Journalism changed forever by user-generated content

Mon, 05/23/2016 - 12:38
The rise of User-Generated Content (UGC) -- information submitted by members of the public or posted on social media -- has changed journalism forever, according to a new study.

World record in terrestrial radio transmission: Multi-Gigabit wireless communication

Mon, 05/23/2016 - 12:38
Transmitting the contents of a conventional DVD in under ten seconds by radio transmission is incredibly fast -- and a new world record in wireless data transmission. With a data rate of 6 Gigabit per second over a distance of 37 kilometers, the project exceeded the state of the art by a factor of 10.

Complex inter-dependent data: Looking beyond conventional networks can lead to better predictions

Fri, 05/20/2016 - 18:29
New research suggests that current algorithms to represent networks have not truly considered the complex inter-dependencies in data, which can lead to erroneous analysis or predictions. Scientists have now developed a new algorithm that offers the promise of more precise network representation and accurate analysis.

Scientists create computational tool for greater understanding of metabolic network

Fri, 05/20/2016 - 16:06
Researchers present the first genome-scale reconstruction of the C. elegans metabolic network and show that scientists can use mathematical simulation to convert bacterial diet into C. elegans biomass.

Scientists explain how the giant magnetoelectric effect occurs in bismuth ferrite

Fri, 05/20/2016 - 16:06
Electromagnetic effect allows to control magnetic polarization of a material by applying external electric field. Materials with such properties may be used to develop a new generation of ultra-energy efficient computer memory.

In obese prostate cancer patients, robotic surgery reduces risk of blood loss

Fri, 05/20/2016 - 16:06
In obese prostate cancer patients, robotic-assisted surgery to remove the prostate reduces the risk of blood loss and prolonged hospital stays, a new study has found.

Long term effects of cardiac regenerative therapies in a left ventricle

Fri, 05/20/2016 - 15:03
To increase our understanding of cardiac regenerative therapies, a team of researchers has recently developed a computational model capable of simulating the long-term effects of these therapies.

Large-scale technique to produce quantum dots

Thu, 05/19/2016 - 20:12
Scientists have demonstrated a method to produce significant amounts of semiconducting nanoparticles for light-emitting displays, sensors, solar panels and biomedical applications.

Using static electricity, microrobots can land and stick to surfaces

Thu, 05/19/2016 - 18:45
Roboticists demonstrate that their flying microrobots, nicknamed the RoboBees, can now perch during flight to save energy - like bats, birds or butterflies.

Scientists create 'rewritable magnetic charge ice'

Thu, 05/19/2016 - 18:45
Scientists have developed a new material, called 'rewritable magnetic charge ice,' that permits an unprecedented degree of control over local magnetic fields and could pave the way for new computing technologies.

Social media poses threat to people with intellectual disabilities

Thu, 05/19/2016 - 16:09
People with intellectual disabilities are more susceptible to exploitation and abuse, and the rise of the internet only increases their vulnerability, say researchers.

New angles on visual cloaking of everyday objects

Thu, 05/19/2016 - 16:07
Using the same mathematical framework as the Rochester Cloak, researchers have been able to use flat screen displays to extend the range of angles that can be hidden from view. Their method lays out how cloaks of arbitrary shapes, that work from multiple viewpoints, may be practically realized in the near future using commercially available digital devices.

Assistive tech to tackle dementia isolation

Thu, 05/19/2016 - 12:24
Moblie and wearable technology used to support independent living for people with dementia could hold the key to cutting social isolation.

Fighting the Zika virus with the power of supercomputing

Thu, 05/19/2016 - 12:18
A new international project is aiming to identify potential drugs to fight the Zika virus, using the supercomputing power of IBM's World Community Grid to dramatically reduce the time it would otherwise take.

To catch a poacher: GIS, drones can improve elephant conservation

Wed, 05/18/2016 - 21:04
Applying a suite of geographical information system (GIS) tools can improve monitoring for elephant poaching, according to researchers. Investigating Tsavo, a region in southwest Kenya that is home to that country's largest elephant population, the researchers tried to identify methods that local conservation groups could use to reduce poaching.

Your friends have more friends than you do

Wed, 05/18/2016 - 21:04
No matter how smart and funny you think you are, those you follow on Twitter really do have a larger following than you. And the same holds true for Facebook. But there is no reason to feel badly about any of this, according to researchers who say that it is all due to the inherently hierarchical nature of social media networks, where, in the social hierarchy of connections, people mostly either follow up or across; they rarely follow down.

Future geriatricians 'become' Alfred, a 74-year-old patient, using virtual reality

Wed, 05/18/2016 - 19:34
A virtual reality experience transforms the user into a 74-year-old named Alfred in order to see his perspective as a medical patient.

Educational debt for emergency medicine bigger than average mortgage

Wed, 05/18/2016 - 19:29
The average educational debt carried by emergency medicine residents is approximately 25 percent higher than the average mortgage in the United States, according to the results of a recent study, and has profound effects on EM residents career and life choices.

Researchers develop new way to decode large amounts of biological data

Wed, 05/18/2016 - 19:28
In recent years, the amount of genomic data available to scientists has exploded. This trove of genetic information has created a problem: how can scientists quickly analyze all of this data.
