An enthusiastic group of non-experts, working through an online interface and receiving feedback from lab experiments, has produced designs for RNA molecules that are consistently more successful than those generated by the best computerized design algorithms, researchers report.
A new study has found that healthy 12-year-olds who score well in addition and multiplication have higher-quality white matter tracts. This correlation does not appear to apply to subtraction and division.
An algorithm could help scientists assist citrus growers predict when to plant and harvest their crop further in advance.
Doctors worldwide now use tools such as FRAX, a widely available online calculator, to help identify patients in need of osteoporosis treatment. A new position paper by the IOF Epidemiology and Quality of Life Working Group has assessed the uptake of FRAX worldwide. The study concludes that there were approximately 2.3 million FRAX calculations during a one-year period beginning in May 2012, with enormous variation in worldwide usage.
New types of solotronic structures, including the world's first quantum dots containing single cobalt ions, have been created and studied. The materials and elements used to form these structures allow us forecast new trends in solotronics -- a field of experimental electronics and spintronics of the future, based on operations occurring on a single-atom level.
Physicists have moved an atom inside a crystal and investigate its function. Nanotechnology is a thriving science. Parts for computers for example are becoming smaller and more precise by the minute. One of the most efficient computers would be the so-called quantum computer. Up to now, its existence has been merely a concept that is based on the laws of quantum mechanics. Here, the ability to control the state of single atoms is decisive. For the first time ever, scientists have managed to move single atoms vertically inside a crystal.
Educators have developed and tested Civic Seed, an interactive video game to see if it can better prepare college students to engage with the community —- and if it can do so more effectively than a non-gaming alternative.
A new, free app will allow smartphone users to measure their cellphone use. Computer scientists and psychologists have developed an application for this purpose. Whoever installs it can see, e.g., how much time s/he spends on the phone or which apps s/he uses most frequently. The relevant key data is sent to a server anonymously for the scientists to analyze. They are already using a similar technology for the early detection of depression.
Researchers are developing a novel compound known to reverse the spread of malignant breast cancer cells. The vast majority of deaths from cancer result from its progressive spread to vital organs, known as metastasis. In breast cancer up to 12,000 patients a year develop this form of the disease, often several years after initial diagnosis of a breast lump. In a recent series of studies, researchers identified a previously unknown critical role for a potential cancer causing gene, Bcl3, in metastatic breast cancer.
When physicians spend too much time looking at the computer screen in the exam room, nonverbal cues may get overlooked and affect doctors' ability to pay attention and communicate with patients, according to a study.
As hospitals and doctors' offices across the country race to join online systems that let them share medical information securely, a new study suggests that these systems may already be helping cut unnecessary care. Fewer emergency patients got repeated medical scans when they went to a hospital that takes part in a health information exchange,according to new findings.
Scientists have found that youth influence their parents in all technologies studied (computer, mobile Internet, social networking) up to 40 percent of the time. The children's scores were higher compared to parents, showing that parents don't necessarily recognize the influence.
Scientists have developed a mathematical model to predict how a patient’s tumor is likely to behave and which of several possible treatments is most likely to be effective.
Researchers have produced an advanced web-based tool that lets physically separated participants collaborate on model-based systems engineering projects. The program utilizes open-source software components to allow users to visualize a system's potential expense alongside its performance, reliability and other factors.
Scientists have called for data held in biobanks to be made accessible to the people donating material and data to them.
A new long-range wireless tag detection system, with potential applications in health care, environmental protection and goods tracking, can pinpoint items with near 100 percent accuracy over a much wider range than current systems.
Stem cells can turn into heart cells, skin cells can mutate to cancer cells; even cells of the same tissue type exhibit small heterogeneities. Scientists use single-cell analyses to investigate these heterogeneities. But the method is still laborious and considerable inaccuracies conceal smaller effects. Scientists have now found a way to simplify and improve the analysis by mathematical methods.
Silicon-based electronics has certain limits, in the physical sense of the word: this type of circuit can never become “nano” because of the physical laws governing the flow of electrons. This imposes a halt to the process of miniaturization of electronic devices. One of the possible solutions is to use molecules as circuits, but their poor conduction capabilities make them unlikely candidates. There is, however, a possible way around this, which was investigated in a recent article.
Surveillance minimization -- where surveillance is the exception, not the rule -- could help rebuild public trust following revelations about the collection of personal data, according to a law academic.
Bioengineers showed that tiny blood vessels grow better in the laboratory if the tissue surrounding them is less dense. Then the researchers created a computer simulation to predict such growth accurately – an early step toward treatments to provide blood supply to tissues damaged by diabetes and heart attacks and to skin grafts and implanted ligaments and tendons.
