Half of the most popular news on Twitter is not covered by traditional news media sources

Fri, 07/31/2015 - 22:26
Half of the news that appears on Twitter as 'trending topics' goes unmentioned in the traditional news media, and when both sources carry it, 60 percent of the stories appear first on the social network. Those are some of the conclusions of a study which analyzes the dissemination of news on Twitter compared with the traditional media.

Brain-controlled prosthesis nearly as good as one-finger typing

Fri, 07/31/2015 - 14:37
Brain-controlled prostheses sample a few hundred neurons to estimate motor commands that involve millions of neurons. Sampling errors can reduce the precision and speed of thought-controlled keypads. A new technique can analyze this sample and make dozens of corrective adjustments in the blink of an eye to make thought-controlled cursors more precise.

Robotic insect mimics Nature's extreme moves

Thu, 07/30/2015 - 20:24
By analyzing the natural mechanics of the water strider that enable it to launch off water's surface scientists have emulated this extreme form of locomotion in novel robotic insects.

Computer model forecasts flu outbreaks in a subtropical climate

Thu, 07/30/2015 - 20:20
It is possible to predict the timing and intensity of influenza outbreaks in subtropical climates like Hong Kong where flu seasons can occur at different times and more than once during a year, scientists have shown for the first time.

Ants in the lead: How ants cooperate in steering food to their nest

Thu, 07/30/2015 - 14:45
A physics-based model can explain how ants cooperate in steering food to their nest. To lug a large object, a number of ants surround it -- the back ones lift, those on the leading edge pull. How do they stay on track, instead of simply pulling all around in a sort of tug-of-war? Scientists used video analysis to track the individual movements of ants in a group that was carrying a large food item toward their nest.

Research could play major role in curbing illegal ivory sales

Thu, 07/30/2015 - 12:12
A new automated data mining system could lead to a dramatic increase in the detection of potentially illegal online sales of elephant ivory through eBay. Law enforcement agencies and conservationist are expected to make use of the system in their ongoing battle against illegal ivory sales. At the moment, identifying illegal elephant ivory being sold online is a laborious, tedious and expensive task, even for experts.

This could replace your silicon computer chips

Thu, 07/30/2015 - 12:11
This could replace your silicon computer chips, scientists say: a new semiconductor material made from black phosphorus may be a candidate to replace silicon in future tech.

First reports of robotic surgery for advanced vena cava tumor thrombus due to kidney cancer

Thu, 07/30/2015 - 12:11
Surgery is required when cancer of the kidney causes a Level III thrombus, or clot, to develop in the major vein leading back to the heart. Traditionally this complicated procedure, inferior vena cava (IVC) thrombectomy, is performed using a large open incision, primarily because the vein is often difficult to reach. In a new article, a team of surgeons describe the first cases in which this procedure has been successfully performed robotically, using only seven small incisions and four robotic tools.

Small study affirms accuracy of free mobile app that screens for liver disease in newborns

Wed, 07/29/2015 - 19:51
Researchers have verified the ability of a free smartphone app to accurately read, interpret and record the color of a newborn's poop as a possible early symptom of biliary atresia -- a rare disorder that accounts for nearly half of pediatric end-stage liver disease in the United States.

New computer-based technology may lead to improvements in facial transplantation

Wed, 07/29/2015 - 18:24
Following several years of research and collaboration, physicians and engineers say they have developed a computer platform that provides rapid, real-time feedback before and during facial transplant surgery, which may someday improve face-jaw-teeth alignment between donor and recipient.

Proof-of-concept study shows successful transport of blood samples with small drones

Wed, 07/29/2015 - 18:24
In a proof-of-concept study, researchers have shown that results of common and routine blood tests are not affected by up to 40 minutes of travel on hobby-sized drones.

Shoring up Tor: Researchers mount successful attacks against popular anonymity network -- and show how to prevent them

Wed, 07/29/2015 - 18:20
With 2.5 million daily users, the Tor network is the world's most popular system for protecting Internet users' anonymity. Researchers have now demonstrated a vulnerability in Tor's design. They show that an adversary could infer a hidden server's location, or the source of the information reaching a given Tor user, by analyzing the traffic patterns of encrypted data passing through a single computer in the all-volunteer Tor network.

Printed electronics for smart packaging project launched to increase value, unlock new markets for industry

Wed, 07/29/2015 - 15:38
Printed Electronics is key in enabling smart packaging innovations, a fast growing market for industry, researchers say. The smart packaging market is expected to grow to more than US$ 1.45 billion in the next decade, they note.

Shop-floor monitoring goes high tech

Wed, 07/29/2015 - 15:38
An advanced system based on discrete events paves the way for automated industrial monitoring. This system will enable managers to make better, more timely decisions, the developers say.

First smartphone DNA test for chlamydia

Wed, 07/29/2015 - 15:08
Researchers have developed a smartphone test for chlamydia that can detect the disease with high accuracy, which could reduce the prevalence of this sexually transmitted disease (STD) by making chlamydia screening easier and cheaper.

Tailored mobile health technologies may help patients take their medications appropriately

Tue, 07/28/2015 - 23:49
There was only a 5 percent error rate when patients with chronic kidney disease used mobile health technologies designed to help them use medications appropriately.

Big data gives new insight into blood pressure reduction role of commonly prescribed drug

Tue, 07/28/2015 - 20:52
A drug commonly prescribed to conserve potassium in the blood also significantly lowers blood pressure when taken in conjunction with a diuretic frequently prescribed to patients with hypertension, a new big data study has found. The combination of the two drugs, both available as generics, has been shown to consistently amplify the blood pressure reduction in patients with or without the presence of other antihypertensive agents such as ACE inhibitors and calcium channel blockers.
