Were the dinosaurs covered by feathers or scales? Scientists disagree.
Were the dinosaurs covered by feathers or scales? Two scientists find that most had scales.
Palaeontologists Paul Barrett of the Natural History Museum in London and David Evans of the Royal Ontario Museum in Toronto created a database of all known impressions of dinosaur skin tissues. They then identified those that had feathers or feather-like structures, and considered relationships in the dinosaurian family tree.
The results, which Barrett revealed at the Society of Vertebrate Palaeontology’s annual meeting in Los Angeles in late October, indicate that although some ornithischians, such as Psittacosaurus and Tianyulong, had quills or filaments in their skin, the overwhelming majority had scales or armour. Among sauropods, scales were also the norm.
The uncertainty of science: Don’t bet any money on this result. The number of dinosaur fossils actually known is relatively tiny — making the overall database tiny as well — and further discoveries could change everything.

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Photos taken 33 years ago by a photographer who died in the Mt. St. Helens eruption have been discovered and developed.
Photos taken 33 years ago by a photographer who died in the Mt. St. Helens eruption have been discovered and developed.
Reid Blackburn took the photographs in April 1980 during a flight over the simmering volcano. When he got back to The Columbian studio, Blackburn set that roll of film aside. It was never developed. On May 18, 1980 — about five weeks later — Blackburn died in the volcanic blast that obliterated the mountain peak.
Those unprocessed black-and-white images spent the next three decades coiled inside that film canister. The Columbian’s photo assistant Linda Lutes recently discovered the roll in a studio storage box, and it was finally developed.

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

Obama’s top ten Constitutional violations for 2013.
The Obama administration’s top ten Constitutional violations for 2013.
The sad thing about this list is that it is incomplete, and it is only for 2013. Moreover, anyone who has been honestly following the news for the past five years will recognize most of these abuses. However, #9 was new to me, and just as egregious.
Responding to complaints about the University of Montana’s handling of sexual assault claims, the Department of Education’s Office of Civil Rights, in conjunction with the Justice Department, sent the university a letter intended as a national “blueprint” for tackling sexual harassment. The letter urges a crackdown on “unwelcome” speech and requires complaints to be heard in quasi-judicial procedures that deny legal representation, encourage punishment before trial, and convict based on a mere “more likely than not” standard.
Isn’t it nice how this administration is working hard to recreate Great Britain’s abusive and tyrannical Star Chamber?

Here come the Obamacare tax bills!
Finding out what’s in it: Here come the Obamacare tax bills!
The new taxes on one customer’s bill added up to $23.14 a month, or $277.68 annually, according to Kaiser Health News. It boosted the monthly premium from $322.26 to $345.40 for that individual. The new taxes and fees include a 2 percent levy on every health plan, which is expected to net about $8 billion for the government in 2014 and increase to $14.3 billion in 2018. There’s also a $2 fee per policy that goes into a new medical-research trust fund called the Patient Centered Outcomes Research Institute. Insurers pay a 3.5 percent user fee to sell medical plans on the HealthCare.gov Web site.
This list doesn’t include the hidden tax imposed on medical equipment that will also be passed on to customers.

No reason for the delay was announced. The rocket is an entirely new design, with an upper stage expected to cost less to make.

Insufficiently servile.
As he concludes,
So, that was my contact with the DoD police today. At every confrontation, they clearly expected me to respond with the appropriate degree of subservience, and were baffled and angered that I refused to do so. So, they couldn’t let it go. They just kept coming back to my office, as if repeated confrontations would make me more, rather than less, servile. And all this for something that wasn’t any sort of criminal offense.
It says a lot—none of it good—that the police seem to have the expectation of unquestioning obedience. It also says a lot that they seem used to getting it, which is our fault, not theirs.

Should Republicans again demand that the Obamacare individual mandate be delayed?
Should Republicans again demand that the Obamacare individual mandate be delayed?
I say, no. I say the Republicans should demand that Obamacare be repealed. Agreeing to delay the mandate only acts to cement other parts of the law into place, which is bad as there is literally nothing about this law that is good, for the country or for health care.
Moreover, agreeing to delay parts of Obamacare will then make the Republicans part of the problem. Better to force the Democrats to vote against repeal, even as the law unravels. The result in November can only be good, as this vote will provide conservatives with more ammunition during the election campaign.
Finally, by putting repeal up to a vote we might even be surprised and get enough votes to repeal. Obama would then veto that repeal, but the vote would set the precedent for further repeal votes down the line, when Obama is gone.

Mars Express will do an extremely close flyby of the martian moon Phobos on December 29.
Late this month, ESA’s Mars Express will make the closest flyby yet of the Red Planet’s largest moon Phobos, skimming past at only 45 km [28 miles] above its surface. The flyby on 29 December will be so close and fast that Mars Express will not be able to take any images, but instead it will yield the most accurate details yet of the moon’s gravitational field and, in turn, provide new details of its internal structure.

China’s rover about to go to sleep for the long lunar night.
China’s rover is about to go to sleep for the long lunar night.
According to Wu Fenglei of the Beijing Aerospace Control Center, the lander will “go to sleep” at about 7 a.m. on Christmas Day and the moon rover, Jade Rabbit, will fall asleep at about 1 a.m. on Boxing Day. The forthcoming lunar night, expected to begin on Dec. 26, will last for about two weeks, experts with the center estimated. During their “sleep”, both lander and rover will have to tolerate minus 180 degrees Celsius. Scientists tested the lander early Tuesday to ensure it can stand the temperature drop. Both lander and rover are stable, said Wu, adding they have completed a series of scientific tasks in the past two days.
This report states the rover landed in Sinus Iridum, the original announced landing site, contradicting other reports that said the lander came down in Mare Imbrium.

The sticker shock of Obamacare only begins when you pick your plan.
As a key enrollment deadline hits Monday, many people without health insurance have been sizing up policies on the new government health care marketplace and making what seems like a logical choice: They’re picking the cheapest one.
Increasingly, experts in health insurance are becoming concerned that many of these first-time buyers will be in for a shock when they get medical care next year and discover they’re on the hook for most of the initial cost.
In other words, the high premiums don’t cover most initial bills. You will have to pay the cost of most of your medical bills yourself.

This news report, confirmed by no other source, claims that the spacewalk this week was cut short because of water in the astronauts’ spacesuits.
I report this story but am very puzzled. If a water leak was the cause of the shortened spacewalks, I would have expected others to report that fact as well. No one has, however. (See this nasaspaceflight.com article, for example, which outlines the entire engineering situation quite thoroughly but says “both suits performed well during the EVA.”) Moreover, the ABC particular story above is written by someone who is not a space reporter, and contains some incongruities that reflect that, making me even more skeptical.

“An apparent double standard in President Barack Obama’s unprecedented crackdown on unauthorized leaks.”
Disclosures by lower-level officials have been vigorously pursued. For example, seven Navy SEALs were reprimanded for disclosing classified material to the makers of a military video game. Moreover, the administration has prosecuted a record number of intelligence community personnel for leaking.
Rarely, however, has the administration taken criminal action against senior officials for leaking.

Yesterday’s spacewalk on ISS, though successful, was cut short because of spacesuit discomfort issues unrelated to the earlier water leak problems.
No story on the spacewalk is entirely clear on the issues. Astronaut Rick Mastracchio was cold, but it seems he also had other problems that have not been outlined clearly. Interestingly he was not using the spacesuit that flooded in July. Michael Hopkins was using that suit and apparently had no problems.
In order to resize the spare suit on the station for Mastracchio they have delayed the next spacesuit for one day.
