Researchers devise new method to get the lead out

Now they can better measure lead in your tap water

Commercially sold water filters do a good job of making sure any lead from residential water pipes does not make its way into water used for drinking or cooking.

Filters do not do a good job, however, of letting the user know how much lead was captured.

Until now, when a researcher, public works department or an individual wanted to know how much lead was in tap water, there wasn’t a great way to find out. Usually, a scientist would look at a one-liter sample taken from a faucet.

Researchers in the McKelvey School of Engineering at Washington University in St. Louis have devised a new method that allows them to extract the lead from these “point-of-use” filters, providing a clearer picture of what’s coming out of the faucet.

And they can do it

Machine learning helps pinpoint sources of the most common cardiac arrhythmia

Researchers from Skoltech and their US colleagues have designed a new machine learning-based approach for detecting atrial fibrillation drivers, small patches of the heart muscle that are hypothesized to cause this most common type of cardiac arrhythmia. This approach may lead to more efficient targeted medical interventions to treat the condition that is estimated to affect more than 33 million people worldwide, according to the American Heart Association. The recent paper was published in the journal Circulation: Arrhythmia and Electrophysiology.

The mechanism behind atrial fibrillation (AF), a type of abnormal heart rhythm that is associated with increased risk of heart failure and stroke, is yet unclear. Research suggests it may be caused and maintained by what’s called reentrant AF drivers, highly localized sources of repetitive rotational activity that lead to irregular heart rhythm. These drivers can be burnt via a surgical procedure, which

Reduction by reduction: Novel approach to mitigating chromium contamination in wastewater

Scientists report a novel method based on the chemical reaction ‘reduction,’ which can help in efficient control of chromium toxicity in wastewater

The element chromium, despite having various applications, has a bad reputation. This is because exposure to chromium compounds leads to a higher risk of respiratory cancer and other damaging effects on human health. To add to this problem, chromium also happens to be a major contributor to water pollution due to its presence in industrial waste.

There is, however, a silver lining. As chemists have observed, the toxicity of chromium is dependent on its “valence state” (a state that is dictated by the number of electrons in the outer shell of an atom). Of the two stable states that chromium exhibits, “hexavalent chromium” or Cr(VI) and “trivalent chromium” Cr(III), the former is more toxic and soluble. Thus, chromium contamination can be

Can individual differences be detected in same-shaped pottery vessels by unknown craftsmen?

Credit: ©2020 Gandon et al.

An interdisciplinary research team has investigated whether there are quantitative differences that can be used to identify individual potters who make traditional, fixed-shape vessels that have been made in the same way for generations. Consequently, they discovered that there are clear variations between individuals in the formation process and hand movements used.

Members of the research team included Dr. Enora Gandon (Institute of Archaeology, University College London), Professor NONAKA Tetsushi (Graduate School of Human Development and Environment, Kobe University), and Professor Emeritus John A. Endler (Deakin University).

Up until now, the transmission of cultural traditions has been viewed in terms of ‘imitation’ and ‘transmitted information’. However, the results quantitatively show that other factors beyond imitation, such as the individual’s corresponding ability and exploratory learning process, play a role. In addition, it is hoped that these results will serve as a basis for determining whether unattributed

Estimating risk of airborne COVID-19 with mask usage, social distancing

WASHINGTON, October 26, 2020 — The continued increase in COVID-19 infection around the world has led scientists from many different fields, including biomedicine, epidemiology, virology, fluid dynamics, aerosol physics, and public policy, to study the dynamics of airborne transmission.

In Physics of Fluids, by AIP Publishing, researchers from Johns Hopkins University and the University of Mississippi used a model to understand airborne transmission that is designed to be accessible to a wide range of people, including nonscientists.

Employing basic concepts of fluid dynamics and the known factors in airborne transmission of diseases, the researchers propose the Contagion Airborne Transmission (CAT) inequality model. While not all factors in the CAT inequality model may be known, it
