It took marine sponges millions of years to perfect their spike-like structures, but research mimicking these formations may soon alter how industrial coatings and 3-D printed objects are produced.
Researchers have made a crucial step toward nuclear spintronic technologies. They have gotten nuclear spins to line themselves up in a consistent, controllable way, and they have done it using a high-performance material that is practical, convenient, and inexpensive.
Researchers have designed a responsive hybrid material that is fueled by an oscillatory chemical reaction and can perform computations based on changes in the environment or movement, and potentially even respond to human vital signs.
If it were up to Internet-savvy Americans, more of them would be emailing or sending Facebook messages to their doctors to chat about their health. That's the result of a national survey that was sent to more than 4,500 customers of a retail pharmacy. Respondents tended to be well educated, in good health, and frequent users of Facebook.
Researchers have analyzed patents registered in China over the last three years for industry 4.0 technologies. The first study to be published on the topic shows that Chinese researchers have patented important inventions in the fields of wireless sensor networks, embedded systems, low-cost robots and big data, indicating that China may be leading the pack when it comes to production data in the future.
Inspired by octopuses and chameleons, researchers have developed technique for using a metallic nanostructure to create the first full-color, flexible display so thin it could be used to create color-changing clothing.
A form of 'virtual-reality' therapy may help people with alcohol dependence reduce their craving for alcohol, a new study suggests. The findings come from a small study of just 10 patients. But researchers said they are optimistic about the potential for virtual reality as a therapy for alcohol use disorders.
A new smartphone has been developedwith iris recognition and a professor says the technology is giving people more options to protect their electronic devices and should be available in the United States in the near future.
When individual random quantities, such as reactions in the body, are instead correlated, and multiplied, the process gives rise to the ubiquitous, highly skewed pattern, and that this pattern is more accurately called a Weibull distribution, scientists explain.
Researchers have developed a new approach for forming 3-D shapes from flat, 2-D sheets of graphene, paving the way for future integrated systems of graphene-MEMS hybrid devices and flexible electronics.
When grain and other commodity prices experienced explosive episodes between 2004 and 2013, the finger pointed toward index traders as the cause. Researchers identified and date-stamped both upward and downward price bubbles for grain during that time period. They found that not only were index traders not to blame but that the bubbles didn't last nearly as long as many thought they did.
Scientists have developed a new power converter chip that can harvest more than 80 percent of the energy trickling into it, even at the extremely low power levels characteristic of tiny solar cells. Previous experimental ultralow-power converters had efficiencies of only 40 or 50 percent.
Just because more men pursue careers in science and engineering does not mean they are actually better at math than women are. The difference is that men think they are much better at math than they really are. Women, on the other hand, tend to accurately estimate their arithmetic prowess.
A breakthrough in cancer genomics has been achieved by developing a novel big data analysis platform for analyzing the interactions among genes. The analysis platform unveils the unregulated patterns of gene network in cancer and discovers potential diagnostic and therapeutic target genes, Nucleophosmin (NPM1) and its associated genes, in Chronic Myelogenous Leukemia (CML).
Fish may seem to glide effortlessly through the water, but the tiny ripples they leave behind are evidence of a constant give-and-take of energy between the swimmer and its aqueous environment -- a momentum exchange that propels the fish forward but is devilishly tricky to quantify. Now, new research shows that a fish's propulsion can be understood by studying vortices in the surrounding water as individual units instead of examining the flow as a whole.
For someone suffering from paralysis or limited mobility, visiting with other people is extremely difficult. Scientists have been working on a revolutionary brain-machine approach in order to restore a sense of independence to the disabled. The idea is to remotely control a robot from home with one's thoughts. The research, involving numerous subjects located in different countries, produced excellent results in both human and technical terms.
A new approach to realizing color displays breaks away from the RGB construct and provides a rich palette of colors at each mirror-pixel location.
There is no guarantee that smart, personal coaching apps can live up to claims to make our lives more healthy and more productive. Users may receive incorrect, commercially slanted, or ineffective advice. It is also unclear to users how producers of e-coaches deal with the intimate information that is collected. Researchers now aim to implement standards that will assure data privacy, and, moreover, quality, reliability and effectiveness of provided services.
Scientists have developed a new technique to rapidly create multi-layered, self-assembled grids could transform the manufacture of high-tech coatings for anti-reflective surfaces, improved solar cells, and touchscreen electronics.
Researchers are focusing on printed electronics: using inkjet technology to print electronic nanomaterials onto flexible substrates. When compared to traditional methods used in microelectronics fabrication, the new technology conserves material and is more environmentally friendly.
