A new, open-source software that can help track the embryonic development and movement of neuronal cells throughout the body of the worm, is now available to scientists.
Almost 9 percent of popular apps downloaded from Google Play interact with websites that could compromise users' security and privacy, according to a new study. Researchers are now developing a tool that allows users to evaluate the riskiness of individual apps before downloading them.
Emotional appeal is among the factors increasing the chance that disaster communiques posted on social media by emergency management agencies will be retransmitted by recipients, researchers have found.
Researchers have developed power paper -- a new material with an outstanding ability to store energy. The material consists of nanocellulose and a conductive polymer.
Software developed to rate therapists on empathy using automatic speech recognition, natural language processing and machine learning.
Teens who are involved in dating abuse -- as either the perpetrator or the victim -- are more likely to also be involved in cyberdating abuse, research concludes. Further, teens who commit cyberdating violence against their partners are more likely to later be victimized by it and cyberviolence victims are more likely to later perpetrate this act.
Alpha particles, as the nuclei of the helium atom are also called, play a decisive role in the formation of heavier elements. Carbon, for instance, is formed from the fusion of these alpha particles. If another helium nucleus is added, oxygen is formed – another prerequisite for the development of life on Earth. Scientists are now presenting a new method using supercomputers to create detailed simulations of these birth processes inside stars. The method reduces the computational effort required and for the first time makes it possible, using the Jülich supercomputer JUQUEEN, to do a complete calculation of the scattering process of two alpha particles.
Go ahead, rant about the snow on Twitter. It can ease traffic on slippery, congested roads. That's the crux of a new study that examined how weather-related tweets can be analyzed to bolster computer models that, among other things, recommend safe driving speeds and which roads motorists should avoid during inclement weather.
Physicists have tracked down semiconductor nanostructure mechanisms that can result in the loss of stored information -- and halted the amnesia using an external magnetic field. The new nanostructures comprise common semiconductor materials compatible with standard manufacturing processes.
Industrial design researchers have solved two of the major challenges which prevent everyday items of clothing being turned into power sources for smartphones, tablets and other personal tech.
If quantum computers existed, they would revolutionize computing as we know it. Based on fundamental properties of matter, the potential power of these theoretical workhorses would solve problems in a new way, cracking extremely complex spy codes and precisely modeling chemical systems in a snap. Researchers have now created cleverly designed molecules to get one step closer to this goal.
A combination of detailed CT imaging and 3-D printing technology has been used for the first time in the surgical planning for separation of conjoined twins, according to a new study.
How can you tell if your mathematical model is good enough? Researchers have now implemented a Turing test in the form of an online game (with over 1700 players) to assess how good their models were at reproducing collective motion of real fish schools.
A rolling DNA-based motor that's 1,000 times faster than any other synthetic DNA motor has been devised by physical chemists, giving it potential for real-world applications, such as disease diagnostics.
Researchers have shown that by exploiting the polarization of light -- the physical phenomenon behind polarized sunglasses and most 3-D movie systems -- they can increase the resolution of conventional 3-D imaging devices as much as 1,000 times.
A collaboration between developmental psychologists and computer scientists has demonstrated that robots can "learn" much like babies - by experiencing the world and eventually imitating humans.
A new era of electronics and even quantum devices could be ushered in with the fabrication of a virtually perfect single layer of “white graphene."
Researchers have devised a way to estimate the distribution of wealth and poverty in an area by studying metadata from calls and texts made on cell phones. Such metadata contains information about the time, location and nature of the 'mobile phone events' but not their content.
With the aim of producing high-quality X-rays with minimal radiation exposure, particularly in children, researchers have developed a new approach to imaging patients based on the Xbox gaming system. Using proprietary software developed for the Microsoft Kinect system, researchers have adapted hands-free technology used for the popular Xbox system to aid radiographers when taking X-rays.
A sick person is obviously willing to pay for a good medical treatment, but economists have found that healthy people are potentially a much broader, if largely overlooked, market for medical innovations.
