“Night, when words fade and things come alive. When the destructive analysis of day is done, and all that is truly important becomes whole and sound again.” –Antoine de Saint-Exupery
When you look out into the Universe, what is it that you typically think of? Do you think of reliable, fixed stars and constellations? The vast expanse of the Milky Way, with its memorable dust lanes and amorphous shapes?

Image credit: Roth Ritter (Dark Atmospheres), of the double cluster in Perseus.Maybe you think deeper and farther than that. Maybe you think about the distant galaxies and clusters, and the deepest deep-sky objects we know of. How the light took millions or even billions of years to reach us, and yet how every time we look at them, we see them exactly the same way.
Image credit: Misti Mountain Observatory.I couldn’t fault you for thinking like this; from mankind’s point of view, the Universe — for all intents and purposes — doesn’t change at all as we view it from one night to the next.But does that really mean the Universe isn’t changing?Let me flip this around on you: how much does anything here on Earth — you, your surroundings, even an entire, vibrant city — change in half-a-millisecond?
Image credit: DC User Forum, of a short-exposure shot with a Sony A900 DSLR.Not a whole lot, that’s for certain. You only change with the passage of time, and half-a-millisecond is just 0.00000000002% of a typical human lifetime. It’s too short of a timespan to notice any but the most catastrophic changes, and even then you have to look very closely.So why should you expect the Universe to change substantially over just 0.00000000002% of its lifetime? That’s how much of the Universe’s lifetime passes between one night on Earth and the next. And yet, if you looked at the right objects, you would be able to see meaningful changes from one night to the next.
Image credit: Tunc Tezel.The objects within our Solar System, for example, are close enough that we can see them moving from night-to-night. Objects closer to us — like Mars, in the foreground — appear to move more substantially than more distant objects like Uranus, visible in the background.The great cause of all this motion, of course, is our largest nearby clump of matter: the Sun. Objects like planets move at tens of kilometers-per-second relative to the Sun thanks to its gravity, while Sun-grazing comets can be accelerated up to speeds in the hundreds of kilometers-per-second. If you’re in the southern hemisphere, you may be able to get a good view of one now: Comet Lemmon.
Image credit: Rolf Wahl Olsen from Auckland, New Zealand.Green because of the carbon and nitrogen interacting with sunlight, this photo does an excellent job of tracking the stars from the Earth along with the Earth’s rotation. What you probably can’t tell is that the comet — with a photo exposure time of over an hour — is blurred.If instead of tracking the stars perfectly, we tracked the comet perfectly, know what we’d see?
Image credit: Peter Ward (Barden Ridge Observatory)That comet is moving relative to the stars behind it, and our ultra-close proximity to the comet makes it abundantly clear.But what you may not realize is that these “fixed” stars are also moving at tens-to-hundreds of kilometers-per-second relative to us, and relative to one another! It’s only the vast distances between us — measured in many light-years — that make it impossible to detect these changes from night-to-night.But we can’t really detect changes in ourselves from millisecond-to-millisecond; you simply need to look on longer timescales!
Image credit: Martha Haynes of Cornell University.The stars in our night sky shift positions by many kilometers each second. From night-to-night we might not be able to tell the difference, but just as you or I look different when we go weeks without cutting our hair, we can see just how the Universe changes over long enough timescales.
There are gas clouds and stellar remnants tearing through the interstellar medium at these same speeds, including some that move at thousands of kilometers-per-second, even approaching 1% the speed of light!
Image credit: NASA/ESA/Hubble Heritage Team and CTIO.There are new stars being born — where nuclear fusion ignites for the first time — and stars that run out of fuel, dying in either a planetary nebula or a supernova explosion, depending on the properties of the star.

