How To Make Antivenom

 

 

Published on May 16, 2013

” Bitten by a venomous snake? There’s hope! French scientist Albert Calmette developed the first snake antivenom in the late 1890s, and did such a good job that we use his technique to this day. Antivenom works by stimulating the production of antibodies which can smother venom’s toxic effects, preventing spread and rendering them harmless. But how do you make it? Well, stay tuned to this episode of SciShow to find out.

Men Who Are Physically Strong Are More Likely To Have Right Wing Political Views

 

 

Right Wing

 

” Men who are physically strong are more likely to take a right wing political stance, while weaker men are inclined to support the welfare state, according to a new study.

Researchers discovered political motivations may have evolutionary links to physical strength.

Men’s upper-body strength predicts their political opinions on economic redistribution, according to the research.

The principal investigators – psychological scientists Michael Bang Petersen, of Aarhus University in Denmark, and Daniel Sznycer, of the University of California in the U.S., believe that the link may reflect psychological traits that evolved in response to our early ancestral environments and continue to influence behaviour today.

Professor Petersen said: ‘While many think of politics as a modern phenomenon, it has – in a sense – always been with our species.’

In the days of our early ancestors, decisions about the distribution of resources were not made in courthouses or legislative offices, but through shows of strength.

  • Weaker men more likely to support welfare state and wealth redistribution
  • Link may reflect psychological traits that evolved in our ancestors
  • Strength was a proxy for ability to defend or acquire resources
  • There is no link between women’s physical strength and political views”

Nikola Tesla’s Lab Saved Through Crowd-Sourcing

 

 

 

” In 9 days, we managed to raise over 1 million dollars to go towards buying back Tesla’s old laboratory, and with the $850,000 matching grant from NY state this puts us at 1.85 million bucks. At its peak, the campaign was raising $27,000 per hour, crashing Indiegogo, and probably setting some kind of land speed record in awesomeness. Indiegogo put together this infographic showing some interesting data points behind the campaign.

We’ve added some new perks to the campaign, including more t-shirts, hats, and posters signed by Tesla’s last remaining relative.”

Hanging Gardens Existed, But Not In Babylon

 

 

” Mythology shrouds each of the Seven Wonders of the Ancient World, but none has been more mysterious than the Hanging Gardens of Babylon. Archaeologists have never unearthed evidence of the soaring gardens, and scholars have questioned its very existence. Now, however, an Oxford University researcher says she knows why the Hanging Gardens of Babylon have proven so elusive. It’s because they weren’t in Babylon at all.

Babylonian king Nebuchadnezzar II was said to have constructed the luxurious Hanging Gardens in the sixth century B.C. as a gift to his wife, Amytis, who was homesick for the beautiful vegetation and mountains of her native Media (the northwestern part of modern-day Iran). To make the desert bloom, a marvel of irrigation engineering would have been required. Scientists have surmised that a system of pumps, waterwheels and cisterns would have been employed to raise and deliver the water from the nearby Euphrates River to the top of the gardens.

However, Dr. Stephanie Dalley, an honorary research fellow and part of the Oriental Institute at England’s Oxford University, believes she has found evidence of the existence of the legendary Wonder of the Ancient World. In her soon-to-be-released book “The Mystery of the Hanging Garden of Babylon: An Elusive World Wonder Traced,” published by Oxford University Press, Dalley asserts that the reason why no traces of the Hanging Gardens have ever been found in Babylon is because they were never built there in the first place.”

3D Printing Is Way Scarier Than Plastic Guns

 

 

 

 

 

” Ever the publicity hound, Sen. Chuck Schumer, who obviously has no idea what additive manufacturing actually is, came out big and strong against “stomach-churning” 3D printed plastic guns last week.

This naive, sensationalist rant so misunderstands the issue, I almost don’t know where to start.  He goes on to inform the public that because these guns are made of plastic, they are undetectable, so he must introduce legislation that will make it illegal to possess an undetectable or an untraceable weapon.  This is like putting a “Band-Aid on a heart attack.”  Sen. Schumer simply doesn’t understand what he is dealing with.  In fact, most of us don’t.

