first_imgGo back to the enewsletterShipbuilder Fincantieri has announced that Virgin Voyages has signed a contract valued at approximately 700 million euros for the construction of a fourth cruise ship, to be delivered at the end of 2023.The new vessel will be a sister ship of the three ships on order with Fincantieri. Construction is underway at the Sestri Ponente shipyard (Genoa) and the first three ships will enter Virgin Voyage’s fleet in 2020, 2021 and 2022 respectively.The fourth vessel will be approximately 110,000 gross tons, 278 metres long and 38 meters wide. It will feature over 1,400 guest cabins designed to host more than 2,770 passengers, accompanied by 1,100 crew members on board to deliver the famed Virgin service.Construction of Virgin Voyages’ first ship, Scarlet Lady, is already full steam ahead. The announcement of the fourth vessel comes almost 12 months to the day from when Virgin Voyages hosted a “ship tease” to reveal details of the cruise line, and some six months after renderings were released to whet the appetite of future cruisers. Last month Virgin Voyages revealed it would be introducing the first tattoo parlour at sea, called Squid Ink.Meanwhile, Virgin Group founder Sir Richard Branson has revealed that Cuba will be one of the first destinations in the Caribbean that Scarlet Lady will visit, saying it happens to be “one of my favourites in the world”.“Get ready sailors for sun, salsa dancing and incredible city sights, the Scarlet Lady is heading to… Havana, Cuba!” Branson revealed.Go back to the enewsletterlast_img read more

Without lots of genetic material to reshuffle, future generations are less able to adapt to changing environmental conditions. Now, a new genetic analysis of narwhals is turning that notion on its head: Despite low genetic diversity, these “unicorns” of the ocean seem to be doing just fine.Narwhals, medium-size whales that live in the Arctic, are known for some genetic quirks. After multiple studies uncovered low genetic diversity in several narwhal genes, a team of researchers decided to analyze the whale’s entire genome. Using DNA from the frozen liver tissue of a narwhal found near Greenland, they calculated the genetic variation of the species and estimated the population size of narwhals into the deep past.Their results reveal a profound lack of diversity across the narwhal’s genome, they report today in iScience. Compared with 14 other mammal species, narwhals were far less genetically diverse. For example, bowhead whales have twice as much variation, while pandas’ genomes are more than three times as diverse. What’s more, the team found no evidence of an inbreeding or die-off “bottleneck.” Instead, narwhal populations appear to have declined slowly starting 2 million years ago and have maintained a low genetic diversity for the past million years. Such slowly shrinking diversity has been seen in mountain gorillas and Channel Island foxes, but this time, the common culprits of inbreeding and isolation don’t appear to be to blame. The narwhal’s abundance—there are more than 170,000 living in the wild—may come from a population explosion driven by favorable environmental conditions 115,000 years ago. Since then, genetic diversity may simply have not had enough to time to catch up. But the researchers note that the narwhal isn’t totally out of the woods; with a range restricted to the rapidly warming Arctic, it’s unclear whether the narwhal’s uniform genome will be able to cope with ongoing climate change.
