UMD researchers identify structure of blue whirls
'Blue whirls' -- small, spinning blue flames that produce almost no soot when they burn -- have attracted great interest since their discovery in 2016, in part because they represent a potential new avenue for low-emission combustion. Now, a team of researchers has identified how these intriguing whirls are structured.

Systemic racism has consequences for all life in cities
Social inequalities, specifically racism and classism, are impacting the biodiversity, evolutionary shifts and ecological health of plants and animals in our cities. That's the main finding of a review paper published Aug. 13 in Science led by the University of Washington, with co-authors at the University of California, Berkeley, and University of Michigan.

A quick, cost-effective method to track the spread of COVID-19
A group of researchers have demonstrated that, from seven methods commonly used to test for viruses in untreated wastewater, an adsorption-extraction technique can most efficiently detect SARS-CoV-2. This gives us another tool to detect the presence and spread of the COVID-19 pandemic.

Flipping a metabolic switch to slow tumor growth
The enzyme serine palmitoyl-transferase can be used as a metabolically responsive "switch" that decreases tumor growth, according to a new study by a team of San Diego scientists, who published their findings Aug. 12 in the journal Nature. By restricting the dietary amino acids serine and glycine, or pharmacologically targeting the serine synthesis enzyme phosphoglycerate dehydrogenase, the team induced tumor cells to produce a toxic lipid that slows cancer progression in mice.

Molecular additives enhance mechanical properties of organic solar cell material
Ganesh Balasubramanian, P.C. Rossin assistant professor of Mechanical Engineering & Mechanics at Lehigh University, and his graduate student Joydeep Munshi demonstrated that adding small molecules to a semiconducting polymer blend enhances the performance and stability of material used in organic solar cells. The study is described in an article, 'Elasto-morphology of P3HT:PCBM bulk heterojunction organic solar cells' featured on the back cover of Soft Matter.

Nanocrystals from recycled wood waste make carbon-fiber composites tougher
In a new study, Texas A&M University researchers have used a natural plant product, called cellulose nanocrystals, to pin and coat carbon nanotubes uniformly onto the carbon-fiber composites. The researchers said their prescribed method is quicker than conventional methods and also allows the designing of carbon-fiber composites from the nanoscale.

Climate change projected to increase seasonal East African rainfall
According to research led by The University of Texas at Austin, seasonal rainfall is expected to rise significantly in East Africa over the next few decades in response to increased greenhouse gases. The study, published in Climate Dynamics, used high-resolution simulations to find that the amount of precipitation during the rainy season known as the 'short rains' could double by the end of the century, continuing a trend that has been observed in recent years.

Youth's risks from first-time opioid prescriptions may not be as high as once thought
Young adults and adolescents who are prescribed opioids for the first time may be at a slightly greater risk of developing a substance-related problem later in life, according to a new study co-authored by Indiana University researchers. However, the risk may not be as high as previously thought.

Advanced Functional Materials
Electronic components join forces to take up 10 times less space on computer chips
Electronic filters are essential to the inner workings of our phones and other wireless devices. They eliminate or enhance specific input signals to achieve the desired output signals. They are essential, but take up space on the chips that researchers are on a constant quest to make smaller. A new study demonstrates the successful integration of the individual elements that make up electronic filters onto a single component, significantly reducing the amount of space taken up by the device.

Discovery transforms understanding of hydrogen depletion at the seafloor
Results of a new study by Lehigh University's Jill McDermott and colleagues contradict the assumption that hydrogen depletions at the seafloor are caused by microbiological communities. They found that these shifts in chemistry are driven by non-biological processes that remove energy before microbial communities at the shallow seafloor gain access to it. The results were published online today in the Proceedings of the National Academy of Sciences.
