A new mathematical model that predicts which choices people will make in the Iowa Gambling Task, a task used for the past 25 years to study decision-making, outperforms previously developed models.

Early-season hurricanes result in greater transmission of mosquito-borne infectious disease

Posted: 13 Jun 2019 10:37 AM PDT

The timing of a hurricane is one of the primary factors influencing its impact on the spread of mosquito-borne infectious diseases such as West Nile Virus, dengue, chikungunya and Zika, according to new research.

Earth's heavy metals result of supernova explosion, research reveals

Posted: 13 Jun 2019 09:10 AM PDT

New research suggests most of Earth's heavy metals were spewed from a largely overlooked kind of star explosion called a collapsar.

NASA's Fermi mission reveals its highest-energy gamma-ray bursts

Posted: 13 Jun 2019 09:10 AM PDT

For 10 years, NASA's Fermi Gamma-ray Space Telescope has scanned the sky for gamma-ray bursts (GRBs), the universe's most luminous explosions. A new catalog of the highest-energy blasts provides scientists with fresh insights into how they work.

Concert of magnetic moments

Posted: 13 Jun 2019 09:10 AM PDT

Researchers have uncovered a new way how the electron spins in layered materials can interact.

Genes for Good project harnesses Facebook to reach larger, more diverse groups of people

Posted: 13 Jun 2019 09:10 AM PDT

The Genes for Good project has engaged more than 80,000 Facebook users, collected 27,000 DNA spit-kits, and amassed a trove of health survey data on a more diverse group of participants than has previously been possible.

Liquid gold on the nanoscale

Posted: 13 Jun 2019 09:10 AM PDT

Researchers have discovered what liquid gold looks like on the nanoscale -- and in doing so have mapped the way in which nanoparticles melt, which is relevant to the manufacturing and performance of nanotech devices.

The whisper of schizophrenia: Machine learning finds 'sound' words predict psychosis

Posted: 13 Jun 2019 07:45 AM PDT

Automated analysis of the two language variables -- more frequent use of words associated with sound and speaking with low semantic density, or vagueness -- can predict whether an at-risk person will later develop psychosis with 93 percent accuracy.

Bitcoin causing carbon dioxide emissions comparable to Las Vegas or Hamburg

Posted: 13 Jun 2019 07:45 AM PDT

The use of Bitcoin causes around 22 megatons in carbon dioxide emissions annually -- comparable to the total emissions of cities such as Las Vegas or Hamburg.

Carbon-neutral fuel made from sunlight and air

Posted: 13 Jun 2019 07:31 AM PDT

Researchers have developed a novel technology that produces liquid hydrocarbon fuels exclusively from sunlight and air. For the first time worldwide they demonstrate the entire thermochemical process chain under real field conditions.

New quantum dot microscope shows electric potentials of individual atoms

Posted: 13 Jun 2019 07:31 AM PDT

Researchers have developed a new method to measure the electric potentials of a sample at atomic accuracy. The new scanning quantum dot microscopy method could open up new opportunities for chip manufacture or the characterization of biomolecules such as DNA.

People with mobility issues set to benefit from wearable devices

Posted: 13 Jun 2019 07:31 AM PDT

Researchers are working on a project to develop wearable rehabilitative devices that can help disabled people sit, stand and walk in comfort.

'Virtual biopsy' device to detect skin tumors

Posted: 13 Jun 2019 07:31 AM PDT

Using sound vibrations and pulses of near-infrared light, a scientist has developed a new 'virtual biopsy' device that can quickly determine a skin lesion's depth and potential malignancy without using a scalpel.

Making the 'human-body Internet' more effective

Posted: 13 Jun 2019 06:52 AM PDT

Human body communication (HBC) uses the human body to transmit power and data, much like the internet. Because it's a smaller and closed network, it has the benefit of being more secure and power efficient. In a recent study, a group of Japanese researchers used an equivalent circuit model to examine how different parameters affect HBC transmission characteristics.

Financial vulnerability may discourage positive negotiation strategies

Posted: 13 Jun 2019 06:52 AM PDT

People who feel financially vulnerable may be prone to believing incorrectly their success in negotiations must come at the expense of the other party, leading them to ignore the potential for more cooperative and mutually beneficial options.
