 — 

Gondolas, canals and all those bridges. For many tourists, Venice is all that and only that: the floating city born for Instagram.

For others it’s a symbol of the excesses of the modern world: a city turned into a theme park, trampled by overtourism and hollowed out by vacation rentals. The statistics are stark. Around 30 million tourists visit Venice every year, dwarfing the local population, which has now dwindled to less than 50,000.

Venetians wanting to remain in their city face a lack of housing stock — since homes have been converted into vacation rentals — a lack of shops for day-to-day life, and a lack of jobs for anyone not involved in the tourist industry.

In the meantime, the visitors keep coming, and keep posting those delectable canal shots on Instagram. Around 90% of them are thought to be day-trippers — so although they don’t take up that ever-dwindling housing stock, they use city resources but leave virtually no money behind in the local economy.

No wonder some people call Venice the “dying city” and the “sinking city,” Simone Venturini, the city councilor for tourism, tells CNN in documentary “The Whole Story: Saving Venice.”

But while the city authorities’ actions — like the 5 euro (roughly $5) daytripper fee trialed in 2024 and set to be repeated in 2025, and the Smart Control Room, which monitors the movements of visitors to the city — have met a mixed response, plenty of other Venetians are taking their own steps to preserve life in the city as they know it.

What’s more, many of them are working with visitors, hoping to allay the damage caused by mass tourism with more sustainable projects.

In 2018, Emanuele Dal Carlo launched Fairbnb — a platform for vacation rentals owned strictly by local residents.

One of the major reasons for the exodus of Venetians to the mainland in recent years is the dearth of housing stock in the city. There are currently 8,322 Airbnb listings in Venice according to Inside Airbnb, 77% of which are entire properties. Two thirds of hosts have multiple listings –— meaning they’re not just renting out their spare room, or their late nonna’s apartment.

“We have nothing against private property, but if you rent 20 houses only to tourists, then you become a problem for your community,” says Dal Carlo, who is one of the tens of thousands of Venetians who have left the city for the mainland, a 10-minute train ride (plus ferry ride to the city center) away.

Fairbnb is a similar platform — but all its rentals are owned by local residents, and owners are capped on the number of properties they can advertise.

What’s more, 50% of the platform fees are channeled into an on-the-ground project in the destination they are visiting.

Tourists may feel that they’re not doing much harm by renting a regular apartment for a few days, but with a rapidly depleting housing stock for locals, Dal Carlo warns that there’s a tipping point.

“There’s not going to be another Venice,” he says. “Once you have helped change this place forever, it’s not coming back.”

Other residents fight decline by keeping traditions going. Elena Almansi practices voga alla veneta, the stand-up rowing technique used by Venetians to navigate the lagoon for centuries. A competitor in Venice’s regular regattas, she’s one of a group of women offering rowing lessons with Row Venice, a sustainable tourism initiative which takes visitors on trips through the canals of the city, seeing its buildings the way they were meant to be seen: from the water.

Then there’s Matteo Silverio, whose startup, Rehub, takes waste materials from the famous glassblowing process on Murano, and upcyles it, using a 3D printer to turn it into artistic creations, including crockery.

Another person taking up the baton is Michela Bortolozzi, a designer who had lived abroad but returned to her native city during the pandemic. Realizing she wanted to stay and buffer the community, she opened a shop, now called Relight Venice, where she makes products that look like souvenirs but give you pause for thought.

Her signature products are candles and soaps taking the form of the architectural flourishes of the Venetian gothic architecture. She started off by making lollipops using the pattern of the Doge’s Palace’s famous colonnade.

“That was the question: you want to consume it or keep it?” she asks.

“My point is that Venice is as beautiful as my product — much more so. Don’t consume Venice because we cannot rebuild or re-buy it.”

She hopes that other young people will open similar businesses. “If we can fight, we can stay,” she says.

Is it not already too late to save Venice? Not according to Fabio Carrera, whose Venice Project Center at the Worcester Polytechnic Institute in Massachusetts has been studying the city’s problems since 1988. Born in Venice, he splits his time between Italy and the US.

“I think enough people realize that the [tourism] card has been overplayed now and there’s going to be some sort of retrenching,” he says, mentioning the recent protests in destinations like Mallorca and the Canary Islands as examples of local communities pushing back.

“I’m oddly optimistic,” he says.

Carrera’s team studies ways to improve the liveability of the city, from introducing boat routes for deliveries in order to cut down on moto ondoso (the waves produced by boats which slap against and weaken the city foundations) to looking at the potential for a microalgae farm in the lagoon.

The lagoon is of course Venice’s blessing and curse. It was the water that allowed the city to become one of the most formidable maritime powers of the medieval and renaissance periods, and found the Republic of Venice — still to this day the world’s longest-lasting republic.

But new canals cut through the lagoon during the industrial age, increasing maritime traffic and rising water levels due to climate change all mean that the city is flooding easier and more frequently than ever before.

