NASA is a giant step closer to launching Americans again from U.S. soil. The space agency has picked Boeing and SpaceX to transport astronauts to the International Space Station in the next few years.
One sip of a perfectly poured glass of wine leads to an explosion of flavors in your mouth. Now, researchers have developed a nanosensor that can mimic what happens in your mouth when you drink wine. The sensor measures how you experience the sensation of dryness in the beverage. It has potential for both wine producers and research into the medicine of the future.
Chips that use light rather than electricity to move data would consume much less power— and energy efficiency is a growing concern as chips’ transistor counts rise. Now, researchers are describing a new technique for building molybdenum disulfide light emitters tuned to different frequencies, an essential requirement for optoelectronic chips.
Polish medical experts say that the preserved heart of 19th century composer Frederic Chopin shows signs of tuberculosis and possibly some other lung disease.
Scientists who created a deicing film for radar domes have now refined the technology to work as a transparent coating for glass. The new work could keep glass surfaces from windshields to skyscrapers free of ice and fog while retaining their transparency to radio frequencies.
Up to 80 percent of sexually active women are infected by the human papillomavirus at some point in their lives and infection with specific "high risk" strains of HPV has an established link to cervical cancer. Current screening by smear test is invasive and time-consuming. Urine samples may be a viable alternative.
Transmission of bacterial infections, including MRSA and MSSA, could be curbed by coating hospital surfaces with microscopic bumps that mimic the scaly surface of shark skin.
Researchers have developed a chin strap that can harvest energy from jaw movements. It is hoped that the device can generate electricity from eating, chewing and talking, and power a number of small-scale implantable or wearable electronic devices, such as hearing aids, cochlear implants, electronic hearing protectors and communication devices.
Chikungunya, a mosquito-borne virus similar to dengue, is spreading rapidly in the Western Hemisphere. Although there is little risk of it becoming a major threat in the U.S., health officials are still warning residents to exercise caution when outdoors as there have been confirmed cases in the U.S., mostly due to traveling citizens. Check out the infographic for more info on the relatively unspoken-about virus.
A new study into meat tenderness could refine the way people cook steak. Researchers conducted studies using microscopes to see what happens to meat cells while being cooked. They found that meat shrinks while cooking not once but twice.
Computer-driven cars have been testing their skills on California roads for more than four years— but until now, the DMV wasn't sure just how many were rolling around. That changed this week, when the agency issued testing permits that allowed three companies to dispatch 29 vehicles onto freeways and into neighborhoods— with a human behind the wheel in case the onboard computers make a bad decision.
Federal researchers are exploring several underwater sites where ships sank while navigating in the treacherous waters west of San Francisco in the decades following the Gold Rush. During the past week, researchers have used a remote-controlled underwater vehicle, equipped with sonar and video cameras, to examine and record the historic shipwrecks.
The meteorite impact that spelled doom for the dinosaurs 66 million years ago decimated the evergreens among the flowering plants to a much greater extent than their deciduous peers. Researchers have found evidence that, after the event, fast-growing, deciduous angiosperms had replaced their slow-growing, evergreen peers to a large extent.
The amazing variety of human faces– far greater than that of most other animals– is the result of evolutionary pressure to make each of us unique and easily recognizable. Our highly visual social interactions are almost certainly the driver of this evolutionary trend.
Waist circumference is a simple measure of total and intra-abdominal body fat. The prevalence of abdominal obesity and average waist circumference increased among U.S. adults from 1999 to 2012.
A new stereotactic radiosurgery system provides the same or a higher level of accuracy in targeting cancer tumors, and offers greater comfort to patients and the ability to treat multiple tumors at once, when compared to other radiation therapy stereotactic systems.
