Coenzyme Q10 and Your Heart

  • Recent results from a multicentre randomised double blind trial shows that Coenzyme Q10 decreases all cause mortality by half
  • Making it the first drug to improve heart failure mortality in over a decade
  • Coenzyme Q10 (CoQ10)
  • Coenzyme Q10 (CoQ10) occurs naturally in the body and is essential to survival
  • It works as an electron carrier in the mitochondria, the powerhouse of the cells, to produce energy and is also a powerful antioxidant
  • CoQ10 levels are decreased in the heart muscle of patients with heart failure, with the deficiency becoming more pronounced as heart failure severity worsens
  • Double Blind Trial
  • Double blind controlled trials have shown that CoQ10 improves symptoms, functional capacity and quality of life in patients with heart failure with no side effects
  • Until now, no trials have been statistically powered to address effects on survival
  • The study randomised 420 patients with severe heart failure, into two groups with CoQ10 or placebo and followed them for 2 years
  • The primary endpoint was time to first major adverse cardiovascular event (MACE), unplanned hospitalisation due to worsening of heart failure, cardiovascular death, urgent cardiac transplantation and mechanical circulatory support
  • CoQ10 halved the risk of MACE, with 29 (14%) patients in the CoQ10 group reaching the primary endpoint compared to 55 (25%) patients in the placebo group
  • CoQ10 also halved the risk of dying from all causes, which occurred in 18 (9%) patients in the CoQ10 group compared to 36 (17%) patients in the placebo group
  • The CoQ10 treated patients also had significantly lower cardiovascular mortality and had a lower occurrence of hospitalisations for heart failure
  • There were fewer adverse events in the CoQ10 group compared to the placebo group
  • CoQ10 is the first medication to improve survival in chronic heart failure since ACE inhibitors and beta blockers more than a decade ago
  • Other heart failure medications block rather than enhance cellular processes and may have side effects
  • It\’s a Natural Substance
  • CoQ10 is a natural and safe substance, corrects a deficiency in the body and blocks the vicious metabolic cycle in chronic heart failure called the energy starved heart
  • It is present in food, including red meat, plants and fish, but levels are insufficient to impact on heart failure
  • It is currently sold over the counter as a food supplement but food supplements can influence the effect of other medications including anticoagulants, so patients should seek advice from their doctor before taking them`

Multiple Sclerosis Treatment

  • A phase 1 clinical trial for the first treatment to reset the immune system of multiple sclerosis (MS) patients showed the therapy was safe and dramatically reduced patients\’ immune systems\’ reactivity to myelin by 50 to 75 percent
  • Multiple Sclerosis
  • In MS, the immune system attacks and destroys myelin, the insulating layer that forms around nerves in the spinal cord, brain and optic nerve
  • When the insulation is destroyed, electrical signals can\’t be effectively conducted, resulting in symptoms that range from mild limb numbness to paralysis or blindness
  • The New Therapy
  • Current therapies for MS suppress the entire immune system, making patients more susceptible to everyday infections and higher rates of cancer
  • The new stops autoimmune responses that are already activated and prevents the activation of new autoimmune cells
  • The Trial
  • The MS patients\’ own specially processed white blood cells were used to stealthily deliver billions of myelin antigens into their bodies so their immune systems would recognize them as harmless and develop tolerance to them
  • While the trial\’s nine patients were too few to statistically determine the treatment, the study did show patients who received the highest dose of white blood cells had the greatest reduction in myelin reactivity
  • The primary aim of the study was to demonstrate the treatment\’s safety and tolerability
  • The intravenous injection of up to 3 billion white blood cells with myelin antigens caused no adverse effects in MS patients
  • The treatment did not reactivate the patients\’ disease and did not affect their healthy immunity to real pathogens
  • Researchers also tested patients\’ immunity to tetanus because all had received tetanus shots in their lifetime
  • One month after the treatment, their immune responses to tetanus remained strong, showing the treatment\’s immune effect was specific only to myelin
  • Phase 2 Trials
  • Human safety study sets the stage for a phase 2 trial to see if the new treatment can prevent the progression of MS in humans
  • The trial, which has already been approved in Switzerland
  • In the phase 2 trial researchers want to treat patients as early as possible in the disease before they have paralysis due to myelin damage
  • What Does It Do?
  • The patients\’ white blood cells are filtered out, specially processed and coupled with myelin antigens by a complex GMP manufacturing process
  • Then billions of these dead cells secretly carrying the myelin antigens were injected intravenously into the patients
  • The cells entered the spleen, which filters the blood and helps the body dispose of aging and dying blood cells
  • During this process, the immune cells start to recognize myelin as a harmless and immune tolerance quickly develops
  • This process may be useful for treating not only MS but also a host of other autoimmune and allergic diseases simply by switching the antigens attached to the cells
  • Another Possible Carrier
  • This therapy, recently published research in mice in which he used nanoparticles-rather than a patient\’s white blood cells-to deliver the myelin antigen
  • Using a patient\’s white blood cells is a costly and labor-intensive procedure
  • This new study showed the nanoparticles, which are potentially cheaper and more accessible to a general population, could be as effective as the white blood cells as delivery vehicles

