If You Missed The SpaceX Landing, You Can Watch It Here



Popular Science: Missed The SpaceX Landing? Watch It Here

Last night, SpaceX stuck its landing, setting down the first stage of their Falcon 9 rocket after it launched satellites into space.

The move means that it may now be possible to re-use rockets that can transport cargo into orbit. But this particular rocket isn't slated to return to flight. The Verge reports that Elon Musk doesn't want this rocket to fly again because it's the first they've brought back, and is therefore unique. It will be test-fired on the ground, just to see if it could have been reused, then presumably retire to a farm upstate where it can frolic in the meadows. Other rockets that come later will actually be reused across multiple launches (which is kind of the point of re-usable rockets).

These Incredible Maps Reveal The World At A Glance

(Click on Image to Enlarge)
This map shows how large parts of Asia have the smallest penis measurements, between 4.5 inches and 11.4cm, while men in Sudan, the Democratic of Congo and Columbia, amongst others, typically measure between 6.5 inches and 16.5cm in length

Daily Mail: The stunning maps that reveal the world at a glance: From manhood and breast size to obesity and divorce rates, how does YOUR country fare?

* Men in some African and Central American countries have the biggest penis sizes averaging more than 6.5 inches
* Women in Russia have the largest average breast size, with most measuring in at above a D-cup
* The places with the highest levels of obesity were the US and Saudi Arabia when it comes to both men and women

Ever wondered where women with big breasts are abundant and which country has men that are most well-endowed?

These colourful globes map the world's vital statistics but as you have never seen them before.

It seems that some of the stereotypes are true at least with men in many African countries having the biggest penis sizes on average.

Meanwhile, women in Russia have the largest cup-size, with most females measuring in at a D-cup or above.

From which fast-food joint is the most popular in Denmark to which nation keeps the most people incarcerated, some of the results are likely to surprise you.

Why Modern Cars Are So Much Safer



Popular Mechanics: The Physics of Why Modern Cars Are So Much Safer, Explained in 146 Seconds

The science of why you should learn to love the crumple zone.

Car crashes are still extremely deadly—32,719 Americans died in car accidents in 2013, or almost 90 people a day. But the number of people dying in car crashes—particularly when expressed as how many people per 100,000 die in an auto accident—has essentially steadily declined since the early 1970s. the early 1970s.

CSN Editor: The problem with cars that easily "crumple" is that it is easy to damage them at minor speed ... hence higher insurance rates. But it is a still a no brainer .... at moderate to high speeds it is better to be in a a car that crumples than being in a car that does not.

A Look At How Animals Think


Economist: Animals think, therefore…

The inner lives of animals are hard to study. But there is evidence that they may be a lot richer than science once thought

IN 1992, at Tangalooma, off the coast of Queensland, people began to throw fish into the water for the local wild dolphins to eat. In 1998, the dolphins began to feed the humans, throwing fish up onto the jetty for them. The humans thought they were having a bit of fun feeding the animals. What, if anything, did the dolphins think?

Charles Darwin thought the mental capacities of animals and people differed only in degree, not kind—a natural conclusion to reach when armed with the radical new belief that the one evolved from the other. His last great book, “The Expression of Emotions in Man and Animals”, examined joy, love and grief in birds, domestic animals and primates as well as in various human races. But Darwin’s attitude to animals—easily shared by people in everyday contact with dogs, horses, even mice—ran contrary to a long tradition in European thought which held that animals had no minds at all. This way of thinking stemmed from the argument of RenĂ© Descartes, a great 17th-century philosopher, that people were creatures of reason, linked to the mind of God, while animals were merely machines made of flesh—living robots which, in the words of Nicolas Malebranche, one of his followers, “eat without pleasure, cry without pain, grow without knowing it: they desire nothing, fear nothing, know nothing.”

Is There A Safe Level Of Alcohol Consumption?

Photo courtesy of www.somethingyoushouldread.com

The Guardian: There is no such thing as a safe level of alcohol consumption

The idea that drinking small amounts of alcohol will do you no harm is a myth, claims Professor David Nutt

Last week I attended a discussion group chaired by the Observer's health correspondent Denis Campbell where one of the other experts, a public health doctor, asserted that alcohol should be treated differently from tobacco (and by inference other drugs) because there is no safe dose of tobacco whereas alcohol is safe until a person's drinking gets to "unsafe" levels. Its health benefits for the cardiovascular system are also often used to support the claim that in low doses alcohol is safe, for how else could it be health-promoting?

The myth of a safe level of drinking is a powerful claim. It is one that many health professionals appear to believe in and that the alcohol industry uses to defend its strategy of making the drug readily available at low prices. However, the claim is wrong and the supporting evidence flawed.

There is no safe dose of alcohol for these reasons:

Glitches Prevent Users From Using Skype



Daily Mail: Skype goes offline: Glitch prevents users from making calls and logging in

* Skype says glitch makes users appear to be offline even if they are online
* The technical problem is thought to be affecting users around the world
* Microsoft, which owns Skype, said engineers were working to fix the issue

Skype users around the world have been left unable to make calls with service after a glitch made everyone appear as if they were offline.

Microsoft, which owns Skype, said the technical problem meant users signed into were unable to change their status and all contacts showed as offline even if they were online.

This meant users were unable to initiate calls to each other.

CSN editor: I needed Skype today .... but in the end I had to make a long distance phone call. Yup .... you never appreciate the tech that we have until we no longer have it.

