Exposure to “everywhere chemical” linked to childhood cancer risk

Exposure to phthalates, a common chemical used to manufacture thousands of everyday products, has been linked to an increased risk of childhood cancer. The new findings add to a growing body of research suggesting this pervasive chemical may cause a nu… Continue reading Exposure to “everywhere chemical” linked to childhood cancer risk

Childhood lead exposure cut IQ of over half of US population, study finds

Striking new research published in the journal Proceedings of the National Academy of Sciences estimates lead exposure, primarily from car exhaust, has negatively affected the IQ of about half the population of the United States. The study calculated c… Continue reading Childhood lead exposure cut IQ of over half of US population, study finds

New source of potent greenhouse gas emissions identified in permafrost

It may not be the headline star of the climate change discussion, but nitrous oxide (N2O) is still a potent greenhouse gas – and now it looks like we may have underestimated how much is being released. A new study has identified the thawing Siberian pe… Continue reading New source of potent greenhouse gas emissions identified in permafrost

Plant-based biodegradable glitter sparkles without the microplastics

Glitter spruces up everything from makeup to craft projects, but one thing it doesn’t improve is the environment. Researchers at Cambridge University have now developed a biodegradable glitter that swaps out the plastic and aluminum for plant-based cel… Continue reading Plant-based biodegradable glitter sparkles without the microplastics

Toxic lead found in over half of blood samples from US children

The first large-scale study to look at very low levels of lead in blood samples from children has been conducted

A new study published in JAMA Pediatrics is reporting one half of American children under the age of six have detectable levels of lead in their blood. The research looked at recent blood test results from over one million children and is the first study of this scale to analyze minute traces of lead in blood samples.

Scientists toilet-train cows to reduce their environmental impact

Agriculture is a huge environmental issue in many ways, but one that’s often overlooked is livestock urination. Researchers from Germany and New Zealand have now demonstrated a potential way to reduce that problem – by toilet-training cows.Continue Rea… Continue reading Scientists toilet-train cows to reduce their environmental impact

“Nanojars” capture carbon dioxide dissolved in water

Carbon dioxide in the atmosphere attracts most of the attention in environmental concerns, but much of that ends up in oceans, making them more acidic. Now scientists have created “nanojars” that can easily capture this and other pollutants from water…. Continue reading “Nanojars” capture carbon dioxide dissolved in water

“World Avoided” model charts climate cost if we’d ignored ozone hole

It’s easy to feel hopeless in the face of climate change, but it’s not too late to do something about it – after all, we’ve stepped up to similar challenges before. New modeling shows just how much worse the situation would be if CFCs hadn’t been banne… Continue reading “World Avoided” model charts climate cost if we’d ignored ozone hole

Volcanic brine mines could be green sources of copper, gold and lithium

One hurdle standing in the way of a transition to renewable energy is the increased need for mining that these technologies bring. Now, Oxford scientists are investigating a new way to mine valuable metals trapped in hot brines beneath volcanoes – with… Continue reading Volcanic brine mines could be green sources of copper, gold and lithium