Smart and Awesome LEGO

  • The Low Down
  • A recent tour of the Sony Computer Science Laboratories in Tokyo, found LEGO with cameras, motors and some rudimentary AI
  • Seen there was a motorized Lego platform controlled by a computer squared off against a platform controlled by a human with a PlayStation controller
  • The project is still in the experimental phase, so it will be awhile before it reaches the commercial level

Exoplanet Found By Small Telescopes

  • The Low Down
  • Tiny telescopes in Arizona and South Africa have spotted a Saturn-like planet in orbit around a star about 700 light-years from Earth.
  • The Kilodegree Extremely Little Telescope (KELT) and other ground-based tools spied the alien planet as it passed in front of its star
  • The planet, KELT-6b, can be seen from the surface of Earth for five hours as it transits
  • It has a year lasts only about 7.8 days, has no rings, and has a mass and size resemble the planet Saturn

Exoplanet Heft

  • A new study suggests that a large number of worlds found by NASA\’s Kepler alien planet-hunting space telescope are probably significantly larger than scientists previously estimated
  • What’s Going On
  • The Kepler Space Telescope has spotted more than 2,700 potential
  • Now researchers have made detailed follow-up observations of 300 of the stars Kepler found likely to be harboring exoplanets
  • One of the main findings of this initial work is that our observations indicate that most of the stars we observed are slightly larger than previously thought and one quarter of them are at least 35 percent larger
  • This also mean that any planets orbiting these stars must be larger and hotter as well, which could reduce the number of candidate Earth-size planet analogues detected by Kepler

— CURIOSITY UPDATE —

  • Curiosity will soon shift to a distance-driving mode headed for an area about 8 km / 5 mi away, at the base of Mount Sharp
  • The Mission Objective
  • The mission has also already accomplished its main science objective.
  • Analysis of rock powder from the first drilled rock target, \”John Klein,\” provided evidence that an ancient environment in Gale Crater had favorable conditions for microbial life
  • The rover team chose a similar rock, \”Cumberland,\” as the second drilling target to provide a check for the findings at John Klein
  • Scientists are currently analyzing laboratory-instrument results from portions of the Cumberland sample
  • Event
  • To reach the first area of investigation, Glenelg where it is now, the rover drove east about a 500 m / 0.3 mi from the landing site
  • No additional rock drilling or soil scooping is planned in the Glenelg area
  • To reach the next destination, Mount Sharp, Curiosity will drive toward the southwest for many months.
  • Although just because our end goal is Mount Sharp doesn\’t mean the team will not investigate interesting features along the way
  • Capabilities
  • One new capability being used is to drive away while still holding rock powder in Curiosity\’s sample-handling device to supply additional material to instruments later if desired by the science team
  • For the drilling at Cumberland, steps that each took a day or more at John Klein could be combined into a single day\’s sequence of commands far more efficiently
  • The team used the experience and lessons from our first drilling campaign, as well as new cached sample capabilities, to do the second drill
  • In addition, they increased the use of the rover\’s autonomous self-protection. This allowed more activities to be strung together before the ground team had to check in on the rover
  • Before the Road Trip Starts
  • The science team has chosen three targets for brief observations before Curiosity leaves the Glenelg area
  • The boundary between bedrock areas of mudstone and sandstone, a layered outcrop called \”Shaler\” which might be a river deposit.
  • And a pitted outcrop called \”Point Lake\” which might be volcanic or sedimentary.
  • A closer look at them could give us better understanding of how the rocks we sampled with the drill fit into the history of how the environment changed

