A simple change in the choice of grass varieties for lawns of St. Augustinegrass could be a key tool for fending off fall armyworm infestations, according to new research. While no single St. Augustinegrass cultivar rises above the rest in resisting infestation, mixing varieties may confer some benefits, as fall armyworms clearly preferred single-cultivar plantings in a series of lab tests.
A new study reveals that many people with cancer use marijuana, and rates of use in the US have increased over time. The study also found that patients with cancer are more likely to use prescription opioids than adults without cancer.
A pair of researchers describes a way of making a submicron-sized cylinder disappear without using any specialized coating. Their findings could enable invisibility of natural materials at optical frequency and eventually lead to a simpler way of enhancing optoelectronic devices, including sensing and communication technologies.
In a small study of patients, researchers report that about half the people referred to the clinic with a schizophrenia diagnosis didn't actually have schizophrenia. Schizophrenia is a chronic, severe and disabling disorder marked by disordered thinking, feelings and behavior. People who reported hearing voices or having anxiety were the ones more likely to be misdiagnosed.
A team of astronomers from the United Kingdom and Germany has spotted a superflare coming from an L-dwarf star approximately 250 light-years away that’s estimated to be 10 times more powerful than any such event emitted by the Sun. L-dwarf stars are among the lowest mass objects that could still be considered to be a [...]
Modular -- or cliquey -- group structure isolates the flow of communication between individuals, which might seem counterproductive to survival. But for some animal groups, formation isn't necessarily better, according to new research.
Researchers at Tokyo Tech have revealed that an artificial receptor preferentially binds male steroid hormones from a mixture of male and female hormones in water. Based on their findings, they succeeded in the preparation of a prototype detection system for male hormones at the nanogram level. This achievement could lead to the development of ultrasensitive analytical devices for medical diagnostics and anti-doping testing in sports.
There are a few things that will result in poor customer reviews of a restaurant: bad service, bad food -- and bad weather. A study of 32 Florida restaurants found that customers left more negative remarks on comment cards on days when it was raining than on days when it was dry.
Archaeological excavation has, historically, operated in a very hierarchical structure, according to archaeologist. The history of the enterprise is deeply entangled with Western colonial and imperial pursuits, she says. Excavations have been, and often still are, led by foreigners from the West, while dependent on the labor of scores of people from the local community to perform the manual labor of the dig.
In 2015, about half of the world's 28 million human deaths were the result of medical emergencies, with the bulk of the burden borne by poorer nations, according to a statistical analysis of information from nearly 200 countries.
