A digital model has revealed a complex planetarium on the ancient device’s face. “Unless it’s from outer space, we have to find a way in which the Greeks could have made it,” researchers say.
3D printed rockets save on up front tooling, enable rapid iteration, decrease part count, and facilitate radically new designs. For your chance to win 2 seats on one of the first Virgin Galactic flights to Space and support a great cause, go to https://www.omaze.com/veritasium.
The rover will dig deeper into Mars than any previous mission in search of ancient life.
The rover, set for launch in 2,022 will bring to a head a decades-in-development program that has suffered a series of setbacks. If all goes well, the Rosalin Franklin rover may be scientists’ best shot at getting a definitive answer about whether there was ever life on Mars and what its fate can tell us about our own planet.
To figure out how the body changes over time, researchers are increasingly looking to understand epigenetics, the study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself. This scientific endeavor extends to teeth as well.
Yang Chai, associate dean of research at the Herman Ostrow School of Dentistry of USC, reported in a recent article how he and colleagues discovered that epigenetic regulation can control tooth root patterning and development.
We’ve seen a lot of electric vehicle growth and success stories in the past several years, but one area that’s been a bit of a letdown has been the semi truck market. Unfortunately, we still don’t have the Tesla Semi, and it was recently delayed until 2,022 and a big side area of that market that “futurists” have long been excited about is potential self-driving trucks. Platoons of self-driving semi trucks are especially exciting since tight, train-like caravans of semi trucks would use far less energy than the current system, and those trucks could much more easily be cost-competitive electric trucks with zero tailpipe emissions. Anyway, though, we’re getting ahead of ourselves again.
In a new study, researchers have shown that antibiotic cycling — which involves doctors switching between antibiotics to overcome antibiotic resistance — may be an ineffective and unsustainable strategy.
New research sheds light on the potential limitations of ‘antibiotic cycling’ as a way of combatting antibiotic resistance.