Image credit: Peter Nugent/Palomar Transient Factory.When you look up at the Universe, it may appear static and unchanging, but that’s only because these objects are so far away and our human experiences are so short in comparison with the age of the Universe.But stick around for a while, and even the most mundane of objects will change for you. Fuel burns, elements fuse, gravity pulls, and physics happens. Just give it time, and you’ll see it for yourself.We may only be around for a snapshot of it, but make no mistake, it’s never the same from moment-to-moment. From the way I look at it, there isn’t any doubt about it: the Universe is alive.
Researchers print see-through electronics onto PAPER
Scientists have used one of the simplest, ordinary materials to create the latest and flattest in electronics – paper.
Researchers at the University of Maryland have taken the first step towards green, flexible electronics by printing transparent electronics onto ‘nanopaper,’ created from wood pulp treated with enzymes and mechanically beaten.
They developed the transistor on the surface of the nanopaper by printing three different inks on it.
Researchers have taken the first steps toward green, flexible electronics by developing nanopaper, on which a transistor can be printed
In their paper Highly Transparent and Flexible Nanopaper Transistor published on January 25, the researchers explained that the transistor had ‘unique properties, such as flexibility, cost efficiency, lightweight and renewability’ and that the field of ‘green electronics’ was becoming an emerging field of research with commercial interest.
The transistor is 84 per cent transparent and malleable, allowing it to still perform when slightly bent. The nanopaper is It is thin enough to be cut or folded leading the way for foldable electronics.
Nanotubes (pictured), single atomic sheets of carbon rolled up into a tube, are printed on the nanopaper along with a dielectric ink and a semiconducting ink to create the transistor
Researcher Liangbing Hu said the nanopaper is ‘as flat as plastic’
Researcher Liangbing Hu, quoted by Extreme Tech, said: ‘It’s as flat as plastic.’
The report wrote: ‘The device configuration can be applied to many other semiconductor materials toward flexible green electronics.’
Printed on the nanopaper was a layer of carbon nanotubes, a dielectric ink, a semiconducting ink and another layer of nanotubes.
Carbon nanotubes are single atomic sheets of carbon rolled up into a tube and are 10,000 times smaller than a strand of human hair.
Their next challenge for researchers will be to devise a way to print the nanopaper on a commercial, mass production scale.
The breakthrough has come after researchers at IBM revealed a new technique that could one day replace silicon in computer chips, making them dramatically smaller and faster.
For the first time, the team revealed they have created a carbon ‘chip’ with more than ten thousand working transistors made of nano-sized tubes of carbon, which have been precisely placed and tested in a single.
The researchers from the University of Maryland (pictured) say their transistor is flexible, cost effective, lightweight and renewable
The problems faced by color blindness sufferers could be solved thanks to new glasses that can allow them to see the full spectrum for the first time, it was claimed today.
Around 8% of men and a smaller number of women suffer from ‘red-green deficiency’, a genetic abnormality that restricts them from seeing some reds and greens.
But the new lenses, which were originally intended to help medics locate veins and bruising more easily, can help sufferers beat the disability and distinguish colors they were formerly unable to.

