Being Gay Was the Gravest Sin in Washington
O n November 23, 1963 , the morning after he swore the oath of office in an impromptu ceremony aboard Air Force One, President Lyndon B. Johnson called Bob Waldron to commiserate about the colossal burden that had just been placed upon his shoulders.

When Your Vote Doesn't Matter, Try Switching Ballots
Pundits and voters of all stripes lament just how extreme, polarized, and ideological American politics has become. But such grievances rarely come with advice for how ordinary people can address this problem, other than by voting for their preferred political party's candidates in general elections. Even that advice isn't very helpful: Voters in many parts of the country do not have the chance t

The People Who Hate People
S ome propositions are so obvious that no one takes the time to defend them. A few such propositions are that human life is good, that people can and often do provide more benefits to the world than they take away, and that we should design society to support people in leading lives that are good for themselves and others. These ideas came under attack, sometimes subtly and sometimes overtly, by

Life's First Peptides May Have Grown on RNA Strands
The idea that life's deepest, oldest roots were laid down by RNA molecules that evolved ever more complexity has dominated the origins-of-life field for the past few decades, reigning over competing theories that started instead with peptides or DNA. But recently, the field has shifted toward theories that include more than one protagonist. One that's gained particular momentum is the idea that..

Don't Look Away From Philip Guston's Cartoonish Paintings of Klansmen
A nybody who has seen one of Philip Guston's representational paintings knows the rest of them.

Human influence is the culprit for warm and wet winters in northwest Russia
During the smoldering hot days of summer, people miss the cool breeze of winter. Both intense cold and heat are unbearable, but warm and wet winters also lead to problems. For example, northwest Russia experienced the warmest and wettest 2019/20 winter on record since 1902. Because of this, the permafrost melted, raising the risk of floods and landslides in the following spring, as well as rapid m

What's Your Biological Age? A New 'Aging Clock' Has the Answer
How old are you, really? It seems like a simple question. It's based on when you're born. Yet we all know people who seem much younger than their chronological age. They have radiant skin and hair. They seem sharper than their age would suggest. They're highly active with astonishing energy. Why? Studies have repeatedly shown that cells, tissues, and people have a "biological age" that may or may

Big Success for Anti-obesity Drug
When I saw this headline on an article in The Week magazine, I was impressed.
