With nearly breakneck speed, the demands of work productivity in today's society seem to have increased tenfold. Enter multitasking as a way to cope with the insistence that tasks be completed almost immediately. Previous studies on workload and productivity include physical aspects, such as how much a person walks or carries, but they do not take into account a person's state of mind. Now, researchers have discovered a person's eyes may offer a solution.

Hypoxic dead zones found in urban streams, not just at the coast

A new study finds that hypoxic dead zones occur in nutrient-laden urban streams, not just in coastal waters. The research shows that intense storm flows can erode some stream channels to become a series of pools that trap nutrient-laden runoff. The elevated nutrient levels in the water spur greater consumption of dissolved oxygen by bacteria, causing the pools to become hypoxic until the next storm flushes them out.

Historic earthquakes test Indonesia’s seismic hazard assessment

Using data gleaned from historical reports, researchers have now identified the sources of some of the most destructive Indonesian earthquakes in Java, Bali and Nusa Tenggara, using these data to independently test how well Indonesia's 2010 and 2017 seismic hazard assessments perform in predicting damaging ground motion.

Stronger pesticide regulations likely needed to protect all bee species, say studies

Regulators worldwide currently use honeybees as the sole model species failing to account for potential threats posed by agrochemicals to the full diversity of bee species from bumblebees to solitary bees, which are probably more important for pollination of food crops than managed honeybees. They are potentially more vulnerable to pesticides given they nest in the ground and bumblebee queens have different life cycles that could increase exposure.
