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.

CSN Editor: Recent advances in diagnostics have been truly impressive.

The Science Behind Melting Cheese


Serious Eats: The Science of Melting Cheese

Have you ever gotten all excited to make a grilled cheese and then...your cheese just doesn't melt? Or maybe it breaks, separating into a tough, stringy mass surrounded by a pool of oil? Yup, it's a crappy feeling. Luckily, there are ways to know what you're getting into before that happens. Science ways.

Want to reliably tell whether the cheese you're buying is gonna dominate the melting game or stay nice and solid for cooking or grilling? Wish you could make any melting cheese melt better? Here's what you need to know.

CSN Editor: Damn .... I feel hungry.

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.

My Comment: I always find it amazing that we are still making discoveries even though we have been studying animals .... like killer whales .... for years.

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.

Everything Is CGI



This Is CG -- Techcrunch

This is your semi-regular reminder that CGI is at or beyond the point of absurdity, that everything on the Internet is fake, that there is no spoon, etc.

Because seriously. Look at that. Look at it.

I think this is the first time I’ve watched a video like this and wandered right on past the uncanny valley, only to plummet backwards into it when I realized — about halfway through, mind you — that it was rendered.

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.

Underwater Robots Could Sniff Out Smuggled Drugs, Weapons -- Live Science

A warning to all smugglers: A new underwater robot could be used to sniff out contraband — including weapons and drugs — hidden aboard ships.

Developed by researchers at the Massachusetts Institute of Technology (MIT), the new, oval-shaped robot may be small (it's slightly smaller than a football), but it features some big crime-stopping abilities. One side of the bot is flat, which enables it to slide along the bottom of a ship to perform ultrasound scans of the vessel's hull.

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.

My Comment: For those who love to cook .... a sharp knife is essential. This is a good summary on how to have one.

A Better Map Of The Ocean Floor Has Been Produced

The new gravity data gives us our clearest view yet of the shape of the ocean floor

Satellites Detect 'Thousands' Of New Ocean-Bottom Mountains -- BBC

It is not every day you can announce the discovery of thousands of new mountains on Earth, but that is what a US-European research team has done.

What is more, these peaks are all at least 1.5km high.

The reason they have gone unrecognised until now is because they are at the bottom of the ocean.
Dave Sandwell and colleagues used radar satellites to discern the mountains' presence under water and report their findings in Science Magazine.

My Comment: The oceans are still a mystery .... but more is being discovered about the oceans everyday.

Security Officials: Ebola Pandemic Should Be Treated 'The Same Way' As Threat Posed By Nuclear Weapons


Ebola Virus: Pandemic Should Be Treated 'The Same Way' As Threat Posed By Nuclear Weapons, Security Officials Say -- The Independent

Special report: The Government has admitted that the virus spreading across Africa will 'get worse'

The Ebola virus spreading exponentially across Africa and killing thousands of people “will get worse”, the Government has admitted, amid calls for the full involvement of the international military to contain the disease.

Justine Greening, the International Development Secretary, said that ministers had been shocked by a prediction from the US public health institute that 1.4 million people may be infected by the virus by January if it continues unchecked.

As ministers, diplomats and humanitarian organisations from 20 different countries pledged a further £79 million to control the outbreak, which has already killed more than 3,000 people, a group of 35 European security officials issued a joint declaration suggesting that Ebola should be treated in the same way as the threat posed by nuclear weapons.

UN's Ebola Response Chief Warns Of A 'Global Nightmare' On The Prospect Of The Virus Mutating And Becoming Airborne

A burial team remove a Ebola victim's body from isolation in Sierra Leone

Doomsday Warning: UN Ebola Chief Raises 'Nightmare' Prospect That Virus Could Mutate And Become Airborne - Making It Much More Infectious -- Daily Mail

* UN warns Ebola virus currently plaguing West Africa could become airborne
* The longer it moves between human hosts the greater possibility of mutation
* The risk grows the longer virus is living within the human 'melting pot'
* NGOs have said the Ebola virus is currently infecting five people every hour
* More than 3,300 people have died from Ebola since the outbreak first began
* Officials call for 1,000 new Sierra Leone isolation centres to contain virus
* British survivor says 'horror' of children dying from disease must be avoided
* Will Pooley was first Briton to contract virus after working in Sierra Leone
* Thomas Eric Duncan is the first person to be diagnosed in the U.S.
* He flew into Texas from Liberia, touching down in Brussels and Washington
* Up to 100 people in Texas are feared to have come into contact with him
* Doctors at the hospital in Texas said he was in a serious but stable condition

The longer the Ebola epidemic continues infecting people unabated, the higher the chances it will mutate and become airborne, the UN's Ebola response chief has warned.

