New 'chiral vortex' of light allows chemists to 'see' molecules through the mirror

An entirely new structure of light is helping to measure chirality in molecules more accurately and robustly than ever before, in a major potential step for the pharmaceutical industry. Published in Nature Photonics, a team from King's College London and the Max Born Institute have created an entirely new structure of light that traces out a chiral curve over time. This chiral curve has different shapes at different points in space, forming a vortex structure. By interacting with chiral particles it moves through over time, the new "chiral vortex" provides an accurate and robust form of measurement.

(Sorry to be that guy but) the leaf sheep is not actually a nudibranch, but instead part of the closely related order sacoglossa. Nudibranches are carnivorous while sacoglossa are herbivorous and feed by sucking the sap out of microscopic algae. Many sacoglossa perform a process called kleptoplasty, where they reuse chloroplasts from the algal sap they feed on and implement them into their cells. Some notable examples are the bivalve snails in the family juliidae, the eastern emerald elysia (elysia chlorotica) and obviously the sea sheep. Another slug from the order elysia (elysia rufescens) reuses defensive molecules called kahalalides as well as chloroplasts. Most sacoglossans survive primarily through heterotrophic means (ingesting and digesting) and photosynthesise when food is scarce or unavailable as a last resort. Though research has shown leaf sheep can survive long periods of time with little to no food of heterotrophic or homotrophic (photosynthetic) origin. They store their chloroplasts in cerata, which are structures often found on nudibranches and regularly used for gas exchange or- in blue glaucus’ case- for attack and defence. They also have rhinophores protruding from their face, structures also commonly found on nudibranches, which are chemosensory organs (essentially face tongues) that appear ear like on nudibranches and sacoglossans alike.

To conclude: while leaf sheep are very similar to nudibranches, they belong to the sacoglossan family (which is good because sacoglossans are just as cool) and luckily are not the only animals to photosynthesise.

(I’m researching them for a highschool project and am so obsessed haha)

So not technically a fish but I absolutely love these lil fellas

They’re Nudibranch sea slugs and they all look so pretty!!!!!

Some notable exception are the Sea Bunny (left) which is just the most adorable thing I’ve ever seen

And the Leaf Sheep (right), which is the only animal known to be capable of photosynthesis!

i am SUCH a nudibranch fan oh my god. actual underwater fae creatures. beloved little freak animals. i want to eat them like cereal

Wake up babe new fish dropped

Conservation good news: Giant anteaters are returning to south Brazil thanks to rewilding efforts

Recent giant anteater sightings in Rio Grande do Sul state indicate the species has returned to southern Brazil, where it had been considere

— Recent giant anteater sightings in Rio Grande do Sul state indicate the species has returned to southern Brazil, where it had been considered extinct for more than a century.

— Experts concluded that the giant anteater ventured across the border from the Iberá Park in northeastern Argentina where a rewilding project has released around 110 individuals back into the habitat.

— The sightings emphasize the importance of rewilding projects, both to restore animal populations in specific regions and help ecosystems farther afield.

— Organizations across Brazil are working to protect and maintain current giant anteater populations, including rallying for safer highways to prevent wildlife-vehicle collisions that cause local extinctions.

Playing back hours of footage from a camera trap set in Espinilho State Park in the south of Brazil in August 2023, Fábio Mazim and his team banked on possible sightings of the maned wolf or the Pantanal deer and had their fingers crossed for a glimpse of a Pampas cat (Leopardus pajeros), one of the most threatened felines in the world.

What they didn’t expect to see was an animal long presumed extinct in the region. To their surprise, the unmistakable long snout and bushy tail of a giant anteater ambled into shot.

"We shouted and cried when we saw it,” the ecologist from the nonprofit Pró-Carnívoros Institute told Mongabay. “It took a few days to grasp the importance of this record. A sighting of a giant anteater was never, ever expected.”

Last seen alive in the southwest of the Rio Grande do Sul state in 1890, the giant anteater (Myrmecophaga tridactyla) has since been spotted 11 times since August 2023, although the scientists are unsure whether it’s the same one or different individuals. However, the sightings confirm one clear fact: The giant anteater is back.

It's a huge win for the environment. Giant anteaters play an important role in their ecosystems, helping to control insect numbers, create watering holes through digging and are prey for big cats such as jaguars and pumas.

The habitat of the giant anteater stretches from Central America toward the south cone of Latin America.

Its conservation status is “vulnerable,” although it is considered extinct in several countries, including El Salvador, Guatemala and Uruguay, as well as specific regions such as the states of Rio de Janeiro, Espirito Santo, Santa Catarina and (until now) Rio Grande do Sul in Brazil and the Cordoba and Entre Rios regions in Argentina.

‍In the last six months, the giant anteater was spotted on camera 11 times in the Espinilho State Park in the state of Rio Grande do Sul in Brazil. It was the first time in 130 years that the species has been seen alive there.

Yet not only is it a triumph for conservationists to see these animals returning to Brazilian biomes, it’s also a surprising mark of success for a rewilding program about 150 kilometers (93 miles) away in neighboring Argentina.

‍Rewilding Argentina’s biomes

‍Iberá National Park in Corrientes province in northeastern Argentina is a 758,000-hectare (1.9 million-acre) expanse of protected land comprising a part of the Iberá wetlands with its swaths of grasslands, marshes, lagoons and forests. The region was once home to just a handful of giant anteaters after habitat loss, hunting and vehicle collisions decimated the population.

Since 2007, the NGO Rewilding Argentina, an offspring of the nonprofit Tompkins Conservation, has been reintroducing the species back to the area, most individuals being orphaned pups rescued from vehicle collisions or poaching.

So far, they have released 110 giant anteaters back into the wild. Nowadays, several generations inhabit the park, transforming it from “a place of massive defaunation to abundance,” Sebastián Di Martino, director of conservation for Rewilding Argentina, was quoted as saying in an official statement.

The project has been so successful that the giant anteaters appear to be venturing farther afield and moving to new territories beyond national borders, such as Espinilho State Park in Brazil’s Rio Grande do Sul region...

Experts now hope that a giant anteater population can reestablish itself naturally in Espinilho State Park without the need for human intervention.

“The giant anteater returning to Rio Grande do Sul shows the success of the work done in Argentina and how it’s viable, possible and important to do rewilding and fauna reintroduction projects,” Mazim said. “It is also an indication that the management of conservation units and also the agricultural areas of the ecosystems are working,” he added. “Because if large mammals are coming from one region and settling in another, it is because there is a support capacity for them. It is an indication of the health of the environment.”
