I don't think so. The JAMA article http://archinte.jamanetwork.co... does look at longitudinal effects but the 25% figure comes from comparing states with and without. From the abstract:
States with medical cannabis laws had a 24.8% lower mean annual opioid overdose mortality rate (95% CI, 37.5% to 9.5%; P=.003) compared with states without medical cannabis laws.
The common way to statistically analyse the effect of one variable is to model as many variables as the data allows and run a regression to isolate the effect of the target variable.
It may be that there are other problems with the study (e.g. correlations between the variables assumed to be independent) but this isn't one of them.

Electrical Grid Hum Used To Time Locate Any Digital Recording 168
illtud writes "It appears that the Metropolitan Police in London have been recording the frequency of the mains supply for the past 7 years. With this, they claim to be able to pick up the hum from any digital recording and tell when the recording was made. From the article: 'Comparing the unique pattern of the frequencies on an audio recording with a database that has been logging these changes for 24 hours a day, 365 days a year provides a digital watermark: a date and time stamp on the recording.'"

Added to this: low-income people are generally low-income because they don't save their money, but live hand-to-mouth.
May I suggest that causation could be the other way around: Low income people generally live hand-to-mouth and don't save their money because they're low-income people.

Even more impressive is that UV radiation is the spectrum from 10 nm to 400 nm, with extreme UV down the 10nm end. So this at most 2 wavelengths.* It barely gets waving.