The revolutionary new glasses help the color blind see colors they previously could not
The invention by U.S. research institute 2AI Labs builds on research by cognitive scientist Mark Changizi, a specialist in evolutionary neurobiology.
He suggested in 2006 that humans developed the ability to observe subtle changes in skin color, like blushes, to detect social cues and work out the emotions of peers.
But 2AI’s labs glasses were not intended to restore this function in those deficient of it, but rather to help doctors and nurses detect ‘oxygenated blood’ in the skin.
It was hoped that the glasses could used to help medics see bruising that was not immediately visible and find veins before taking blood.
But in tests the lenses – dubbed Oxy-Iso – was shown to help the color blind distinguish parts of the spectrum they were previously unable to.
Can you see this number? The Ishihara Color Test is the standard way to diagnose color blindness
On his blog, Professor Changizi said: ‘Although we didn’t design our technology with color-deficients specifically in mind, we weren’t too surprised that the Oxy-Iso may help with with red-green color-deficiency.
‘As I have argued in my research and my earlier book, Vision Revolution, our human variety of color vision evolved — above and beyond that found in other mammals — in order to sense these oxygenation variations, allowing us to sense color-signals on the skin (including blushes, blanches, as well as sensing health).
‘So the Oxy-Iso filter concentrates its enhancement exactly where red-green color-blind folk are deficient.’
Daniel Bor, a researcher from the University of Sussex, said wearing the glasses enabled him to pass the commonly used test for color blindness, the Ishihara Color Test, in which patients are shown plates which feature a circle of dots.
Color blindness sufferers are not able to make out numbers shown made up of dots of a different color.
‘When I first put one of them on, I got a shiver of excitement at how vibrant and red lips, clothes and other objects around me seemed,’ Mr Bor said.
The glasses are already available. However, while they enhance perception of reds and greens, they hamper the ability to distinguish yellows and blues.
A cure for sausage fingers: Clip-on tips which spell an end to smartphone typos
Do your fat fingers mean you make embarrassing spelling mistakes when you tap out a text on your phone?
If so, help is – literally – at hand, in the form of supplementary tips for your fingers.
The new accessory, called Tech Tips, come in different sizes to fit on to fingertips of any width and even over thick gloves – providing perfect contact with phones and tablets.
Scroll down for video
Fat-fingered texters can save their blushes with a fingertip extension that makes using a touchscreen much easierThe product, available in packs of four priced $9.99 (£6.30) from www.usetechtips.com, proved a hit at the Consumer Electronic Show 2013 in Las Vegas.
And they’re already being snapped up by touchscreen phone and tablet users from around the world struggling to get to grips with the technology.
The creation is the brainchild of Sri Vellanki, who came up with the idea after finding it tough to use her iPhone with long fingernails.
If you don’t fancy the Tech Tips on the end of your fingers, you can buy gloves that are specially made to interact with your smartphone’s touchscreen
Ms Vellanki, originally from India but now living in Montana, USA, said: ‘I got my first iPhone in 2011 and I was having problems because it always had to make skin contact and my nails didn’t work.
‘I thought I could make an electrically conductive nail polish and easily fix the problem but it turned out to be more complicated than that.
‘So I figured out what had to be done to make a very small stylus that was comfortable, economical and extremely accurate.
‘I had a working prototype based on guitar fingerpick within a month and it took me about a year from that point to get the first Tech Tips styluses manufactured.
‘I used a mechanical engineering firm to help bring my prototype into a product that could be manufactured easily.
‘I had 3D prototypes done to make sure that Tech Tips were comfortable and made to fit different sized hands, from those of a young child to a large man.
‘We even have large enough sizes to fit over a glove so that you can actually text without taking your glove off. There are six sizes from XS to XXL.
‘So far we have had loads of interest and a fantastic response at the Consumer Electronic Show 2013 in January which is where we launched our products.
‘Everyone from large retailers, educational institutions and large corporations showed significant interest.
She added: ‘The nail had to look nice, I didn’t want women to have to compromise.’
Many pro-aborts try to flip the label of pro-life on us, calling us anti-abortion or anti-choice. They don’t want the reminder out there that abortion is ending a life. But one pro-abortion blogger at Salon, Mary Elizabeth Williams, is going a different route. She readily admits that abortion ends a life… and that’s A-OK.
Her response to the question of abortion ending a life? So what?
Here’s the complicated reality in which we live: All life is not equal. That’s a difficult thing for liberals like me to talk about, lest we wind up looking like death-panel-loving, kill-your-grandma-and-your-precious-baby storm troopers. Yet a fetus can be a human life without having the same rights as the woman in whose body it resides. She’s the boss. Her life and what is right for her circumstances and her health should automatically trump the rights of the non-autonomous entity inside of her. Always.
… When we try to act like a pregnancy doesn’t involve human life, we wind up drawing stupid semantic lines in the sand: first trimester abortion vs. second trimester vs. late term, dancing around the issue trying to decide if there’s a single magic moment when a fetus becomes a person. Are you human only when you’re born? Only when you’re viable outside of the womb? Are you less of a human life when you look like a tadpole than when you can suck on your thumb?
… My belief that life begins at conception is mine to cling to. And if you believe that it begins at birth, or somewhere around the second trimester, or when the kid finally goes to college, that’s a conversation we can have, one that I hope would be respectful and empathetic and fearless. We can’t have it if those of us who believe that human life exists in utero are afraid we’re somehow going to flub it for the cause. In an Op-Ed on “Why I’m Pro-Choice” in the Michigan Daily this week, Emma Maniere stated, quite perfectly, that “Some argue that abortion takes lives, but I know that abortion saves lives, too.” She understands that it saves lives not just in the most medically literal way, but in the roads that women who have choice then get to go down, in the possibilities for them and for their families. And I would put the life of a mother over the life of a fetus every single time — even if I still need to acknowledge my conviction that the fetus is indeed a life. A life worth sacrificing.
A life worth sacrificing. An unborn baby is indeed a life…a life which matters only if the mother finds it convenient. If the mother finds the pregnancy inconvenient, then it’s no big deal at all to end that life.
And she calls pro-lifers diabolical.
Of course, there’s something she’s getting wrong. Abortion isn’t sacrificing a life. Sacrificing a life requires willingness, for someone to stand up and say, Yes, I am willing to die for you. A mother absolutely can make a sacrifice to save the life of her unborn child – Chiara Corbella is a heart-breaking example – but an unborn child cannot be “sacrificed” for his or her mother. An unborn baby does not have a say in the decision to have an abortion; an unborn baby does not choose to die. Abortion is not a sacrifice. It’s murder. Let’s get that straight.
While Williams claims she does not want to come across as a “death-panel-loving, kill-your-grandma-and-your-precious-baby storm trooper,” that’s exactly what she’s done. Some lives are worth more than others? Said every eugenicist, totalitarian dictator, and murderer who’s ever existed. That is the mindset that says it’s acceptable for parents to euthanize their disabled children, or that the elderly can be killed without their consent. By this same logic, infanticide should be completely acceptable as well. Heck, a mother should be allowed to kill her ten-year-old, too, if the mother decides that that child’s life is worth sacrificing.
It would be interesting to know who exactly gets to decide which lives are worthy to continue living, and which are not, since according to Williams, some lives are worth more than others. Are the disabled worthy of living? The elderly? The poor? Who decides? If not all humans are worthy of life, then who decides which get to live and which are sentenced to die?
I also want to point out the inherent narcissism of Williams’s argument. Not only is it acceptable to kill your unborn child merely out of inconvenience, but to Williams, it’s something worth sacrificing. How self-absorbed and narcissistic must you be to see the murder of your child as a noble, worthy sacrifice? It’s as if she thinks the baby would willingly agree to be slaughtered so Mommy doesn’t have to deal with the hassle of having a baby. That takes a seriously warped mind.
Pro-aborts will surely be cursing this article for drawing back the curtain and exposing the grisly truth about abortion. It doesn’t actually matter what people say regarding whether the unborn baby is a human life. Science has already established that it is. The question is whether or not women should have the right to take that life. And while abortion activists usually try to avoid the truth, Williams has brought it, like maggots festering underneath a rock, unflinchingly to the light for all to see.
Iraq war veteran who lost all four limbs in blast proudly shows off his double arm transplant
An Iraq veteran who lost all four limbs in a roadside bombing in Iraq almost four-years ago said today he’s looking forward to driving and swimming after undergoing a double-arm transplant.
‘I just want to get the most out of these arms, and just as goals come up, knock them down and take it absolutely as far as I can,’ Brendan Marrocco said Tuesday.
The 26-year-old New Yorker spoke at a news conference at Johns Hopkins Hospital, where he was joined by surgeons who performed the arduous and complex 13-hour operation.