Anthony Banbury, the Secretary General's Special Representative, has said there is a 'nightmare' prospect the deadly disease will become airborne if it continues infecting new hosts.

His comments come as organisations battling the crisis in West Africa warned the international community has just four weeks to stop its spread before it spirals 'completely out of control'.

And the British nurse who survived the disease said the 'horror and misery' of watching young children die from the disease must be avoided 'at all costs'.

A New Way To Store Oxygen

Photo: The Oxygen-Absorbing Material. U. of Southern Denmark

Weird Crystal Can Absorb All The Oxygen In A Room -- And Then Release It Later -- Popular Science

This could potentially make fuel cells, space travel, and scuba diving a lot more efficient.

Researchers from the University of Southern Denmark say they’ve invented a crystal that pulls oxygen out of the air and even water. Apparently, just a spoonful of the stuff can suck up all the oxygen in a room.

The crystal is a salt made from cobalt*, and it appears to be capable of holding oxygen at a concentration that is 160 times higher than the air we breathe. The paper notes that "an excess" of the substance would bind up to 99 percent of the oxygen in a room.

But what’s more remarkable is that the crystal can later release the oxygen when exposed to heat or low-oxygen conditions. In a press release, study author Christine McKenzie likens it to the hemoglobin in our blood, which uses iron to bind and release oxygen in the human body.

My Comment: Space travel, underwater use, energy systems/fuel cells, the applications are endless.

A Blast From The Past: A 1981 News Report On The Internet



1981 News Report On The Internet is Now Hilarious -- Neatorama

There are so many amusing things in this 1981 television report about getting newspaper content from the Internet that it's hard to keep track. The smirk and smug tone of voice of the reporter, as if she's informing the public of a quaint yet ridiculous idea that stands no chance of ever being embraced by the public. The opening line: "Imagine if you will, sitting down to your morning coffee and turning on your home computer to read the day's newspaper." Mind boggling! The CRT screens, dial-up connections using a phone receiver and hours of download time for a text file.

The Real Story Of The U.S. President's 'Nuclear Football'

From the Smithsonian National Museum of American History, the nuclear "football." (Jamie Chung)

The Real Story of the "Football" That Follows the President Everywhere -- Michael Dobbs, Smithsonian Magazine

Take a peek at the mysterious black briefcase that has accompanied every U.S. president since John F. Kennedy

It is the closest modern-day equivalent of the medieval crown and scepter—a symbol of supreme authority. Accompanying the commander in chief wherever he goes, the innocuous-looking briefcase is touted in movies and spy novels as the ultimate power accessory, a doomsday machine that could destroy the entire world.

Officially known as the “president’s emergency satchel,” the so-called nuclear “Football”—portable and hand-carried—is built around a sturdy aluminum frame, encased in black leather. A retired Football, emptied of its top-secret inner contents, is currently on display at the Smithsonian National Museum of American History. “We were looking for something that would demonstrate the incredible military power and responsibilities of the president, and we struck upon this iconic object,” says curator Harry Rubenstein.

The Greatest Paper Map Of The United States You’ll Ever See -- Seth Stevenson

Made by one guy in Oregon.

American mapmaking’s most prestigious honor is the “Best of Show” award at the annual competition of the Cartography and Geographic Information Society. The five most recent winners were all maps designed by large, well-known institutions: National Geographic (three times), the Central Intelligence Agency Cartography Center, and the U.S. Census Bureau. But earlier this year, the 38th annual Best of Show award went to a map created by Imus Geographics—which is basically one dude named David Imus working in a farmhouse outside Eugene, Ore.

At first glance, Imus’ “The Essential Geography of the United States of America” may look like any other U.S. wall map. It’s about 4 feet by 3 feet. It uses a standard, two-dimensional conic projection. It has place names. Political boundaries. Lakes, rivers, highways.
