The Rice University think tank aims to recycle carbon dioxide into useful products, partnering with energy companies to make carbon a profitable resource. Strategies include repurposing CO2 as a feedstock for chemicals or sequestering it in oil wells.
Astronomers using space telescopes have discovered a previously unknown brilliant X-ray explosion in the Milky Way galaxy, named MAXI J1409-619. The object, a binary system, was revealed to be emitting massive blasts of X-rays after being detected by an instrument on the International Space Station.
A Swiss study by Empa found that energy-saving lamps have a larger ecological footprint due to electronic circuitry, but recycling reduces environmental effects. The production of incandescent bulbs has a negligible impact on the environment, while usage and power source are major factors.
The National Science Foundation has recognized three projects with Breakthrough Awards: an artificial retina restoring sight to the blind; a system using controlled rocking to help buildings withstand earthquakes; and a low-cost medical microscope for detecting malaria-infected blood cells.
Researchers at Penn State College of Medicine have identified a potential new treatment approach targeting the protein c-Met in patients with metastatic liver cancer. By analyzing data from 1,051 patients and six published manuscripts, they found that c-Met activation is strongly associated with poor prognosis and aggressive features. ...
The researchers aim to understand how animals, including humans, quickly adjust to unexpected events. By studying the sea slug's ability to adjust its eating behavior, they hope to develop mathematical models that can predict how patterns of activity in the nervous system change over time.
Physicists and engineers have installed a radar system on the Falkland Islands to monitor upper atmosphere activity that creates the Southern Lights. The radar station, part of the international Super Dual Auroral Radar Network, will help climatologists understand the link between the upper and lower atmospheres.
A UT professor's study found that economic inequality increases both the rich and poor becoming more conservative, reducing support for government programs. The study analyzed hundreds of thousands of survey responses from 1952 to 2006, revealing a self-perpetuating phenomenon.
Parents of children with cancer reported feeling hurried and less well-informed about clinical trial protocols compared to adult patients. The study found that parents felt they had insufficient time to learn about the trials and asked fewer questions.
A recent study found that total health care expenditures for children with autism spectrum disorders (ASDs) per 10,000 covered lives grew by 32.8% from $1,270,435 in 2000 to $1,686,938 in 2003. The treated prevalence of autism increased by 32.2% during the same period.
Typhoon Megi is forecast to make landfall in southeastern China late at night on October 22 as a Category One typhoon. NASA satellites have been monitoring the storm's rainfall, changing cloud cover, and weakening eye, which weakened due to wind shear.
A new meta-analysis study by Syracuse University Professor Stephanie Ortigue found that falling in love affects intellectual areas of the brain and releases euphoria-inducing chemicals. The study revealed that love can be sparked by different parts of the brain, including those involved in mental representation, metaphors, and body image.
Tropical Storm Richard is expected to intensify in the western Caribbean before making landfall, bringing maximum storm totals of 5-7 inches of rain and potentially flash flooding and mudslides.
