Tokyo, Japan - Biliary tract cancer is a type of cancer that occurs in the bile ducts, which transport bile from the liver to the duodenum. While generally rare, these cancers are relatively common in Asian populations. Patients with one form of this cancer, called intrahepatic cholangiocarcinoma (ICC), have very poor outcomes and rarely survive beyond five years after their diagnosis.
In a new paper, researchers at North Carolina State University lift the veil on the "conductor" plant root stem cell gene that helps orchestrate and coordinate stem cell division of different root stem cell types, ensuring the harmonic communication necessary for plant growth and maintenance.
The researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) and Institute of Problems of Mechanical Engineering of the Russian Academy of Sciences studied the distribution of hydrogen in metals in the process of standard testing for hydrogen cracking. They found that there is a surface effect that does not let hydrogen enter the metal. This can result in errors in industrial quality control of material, and to fundamental errors in terms of scientific research of hydrogen embrittlement.
CAMDEN - Formerly incarcerated individuals with barriers to re-entry and service needs following their release are subsequently more likely to experience poor physical and mental health, according to an eye-opening new Rutgers University-Camden study.
UT Health San Antonio researchers, working with collaborators at the University of Florida, have discovered a safe and potent next generation of drugs to fight multiple types of leukemia and lymphoma in adults and children. The journal Nature Medicine reported the findings Dec. 2.
New research by scientists at Harvard Medical School has found that nerves in the guts of mice do not merely sense the presence of Salmonella but actively protect against infection by this dangerous bacterium by deploying two lines of defense.
CORVALLIS, Ore. - Animals that evolved in environments subject to large-scale habitat-altering events like fires and storms are better equipped to handle forest fragmentation caused by human development than species in low-disturbance environments, new research shows.
Oregon State University scientists led an international collaboration whose work provides an important road map as conservation managers consider the effects of forest edges on wildlife in setting up reserves.
Findings of the study were published today in Science.
A new technique reported in Science this week overcomes several limitations of typical high-throughput chemical screens conducted on cell samples. Such screens are commonly used to try to discover new cancer drugs, and in many other biomedical applications.
Most current screens of this nature offer either a coarse readout, such as of cell survival, proliferation or alterations in cell shapes, or only a specific molecular finding, such as testing whether a particular enzyme is blocked.
Placing lights on fishing nets reduces the chances of sea turtles and dolphins being caught by accident, new research shows.
LED lights along the top of floating gillnets cut accidental "bycatch" of sea turtles by more than 70%, and that of small cetaceans (including dolphins and porpoises) by more than 66%.
A joint research team led by MAO Fangyuan from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences and MENG Jin from the American Museum of Natural History reported a new symmetrodont, Origolestes lii, a stem therian mammal from the Early Cretaceous Jehol Biota, in China's Liaoning Province.
According to a much-debated geo-engineering approach, both sea-ice retreat and global warming could be slowed by using millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter. AWI researchers have now, for the first time, tested the concept using a complex climate model and published their findings in the journal Earth's Future.
TALLAHASSEE, Fla. -- A team of Florida State University researchers studying new methods to remove toxic heavy metals from biosolids -- the solid waste left over after sewage treatment -- found the key is a brief spin through a microwave.
The interaction between light and matter is the basis of both many fundamental phenomena and various practical technologies. Most famously, in the photoelectric effect, electrons are emitted from a material that is exposed to light of suitable energy. For long, the origin of the phenomenon remained a riddle, and only with the advent of quantum theory -- and thanks to the genius of Albert Einstein -- was the effect fully understood.
From early story concepts to a theatrical release, full-length animated films can take years to create. One of the biggest time commitments comes during the animation process when the animators are simulating fluid materials, like water or hair.
Think about the Disney character Elsa in the film "Frozen 2" as she is running across the ocean and turning water into ice.
That simulation process can take more than a day to compute for one scene and is very costly. For filmmakers, it's also hard to nail down a perfect scene on the first try.
NASA-NOAA's Suomi NPP satellite passed over the Arabian Sea and captured a visible image of Tropical Storm 06A, now renamed Tropical Storm Pawan.