U.S. Army Sgt. Brendan Marrocco of Staten Island, New York, who lost his four limbs in a 2009 roadside bomb attack in Iraq, speaks during a news conference after receiving double arm transplants, performed at John Hopkins Hospital
After he was wounded, Marrocco said, he felt fine using prosthetic legs, but he hated not having arms.
‘You talk with your hands, you do everything with your hands, basically, and when you don’t have that, you’re kind of lost for a while,’ he said.
Marrocco said his chief desire is to drive the black Dodge Charger that’s been sitting in his garage for three years.
‘I used to love to drive,’ he said. ‘I’m really looking forward to just getting back to that, and just becoming an athlete again.’

Although he doesn’t expect to excel at soccer, his favorite sport, Marrocco said he’d like to swim and compete in a marathon using a hand-cycle.
Marrocco joked that military service members sometimes regard themselves as poorly paid professional athletes.
His good humor and optimism are among the qualities doctors cited as signs he will recover much of his arm and hand use in two to three years.
‘He’s a young man with a tremendous amount of hope, and he’s stubborn – stubborn in a good way,’ said Dr. Jaimie Shores, the hospital’s clinical director of hand transplantation. ‘I think the sky’s the limit.’
Shores said Marrocco has already been trying to use his hands, although he lacks feeling in the fingers, and he’s eager to do more as the slow-growing nerves and muscles mend.
‘I suspect that he will be using his hands for just about everything as we let him start trying to do more and more. Right now, we’re the ones really kind of holding him back at this point,’ Shores said.
The procedure was only the seventh double-hand or double-arm transplant ever done in the United States.
The infantryman was injured by a roadside bomb in 2009. He is the first soldier to survive losing all four limbs in the Iraq War.

