Tropical Cyclone 02A in the Arabian Sea east of Oman has been weakening and has become a tropical depression. The Global Precipitation Measurement or GPM mission core satellite analyzed the rainfall in the system.
A multinational team led by the Department of Energy's Oak Ridge National Laboratory Climate Change Science Institute has found the first positive correlation between human activity and enhanced vegetation growth.
Researchers from the University of Missouri and partner institutions are exploring how ethnic and gender variables affect retention rates, goal setting and satisfaction among engineering students. Preliminary findings in the middle of this five-year study found no differences in retention between Latino and white engineering students, but did show differences between men and women. Their study could help shape methods needed to retain students in engineering fields.
One of the most basic components of any communications network is a power splitter that allows a signal to be sent to multiple users and devices. Researchers from Brown University have now developed just such a device for terahertz radiation -- a range of frequencies that may one day enable data transfer up to 100 times faster than current cellular and Wi-Fi networks.
Engineers and neuroscientists at the University of Sheffield have demonstrated for the first time that the cells in the retina carry out key processing tasks. This could pave the way for improving retinal implants and therefore the sight of thousands of people suffering from retinal disorders.
Global patterns of adoption spreading are induced by local adoption cascades initiated by multiple spontaneous adopters arriving at a constant rate, amplified by a large number of adoptions induced by social influence, and controlled by individuals who are immune to the actual adoption.
Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, the University of Bern, Switzerland, and Washington State University demonstrated the importance of jasmonate-dependent nicotine production for the survival of tobacco plants which are attacked by mammalian herbivores.
Physicists at the University of Zurich have developed a system that enables them to switch back and forth the adhesion and stiction (static friction) of a water drop on a solid surface. The change in voltage is expressed macroscopically in the contact angle between the drop and the surface. This effect can be attributed to the change in the surface properties on the nanometer scale.
For this episode of BioScience Talks, we're joined by Gene Drive Committee co-chair James P. Collins of Arizona State University and committee member Joseph Travis of Florida State University. They fill us in on the specifics of the new committee report and on the future of gene drives.
A new national survey by Health Union of more than 1,000 individuals with Irritable Bowel Syndrome (IBS) reveals that the condition is difficult to diagnose and often even more difficult to treat. Respondents often found healthcare providers and the public in general lacking in empathy and understanding of the full impact of the disease. Self-treatment often becomes the norm and controlling symptoms difficult.
