California’s rampant sea urchin problem
https://www.theguardian.com/us-news/...ni-kelp-forest

But these vibrant little aliens – purple sea urchins, in actuality – have become a major headache for the Pacific west coast. Their population has exploded by 10,000% since 2014, with scientists blaming the decline of sea otter and starfish populations – two of the urchin’s natural predators.

Hundreds of millions of purple sea urchins now blanket the coast from Baja to Alaska, where they have been devouring the region’s vital kelp forests, doing untold damage to the marine ecosystem in the process.

In California, it is estimated that 95% of the kelp forests, which serve as both shelter and food to a wide range of marine life, has been decimated and replaced by so-called “urchin barrens” – vast carpets of spiked purple orbs along the ocean floor.

It shouldn’t have been a hard sell. Sea urchin, or uni in the sushi world, is considered a delicacy in the fine dining circles. “The two main descriptors I would use are sweet and briny, similar to an oyster, similar to a clam,” said culinary scientist Ali Bouzari. “They taste like the sea because they live in the sea. They’re sweet, umami and a little bit salty. The texture is very creamy. It’s very similar to room-temperature butter.”

During the pandemic, however, fine dining has been harder to come by. And the retail costs, which range from $9 to $12 per urchin at your local fishmonger, isn’t something every home cook can justify.

Sea urchins are essentially a ball of hard purple spikes containing five egg sacs, which is what we eat – in the culinary world, they’re described as the tongues, the roe, the uni.

They have no eyes or brain, but they do have mouths, which they use to suck up everything in their way, kelp or otherwise. Bouzari calls them the “Roombas of the ocean”.

Philippines: Studying bats might help prevent another pandemic

After dark in the Philippine province of Laguna, scientists use big nets to catch bats. They study the animals in an effort to prevent the next pandemic.


Casting their nets

The researchers, who call themselves "virus hunters," are out to catch thousands of bats for a simulation model. They hope that this will help them prevent another pandemic on the scale of the COVID-19 crisis in the future.








Untangling bats

In the dense rainforest, it can take hours for the "virus hunters" to find what they are looking for. Once they have detected the bats, they carefully place them in cloth bags so they can be examined and measured.






Swabbed for science

The researchers log all the details for further analysis, including saliva and fecal samples. Then, the animals are returned to the wild.







Avoid the next pandemic

"What we’re trying to look into are other strains of coronavirus that have the potential to jump to humans," according to Phillip Alviola, the ecologist who heads the science team that has studied bat viruses for more than a decade.









Isolate the viruses

"If we know the virus itself and we know where it came from, we know how to isolate that virus geographically," Phillip Alviola said.








More data needed

Researchers from the University of the Philippines in Los Banos, located about 60 kilometers (37 miles) southeast of the capital, Manila, plan on continuing the Japan-funded project over the next three years. They hope that more information about bats will give them more insight into coronaviruses, also with regard to climate, temperature and how they transmit to humans.









Bat-borne viruses

"What we’re after is finding out if there are any more viruses from bats that can be transmitted to humans," Phillip Alviola said. Bat-borne viruses include pathogens like those that cause severe acute respiratory syndrome (SARS) and Middle Eastern respiratory syndrome (MERS). The World Health Organization (WHO) suspects that bats may have been the first hosts of Sars-CoV-2.

shoppers in Australia find venomous snake in Aldi fresh produce bag
https://www.theguardian.com/australi...-fresh-produce

A Sydney couple received a fright when they discovered a rare venomous snake in a bag of supermarket lettuce – but recovered and later used the fresh produce in a salad wrap.

The juvenile pale-headed snake, Hoplocephalus bitorquatus, was tucked into a two-pack of cos lettuce which Alexander White and his partner, Amelie Neate, purchased from an Aldi supermarket in Sydney on Monday.

“It was moving around and flicking its little tongue out,” White said. “It was actually its tongue which let me know it wasn’t a giant worm. I would have been more comfortable with a worm, to be honest.”

The reptile was about 20cm long and appeared to have been sleeping peacefully in the lettuce in the supermarket’s refrigerated grocery cabinet until White picked it up, carried it around the store, then jostled it in his backpack for the 10-minute bicycle ride home.

The snake emerged as they were unpacking their groceries at home. They called wildlife rescue organisation Wires and were advised the snake was possibly a baby eastern brown – one of the most venomous and aggressive species in Australia.

But after an extensive amount of snake photography, it was identified as a pale-headed snake, a species that a snake expert told the couple was “medically significant”.

“I thought that meant it had medicinal properties,” said White. “Apparently it means that if you are bitten you have to go to hospital pretty quickly.” They bite repeatedly when provoked, said Neate.

According to the Australian Museum, pale-headed snakes are a “shy but nervous species, easily agitated if cornered”. There have been no recorded fatalities, but the museum states “an envenomation can produce some unpleasant symptoms, including severe headache, blurred vision, localised pain, and abnormal bleeding”.

White said the juvenile snake was quite cute. He and Neate spent some time videoing it and conducting video calls between the snake and their children, who were away for school holidays, while awaiting expert assistance.

The snake and lettuce were moved to a Tupperware container “but we were opening the lid a bit because we were worried about it running out of air”.

A snake handler from Wires arrived at 10.30pm to retrieve the animal, which was transferred to a heated container. With the help of Aldi, they traced the origin of the lettuce back to Toowoomba, and are attempting to organise transport home for the snake.

Wires left the lettuce behind and White ate it for lunch.

“We’ve worked with the customer and the team at Wires to identify the snake’s natural habitat, which is certainly not an Aldi store,” a spokesperson said. “We thank Wires for their support on this.”

Aldi said it was working with the produce supplier to “investigate how this incident could have possibly occurred”.