SCIENCE CALENDAR

Looking back

  • June 13, 1983 : 30 years ago : Pioneer 10 : Space probe vehicle Pioneer 10 crossed the orbit of Neptune and became the first manmade object to leave our Solar System. It was launched 2 Mar 1972. It is moving in a straight line away from the Sun at a constant velocity of about 12 km/sec. Some 30 years after its launch, on 27 Apr 2002, NASA made successful contact with telemetry received from Pioneer 10 when it was at a distance from Earth of 7.57 billion miles, and the round-trip time for the signal (at the speed of light) was 22-hr 35-min. The probe sent information from the one scientific instrument that was still working, the Geiger Tube Telescope. The spacecraft is heading generally towards the red star Aldebaran, which forms the eye of Taurus (The Bull)
  • Voyager 1 launched on Sept 5, 1977 and overtook Pioneer 10 on Nov 17, 1998. It remains the most distant man-made object
  • Voyager 2 launched on Aug 20, 1977

Show Notes:

Heart Surgical Tech

  • The Tech
  • Many problems that once required sawing through the breastbone and opening up the chest for open heart surgery now can be treated through a tube
  • These minimal procedures used to be done just to unclog arteries and correct less common heart rhythm problems
  • Now some patients are getting such repairs for valves, irregular heartbeats, holes in the heart and other defects-without major surgery, Doctors even are testing ways to treat high blood pressure with some of these new approaches
  • Heart valves
  • Millions of people have leaky heart valves. Each year, more than 100,000 people in the United States alone have surgery for them
  • Without a valve replacement operation, half of these patients die within two years, yet many are too weak to have one.
  • Just over a year ago, Edwards Lifesciences Corp. won approval to sell an artificial aortic valve flexible and small enough to fit into a catheter and be wedged inside the bad one
  • At first it was just for inoperable patients. Last fall, use was expanded to include people able to have surgery but at high risk of complications.
  • Catheter-based treatments for other valves also are in testing. One for the mitral valve
  • It has had mixed review by federal Food and Drug Administration advisers this week; whether it will win FDA approval is unclear. It is already sold in Europe
  • Heart rhythm problems
  • Catheters can contain tools to vaporize or \”ablate\” bits of heart tissue that cause abnormal signals that control the heartbeat
  • Now catheter ablation is being used for the most common rhythm problem-atrial fibrillation, which plagues about 3 million Americans and 15 million people worldwide.
  • The upper chambers of the heart quiver or beat too fast or too slow. That lets blood pool in a small pouch off one of these chambers, clots can form in the pouch and travel to the brain, causing a stroke
  • Ablation addresses the underlying rhythm problem. To address the stroke risk from pooled blood, several novel devices aim to plug or seal off the pouch
  • A tiny lasso to cinch the pouch shut. It uses two catheters that act like chopsticks. One goes through a blood vessel and into the pouch to help guide placement of the device, which is contained in a second catheter poked under the ribs to the outside of the heart, then a loop is released to circle the top of the pouch where it meets the heart, sealing off the pouch.
  • A different kind of device sold in Europe and parts of Asia, but is pending before the FDA in the U.S is like a tiny umbrella pushed through a vein and then opened inside the heart to plug the troublesome pouch.
  • Early results from a pivotal study released by the company suggested it would miss a key goal, making its future in the U.S. uncertain.
  • Heart defects
  • St. Jude Medical Inc.\’s Amplatzer is a fabric-mesh patch threaded through catheters to plug the hole
  • In two new studies, the device did not meet the main goal of lowering the risk of repeat strokes in people who had already suffered one, but some doctors were encouraged by other results
  • Сlogged arteries
  • The original catheter-based treatment-balloon angioplasty-is still used hundreds of thousands of times each year in the U.S. alone
  • A Japanese company, Terumo Corp., is one of the leaders of a new way to do it that is easier on patients-through a catheter in the arm rather than the groin
  • Newer stents that prop arteries open and then dissolve over time, aimed at reducing the risk of blood clots, also are in late-stage testing
  • High blood pressure
  • About 1 billion people worldwide have high blood pressure, a major risk factor for heart attacks
  • Researchers are testing a possible long-term fix for dangerously high pressure that can\’t be controlled with multiple medications.
  • The new technology uses a catheter and radio waves to zap nerves, located near the kidneys, which fuel high blood pressure
  • At least one device is approved in Europe and several companies are testing devices in the United States
  • Pro\’s / Con\’s
  • Not everyone can have catheter treatment, and some promising devices have hit snags in testing
  • Others on the market now are so new that it will take several years to see if their results last as long as the benefits from surgery do.
  • This technology may also lead to cheaper treatment, although the initial cost of the novel devices often offsets the savings from shorter hospital stays
  • They also offer an option for people who cannot tolerate long-term use of blood thinners or other drugs to manage their conditions
  • These procedures have also allowed many people too old or frail for an operation to get help for problems that otherwise would likely kill them

