A New Computer Model Suggests You Could Probably Outrun a T-Rex
New research suggests that Tyrannosaurus Rex could only walk, not run, a big change in its ferocious image.
There are few more alarming cinematic images than the one in which you see a Tyrannosaurus Rex in your car's rear-view mirror barreling up the road behind you in terrifying pursuit.
Now a scientist from the University of Manchester has discovered — and even he says he's disappointed about this — that it's likely T-Rexes couldn't full-out run, limited to a rather unterrifying brisk walk.
Manchester’s William Sellers modeled T-Rex based on everything we know about its height, weight, and bone size and density, and movement. His team utilized multibody dynamic analysis supplemented by machine learning to produce what they say is the most accurate T-Rex model ever.
What Sellers’ model revealed is that if if a T-Rex tried to outrun your car in Jurassic Park, all the bones in its undersized legs would break. (We won't even mention its sad little front legs.) Previous models suggested T-Rex could run as fast as 45 mph, twice as fast as the fastest human, Usain Bolt.
It turns out that the fastest speed a Tyrannosaur could manage would've been about 12 mph, which is about three mph slower than the average adult human can run when chased by something huge and hungry.
Sellers says it's probable that our entire image of the Tyrannosaurus as a fearsome apex predator is wrong. Its pokiness may mean that in spite of scaring the bejesus out of generations of children and adults, "It certainly would not have been able to chase down faster-moving prey animals," Sellers tells Reuters. "That leaves other hunting options such as ambush, and of course it means that (discredited) ideas such as 'T-rex the scavenger' have to be reconsidered."

“I was a little bit disappointed, I have to say,” Sellers tells CBS News, explaining further to Reuters, “The muscles need to be able to generate sufficient power to allow high-speed locomotion, but at the same time the skeleton has to be able to cope with the loads generated by the high speed. This is where it fails. T-rex's skeleton is simply not strong enough for running locomotion.”
Both schizophrenics and people with a common personality type share similar brain patterns.
- A new study shows that people with a common personality type share brain activity with patients diagnosed with schizophrenia.
- The study gives insight into how the brain activity associated with mental illnesses relates to brain activity in healthy individuals.
- This finding not only improves our understanding of how the brain works but may one day be applied to treatments.
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
