Emergency department visits for motor vehicle-related trauma and convictions for driving under the influence in Houston declined significantly after the ridesharing service Uber debuted there, researchers found.
Compared with the 2007 calendar year, trauma center activations for vehicle accidents in the 12 months ending in November 2019 were 20.1% lower (1,527 vs 1,911), according to Christopher R. Conner, MD, PhD, of the University of Texas Health Science Center in Houston, and colleagues.
For the entire two periods before and after Uber s December 2013 rollout, the rates of motor vehicle trauma visits during peak hours fell 23.8% (0.21 vs 0.26 per hour), the researchers reported in
JAMA Surgery. Injuries became less severe as well, though mortality rates did not change.
Meerut: How does the novel coronavirus thrive in a host’s body? A new study led by an Indian-origin scientist, published in ‘Nature Communications’, has solved one more piece of the puzzle. They have discovered that magnesium, calcium and manganese ions in the body form “a bridge” that helps the virus enter a cell undetected. The findings could pave the way for antiviral drugs that counter the virus.
“Last year, my team and I discovered the mechanism by which the SARS-CoV-2 modifies its messenger RNA (or mRNA) and evades immune system resistance,” said Dr Yogesh Gupta, 42, from the University of Texas Health Science Center, originally from Jasrana in Firozabad. “Now, we have discovered that different metal ions help a process called RNA capping to ensure undetected growth in a host’s body. This is an important breakthrough in our understanding of the mutating virus.”