New Age Estimate for the Universe

  • Launched by the European Space Agency in 2009, the Planck satellite scans the sky for the cosmic microwave background, radiation that dates back to about 380,000 years after the Big Bang
  • Now it has released the most detailed map ever created of the cosmic microwave background, echoes of the radiation from the Big Bang, was released revealing the existence of features that challenge the foundations of our current understanding of the Universe
  • New Detailed Map of the Cosmic Microwave Background
  • The image is based on the initial 15.5 months of data from Planck and is the mission\’s first all-sky picture of the oldest light in our Universe, imprinted on the sky when it was just 380 000 years old.
  • The red spots in the map are about 1 part in 100,000 hotter than the average temperature, while the blue spots are slightly colder which corresponds to regions of slightly different densities at very early times, representing the seeds of all future structure: the stars and galaxies of today
  • According to the standard model of cosmology, the fluctuations arose immediately after the Big Bang and were stretched to cosmologically large scales during a brief period of accelerated expansion known as inflation.
  • The theory of inflation says that around 10-30 seconds after the Big Bang, the universe briefly expanded faster than the speed of light.
  • At that time, the young Universe was filled with a hot dense soup of interacting protons, electrons and photons at about 2700ºC and protons and electrons joined to form hydrogen atoms, the light was set free
  • As the Universe has expanded, this light today has been stretched out to microwave wavelengths, equivalent to a temperature of just 2.7 degrees above absolute zero.
  • Planck is essentially a super sensitive thermometer that can probe the temperature of this radiation to millionths of a degree across the whole sky with greater resolution and sensitivity than ever before
  • By analysing the nature and distribution of the seeds in Planck\’s CMB image, we can determine the composition and evolution of the Universe from its birth to the present day
  • Because precision of Planck\’s map is so high, it also made it possible to reveal some peculiar unexplained features that may well require new physics to be understood
  • Since the release of Planck\’s first all-sky image in 2010, scientists have been carefully extracting and analysing all of the foreground emissions that lie between us and the Universe\’s first light revealing the cosmic microwave background in the greatest detail yet
  • New Findings
  • One of the most surprising findings is that the fluctuations in the CMB temperatures at large angular scales do not match those predicted by the standard model although their signals are not as strong as expected from the smaller scale structure
  • Another is an asymmetry in the average temperatures on opposite hemispheres of the sky, which runs counter to the prediction made by the standard model that the Universe should be broadly similar in any direction we look
  • For example a cold spot extends over a patch of sky that is much larger than expected.
  • The asymmetry and the cold spot had already been hinted at with Planck\’s predecessor NASA\’s WMAP mission, but were largely ignored because of lingering doubts about their cosmic origin
  • One way to explain the anomalies is to propose that the Universe is in fact not the same in all directions on a larger scale than we can observe
  • In this scenario, the light rays from the CMB may have taken a more complicated route through the Universe than previously understood, resulting in some of the unusual patterns observed today.
  • This data is an almost perfect fit of the standard model of cosmology, but with features that force us to rethink some of our basic assumptions
  • The ultimate goal of the project would be to construct a new model that predicts the anomalies and links them together, although scientists don\’t know whether this is possible and what type of new physics might be needed
  • Makeup of the Universe
  • The Planck data conform spectacularly well to the expectations of a rather simple model of the Universe, allowing scientists to extract the most refined values yet for its ingredients
  • Normal matter that makes up stars and galaxies contributes just 4.9% of the mass/energy density of the Universe
  • Dark matter, which has thus far only been detected indirectly by its gravitational influence, makes up 26.8%, nearly a fifth more than the previous estimate.
  • Dark energy, a mysterious force thought to be responsible for accelerating the expansion of the Universe, accounts for less than previously thought.
  • Expansion and Age of the Universe
  • Planck data also set a new value for the rate at which the Universe is expanding today, known as the Hubble constant at 67.15 kilometres per second per megaparsec, this is significantly less than the current standard value in astronomy
  • This data imply that the age of the Universe is 13.82 billion years, or 80 million years older than previously thought
  • The telescope is still making observations, and in about a year researchers will add more data
  • Multimedia
  • This graphic shows the same 10-square-degree patch of sky as seen by NASA’s Cosmic Background Explorer, or COBE, NASA’s Wilkinson Microwave Anisotropy Probe, or WMAP, and Planck.

