Few harbingers of old age are clearer than the sight of gray hair. As we grow older, black, brown, blonde or red strands lose their youthful hue. Although this may seem like a permanent change, new research reveals that the graying process can be undone—at least temporarily. Hints that gray hairs could spontaneously regain color have existed as isolated case studies within the scientific literature for decades. In one 1972 paper, the late dermatologist Stanley Comaish reported an encounter with a 38-year-old man who had what he described as a “most unusual feature.” Although the vast majority of the individual’s hairs were either all black or all white, three strands were light near the ends but dark near the roots. This signaled a reversal in the normal graying process, which begins at the root.
In a study published today in eLife, a group of researchers provide the most robust evidence of this phenomenon to date in hair from around a dozen people of various ages, ethnicities and sexes. It also aligns patterns of graying and reversal to periods of stress, which implies that this aging-related process is closely associated with our psychological well-being. These findings suggest “that there is a window of opportunity during which graying is probably much more reversible than had been thought for a long time,” says study co-author Ralf Paus, a dermatologist at the University of Miami.

My impression is that the police in New York have tempered their initially confrontational approach to the protesters. There were no barricades or cars set up to entrap and enclose marchers. It seemed to me that, slowly, some lessons are being learned. But not everywhere — in Atlanta,

The signature of our current debate about free speech is that it is not primarily about protecting speech from the government. Rather, it is about the “culture of free speech.” It’s about intellectual openness and diversity as a cultural norm to be embraced by private individuals and private institutions.

To understand the strength of Putin’s position when it comes to defending Russian international interests (as opposed to domestic interests, where his deeply corrupt set-up is becoming increasingly unpopular), it is vital to understand that while Putin is obviously much more personally powerful than Western leaders, he is still the leader of the Russian foreign and security establishment — or as former Obama adviser Ben Rhodes dubbed the US equivalent, a blob.
Some years ago a friend brought us to see the town of Acitrezza in Sicily where, arguably, the first great neorealist film was made. La Terra Trema (The Earth Trembles) was, according to its director, Luchino Visconti, filmed with actors “chosen from among the inhabitants of this town: fishermen, girls, labourers, stonemasons, fish wholesalers”. The dialogue was Sicilian, very much a language in itself and coeval with Italian. Our friend told us that the woman who played one of the sisters, Lucia, who is seduced by the marshal Don Salvatore in the film, was afterwards rejected by her community and never found a husband because they believed she had become a whore. The story may be a kind of urban legend, but there are so many layers to it that it’s worth unpacking a little.
The Emancipation Proclamation, some forget, was not the sweeping, all-encompassing document that it is often remembered as. It applied only to the eleven Confederate states and did not include the border states that had remained loyal to the U.S., where it was still legal to own enslaved people. Despite the order of the proclamation, Texas was one of the Confederate states that ignored what it demanded. And even though many enslaved people escaped behind Union lines and enlisted in the Federal Army themselves, enslavers throughout the Confederacy continued to hold Black people in bondage throughout the rest of the war. General Lee surrendered on April 9, 1865, in Appomattox County, Virginia, effectively signaling that the Confederacy had lost the war, but many enslavers in Texas did not share this news with their human property. It was on June 19, 1865, soon after arriving in Galveston, that Granger issued the announcement, known as General Order Number 3, that all slaves were free and word began to spread throughout Texas, from plantation to plantation, farmstead to farmstead, person to person.

The sclera of the eye is devoid of pigment, which is why humans can easily follow where counterparts are looking. Researchers have long believed this facilitates glance-based communication. A team of zoologists based at the University of Duisburg-Essen (UDE) and the Anthropological Institute in Zurich is now challenging this traditional view in a new study. The researchers looked at communicative behavior and eye color in apes and question the proposed connection between the two phenomena. The results have just been published in Scientific Reports.
John Betjeman’s life at Oxford was complicated. He wrote poems and made friends, he discovered beauty and rejoiced in it, but he struggled academically, in part because of an impossible relationship with his tutor, who thought him an “idle prig” and did nothing to disguise his hostility. The tutor complained about Betjeman’s silly aestheticism in his diary, but didn’t confine himself to private musings: He treated Betjeman with open contempt, and when Betjeman needed a supportive letter from him, he wrote a rather obviously unsupportive one––which was one reason among several that Betjeman never managed to graduate. What the tutor did not realize was that Betjeman’s frivolous manner was a kind of protective carapace, a way to shield himself from suffering and emotional upheaval.
