© iStock/pixartdesign Researchers came up with a novel chemical solution based on the scents of predator bugs to repel herbivorous pests and safeguard crops. Herbivorous insects are currently a major danger to farmers' crop output. Predator insects that feed on herbivorous insects emit smells that the insects can detect. To escape being eaten, bugs change their...
Mount Rainier towers over Seattle's growing suburbs and Tacoma, Washington, rising more than 3 miles (14,410 feet) above sea level. Over the course of a year, about two million visitors explore Mount Rainier National Park to see the volcano, glaciers, forested ridges, and alpine meadows. The volcano's elegance, though, is deceiving. Mount Rainier is considered...
Volcanic monitoring types and methods employed. Credit: USGS Volcano Hazards Program Scientists must employ numerous tools to listen to and see activity inside a volcano in order to keep a watch on it. The USGS Volcano Hazards Program monitors volcanoes for signals of change that indicate volcanic reawakening. Surveillance must include several observations (earthquakes, ground...

'Modern medical science has offered us a choice where there was once none.' So stated John Simon at the International Medical Congress in London...
A human embryo in the lab at 9 days after fertilisation. The hypoblast (a group of cells outside the main embryo) sends a message to the embryo that initiates the development of the head-to-tail body axis. Using immunofluorescence analysis, the hypoblast is shown in green – these cells are asymmetrically distributed. A cavity is...
Scientists have discovered more proof that exercising while pregnant benefits both the mother and the unborn child. According to a study presented today (Sunday) at the "virtual" European Respiratory Society International Congress, Dr. Hrefna Katrin Gudmundsdottir asserted that a study of 814 infants had for the first time established a link between infants born to...

Fossils amassed from sediments in the Pacific Ocean reveal a previously unidentified and shocking shark extinction event. During this event, the populations of the predators abruptly dropped by as much as 90 percent, researchers report in the journal Science on June 4....
Crystals of the material hexagonal boron nitride can be etched so that the pattern you draw at the top transforms into a smaller and razor-sharp version at the bottom. These perforations can be used as a shadow mask to draw components and circuits in graphene. This process enables a precision that is impossible with...
Credit: Getty Images Research led by scientists at the University of Toronto highlights the considerable damages that can be triggered by common teeth-whitening agents. Published just recently in Nature Scientific Reports, the study assessed the dental cell damage caused by carbamide peroxide teeth-whitening remedies. It found that a suggested application of only 10 percent carbamide peroxide gel...
Via SmilesDrs.com Regenerative Dentistry Breakthrough Researchers at King's College London have developed a biological therapy that could revolutionize the way damaged teeth are treated. The therapy, which involves the use of a small molecule drug called Tideglusib, has been shown to stimulate the stem cells inside teeth, encouraging them to regenerate damaged tissue. Tooth decay and trauma...
