"The Tropical Atlantic Ocean, the Mediterranean Sea, and southern oceans recorded their highest OHC observed since the 1950s. Associated with the onset of a strong El Niño, the global SST reached its record high in 2023 with an annual mean of ∼0.23°C higher than 2022 and an astounding > 0.3°C above 2022 values for the second half of 2023."

William Herschel discovers Titania and Oberon, two moons of Uranus #OTD in 1787.

Titania and Oberon are named after the queen of the fairies in Shakespeare's A Midsummer Night's Dream. Titania´s orbit lies inside Uranus's magnetosphere while Oberon´s orbit lies partially outside Uranus's magnetosphere. For nearly 50 years following their discovery, Titania and Oberon would not be observed by any instrument other than Herschel's. via @wikipedia

"Dating from the Late third millennium BCE, the ramparts of Khaybar were probably built by indigenous populations as they settled down and ostentatiously demarcated their oasis territory. These ramparts lasted for several centuries before being dismantled or replaced by more recent structures." doi.org/10.1016/j.jasrep.2023. @archaeodons

Swedish biologist & physician Carl Linnaeus died #OTD in 1778. He was the 1st to frame principles for defining natural genera & species of organisms & to create a uniform system for naming them (binomial nomenclature). Linnaeus published Philosophia Botanica in 1751. The book contained a complete survey of the taxonomy system he had been using in his earlier works. Species Plantarum contained 1,200 pages & was published in two volumes; it described over 7,300 species.

🚨🚨 GROUNDBREAKING NEW FINDING ALERT 🚨🚨

"As the main result, we find that OA is associated with higher citation diversity, i.e., OPEN outputs receive more diverse citations as compared to CLOSED outputs. We refer to this phenomenon as OA citation diversity advantage."

Yesterday, a major new study was released showing massive numbers of micro/nano plastic particles in bottled water. Here's that study:
pnas.org/doi/10.1073/pnas.2300

Today, bottled water lobbyists released a predictable, biased, response:
1. Stop picking on bottled water, plastic particles could be everywhere;
2. Maybe they're not bad sooo for human health, we don't know.
3. The methods used are new, so who really knows if the results are valid.
4. Keep drinking bottled water.
