their existing yellow-blue perception
  • Medical Applications
  • The devices can be used in the form of eyewear, or in the form of filters in front of illuminants, bathing the room in the blood-amplifying light
  • Outside of the application to color blindness, the two \”Iso\” filters — Oxy-Iso and Hemo-Iso — are principally intended for medical applications
  • The team is moving to put the technology into prescription eyewear, as well as into sunwear, and into general-purpose lighting,\”
  • They are also considering its application in cosmetic lighting
  • Oxy-Amp does is make the vasculature below the skin more salient, and that\’s just to say that skin appears more transparent — more youthful

Dinosaurs Might Have Been Taken out with a One-Two punch

  • Binary Asteroids
  • Space scientists estimate that as many as 15 percent of observable asteroids are binaries
  • This observation has caused scientists problems due to the fact that the evidence of binaries striking the Earth is as few as 2 to 4 percent
  • Meteor Craters on Earth
  • A research team now suggests that many of the craters on Earth thought to have been caused by a single asteroid, may in fact have been caused by binaries
  • A binary could cause just one crater if the two asteroids were close enough together when they struck.
  • Computer simulations showing that binary asteroids hitting the Earth that some of the craters were oblong, or irregularly shaped
  • There are some real craters here on Earth where the crater has some asymmetries that could be explained by a binary strike
  • Chicxulub
  • The Chicxulub crater, off the coast of Mexico, is thought by many scientists to be evidence of an asteroid strike that led to the extinction of the dinosaurs.
  • A team of researchers from the U.K. and Australia has published a paper suggesting that the crater Chicxulub may have come about due to the impact of binary asteroids
  • If that were the case, it likely that the combined size of the asteroid would have been roughly the same as the calculated size of a single entity
  • Since the crater left behind has a diameter of approximately 112 mi [180 km] they would have a combined diameter of ~4-6 mi [7-10 km]
  • The researchers say, that twin asteroids could have been as far apart as 50 mi [80 km] and still produced a single crater.
  • Re-examination
  • Scientists are now looking at other existing craters on Earth to try to determine if they too are possibly the result of binary strikes and if so, recalculate the percentage of binary strikes

Digitizing Pen and Paper

  • When used on special paper, the pens record your every scribble with a built-in camera and can also record audio at the same time and sync that audio with what you write
  • Writing to the Cloud
  • The new pens differ in that they, and the notes they record, are no longer tethered to an individual computer
  • If you are near a hotspot, the Sky pens will begin syncing their notes to Evernote, a Internet-based note taking and storage service, as soon as they stop recording them
  • What it Does
  • Sky pen owners can send up to 500 megabytes of data for free from their smartpens, which is roughly about 70 hours worth of recordings or 10,000 pages of notes
  • Build into the technology is the fact that a a Livescribe player that allows users to see and hear their notes at the same time
  • Evernote arranges the notes by page in their notebook, but when you click or tap on the page, the Livescribe player will collect and display all the pages of notes from that particular recording.
  • The service also scans them for recognizable characters and words so users can search them
  • Drawbacks
  • It can only be used with Evernote and it can be slow to transfer recordings
  • The pen does require company approved paper, although you can print out paper with the proper patterns on it

Altering amyloid protein in Alzheimer\’s

  • A recent study shows that the natural chemicals found in green tea and red wine may disrupt a key step of the Alzheimer\’s disease pathway
  • Amyloid Protein Clumps
  • Alzheimer\’s disease is characterised by a distinct buildup of amyloid protein in the brain that clumps together to form toxic, sticky balls of varying shapes
  • These amyloid balls latch on to the surface of nerve cells in the brain by attaching to proteins on the cell surface called prions
  • New Research
  • This research was looking at whether the precise shape of the amyloid balls is essential for them to attach to the prion receptors
  • If it is then scientists could prevent the amyloid balls binding to prion by altering their shape, as this would stop the cells from dying
  • Recent research has shown that the extracts of red wine and green tea can re-shape amyloid proteins, such that they can no longer harm nerve cells
  • The research team formed amyloid balls in a test tube and added them to human and animal brain cells
  • When they added the extracts from red wine and green tea, which recent research has shown to re-shape amyloid proteins
  • The amyloid balls no longer harmed the nerve cells because their shape was distorted, so they could no longer bind to prion and disrupt cell function
  • What This Means for the Future
  • This research has showed, for the first time, that when amyloid balls stick to prion, it triggers the production of even more amyloid
  • The researchers are now trying to understand exactly how the amyloid-prion interaction kills off neurons

