“Because of this male-specific effect, we investigated the effects of MPH through the paternal line and observed the same behaviors in several generations of their descendants not directly administered the drug.”


Summary: A new study of male guppies reveals behaviors affected by methylphenidate hydrochloride (MPH), an active ingredient in common ADHD medications, can be passed along to future generations.

By studying guppies, scientists at the University of Toronto and Florida State University found that behaviors affected by methylphenidate hydrochloride (MPH) – the active ingredient in stimulants such as Ritalin and Concerta used to treat ADHD—can be passed along to several generations of descendants.

“We exposed male and female Trinidadian guppies to a low, steady dose of MPH and saw that it affected the anxiety and stress-related behavior of males, but not females,” said Alex De Serrano, a Ph.D. candidate in the department of ecology and evolutionary biology (EEB) in the Faculty of Arts & Science and lead author of a study published recently in Scientific Reports.

The space agency is launching two missions to study Venus’ atmosphere and geological history.


“I did a lot of screaming and jumping up and down,” Grinspoon tells Inverse. “I scared my dog.”

On Wednesday, NASA selected both DAVINCI+ and another Venus mission, VERITAS, to study the planet’s atmosphere and geological history. It will mark a return to Venus after decades away.

By returning to Venus, it could answer questions both intriguing, like if Venus ever had the right conditions for life, and existential, like if Venus is a vision of our future.

Banner Smoked Fish Inc. is recalling 43 of its s moked fish products in all package sizes, all package types and all lots, because of a potential Listeria monocytogenes contamination.

The problem was discovered through FDA routine inspection, and the products were found to be processed under unsanitary condition.

The recalled smoked fish were distributed through retail stores and also online in the New York, New Jersey, Illinois, Pennsylvania, California, Florida, Nebraska, Arizona, Massachusetts, Maryland, Virginia, Nevada, Oregon, Wisconsin, North Carolina, South Carolina and Georgia.

This is a technological triumph.


Twenty-one years ago, researchers announced the first “draft” of sequencing the complete human genome. It was a monumental achievement, but the sequence was still missing about 8 percent of the genome. Now, scientists working together around the world say they’ve finally filled in that reclusive 8 percent.

If their work holds up to peer review and it turns out they really did sequence and assemble the human genome in its entirety, gaps and all, it could change the future of medicine.

A bit early, (or a lot late 🙂) but I love this post. Beverage warnings apply:


In a world where many blogs and websites are shutting down comment threads, I think we all need the occasional reminder of why we permit comments. Sure, you often learn something new from other people’s inputs, and sometimes get corrected when you step beyond the limits of your actual knowledge-base too far. But sometimes you read a comment that’s so brilliant, you just have to look up the commenter’s email, and beg them for permission to repost their work of art. This was one of those times.
