I spent a lot of time here. 20 years ago. Often referred to their example.
For many years, scientists have been puzzled by the behavior of Pacific Northwest fish-eating killer whales, who have been seen harassing and sometimes killing porpoises without eating them.
A study recently published in Marine Mammal Science, co-led by Deborah Giles of Wild Orca and Sarah Teman of the SeaDoc Society, a program of the UC Davis School of Veterinary Medicine, looked at more than 60 years of recorded interactions between Southern Resident killer whales and porpoises in the Salish Sea to better understand why they exhibit this behavior.
New research links menopause to cognitive deficits and brain atrophy, emphasizing the role of estrogen receptor beta in astrocytes. Findings from female mice studies suggest potential treatments targeting ERβ for improving cognition and reversing brain changes in menopause.

Longevity drugs for our canine companions are moving closer to reality. They also raise questions about what it might mean to succeed.
Interesting views from someone who teaches the subject.
The Food and Drug Administration on Monday approved the first treatment for people with desmoid tumors, a localized cancer that invades soft tissue and muscle.
This study discusses evidence anionic nanoplastic contaminants promote α-synuclein aggregation, observed in diseases like Parkinson’s. However, these are early findings, and there haven't been studies done in humans yet.

A team of paleontologists and biologists from Hokkaido University, Hokkaido University Museum, North Carolina State University and the Mongolian Academy of Sciences, has uncovered a previously unknown species of dinosaur that appears to have slept in the same position as modern birds.
The dossier was so unsettling, one neurologist revealed, that he couldn’t sleep after reading it. It contained allegations that an experimental drug meant to curb damage from stroke — and eyed up for regulatory fast-tracking for fulfilling an unmet medical need — might instead have raised the risk of death among patients receiving it.
The dossier, assembled by whistleblowers and obtained by an investigative journalist, was recently submitted to the US National Institutes of Health, which is finalising a $30mn clinical trial into the medicine. The whistleblowers allege that the star neuroscientist driving the research, Berislav Zlokovic from the University of Southern California, pressured colleagues to alter laboratory notebooks and co-authored papers containing doctored data. The university is investigating; Zlokovic is, according to his attorney, co-operating with the inquiry and disputes at least some of the claims.
The facts of this particular case, set out in the journal Science last week, are yet to be established but research is fast becoming a catalogue of mishaps, malfeasance and misconduct. Rooting out mistakes and manipulation should not have to depend on whistleblowers or dedicated amateurs who take personal legal risks for the greater good. Instead, science should apply some of its famed rigour to professionalising the business of fraud detection.
just science related topics.
