Seismic noise unearths lost hurricanes:
[Via Eureka! Science News - Popular science news]
Seismologists have found a new way to piece together the history of hurricanes in the North Atlantic—by looking back through records of the planet’s seismic noise. It’s an entirely new way to tap into the rich trove of seismic records, and the strategy might help establish a link between global warming and the frequency or intensity of hurricanes.

This could be really useful. Essentially, the researchers, using digital files, were able to identify the seismic markers of hurricane activity. The could detect these markers even from seismographs 1000 miles away from the hurricane.
This means that we can now examine seismic data, which extends many years earlier than we have been able to so far, in order to get a better understanding if hurricane activity. Just one big problem:
At least one major hurdle remains before scientists will be able to pull together a complete hurricane history out of the seismic records. For most of the 20th century, seismograms recorded data on rolls of paper. Those records, which contain hundreds of thousands of hours of data, will need to be digitized. Ebeling is looking for an efficient way to do that.

Copper bracelets and arthritis
[Via Health News from NHS Choices]
“Copper bracelets and magnetic wrist straps are useless for relieving pain in people with arthritis,” BBC News has reported. It said that the first tightly controlled study of the interventions found no benefit in treating pain or stiffness from the condition.
This report is based on a robust study design and shows good evidence that magnetic wrist straps and copper bracelets have little or no effect on pain, physical function, stiffness or medication use in people with osteoarthritis.
According to this study, any benefit these devices may have, which the BBC reports can costs between £25 and £65, may be explained by the placebo effect.

I’m really getting to like this site. It does a great job explaining the science and data behind things hat make it into the media. It tells you where the news came from and gives links to the original research article.
It has a nice standard format and provide valuable insight into the research. I often come here right after reading some tidbit in the news tos ee if there is a nice post that easily explain the work. Much easier than doing it myself.
Then I can concentrate on all those stories that do not get followed by the NHS.
