Jason Semprini was excited about his research on policies mandating that elementary school students receive the human papillomavirus vaccine. HPV causes most cases of cervical cancer, but counterintuitively, Semprini found that mandates don’t do that much to reduce the overall rate of cervical cancer in a population. That’s odd, but it's also not completely surprising—we know that mandating a vaccine can motivate some people to find ways to avoid it.

Semprini wrote up the study and submitted the manuscript to a journal, where it was sent out for peer review, a long-standing process through which other researchers in the field assess the validity of research and make a recommendation on whether or not it should be published. This is usually done anonymously and on a volunteer basis.

In this case, the reviewer did not share Semprini’s excitement. That may have stemmed from a misunderstanding of the study’s central message: The reviewer mistakenly thought Semprini was questioning whether the HPV vaccine itself prevents cervical cancer rather than studying the effectiveness of a policy meant to increase vaccination rates. “There’s a very big difference there,” said Semprini, who is a health economist at Des Moines University.

In the mid-'90s, the web was exploding, but finding anything of actual value on it felt like an elaborate negotiation with whatever proto-search engine happened to be standing closest to the door. Unlike now, when Google is widely seen as both portal and gatekeeper, sites like AltaVista, Lycos, Excite, HotBot, and Ask Jeeves promised to tame the chaos, each with its own suite of quirks, charms, and flaws.

The real story of pre-Google search is not that early engines were inferior. It's that they reflected a different Internet entirely, one where directories mattered, crawling was still an art, ranking was fragile, and the idea of “search” had not yet hardened into a single dominant interface.

A different kind of web

The first thing to remember about the pre-Google Internet is that there was no built-in assumption that you could search for everything. Many users found pages through Yahoo-style directories, bookmarks, newsgroups, email signatures, and links from site to site because the web was still small enough that human organization could compete with machine indexing. It was an era of Wild West-style discoverability. Search engines existed, but they were only one part of a larger ecosystem that blended curation and accident.

The Infinite Machine Olto is a great electric scooter, one with an overall layout that echoes the classic Vespa. It's comfortable, and it accelerates well, handles nicely, and has a capacious battery. It has a rugged design that seems capable of handling a lot of abuse, but it also comes with thoughtful touches and security features that mean you can park it anywhere with confidence. And it provides all that at less than half the cost of its full-featured stablemate, the P1 scooter.

The reason is that the Olto is also a bicycle. Sort of.

This may technically be a bicycle, but it's not one you'd ever want to pedal. While you can set it to operate as either a Class 2 or Class 3 e-bike, it works best when the pedals are both locked in a forward position, acting as footrests. The Olto was designed to provide riders with the experience of a scooter while still allowing them to take advantage of the growing bike lane networks in many urban areas across the country.

Every so often, I’ll be piloting some sensor-laden, software-defined press car down a dark stretch of highway when an oncoming driver’s high beams arrive like a targeted retinal strike, an involuntary reminder that modern automotive lighting has entered its own lumen arms race.

Anyone who has driven at night in the last few years knows what I'm talking about: A modern crossover crests a hill in the opposite lane, and the cabin briefly fills with enough cold-white light to suggest a police helicopter has joined traffic. The obvious assumption is that drivers are simply leaving their high beams on more often, but the reality is more complicated.

An old problem

Before cars became the modern mode of transportation, horse-drawn carriages used oil lanterns to light the way, as roads were largely unlit outside of towns and cities. These lanterns weren’t particularly bright, though, meaning that after-dark collisions and near-misses were common.

Thierry Rignol is furious at Yale.

Rignol paid Yale $208,500 in tuition for its Executive MBA program. But after he was accused of cheating, the school suspended him for a year and gave him an F in the course Sourcing and Managing Funds.

This happened despite the fact that Rignol was a "top student, on track to graduate first in his class," he says. As a result, Rignol missed out on being named class valedictorian, an honor he claims to have earned "under Yale's own stated criterion."
