X-rays and nanoparticles combine to kill cancer deep in the body

Cancer may be terrifying, but cancerous cells aren't actually that difficult to kill. The tricky bit is doing so without killing the host or making them dreadfully ill in the process. The key is treatments that only target the cancer cells while leaving the surrounding healthy tissue alone. By combining X-rays with nanoparticles, a team of researchers from the Centre for Nanoscale BioPhotonics (CNBP) in Australia has found a way of combating cancer deep inside the body in this way using a simple chemical.

Apollo 14 astronaut Captain Edgar Dean "Ed" Mitchell dies at age 85

Some of us of a certain age felt a little bit older today after news that Captain Edgar Dean "Ed" Mitchell has died age 85. The US Navy veteran and NASA astronaut was the Lunar Module Pilot on the Apollo 14 mission in 1971 and was the sixth man to walk on the Moon. He passed away on Thursday at 10:00 pm EST in hospice care at Lake Worth, Florida.

Shape memory alloys the basis for more efficient refrigerant-free cooling

By preserving our food and keeping our buildings comfortable in hot weather, mechanical cooling systems have been a boon, but with their refrigerant gases and high power consumption they're not exactly environmentally friendly. In an effort to make a greener, more energy efficient cooling system, a team of engineers from Germany's Saarland University is turning to shape memory materials to replace the refrigerant gases used in conventional cooling technologies.

Orion arrives at Kennedy Space Center

The second Orion Crew module has arrived at the Kennedy Space Center's Operations & Checkout Facility after a flight by Superguppy from the Michoud Assembly Facility in New Orleans. According to primary contractor Lockheed Martin, the 2,700 lb (1,225 kg) spacecraft has been secured in its structural assembly tool called the "birdcage," where it will undergo testing and assembly for its first flight atop the Space Launch System on the unmanned Exploration Mission-1 (EM-1) scheduled for November 2018.

Swarming robot boats demonstrate self-learning

Robots may be the wave of the future, but it will be a pretty chaotic future if they don't learn to work together. This cooperative approach is known as swarm robotics and in a first in the field, a team of engineers has demonstrated a swarm of intelligent aquatic surface robots that can operate together in a real-world environment. Using "Darwinian" learning, the robots are designed to teach themselves how to cooperate in carrying out a task.

Sorry Spider-Man, but geckos are the largest wall crawlers

Having faced off the Green Goblin and Mysterio, Spider-Man has been defeated by his greatest enemy; maths. According to a team of scientists from Cambridge University, for the webslinger to stick to a wall, he'd need hands and feet equal to 40 percent of his entire body surface area. Though this may dismay web head's fans, it may shed insights into how to improve gecko-like adhesives.

Graphene optical lens a billionth of a meter thick breaks the diffraction limit

With the development of photonic chips and nano-optics, the old ground glass lenses can't keep up in the race toward miniaturization. In the search for a suitable replacement, a team from the Swinburne University of Technology has developed a graphene microlens one billionth of a meter thick that can take sharper images of objects the size of a single bacterium and opens the door to improved mobile phones, nanosatellites, and computers.

Hybrid polymer shows promise in self-repairing materials, smart drug delivery, and artificial muscles

We live in an age of plastics, but even after a century of progress, most polymers still come in a single, homogenous form with basic properties. Now a team of researchers at Northwestern University under the leadership of materials scientist Samuel Stupp have developed a hybrid polymer that combines soft and hard areas like bones and muscles in animals. According to the team, this breakthrough in nanoengineering opens the door to applications ranging from self-repairing materials to artificial muscles.
