Researchers have identified a single genetic alteration in a malaria-transmitting mosquito species that confers resistance to a widely used insecticide, according to a new study.
Using data from computed tomography (CT) images, researchers may be able to predict which lung cancer patients will respond to chemotherapy, according to a new study.
A team of scientists led by Alida Bailleul and Jingmai O'Connor from the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences reported the first fossil bird ever found with an egg preserved inside its body. This new Cretaceous fossil sheds light on avian reproduction.
With the release of youth football-helmet ratings by the Virginia Tech Helmet Lab -- already renowned for their helmet ratings for varsity football and other sports -- consumers can see which helmets best reduce concussion risk.
Risks of death from heart disease and stroke vary among American-Asian subgroups, with Asian Indian, Filipino and Vietnamese populations at greatest risk for losing years of life to heart disease or stroke. All Asians had higher years of life lost to stroke than non-Hispanic whites.
Parkinson's disease is a neurodegenerative disorder that leads to progressive brain cell death and extensive loss of motor function. Despite much research being conducted on this disease, there are no definitive diagnostic tests currently available. Now, researchers report the identification of compounds that make up the signature odor of the disease with the help an individual who can detect Parkinson's through smell. They report their findings in ACS Central Science.
Modern analytical tools like mass spectrometers can identify many unknown substances, allowing scientists to easily tell whether foods or medicines have been altered. However, the cost, size, power consumption and complexity of these instruments often prevent their use in resource-limited regions. Now, in ACS Central Science, researchers report that they have developed a simple, inexpensive method to identify samples by seeing how they react to a change in their environment.
Irrigation water's E. coli results can differ between labs, test types.
A new species of Surazomus, which belongs to the class Arachnida and the order Schizomida, has been discovered in the eastern Amazon, according to a study published March 20 in the open-access journal PLOS ONE by Gustavo Ruiz and Roberta Valente of the Universidade Federal do Pará in Brazil.
The scientists analyzed data spanning more than four decades and concluded that the impact of lake trout in Yellowstone Lake -- in particular, the decline of native cutthroat trout -- has cascaded across the lake, its tributaries and the surrounding ecosystem.
