WASHINGTON - Recent negative publicity surrounding police after several shootings of unarmed civilians appears to have diminished some officers' motivation to be in law enforcement but does not decrease willingness to carry out their duties, according to a study published by the American Psychological Association.

This week's issue of PLOS Medicine features two separate studies, each of which investigates the importance of uninterrupted piped water supplies to health outcomes. In a matched cohort study in Hubli-Dharwad, India, Ayse Ercumen of the University of California, Berkeley, and colleagues compared health outcomes for households that had been upgraded to receive continuous piped water to households with intermittent water supply.

A team of researchers from the Universities of Bristol and Sussex in collaboration with Ultrahaptics have built the world's first sonic tractor beam that can lift and move objects using sound waves.

Tractor beams are mysterious rays that can grab and lift objects. The concept has been used by science-fiction writers, and programmes like Star Trek, but has since come to fascinate scientists and engineers. Researchers have now built a working tractor beam that uses high-amplitude sound waves to generate an acoustic hologram which can pick up and move small objects.

October 27, 2015 - Some people with glaucoma-related binocular (both eyes) vision loss can pass a standard driving test by adopting increased visual scanning behavior, reports a study in the October issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.

Researchers in Manchester have used recent advances in PET scanning technology to reduce the radiation dose for both patients and staff by up to 30%, allowing an addition of an annual 100 scans a year at Central Manchester University Hospitals.

PET imaging is widely used in the management of cancer patients. Most commonly, an FDG PET scan is carried out to identify areas with high glucose metabolism, such as tumours. These images are useful for diagnosis, staging and monitoring treatment.

The discovery of artemisinin and its derivatives dramatically changes the landscape to combat malaria, and approximately 22% of the 663 million averted clinical cases were due to the use of artemisinin combination therapies (ACTs), according to a recent estimate. Artemisinin leads to two paradigm shifts in antimalarial research and therapy: one is the change from quinoline-based antimalarial drugs to artemisinin-based therapies, and the other is the change of research direction in antimalarial drug development.

Once an icon of overfishing, mismanagement, and stock decline, the northern Atlantic cod is showing signs of recovery according to new research published today in the Canadian Journal of Fisheries and Aquatic Sciences.

Fast Facts:

  • CT scans outperform stress tests in spotting clogged arteries.
  • CT angiograms detect blockages in nine out of 10 people.
  • Tests can miss four out of 10 patients with clogged heart vessels.

Results of a head-to-head comparison study led by Johns Hopkins researchers show that noninvasive CT scans of the heart's vessels are far better at spotting clogged arteries that can trigger a heart attack than the commonly prescribed exercise stress that most patients with chest pain undergo.

On the floor of the grave lay the skeleton of an adult male, stretched out on his back. Weapons lay to his left, and jewelry to his right.

Near the head and chest was a bronze sword, its ivory hilt covered in gold. A gold-hilted dagger lay beneath it. Still more weapons were found by the man's legs and feet.

DURHAM, N.C. -- When the largest modern-day plant-eaters -- elephants -- are confined to too small an area, they devastate the vegetation. So 15,000 years ago, when the herbivores like the Columbian mammoth, mastodons and giant ground sloths were even larger, more numerous and more widely distributed, how did the landscape survive?

The answer was probably enormous predators, creatures called "hypercarnivores" by a team of evolutionary biologists appearing online the week of Oct. 26 in the Proceedings of the National Academy of Sciences.

WASHINGTON -- Even when young women had a similar or greater risk for heart disease than young men, they were 11 percent less likely to report that healthcare providers told them they were at-risk for heart disease prior to a heart attack, according to a new study published today in the Journal of the American College of Cardiology.

Young women with ST-elevation myocardial infarction were less likely to receive life-saving angioplasty and stenting to restore blood flow to blocked arteries than men and also had longer hospital stays and higher rates of in-hospital mortality, according to a study published today in the Journal of the American College of Cardiology.

New Haven, Conn.--Only half of younger heart attack patients believed that they were at risk before the onset of an attack, and even fewer discussed health risks with their doctors, according to Yale School of Public Health researchers. The findings were more pronounced among women than men.