Marrocco also received bone marrow from the same donor to minimize the medicine needed to prevent rejection.
He said he didn’t know much about the donor but ‘I’m humbled by their gift.’
The 13-hour operation on December 18th was led by Dr. W.P. Andrew Lee, plastic surgery chief at Hopkins.-
Marrocco was being released from the hospital Tuesday but will receive intensive therapy for two years at Hopkins and then at Walter Reed National Military Medical Center in Bethesda.
After a major surgery, human nerves regenerate at a rate of an inch per month, Lee said.
‘The progress will be slow, but the outcome will be rewarding,’ he added.
The infantryman also received bone marrow from the same dead donor who supplied his new arms. That novel approach is aimed at helping his body accept the new limbs with minimal medication to prevent rejection.
The military sponsors operations like these to help wounded troops. About 300 have lost arms or hands in Iraq or Afghanistan.

The surgical team led by Johns Hopkins physicians performed the institutions first bilateral arm transplant, together with an innovative treatment to prevent rejection of the new limbs
Unlike a life-saving heart or liver transplant, limb transplants are aimed at improving quality of life, not extending it. Quality of life is a key concern for people missing arms and hands — prosthetics for those limbs are not as advanced as those for feet and legs.
‘He was the first quad amputee to survive,’ and there have been four others since then, Alex Marrocco said.
The Marroccos want to thank the donor’s family for ‘making a selfless decision … making a difference in Brendan’s life,’ the father said.
Brendan Marrocco has been in public many times. During a July 4 visit last year to the Sept. 11 Memorial with other disabled soldiers, he said he had no regrets about his military service.
‘I wouldn’t change it in any way. … I feel great. I’m still the same person,’ he said.
Lee led three of those earlier operations when he worked at the University of Pittsburgh, including the only above-elbow transplant that had been done at the time, in 2010.
Marrocco’s ‘was the most complicated one’ so far, Lee said in an interview Monday. It will take more than a year to know how fully Marrocco will be able to use the new arms.
‘The maximum speed is an inch a month for nerve regeneration,’ he explained. ‘We’re easily looking at a couple years’ until the full extent of recovery is known.
While at Pittsburgh, Lee pioneered the immune-suppression approach used for Marrocco. The surgeon led hand-transplant operations on five patients, giving them marrow from their donors in addition to the new limbs.
This photograph from December 18th shows the surgical team at Johns Hopkins Hospital during their 13-hour operation on Brendan Marrocco
All five recipients have done well, and four have been able to take just one anti-rejection drug instead of combination treatments most transplant patients receive.
Minimizing anti-rejection drugs is important because they have side effects and raise the risk of cancer over the long term. Those risks have limited the willingness of surgeons and patients to do more hand, arm and even face transplants.
Lee has received funding for his work from AFIRM, the Armed Forces Institute of Regenerative Medicine, a cooperative research network of top hospitals and universities around the country that the government formed about five years ago.
With government money, he and several other plastic surgeons around the country are preparing to do more face transplants, possibly using the new immune-suppression approach.

Marrocco expects to spend three to four months at Hopkins, then return to a military hospital to continue physical therapy, his father said.
Before the operation, he had been fitted with prosthetic legs and had learned to walk on his own.
He had been living with his older brother in a specially equipped home on New York’s Staten Island that had been built with the help of several charities.
Shortly after moving in, he said it was ‘a relief to not have to rely on other people so much.’
The home was heavily damaged by Superstorm Sandy last fall.
Despite being in a lot of pain for some time after the operation, Marrocco showed a sense of humor, his father said.
He had a hoarse voice from the tube that was in his throat during the long surgery and decided he sounded like Al Pacino. He soon started doing movie lines.
‘He was making the nurses laugh,’ Alex Marrocco said.

