Show Notes:

Possible New Cancer Drug

• A new study has developed a new drug, ZL105, that can manipulate the body\’s natural signalling and energy systems, allowing the body to attack and shut down cancerous cells
• Medicine Based on Precious Metals
• Platinum-based drugs are used in nearly 50% of all chemotherapeutic regimens, they damage DNA and cannot select between cancerous and noncancerous cells
• This new drug based on the precious metal iridium is specifically designed not to attack DNA and has a novel mechanism of action, means that it could not only dramatically slow down and halt cancer growth, but also significantly reduce the side effects
• Treatment
• Existing cancer treatments often become less effective after the first course, as cancer cells learn how they are being attacked, the newly developed drug is a catalyst and is active at low doses
• The energy-producing machinery in cancer cells works to the limit as it attempts to keep up with quick proliferation and invasion, this makes cancer cells susceptible to minor changes in the cell \’power-house\’
• This drug pushes cancer cells over the limit causing them to slow and shut down, whilst normal cells can cope with its effects
• It can attack cancer cells in multiple ways at the same time, so the cancer is less able to adapt to the treatment, which means the new drugs could be much more effective than existing treatments
• Effectiveness and the Future
• Preliminary data indicate that the novel drug may be ten times more effective in treating ovarian, colon, melanoma, renal, and some breast cancers, according to data obtained by the US National Cancer Institute
• Researchers now aim to expand the study to cancers that are inherently resistant to existing drugs and to those which have developed resistance after a first round of chemotherapy treatments.

A Possible New Dwarf Planet

• Astronomers have discovered a probable dwarf planet that orbits the Sun far beyond Pluto
• Discovery
• Astronomers been hunting for distant objects with the Dark Energy Camera, a 520-megapixel camera on the 4-meter Blanco telescope in Chile
• They captured 2012 VP113 during their first observing run, in November 2012, on the fifth image of the hundreds they would eventually snap, for months they tracked the object, until its full orbit became more apparent
• There have been a number of similar objects similar to this that have been found in the last decade that probably belong to the inner part of the Oort cloud
• **The New Object [2012 VP113] **
• The newfound object\’s official name is 2012 VP113, but the discovery team calls it VP for short, or just \’Biden\’ — after US Vice-President Joe Biden
• It is roughly 450 kilometers across, just one-fifth Pluto\’s, if Pluto were as big as a basketball, this new world a mere golf ball
• It\’s orbit takes it from 80 to 452 AU from the sun, never approaching Neptune (30 AU) or Pluto (39.5 AU).
• Pluto orbits the sun every 248 years, the new world requires 4340 years
• In several years time, after observations have pinned down its orbit, the scientists will submit a name for consideration by the International Astronomical Union (IAU)
• Origins
• Astronomers now have to come up with ideas to explain how these objects remain tightly gravitationally bound to the Sun when they orbit so far away.
• There are several competing ideas for how objects such as Sedna and 2012 VP113 got to where they are today
• One leading hypothesis proposes that in the Solar System’s infancy, a nearby star gravitationally perturbed the coalescing system and dragged some fragments out towards the edge
• Another possibility is that a massive rogue planet passed through at some point, kicking objects from the Kuiper belt outwards into the inner Oort cloud.