Metric vs. Standard

  • Jason aka Tubsta
  • Shouldn’t you use metric measurements on a science show?
  • The answer
  • They are nearly always in the show notes.
  • Should probably include them in the show more often …
  • A majority of the audience is from the US, where metric measurements are not tangible
  • Although outside of the US standard measurements are probably not too tangible
  • I haven’t doubled up on the measurements in the past due to it taking it a bit longer, In the future I will make an effort to state both standard and metric more often
  • Hopefully combining the two might help people better understand both

  • Feb 15, 1951 : 62 years ago : Nuclear medical therapy : The first atomic reactor to be used in medical therapy treated its first patient at the Brookhaven National Laboratory, Upton, NY. The Brookhaven Graphite Research Reactor (BGRR) began the experimental treatment of brain cancer using neutrons from the reactor. In the following two years, ten patients were treated with boron neutron capture therapy (BNCT). The BGRR also supplied radioisotopes for use by other research organizations, including medical uses, among others. The reactor, the world\’s first dedicated to peaceful exploration of atomic energy operated 1950-68, and was used for research other than medical uses. It was followed by the Brookfield Medical Research Reactor, which reached critically 15 Mar 1959

Neil Armstrong



YouTube Channel NASAexplorer

  • For the famed astronaut’s funeral set on Friday, August 31, flags will be flown at half-staff as ordered by President Obama as “a mark of respect for the memory of Neil Armstrong”.
  • Before NASA
  • He was licensed to fly at 16, before he got his driver’s license
  • Armstrong was active in the Boy Scouts and he eventually earned the rank of Eagle Scout
  • Recognized with the Distinguished Eagle Scout Award and Silver Buffalo Award
  • July 18, 1969, while flying towards the Moon inside the Columbia, he greeted the Scouts: “I’d like to say hello to all my fellow Scouts and Scouters at Farragut State Park in Idaho having a National Jamboree there this week; and Apollo 11 would like to send them best wishes”. Houston replied: "Thank you, Apollo 11. I’m sure that, if they didn’t hear that, they’ll get the word through the news. Certainly appreciate that
  • NASA
  • He became a test pilot with what evolved into NASA, flying more than 200 kinds of aircraft from gliders to jets.
  • Gemini 8
  • Armstrong and pilot David Scott achieved the first docking of two spacecraft in orbit, linking up with an unmanned Agena target vehicle
  • The mission was a near disaster, suffering the first critical in-space failure of a U.S. spacecraft after a stuck thruster set the Gemini spacecraft spinning
  • Armstrong ultimately regained control by using their re-entry system thrusters, steadying the spacecraft and forcing an early, but safe end to the mission
  • Apollo 11
  • Armstrong privately concluded that they had a 90 percent chance of returning safely to Earth but only a 50–50 chance of pulling off a successful landing.
  • It was crucial to land without any sideways motion, lest they risk tipping over at touchdown but the blast of the descent rocket was kicking up moon dust
  • Armstrong fixed his gaze on rocks sticking up through the blowing dust; using them as reference points and guided Eagle slowly downward, about as fast as an elevator
  • In those first few moments on the moon, Armstrong stopped in what he called “a tender moment” and left a patch to commemorate NASA astronauts and Soviet cosmonauts who had died in action.
  • An estimated 600 million people [a fifth of the world’s population] watched and listened to the moon landing, the largest audience for any single event in history.
  • In Wapakoneta, media and souvenir frenzy was swirling around the home of Armstrong’s parents where people were pulling grass out of their front yard.
  • After Apollo 11
  • Soon after returning from the moon, Armstrong announced he would not fly in space again.
  • Armstrong, Aldrin and Collins were given ticker tape parades in New York, Chicago and Los Angeles and later made a 22-nation world tour. A homecoming in Wapakoneta drew 50,000 people to the city of 9,000.
  • In 1970, Armstrong was appointed deputy associate administrator for aeronautics at NASA but left the following year to teach aerospace engineering at the University of Cincinnati.
  • Words of remembrance
  • Buzz Aldrin, Apollo 11 lunar module pilot and second man to walk on the moon | “Whenever I look at the moon it reminds me of the moment over four decades ago when I realized that even though we were farther away from Earth than two humans had ever been, we were not alone.”
  • Apollo 11 command module pilot Michael Collins | “He was the best, and I will miss him terribly,”
  • NASA Administrator Charles Bolden | “As long as there are history books, Neil Armstrong will be included in them, remembered for taking humankind’s first small step on a world beyond our own.”
  • NASA Administrator Charles Bolden | “As long as there are history books, Neil Armstrong will be included in them, remembered for taking humankind’s first small step on a world beyond our own. Besides being one of America’s greatest explorers, Neil carried himself with a grace and humility that was an example to us all. When President Kennedy challenged the nation to send a human to the moon, Neil Armstrong accepted without reservation.”
  • U.S. President Barack Obama | “Neil was among the greatest of American heroes – not just of his time, but of all time. When he and his fellow crew members lifted off aboard Apollo 11 in 1969, they carried with them the aspirations of an entire nation. They set out to show the world that the American spirit can see beyond what seems unimaginable – that with enough drive and ingenuity, anything is possible. And when Neil stepped foot on the surface of the moon for the first time, he delivered a moment of human achievement that will never be forgotten.”
  • Republican presidential candidate Mitt Romney | “Neil Armstrong today takes his place in the hall of heroes. The moon will miss its first son of Earth.”
  • House Speaker John Boehner (R-Ohio) | “Neil Armstrong blazed trails not just for America, but for all of mankind. He inspired generations of boys and girls worldwide not just through his monumental feat, but with the humility and grace with which he carried himself to the end.”
  • In the words of Neil Armstrong
  • “[The moon was] simply magnificent, beyond any visual experience that I had ever been exposed to.”
  • “In my own view, the important achievement of Apollo was a demonstration that humanity is not forever chained to this planet, and our visions go rather further than that, and our opportunities are unlimited.”
  • “I am, and ever will be, a white socks, pocket protector, nerdy engineer,” “And I take a substantial amount of pride in the accomplishments of my profession.”
  • “I can honestly say—and it’s a big surprise to me—that I have never had a dream about being on the moon”
  • The space race was “the ultimate peaceful competition: USA versus U.S.S.R. It did allow both sides to take the high road, with the objectives of science and learning and exploration.”
  • From his family
  • "Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.

