‘Proto' Review: Ancient Speech, Carried Far
In 'Proto,' Laura Spinney details the centurieslong effort to reconstruct Proto-Indo-European (PIE), what linguists believe to be the mother tongue of a diverse constellation of languages from Sanskrit to Gaelic. Ms. Spinney, a journalist whose previous book, 'Pale Rider' (2017), charted the worldwide spread and cultural impact of the 1918 influenza epidemic, here demonstrates how the language of those humble, preliterate nomads radiated across the prehistoric world and how their myths and rituals may have helped sow the seeds of modern civilization. It's a comprehensive and at times dizzying account that draws from the latest archaeological and genetic research to craft a compelling portrait of a people thought lost to time.
Thinkers from Dante to Leibniz had long noticed peculiar similarities among languages from far-flung places. But it wasn't until 1786, when William Jones, a British judge stationed in India, proposed a link among Latin, Greek and Sanskrit, that the idea of a common lingual ancestor was taken seriously. Since then, researchers have developed a hypothetical vocabulary for PIE that consists of about 1,600 word stems, which form the basis of many of our most common words. For example, 'daughter' in English, 'thugátēr' in Greek and 'duhitár' in Sanskrit are all believed to have been derived from a common PIE root that was transformed by local speech patterns over time. In this, Ms. Spinney sees 'a seam that connects east and west; a fiber stretched taut between them that thrums in all of us.'
While it's not clear precisely why PIE was able to establish such a wide domain, Ms. Spinney suggests that commerce likely played a role. 'In all of recorded history,' she writes, 'you'd be hard-pressed to find a single example of human beings trading in high-value goods without an effective means of communication.' By 4500 B.C., commodities such as gold, copper and salt were moving along a vast trade network centered on the Black Sea. PIE may have first spread thanks to its association with these valuable luxuries.

Researchers discover 2,500-year-old honey residue in ancient bronze jars
Researchers recently made a sticky discovery. They found 2,500-year-old honey, sealed in a vessel and buried underground for nearly three millennia. The residue was found in bronze jars at an underground shrine in Paestum, an ancient Greek settlement in modern-day Campania, Italy. The artifacts date back to the 6th century B.C. The jars were first found by archaeologists in 1954, but the residue in them has eluded experts – until now. In a study published by the American Chemical Society on July 30, experts concluded that the waxy residue was once honey. Luciana Carvalho, a research associate at the University of Oxford, told Fox News Digital the substance bears little resemblance to the golden honey in most modern-day cupboards. "Ancient honey was quite different from the clear, smooth honey we buy today," she noted. "There was no ultra‑filtration, no pasteurization and no synthetic pesticides in the landscape." The chemical results "strongly" suggested that the jars held raw honeycomb, rather than a blended product like most modern honey. "If honey had been mixed with milk, for example, we would expect to see extra fatty acids in the residue – and we don't," she said. But the raw honeycomb has dramatically changed over the millennia. Along with fellow researchers Elisabete Pires and James McCullagh, Carvalho found that the sugar gradually became dark and acidic. "After 2,500 years, almost all the original sugars have broken down [and been] eaten by microbes, so the residue isn't sweet anymore." "[The] sugars slowly reacted with proteins in a kind of slow-motion browning process, similar to what happens when bread bakes, turning it darker and more acidic," she said. Because of that, the remaining residue isn't exactly pleasant to eat, according to the expert. "What survives now is a waxy residue with a slight tang and virtually no sweetness," Carvalho noted. "After 2,500 years, almost all the original sugars have broken down [and been] eaten by microbes, so the residue isn't sweet anymore." As for the vessels, Carvalho said the bronze jars have cork discs that seal their necks, which points to "careful storage of something valuable." The copper-alloy jugs were found in a sealed, underground shrine, suggesting that they were left there as part of a ritual. "Inside, the residue clung to the bottoms and sides, exactly what you'd expect if raw honeycomb had been placed inside and slowly dried out over centuries," she said. "We hope our approach will be used to identify honey residues in other museum collections so we can learn more about ancient beekeeping and the role of honey in diet, medicine and ritual life." Researchers in the 1980s previously believed that the honey was a mixture of wax, fat and resin, with Carvalho noting that past research was limited by less precise tools. "Those methods were great for detecting fats and waxes but couldn't easily pick up sugars or proteins without extra chemical steps," she said. "In our study we used multiple modern techniques designed to detect different types of molecules, including sugars and proteins, even if these are present at trace levels, with instruments far more sensitive than anything available in the 1980s." She also noted that the discovery had strong collaboration from multiple groups, including museum curators, conservators and specialized scientists. "We hope our approach will now be used to identify honey residues in other museum collections so we can learn more about ancient beekeeping and the role of honey in diet, medicine and ritual life," Carvalho said. The latest research adds to a number of ancient food-related discoveries this year, which are extremely rare occurrences. In Guam, 3,500-year-old rice was recently found, making it the earliest known evidence of rice in Remote Oceania. Earlier in 2025, archaeologists uncovered a well-preserved loaf of ancient bread in Turkey, dating back to the Bronze Age.

Ongoing meteor shower could produce exploding fireballs of color and light this week
While they are already glittering across the evening sky, the most popular meteor shower is about to reach its peak, with a chance of large fireballs exploding against the black backdrop of night. The Perseid meteor shower has already streaked across the sky since July 17 and will continue until Aug. 23, but they should reach peak speed and volume between Aug. 12 and 13, according to NASA. The best time to check out the Perseids is during the pre-dawn hours, but astronomers suggest viewing them as early as 10 p.m. As the Perseids appear, they typically leave behind long 'wakes,' or brief glows of light and color behind them, the space agency stated. The meteor shower typically has around 25 meteors fly through the sky per hour, but as many as 50 to 100 can be seen 'Perseids are also known for their fireballs,' NASA stated on its website. 'Fireballs are larger explosions of light and color that can persist longer than an average meteor streak. This is due to the fact that fireballs originate from larger particles of cometary material.' For these reasons, NASA said that astronomers consider the Perseids as the best and most popular meteor showers of the year. So, where in the night sky can stargazers spot the Perseids? The shower's radiant point, or the placement of where a celestial object is in the night sky, is in the direction of the constellation Perseus, NASA stated.

A rare ‘Black Moon' will appear in the sky this month. Here's when
While there is the expression 'Once in a blue moon,' once in a while, there is a Black Moon too. Later in August, a rare Black Moon will be seen — or rather, hidden — in the night sky. A Black Moon is the moniker for a third new moon out of four in an astronomical season, instead of the usual three, as Time and Date described. The western half of the Western Hemisphere is expected to 'see' the Black Moon starting before 12 a.m. on Aug. 22, according to Time and Date. For the rest of the world, the Black Moon will occur after 12 a.m. on Aug. 23, including for the central and eastern United States. Black Moons happen once every 33 months, with the next one expected on Aug. 20, 2028, when it is also expected to be a supermoon, Time and Date stated. The previous Black Moon was on April 30, 2022. In the lunar cycle, new moons take place roughly every month, according to NASA. As people likely know, the moon is invisible in the night sky when it reaches its new moon phase. The illuminated side of the moon faces the sun while the night side faces Earth. Given that a new moon means the night sky is free from the moon's illumination, the night of a Black Moon is a perfect time for stargazing and using a telescope to view the planets and stars in the sky.
