Imitation is the most sincere form of flattery, unless you are an app developer

Mon, 04/09/2018 - 17:56
One out of two mobile apps released is a clone of an existing app. However, new research shows the success of the original app is not always adversely affected by these clone apps. The study found that whether the copycat app increases or decreases the number of downloads of the original is dependent upon the quality of the copy.

Ultra-powerful batteries made safer, more efficient

Mon, 04/09/2018 - 15:25
Researchers are laying the foundation for more widespread use of lithium metal batteries. They have developed a method to mitigate the formation of dendrites -- crystal-like masses -- that damage the batteries' performance.

Mirror-like physics of superconductor-insulator transition

Mon, 04/09/2018 - 14:39
The mirror-like physics of the superconductor-insulator transition operates exactly as expected. Scientists know this to be true following the observation of a remarkable phenomenon, the existence of which was predicted three decades ago but that had eluded experimental detection until now. The observation confirms that two fundamental quantum states, superconductivity and superinsulation, both arise in mirror-like images of each other.

China's STEM research environment in higher education

Fri, 04/06/2018 - 17:01
China's President Xi Jinping has repeatedly stated his aim of transforming the country into a 'science and technology superpower.' But when it comes to China's science, technology, engineering and math (STEM) research environment, newly published research suggests that they may have a long way to go.

Computer system transcribes words users 'speak silently'

Thu, 04/05/2018 - 17:30
Researchers have developed a computer interface that can transcribe words that the user verbalizes internally but does not actually speak aloud. Electrodes in the device pick up neuromuscular signals in the jaw and face that are triggered by internal verbalizations -- saying words 'in your head' -- but are undetectable to the human eye.

The traits of fast typists discovered by analyzing 136 million keystrokes

Thu, 04/05/2018 - 14:17
An online study with 168,000 people shows large variation in typing speeds and styles. The dataset is the largest ever on everyday typing and exposed several factors that differentiate fast vs. slow typists. In addition to making fewer errors, the researchers found that fastest typists rely on so-called 'rollover' where a letter key is typed before the previous one is released.

Using friends to fight online harassment

Thu, 04/05/2018 - 13:32
Harassment on social media is often so subtle that an algorithm alone might not pick up on various cues. But what if people could actually leverage their friends to help moderate their accounts and shield them from abusive messages?

Breakthrough made in atomically thin magnets

Wed, 04/04/2018 - 16:58
Researchers have become the first to control atomically thin magnets with an electric field, a breakthrough that provides a blueprint for producing exceptionally powerful and efficient data storage in computer chips, among other applications.

Cost effective technique for mass production of high-quality graphene

Wed, 04/04/2018 - 13:51
Scientists have developed an economical and industrially viable strategy to produce graphene. The new technique addresses the long-standing challenge of an efficient process for large-scale production of graphene, and paves the way for sustainable synthesis of the material.

Pulling valuable metals from e-waste makes financial sense

Wed, 04/04/2018 - 13:39
Electronic waste -- including discarded televisions, computers and mobile phones -- is one of the fastest-growing waste categories worldwide. For years, recyclers have gleaned usable parts, including metals, from this waste stream. That makes sense from a sustainability perspective, but it's been unclear whether it's reasonable from an economic viewpoint. Now researchers report that recovering gold, copper and other metals from e-waste is cheaper than obtaining these metals from mines.

Smart ink adds new dimensions to 3-D printing

Wed, 04/04/2018 - 13:39
New smart ink turns 3-D-printed structures into objects that can change shape and color.

Artificial intelligence helps predict likelihood of life on other worlds

Wed, 04/04/2018 - 13:39
Developments in artificial intelligence may help us to predict the probability of life on other planets. The study uses artificial neural networks (ANNs) to classify planets into five types, estimating a probability of life in each case, which could be used in future interstellar exploration missions.

Scientists merge statistics, biology to produce important new gene computational tool

Tue, 04/03/2018 - 21:14
Researchers have come up with a computational tool that increases the reliability of measuring how strongly genes are expressed in an individual cell.

Debt matters: Women use credit to bridge income gaps, while men are less cautious

Tue, 04/03/2018 - 18:44
A new study on attitudes about debt shows that men have greater tolerance for using debt to buy luxury items, while women are more accepting of debt used in appropriate ways, including to bridge income gaps.

New satellite method enables undersea estimates from space

Tue, 04/03/2018 - 18:44
Researchers have developed a statistical method to quantify six important ocean particles from satellite data.

Apps to keep children safe online may be counterproductive

Tue, 04/03/2018 - 18:44
Mobile apps designed to help parents keep their children safe from online predators may actually be counterproductive, harming the trust between a parent and child and reducing the child's ability to respond to online threats, conclude two new studies.

Anticipating the dangers of space

Tue, 04/03/2018 - 18:03
Astronauts and future space tourists face risks from radiation, which can cause illness and injure organs. Researchers used supercomputers to investigate the radiation exposure related to the Manned Orbital Laboratory mission, planned for the 1960s and 70s, during which a dangerous solar storm occurred. They also explored the historical limitations of radiation research and how such limitations could be addressed in future endeavors.

Nanoparticle films for high-density data storage

Tue, 04/03/2018 - 15:10
New nanoparticle-based films that are more than 80 times thinner than a human hair may provide materials that can holographically archive more than 1,000 times more data than a DVD in a 10-by-10-centimeter piece of film.

Ancient paper art, kirigami, poised to improve smart clothing

Tue, 04/03/2018 - 15:10
Scientists describe how kirigami has inspired its efforts to build malleable electronic circuits. Their innovation -- creating tiny sheets of strong yet bendable electronic materials made of select polymers and nanowires -- could lead to improvements in smart clothing, electronic skin and other applications that require pliable circuitry.
