Findings suggest human health risks from inhaling pollen laced with neonicotinoids
FRISCO — Scientists with Harvard University’s T.H. Chan School of Public Health say their new study examining pollen and honey shows there’s a need to develop public policies that aims to reduce neonicotinoid exposure.
After working 62 Massachusetts beekeepers who volunteered to collect monthly samples of pollen and honey from foraging bees, the researchers found more that 70 percent of the samples contained at least one neonicotinoid, a class of pesticide that has been implicated the steep decline of honeybee populations, specifically colony collapse disorder, when adult bees abandon their hives during winter.
The study will be published online July 23, 2015 in the Journal of Environmental Chemistry. Not only do these pesticides pose a significant risk for the survival of honey bees, but they also may pose health risks for people inhaling neonicotinoid-contaminated pollen, Lu said. Continue reading

Above average temperatures are expected to persist across the Far West for the next three months.
Global warming is here …
FRISCO — With El Niño still strengthening in the Pacific Ocean, many parts of the northern hemisphere are breaking all-time heat record this week, including England, where tennis players in the early Wimbledon rounds have to contend with the hottest temperatures ever recorded in the UK.
The ongoing heatwaves parts of Asia, North America and Europe may be a clear sign that 2015 will, as expected, end up as the hottest year on record for the globe, and a sign of trouble ahead, as deadly heatwaves are expected to increase and put millions of people at risk, with the threat growing every year, according to a recent climate study.

New maps can guide prevention efforts
FRISCO — Warmer global temperatures are enabling the spread of disease-carrying mosquitoes, putting millions of people at risk, Oxford University researchers say.
The scientists recently created the first global distribution maps of two species of dengue and chikungunya-carrying mosquitoes, showing a rapid expansion in parts of the US, Southern Europe and China during the past 10-15 years. Continue reading
