Experiments in microgravity allow Axelbaum, collaborators to observe flames that can’t be created on Earth Hot flames (left) give way to cool flames (right). (Image: University of Maryland/Peter Sunderland) July 16, 2021 SHARE An entirely new class of fire, spherical cool diffusion flames, appropriately referred to as “cool flames,” has been documented by a collaborative team of researchers from Washington University in St. Louis, the University of Maryland and the University of California, San Diego. Creating this unique fire required an equally unique laboratory: the microgravity environment of space. Axelbaum “The Space Station is a lab like no other,” said Richard Axelbaum, the Stifel & Quinette Jens Professor of Environmental Engineering Science in Washington University’s Department of Energy, Environmental & Chemical Engineering in the McKelvey School of Engineering.

Two Bears make it to the big leagues | The Source | Washington University in St Louis

Please forgive Caleb Durbin and Ryan Loutos if they haven’t gotten back to you. The two standouts from the Washington University in St. Louis baseball team have been inundated with congratulatory calls and texts since July 13 when both signed deals with Major League Baseball teams  Durbin as a 14th-round draft pick to the Atlanta Braves and Loutos as an undrafted free agent to the St. Louis Cardinals.  “Within 10 minutes, I got 100 messages on my phone,” said Durbin, who hit .386 as the Bears shortstop. “It’s just been an amazing and surreal experience.”  “It’s so cool and so humbling,” said pitcher Loutos, whose 11-1 record led the Bears to their first NCAA Division III World Series this June. “You realize how much you value those people who have supported you all of the way.” 

Static magnetic field from MRI scanner decreases blood-brain barrier opening volume

Static magnetic field from MRI scanner decreases blood-brain barrier opening volume MRI-guided focused ultrasound combined with microbubbles can open the blood-brain barrier (BBB) and allow therapeutic drugs to reach the diseased brain location under the guidance of MRI. It is a promising technique that has been shown safe in patients with various brain diseases, such as Alzheimer s diseases, Parkinson s disease, ALS, and glioblastoma. While MRI has been commonly used for treatment guidance and assessment in preclinical research and clinical studies, until now, researchers did not know the impact of the static magnetic field generated by the MRI scanner on the BBB opening size and drug delivery efficiency.