How a beetle can use the stars to navigate its way across the vast deserts of Africa
It might look small and insignificant but the dung beetle has its sights set firmly on the stars.
The beetle is the first insect proven to use the light of the Milky Way to help steer its course.
Also known as the scarab, the tiny creatures feed on animal droppings, which they fashion into a ball and roll away to a safe spot where it is less likely to be stolen.
New research has found that scarabs – also known as dung beetles – find their way through their desert habitat by using the stars of the Milky Way as a reference
Although their eyes are too weak to distinguish individual constellations, scientists found they used the glow of the Milky Way to navigate in a straight line, ensuring they do not circle back to the dung-heap and potential competitors.
‘Even on clear, moonless nights, many dung beetles still manage to orientate along straight paths,’ said Dr Marie Dacke from Lund University in Sweden.
‘This led us to suspect that the beetles exploit the starry sky for orientation – a feat that had, to our knowledge, never before been demonstrated in an insect.’
Field experiments on a South African game reserve showed that the beetles were able to roll their dung balls along straight paths under starlit skies, but not in overcast conditions.
The lighter band of the Milky Way’s edge: While unable to pick out constellations, the scarabs could detect the light arcing over their heads
For the tests, the beetles were fitted with tiny cardboard caps to alter their field of vision.
They were placed in a circular arena surrounded by a meter-high black cloth, making it impossible for them to see landmarks.
With no moon, it took much less time for the beetles to roll a dung ball from the center of the arena to the edge when they were able to see the sky.
When they could not look up, the time taken increased from 40 seconds to 124 as they wandered aimlessly around.
The experiment was repeated in a Johannesburg planetarium, with similar results.
The beetles performed equally well under a full sky of stars, and when only the glow of the Milky Way was visible.
Most stars would be too dim for the beetles’ tiny compound eyes to see, said the researchers. While unable to pick out constellations, the scarabs could detect the light of the Milky Way arcing over their heads.
‘This finding represents the first convincing demonstration for the use of the starry sky for orientation in insects and provides the first documented use of the Milky Way for orientation in the animal kingdom,’ the researchers wrote in the journal Current Biology.
Previously only birds, seals and humans were known to navigate by the stars.
Dung beetles also use the sun and moon as compass cues, said the scientists.
They added: ‘Although this is the first description of an insect using the Milky Way for their orientation, this ability might turn out to be widespread in the animal kingdom.’
The orbital balloon: NASA tests blow-up space-craft
A prototype inflatable module is to be tested aboard the International Space Station to give astronauts an extra bedroom, NASA has announced.
The inflatable module can be compressed into a 7ft tube for delivery, and is being heralded as a key component of future exploration and the development of commercial space travel and research.
It is designed by Bigelow Aerospace, based in Las Vegas, which has been awarded a $17.8 million (£11m) test project for the inflatable room – and hopes to develop space hotels and even planetary bases using the technology.

Astronauts will test the ability of the bladder, known as the Bigelow Expandable Activity Module, or BEAM, to withstand heat, radiation, debris and other assaults.
Some adventurous scientists might also try sleeping in the spare room, which is the first piece of private property to be blasted into space, NASA said.
Lori Garver, NASA’s deputy administrator, said as she unveiled the contract award that the inflatable module concept is simultaneously cutting edge technology and affordable.
‘This partnership agreement for the use of expandable habitats represents a step forward in cutting-edge technology that can allow humans to thrive in space safely and affordably, and heralds important progress in U.S. commercial space innovation,’ she said.
‘The International Space Station is a unique laboratory that enables important discoveries that benefit humanity and vastly increase understanding of how humans can live and work in space for long periods.’
Part of NASA’s interest in the inflatable technology is prompted by its potential for deep space missions.
If the module proves durable during two years at the space station, it could open the door to habitats on the moon and missions to Mars, Nasa engineer Glen Miller said.
The agency chose Bigelow for the contract because it was the only company working on inflatable technology, said NASA deputy administrator Lori Garver.

Founder and president Robert Bigelow, who made his fortune in the hotel industry before getting into the space business in 1999, framed the gambit as an out-of-this-world property venture.
He hopes to sell his spare-tire habitats to scientific companies and wealthy adventurers looking for space hotels.
NASA is expected to install the 13ft blimp-like module in a space station port by 2015.
Mr Bigelow plans to begin selling stand-alone space homes the next year.
The new technology provides three times as much room as the existing aluminium models, and is also easier and less costly to build, Mr Miller said.
Artist renderings of the module resemble a tin-foil clown nose grafted on to the main station. It is hardly big enough to be called a room.
Mr Miller described it as a large closet with padded white walls and gear and gizmos strung from two central beams.
When President Obama signed his 23 executive orders this week to reduce gun violence, I had to laugh at several of them. One in particular was to issue a Presidential Memorandum directing the Centers for Disease Control to research the causes and prevention of gun violence.