In 2020, Venice saw the debut of the MOSE flood barriers, which had been in the works since 1988. But already the barriers — which were designed to be raised a handful of times each year — are in frequent use, especially during the fall and winter. In its first 14 months, the system was used 33 times.

Not only does this have sweeping cost implications — the barriers cost around 200,000 euros ($206,000) to raise every time — but there are knock-on effects for the lagoon, which is “designed” by nature to flush itself out twice a day. Closing the barriers also means closing off access to the port, which is one of the most important in Italy.

But while scientists are studying how to handle the lagoon, Carrera is looking at more practical issues to combat Venice’s major social problem: the lack of residents. For starters, he thinks a better transport system would help attract people to live in Venice.

“It could make a big difference if we had, say, a subway system which was talked about for a while,” he says. ”You could live in Venice and work on the mainland and get there real quick. On the mainland around Venice, there are plenty of jobs, hi tech jobs — all the stuff we’re talking about bring here already, is there.”

Dal Carlo agrees that attracting people who have nothing to do with tourism to live in Venice is key. “I think it’s important that we are trying to attract people, or to maintain here people that are clever, entrepreneurial because that is in the genes of the city,” he says, adding that Venice was never “a city of shop owners and renters. That’s what it’s become.”

Bortolozzi believes that responsible tourism can help. “I think it is important that if people from abroad meet a local person to get to know the culture, get to know the tradition, get to know our problem and our happiness… he can maybe enjoy Venice in a nice way and maybe help us to preserve it,” she says.

Cesare Perris, who owns Squero San Isepo, one of the last boatyards in the city, fears it might be too late to help Venice — but adds that, if it isn’t, it could be huge. He quotes a friend, who likes to say that saving Venice is the same as saving the world from mass tourism:

“If you find a way to have tourists in Venice that don’t kill the city, we maybe find the method to save all the cities of the world.”

Incredible images showcase scientists at work

Published

CNN
 — 

A biologist tracking whales in the Norwegian fjords, a vast telescope pictured below breathtaking skies and a scientist holding tiny froglets all feature in the top images from this year’s Nature Scientist at Work competition.

Six winners were selected from the more than 200 entries submitted to the competition, which showcases the diverse, fascinating and challenging work that scientists carry out all over the world. Now in its sixth year, the contest is judged by a jury made up of staff from the journal Nature, which runs the competition.

The overall winning image was taken by Emma Vogel, a PhD student at the University of Tromsø. It features biologist Audun Rikardsen scanning the water around fishing trawlers in northern Norway for whales while holding an airgun, which he uses to deploy tags that track the marine animals.

“You could smell their breath,” Vogel said of the whales in a competition press release Tuesday. “And you could hear them before you can see them, which is always quite incredible.”

The winning images show scientists in cold and warmer climates. One features researchers boring an ice core in the archipelago of Svalbard, while another shows a biologist holding tiny froglets in California’s Lassen National Forest.

A scientist is pictured next to a weather balloon in the fog on Mount Helmos in Greece in a separate image, while another shows the vast South Pole Telescope at the Amundsen–Scott South Pole station lit by an aurora overhead.

The final winning picture shows the silhouette of a man entering a cabin against the dark backdrop of a starlit sky in eastern Siberia. His colleague, photographer Jiayi Wang, said that, while the remote location where they worked can be beautiful, long periods of time spent there can also be tedious. “There’s no network there. And the only thing you can do is watch the rocks,” he said in the press release.

47 million-year-old bug is the oldest singing cicada fossil from Europe

Pressed into a piece of rock is the flattened, 47 million-year-old body of a cicada. Measuring about 1 inch (26.5 millimeters) long with a wingspan of 2.7 inches (68.2 millimeters), its fossilized form is nearly intact, with its veined wings spread wide.

Scientists recently described the insect as a new genus and species, using this fossil and one other that was nearly as well preserved, from the same site. Even though the specimens are female, their location on the cicada family tree suggests that males of this species could sing as modern cicadas do. Found in Germany decades ago, their presence there reveals that singing cicadas dispersed in Europe millions of years earlier than once thought.

The fossils are also the oldest examples of “true” singing cicadas in the family Cicadidae, researchers reported April 29 in the journal Scientific Reports. Most modern cicadas belong to this family, including annual cicadas that appear every summer worldwide, as well as broods of black-bodied and red-eyed periodical cicadas, which emerge from May to June in eastern North America in cycles of 13 or 17 years. Brood XIV, one of the biggest broods, emerges across a dozen US states this year. Cicadas are found on every continent except Antarctica, and there are more than 3,000 species.

The fossil record for insects in general is abundant in just a few dozen locations, and while modern cicada species are numerous today, paleontologists have documented only 44 Cicadidae fossils. The earliest definitive fossil of a singing cicada was discovered in Montana and dates from 59 million to 56 million years ago, said lead study author Dr. Hui Jiang, a paleontologist and researcher with the Bonn Institute of Organismic Biology at the University of Bonn in Germany. Its newly described relative is the earliest singing cicada from Europe, Jiang told CNN in an email.

