Arnold Barnett, a statistician at the Massachusetts Institute of Technology who has studied airline safety, tells NPR that from 2018 to 2022, the chances of a passenger being killed on a flight anywhere in the world was 1 in 13.4 million. Between 1968 to 1977, the chance was 1 in 350,000.

"Worldwide flying is extremely safe, but in the United States, it's extraordinarily so," Barnett said.

In the U.S., there has not been a fatal plane crash involving a major American airline since February 2009, though there have been a handful of fatalities since then.

Brickhouse, who has studied aviation safety for over 25 years, often tells people that the biggest risk of any air journey tends to be driving to the airport.

More than 40,000 people are killed on U.S. roads each year.

"Aviation remains the safest mode of transportation," he says.

No. They do both, and that is directly shown in this study and in other studies. They eliminate many types of injury and make others less frequent.

False. Helmets are shown to reduce concussion and other head injuries in sport.

For example:

https://ufhealth.org/news/2021/headgear-significantly-reduce...

Female high school lacrosse players are significantly less likely to sustain concussions and other injuries if they wear headgear, a landmark study led by University of Florida Health researchers has found.

Girls who play the sport in states that don’t require headgear had a 59% higher concussion rate than players in Florida, the only state with a headgear mandate. The researchers also found lacrosse games were more hazardous than practices: Concussions were 74% higher during competition among players in states without headgear requirements when compared with Florida players.

Those details emerged from data collected during 357,225 games and practices in Florida and other states during three seasons from 2018 to 2021. The findings were presented today at the American Academy of Pediatrics national conference

Developmental fluoride neurotoxicity: an updated review

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6923889/

Conclusion

The recent epidemiological results support the notion that elevated fluoride intake during early development can result in IQ deficits that may be considerable. Recognition of neurotoxic risks is necessary when determining the safety of fluoride-contaminated drinking water and fluoride uses for preventive dentistry purposes.

Michael Lewis wrote about this story in his book “Next”. Also in the New York Times magazine. The articles and book have some pretty interesting discussion and opinion about this case.

Thanks!!! @dang - This should be the primary headline link

Sounds so hard.

I’ve experienced that a moderate or intense exercise regimen can help a lot with sleep.

If she hasn’t tried therapies directed at trauma and recovery that may also be helpful.

This is an interesting question and I wonder if you could feed the whole dump into an LLM like ChatGPT and have it give you a valid answer to your question. I’m gonna try it later. If anyone does have a manual or automated answer let us know!

That was my first reaction as well. Very much inspired by the wright work. It does look cool! I wonder about noise levels with all the hard surfaces and open space.

I don’t understand what the cursors and highlights are supposed to show us.

Maybe they could just put in flashing text plus a flashing background plus a microwave attack on the reader.

Just watch how expensive not fixing it will be.

So true thanks for posting.

Minions must return to office and support CRE valuations!

Spoken like someone who doesn’t know how buildings, bridges, or dams are built.

Thanks for posting your experience. I haven’t tried duolingo. Do you think it’s possible that the 18 months helped prep you for classroom learning , vocabulary etc?

How intense was your classroom learning and how much time per week?

I took years of French in school and would like to learn Spanish.

Some thoughts:

- aerodynamics make a huge difference. Even in a light trailer. Especially if it has a significant frontal area. That’s for sure.

- towing a trailer may reduce energy recovery from regenerative braking.

- when towing, power requirements on the motors and batteries may move them away from optimal efficiency and design points (that’s a guess).

- the model Y is probably not significantly more aerodynamic than comparable sized car models. But it’s a lot more aerodynamic than a trailer.

Dystopian is “water was free so the big farming business pumped the aquifer dry and exported the agricultural goods. Now people here have no water and the land is a desert”.

This stuff is economics 101.

The full quote is:

“”Soren Bjorn, a senior executive at Driscoll’s who in January will become the chief executive, said in an interview that he “absolutely” sees the region as a model of water pricing that could be replicated in water-stressed regions from Texas to Portugal. “Water can’t be free anywhere, because you can’t run a sustainable water supply without pricing it,” he said. “That would apply to the globe." “”

I should add that I’m glad the author wrote this as an account of their family experience and I have great sympathy for them, having seen similar experiences up close.

Great article but the author is missing the fact that this is all designed on purpose. The insurance system is designed around a consistent strategy called “don’t pay out”.

The USA spends more GDP on healthcare than any country on earth and the insurance companies are immensely profitable.

Every company involved is making money off the status quo and wants to maintain the current system. when a patient comes along who isn’t desirable and profitable, they’re screwed.

This is all well documented in research about modern USA healthcare and health economics. None of this is an accident and the fact that this situation persists should be a national embarrassment.

Hi. It would be interesting to read these military studies could you provide some citations or links?

Are they published in reputable journals?

You should read the description of the accident:

“Over the next few days the resulting man-made sinkhole swallowed up the oil rig, 11 barges, a tugboat, 35 hectares of land and part of a house. A canal that drained the lake into the Gulf of Mexico began flowing backwards as the water level fell, briefly creating the tallest waterfall in Louisiana, while muddy geysers erupted from mine shafts. Somehow, all 50 people working in the mine managed to get out ahead of the rising floodwaters.”

This page has detailed maps and aerial views with annotations showing directions of groundwater flow and some good discussions.

There are photos and more info here.

Definitely needs a map of the dam site and photos of the dam itself!!

This is a great article. Very interesting. Thanks for posting!

I recently developed a new interest in optics and it’s cool to see this posted on HN.

It links to his author page. Are you able to tell if the journal images are all taken from a book? Which book? There are multiple books on the Amazon page.

If you click on the Tab 'FRANCES CHANGED MY LIFE' it shows that band members John and Zoe have a daughter Frances. They're raising money to fund research into Frances' rare neurological disease:

"Frances has a rare genetic mutation that causes a degenerative disease called DHDDS. In the last few years, breakthroughs in medical science have made it possible to develop a treatment. Unfortunately, it's extremely expensive. We are telling Frances’story in hopes of raising enough donations to fund her treatment."

Hopefully the HN traffic boost can help drive some donations and new research into treating neurological diseases. Donate!

Thanks this is pretty interesting!

Re: “car crash”, crash is the correct “real language”. The use of “accident” implies a lack of responsibility and that car crashes cannot be prevented or reduced. That isn’t true. Many studies show that crashes can be reduced via better engineering, road design, etc.

Calling it an accident definitely seems like softening the language.

"it is not clear if there is a way."

This is what the car lobby wants you to think. The transformation to a better and more livable city free from overwhelming car traffic is closer and faster than you imagine. The primary challenge is the power of the car-industrial complex both inside and outside government and the continued work to destroy and hobble other forms of transit.

The strange fate of a group of skiers in the Ural Mountains has generated endless speculation.

If you find these types of 'disappeared in the wilderness' stories interesting, there's a really interesting one about a group of skiers in the Ural Mountains:
