Each and every one of us human beings has a story, a past, a present, and a future that is all wrapped up in our belief systems and how those belief systems affect our daily lives. What we believe comes from our educational background, the upbringing and training we had from our families, our ethnic and cultural influences, and research we have each independently done plus our life experiences. How we identify who we are, what we are, and why we are here is aligned with what we know or feel or understand to be truths according to our experiences and education thus far in life. What we believe about who we are in large part determines how we view our purpose in life. Our purpose in life provides our motivation and our blueprint for the decisions we make, the way we treat others, and the way we live our lives.

Psychologists have used implantable electrodes and a first-person driving game to identify the cells of the brain that indicate travel in a clockwise or counterclockwise motion, called "path cells."

Scientists and surgeons have led a revolutionary operation to transplant a new trachea into a child, using the child's own stem cells to rebuild the airway in the body.

Controlling x-rays with ultrashort slices of light is a step toward controlling how matter behaves, shaping x-rays with other x-rays, and eventually directing the paths chemical reactions can take. Working with the femtosecond beamline at Lawrence Berkeley National Laboratory's Advanced Light Source, a team of scientists shows how it can be done.

NASA's Mars Exploration Rover Opportunity, now in its seventh year on Mars, has a new capability to make its own choices about whether to make additional observations of rocks that it spots on arrival at a new location. Software uploaded this winter is the latest example of NASA taking advantage of the twin Mars rovers' unanticipated longevity for real Martian test drives of advances made in robotic autonomy for future missions.

Scientists have solved the structure of a key protein from the virus that caused last year's "swine flu" influenza epidemic. The structure reveals that the virus shares many features with influenza viruses common in the early 20th century, helping to explain why, in general, older individuals have been less severely affected by the recent outbreak than younger ones.

Tyrannosaur bones are relatively familiar finds on the northern continents of the globe, cropping up everywhere from modern-day Colorado to China. But until now, they appeared to be oddly missing from the southern half of the globe. The discovery of a distinctively tyrannosaur-like hipbone in Victoria, Australia, however, might change the way scientists think about the distribution--and evolution--of this infamous group of dinosaurs.

An international team of astronomers has confirmed that the expansion of the universe is accelerating after looking at data from the largest-ever survey conducted by the Hubble Space Telescope. The researchers have, for the first time ever, used Hubble data to probe the effects of the natural gravitational "weak lenses" in space and characterize the expansion of the universe.