NASA and Dinosaurs?



Credit: NASA/GSFC/Rebecca Roth

  • The low down
  • Footprints of ankylosaur have been found on the property of a NASA‘s Goddard Space Flight Center in Greenbelt, Maryland
  • Significance
  • Ankylosaur are members of the heavily-armored ankylosaur subgroup that lacked tail clubs but often sported prominent spike’s along their sides
  • At least two, possibly a mother and child tracks of two nodosaurs have been confirmed
  • A smaller print was discovered within the first, evidence that they were made around the same time and leading researchers to suggest it may have been a mother-and-child pair.
  • The track has started to erode, and may have been damaged by a lawnmower, the roughly 112-million-year-old track still shows four toe imprints
  • The tracks were found earlier this summer and recently NASA scientists were taken out to the site to see the fossil depression at that time
  • Researchers found several more possible dinosaur tracks, the NASA facility may have been founded on a Cretaceous dinosaur stomping ground.
  • Of Note
  • Officials are already moving to protect the fossil, and they plan to bring in paleontologists to look for other dinosaur tracks
  • What happens next will depend on the laws that regulate how fossils can be removed and curated.

Musical training as a child has a life long affect

  • A little music training in childhood goes a long way in improving how the brain function
  • The low down
  • Researchers for the first time have directly examined what happens after children stop playing a musical instrument after only a few years
  • Compared to peers with no musical training, adults with one to five years of musical training as children had enhanced brain responses to complex sounds
  • Making them more effective at pulling out the lowest frequency in sound crucial for speech and music perception, allowing recognition of sounds in complex and noisy auditory environments.
  • Significance
  • For the study, young adults with varying amounts of past musical training were tested by measuring electrical signals from the auditory brainstem in response to eight complex sounds ranging in pitch
  • Forty-five adults were grouped into three matched groups based on histories of musical instruction
  • One group had no musical instruction, another had 1 to 5 years the others had to 6 to 11 years
  • Both musically trained groups began instrumental practice around age 9
  • Musical training during childhood led to more robust neural processing of sounds later in life
  • The study suggests that short-term music lessons may enhance lifelong listening and learning
  • Of Note
  • Prior research on highly trained musicians and early bilinguals revealed that enhanced brainstem responses to sound are associated with heightened auditory perception, executive function and auditory communication skills.
  • The team believes that a few years of music lessons also confer advantages in how one perceives and attends to sounds in everyday communication situations, such as noisy restaurants