New Dinosaur Found in the Dakota’s

• Scientists unveiled the discovery, naming and description of a sharp-clawed, 500-pound, bird-like dinosaur that roamed the Dakotas with T. rex 66 million years ago
• New Dinosaur, Anzu
• Three partial skeletons of the dinosaur – almost making up a full skeleton – were excavated from the uppermost level of the Hell Creek rock formation in North and South Dakota
• Like many \”new\” dinosaurs, Anzu wyliei fossils were discovered some years ago, and it took more time for researchers to study the fossils and write and publish a formal scientific description
• The new dinosaur was 11.5 feet long, almost 5 feet tall at the hip and weighed an estimated 440 to 660 pounds
• Its jaws were tipped with a toothless beak, and its head sported a tall, rounded crest similar to that of a cassowary (a large ground bird native to Australia and New Guinea)
• The neck and hind legs were long and slender, also comparable to a cassowary or ostrich, the forelimbs of Anzu were tipped with large, sharp claws, and the tail was long and robust
• The researchers believe Anzu, with large sharp claws, was an omnivore, eating vegetation, small animals and perhaps eggs while living on a wet floodplain
• Studies of the rocks in which several of the most complete caenagnathid skeletons have been found show that these strata were laid down in humid floodplain environments
• Two skeletons show signs of trauma, one with a broken and healed rib, the other has an arthritic toe bone that may have been caused by an avulsion fracture (where a tendon ripped a piece off the bone to which it was attached).
• Whether these injuries were the result of combat between two individuals or an attack by a larger predator remains a mystery

— SPACECRAFT UPDATE—

European Space Agencies Cometary Spacecraft Rosetta

• ESA sent a wake-up call to the 100-kg (220-lb) lander riding aboard the Rosetta spacecraft, bringing it out of its nearly 33-month-long slumber and beginning its preparation for its upcoming
• Philae Lander
• The lander, Philae, will touch down on the surface of a comet in November of 2014 and is received a “personal wake-up call” from Earth, 655 million kilometers away.
• A confirmation signal from the lander was received by ESA five and a half hours after the initial signal was sent

Opportunity Rover Power Boost

• Opportunity rover on Mars has gotten a 70% boost in power over the past few weeks from a partial cleaning of dust from its solar panels
• Combined, with the seasonal effect and multiple dust-cleaning events have increased the amount of energy available each day from the rover\’s solar array by more than 70 percent compared with two months ago
• A good portion of that comes from the fact that its springtime in Mars’ southern hemisphere where Oppy now sits, so the Sun is now shining longer and higher in the sky.
• Several recent gusts of wind – or perhaps small dust devils – have also cleaned much of the dust off the rover’s solar panels.
• The rover team reported that between Sols 3605 and 3606 (March 15 and March 16, 2014), there was a dust cleaning event which resulted in about a 10% improvement in power production to 574 watt-hours, another cleaning event this week has put the power output to 615 watt-hours

— CURIOSITY UPDATE —

• Arriving at New Science Location
• The rover has reached a vantage point for its cameras to survey four different types of rock intersecting in an area called \”the Kimberley\”
• This is the spot on the map the team has been headed for, on a little rise that gives a great view for context imaging of the outcrops at the Kimberley
• The science team expects to take several weeks for observations, sample-drilling and onboard laboratory analysis of the area\’s rocks
• The mission\’s investigations at the Kimberley are planned as the most extensive since Curiosity spent the first half of 2013 in an area called Yellowknife Bay
• Researchers plan to use Curiosity\’s science instruments to learn more about habitable past conditions and environmental changes.

SCIENCE CALENDAR

Looking back

• April 9, 1959 : 55 years ago : First astronauts selected : NASA announced the selection of America\’s first seven astronauts for project Mercury. Scott Carpenter, Gordon Cooper, John Glenn, Gus Grissom, Wally Schirra, Alan Shepard and Donald Slayton were chosen from 110 applicants. Their training program at Langley, which ranged from a graduate-level course in introductory space science to simulator training and scuba-diving. Project Mercury, NASA\’s first high profile program, was an effort to learn if humans could survive in space. NASA required astronaut candidates to be male, not over 40 years old, not more than 5\’ 11\” height and in excellent physical condition. On 5 May 1961, Shepard became the first American in space