Now that you know what a 3D printer is, you must also understand that 3D printers are not limited to printing in plastic.  There are 3D printers that print in wood (a mixture of wood particles and binding agent that dries as wood) ceramic, carbon fiber, bronze, iron, steel, cellulose, human tissue (certain body parts for human transplant are grown using 3D printed frameworks) … there are limitations to the range of additive manufacturing materials, but the technology is evolving rapidly.

As for guns … CAD/CAM files (the computer files that 3D printers transform into physical objects one layer at a time) for the .45 caliber M1911 or the 1911A-1 single-action, semi-automatic pistol have been online for years.  In fact, you can find all kinds of CAD/CAMs for all kinds of gun parts, bomb parts, bazooka parts, rocket launcher parts and other deadly weapons online.  These are computer files, like songs or movies or documents or images, they cannot be protected or digitally rights managed (DRM) any better than the entertainment industry has done with its intellectual property.  A file is a file is a file, if someone wants to copy it – it will be copied.  You can’t tell what the file contains unless you open it and, most importantly, there is no way to ban or prohibit the transfer of files.  In this case, the genie is out of the bottle, you can’t put the toothpaste back in the tube, the ship has sailed – the files are out there.

Plastic guns?  Seriously.  How about guns printed in steel, guns printed in carbon fiber, guns printed in, you name it – there’s a 3D printer that can print in the medium.  In a world of 3D printers, there is no such thing as gun control – people who are so inclined will print all the guns and ammo they need – untraceable, no serial numbers, no markings about point of origin, no trade marks, nothing! “

FBI’s Latest Proposal For A Wiretap-Ready Internet Should Be Trashed

 

 

 

” The FBI has some strange ideas about how to “update” federal surveillance laws: They’re calling for legislation to penalize online services that provide users with too much security.

I’m not kidding. The proposal was revealed in The Washington Post last week — and a couple days ago, a front-page story in The New York Times reported the Obama administration is preparing to back it.

Why? Federal law enforcement agencies like the FBI have long feared their wiretap capabilities would begin “going dark” as criminals and terrorists — along with ordinary citizens — shift from telephone networks, which are required to be wiretap-ready under the 1994 Communications Assistance for Law Enforcement Act (CALEA), to the dizzying array of online communications platforms available today.”

 

 

 

 

 

 

 

 

Lamborghini Egoista Concept Car A ‘Four-Wheeled UFO’

 

 

 

 

” Lamborghini Egoista, inspired by the design of an Apache helicopter, was introduced to the world over the weekend. While the Lamborghini Egoista is a pure design concept, Lamborghini has said in the past that it never builds a concept without the intention of production. “

 

 

” Over the weekend, the first photos and details for a brand new Lamborghini concept cropped up. We now have all the official details for the concept, which goes by the name “Egoista” and was developed as a tribute to Lamborghini’s 50th anniversary by a team led by Volkswagen Group design boss Walter De Silva.”

 

 

 

 

 

 

 

 

Terrafugia TF-X: The Vertical Take-Off Flying Car

 

 

 

 

” Terrafugia, the Woburn, MA, company developing the Transition flying car, has plans for a vertical take-off and landing (VTOL) sibling. The proposed Terrafugia TF-X would be a tilt-rotor flying machine that would take off and land like a helicopter. Instead of a runway, the TF-X could use a helipad or parking lot. That’s important because Terrafugia’s devices aren’t so much flying cars as roadable aircraft that take you from the airport to your destination a few miles away. The closer you land to your destination, the better. Don’t sell your Cessna 400 just yet. The TF-X is a decade away and will likely cost on the high side of a half-million dollars. Maybe a million.”

 

 

 

 

 

 

 

 

 

Byzantine Mosaic Unearthed In Southern Israel

Top U.S. Admiral Puts Cyber Security On The Navy’s Radar

 

 

 

 

” Cyber security and warfare are on par with a credible nuclear deterrent in the defense priorities of the United States, the U.S. Navy’s top admiral said on Monday, after the Pentagon accused China of trying to hack into its computer networks.

