Nanospears deliver genetic material to cells with pinpoint accuracy
Posted by Carse Peel in categories: biotech/medical, genetics, life extension, nanotechnology
UCLA scientists have developed a new method that utilizes microscopic splinter-like structures called “nanospears” for the targeted delivery of biomolecules such as genes straight to patient cells. These magnetically guided nanostructures could enable gene therapies that are safer, faster and more cost-effective.
The research was published in the journal ACS Nano by senior author Paul Weiss, UC Presidential Chair and distinguished professor of chemistry and biochemistry, materials science and engineering, and member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.
Gene therapy, the process of adding or replacing missing or defective genes in patient cells, has shown great promise as a treatment for a host of diseases, including hemophilia, muscular dystrophy, immune deficiencies and certain types of cancer.

Laser weapons: Is this the dawn of the death ray?
Posted by Klaus Baldauf in categories: drones, military
When the first laser was invented the idea of using it as a superweapon seemed like science fiction. Almost 60 years later and it still seems that way, despite a remarkable degree of progress. Prototypes have been used to destroy small watercraft, shoot down missiles and drones, and have even been deployed at least once in a war zone, but the revolutionary destructive ray that would change the face of battle as fundamentally as the longbow or the airplane has yet to appear. So just what is the current state of laser weapons technology, and what does it hold in store for the future of warfare?

Optical computers light up the horizon
Posted by Genevieve Klien in categories: mobile phones, space, supercomputing
Since their invention, computers have become faster and faster, as a result of our ability to increase the number of transistors on a processor chip.
Today, your smartphone is millions of times faster than the computers NASA used to put the first man on the moon in 1969. It even outperforms the most famous supercomputers from the 1990s. However, we are approaching the limits of this electronic technology, and now we see an interesting development: light and lasers are taking over electronics in computers.
Processors can now contain tiny lasers and light detectors, so they can send and receive data through small optical fibres, at speeds far exceeding the copper lines we use now. A few companies are even developing optical processors: chips that use laser light and optical switches, instead of currents and electronic transistors, to do calculations.

New LightSail 2 Spacecraft Will Boost Solar-Sailing Interplanetary Missions
Posted by Genevieve Klien in categories: futurism, space travel
The Planetary Society’s LightSail 2 spacecraft will be a test bed for future missions wanting to use solar sails — including NASA’s proposed Near-Earth Asteroid Scout cubesat.
Meet ESASky, a discovery portal that provides full access to the entire sky. This open-science application allows computer, tablet and mobile users to visualise cosmic objects near and far across the electromagnetic spectrum.
