Newly developed switch activates genes thousands of times better than nature
Posted by Shailesh Prasad in categories: biotech/medical, health
If scientists could precisely regulate gene expression, they could turn off the genes responsible for illness and disease and turn on those that enhance health and the immune system.
âThis is why controlling gene expression is so fundamental,â said Northwestern Universityâs Julius Lucks. âOnce you get a good handle on it, you can do anything.â
For Lucks, having a âgoodâ handle on gene expression might be an understatement. He and his team have developed a powerful and versatile tool that achieves gene activation thousands of times better than nature.

NASAâs New Ion Thruster Engine Is Breaking Some Important Records
Posted by Shailesh Prasad in categories: military, space travel
NASAâs new X3 thruster, which is being developed by researchers at the University of Michigan in collaboration with the agency and the US Air Force, has broken records in recent test. Itâs hoped that the technology could be used to ferry humans to Mars.
The X3 is a type of Hall thruster, a design that uses a stream of ions to propel a spacecraft. Plasma is expelled to generate thrust, producing far greater speeds than are possible with chemical propulsion rockets, according to NASA.

Synthetic Biology and Evolution
Posted by Klaus Baldauf in categories: bioengineering, biological, evolution
Darwinian evolution is old-fashioned. Bioengineering raises new principles for the creation of life but, to what extent can we dispense with the past of our biology.
Love in the time of robots
Hiroshi IshiÂguro builds androids. Beautiful, realistic, uncannily convincing human replicas. Academically, he is using them to understand the mechanics of person-to-person interaction. But his true quest is to untangle the ineffable nature of connection itself.

New NASA research is helping to refine our understanding of candidate planets beyond our solar system that might support life.
âUsing a model that more realistically simulates atmospheric conditions, we discovered a new process that controls the habitability of exoplanets and will guide us in identifying candidates for further study,â said Yuka Fujii of NASAâs Goddard Institute for Space Studies (GISS), New York, New York and the Earth-Life Science Institute at the Tokyo Institute of Technology, Japan, lead author of a paper on the research published in the Astrophysical Journal Oct. 17.

It Still Doesnât Really Matter What A.I. Can Score on IQ Tests
Posted by Dan Kummer in category: robotics/AI
This has a look at where the intelligence of AI is at right now:
âthe researchers came up with a means of testing intelligence that can be translated onto a 100-point scale. They purportedly administered their tests to actual human adults in 2014, and the average score for those 18 years or older was just around 97 points. A 6-year-old human averaged out to a score of 55.5.
In the 2016 A.I. testing rounds, no machine was able to crack the 50-point threshold, but Google Assistant got close. Based on testing in 2016, Google Assistant racked up a 47.28. The Chinese personal assistant Duer, created by Baidu, scored 37.20. Bing came out to 31.98. Appleâs Siri rounded out the top 10 with a score of 23.94.â
