A new study examined two classes of medications commonly prescribed to prevent cardiovascular events in dialysis patients and found no significant difference in outcomes.
In the retina of mice, a new type of neuron that falls outside century-old classifications has been discovered. The new cell acts like one class of neurons but anatomically resembles another. It is not only a new kind of neuron, but it also exhibits a new way of conveying information within the retina of the eye.
New research provides important clues that might help understand the resistance to drugs that 'starve' tumors, and also how cancer cells manage to survive in the center of the tumor mass, where barely any blood vessels can reach.
People who live in provinces with policies that allow pharmacists to administer influenza vaccines are more likely to be vaccinated, according to a new Canadian study.
For the first time in Brazil, a particular antibiotic resistance mechanism conferring resistance to the important antibiotic, colistin, has been detected in a human. It was in a strain of Escherichia coli that was isolated from a diabetic patient's foot infection. The mechanism, called MCR-1, was incorporated into a plasmid, a short piece of DNA that exists independent of the genome, which can jump from one bacterium to another, spreading the resistance.
Scientists have decoded the genome of Okinawa mozuku, a seaweed with healthy properties that plays a key economic and ecological role.
Scientists have identified a novel mechanism that selectively operates in hypoxic tumors to enable tumor cells to thrive and continue to proliferate despite a low oxygen environment. The research team showed how the activation of this pathway leads to an unfavorable prognosis for patients with gliomas – a type of brain tumor – and how the pathway could be a valuable therapeutic target in cancer.
Researchers are rethinking plant breeding strategies to improve the development of new high-yielding, stress-tolerant cereal varieties. They say small gene-regulating molecules found in plant cells (known as small RNA) are involved in stress adaptation, and they could be exploited to breed plants with favorable stress-tolerant traits.
Some horses have special gaits, which are more comfortable for the rider than walk, trot or gallop. Now, a study by an international research team has revealed that these gaited horses most likely originated in the 9th century medieval England. From there they were brought to Iceland by the Vikings and later spread all over Europe and Asia.
Accounting for ozone: Study first to quantify impact of oil and gas emissions on Denver's ozone problem
A new study is the first to directly quantify how emissions from oil and gas activities influence summertime ozone pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region's chronic ozone problem.
Scientists have announced an exciting new result that could improve our understanding of the behavior of neutrinos. Neutrinos have previously been detected in three types, called flavors - muon, tau and electron. They also exist in three mass states, but those states don't necessarily correspond directly to the three flavors.
How smart were human-like species of the Stone Age? New research reveals surprisingly sophisticated adaptations by early humans living 250,000 years ago in a former oasis near Azraq, Jordan.
Three types of functional coatings have been developed that are resistant to microorganisms and have self-cleaning and anti-reflective properties. By modifying the surface of paints he has managed to vary their properties or their possible applications at a lower cost in comparison with the materials existing on the market.
A new study challenges earlier interpretations of an important burial mound at Cahokia, a pre-Columbian city in Illinois near present-day St. Louis. The study reveals that a central feature of the mound, a plot known as the 'beaded burial,' is not a monument to male power, as was previously thought, but includes both males and females of high status.
An important step toward practical quantum computers has been made, with a new paper describing a prototype chip that can trap ions in an electric field and, with built-in optics, direct laser light toward each of them.
Most grade school students are likely to claim recess as their favorite period of the day; however, in many cases recess still can be sedentary with students not engaging in enough physical activity. Now researchers have found that zones with specific games can improve physical activity, improving a child's chance of engaging in the recommended 60 minutes of 'play per day,' an effort endorsed by many health organizations as well as the National Football League.
Older adults in assisted-living facilities experience limits to their rights to sexual freedom because of a lack of policies regarding the issue and the actions of staff and administrators at these facilities, according to research.
Chronic neuropathic pain -- caused by nerve damage as a result of an injury, surgery or a debilitating disease like diabetes or cancer -- could be greatly reduced in animals when the injury is treated targeting microglia brain cells within a few days, say scientists. This research will help in the quest to help the more than 1 million Americans afflicted with this chronic pain.
Working or volunteering can reduce the chances of chronic health conditions leading to physical disability in older Americans, according to researchers.
The estimated burden of cancer from environmental carcinogens is significant, particularly when compared to other known cancer risk factors. Between 3,540 and 6,510 new cancer cases in Ontario each year result from environmental factors, says a new report.