Admiral Jonathan Greenert, the chief of naval operations, told Reuters the defense department’s cyber program had continued unabated despite the political gridlock about the U.S. budget deficit and enforced spending cuts in other areas.

“The level of investment that we put into cyber in the department is as protected or as focused as it would be in strategic nuclear,” Greenert said in an interview in Singapore just before the start of the three-day Reuters Cybersecurity Summit in Washington (link.reuters.com/dam97t).”

 

 

 

 

 

 

 

Flying Car Crashes In Canada

 

 

 

 

” A “flying car” crashed today in British Columbia, Canada.

The Globe and Mail reports that the vehicle, which operates like a paraplane and looks like a hotrod with a propeller on the back, suffered a malfunction during takeoff and crash landed at a school near the Vernon airport. Authorities say it was the first incident of its kind in Canada.

The pilot and passenger suffered injuries, but are both expected to recover according to the local police. No one was on the ground at the time of the accident.

The vehicle is built in Florida and called the Maverick. It uses a four-cylinder Subaru engine to power either the propeller or the wheels, and can be used on or off road at speeds up to 100 mph on the ground. A deployable parachute allows it to take off and land from a football field length runway.”

State Department Demands Takedown Of 3D-Printable Gun Files For Possible Export Control Violations

 

 

 

” The battle for control of dangerous digital shapes may have just begun.

On Thursday, Defense Distributed founder Cody Wilson received a letter from the State Department Office of Defense Trade Controls Compliance demanding that he take down the online blueprints for the 3D-printable “Liberator” handgun that his group released Monday, along with nine other 3D-printable firearms components hosted on the group’s website Defcad.org. The government says it wants to review the files for compliance with arms export control laws known as the International Traffic in Arms Regulations, or ITAR. By uploading the weapons files to the Internet and allowing them to be downloaded abroad, the letter implies Wilson’s high-tech gun group may have violated those export controls

Despite taking down his files, Wilson doesn’t see the government’s attempts to censor the Liberator’s blueprints as a defeat. On the contrary, Defense Distributed’s radical libertarian and anarchist founder says he’s been seeking to highlight exactly this issue, that a 3D-printable gun can’t be stopped from spreading around the global Internet no matter what legal measures governments take. “This is the conversation I want,” Wilson says. “Is this a workable regulatory regime? Can there be defense trade control in the era of the Internet and 3D printing?”

Wilson compares his new legal troubles to the widely-followed case in the mid-1990s of Philip Zimmermann, the inventor of the cryptographic software PGP, who was threatened with indictment under ITAR for putting his military-grade encryption software online. “It’s PGP all over again,” says Wilson.

 

 

Here is the letter Mr Wilson received from the State department ;

 

” In reply letter to DTCC Case: 13-0001444

[Cody Wilson's address redacted]

Dear Mr. Wilson,

The Department of State, Bureau of Political Military Affairs, Office of Defense Trade Controls Compliance, Enforcement Division (DTCC/END) is responsible for compliance with and civil enforcement of the Arms Export Control Act (22 U.S.C. 2778) (AECA) and the AECA’s implementing regulations, the International Traffic in Arms Regulations (22 C.F.R. Parts 120-130) (ITAR). The AECA and the ITAR impose certain requirements and restrictions on the transfer of, and access to, controlled defense articles and related technical data designated by the United States Munitions List (USML) (22 C.F.R. Part 121).

The DTCC/END is conducting a review of technical data made publicly available by Defense Distributed through its 3D printing website, DEFCAD.org, the majority of which appear to be related to items in Category I of the USML. Defense Distributed may have released ITAR-controlled technical data without the required prior authorization from the Directorate of Defense Trade Controls (DDTC), a violation of the ITAR.

Technical data regulated under the ITAR refers to information required for the design, development, production, manufacture, assembly, operation, repair, testing, maintenance or modification of defense articles, including information in the form of blueprints, drawings, photographs, plans, instructions or documentation. For a complete definition of technical data, see 120.10 of the ITAR. Pursuant to 127.1 of the ITAR, it is unlawful to export any defense article or technical data for which a license or written approval is required without first obtaining the required authorization from the DDTC. Please note that disclosing (including oral or visual disclosure) or tranferring technical data to a foreign person, whether in the United States or abroad, is considered an export under 120.17 of the ITAR.

