More than 80 percent of schools in America use toxic pesticides as a preventative measure, whether it‘s needed or not.

Mark Lame, an entomologist and professor at Indiana University‘s School of Public and Environmental Affairs, believes this is an entirely unnecessary practice that carries more risks than benefits to students and faculty.

The most widely used pesticides are, in fact, nerve poisons. They cause uncontrolled nerve firing, and disrupt the delicate hormone systems.

The link between pesticide exposure and health problems in children is already well established. Research has connected these endocrine-disrupting pesticides to health problems such as ADHD, autism, and infertility -- all of which are on the rise.

Professor Lame says pest problems are better managed through an integrated approach -- by preventing the conditions that attract pests into school facilities in the first place.

Lame serves as a consultant for schools around the country, helping them reduce the toxic load by implementing his Integrated Pest Management (IPM) process.

People with two pediatric-onset neurodevelopmental disorders are prescribed opioids at a rate up to five times higher than those who do not have those conditions, a new study finds. Researchers say the findings raise concerns over addiction, overdose and mental health issues.

Bioengineers have developed the first biohybrid model of human ventricles with helically aligned beating cardiac cells, and have shown that muscle alignment does, in fact, dramatically increases how much blood the ventricle can pump with each contraction.

Researchers provide some of the first empirical evidence that brain ripples exist. These electrical waves have long been hypothesized as a way for the brain to integrate and encode memories.

Using a state-of-the-art method, researchers have succeeded for the first time at unraveling the effects of autoimmune antibodies, that are directed against the brain, in detail at the atomic level. To this end, they studied two antibodies that dock to so-called GABA-A receptors in one variant of autoimmune encephalitis. Their findings on the structural mechanisms are an important step towards the development of effective therapies -- and they also pave the way for further promising investigations using the new method.

Viewing art while visiting galleries and museums can have powerful effects on an individual's mood, stress and well-being. But does the same hold true for viewing art in digital space? A new study investigated whether engaging with art online also has this effect. Their conclusion: a short three-minute visit to an online art or cultural exhibition also shows significant positive effects on subjective well-being.
