More than 1,000 leading artificial intelligence (AI) and robotics researchers and others, including Stephen Hawking and Elon Musk, just signed and published an open letter from the Future of Life Institute (FLI) today calling for a ban on offensive autonomous weapons.

FLI defines “autonomous weapons” as those that select and engage targets without human intervention, such as armed quadcopters that can search for and eliminate people meeting certain pre-defined criteria, but do not include cruise missiles or remotely piloted drones for which humans make all targeting decisions.

Let’s formulate the task of life extension slightly differently. Something like this…How can we extend sex appeal?

Gyms and beauty salons are in charge of this question now. There is some success, but it’s mostly superficial. Plastic surgery only masks, but doesn’t delay the processes of aging.

Expanding sex appeal is a complex task. Its aspects include both beauty and the activity of the brain. To be sexually attractive we have to be smart and fun. One cannot solve the problem of dementia with makeup.

We have to be in an excellent physical shape to be sexually attractive, but also things should be running smoothly with our hormonal regulation.

The task of extending the period of sex appeal is extremely science-intensive. It is not only the Viagra, but a complex impact on the whole organism. It is obvious that molecular biology is responsible for sex in the modern world.

UT Dallas scientists have constructed novel fibers by wrapping sheets of tiny carbon nanotubes to form a sheath around a long rubber core. This illustration shows complex two-dimensional buckling, shown in yellow, of the carbon nanotube sheath/rubber-core fiber. The buckling results in a conductive fiber with super elasticity and novel electronic properties. (credit: UT Dallas Alan G. MacDiarmid Nanotech Institute)

An international research team based at The University of Texas at Dallas has made electrically conducting fibers that can be reversibly stretched to more than 14 times their initial length and whose electrical conductivity increases 200-fold when stretched.

One of the most symbolic and substantively important examples of environmental conflict is over Yellowstone National Park. Yellowstone is the first national park in the world, and perhaps the most important natural treasure in the US. More recently it has become a site for bitter and long-lasting environmental conflict. And it has made me wonder how the scientific arguments around the issues sit with the emotional reactions inspired by the landscape and history.

The investigation into the dwarf planet Ceres‘ mysterious bright spots has taken an intriguing new twist. The famous bright spots at the bottom of Ceres’ Occator crater appear to be sublimating material into space, creating a localized atmosphere within the walls of the 57-mile-wide (92 kilometers) hole in the ground, new observations by NASA’s Dawn spacecraft suggest.
