If you think working from home is hard, consider the spider, who lives at work in a house it built. Arachnids use their intricate webs to trap meals, navigating across the structure using the vibrations it senses through the hairs on its legs.

Today, a team of researchers at MIT report that they've translated those vibrations into musical tones. What's more, they raise the prospect of someday communicating with spiders, using their vibrational world as a medium for language.

The team presented their research today during the spring meeting of the American Chemical Society. To figure out the sounds of a spider web, they hosted a spider in their lab and laser-scanned the web it constructed in two-dimensional cross-sections.

"Spiders live in this vibrational universe... they live in this world of vibrations and frequencies, which we can now access," said paper co-author Markus Buehler, a materials scientist at MIT, in a phone call. "One of the things we can do with this instrument with this approach is we can, for the first time, begin to feel a little bit like a spider or experience the world like the spider does."

Locals have been left shocked after three whales were washed up on one of the country's most scenic beaches.

Tra Mór in Dunfanaghy, Co Donegal was named in the top ten Irish beaches by the Lonely Planet guide this week.

However, walkers were left stunned at the weekend when they came across the whales washed up on the beach.

The three large carcasses are believed to be that of two adult and one juvenile Cuvier's beaked whales The three whales measure around 6ft, 10ft and 10ft, and two of them have scarring around their bodies.

Entomologist Eric Day says the insects could create a "substantial noise issue" in some communities.

In April 2004, "Mean Girls" was playing in theaters and "Yeah!" by Usher was topping the Billboard music charts.

At the same time, around the mid-Atlantic region, small holes in the ground were opening up from which billions of bulky, red-eyed, winged insects would emerge, readying for a bacchanal of singing and mating -- and reminding humans of a horror movie.

The carcass of a whale shark found washed up on Terrace Beach by regular holiday visitors.
The remains of what appears to be a juvenile whale shark have washed up on Terrace Beach near Eden on Tuesday April 6.

Whale sharks are the largest fish species in the world and can grow to 10-15 metres, but Matt Azzopardi and his family who reported it to Fisheries and National Parks measured it to around four metres.

"It was an incredible experience - we thought it was still alive coz it was rolling in the surf," Matt said.

"It was quite surreal to see it, I paced it out myself to a conservative three and a half metres to over four metres."

Fisheries have since measured it to almost exactly five metres.

Matt made the find with his partner Allison Falzon and their two sons Mason and Jakim, sharing video to their Facebook page Shotgun Odyssey - Travel Oz.

DEAD
Two dead whales, one of which is 16-meters long, washed up on Bangladesh's shore over two days, officials said Saturday, raising suggestions that they were killed by sea pollution.

Officials said the second, much longer whale washed up on Himchhari Beach, outside the resort city of Cox's Bazar, at around 8:30 a.m. (2:30 a.m. GMT) Saturday, just a day after the carcass of another Bryde's whale was found 2 kilometers (1.25 miles) from the spot.

"The carcass of the whale found today is at least 50 feet (16 meters) long and 10 feet wide. It weighs 3 to 4 tonnes," Jahirul Islam, executive director of the Cox's Bazar-based Marine Life Alliance, told AFP.

Islam said the whales could have been killed in a collision with a ship plying the Bay of Bengal, or have died after eating plastics that litter the sea.

The fourth whale washed ashore at Muir Beach in Marin County, the center said Thursday.

Scientists from the mammal center were unable to determine a cause of death for the whale found at Crissy Field. They are still investigating the deaths of the other three whales.

Three gray whales have been found dead in and around the San Francisco Bay in the past week. It's raising concern among marine scientists who said that number is alarming.

It's the start of the whales' northern migration. The center expects one or two whales to wash ashore in a couple weeks but three within a week is a lot. It's reminiscent of 2019 when there was a high number of whale deaths in the Bay.

In scenic San Francisco Bay lies a sad discovery Wednesday, the carcass of a 33-foot male gray whale.

"These creatures, they are such magnificent creatures and to see them dead like this is really heartbreaking," said Sea Valor CEO/Founder Eric Jones.

Images have emerged online showing the coast of the Russian Sakhalin Island in the Pacific Ocean covered with fish. With ecologists saying they're safe to eat, excited fishermen hurried to the seafront for the easiest catch.

Videos of Pacific herring covering Sakhalin's south-western coastline were posted online on Sunday. What looks like thousands of fish, both moving and still, can be seen ashore, with excited men walking among them.

Local ecologist Dmitry Lisitsyn, who posted some of the videos, said that, far from being an ecological disaster, this is a positive sign. The fish, also known as California herring, are on their spawning run, and there are so many that some of them are being washed ashore. The phenomenon shows that the herring population is not endangered, according to the expert.
