#Jacob van Ruisdael - Paisagem com uma vila a distância 1646 (Windows)
Os estudiosos da arte não consideram esta pintura uma obra-prima, nem mesmo uma das melhores obras do artista. Isso não é muito surpreendente, dado quem é o pintor: Jacob van Ruisdael é considerado por muitos como o maior paisagista da história da Holanda. O que pode ser surpreendente é que Van Ruisdael tinha apenas cerca de 18 anos quando terminou esse trabalho ambicioso. Também impressionante? "Paisagem com uma Vila à Distância" é apenas uma das 15 pinturas de paisagens conhecidas que o artista produziu somente em 1646. Seu talento é aparente aqui nesta obra de óleo sobre madeira, com sua grande escala, reprodução detalhada da folhagem exuberante e representação habilidosa de uma aldeia no horizonte. Esse trabalho inicial mostra um gênio em crescimento começando a desenvolver os músculos criativos.

"Paisagem com uma Vila à Distância" está na coleção do Metropolitan Museum of Art na cidade de Nova York.

A Massive Observation
According to new observations, the heaviest neutron star is 20,000 light-years away from Earth and weighs 2.35 times as much as our sun. The record-holder owes its success to gas falling from a nearby orbiting star, reports Ken Croswell for Science News. What goes on in the hidden interiors of these dense and massive stars remains a mystery. Physicists have wondered if their cores consist of squishy and exotic “quark” matter, but new data released last year casts doubt on that model, as Jonathan O’Callaghan reported for Quanta.


Look Who’s Talking
In the largest study of its kind, researchers proved that “baby talk” is much the same everywhere. Spanning 18 languages and six continents, the new research confirmed that adults adopt a sing-songy voice called “parentese” when singing or speaking to babies, reports Oliver Whang for The New York Times. Parentese is thought to make it easier for babies to learn language. When babies imitate the sounds they hear, they’re using vocal learning — an ability possessed by only a few species, notably humans and songbirds. In 2018, researcher Erich Jarvis chatted with Jordana Cepelewicz for Quanta about his work on vocal learning in songbirds and why it could help reveal how the human capacity for language evolved.

Today's selection -- from Persians: The Age of the Great Kings by Lloyd Llewellyn-Jones. The Persians ruled the largest of all ancient-world empires:

"This history [of Persia] uses genuine, indigenous, ancient Persian sources to tell a very different story from the one we might be familiar with, the one moulded around ancient Greek accounts. This story is told by the Persians them­selves. It is Persia's inside story. It is the Persian Version of Persia's history./.../

Every spring, migratory birds arrive in the continental United States from south and central America to breed. But precisely when they arrive each spring varies from year to year. In a NASA-led study published in the Bulletin of the American Meteorological Society, scientists have linked this variability to large-scale climate patterns originating thousands of miles away./.../

A New Radio Hit
Astronomers working with the CHIME telescope in Canada have detected the longest fast radio burst ever, clocking in at about 3 seconds. The bursts appear to feature a rhythm like a heartbeat, reports Ben Turner for Live Science. Fast radio bursts are mysterious radio signals, usually from faraway galaxies, whose origins remain under study. In 2020, researchers tracked the first fast radio burst detected within our own galaxy back to a magnetar, as Shannon Hall covered for Quanta.

That Smells Like It Looks Good
Researchers recently uncovered the network of brain connections behind a dog’s powerful sense of smell. The map includes an unexpected tract not yet found in other animals that runs from the olfactory bulb to visual cortex, reports Laura Sanders for Science News. Smell has been one of the least understood senses. But in 2021, neuroscientists unveiled for the first time how olfactory receptors in insects recognize smells when odor molecules bind to them, as Jordana Cepelewicz reported for Quanta in 2021.
