Roughly one in four U.S. households have soil exceeding the new U.S. Environmental Protection Agency's lead screening levels of 200 parts per million (ppm), halved from the previous level of 400 ppm, a new study found. For households with exposure from multiple sources, the EPA lowered the guidance to 100 ppm; nearly 40% of households exceed that level, the study also found.

Measuring the heart rate of great apes in captivity is essential for both health management and animal studies. However, existing most methods are either invasive or inaccurate. Now, researchers have investigated the potential of using millimeter-wave radar technology to estimate heart rate from subtle body movements in chimpanzees. Their efforts will hopefully pave the way to better practices and techniques for monitoring heart rates in wild and captive primates.

An innovative synthesis strategy opened up the way to 2D/3D fused frameworks using inexpensive quinolines as feedstock, report scientists. By leveraging a light-sensitive borate intermediate, the scientists could transform quinoline derivatives into a great variety of 2D/3D fused frameworks in a straightforward and cost-effective manner. Their findings are expected to enable the synthesis of highly customizable drug candidates.