Smart Headlight



YouTube Channel : LabEquipment

  • The low down
  • In rain and snow conditions headlights reflect off of the precipitation back to driver
  • Carnegie Mellon professor and his team are working on ‘smart’ headlights that can streamlight in between the drops
  • Significance
  • The system consists of a co-located imaging and illumination system– camera, projector, and beamsplitter
  • The camera uses a 5 ms exposure time and the system has a total latency of 13 ms when the system runs at 120Hz. with an operating range about 13 feet in front of the headlights
  • The camera images the precipitation at the top of the field of view, the processor can tell where the drops are headed and sends a signal to the headlights, headlights then make their adjustments and react to dis-illuminate the particles all in about about 13 ms.
  • Simulations
  • Computer simulations predict system effectiveness for different systems set ups during a heavy rainstorm [25 mm/hr] on a vehicle traveling 30 km/hr
  • Simulations show that a system operating near 1,000 Hz, with a total system latency of 1.5 ms, and exposure time of 1 ms can achieve 96.8% accuracy, with 90% light throughput expected
  • The system would still have a significant [>= 70%] visibility improvement at 400 Hz
  • A prototype system has already validated simulations on laboratory-generated rain operating at 120 Hz
  • Simulations show that it is possible to maintain light throughput well above 90 percent for various precipitation types
  • Of Note
  • The prototype consists of a camera with gigabit ethernet interface (Point Grey, Flea3), DLP projector (Viewsonic, PJD62531), and desktop computer with Intel architecture (Intel i7 quad core processor).
  • The team says that it may take three to four more years of development and “commercializing it as a product will take additional years.”

New mineral in old rock

  • The low down
  • A meteorite that fell in 1969 as an exploding fireball in the skies over Mexico, scattered thousands of pieces of meteorites across the state of Chihuahua
  • It is largest carbonaceous chondrite ever found on our planet and is considered by many the best-studied meteorite in history
  • Scientists have now discovered a new mineral embedded in that meteorite
  • Panguite is an especially exciting discovery since it is not only a new mineral, but also a material previously unknown to science
  • The mineral could be among the first solid objects formed in our solar system, dating back to over 4 billion years ago, before the formation of Earth and the other planets.

Snake Oil
  • The low down
  • snakes naturally enlarge their own hearts by some 40 percent in two to three days after eating one of their huge but rare meals
  • A mix of compounds called fatty acids identified in pythons can spur an exercise-like boost in the size of mouse hearts
  • three fatty acids identified in the blood of Burmese pythons boosted the mass of a heart chamber in lab mice by 10 percent in just a week
  • Significance
  • Enlarging heart tissue can be a danger sign for humans
  • the growth seen in the mice looks more like an athlete’s healthful heart growth than a heart disease patient’s worrisome one
  • These ubiquitous compounds perform a variety of functions in reptiles and humans alike. Just the right mix of three of them — myristic, palmitic and palmitoleic acid — turns out to trigger a quick upsizing in heart muscle cells

Story of a Molten Asteroid

  • The low down
  • Lutetia and its asteroid cousins are thought to be relics from the early solar system
  • rocky fossils that have recorded a history of the solar system’s early days in their pits and fractures
  • In July 2010, the European Space Agency’s Rosetta spacecraft flew within 3,200 kilometers of Lutetia, peered at the asteroid and attempted to read its stony story.
  • Images from the OSIRIS camera reveal that parts of Lutetia’s surface are around 3.6 billion years old. Other parts are young by astronomical standards, at 50–80 million years old.
  • Astronomers estimate the age of airless planets, moons, and asteroids by counting craters.
  • Lutetia’s weak gravity tugged on Rosetta. The slight change in Rosetta’s path was reflected in radio signals received back at Earth
  • Significance
  • Scientists now think it is a leftover planetary seed, booted into the main belt
  • Lutetia turns out to have one of the highest densities of any known asteroid: 3400 kg per cubic metre.
  • The density implies that Lutetia contains significant quantities of iron, but not necessarily in a fully formed core.
  • The only explanation appears to be that Lutetia was subjected to some internal heating early in its history but did not melt completely and so did not end up with a well-defined iron core.

  • Nov 02, 1947 – 64 years ago : Spruce Goose – Howard Hughes piloted his huge wooden airplane, known as the Spruce Goose on its only flight, which lasted about a minute over Long Beach Harbor in California. It was the first test of a U.S. plane with eight engines. Wing span was 319 feet, 11 inches. Originally conceived by Henry J. Kaiser, a steelmaker and builder of Liberty ships, the aircraft was designed and constructed by Hughes and his staff. The original proposal for the enormous, 400,000-pound wooden flying boat, with its spectacular 320-foot wingspan, came from the U.S. government in 1942. The entire airframe and surface structures are composed of laminated wood (primarily birch, not spruce).

By design, the craft which was built in only 4 weeks. Biological data, the first data of its kind, was transmitted back to Earth while she lived. The data showed scientists how Laika was adapting to space – information important to the imminent planned manned missions. The 508-kg satellite remained in orbit 162 days. The true cause and time of Laika’s death was not made public until 2002, Laika likely died within hours after launch from overheating.
