Robert Zubrin is best known for his advocacy of the manned exploration of Mars.

Zubrin also had a design for interplanetary propulsion called the Nuclear Salt Water Rocket.

A nuclear salt-water rocket (NSWR) is a theoretical type of nuclear thermal rocket. A conservative design for the rocket would be fueled by salts of 20 percent enriched uranium or plutonium. The solution would be contained in a bundle of pipes coated in boron carbide (for its properties of neutron absorption). Through a combination of the coating and space between the pipes, the contents would not reach critical mass until the solution is pumped into a reaction chamber, thus reaching a critical mass, and being expelled through a nozzle to generate thrust.

Reaction Engines of the UK has scaled back its design for the Sabre engine to bring about a demonstrator that is more affordable and better suited to early applications, including a potential X-plane.

The Oxfordshire-based firm has been developing a turbine that combines both jet and rocket technologies to achieve rates five times the speed of sound, to fly anywhere in the world in just four hours.

Rather than aiming for a demonstrator that can achieve more than 150,000 lb thrust, the firm will instead now target an engine size capable of roughly 44,000 lb thrust, according to Aviation Week Network.

In Brief.

• Programmers have developed an artificial intelligence that can play the video game Doom, and do so very well.
• Although it’s just a game, this raises questions about AI governance. How can it become more informed, integrated, effective, and anticipatory?

Crohn’s Disease is a legendarily difficult disease to not only identify but to treat or cure. The disease affects the intestines and digestive tract, stemming from bacteria in those areas building up and leading to serious side effects. It affects more than half a million people in the United States and is brutal – with the possibility of diarrhea, weight loss, fatigue, ulcers, malnutrition, and eventually colon cancer, liver disease or osteoporosis.

Treatment is limited, with the current best options being medicine to limit inflammation and prevent symptoms. There is no complete cure, only efforts to make life as comfortable and normal as possible for those afflicted. Without a specific target at which to aim some sort of treatment, the options for permanently reducing or removing symptoms and health risks are few and far between. Before now, the only thing scientists thought they knew about the disease’s cause was that E Coli was involved.

However, recent studies have led researches to believe that they have narrowed down other bacteria that contributes to the onset and ongoing symptoms of Crohn’s. Experts at the Center for Medical Mycology at Case Western Reserve and University Hospitals Cleveland Medical Center (wow, is that a mouthful!) think they have pinpointed two additional bacterial strains that contribute to the disease. They studied a cross section of people – those with the disease, those with the disease whose family members did not have it, and those without it – to attempt to identify common details in their biological tests. Such a diverse group of subjects is required not only due to the importance of adhering to the scientific method but because Crohn’s can be caused by genetics and environmental factors.

A 3D-printing company is aiding NASA by using its additive manufacturing technology to create an accurate replica of a meteorite located 34 million miles from Earth.

Measuring approximately 2 feet in length, the meteorite known as Block Island was first discovered on Mars by the Exploration Rover Opportunity in 2009. Studying it is an important part of furthering our knowledge about Mars and other planets, but at present the prospect of bringing it to Earth to examine u close is out of the question.

Fortunately, the Mars rover was able to take images and measurements to transmit back home, and this data has now been used by Mcor Technologies, an Ireland-based 3D-printing company, to create a life-size Block Island model.

Hmmmm.

Russia continues to bolster its strength along Northern Europe keeping countries on the edge. According to some, Vladimir Putin may be ready to start invasion as the United States has also started losing to Moscow. Is Russia really going to dominate the world?
