Using ultrasound technology to visualize the tongue’s shape and movement can help children with difficulty pronouncing “r” sounds, according to a small study. The ultrasound intervention was effective when individuals were allowed to make different shapes with their tongue in order to produce the “r” sound, rather than being instructed to make a specific shape.
Highly trained technical divers with a Florida-based group are helping Italian researchers to unlock an ancient shipwreck thought to date to the second Punic Wars between Rome and Carthage. Able to descend hundreds of feet further than most divers, they aide the archaeologists by swimming about the wreck fetching artifacts— as no robotic submersible can.
A new report has highlighted how contemporary chemical and life science research could be applied in the study or creation of incapacitating chemical agent weapons.
Amoebas aren’t the only cells that crawl: movement is crucial to development, wound healing and immune response in animals, not to mention cancer metastasis. In two new studies, researchers have answered long-standing questions about how complex cells sense the chemical trails that show them where to go— and the role of cells’ internal “skeleton” in responding to those cues.
Jonas Salk was an American Jewish physician and medical researcher, born in New York City on Oct. 28, 1914, who developed the first safe and effective vaccine for poliomyelitis.
Scientists combined high-resolution 3-D confocal microscopy and computer-automated analysis of the images to survey the fission yeast genome with respect to three key cellular processes simultaneously: cell shape, microtubule organization and cell cycle progression.
Heart surgery patients who received newly donated blood have significantly fewer post-operative complications than those who received blood that had been donated more than two weeks before their surgery, according to a study that examined a hospital’s records of non-emergency heart surgeries performed over almost nine years.
Neuroscientists have discovered that just one session of aerobic exercise is enough to spark positive changes in the brain that could lead to improved memory and coordination of motor skills. They found changes in the brain that were likely to make it more "plastic" after only 30 minutes of vigorous exercise.
Ferroelectric materials– commonly used in transit cards, gas grill igniters, video game memory and more– could become strong candidates for use in next-generation computers. Researchers have found an easy way to improve the performance of ferroelectric materials in a way that makes them viable for low-power computing and electronics.
Nanodiamonds are providing scientists with new possibilities for accurate measurements of processes inside living cells with potential to improve drug delivery and cancer therapeutics.
Researchers are reporting the transmission of a record high 255 Terabits/sec over a new type of fiber, allowing 21 times more bandwidth than currently available in communication networks. This new type of fiber could be an answer to mitigating the impending optical transmission capacity crunch caused by the increasing bandwidth demand.
A potentially lethal bacterium protects itself by causing immune tunnel vision, according to a study. By tricking the immune system into focusing on one bug-associated factor, the bacterium Staphylococcus aureus dodges the production of antibodies that would otherwise protect against infection.
Starting today, millions of people who have avoided colon cancer screening can get a new home test that's noninvasive and doesn't require the preparation most other methods do. The test is the first to look for cancer-related DNA in stool. But deciding whether to get it is a more complex choice than ads for the test make it seem.
The WHO warns that there could be 10,000 new Ebola cases a week by December if the world doesn't get more heavily involved. The responses by the U.S., Britain and France are largely based on historical or colonial ties. France has focused its efforts on Guinea; Britain on Sierra Leone; and the U.S. is giving much of its aid to Liberia.
Lasers are so deeply integrated into modern technology that their basic operations would seem well understood. Re-examining longstanding beliefs about the physics of these devices, engineers have shown that carefully restricting the delivery of power to certain areas within a laser could boost its output by many orders of magnitude.