Pint-Sized Paleontologist

  • A new species of crow-size pterosaur has been named Vectidraco daisymorrisae in honor of the nine-year-old fossil hunter who discovered it
  • The Discovery
  • While exploring the U.K.\’s Isle of Wight (off the S shore of the U.K.) in 2008, the then-five-year-old Morris came across blackened \”bones sticking out of the sand
  • The Morris family brought the fossil to paleontologist Martin Simpson at the University of Southampton, who, with the help of colleagues, identified it as a new species
  • Vectidraco daisymorrisae
  • In pterosaurs, certain parts of the skeleton, especially the skull and the pelvis, are really distinct between different species
  • The group of pterosaurs that it belonged to, ashdarchoids, were all are toothless, and many-perhaps all-were especially well adapted for life in terrestrial environments like woodlands, tropical forests, and floodplains
  • From the size of the pelvis the researchers estimate it had a wingspan of about 2.5 feet [75 cm] and was just over a foot [35 cm] long, or about the size of a gull or large crow.
  • This pterosaur lived around 145 to 165 million years ago
  • It probably had a head crest, was a reasonably good walker and runner on the ground, and could expertly fly through dense forests.
  • Of Note
  • This discovery has also inspired study co-author Simpson to write a children\’s book entitled Daisy and the Isle of Wight Dragon.

Robotic Snake

  • ”Robot Snakes”
  • Robot snakes have been developed in recent years to mimic the actions of their real life counterparts, able to travel over terrain in ways very similar to a real snake, and even to climb up objects such as a person\’s arm.
  • Now they have extended the capability of a robot snake to include wrapping and holding on to an object when thrown at it
  • Capabilities
  • Researchers were able to give the snake such an ability by making use of accelerometers embedded in its body
  • It\’s able to detect the sudden stop that occurs when it strikes an object, then takes advantage of programming that had already been done by the team to get it to wrap itself around the object that it had struck
  • There is a difference between wrapping and constricting, this robot \’wraps\’, it doesn\’t squeeze the target, it simply wraps itself around it to allow it to hold on