Mysterious ExoPlanet

• The gap in the cloud seen in the dust surrounding one star, probably arose when a planet under construction swept through the dust and debris in its orbit
• This small planet (6 to 28 times Earth’s mass) if we can confirm it, shouldn’t be there according to conventional planet-forming theory
• Current Formation Theories
• Seeing such a gap follows what we think we know about planetary formation
• You start with a cloud of debris and gas swirling around a star, then gradually the bits and pieces start colliding, sticking together and growing bigger into small rocks, bigger ones and eventually, planets or gas giant planet cores
• If there is a planet and there is no dust larger than a grain of sand farther out, that would be a huge challenge to traditional planet formation models
• How we Think it Should Have Formed vs. How it Appears
• This planet is far from its star, TW Hydrae, about twice Pluto’s distance from the sun
• TW Hydrae is a red dwarf star, which lies about 176 light-years from Earth in the constellation Hydra
• Given that alien systems’ age, that world shouldn’t have formed so quickly.
• Astronomers believe that Jupiter took about 10 million years to form at its distance away from the sun
• This planet near TW Hydrae should take 200 times longer to form because the alien world is moving slower, and has less debris to pick up
• TW Hydrae is only 55 percent as massive as our sun and is believed to be only 8 million years old.
• What This Might Mean
• Astronomers are seriously investigating other theories about how this potential planet can to be formed
• If we can actually confirm that there’s a planet there, we can connect its characteristics to measurements of the gap properties
• These observations will add to planet formation theories as to how you can actually form a planet very far out
• One alternative brought up in the press release: perhaps part of the disc collapsed due to gravitational instability
• If that is the case, a planet could come to be in only a few thousand years, instead of several million
• Direct collapse” theory, though: astronomers believe it takes a bunch of matter that is one to two times more massive than Jupiter before a collapse can occur to form a planet
• This world is no more than 28 times the mass of Earth, as best as we can figure and Jupiter itself is 318 times more massive than Earth
• There are also intriguing results about the gap, the dust grains in this system, orbiting nearby the gap, are still smaller than the size of a grain of sand
• Astronomers plan to use ALMA and the James Webb Space Telescope, which should launch in 2018, to get a better look

Non-Toxic Cancer Therapy Supplement

• A research team from the Hyperbaric Biomedical Research Laboratory at the University of South Florida has found that a combination of nontoxic dietary and hyperbaric oxygen therapies effectively increased survival time in a mouse model of aggressive metastatic cancer
• The research shows the effects of combining two nontoxic adjuvant cancer therapies, the ketogenic diet and hyperbaric oxygen therapy, in a mouse model of late-stage, metastatic cancer
• This study demonstrates potential cost-effective, nontoxic therapies to contribute to current cancer treatment regimens
• The Study
• Metastasis, the spreading of cancer from the primary tumor to distant spots, is responsible for over 90 percent of cancer-related deaths in humans
• In the study, mice with advanced metastatic cancer were fed either a standard high carbohydrate diet or carbohydrate-restricted ketogenic diet
• Mice on both diets also received hyperbaric oxygen therapy, which uses a special chamber to increase the amount of oxygen in the tissues
• Ketogenic Diet
• The ketogenic diet forces a physiological shift in substrate utilization from glucose to fatty acids and ketone bodies for energy
• Normal healthy cells readily adapt to using ketone bodies for fuel, but cancer cells lack this metabolic flexibility, and thus become selectively vulnerable to reduced glucose availability
• Hyperbaric Oxygen Therapy
• Solid tumors also have areas of low oxygen, which promotes tumor growth and metastatic spread
• Hyperbaric oxygen therapy involves breathing 100 percent oxygen at elevated barometric pressure, saturating the tumors with oxygen
• The Combination
• When administered properly, both the ketogenic diet and hyperbaric oxygen therapy are non-toxic and may even protect healthy tissues while simultaneously damaging cancer cells
• Both therapies slowed disease progression independently, animals receiving the combined ketogenic diet and hyperbaric oxygen therapy lived 78 percent longer than mice fed a standard high-carbohydrate diet

