Study finds variation within species plays critical role in health of ecosystems

Eurekalert - 23 hours 34 min ago
Concerns about biodiversity tend to focus on the loss of species, but a new study suggests that the loss of variation within species can also have important and unexpected consequences on the environment.

Patient satisfaction, caregiver communication can reduce risk of hospital readmission

Eurekalert - 23 hours 34 min ago
A survey of patients admitted to Massachusetts General Hospital (MGH) has found that patients reporting greater levels of satisfaction with their care and good communication with the health care providers were significantly less like to readmitted to the hospital in the 30 days after discharge.

Poll: Younger women, college educated women more likely to say they have been harassed

Eurekalert - 23 hours 34 min ago
This report is part of a series titled "Discrimination in America." The series is based on a survey conducted for National Public Radio, the Robert Wood Johnson Foundation, and Harvard T.H. Chan School of Public Health. While many surveys have explored Americans' beliefs about discrimination, this survey asks people about their own personal experiences with discrimination.

Artificial intelligence and supercomputers to help alleviate urban traffic problems

Eurekalert - 23 hours 34 min ago
Researchers from the University of Texas at Austin and the City of Austin have developed a tool that uses artificial intelligence to recognize objects in raw traffic camera footage and characterize how those objects move and interact. This information can then be analyzed and queried by traffic engineers and officials to improve the safety and performance of the city's transportation network. The work will be presented at the IEEE Big Data conference this week.

Multi-year submarine-canyon study challenges textbook theories about turbidity currents

Eurekalert - 23 hours 34 min ago
At the Fall 2017 meeting of the American Geophysical Union, scientists from around the world will present 19 talks and posters about the Coordinated Canyon Experiment -- the most extensive, long-term effort to monitor turbidity currents ever attempted. The results of this two-year project challenge existing paradigms about what causes turbidity currents, what they look like, and how they work.

Scientists identify promising new approach for immune system defense against cancer

Eurekalert - 23 hours 34 min ago
Researchers have identified a promising new strategy to fight infections and cancer. They uncovered a novel function for a protein known as 'Runx3' that is key to the development of killer T cells -- immune cells important for fighting infections and cancer. The researchers believe Runx3, if properly directed, could be combined with other approaches to help T cells recognize and destroy tumor cells and enhance vaccine efficacy.

Medicaid expansion popular among Americans connected to program

Eurekalert - 23 hours 34 min ago
A concerted effort by Republicans in Congress to repeal and replace the Affordable Care Act hit a surprising road block earlier this year: strong pushback against cuts to Medicaid. According to new findings from researchers at the University of Chicago, Medicaid is now seen as an important part of the middle-class social safety net, thanks to nearly 60 percent of Americans being connected to the program directly or through a family member or close friend.

AGU Fall Meeting: New simulations suggest meteors explode from the inside

Eurekalert - 23 hours 34 min ago
Researchers have identified an explosive new mechanism that breaks down meteors as they hurtle toward Earth. New simulations of falling meteors suggest air particles penetrate the space rocks' porous interiors as they careen through the atmosphere. These air particles create pockets of high pressure that ultimately lead the rock to explode from the inside, tens of kilometers above the Earth.

Study: Too many nutrients make microbes less responsive

Eurekalert - 23 hours 34 min ago
Bacteria in lakes play a key role in maintaining water quality by absorbing excess nitrogen and phosphorus. They also help store carbon, which has implications for our climate. But, as it turns out, their ability to do these tasks varies depending on the makeup of the lake in which they live, according to a new study by University of Minnesota researchers that was funded by the National Science Foundation. In short, location matters most.

New statistical method links vast records, shows negative effect of Texas voter ID law

Eurekalert - 23 hours 34 min ago
As state voter identification (ID) laws across the country are being contested amid questions about the integrity of the voting process, researchers have developed a new statistical method that not only matches multiple records with precision, but can also identify the scope of discrimination when applied to voter ID laws.

Managing concerning behaviors when opioids are taken for chronic pain

Eurekalert - 23 hours 34 min ago
Patients receiving long-term opioid therapy for chronic pain sometimes demonstrate challenging and concerning behaviors, such as using more opioid medication than prescribed or concomitant alcohol or drug use. A new study, published in the Journal of General Internal Medicine, establishes expert consensus about treatment approaches that should be implemented when these behaviors arise.

Presurgical imaging may predict whether epilepsy surgery will work

Eurekalert - 23 hours 34 min ago
A statistical approach to combining presurgical PET scans and functional MRI of the brain may help predict which patients with drug-resistant epilepsy are most likely to benefit from surgery. The method was developed by researchers at Rice University, Baylor College of Medicine, the University of California at Irvine and UCLA.

Discovery sets new world standard in nano generators

Eurekalert - 23 hours 34 min ago
A team of University of Alberta engineers has developed a new way to produce electrical power that can charge handheld devices or sensors that monitor anything from pipelines to medical implants.The discovery sets a new world standard in triboelectric nanogenerators by producing a high-density DC current--a vast improvement over low-quality AC currents produced by other research teams. The devices can transform mechanical energy such as wind or vibrations into electricity.

Tumors heat up

Eurekalert - 23 hours 34 min ago
Nanorods made of bismuth sulfide kill tumor cells with heat when they are irradiated with near-infrared light (NIR). Chinese scientists are now making these weapons more powerful by remodeling the defect state of the nanorod crystal lattice by adding gold nanodots. As reported in the journal Angewandte Chemie, this could be a good basis for more effective photothermal treatment of tumors.