The Search for Apollo 11 Engines

  • Previously on SciByte
  • SciByte 40 | Apollo 11 and James Cameron – Apollo 11 Engines found at the bottom of the ocean | April 3, 2012
  • Apollo Engine Recovery Update
  • Last year, Amazon.com founder Jeff Bezos announced that he had located some of the Apollo F-1 rocket engines and planned to recover them
  • Now his Bezos Expedition team has been successful in recovering engines that helped power Apollo astronauts to the Moon and have now brought “a couple of your F-1s home”
  • Apollo Yes, but Apollo 11?
  • Last year he said they had found the engines from Apollo 11, but it may be been difficult to determine exactly which flight the ones found were from
  • NASA launched 65 F-1 engines, five per flight, on 13 Saturn V boosters between 1967 and 1973
  • Supposedly there would be serial numbers to make the identification of which flight these engines were from and the plaques are still on the ship, so perhaps the identification will come later
  • The Recovery
  • The team spend three weeks at sea working with remotely Operated Vehicles worked at a depth of more than 14,000 feet
  • These vehicles were tethered to a ship with fiber optics for data and electric cables transmitting power at more than 4,000 volts
  • Five F-1 engines were used in the 138-foot-tall S-IC, or first stage, of each Saturn V and each of the engines stands 19 feet tall by 12 feet wide and weigh over 18,000 pounds.
  • Bezos also revealed that his expedition had successfully raised enough parts for two engines
  • Where Might They Live?
  • All of the parts, recovered or still on the bottom of the ocean, still belong to NASA but NASA has agreed to work with the team to exhibit and restore the engines.
  • Bezos previously proposed displays at Smithsonian\’s National Air and Space Museum in Washington, D.C. and at The Museum of Flight in Seattle

— SPACECRAFT UPDATE—

GRAIL’s Resting Place

  • GRAIL Lunar probes
  • The probes\’ measurements have allowed scientists to create the best-ever gravity map of any celestial body and that map is getting better all the time, as researchers continue to analyze the data
  • The twin probes, which were each about the size of a washing machine, zipped around the moon at an average altitude of just 7 miles (11 km) in their final days
  • The two Grail spacecraft – known as Ebb and Flow – slammed into a mountain near the lunar north pole at 3,771 mph (6,070 km/h), striking the surface about 20 seconds apart
  • Update Announcement
  • NASA\’s Lunar Reconnaissance Orbiter (LRO) snapped a series of photographs of the two 16.5-foot-wide (5 meters) craters, which mark where the space agency\’s twin Grail probes ended their gravity-mapping mission, and their operational lives, on Dec. 17
  • Imaging
  • The craters themselves are small, nondescript features on a body riddled with impact scars and the LROC team found it surprise that they were able to find the craters at all
  • The Grail craters first showed up in LROC photos from January, but images taken on Feb. 28 show them in much greater detail
  • The team used these later photos to produce a topographic map of the impact zone
  • This map revealed that the two craters are separated by about 7,250 feet (2,210 m) in straight-line distance and 985 feet (300 m) in altitude
  • Ejecta
  • The crashes ejected material that appears darker than the surrounding lunar dirt, these may be dark due to spacecraft material being mixed with the ejecta
  • The darker material may also be residual fuel left in the probes\’ lines, or bits of their carbon-fiber bodies
  • Of Note
  • Although LRO didn\’t get any images of the actual crashes, which occurred in the dark ultraviolet imaging spectrograph did see emissions from mercury and atomic hydrogen in the ejected plumes when they rose high enough to reach sunlight and the analysis is ongoing

