NASA forces retraction of astronaut vision study due to privacy issues

9:01 pm

NASA has forced the retraction of an important science paper researching the damage to vision for astronauts on long spaceflights because of a concern the privacy of the astronauts might be violated.

According to the first author, the paper included information that could identify some of the astronauts that took part in the study — namely, their flight information. Although the author said he removed the identifying information after the paper was online, NASA still opted to retract it. But a spokesperson at NASA told us the agency did not supply the language for the retraction notice. The journal editor confirmed the paper was retracted for “research subject confidentiality issues,” but referred a question about who supplied the language of the notice back to NASA.

…According to first author Noam Alperin of the University of Miami Miller School of Medicine in Florida, the paper “Role of Cerebral Spinal Fluid in Space Flight Induced Ocular Changes and Visual Impairment in Astronauts” showed that visual damage caused by long space flights resulted from tiny shifts in the volume of spinal fluid — not vascular changes, as many experts had previously thought.

Protecting the health privacy of the astronauts is something NASA and the doctors that work with them are legally required to do. However, in this case the paper had been scrubbed of this information a long time ago. To force its retraction now when the actual. research was valid and important and the privacy of the astronauts was now protected seems an over reaction to me. Then again, NASA might be under legal pressure from the astronauts themselves, and thus forced to act.

The Danish National Symphony Orchestra – Star Trek Medley

6:01 pm

An evening pause: It is never a bad thing to listen to the music from Star Trek (though I would have preferred a larger percentage of this piece devoted to Alexander Courage’s original score).

Hat tip Willi Kusche.

Readers: If you want to contribute to Behind the Black, you can! I am in need of Evening Pause suggestions. If you haven’t suggested any before and want to now, comment here (without posting the link to your suggestion) and I will contact you!

Sunspot update for October 2017

9:23 am

NOAA today posted its monthly update of the solar cycle, covering sunspot activity for October. That graph is posted below, with annotations.

October 2017 Solar Cycle graph

The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction.

After two straight months of rising sunspot activity, the number of sunspots plunged in October, returning the numbers almost exactly back to the general trend we have seen since 2014 when the solar maximum ended. While the short two month increase indicated that the minimum will not occur as soon as this long term trend suggests, the quick return to that trend this month suggests that it will.

Meanwhile, November is six days old and has yet to see any sunspots at all.

Bezos sells another $1 billion in Amazon stock to fund Blue Origin

9:33 am

Capitalism in space: Repeating a stock sale he did in May, Jeff Bezos this week sold another million shares of his Amazon stock to raise another $1.1 billion in cash to finance his Blue Origin rocket company.

The stock sale reduced his holdings in Amazon by 1.3% to 16.4% total.

With this much cash available, Bezos has the luxury of developing and building his business with no help from the government and completely free to do whatever he wants. This freedom puts him in a very enviable position.

Canada’s Supreme Court rules against tribe in development dispute

9:20 am

In a case that appears similar to the dispute in Hawaii over the building of the Thirty Meter Telescope, Canada’s Supreme Court this week ruled against a local tribe in its more than quarter century battle to block the construction of a nearby ski resort.

The Ktunaxa Nation had opposed a resort on Crown land near their community in southeastern British Columbia, arguing that it would affect a grizzly-bear habitat and drive away the Grizzly Bear Spirit essential to their faith.

But, in a line that stunned some academic observers, seven judges of nine said that they looked on the religious-freedom claim under Section 2(a) of the Charter of Rights no differently than if it were made by non-Indigenous. They said the Ktunaxa claim fell entirely outside of the Canadian notion of freedom of religion, as established in previous Charter cases, which protects only the right to hold and manifest beliefs.

“In short, the Charter protects the freedom to worship, but does not protect the spiritual focal point of worship,” Chief Justice Beverley McLachlin and Justice Malcolm Rowe wrote for the seven judges. The court also affirmed that, while developers and government need to consult with Indigenous peoples and accommodate their concerns, the First Nations possess no veto power over development.

What I find interesting about this story is that the developer first proposed this ski resort in 1991, and has spent 26 years consulting and then fighting with the local tribes. Talk about stick-to-it-ness! Moreover, the insincerity and delaying tactics of one tribe are revealed by this quote:

It was only in 2009, the Supreme Court said, as the proposal appeared on the verge of approval, that the Ktunaxa first mentioned the Grizzly Bear Spirit and said that no accommodation was possible.

It is important to note that the land in question is privately owned by the resort, and that the tribe essentially wanted a full veto over the rights of that private owner to use their land as they wished. The Supreme Court ruled that the tribe does not have that right. Had it agreed to this demand, the court would have essentially given the tribe the power to rule over everyone else in Canada, on almost any issue the tribe wished. All they would have had to do is to come up with some religious excuse (as it appears they did here).

