Dinosaur embryo find helps crack baby tyrannosaur mystery — ScienceDaily
They are among the largest predators ever to walk the Earth, but experts have discovered that some baby tyrannosaurs were only the size of a Border Collie dog when they took their first steps. The first-known fossils of tyrannosaur embryos have shed light on the early development of the colossal animals, which could grow to […]
Researchers find how cells move while avoiding adhesion
Cancer cells moving on glycoproteine strips: These strips act like splints, which allow to control and to study the movement of the cells better. Credit: Rädler Lab, Ludwig Maximilians Universität München Cell velocity, or how fast a cell moves, is known to depend on how sticky the surface is beneath it, but the precise mechanisms […]
Researchers Find NTRK fusions more common than expected in pediatric tumors — ScienceDaily
In a large study of pediatric cancer patients, researchers from Children’s Hospital of Philadelphia (CHOP) have analyzed the frequency, fusion partners, and clinical outcome of neurotrophic tyrosine receptor kinase (NTRK) fusions, which are clinical biomarkers that identify patients suitable for treatment with FDA-approved TRK inhibitors. The researchers found that NTRK fusions are more common in […]
Engineers find a way to control chemical catalysts with sculpted light
Depiction of the experimental setup where palladium nanorods lie atop gold nanobars. In this image, an electron beam is directed at the sample to watch the catalytic interactions between the hydrogen molecules (in green) and the palladium catalyst. The light driving the illumination is shown in red. Credit: Katherine Sytwu Like a person breaking up […]
Researchers find wildfire smoke is more cooling on climate than computer models assume
The University of Wyoming Mobile Lab measures biomass burning smoke in Wyoming from a couple of years ago. This is an example of the type of field measurement that was used to compare with computer models. Credit: Rachel Edie A study of biomass burning aerosols led by University of Wyoming researchers revealed that smoke from […]
Researchers find nonnative species in Oahu play greater role in seed dispersal — ScienceDaily
University of Wyoming researchers headed a study that shows nonnative birds in Oahu, Hawaii, have taken over the role of seed dispersal networks on the island, with most of the seeds coming from nonnative plants. “Hawaii is one of the most altered ecosystems in the world, and we are lucky enough to examine how these […]
Researchers find nonnative species in oahu play greater role in seed dispersal networks
Corey Tarwater (right), an assistant professor in the University of Wyoming Department of Zoology and Physiology, and Becky Wilcox, a UW Ph.D. student at the time of the research from Napa, Calif., set up automated radio telemetry units to track birds in Oahu, Hawaii. Tarwater and members of her research team headed research on how […]
Metastable metallic nanoparticles could find use in electronics, optics
Rice University scientists extended their technique to produce graphene in a flash to tailor the properties of 2D dichalcogenides molybdenum disulfide and tungsten disulfide, quickly turning them into metastable metallics for electronic and optical applications.

Engineers find antioxidants improve nanoscale visualization of polymers — ScienceDaily
Reactive molecules, such as free radicals, can be produced in the body after exposure to certain environments or substances and go on to cause cell damage. Antioxidants can minimize this damage by interacting with the radicals before they affect cells. Led by Enrique Gomez, professor of chemical engineering and materials science and engineering, Penn State […]
Mexican farmers find rare female statue in citrus grove
In this Jan. 4, 2021 photo released by Mexico’s National Institute of Anthropology, known by its Spanish acronym INAH, the statue of a female figure unearthed in Hidalgo Amajac, is seen in nearby Alamo Temapache, Veracruz state, Mexico. Farmers digging in a citrus grove on New Year’s Day found the six-foot tall statue of a […]
