Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates.
When scientists discovered a worm deep in an aquifer nearly one mile underground, they hailed it as the discovery of the deepest-living animal ever found. Now American University researchers, reporting in Nature Communications, have sequenced the genome of the unique animal, referred to as the 'Devil Worm' for its ability to survive in harsh, subsurface conditions. The Devil Worm's genome provides clues to how an organism adapts to lethal environmental conditions.
The research result has been published in the journal Optics Letters recently.
Activities of neurons are generally completed on a time scale of 10 milliseconds, which makes it hard for conventional microscopes to observe these phenomena directly. This new compressive sensing two-photon microscopy can be applied to 3D imaging of the nerve distribution of living things or to monitoring activities from hundreds of neurons simultaneously.
New multi-focus laser scanning method to break the scanning speed limit of two-photon microscope
COLUMBUS, Ohio - The world's love for chocolate has helped decimate protected forests in western Africa as some residents have turned protected areas into illegal cocoa farms and hunting grounds.
But an international group of researchers has found that simply patrolling the grounds of two forest reserves in Ivory Coast has helped reduce illegal activity by well more than half between 2012 and 2016.
Vehicles moving at hypersonic speeds are bombarded with ice crystals and dust particles in the surrounding atmosphere, making the surface material vulnerable to damage such as erosion and sputtering with each tiny collision. Researchers at the University of Illinois at Urbana-Champaign studied this interaction one molecule at a time to understand the processes, then scaled up the data to make it compatible with simulations that require a larger scale.
For the little brown bat - a small mouse-eared bat with glossy brown fur - a warm, dry place to roost is essential to the species' survival. Reproductive females huddle their small furry bodies together to save thermal energy during maternity season (summer), forming "maternity colonies." In the face of severe population losses across North America, summer access to an attic or other permanent sheltered structure, as opposed to just trees or rock crevices, is a huge benefit to these bats.
"I'm so bored!" It's a typical complaint by teens in every era, but one that's growing more common for U.S. adolescents, especially girls.
New research at Washington State University has found that boredom is rising year after year for teens in 8th, 10th, and 12th grades, with greater increases for girls than boys.
"We were surprised to see that boredom is increasing at a more rapid pace for girls than boys across all grades," said Elizabeth Weybright, WSU researcher of adolescent development, who shared the findings in the Journal of Adolescent Health.
Hand-dug trenches around Leigh Lake in Grand Teton National Park in Wyoming reveal evidence for a previously unknown surface-faulting earthquake in along the Teton Fault--one occurring about 10,000 years ago.
Genetically targeted drugs and immunotherapies are transforming the way we treat many forms of lung cancer. However, a University of Colorado Cancer Center study published in the Journal of the National Cancer Institute shows that while the use of these drugs rose 27 percent from 2007 to 2015, new, high-cost lung cancer drugs are not used equally in all places, with all patients. Patients who lived in high-poverty areas were 4 percent less likely to be treated with high-cost lung cancer drugs.
The liver performs several critical functions including filtering blood, detoxifying chemicals and metabolizing drugs. When the liver is damaged by hepatitis, alcohol, or primary liver disease, fibrosis ensues. Long-term fibrosis contributes to cirrhosis of the liver, which in turn can cause severe complications, including hepatic encephalopathy (HE), a condition that results in a temporary decline in mental function in up to 70% of patients with cirrhosis.