Popular Science: Your History In A Drop Of Blood

A new test can see just about every virus you've ever had

A blood sample can now reveal a record of viruses you’ve had throughout life, thanks to a new test developed at Harvard called VirScan. It looks for evidence of antibodies produced by the immune system to kill viral invaders. “It’s kind of like fishing,” says geneticist Tomasz Kula. “We’ve made this huge pond [of viral bits], and we see which ones the antibodies stick to.”

How it works: VirScan matches antibodies in a person’s blood sample to a library of 93,000 snippets of viral code. It can find evidence of up to 1,000 different viruses.

Here are the viruses the team found in 303 blood samples--hover over the yellow circles to learn more.

This Is What One Year In Space Does To Your Body



The Verge: Here’s what one year in space does to your body

Want to know how much poop an astronaut produces while spending a year on the International Space Station? It's somewhere around 180 pounds.

That fun fact is brought to you by NASA, which just released an infographic breaking down all the numbers surrounding astronaut Scott Kelly's one-year stay on the ISS. Kelly and cosmonaut Mikhail Kornienko are both in the midst of spending a full year on the station as part of the One Year Mission — an experiment to study the long-term effects of spaceflight on the human body. The mission will help NASA better prepare for its eventual journey to Mars in the 2030s. A trip to the Red Planet is going to take multiple months, so NASA wants to know how the microgravity environment of space will affect the body during that time.

CSN Editor: One year in space .... that is a long time.

Killer Whales Can 'Talk' Like Dolphins



Killer Whales Can 'Talk' Like Dolphins When The Two Species Spend Time Together: Orcas Imitate Sounds To Help Them Communicate -- Daily Mail

* Killer whales can engage in cross-species ‘vocal learning’ by matching the types of sounds made by bottlenose dolphins when spending time with them
* Results suggest vocal imitation may enable social interactions in cetaceans
* Killer whales make clicks, whistles and pulsed calls, which are repeated brief bursts of sound punctuated with silence
* When they spent time with dolphins they altered these noises to make more dolphin-like clicks and fewer pulsed calls, which dolphins don't make
* Study was conducted by Hubbs-SeaWorld Research Institute in San Diego

Most animals make noises that are innate, not learned.

But scientists claim killer whales can learn to ‘talk’ like dolphins when the two species spend time together.

This means the ocean predators join the likes of bats, some birds and humans that each copy sounds and use them in appropriate social contexts.

A Means To Harness Wind Energy At 2,000 Feet

Altaeros' Buoyant Air Turbine: Last year, Altaeros tested a prototype of the turbine at a height of 500 feet in Maine, where it flew in 45mph winds. courtesy Altaeros

The Quest To Harness Wind Energy At 2,000 Feet -- Popular Science

High-altitude wind contains enough energy to power the planet. A Boston start-up wants to be the first to bring it down to Earth.

Nothing about the grooved, inflatable body taking shape inside Greentown Labs in Somerville, Massachusetts, resembles a wind turbine. It looks more like a jetliner's emergency ramp, or something you'd tie behind a boat and cling to desperately while bumping across the surface of a lake. But the 14-foot-long structure most resembles what it actually is--an air-filled wing.

To be more precise, it's a stabilizing fin, part of a tube-shaped, robotic airship designed to tap the power of high-altitude winds. The blade tips of today's tallest conventional wind turbine, installed at a test center in Denmark this year, stretch to 720 feet. The fully autonomous, lighter-than-air BAT (short for buoyant airborne turbine) will climb as high as 2,000 feet, where winds blow stronger and steadier.

My Comment: People are protesting windmills on the ground .... I expect the same protests for these wind turbines 2,000 feet in the air.

Spain Has Outbreak's 1st Known Case Of Contracting Ebola Outside Of Africa -- CNN

(CNN) -- A nurse's assistant in Spain is the first person known to have contracted Ebola outside of Africa in the current outbreak.

Spanish Health Minister Ana Mato announced Monday that a test confirmed the assistant has the virus.

The woman had helped treat a Spanish missionary and a Spanish priest, both of whom had contracted Ebola in West Africa.

Both died after returning to Spain.

Health officials said she developed symptoms on September 30. She was hospitalized Sunday.

An investigation is under way to find everyone she may have had contact with while contagious. So far, there are no other known cases.

She was one of about 30 health professionals in Spain who helped to treat the Ebola patients.

You Can Now Make A Metal Gun In Your Home



The $1,200 Machine That Lets Anyone Make a Metal Gun at Home -- Threat Level/Wired

When Cody Wilson revealed the world’s first fully 3-D printed gun last year, he showed that the “maker” movement has enabled anyone to create a working, lethal firearm with a click in the privacy of his or her garage. Now he’s moved on to a new form of digital DIY gunsmithing. And this time the results aren’t made of plastic.

Wilson’s latest radically libertarian project is a PC-connected milling machine he calls the Ghost Gunner. Like any computer-numerically-controlled (or CNC) mill, the one-foot-cubed black box uses a drill bit mounted on a head that moves in three dimensions to automatically carve digitally-modeled shapes into polymer, wood or aluminum. But this CNC mill, sold by Wilson’s organization known as Defense Distributed for $1,200, is designed to create one object in particular: the component of an AR-15 rifle known as its lower receiver.

The Science Of Sharpening A Knife



How To Sharpen Any Knife -- Gizmodo

A sharp knife isn't just sharper, it's a safer, more efficient, more precise tool. And, like most people, your knives are probably dull. Here's how to fix that quickly, easily and cheaply.

Why do you need to sharpen knives? A sharp knife stands less chance of slipping on the material being cut and, because it requires less effort and force to use than a dull knife, you're less likely to cut yourself. Working with a sharp knife is faster and easier, too. It also damages the material being cut less — ever tried to slice a tomato with a dull knife? It doesn't exactly produce clean results.
