DEF CON 24 Homework Begins!

Posted by in categories: entertainment, neuroscience

As you know, DEF CON 24’s theme is “Rise of the Machines”. To help you get up to speed on some of the ideas that inspired the theme, and get you thinking about the looming conflict between human and machine intelligences, we’re going to post some books, movies, and other media you might want to check out in advance of the con.

This is the first book post — there will …be more. If you have others you think would be worth looking over before the con, share in the comments!

Researchers ride new sound wave to health discovery

Posted by in categories: biotech/medical, health

Yelling at stem cells.


Acoustics experts have created a new class of sound wave — the first in more than half a century — in a breakthrough they hope could lead to a revolution in stem cell therapy.

The team at RMIT University in Melbourne, Australia, combined two different types of acoustic sound waves called bulk waves and surface waves to create a new hybrid: “surface reflected bulk waves”.

Planetary Resources reveals first object 3D printed from alien metal

Posted by in categories: 3D printing, materials

Up until now, everything we’ve ever used in space has been brought there from Earth. Planetary Resources Inc. has long-term ambitions to mine the infinite resources space provides. In the mean-time, they’ve proven its possible by 3D printing material derived from an asteroid.

Material could harvest sunlight

Posted by in categories: materials, solar power, sustainability, transportation

Imagine if your clothing could, on demand, release just enough heat to keep you warm and cozy, allowing you to dial back on your thermostat settings and stay comfortable in a cooler room. Or, picture a car windshield that stores the sun’s energy and then releases it as a burst of heat to melt away a layer of ice.

According to a team of researchers at MIT, both scenarios may be possible before long, thanks to a new material that can store solar during the day and release it later as , whenever it’s needed. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.

Although the sun is a virtually inexhaustible source of energy, it’s only available about half the time we need it—during daylight. For the sun to become a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering in the form of electricity, but the new finding could provide a highly efficient method for storing the sun’s energy through a chemical reaction and releasing it later as heat.

We Finally Know What’s Causing Galaxy Quakes

Posted by in category: cosmology

Did you need another existential risk to keep you up at night? Probably not, but here it is anyway: galaxy quakes. We’ve known about ‘em for years, and we hadn’t a clue what causes them—until now.

The culprit, unveiled today at the 227th meeting of the American Astronomical Society, is about as weird as you’d expect. Astronomers now believe that ripples in gas around the edge of the Milky Way are the result of a dwarf galaxy filled with dark matter ramming up against us several hundred million years ago.

Sukanya Chakrabarti of the Rochester Institute of Technology reached that bizarre conclusion by measuring the speed of three bright stars, called Cepheid variables, at the Gemini Observatory in Chile. These stars, which are suspected to hail from a larger population that entered our Milky Way during the Great Galactic Quaking of 300 million B.C., are all speeding away from us at about 450,000 mph.

New Evidence Suggests Human Beings Are a Geological Force of Nature

Posted by in category: materials

For years, the term “Anthropocene” has been used to informally describe the human era on Earth. But new evidence suggests there’s nothing informal about it. We’re a true force of nature — and there’s good reason to believe we’ve sparked a new and unprecedented geological epoch.

A team of international geoscientists say the time has come for us to formally recognize the Anthropocene as a new epoch, one as significant as previous geological eras like the Holocene and Pleistocene. According to the new study, which appears in the latest issue of Science, it began sometime around the midpoint of the 20th century, and is fueled by a number of unquestionably human influences — including elevated greenhouse gas levels and the global proliferation of invasive species, along with the spread of materials such as aluminium, concrete, fly ash, and even fallout from nuclear testing.
