WhatsApp use by Argentina ambulances associated with faster heart attack treatment

Mié, 10/18/2017 - 22:00
WhatsApp use by ambulance doctors in Argentina was associated with faster treatment of heart attack and lower mortality in an observational study presented today at the Argentine Congress of Cardiology (SAC 2017). The free messaging application was used to send diagnostic electrocardiograms (ECGs) directly to hospital catheterisation (cath) laboratories, enabling patients to bypass the emergency department.

Lower brain glucose levels found in people with obesity, type 2 diabetes

Mié, 10/18/2017 - 22:00
Glucose levels are reduced in the brains of individuals with obesity and type 2 diabetes compared to lean individuals, according to a new Yale study. The finding might explain disordered eating behavior -- and even a higher risk of Alzheimer's disease -- among obese and diabetic individuals, the researchers said.

Scientists pinpoint jealousy in the monogamous mind

Mié, 10/18/2017 - 22:00
Scientists find that in male titi monkeys, jealousy is associated with heightened activity in the cingulate cortex, an area of the brain associated with social pain in humans, and the lateral septum, associated with pair bond formation in primates. A better understanding of jealousy may provide important clues on how to approach health and welfare problems such as addiction and domestic violence, as well as autism.

Phenogenetic map created for stem cells models of neurological diseases

Mié, 10/18/2017 - 22:00
In an effort to better understand neurological diseases like Alzheimer's, Parkinson's and ALS -- and develop new ways to treat them -- researchers at The Ohio State University Wexner Medical Center have performed the first meta-analysis of all induced pluripotent stem cell models for neurological and neurodegenerative diseases, and created an atlas of how cell characteristics are linked to their genotype.

Researchers demonstrate new ways to achieve selectivity for biomarkers in bioelectronics

Mié, 10/18/2017 - 22:00
Two UA materials science and engineering researchers have experimentally verified the electrochemical processes that control charge transfer rate from an organic polymer to a biomarker molecule. Their findings, reported in Nature Communications, may enhance selectivity for biomarkers in bioelectronic devices.

Fossil coral reefs show sea level rose in bursts during last warming

Mié, 10/18/2017 - 22:00
Scientists from Rice University and Texas A&M University-Corpus Christi's Harte Research Institute have discovered that Earth's sea level did not rise steadily when the planet's glaciers last melted during a period of global warming; rather, sea level rose sharply in punctuated bursts.

New technology to dramatically speed up home broadband

Mié, 10/18/2017 - 22:00
Slow internet speeds and the Internet 'rush hour' -- the peak time when data speeds drop by up to 30 percent -- could be history with new hardware designed and demonstrated by UCL researchers that provides consistently high-speed broadband connectivity.

How a neutron star collision proves Einstein's 100-year-old General Relativity prediction

Mié, 10/18/2017 - 22:00
A hundred years ago, Albert Einstein published his General Relativity theory, predicting the existence of gravitational waves or ripples in space-time, due to violent motion of massive objects in the universe. Collision and merger of two neutron stars should produce gravitational waves and gamma rays simultaneously. Until a few weeks ago, that could not be proven scientifically. Then researchers saw the collision of two neutron stars on Aug. 17, 2017, and everything changed.

IDSA Infectious Diarrhea guidelines recommend when to test, when to treat

Mié, 10/18/2017 - 22:00
New tests provide more detailed information about organisms associated with infectious diarrhea, but may require infectious disease expertise to interpret them.

The best hedge fund managers are not psychopaths or narcissists, according to new study

Mié, 10/18/2017 - 22:00
When it comes to financial investments, hedge fund managers higher in 'dark triad' personality traits -- psychopathy, narcissism, and Machiavellianism -- perform more poorly than their peers, according to new personality psychology research. The difference is a little less than 1 percent annually compared to their peers, but with large investments over several years that slight underperformance can add up.

Ben-Gurion U. introduces israel's first underwater robotic vehicle

Mié, 10/18/2017 - 22:00
'The autonomous HydroCamel II integrates state-of-the-art technologies, including high-level maneuvering in six degrees of freedom and an ability to dive almost vertically,' says Prof. Hugo Guterman of the BGU Department of Electrical and Computer Engineering and head of LAR. 'Until now, these capabilities were limited to remotely operated underwater vehicles (ROVs), which must be tethered by an umbilical cable to a host ship for its power and air source. The HydroCamel II is completely autonomous.'

When new players learn slot-machine tricks, they avoid gambling addiction

Mié, 10/18/2017 - 22:00
Novice gamblers who watched a short video about how slot machines disguise losses as wins have a better chance of avoiding gambling problems, according to new research.

Integrated lab-on-a-chip uses smartphone to quickly detect multiple pathogens

Mié, 10/18/2017 - 22:00
A multidisciplinary group that includes the University of Illinois at Urbana-Champaign and the University of Washington at Tacoma has developed a novel platform to diagnose infectious disease at the point-of-care, using a smartphone as the detection instrument in conjunction with a test kit in the format of a credit card.

WSU researcher links salmon sex to geological change

Mié, 10/18/2017 - 22:00
It turns out that sex can move mountains.A Washington State University researcher has found that the mating habits of salmon can alter the profile of stream beds, affecting the evolution of an entire watershed. His studyis one of the first to quantitatively show that salmon can influence the shape of the land.
