Space technologies improve surgeries back on earth

Sat, 22/04/2017 - 2:20pm
A novel surgical robotic system has been developed that provides tactile feedback and is capable of single-incision and natural orifice (incision-free) robotic surgery. The system minimizes surgical trauma and is safer than currently available robotic systems.

Cold weather, fewer sun hours are associated with increased rates of alcoholic cirrhosis

Sat, 22/04/2017 - 2:16pm
Colder and less sunny regions of the world have higher rates of alcoholic cirrhosis, a disease caused by excessive drinking which results in irreversible scarring of the liver, new research shows. An international team of scientists found that every increase in temperature of one degree Celsius was linked with a decrease in the alcohol-attributable fraction of cirrhosis of 0.3 percent.

Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Sat, 22/04/2017 - 1:08am
Reflecting the structure of composites found in nature and the ancient world, researchers have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

Forces that threaten sensitive coastlines

Sat, 22/04/2017 - 1:08am
Wind-driven expansion of marsh ponds on the Mississippi River Delta is a significant factor in the loss of crucial land in the Delta region, according to new research. The study found that 17 percent of land loss in the area resulted from pond expansion, much of it caused by waves that eroded away the edges of the pond.

Data analysis finds lower risk of infection with LASIK than with contacts over time

Sat, 22/04/2017 - 1:08am
A meta-data analysis comparing the incidence of microbial keratitis, an infection of the cornea caused by bacteria or a virus, for contact lens wearers versus post-LASIK (laser-assisted in situ keratomileusis) patients indicates that over time the infection rate for the contact lens wearers was higher than for those who had LASIK to correct their vision.

Promising mouse model for a devastating genetic deficiency

Fri, 21/04/2017 - 7:02pm
A potential mouse model for the genetic disorder known as an NGLY1 deficiency has been developed by scientists. Their new study describes how a second knockout produces mice that survive after birth and have symptoms that are analogous to humans with NGLY1-deficiency.

New discovery could aid in detecting nuclear threats

Fri, 21/04/2017 - 4:33pm
A new way to detect nuclear materials has been developed by researchers. Made of graphene and carbon nanotubes, the researchers' detector far outpaces any existing one in its ultrasensitivity to charged particles, minuscule size, low-power requirements, and low cost.

Making bins more convenient boosts recycling and composting rates

Fri, 21/04/2017 - 4:32pm
Want to recycle or compost more? Try moving the bins closer, new research suggests. The study shows that placing bins 1.5 meters away from suite doors drastically boosts recycling and composting rates by 141 per cent. The findings highlight how small changes in convenience can have a big impact on performance.

New survey: Snapchat and Instagram are most popular social media platforms among American teens

Fri, 21/04/2017 - 3:33pm
A new nationally representative survey of American teenagers age 13-17 finds that teens have shifted their favored social media platforms and are now most likely to use Instagram and Snapchat. The study also found that while almost all teens -- 91 percent -- use the regular text messaging tool on their mobile phones, 40 percent of teens also use messaging applications like Kik, WhatsApp, or Line on a smartphone.

Weight expectations: Context and distraction skew what we predict and remember

Fri, 21/04/2017 - 3:32pm
Context can alter something as basic as our ability to estimate the weights of simple objects. As we learn to manipulate those objects, context can even tease out the interplay of two memory systems and shows how distraction can affect multitasking.

Plant's parent genes cooperate in shaping their child

Fri, 21/04/2017 - 2:37pm
Plant biologists discovered for the first time how factors arising from the mother and father in flowering plants cooperate to develop the shape of their child. Until now, it has been unknown whether paternal factors cooperate or conflict with each other to bring about zygote asymmetry. The outcome of this discovery is expected to shed light on the exact mechanism of plant body shape formation and possibly lead to the generation of new hybrid plants.
