In a study of national data on colon surgery, researchers found that while patients who undergo either minimally invasive laparoscopic surgery or the high-tech robotic approach have similar outcomes, robotic surgery is significantly more expensive.
A team of material scientists, chemical engineers and physicists has made another advance in their effort to use liquid crystals as a medium for assembling structures.
A new digital intelligence system that equips snowplows with custom-designed sensors is helping transportation officials clear winter roads more quickly and effectively.
A new study by neuroscientists is the first to directly compare brain responses to faces and objects with responses to colors. The paper reveals new information about how the brain’s inferior temporal cortex processes information.
The European Space Agency launched its star-surveying satellite Gaia into space Thursday, hoping to produce the most accurate 3D map of the Milky Way, and to better understand the evolution of our galaxy.
Many residents of Britain, Italy and Belgium imagine there to be a kind of north-south divide in their countries, marking a barrier between different social groups and regional characteristics. Now, a new study reveals that such divides can be seen in the patterns of communication in those countries and others.
As common as they have become across the U.S. and Canada, officials in dozens of towns and cities where oil trains travel say they are concerned about the possibility of a major derailment, spill or explosion, while their level of preparation varies widely.
A genetic trait known to make some people especially sensitive to stress also appears to be responsible for a 38 percent increased risk of heart attack or death in patients with heart disease.
Deep brain stimulation uses a surgical implant similar to a pacemaker to send electrical impulses to the brain. It may have a beneficial effect on driving ability for people with Parkinson’s disease.
Halomonas are a hardy breed of bacteria that can withstand heat, high salinity, low oxygen, utter darkness and pressures that would kill most other organisms. These traits enable the microbes to eke out a living in deep sandstone formations that also happen to be useful for hydrocarbon extraction and carbon sequestration.
Researchers have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation.
Tropical forests reduce peak runoff during storms and release stored water during droughts. The find lends credence to a controversial phenomenon known as the sponge effect, which is at the center of a debate about how to minimize flood damage and maximize water availability in the tropics.
Researchers have successfully tested the conversion of large particles of pinewood char in a gasification process, a step necessary for the mass production of synthetic liquid fuel from recalcitrant biomass.
Kathryn Medler and a team from the Univ. at Buffalo found that being severely overweight impaired the ability of mice to detect sweet flavors.
Pollen reflects more sunlight than previously known, and makes up to one third of the total amount of aerosol particles in the atmosphere.
Plants naturally produce millions of tiny spirals that scientists are turning into nanomotors for use in medicine and other fields.
