  • Heating an insecticide can give it new life.

      Wait, what? Do say more.....
  • Microwaving the insecticide deltamethrin rearranges its crystal structure but doesn’t change its chemical composition. The rearrangement renews deltamethrin’s ability to kill mosquitoes that have become resistant to the insecticide, researchers report April 21 in Malaria Journal.

      Hmmmm... something similar to this smells like: feasibility.
  • The microwave worked just as well, but Kahr cautions that people shouldn’t use the same microwave for heating food and insecticides.

  • insecticide resistance is a growing problem
  • It is encouraging that heated insecticide killed highly resistant mosquitoes, says Hemingway, who directs the Infection Innovation Consortium, a public-private effort to find new ways to combat infectious diseases. But, she says, “this is not something we can take and use that tomorrow.”

      OK.... this is how you can find an opening (not saying THIS ONE is necessarily, but, when you see language like: "we can't really do it just yet," that is a screaming opportunity to see what we MIGHT be able to add to that.
  • It’s not certain that the heat-treated deltamethrin would retain its more potent crystal structure through the net-making process.
  • Kahr’s team is working on incorporating the heat-treated crystal into nets.
  • “There are all kinds of social and cultural things that you could propose from a scientific perspective that wouldn’t be welcomed by a community of homeowners.”

      Again... this reads: "potential research opportunity."
  • Kahr and colleagues previously discovered that heating deltamethrin changed its crystal structure, which let it work faster

Airplane Noise Exposure May Increase Risk of Chronic Disease | SPH - 0 views

  • “Prior research has shown that aircraft noise can elevate stress responses and disturb sleep, but there has been mixed evidence of any links with body mass index,” says study lead and corresponding author Matthew Bozigar, assistant professor of epidemiology at OSU and a former postdoctoral associate at SPH. “We were surprised to see a fairly robust link between aircraft noise and higher body mass index among women across the US.”

      Again, this reminds me of the UCSD juncos and the increased stressors they must endure to live in an urban environment. However, we must remember that just because their emerging population in and around the UCSD campus is successful, it comes with a cost of shorter lifespans, increased mortality, etc. Very interesting stuff.
  • These new findings underscore the role of the environment on one’s risk of chronic disease.
  • Junenette Peters, associate professor of environmental health, and colleagues examined airplane noise exposure and self-reported BMI and other individual characteristics among nearly 75,000 participants living around 90 of the major US airports
  • ...5 more annotations...
  • The team examined aircraft noise levels every five years from 1995 to 2010, using a day-night estimate (DNL) that captures the average noise level over a 24-hour period and applies a 10 dB adjustment for aircraft noise occurring at night, when background noise is low.
  • Although the team acknowledges that BMI is a suboptimal metric, the independent and strong association between more aircraft noise exposure and higher BMI that they observed is notable.
  • “We can only hypothesize about why we saw these regional variations, but one reason may relate to the era of regional development, building characteristics, and climate which may affect factors such as housing age, design, and level of insulation,” says Peters. “Regional differences in temperature and humidity may influence behaviors such as window opening, so perhaps study participants living in the West were more exposed to aircraft noise due to open windows or housing type, which allowed more noise to penetrate.”
  • Previous data suggest that Black, Hispanic, and low-income populations are disproportionately exposed to aircraft noise. The participants in the NHS study groups were primarily White and of mid-level socioeconomic status. 
  • “We need to study the potential health impacts of environmental injustices in transportation noise exposures alongside other environmental drivers of poor health outcomes” Bozigar says. “There is a lot more to figure out, but this study adds evidence to a growing body of literature that noise negatively impacts health.”

    This makes me think of my Mom and her struggle with migranes. She would benefit from a simple iOS app that helps her track symptoms & potential triggers in a way that could easily be shared with her doctor.
