Swine Flu Speranta

Although in the early stages of the swine flu pandemic there were worries that humans would catch the virus from pigs, this has so far not been documented and pigs and other animals have not been involved in the current spread of A/H1N1 influenza in humans,"

“As far as we know, no other research group has used machine learning to teach a robot to make realistic facial expressions,” said Tingfan Wu, the computer science Ph.D. student from the UC San Diego Jacobs School of Engineering who presented this advance on June 6 at the IEEE International Conference on Development and Learning.

said Dr Vahlenkamp, "However, with the increasing numbers of human infections, a spill over of this human virus to pigs is becoming more likely. The prevention of human-to-pig transmissions should have a high priority in order to avoid involvement of pigs in the epidemiology of this pandemic

The shapes and measurements of brain structures can reveal how they function. Thus, Csernansky hopes his brain maps will reveal how the brains of humans with and without major mental disorders differ from each other and the time frame over which those differences develop.

Facial expressions do not actually involve the entire face, but rather specific sets of muscles under the face near the eyes, nose and mouth. Bhattacharya and Sohail's system measures 15 key points on the face and then compares these measures against images of identifiable facial expressions. Although there is great variety in expression across both individuals and cultures, the pair has identified seven basic expressions that seem to be relatively universal.

Coordination across federal agencies, combined with a competent technical work force, effective infrastructure, and investment in technology and innovation, would lay the foundation for a purposeful, strategic U.S. space program that would serve national interests.

The maneuver to change Odyssey's orbit began Sept. 30, 2008, and ended June 9, 2009, with a five-and-a-half-minute thruster firing. The rocket burn fixed the spacecraft's track so that THEMIS looks down on the planet at an earlier time of day, 3:45 in the afternoon instead of 5 p.m.

IBEX is the latest in NASA's series of low-cost, rapidly developed Small Explorers spacecraft. The IBEX mission was developed by SwRI with a national and international team of partners. NASA's Goddard Space Flight Center manages the Explorers Program for NASA's Science Mission Directorate.

also links a lot of useful 8008 resources for anyone wanting to tackle a project of their own.

Right now, the cells are used commercially to recharge cell phones. It would take a lot more of them to charge an unmanned aerial vehicle (UAV), but ll good Geeks you should be able to utilize resources to accomplish any of these things the military thinks the project is feasible. Mostly because dye-sensitized cells are cheap and small compared to the silicon alternative. They’re a little less efficient, but cost a quarter as much to produce. And the cells are lightweight and thin, so they could spread across the wings of an UAV

Astronomers from the National Astronomical Observatory of Japan (NAOJ), from London, Manchester and Kent universities in the UK and from a university in Missouri in the USA studied the emissions from hydrogen molecules in the infrared and found that knots are found throughout the entire nebula. Although these molecules are often destroyed by ultraviolet radiation in space, they have survived in these knots, shielded by dust and gas that can be seen in optical images. The comet-like shape of these knots results from the steady evaporation of gas from the knots, produced by the strong winds and

The IBEX team estimates that only about 10 percent of the solar wind ions reflect off the sunward side of the moon as neutral atoms, while the remaining 90 percent are embedded in the lunar surface. Characteristics of the lunar surface, such as dust, craters and rocks, play a role in determining the percentage of particles that become embedded and the percentage of neutral particles, as well as their direction of travel, that scatter.

Antimatter Positrons Illuminate

By creating robust simulations of the early universe, astrophysicists Matthew Turk and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, located at the Department of Energy’s SLAC National Accelerator Laboratory, and Brian O'Shea of Michigan State University have gained the most detailed understanding to date of the formation of the first stars.

In two separate scientific papers, the most recent of which appears in the July 10 issue of the journal Physical Review Letters, the astrophysicists show that this distribution of gamma rays can be explained by the way antimatter positrons from the radioactive decay of elements, created by massive star explosions in the galaxy, propagate through the galaxy. Thus, the scientists said, the observed distribution of gamma rays is not evidence for dark matter.

Turk, Abel and O'Shea ran five data-intensive simulations, each of which covered a 400 quadrillion cubic mile volume of the universe and took about three weeks to run on 64 processors. The simulations focused on the first Population III stars: massive, hot stars thought to have formed a mere several hundred million years after the Big Bang.

What is known for certain is that our galaxy—and others—are filled with tiny subatomic particles known as positrons, the antimatter counterpart of typical, everyday electrons. When an electron and positron encounter each other in space, the two particles annihilate and their energy is released as gamma rays. That is, the electron and positron disappear and two or three gamma rays appear speranta.
