Predicting the Weather on Mars

Over the years, I have learned not to place too much trust in weather forecasters. On a number of occasions, the forecasters have either underestimated or overestimated the severity or timing of predicted storms, or failed to predict weather events altogether. So I read with interest a story discussing NASA...

Software Obsolescence

I have never rushed out to purchase the latest version of a software release. As long as my current software is running my programs smoothly and not experiencing constant freeze-ups, I’d rather not bother with the arduous process of backing up my data and hoping the new software does not stall midway through installation...

Compared to soybeans that produce 50 gallons of oil an acre a year, some algae can average 6,000 gallons - but it's not cheap to produce. Two Kansas State University engineers are assessing...

Robots as Personal Assistants

The increasing presence of robots in industrial applications has been well documented. But robotic technology advances are also trickling down into the consumer market, creating a similar boom in the demand for personal robots. That is the conclusion of a new study by ABI Research titled “Personal Robotics 2009:...

Michigan State University researchers are developing robots that use advanced materials to swim like fish and gather precise data on aquatic conditions. The robotic fish will carry...

Question of the Week
Will Microsoft’s Windows 7 succeed?

This week’s question concerns Microsoft’s Windows 7 operating system. Microsoft released the new operating system last week to generally more favorable reviews than its bug-laden, slow-selling Vista predecessor. While Microsoft claims Windows 7 resolves many of Vista’s flaws, skeptics contend the...

Small-Bolt Torque-Tension Tester

Current torque-tension measurement techniques involve using load washers as the force measuring transducer. The disadvantage of load washers is that they are too large to be used with fasteners smaller than about size #8. The device described here measures the torque-tension relationship for fasteners as small as...