— CURIOSITY UPDATE —

  • New Technique for Searching for Water
  • The science team guiding NASA’s Curiosity Mars Science Lab (MSL) rover has now demonstrated a new capability that significantly enhances the robots capability to scan the surroundings for signs of life giving water from a distance
  • The Mastcam cameras can now also be used as a mineral-detecting and hydration-detecting tool to search 360 degrees around every spot it explores for the ingredients required for habitability and precursors to life mapping targets related to water that correspond to hydrated minerals
  • Scientists used the filter wheels on the Mastcam cameras to run an experiment by taking measurements in different wavelengths, thus serves as an early detective for water without having to drive up to every spot of interest, saving precious time and effort
  • The first use of the Mastcam 34 mm camera to find water was at the rock target called “Knorr\” it also saw elevated hydration signals in the narrow veins that cut many of the rocks in this area
  • These bright veins contain hydrated minerals that are different from the clay minerals in the surrounding rock matrix
  • The rover appears to have found that evidence for water at the Gale Crater landing site is also more widespread than prior indications.
  • But Mastcam has some limits it is not sensitive to the hydrated phyllosilicates found in the drilling sample
  • It is not sensitive to the hydrated phyllosilicates found in the drilling sample at John Klein
  • Curiosity\’s current location, Yellowknife Bay basin, possesses a significant amount of phyllosilicate clay minerals; indicating an environment where Martian microbes could once have thrived in the distant past.
  • April, the Month of Rest
  • Thanks also to Joshua C Wilder [@JWilder47] on Twitter for bringing this up as well
  • The positions of the planets in April will mean diminished communications between Earth and NASA\’s spacecraft at Mars as Mars will be passing almost directly behind the sun, from Earth\’s perspective. The sun can easily disrupt radio transmissions between the two planets during that near-alignment
  • To prevent an impaired command from reaching an orbiter or rover, mission controllers at NASA\’s Jet Propulsion Laboratory, Pasadena, Calif., are preparing to suspend sending any commands to spacecraft at Mars for weeks in April
  • The travels of Earth and Mars around the sun set up this arrangement, called a Mars solar conjunction, about once every 26 months, Mars solar conjunctions are not identical to each other. They can differ in exactly how close to directly behind the sun Mars gets, and they can differ in how active the sun is
  • Both orbiters will continue science observations on a reduced basis compared to usual operations. Both will receive and record data from the rovers.
  • Mars Exploration Rover Opportunity is approaching its fifth solar conjunction. Its team will send no commands between April 9 and April 26, although engineers anticipate some data dropouts the rover will continue science activities using a long-term set of commands to be sent beforehand, and the recorded data will be retransmitted later
  • Curiosity can also continue making science observations from the location where it will spend the conjunction period. Curiosity\’s controllers plan to suspend commanding from April 4 to May 1.
  • The Mars Reconnaissance Orbiter will go into a record-only mode on April 4.
  • NASA anticipates that the orbiter could have about 40 gigabits of data from its own science instruments and about 12 gigabits of data from Curiosity accumulated for sending to Earth around May 1.
  • Raw / Calibrated / White-Balance Image Comparison
  • The left image is the raw, unprocessed color, as it is received directly from Mars
  • The center rendering was produced after calibration of the image to show an estimate of \”natural\” color, or approximately what the colors would look like if we were to view the scene ourselves on Mars
  • The right image shows the result of then applying a processing method called white-balancing, which shows an estimate of the colors of the terrain as if illuminated under Earth-like, rather than Martian, lighting

Looking back

  • April 2, 1845 : 168 years ago : First photo of sun : The first surviving daguerrotype photograph showing details of the sun was taken by French physicists Armand Fizeau and Léon Foucault. The 5-inch (12 cm) image had an exposure of 1/60 second, [your eye takes ~1/3 sec to blink] and showed the umbra/penumbra structure of several sunspots, as well as limb darkening. The photographic process was new: Daguerre perfected the daguerrotype only a few years earlier, in 1838. Fizeau and Foucault had been collaborating with their own experiments on the process since 1839. Fizeau had much improved the durability of a daguerrotype image with a treatment, published in Aug 1840, using a solution of chloride of gold mixed with hypo-sulphite of soda, then heated over a spirit-lamp

Migrating Dinosaurs

  • The low down
  • studying chemical variations in the teeth of the chewing-challenged sauropod
  • When animals drink water, the oxygen in that water gets incorporated into the blood stream and eventually into tooth enamel
  • water from a mountain tarn and water from a lowland swamp will have different amounts of a particular form, or isotope, of oxygen that has two extra neutrons in its nucleus
  • Significance
  • oxygen isotopes extracted from the tooth enamel of eight fossils remains from the western United States, and then compared the enamel isotope levels to those of minerals found in nearby sediments
  • isotopic variation suggests, that they were moving around
  • Multimedia
  • By comparing the levels of a chemical tracer found in the enamel of sauropod teeth

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
  • many questions remain about how the snakes’ fatty acids actually work to trigger heart muscle cells to bulge

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.