Because the body structures of the European fossils were so well preserved, scientists were able to assign the ancient insect to a modern tribe of cicadas called Platypleurini, “which is today primarily distributed in tropical and subtropical regions of sub-Saharan Africa and Asia, but is absent from Europe,” Jiang said.

Prior research suggested that this lineage evolved in Africa about 30 million to 25 million years ago and dispersed from there, according to Jiang. “This fossil pushes back the known fossil record of sound-producing cicadas in the tribe Platypleurini by approximately 20 million years, indicating that the diversification of this group occurred much earlier than previously recognized,” the researcher added.

The discovery hints that this group of cicadas evolved more slowly than prior estimates from molecular data proposed, said Dr. Conrad Labandeira, a senior research geologist and curator of fossil arthropods at the Smithsonian Museum of Natural History in Washington, DC.

“This suggests that older fossils of the Platypleurini are yet to be discovered,” said Labandeira, who was not involved in the research. “Such discoveries would assist in providing better calibrations for determining a more realistic evolutionary rate.”

This reconstruction shows the newly described cicada species Eoplatypleura messelensis.

Researchers named the cicada Eoplatypleura messelensis. Its name refers to where the specimens were discovered: the Messel Pit in Germany, a rich fossil site dating to the Eocene epoch (57 million to 36 million years ago). Excavated in the 1980s, the fossils have since been in the collection of the Senckenberg Research Institute and Natural History Museum Frankfurt in Germany, said senior study author Dr. Sonja Wedmann, head of Senckenberg’s paleoentomology department.

A very deep volcanic lake, with a bottom where no oxygen penetrated, once filled the Messel Pit. That environment created ideal conditions for fossilization, and fine-grain sediments from this former lake bed hold a variety of Eocene life, Wedmann told CNN in an email.

“The excellent preservation not only of insects, but of all groups of organisms, is the reason why Messel is an UNESCO world heritage site,” a designation it earned in 1995, Wedmann said.

The more complete of the two cicada fossils “is one of the best preserved insects from the Messel pit fossil site,” Wedmann added. “Senckenberg has a collection of over 20,000 fossil insects from Messel, and among these it stands out because of its really beautiful and complete preservation.”

In its overall head and body shape, E. messelensis strongly resembles modern cicadas. Its rostrum — a snoutlike mouth — is intact, but closer analysis is needed to tell whether it used the rostrum for feeding on plant tissues called xylem, as most modern cicadas do, Labandeira said.

E. messelensis also shows hints of colors and patterns in its wings. This feature camouflages modern cicadas as they cling to tree trunks, and it may have served a similar purpose for E. messelensis, according to Jiang.

However, E. messelensis differs from modern cicadas in subtle ways. For example, its forewings are broader and less elongated than those of species alive today, which may have affected how it flew.

Would the ancient cicada’s call have sounded like those of its modern relatives? “We can’t know the exact song,” Jiang said. However, based on the cicada’s body shape and placement in the singing cicada group, “it likely produced sounds similar in function to modern cicadas.”

When Brood XIV emerges in the billions in the late spring and early summer of 2025, their calls will measure from 90 to 100 decibels — as loud as a subway train. Other types of cicadas produce an even bigger ruckus: Songs of the African cicada Brevisana brevis peak at nearly 107 decibels, about as loud as a jet taking off.

The volume of the ancient species’ songs may have been even louder than that, Jiang said. The abdomen of E. messelensis is broader and larger than those of its modern relatives, suggesting that males could have had a larger resonating cavity. This cavity may have amplified sound from the vibrating structures in their abdomens, called tymbals, to produce a louder buzz.

“Of course, this is only a hypothesis,” Jiang added. “Future studies on how morphology relates to sound production in modern cicadas will help to test it.”

Keir Starmer: UK police arrest man after fire at UK PM’s house

Published

CNN
 — 

British police said on Tuesday they had arrested a 21-year-old man on suspicion of arson after counter-terrorism officers launched an investigation into three fires, including one at Prime Minister Keir Starmer’s private home.

Police were called to reports of a fire in the early hours of Monday morning at the property in Kentish Town in north London, the area that Starmer represents in parliament.

Nobody was injured but damage was caused to the property’s entrance, police said.

The man was arrested in the early hours of Tuesday on suspicion of arson with intent to endanger life in connection with the fire and two further incidents, police said. He remains in custody, they added.

Police are investigating whether a fire at the entrance of a property in nearby Islington on Sunday and a vehicle fire in Kentish Town on Thursday are linked to the incident on Monday.

A BBC report said the Islington property was also connected to the prime minister.

Starmer lived in the terraced house on a back street with his wife and two children before he moved into Number 10 Downing Street when he became prime minister last July.

Officers from London’s Metropolitan Police Counter Terrorism Command were leading the investigation due to the property’s connections with a high-profile public figure, police said.

His spokesperson thanked the emergency services for their work on Monday.
