Lab-made organ implanted for first time
For the first time, a patient has received a synthetic windpipe that was created in a lab with the patient's own stem cells and without using human donor tissue, researchers said Thursday.
Previous lab-generated transplants either used a segment of donor windpipe or involved tissue only, not an organ.

Japan scientist synthesizes meat from human feces
Somehow this feels like a Vonnegut plotline: population boom equals food shortage. Solution? Synthesize food from human waste matter. Absurd yes, but Japanese scientists have actually discovered a way to create edible steaks from human feces.
Mitsuyuki Ikeda, a researcher from the Okayama Laboratory, has developed steaks based on proteins from human excrement. Tokyo Sewage approached the scientist because of an overabundance of sewage mud. They asked him to explore the possible uses of the sewage and Ikeda found that the mud contained a great deal of protein because of all the bacteria.
The researchers then extracted those proteins, combined them with a reaction enhancer and put it in an exploder which created the artificial steak. The “meat” is 63% proteins, 25% carbohydrates, 3% lipids and 9% minerals. The researchers color the poop meat red with food coloring and enhance the flavor with soy protein. Initial tests have people saying it even tastes like beef.

New graphic cigarette warnings unveiled
The federal government Tuesday unveiled nine graphic images that will be required on all cigarette packs and advertising as part of a powerful new warning strategy.
The images include a picture of a man smoking through a tracheotomy hole in his throat, a horribly diseased lung, mottled teeth and gums, a man breathing with an oxygen mask and a man’s body with a large scar running down the chest. They will be accompanied by messages such as, “Warning: Cigarettes are addictive,” “Warning: Cigarettes cause cancer” and “Warning: Smoking can kill you.”

U.S. Students Remain Poor at History, Tests Show
American students are less proficient in their nation’s history than in any other subject, according to results of a nationwide test released on Tuesday, with most fourth graders unable to say why Abraham Lincoln was an important figure and few high school seniors able to identify China as the North Korean ally that fought American troops during the Korean War.

WHO declares cellphones "possibly carcinogenic"
Those who are worried about the possible health risks of cellphones just received some backing from a significant source: the World Health Organization. A group within the organization, the International Agency for Research on Cancer, has announced it is listing the electromagnetic radiation produced by cell phones as "possibly carcinogenic." The IARC's use of the term "possibly" is key to the decision, as its expert panel determined that the information available is too limited to say anything with a greater degree of certainty, but is sufficient to warrant careful monitoring.

US Pentagon to treat cyber-attacks as 'acts of war'
In future, a US president could consider economic sanctions, cyber-retaliation or a military strike if key US computer systems were attacked, officials have said recently.
The planning was given added urgency by a cyber-attack last month on the defence contractor, Lockheed Martin.
A new report from the Pentagon is due out in a matter of weeks.
"A response to a cyber-incident or attack on the US would not necessarily be a cyber-response. All appropriate options would be on the table," Pentagon spokesman Colonel Dave Lapan told reporters on Tuesday.
Mr Lapan confirmed the Pentagon was drawing up a cyber defence strategy, which would be ready in two to three weeks.
Cyber-attacks from foreign nations that threaten widespread US civilian casualties, like cutting off power supplies or shutting down emergency-responder networks, could be treated as an act of aggression under the new policy.

Largest-Ever Survey of Cosmic History Confirms That Dark Energy Exists, Is Tearing the Universe Apart
After a five-year study of 200,000 galaxies, scientists are more certain than ever that dark energy acts as a repulsive force, tearing the universe apart at an accelerating rate. The research confirms the idea that dark energy dominates gravity throughout the cosmos. But no one has any idea what dark energy actually is or how it works.
