A new IU study examining effects of low-level developmental lead exposure in mice could explain why some people dependent on alcohol return to using.
The study, published in Neuropharmacology, looked at whether developmental lead exposure can increase the propensity to relapse to alcohol consumption in mice. The researchers also looked at the effects on the expression of synaptic and non-synaptic glutamate transporters — regulators of brain motivation and reinforcing circuits — in brain regions associated with drug addiction.
“Our data in mice suggests that early life, low-level lead exposure does not lead to the development of an alcohol use disorder in adults per se,” said Stephen Boehm, professor in the Department of Psychology at IUPUI. “However, it does alter brain circuits in such a way that once a dependency is developed, it makes it harder to refrain from turning back to alcohol.”
Scientists at the NOAA Northeast Fisheries Science Center have developed an unusually rich picture of who is eating whom off the Northeastern United States. The findings, published recently in Fish and Fisheries, provide a close look at fish feeding habits for 17 fish species, predators, and their prey.
The predators are divided into 48 predator-size categories, and 14 prey species. Fish predators included Atlantic cod, Atlantic herring, haddock, goosefish, pollock, spiny dogfish, winter flounder, and yellowtail founder among others. Prey species included forage fish, squid, zooplankton, shrimp-like crustaceans, shellfish, brittle stars, sand dollars, and sea urchins.
“We have the largest, continuous dataset of fish feeding habits in
I happened to see my wife’s screen time analytics on her phone recently. She’s spending an average of over seven hours a day on her phone.
And she’s not alone.
Global online content consumption is soaring in 2020, a new study of over 10,000 people in five countries says. The previous normal was just over three hours, but now my wife is — at least in this respect — completely and totally average. Average daily time spent consuming content is now six hours and 59 minutes, which includes phone, TV, and other forms of digital media.
The obvious question: if that’s average, how much screen time are the outliers getting?
Clearly, eight, nine, even ten hours a day. In fact, as a different study I covered a month ago
