‘Google Maps’ for Cancer: Image-Based Computer Model Reveals Finer Details of Tumor Blood Flow Behavior

Johns Hopkins Medicine

Johns Hopkins Medicine researchers say they have developed something akin to a “Google Maps” approach for more accurately computing and visualizing the structural and functional blood vessel changes needed for tumor growth. By pairing high-quality 3D imaging data of tumor specimens from animal models with sophisticated mathematical formulas, the researchers say they now have a model that accurately represents blood traffic inside tumors, including the complex blood flow, oxygenation and structural changes that occur.

Fifteen years of mosquito data implicate species most likely to transmit West Nile virus in Iowa

Iowa State University

A study published this week that analyzed 15 years of mosquito surveillance data shows Iowa’s western counties experience a higher abundance of the species thought to most commonly carry West Nile virus. Culex tarsalis, the mosquito species most often implicated in West Nile transmission, usually becomes most active in early September. The data support similar findings in Nebraska and South Dakota.

N.C. Study: Warmer Water Linked to Higher Proportion of Male Flounder

North Carolina State University

In the wild and in the lab, researchers find a relationship between higher water temperatures and a lower percentage of female flounder, a cause for concern.

Cool Tool Could Enable Quantum Computers to Tackle More Complex Applications

Johns Hopkins University Applied Physics Laboratory

In a paper published in Nature Scientific Reports, APL researchers describe a way to manipulate the critical elements of a quantum computer and their control components that will be an important piece of scaling quantum computer systems to the larger sizes needed for more complex applications.

New Lens System for Brighter, Sharper Diffraction Images

Brookhaven National Laboratory

To design and improve energy storage materials, smart devices, and many more technologies, researchers need to understand their hidden structure and chemistry. Advanced research techniques, such as ultra-fast electron diffraction imaging can reveal that information. Now, a group of researchers from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have developed a new and improved version of electron diffraction at Brookhaven’s Accelerator Test Facility (ATF)—a DOE Office of Science User Facility that offers advanced and unique experimental instrumentation for studying particle acceleration to researchers from all around the world.

Simple sea anemones not so simple after all

Ohio State University

Researchers, including a team from The Ohio State University, have published new findings showing that the DNA of the tube anemone does what few other species’ mitochondrial genomes have been shown to do. It defies the classic doughnut shape it “should” be in and is arranged in several fragmented pieces, the number of which vary depending on the species. On top of that, the animal now holds the record for the largest mitochondrial genome reported to date. It contains almost 81,000 base pairs, or pieces of genetic information, according to the new study, published online in the journal Scientific Reports. Human mitochondrial DNA contains fewer than 17,000 base pairs.
