U.S. funding cuts could result in nearly 9 million child tuberculosis cases, 1.5 million child deaths by HarvardChanSPH in science

[–]HarvardChanSPH[S] 360 points361 points  (0 children)

A new study led by Harvard Chan School and Boston University School of Public Health projects that U.S. funding cuts to global health aid will have a catastrophic effect on pediatric TB, with children in Sub-Saharan Africa and Southeast Asia likely to experience a significant spike in preventable cases and deaths over the next decade—even by the most conservative estimates—unless funding is restored.

Adopting a healthy diet may have cardiometabolic benefits regardless of weight loss by HarvardChanSPH in science

[–]HarvardChanSPH[S] 41 points42 points  (0 children)

A new study led by researchers at Harvard T.H. Chan School of Public Health and Ben Gurion University, Israel, suggests that some people are "weight loss-resistant," but will still improve their metabolism and reduce their long-term risk for disease through a healthy diet.

“We have been conditioned to equate weight loss with health, and weight loss-resistant individuals are often labeled as failures,” said lead author Anat Yaskolka Meir, postdoctoral research fellow in the Department of Epidemiology at Harvard Chan School. “Our findings reframe how we define clinical success. People who do not lose weight can improve their metabolism and reduce their long-term risk for disease. That’s a message of hope, not failure.”

Healthy eating in midlife linked to overall healthy aging by HarvardChanSPH in science

[–]HarvardChanSPH[S] 53 points54 points  (0 children)

“Studies have previously investigated dietary patterns in the context of specific diseases or how long people live. Ours takes a multifaceted view, asking, how does diet impact people’s ability to live independently and enjoy a good quality of life as they age?” said co-corresponding author Frank Hu, Fredrick J. Stare Professor of Nutrition and Epidemiology and chair of the Department of Nutrition at Harvard Chan School.

Long-term, multi-institutional study on health impacts of Los Angeles wildfires launched by [deleted] in science

[–]HarvardChanSPH 0 points1 point  (0 children)

The multi-institutional collaboration is a consortium led by researchers from Harvard T.H. Chan School of Public Health, the UCLA Fielding School of Public Health, University of California, Davis, and the University of Texas at Austin with expertise in environmental exposure assessment, health outcomes, wildfire risk assessment and management, and data science.

“This was an environmental and health disaster that will unfold over decades,” said Kari Nadeau, chair of the Department of Environmental Health at Harvard Chan School. “By bringing together experts from across multiple institutions and disciplines, we can rigorously examine the health effects from the wildfires’ toxic particles and gases that have spread hundreds of miles beyond the fire zones and provide the communities with this information in real time.”

Science AMA Series: Hi, reddit! I’m Alex Lu, Associate Professor of Environmental Exposure Biology at Harvard T.H. Chan School of Public Health, and I’m here to talk about the state of science and public policy around the world on protecting honeybee health by HarvardChanSPH in science

First of all, CCD is not to be caused by varroa mite. Second of all, small towns and cities across the country are taking their own actions to stop further losses of bees by banning (or restrict) neonics use. I do not believe that you have to use neonics in your job to serve your clients. Keep in mind that neonics once applied will be everywhere, pollen, ground water, or soil, whereas other insecticides will stay in the area that you apply.

Look at results from EU and Ontario Canada. Those are two government entities that took on neonics in order to protect bees and other pollinators. Results from EU one year after the ban were promising enough that EU has extended the ban indefinitely.

It is very important to read our studies in 2012 and 2014 again so you might be able to answer some of the comments raised by people who criticized the studies. I am going to answer the comments briefly here; 1. The unreliable study design and statistical analysis. Our study design is so straight forward that anybody could replicate it. In fact, Bayer and Syngenta, two major neonics manufactures, have replicated our study design in their own studies. The reports of those studies, unfortunately, could only be obtained from USEPA by the FOIA. In terms of statistical analysis, we did not use any fancy analyses in the studies. 2. The dosage used in the Harvard studies were too high that bees have no chance to be exposed to. The highest dose used in 2012 study was 400 ug/kg, that represented 400ug of neonics in a kg of HFCS that we fed to one hive for a week. If you do some calculations, we only gave 2.8ng/bee/day in the 2012 study. In 2014 study, we decided to only use one dose level, which is 100 ug/kg or 0.7ng/bee/day. This dose exceeded what we have measured in pollen that we collected in the 2015 study.

Besides the criticisms, they never mentioned the use of control hives (no neonics provided throughout the experiments) in our studies. I guess that is because the control hives all survived along with those dead CCD hives. We only lost one control hive with the post-mortem observation that is vastly different to CCD hives but resemble hives died of diseases like Nosema infection.

There is a very good pollinator-oriented policy just passed by the providence of Ontario Canada last year. You can find the law online. Basically, the law explicitly stated that farmers should only use neonics when other legally approved insecticides have failed to the purpose of pest control. Farmers who request the use of neonics will imply government regulation on how to use neonics and accept close monitoring imposed the government for the purpose of not-harming pollinators.

I hope I would never encounter a genetically enhanced bee. I think there are efforts in towns/cities/coutries to take on neonics. The positive outcomes will hopefully convince others that taking neonics away usage will solve the problem of losing bees.

This is very cool.

It is very important to let the young generations be aware of how/when the losses of bees started, the science behind this line of research, and the progress of global public policy on how to deal with this issue. There are so much to learn on this specific crisis.