Astronomers find Kuiper Belt-like ring around Proxima Centauri

3:32 pm

Worlds without end: Astronomers have found a dusty ring 1 to 4 astronomical units from the nearest star, Proxima Centauri.

Because Proxima Centauri is a smaller, dimmer star, its system is more compact. Proxima b [the star’s known exoplanet] circles the star at 0.05 astronomical units (a.u., the average distance between Earth and the Sun) — for reference, Mercury orbits the Sun at 0.39 a.u. The dusty ring lies well beyond that, extending from 1 to 4 a.u.

The Proxima ring is similar in some ways to the Kuiper Belt, a cold, dusty belt in the far reaches of our solar system (beyond 40 a.u.) that contains a fraction of Earth’s mass. While the Kuiper belt is well known for larger members such as Pluto and Eris, it also contains fine grains, ground down through collisions over billions of years. The dust ALMA observed around Proxima Centauri is composed of similar small grains. The average temperature and total mass of the Proxima ring is also about the same as our Kuiper Belt.

Because the ring here much closer to the star than our Kuiper Belt, the material is much more densely packed. Moreover, the presence of both a ring and an exoplanet suggests more planets might remain undiscovered there, increasing the chances that this star could have a solar system very worthwhile exploring.

Today in fascist academia

11:12 am

Time to post this week’s list of stories outlining the fascist culture of the modern American campus. Since my last update, the stories have been more mixed, as there have not been many scheduled speaking events that would have prompted the brownshirts to move in and squelch our first amendment right to freedom of speech.

The last story needs highlighting because it illustrates the close-minded and willfully ignorant aspects of this college movement. These students are proud of their refusal to listen to other points of view, and want to encourage all students to stick their fingers in their ears and scream “La-la-la-la-la-la-la-la-la-la-la-la-la-la-la!” as loudly as possible to anything they disagree with. Worse, these are students, who are at the university to learn something. Instead, these know-nothing thugs are working so that everyone else will remain as ignorant as they are.

There was one small piece of good news: UCLA backs down from free speech confrontation. What happened is that UCLA has agreed to not charge the college’s Republican club exorbitant security fees for an upcoming Ben Shapiro speech.

The Bruin Republicans had protested the potential fee – charged if more than 30 percent of the audience is from outside the campus – as a tax on their free speech.

“Given UCLA’s commitment to free speech, and to avoid any appearance to the contrary,” said campus spokesman Tod Tamberg in an email, “UCLA has decided to also pay the basic security costs for this event. UCLA will be adopting this approach going forward while it reviews its current policy to ensure that it continues to be a useful planning tool for UCLA and registered student organizations.”

The sad part is that the university has to spend so much for security, illustrating how out of favor free speech remains at UCLA. Everyone expects the campus to erupt in violence simply because a conservative might get up and say something.

Tesla stock crashes due to possible loss of tax credit

10:13 am

The stock of Elon Musk’s Tesla electric car company crashed this week, dropping 7% on Wednesday, with the revelation that the Republican tax plan proposes eliminating the $7,500 tax credit for buying an electric car.

Its share price fell more than seven per cent to about $296 apiece from Wednesday’s $321. The draft law emerged as the Elon-Musk-led automaker announced its worst-ever quarter, recording a $671m loss and admitting it had not met its production target for its new Model 3 car, producing just 220 of them against its 1,500 target.

Economists believe that the tax credit is a key driver for electric car sales, and cite the example of when the state of Georgia cut its $5,000 tax credit and saw sales of electric cars slump from 1,400 a month to just 100 a month in response.

What this story highlights is that electric cars are simply not economical at this time, and that the government is distorting the market by pushing them. Without government aid, practically no one would buy them.

It would be far better for everyone to let the market decide. Not only would this save us tax dollars, it would allow the industry to focus its innovative efforts on upgrades that are cost effective and profitable, rather than on pie-in-the-sky fantasies that actually do no good at all.

Builders of Ghana’s first satellite push for government help

9:36 am

The new colonial movement: The student engineers who built Ghana’s first satellite, GhanaSat-1 and launched in July, are pushing their government to establish the legal framework for future space activities in that country.

Student engineers behind the successful launch of Ghana’s first satellite into orbit have appealed to the government to set up a multi-stakeholder committee to come up with an act, the Ghana outer space act, a key requirement that would enable the country to ratify and sign the United Nations Outer Space Treaty.

They said if the country signed and ratified the treaty, it would give investors the signal and confidence that the country was ready for them to come and establish space science facilities.

The description in the article of what these students want suggests they do not quite understand the ramifications of all the UN space treaties, because it appears they also want Ghana to become signatories to them all. This would be a big mistake. While every country that launches satellites is a signatory to the Outer Space Treaty, very few have signed the Moon Treaty, as its language puts far more serious restrictions on property rights.
