Last week, on the first day of the government shutdown, I flew a trip in the IFR system and everything was totally normal. So far controllers and FSS are still on the job and the system is working, but other vital general aviation activities are far from normal. Airplane registrations have been suspended so buying and selling existing airplanes, and delivery of new airplanes, is grinding to a halt. Though it is still legal to transfer ownership of an airplane, it has become practically speaking impossible. Without the FAA aircraft registration staff working ownership transfer paperwork is on hold. Title searches for the sale of an airplane can’t be conducted so lenders will balk. ...

These days, it is far too easy to rattle off the outrageous examples of zero tolerance policy run amok in our nation’s schools. A 14-year-old student arrested for texting in class. Three middle school aged boys in Florida thrown to the ground by police officers wielding rifles, who then arrested them for goofing off on the roof of the school. A 9-year-old boy suspended for allegedly pointing a toy at a classmate and saying “bang, bang.” Two 6-year-old students in Maryland suspended for using their fingers as imaginary guns in a schoolyard game of cops and robbers. A 17-year-old charged with a felony for keeping his tackle box in his car parked on school property, potentially ...

WASHINGTON, Oct. 7 (Xinhua) -- U.S. researchers said Monday they have devised a three dimensional (3D) microscopic printing technique to study how communities of bacteria, such as those in the human gut and lungs, interact and influence human health. Bacteria in the human body often thrive within structured 3D communities that contain multiple bacterial species. Recent studies have found that relationships between structure and function in these microbial ecosystems can affect human health, such as the virulence of infections in chronic wounds. To help study these relationships, researchers from the University of Texas developed a laser-based printing technology to build protein ...

China last week conducted a test of a maneuvering satellite that captured another satellite in space during what Pentagon officials say was a significant step forward for Beijing’s space warfare program. The satellite capture took place last week and involved one of three small satellites fitted with a mechanical arm that were launched July 20 as part of a covert anti-satellite weapons development program, said U.S. officials familiar with reports of the test. One official described the satellite-grabbing spacecraft as a “mobile satellite launch vehicle.” A Pentagon spokeswoman declined to comment on the specifics of the test. But Cynthia O. Smith, the spokeswoman, ...

Envision biting into a warm juicy burger with all the trimmings. If you are a burger fan, your mouth may already be watering. If you are a vegetarian or animal welfare advocate, however, you might be rather disturbed by this imagery. Now imagine that as you are still chewing a bite of that same burger the server tells you that this beef burger was grown in a plastic dish in a stem cell lab. No cow involved! Would you have a beef with such a bioengineered burger? Or celebrate the fact that no cow lost its life to make this burger? Can we even call this test tube meet “beef” and would a vegetarian eat it? We had better start thinking about such questions because laboratory ...

ScienceDaily: Sep. 30, 2013 — Naked mole rats have what any animal would want. They live long lives -- about 30 years -- and stay healthy until the very end. Now biologists at the University of Rochester have new insights into the animal's longevity -- better-constructed proteins. Proteins are involved in nearly all functions of an animal cell, and consequently, are essential to all organisms. But before proteins can do their job, they must fold into the appropriate shapes that allow them to connect to and interact with other structures in the cell. In a paper published this week in the Proceedings of the National Academy of Sciences, Vera Gorbunova and Andrei Seluanov describe ...

Science Daily Sep. 30, 2013 — NASA's Cassini spacecraft has detected propylene, a chemical used to make food-storage containers, car bumpers and other consumer products, on Saturn's moon Titan. This is the first definitive detection of the plastic ingredient on any moon or planet, other than Earth. A small amount of propylene was identified in Titan's lower atmosphere by Cassini's Composite Infrared Spectrometer (CIRS). This instrument measures the infrared light, or heat radiation, emitted from Saturn and its moons in much the same way our hands feel the warmth of a fire. Propylene is the first molecule to be discovered on Titan using CIRS. By isolating the same ...

Tetsuro Matsuzawa begins his working day, conventionally enough, in front of a computer. He taps in a few commands, takes a seat and waits. Within minutes, the calm of his basement laboratory is pierced by the sound of excitable primates. On cue, two chimpanzees appear through an opening in the ceiling, flash a look of recognition at Matsuzawa, and then aim an inquisitive stare at his unfamiliar companion from the Observer. Matsuzawa feeds them a spoonful of honey each and wipes their hands and fingers – a near-daily ritual meant to reward them for arriving on time, and to encourage them to show up again the following morning. After all, Ai, a 36-year-old chimpanzee, and her ...
