The Beating Heart: This Mazda prototype incorporates a Skyactiv-X engine within the body of a Mazda3, but the only way you’d know it is by the high fuel economy and the low tailpipe emissions.

There are lots of reasons why we’re not all driving electric vehicles now. You’ve probably thought of two or three already, but let me add one that I’m sure you haven’t. It’s a big obstacle to EVs, and it’s rarely remarked upon.

It’s the internal combustion engine, which is no sitting duck. It’s a moving target, and a fast-moving one at that.

Damaged Hearts Next in Line for Powerful mRNA Therapies

COVID-19 vaccine technology now points toward repairing ravages of heart attacks

The messenger RNA COVID-19 vaccines, including ones made by Moderna and Pfizer, notched some famous successes and pioneered the use of mRNA technology along the way. Now, scientists are applying testing similar technologies as treatments for a variety of conditions, including heart injury. New research presented in April at the Frontiers in CardioVascular Biomedicine 2022 conference shows that mRNA can help heart cells regenerate after being damaged from a heart attack—and has the potential to be an effective therapy. Other recent research treating cardiac injury using similar approaches has also shown promise. Should these treatments be effective in people, they would be among the first to heal damage after a heart attack, which current treatments for heart attack don't really do.

“A real solution is not provided to the patient,” said Dr. Maria Clara Labonia, a medical doctor and Ph.D student at the University of Utrecht in the Netherlands who is the lead author of the study. “So many aims are towards new therapeutic strategies.”

Achieving the next level in vehicle autonomy demands robust algorithms trained to interpret radar reflections from automotive radar sensors. Overcome the gaps between software simulation and roadway testing to train the ADAS / AV algorithms with real-world conditions. Sharpen your ADAS' radar vision with full-scene emulation that allows you to lab test complex real-world scenario, while emulating up to 512 objects at distances as close as 1.5 meters.