Buried Antarctic Mountain

• The British Antarctic Survey, Bedmap2 has used millions of new measurements of the frozen continent\’s surface elevation, ice thickness, and bedrock topography from a wide variety of sources collected over several decades
• The original Bedmap relied mostly on ground-based measurements, which limited the scientists in terms of how much land they could cover
• A NASA program called Operation IceBridge sends out airplanes that fly over the entire continent.
• The airplanes part of Operation IceBridge are equipped with lasers that measure the surface mountains\’ heights and other features, as well as ice-penetrating radar that maps subglacial bedrock-\”giving [scientists] a more 3-D picture of the ice sheet itself
• The new data has revealed several smaller features-both on Antarctica\’s surface and buried under the ice-that were missed in the previous Bedmap effort
• Scientists want to know the shapes of mountains and rocks to model how fast ice will move across these features on its way to the ocean, where the ice can melt and contribute to sea level rise

• Upgrades
• Planetary Resources Inc. (the proposed asteroid miners) announced a new “stretch goal” for its asteroid-hunting Arkyd-100 telescope on June 11
• Should they reach $2 million, double its original goal, they promises to equip the Arkyd telescope to look at star systems for exoplanets
• Giving the Arkyd this ability would require improving its stability systems and devoting time to study candidate stars
• Partnering with exoplanet researchers at MIT [the Massachusetts Institute of Technology, Arkyd would use two methods to hunt down planets
• Transiting, or seeing the dip in a star’s brightness when a planet passes in front of it
• Gravitational microlensing, or finding planets by measuring how the gravity of the star (and its planets) distorts light from stars and galaxies behind
• If it can raise $1.3 million, Planetary Resources proposes to build a ground station at an undisclosed “educational partner” that would double the download speed of data from the orbiting observatory
• Two more stretch goals will be revealed if Arkyd receives 11,000 backers and 15,000 backers

— CURIOSITY UPDATE —

• Answering Camera Questions
• The team has received a lot of questions about the cameras on the rovers and are now trying to answer some of them
• The Curiosity rover actually has 17 cameras on it, which is the most of any NASA planetary mission ever.
• Many of the black and white images that come back from the rover are black and white, or gray scale, because that\’s all the rover really needs in order to detect rocks and other obstacles
• Other cameras are color, such as the Mastcam imager, because the scientists use the color information to learn about the soil and the rocks
• There are 1-megapixel black and white imagers for the engineering cameras and 2-megapixel color imagers for the science cameras
• Camera Rundown
• MARDI, or the Mars Descent Imager, took pictures as the rover was landing on Mars
• MAHLI is the camera mounted on the end of the arm, and that takes close-up, high-resolution color photos
• Hazard avoidance cameras, or the HazCams, there are four of these in the front and four in the back, and they\’re used to take pictures of the terrain near the wheels and nearby the rover
• Mast Cameras, which are color imagers, which are used to do geology investigations
• Navigation Cameras, which take pictures that are used to drive the rover
• A remote microscopic imager, is part of the ChemCam laser instrument and is used to document the laser spots, that the rover makes on the surface
• Video
• In addition to the video taken when the rover was descending to the surface, the team has taken movies of the soil being shaken in the scoop
• Since video files are pretty large and because they have a limited downlink each day, the scientists prefer to take still images of new targets

SCIENCE CALENDAR

Looking back

• June (18?), 240 BC : 2253 years ago : Eratosthenes : A Greek astronomer and mathematician, estimated the circumference of the earth. As the director of the great library of Alexandria, he read in a papyrus book that in Syene, approaching noon on the summer solstice, the longest day of the year, shadows of temple columns grew shorter. At noon, they were gone. The sun was directly overhead. However, a stick in Alexandria, far to the north, could cast a pronounced shadow. Thus, he realized that the surface of the Earth could not be flat. It must be curved. Not only that, but the greater the curvature, the greater the difference in the shadow lengths. By measurement on the ground and application of geometry, he calculated the circumference of the earth.
