Fatigue



Chronic fatigue syndrome is a silent disease. Those who have it suffer, but no cause is known and there are no visible symptoms. It is hard for a lot of people who don't have it to understand what it's like to have CFS.

Recently it was proposed that a mouse virus was the cause. This attracted attention, because it having a target gave hope for a treatment and there would be something tangible to understand about the illness. Research now shows that XMRV (the mouse virus) is not likely the cause of CFS. The search for what this illness is continues.

Elephant Walk



Elephants don't do jumping jacks or skip, but they can run fast and walk across a continent. Elephant legs are designed to help them migrate long distances and carry up to 5 tons. Watching an elephant walk one can imagine they are gliding. They distribute weight differently from us with each step. Research recently confirmed that they step more lightly than us (relatively speaking in terms of percent of body weight). To do the research the elephants had to be video taped using motion capture, and each step had to be measured using a very large scale. The attached article should have a photograph of the set-up.

Brain Research



A lot of people are afraid of going to the doctor. Fear of doctors and medical research is impairing scientists' ability to conduct brain studies in China. Some have sought to relax the rigor demanded of scientific articles before they can be published. Others are trying to piggy-back brain research on patients seeking treatment for other conditions.

What information should doctors be allowed to share about their patients for medical research?

Antibiotics



Finish your antibiotics!

Not taking the complete course gives bacteria the chance to become resistant to treatment. Scientists finally know how this happens.

When bacteria are exposed to non-lethal doses of antibiotics they release reactive oxygen into their cells. This causes mutations in the DNA. Some of these mutations provide the bacteria protection against the drugs.

Doctors prescibe doses of antibiotics that will kill the infecting bacteria. When we don't take all the medicine as prescribed our bodies contain just enough of the drugs to cause the mutations but not enough to clear ourselves of the infection.

Do yourself and the rest of humanity a favor and take your doctor's advice. These resistant bacteria can spread to other people and endanger their lives.

Whales and Diatoms



Whales are the worlds largest animals and diatoms are single celled organisms. Despite their small size, diatoms have had a big impact on whales. Filter feeding whales siphon diatoms out of sea water and eat them. In their feeding quest, whales follow diatom blooms. Population habits of diatoms make whales adjust to get the best meals. Overtime whales have evolved to best exploit diatom patterns.

Wireless Regulation



What does asking who owns the wireless networks have to do with science? The way the government regulates who can own them determines the return on investment those owners get. This affects quality of service, because a more competitive market should make the most successful be those providing the best service. Economic researchers looked at market data before and after regulation changes in the secondary market (resale of network rights.) The findings are consistent with theory.

Human Routes



Privacy is defined anew by each generation. We become comfortable with revealing personal information depending on the demands of social norms. Whether it is idyll gossip or shopping habits being tracked at the grocery store, other people try to predict what we will do by studying what we appear to have done.

If we look closely at what it is people can learn about us, we see that we actually share lots of details about our activity. This study shows that knowing simple facts about the members of a population's current location can be used to predict future actions. This work can be applied to understanding daily movements and spread of infectious diseases.
