I wonder what the motor's performance is like on high grade roads?

Submission + - SPAM: Study finds alarming levels of 'forever chemicals' in US mothers' breast milk 2
Hmmmmmm writes: A new study that checked American women’s breast milk for PFAS contamination detected the toxic chemical in all 50 samples tested, and at levels nearly 2,000 times higher than the level some public health advocates advise is safe for drinking water.
PFAS, or per and polyfluoroalkyl substances, are a class of about 9,000 compounds that are used to make products like food packaging, clothing and carpeting water and stain resistant. They are called “forever chemicals” because they do not naturally break down and have been found to accumulate in humans.
They are linked to cancer, birth defects, liver disease, thyroid disease, plummeting sperm counts and a range of other serious health problems.
The peer-reviewed study, published on Thursday in the Environmental Science and Technology journal, found PFAS at levels in milk ranging from 50 parts per trillion (ppt) to more than 1,850ppt.
Though researchers are concerned by the findings, newborns are difficult to study so there has not been a thorough analysis of how PFAS affect them, said Sheela Sathyanarayana, a co-author of the study and pediatrician with the University of Washington.
But she added that studies of older children and adults have linked the chemicals to hormonal disruptions and suggests PFAS harm the immune system, which could be especially problematic for infants because breast milk bolsters their immune system.

Submission + - Astronomers Search For Answers To Origin Of Interstellar Visitors (bbc.com)
boudie2 writes: Since the first sighting in 2017 of a space anomaly named
Oumuamua, Hawaiian for "a messenger from afar arriving first"
(pronounced oh-moo-uh-moo-uh) there has been much speculation
about it's origin and formation. In an article from the BBC
they give some background and tell us what astronomers have
discovered about it. "Tumbling through space at 57,000mph
(90,000 kmph), the object is thought to have come from the
direction of Vega, an alien star that resides 147 trillion
miles (237 trillion km) away." They go on to say that
"Oumuamua has not yet been definitively classified as a
comet or an asteroid – it might be something else entirely."
There is hope that a recently constructed observatory at the
top of Cerro Pachon, an 8,799 foot high mountain in Chile
that will be equipped with the "largest digital camera ever
constructed for the field of astronomy" will help provide
answers.
