Sequencing the genomes of tumor cells has revealed thousands of genetic mutations linked with cancer. However, sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process. Now, researchers have developed a new way to model the effects of these genetic mutations in mice.
A research team has sequenced the genome of a 45,000-year-old modern human male from western Siberia. The comparison of his genome to the genomes of people that lived later in Europe and Asia show that he lived close in time to when the ancestors of present-day people in Europe and eastern Asia went different ways.
Researchers have found a definitive link between gait– the way someone walks– and early changes in cognitive function in people with Parkinson's disease. And the find could mean that gait may be used as an early warning sign to help predict the development of cognitive impairment and dementia in Parkinson’s.
An optical engineer led the development of the Rapid Adaptive Zoom for Assault Rifles (RAZAR) prototype. At the push of a button, RAZAR can toggle between high and low magnifications, enabling soldiers to zoom in without having to remove their eyes from their targets or their hands from their rifles.
So long, Silicon Valley. These days entrepreneurs and engineers are flocking to a place better known for wave surfing than Web surfing. Amid the palm trees and purple sunsets of the Southern California coastline, techies have built "Silicon Beach."
Justin Yeakel and a team used depictions of animals in ancient Egyptian artifacts to assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years.
Drawing blood and testing it is standard practice for many medical diagnostics. As a less painful alternative, scientists are developing skin patches that could, one day, replace the syringe.
Tetsuya Theodore Fujita, born Oct. 23, 1920, was a Japanese-American meteorologist who increased the knowledge of severe storms. He was known as "Mr. Tornado" as a result of the Fujita scale, which he and his wife, Sumiko, developed for measuring tornadoes on the basis of their damage.
A TV news cameraman treated for Ebola is going home today, the fifth patient transported from West Africa to recover at a U.S. hospital, as President Barack Obama brought together top aides and his new Ebola "czar," Ron Klain, to coordinate a national response to the deadly disease.
New research shows vulnerable patients in the intensive care unit who received enhanced oral care from a dentist were at significantly less risk for developing a lower respiratory tract infection, like ventilator-associated pneumonia, during their stay.
Just in time for flu season, a new study of “the mother of all pandemics” could offer insight into infection control measures for the flu and other epidemic diseases. In 1918, the Spanish flu killed 50 million people worldwide, 10 to 20 million of whom were in India. In the U.S. alone, the Spanish flu claimed 675,000 lives in nine months.
In the three years since a new standard for gas mileage has been in effect, automakers have surpassed it each year, improving new vehicle fuel economy by about a mile per gallon annually.
While numerous studies have affirmed nature’s stress-reduction properties, scientists haven’t known the specific amount of exposure needed to induce these calming effects. Now, researchers have found that viewing 3-D videos of residential streets with varying amounts of tree canopy significantly improved participants’ physiological and psychological recovery from a stressful experience.
Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts and valuable natural resources escaping into the air, ground and water. Now, scientists say they have developed a new software-based method that finds leaks even when they’re small, which could help prevent serious incidents— and save money for customers and industry.
Frying is one of the world’s most popular ways to prepare food. But before dunking your favorite food in a vat of just any old oil, consider using olive. Scientists are reporting that olive oil withstands the heat of the fryer or pan better than several seed oils to yield more healthful food.
