Researchers have developed and patented a new source of light emitter based on boron nitride nanotubes and suitable for developing high-efficiency optoelectronic devices.
A team of experimental and theoretical physicists has studied a single micrometer-sized atom. This atom contains tens of thousands of normal atoms in its electron orbital.
Couples shouldn't let their thumbs do the talking when it comes to serious conversations, disagreements or apologies.
Researchers have found internet forums provide a support network for socially isolated young people. However, they also conclude that the internet is linked to an increased risk of suicide and self-harm among vulnerable adolescents. Following what is thought to be the biggest review of existing studies into internet use and young people, the researchers suggest that in future, clinical assessments of such young people should include questions about the online content they have viewed.
Biologists have discovered fundamental rules for leaf design that underlie the ability of plants to make leaves that vary enormously in size.
Using next generation sequencing and population genetic modeling, scientists have found that CMV evolves rapidly and dramatically in humans. These findings provide new genetic targets that could impede the evolution of CMV and prevent its spread.
Scientists were able to laser scan a 40 meter-long skeleton of the vast Cretaceous Agentinosaurus dinosaur. Then using an advanced computer modeling technique involving the equivalent of 30,000 desktop computers they recreated its walking and running movements and tested its locomotion ability tested for the very first time.
A new report looks at media consumption by individuals in and out of the home, excluding the workplace, between 2008 and 2015, breaking “media” down into 30 categories of media type and delivery (e.g. television, social media, computer gaming) and conclude that the average person will consume 15.5 hours per day by 2015.
New barrier films could better protect electronics in harsh environments, and are being developed for public consumption.
Scientists have used Google's online street view scans to document the damage caused by the 2009 L'Aquila earthquake and suggests that the database would be a useful tool for surveying damage caused by future earthquakes.
Many of today's technologies, from hybrid car batteries to flat-screen televisions, rely on materials known as rare earth elements (REEs) that are in short supply, but scientists are reporting development of a new method to recycle them from wastewater. The process could help alleviate economic and environmental pressures facing the REE industry.
Gimball bumps into and ricochets off of obstacles, rather than avoiding them. This 34-cm in diameter spherical flying robot buzzes around the most unpredictable, chaotic environments, without the need for fragile detection sensors.
A prototype new IP layer for the internet has been designed. Called PURSUIT, it replaces a system in which we obtain information from servers with a model similar to p2p file-sharing, but on a massive, internet-wide scale. Content would be accessed not from servers, but in fragments from other people's computers.
Video gaming causes increases in the brain regions responsible for spatial orientation, memory formation and strategic planning as well as fine motor skills. This has been shown in a new study. The positive effects of video gaming may also prove relevant in therapeutic interventions targeting psychiatric disorders.
Considering 798 to be an odd number is endemic to human cognition, reveals a new study. A common assumption in the cognitive sciences is that thinking consists of following sets of rules (as it does in a computer). A recent research argues that unlike digital computers, which are designed to follow rules, the computations performed by the neural networks that make up our brain are inherently context dependent. People sometimes make seemingly strange mistakes like thinking that 798 is an odd number despite knowing how to identify odd and even numbers.
GSM, WiFi, Bluetooth, 4G, GPS: a smartphone already has to handle many wireless standards. And this number will only increase further. There are still no good filters to keep all those future standards separate. Researchers have now taken an important step with a new type of filter, based on micromechanics.
Whether you want to investigate objects in space, characterize the quality of light sources, optimize photovoltaics modules or analyze chemical compounds, measuring the spectrum of light- or heat sources is often the method of choice. Conventional procedures thereby generate radiation distribution curves which are distorted and have to be subsequently corrected. Scientists have now developed a mathematical procedure which yields clearly improved results and can be applied in numerous fields of radiometry and photometry. The software required can be downloaded free of charge.
A plasma-containing crystal, tunable by varying a voltage, could increase the bandwidth of high-speed communication networks and generally enhance high-speed electronics.
Researchers reveal the true identity of the brains of mathematicians Carl Friedrich Gauss and Conrad Heinrich Fuchs.
After more than 40 years of intense research, experimental physicists still seek to explore the rich behavior of electrons confined to a two-dimensional crystalline structure exposed to large magnetic fields. Now scientists have developed a new experimental method to simulate these systems using a crystal made of neutral atoms and laser light. In such artificial quantum matter, the atoms could be exposed to a uniform effective magnetic field several thousand times stronger than in typical condensed matter systems.
