At 36, I am just old enough to remember when sunscreen wasn’t a big deal. My mom, despite being among the palest people alive, does not remember bringing it on our earliest vacations, or hearing any mention of sun protection by our pediatrician. The first memories I have of sunscreen are from the day camp that my brother and I attended in the 1990s, where we spent every day on a playground in the direct Georgia sun but were prompted to slather it on only once every two weeks, when we were bused to a community pool. On those days, mom dropped an ancient bottle of Coppertone, expiration date unknown, into my backpack, where I usually left it. In 2000, I started high school, just in time for the golden age of the tanning bed.

Mosquitoes are the world’s deadliest animal. Hundreds of thousands of deaths a year are attributed to mosquito-borne diseases, including malaria, yellow fever, dengue fever, Zika, and chikungunya fever.

How mosquitoes seek out and feed on their hosts are important factors in how a virus circulates in nature. Mosquitoes spread diseases by acting as carriers of viruses and other pathogens: A mosquito that bites a person infected with a virus can acquire the virus and pass it on to the next person it bites.

For immunologists and infectious-disease researchers like me, a better understanding of how a virus interacts with a host may offer new strategies for preventing and treating mosquito-borne diseases. In our recently published study, my colleagues and I found that some viruses can alter a mouse’s, and perhaps a person’s, body odor to be more attractive to mosquitoes, leading to more bites that allow a virus to spread.

The San Francisco School Board recently returned the admissions policy at Lowell, the city’s most prestigious public high school, to the merit-based system that it had used for more than a century. Thus ended a short-lived lottery introduced in the name of racial equity. The board also abandoned a campaign to erase “The Life of Washington,” a WPA-era mural at George Washington High School by the artist Victor Arnautoff. Arnautoff was a Communist, and his mural, which depicts slaves picking cotton at Mount Vernon, was intentionally subversive. But an earlier incarnation of the board had voted first to destroy it, then to cover it up, saying that removing it from view was a form of “reparations.” The board member Alison Collins had said, “This mural is not historic. It is a relic.”

The ad that signaled the coming catastrophe for democracy in North Carolina appeared just four days before the November 2012 election. As the ad opened, a woman’s voice wondered aloud whether voters “can trust Sam Ervin IV to be a fair judge.” Ervin, captured in black and white, looks shifty, moving his eyes back and forth before turning his head suddenly as if he is on the run. Ervin and his family, the ad announced, had donated to the campaign of the former Democratic governor, and later convicted felon, Mike Easley. The camera lingers on Ervin’s face as the ad explains that he went on to get a $100,000 state job; the portrait could be mistaken for a mug shot, were it not for his suit and tie.

Vancouver, British Columbia, is nothing short of a seafood paradise. Situated at the mouth of the formerly salmon-rich Fraser River, the city overlooks Vancouver Island to the west, and beyond that, the open Pacific Ocean. Long before it had a skyline or a deepwater port, this was a bountiful fishing ground for the Musqueam, Squamish, and Tsleil-Waututh peoples, who still depend on its waters for cultural sustenance. Today, tourists come from all over the world to taste local favorites, such as salmon and halibut, fresh from the water. But beneath these waves, things are changing.

Climate change is an intensifying reality for the marine species that live near Vancouver and for the people who depend on them. In a new study, a team from the University of British Columbia (UBC) shows one unexpected way that climate effects are already manifesting in our daily lives. To find it, they looked not at thermometers or ice cores, but at restaurant menus.