SCIENCE CALENDER

Looking back this week
  • Nov 06, 1572 – 439 years ago : Tycho’s Supernova – A supernova was first noted in the W-shaped constellation of Cassiopeia but was seen by many observers throughout Europe and in the Far East. For two weeks it was brighter than any other star in the sky and visible in daytime. By month’s end, it began to fade and change colour, from bright white to yellow and orange to faint reddish light. It was visible to the naked eye for about 16 months
  • Nov 08, 1895 – 116 years ago : X-rays – Wilhelm Röntgen discovered X-rays during an experiment at Würzburg University
  • Nov 07, 1908 – 103 years ago : Single atom – Prof. Ernest Rutherford announced in London that he had isolated a single atom of matter
  • Nov 07, 1918 – 93 years ago : Goddard rocket – Goddard demonstrated a tube-launched solid propellant rocket, using a music stand as his launching platform,. Goddard began work for the Army in 1917 to design rockets to aid in the war effort.
  • Nov 04–05, 1922 – 89 years ago : Tutankhamen’s tomb – The entrance to King Tutankhamen’s tomb was discovered in Egypt in the Valley of the Kings where the English archaeologist Howard Carter had been making extended excavations. One of Carter’s labourers stumbled upon a stone step, the first step in a sunken stairway that ran down into the rock. Howard Carter excavated a further 11 steps and exposed a large part of a plastered and sealed doorway to Tutankhamun’s tomb in the Valley of the Kings near Luxor, Egypt. The tomb was the most complete ancient Egyptian royal tomb ever found.
  • Nov 07, 1940 – 71 years ago : Tacoma Narrows Bridge collapse – at approximately 11:00 am, the first Tacoma Narrows suspension bridge collapsed due to wind-induced vibrations. Situated on the Tacoma Narrows in Puget Sound, near the city of Tacoma, Washington, the bridge had only been open for traffic a few months. Video of Tacoma Narrows Bridge Collapse “Gallopin’ Gertie”
  • 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).
  • Nov 03, 1957 – 54 years ago : Laika – Sputnik 2 was launched, with the first live animal sent into space – a Siberian husky dog, Laika (“barker” in Russian). 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.
  • Nov 05, 1963 – 48 years ago : Vikings in America – Archaeologists found Viking ruins in Newfoundland predating Columbus by 500 years. Leif Ericson, Icelandic explorer, second son of Eric the Red, is believed by most historians to have been the first European to reach the North American mainland.
Looking up this week

  • Wednesday, Nov. 2 : 1st Quarter Moon

  • Thursday, Nov. 3 : Look lower left of the Moon this evening, by two or three fist-widths at arm’s length, for Fomalhaut, the Autumn Star.

  • Friday, Nov. 4 : Jupiter’s Great Red Spot should be crossing the planet’s central meridian.

  • Sat November 5, 2011 : The planet Saturn is quite low in the east at first light. It looks like a golden star, with the true star Spica to its lower right. Saturn’s largest moon, Titan, is visible through modest telescopes as a tiny “star” quite near Saturn.

  • Mars, the red planet, is a morning object among the stars of Leo during November

  • In the Southern Hemisphere : Mercury and Venus get together in the evening sky

  • Early November : The Taurids meteor shower is active in early November and although rates are not high with no well-defined peak, around five meteors per hour can be expected with hopefully some unusually bright and slow moving events. Although Eastern Europe and the Middle East are most favoured, it is essential that observers head out as soon as the Sun is a few degrees below the horizon also be aware you will

  • Saturday, Nov. 5 : Daylight-saving time ends (for most of North America) at 2 a.m. Sunday morning. Clocks “fall back” an hour.
