When light shines through water, colors with longer wavelengths are absorbed by the water, with the longest wavelengths absorbed first. Blue and violet have the shortest wavelengths of visible light, so they are able to penetrate the deepest.

Nobuyuki Miyaoka, attending the festival, notes that the local oysters used to be a lot bigger, expressing concern over their current small size and scarcity.

The haul of lobsters, Maine's best known export and a key piece of the state's identity and culture, has declined every year since 2021, and some scientists have cited as a reason warming oceans that spur migration to Canadian waters.

In February 2023, an article in the Mexican press announced the capture of a vessel some 195 nautical miles from the port of Lazaro Cardenas in the state of Michoacan. It had been carrying nearly 700 pounds of cocaine packaged in plastic-wrapped bricks, in addition to 1,650 liters of hydrocarbons in 33 plastic containers. Two Ecuadorian fishermen were among the five detainees, and their immigration records showed unusual activity.

Signs of ageing accelerated when fish were exposed to the chemicals, according to the study, which could have implications for other organisms. Chemical safety regulations tend to focus on short-term exposure to high doses of pesticides and other chemicals, but the study focused on long-term exposure. Low doses of pesticides are widespread in the environment, so their effects should be studied and understood, the authors said.

The animals do, however, have neuronsnerve cells that appear interconnected throughout their body. And now a new study shows that how these animals sleep is surprisingly similar to humans, suggesting that sleep may have evolved before even the most primitive brains. The findings, published on Tuesday in Nature Communications, also help answer one of science's prevailing mysteries: Why do animals sleep?

Recently, while sailing with friends on San Francisco Bay, I enjoyed the sight of harbor porpoises, cormorants, pelicans, seals and sea lions and then the spouting plume and glistening back of a gray whale that gave me pause. Too many have been seen inside the bay recently. California's gray whales have been considered an environmental success story since the passage of the 1972 Marine Mammal Protection Act and 1986's global ban on commercial whaling. They're also a major tourist attraction during their annual 12,000-mile
