Flame retardant sharks?

Flame retardants are found everywhere from your house to your car. Unfortunately, these chemicals can accumulate in the environment, including the ocean. Once in the ocean, flame retardants can make their way into marine organisms. The researchers in this study wanted to determine if flame retardants are transferred from mothers to offspring in sharks.

Assessing the impact of pollutants on kidney health

Do PFASs affect human health? What even are PFASs? Researchers at Duke University conducted a comprehensive review of the published literature to summarize what we know about how a class of pollutants called PFASs may impact human kidney health.

Near-death experiences: sublethal effects of pesticides on pollinating insects

Negative impacts of pesticides on pollinators can take different forms: direct kills on contact (called lethal effects) or indirect effects, through the pollinators’ abilities to reproduce (called sublethal effects). These sublethal effects are generally not spotted by regulatory bodies through traditional ecotoxicological tests, but have severe impacts on pollinator health.

The science behind the pesticide that was almost banned

Last year, there was considerable news coverage on the Environmental Protection Agency’s (EPA) decision to not ban chlorpyrifos, a pesticide which is believed to cause negative effects on brain development in children. While a lot of the media coverage focused on the nature of the decision, little was reported on the science itself. Thus, I have summarized below EPA’s assessment on the health effects of the pesticide on humans.

Drug resistance in one of the remote regions of the world

Drug resistance is a common problem due to the human activities. Indiscriminate use of antibiotics has resulted in the development of resistance in disease-causing bacteria (microorganisms) found in soil. But, scientists have also found this resistance even in the soil from remote regions far away from human influence.

Spawn of the Dead

Migratory animals such as the Pacific salmon are critical to the transport of nutrients and energy across large distances and between different ecosystems. However, along with important nutrients also come contaminants and pollutants. To understand the impacts of salmon, Brandon Gerig and colleagues investigate contaminant levels of riparian fish populations in streams where salmon runs do and do not occur in the Great Lakes region.

Beefore It’s Too Late: A Study of Diminishing Bee Populations and Why We Must Act Now!

There has been a major decline in bee populations over the past 50 years, although demand for insect pollination has tripled. In their article, Dave Goulson and colleagues touch on problems such as habitat loss, intensification of agriculture, and increasing reliance on pesticides, which can mean pollinators are chronically exposed to harmful chemicals faster due to climate change. About 75% of our crop species benefit from insect pollinators, which provide a global service worth $ 215 billion in food production. If we enter the pollination crisis, crop yields may begin to fall which is concerning for the future generations.
