RIP Matt Von Ohlen
Police are currently looking for the driver of the black Camaro who knocked Von Ohlen off his bike then ran over him, then sped away. If they find him/her, may give him/her a bike safety pamphlet.

Thompson, Rivara and Thompson M.D.s, “Effectiveness of Bicycle Safety Helmets in Preventing Head Injuries,” JAMA, 1996.
This is probably the most cited of all helmet studies. It appeared at a time when the CPSC was considering the possibility of making new standards for little kids’ helmets. On one side of the discussion, engineers and advocates who thought child and toddler helmets should be made softer to protects kids from the type of head injuries they are most likely to suffer while bicycling. On the other side, helmet company reps who argued that kids didn’t need new standards or softer helmets.
Thompson, Rivara and Thompson’s “Effectiveness of Bicycle Safety Helmets in Preventing Head Injuries” came along just in time to lend the industry some apparent scientific legitimacy to their argument.
The study concludes like this: “Based on our study, changes in helmet certification standards or the design of helmets particularly for younger age groups are less likely to result in major benefit.” The mention of kids’ helmet standards–“particularly for younger age groups…”–comes out of the blue at the end of the paper.
This is quite strange because, earlier in the document, the authors revealed that the study, which included over 3,000 crashed cyclists, included only one helmeted brain-injured subject under 6 years of age. Because of this almost total lack of data, the authors admit that their study cannot estimate any protective effect of helmets for this age group.
Hmm. But in the conclusion, which is the only part of the privately held document that journalists or 99% of the public will ever read, the authors do just that. They claim that helmets give the same protective benefit “to cyclists of all ages…” And then they go out of their way to say that bit about little kids not needing better helmet standards.
I don’t know about you, but I think it’s very interesting that the particular age group that receives the most attention in the conclusion, is the one that received the least attention when collecting data. This seems to be a really smarmy piece of work.

…except for PR purposes.
“We’d been hearing that the athletes biological passport, which is the latest tool in the fight against doping, is not quite as sensitive as people might want to think,” he says. “What we decided to do, with me being an amateur athlete, is put this passport to the test.”
He writes:It would last for 14 weeks, and have three phases. I would have my blood taken once a week and sent off to a lab for analysis. A doctor would monitor my health throughout.Baseline – weeks 1-3: establish what my “normal” blood levels are. Performance test at end of week 3Loading – weeks 4-10: undergo a program of between 2-3 micro-dose injections of EPO per week. Each injection would be supervised. Performance test at end of week 10Washout – weeks 11-14: critical phase of the experiment, when I stop taking EPO and the passport is meant to be most effective.The plan was to collect 14 blood analyses and have them put through the biological passport software to see if it would catch me.
But he wasnt testing to see if EPO works. He knows it works. He wanted to see if he could get away with doping. He took blood samples each week and sent them to have them analyzed and placed into a biological passport. “And the truth is, I was able to sail through the tests. I got away with it,” he says.

The crowd cheered. Bugles rang out. Within a year, Dobbins promised, something similar to Columbus’s short route to the Orient would rise above the hills of the Los Angeles basin. His “Cycleway” was designed to swiftly and conveniently transport people between a pair of key urban centers: the old colonial plaza in Downtown Los Angeles, and Pasadena, the burgeoning, modern suburb to the north that then rivaled the older city in size and ambition. The Dobbins route—which neatly anticipated and presaged the automotive freeways that now stretch across the region—would be a modern marvel. It would boast a state-of-the-art toll-collecting system. It would be elevated fifteen feet above the ground; the limited access would ensure that traffic flowed smoothly. “It can be said,” wrote the Los Angeles Times of the ground breaking, “that none of the new Southern California enterprises will …be more certain of financial success. The wheel must have a path of its own between these two cities.”

He didn’t go on Twitter about it.
After the war Bartali never spoke of his underground work during the German occupation. Hence many of his courageous endeavors remain unknown. Sara Corcos, who worked for the CDEC Centro di Documentazione Ebraica Contemporanea in Milan, told her niece, Shoshan Evron, the daughter of Rabbi Nathan Cassuto, that she had met Gino Bartali after the war. He emphatically refused to be interviewed, and said that he had been motivated by his conscience and therefore did not want to have his activity documented. Only when Corcos told him that she was related to the family of Rabbi Cassuto, a deeply moved Bartali agreed to speak, on condition that she would not record him. In the conversation that followed, Bartali told Corcos about the forged documents and about his role in distributing them.