The Department believes Defense Distributed may not have established the proper jurisdiction of the subject technical data. To resolve this matter officially, we request that Defense Distributed submit Commodity Jurisdiction (CJ) determination requests for the following selection of data files available on DEFCAD.org, and any other technical data for which Defense Distributed is unable to determine proper jurisdiction:

  1. Defense Distributed Liberator pistol
  2. .22 electric
  3. 125mm BK-14M high-explosive anti-tank warhead
  4. 5.56/.223 muzzle brake
  5. Springfield XD-40 tactical slide assembly
  6. Sound Moderator – slip on
  7. “The Dirty Diane” 1/2-28 to 3/4-16 STP S3600 oil filter silencer adapter
  8. 12 gauge to .22 CB sub-caliber insert
  9. Voltlock electronic black powder system
  10. VZ-58 sight

DTCC/END requests that Defense Distributed submits its CJ requests within three weeks of the receipt of this letter and notify this office of the final CJ determinations. All CJ requests must be submitted electronically through an online application using the DS-4076 Commodity Jurisdiction Request Form. The form, guidance for submitting CJ requests, and other relevant information such as a copy of the ITAR can be found on DDTC’s website at http://www.pmddtc.state.gov.

Until the Department provides Defense Distributed with the final CJ determinations, Defense Distributed should treat the above technical data as ITAR-controlled. This means that all such data should be removed from public access immediately. Defense Distributed should also review the remainder of the data made public on its website to determine whether any additional data may be similarly controlled and proceed according to ITAR requirements.

Additionally, DTCC/END requests information about the procedures Defense Distributed follows to determine the classification of its technical data, to include aforementioned technical data files. We ask that you provide your procedures for determining proper jurisdiction of technical data within 30 days of the date of this letter to Ms. Bridget Van Buren, Compliance Specialist, Enforcement Division, at the address below.

Blueprints For 3D-Plastic Gun Downloaded 100,000 Times In 2 Days Before The State Department Orders The Site To Take Down The Weapon Designs

Crude: The Liberator plastic gun is a simple single-shot weapon that fires a small .380-caliber bullet

” Blueprints for the first-ever plastic gun produced on a 3-D printer, that can pass through metal detectors, have been downloaded over 100,000 times since it was posted to the web on Monday. 

Designs for the ‘Liberator’ pistol were posted online by Defense Distributed but on Thursday the U.S. State Department ordered the website to take down the blueprints, on the basis that the plans could violate export regulations. “

” The blueprints, that could be produced on 3-D printers costing as little as $1,000, were seen as a breakthrough because no one has previously designed such a weapon that could withstand the pressure of firing modern ammunition.

Surprisingly, most downloads of the plans did not come from inside the U.S. but from Spain.

The U.S. is second, ahead of Brazil, Germany, and the U.K., according to Haroon Khalid, a developer working with Defense Distributed, who reported the statistics to Forbes.”

Ancient Arctic Was Warm, Wet, And Green. What That Says About The Future.

 

 

 

” Working with a continuous record of Arctic climate reaching back 3.6 million years, researchers have documented a period when the region was significantly warmer and wetter than it is today and when the atmosphere’s inventory of carbon dioxide was comparable to today’s levels.

The period the team has analyzed covers the first 1.4 million years of the record, when the region’s climate shifted from warm and wet to conditions that signaled the start of ice ages.

This period is of interest in part because the warmth persisted despite periodic shifts in Earth’s orbit that reduced the intensity of sunlight reaching the region.

The evidence is captured in a 1,034-foot core sample the team drew from the bottom of Lake El’gygytgyn, known informally as Lake E. It formed 3.6 billion years ago after a meteor punched a crater in Russia’s northeastern Arctic. The crater filled to form a lake 7 miles across and some 560 feet deep. The area around the lake managed to remain ice free during the ebb and flow of continental ice sheets during the Pleistocene ice ages, allowing sediment layers – and the pollen and other climate indicators they contain – to build up uninterrupted for the last 3.56 million years.”

 

 

 

 

 

Unique Animals Found At East Coast Methane Seep

 

Collecting animals

 

” While surveying the seafloor last fall, a research vessel spotted bubbles rising from the depths.

Now, another ship has gone back to investigate, and found a variety of life on the seafloor surrounding a methane seep, according to an update from researchers with the National Oceanic and Atmospheric Administration (NOAA).

On May 8, the NOAA ship Ron Brown deployed an unmanned sub named Jason to the seafloor offshore Virginia. The sub came upon patches of white bacteria that can harness energy by breaking down methane and are a dead giveaway that leaking natural gas is likely to be found nearby. It encountered the seep at a depth of 1 mile (1.6 kilometers), the vehicle’s deepest dive. 

The submarine snapped photos of a spider crab and other unidentified fish surrounding the methane seep. The vehicle also took samples of soil and live mussels that scientists will later analyze in order to better understand life from the abyss.

SpaceX Joining Virgin Galactic At Spaceport America

 

 

 

 

” New Mexico Governor Susana Martinez announced on Tuesday that SpaceX has signed a three-year agreement to use Spaceport America for flight testing.

According to a Spaceport America statement, SpaceX will be leasing land and facilities at the New Mexico site to conduct the next phase of flight testing for its reusable rocket program.

“I am thrilled that SpaceX has chosen to make New Mexico its home, bringing their revolutionary ‘Grasshopper’ rocket and new jobs with them,” Governor Martinez said today. “We’ve done a lot of work to level the playing field so we can compete in the space industry. This is just the first step in broadening the base out at the Spaceport and securing even more tenants. I’m proud to welcome SpaceX to New Mexico.”

SpaceX just finished up its first series of testing the new Grasshopper vehicle in McGregor, Texas. The company is planning to begin the next phase of development for tests performed in New Mexico.”

 

 

 

 

 

 

 

 

How The New Bay Bridge Shakes Off A Quake

 

 

” Earthquake-prone California is a far from ideal place to string metal over water and hope it stays put. But engineers of the new eastern span of the San Francisco–­Oakland Bay Bridge say the structure should last at least 150 years. This fall, when the new portion opens, the Bay Bridge will stretch 2047 feet, becoming the world’s longest self-anchored suspension bridge. 

Unlike a conventional suspension bridge, in which cables anchor on shore, the Bay Bridge can’t rely on the surrounding muddy ground—which amplifies seismic movement—for support. So the bridge is anchored to itself, with a single cable looping around the roadway and held high by a steel tower. ”

OBAMA SPENT $11.45 MILLION PER ‘GREEN JOB’ CREATED

 

 

” In 2008, then-candidate Barack Obama promised to create 5 million “green jobs” if elected president. However, an analysis by the Institute for Energy Research (IER) finds that since 2009, the Department of Energy’s (DOE) $26 billion loan program created just 2,298 permanent jobs, at a cost of $11.45 million per job created.

In his New York Times bestselling book Throw Them All Out, Government Accountability Institute President Peter Schweizer revealed that 80% of Department of Energy loans went to companies owned by or connected to President Barack Obama’s top campaign fundraisers.”

 

 

 

 

 

 

 

” Another day, another monster? Not quite, this time. A large aquatic animal, apparently carnivorous, has washed up in New Zealand. The body is badly decomposed, and suggests a crocodilian head with a twin fin tail.

 
Sydney Morning Herald article suggestions so far contain just about everything:

 

A marine mammal expert from the Museum of New Zealand, Anton van Helden, told NZ media that based on the creature’s fins, it was most likely to be a killer whale. The body had probably been floating around at sea for some time before it washed up, he said.

 

The orca suggestion isn’t quite so far fetched, despite the apparent crocodilian resemblance. Orca teeth are similarly structured, and hooked. Information from the Orca Project shows distinctly similar teeth.”
