We’ve heard of following the yellow brick road, and even following the white rabbit, but scientists have just made a landmark discovery by following a trail of ghostly crabs. For some 20 years, experts believed there was a hydrothermal vent field off the western Galápagos Islands, but they hadn’t been able to pinpoint its exact location. However, while exploring the area they spotted a galatheid crab (also called a squat lobster), and then another, and then another. They traced the crustaceans excitedly as their number grew until, finally, they were led to the elusive hydrothermal goldmine. There are only around 550 known hydrothermal vents in the world, only half of which have actually been seen. The rest have been identified via chemical and temperature signatures in the surrounding water, as Live Science notes. Hydrothermal vents are formed when water seeps into the rock of the seafloor at either a plate margin or where magma is rising to the surface in another part of the plate. The magma heats the water, which causes it to rise, before it’s expelled through fissures in the rock, often forming what are known as chimneys. The new Galápagos field, discovered thanks to the crabs which aggregate around deep-sear vents, extends more than 98,800 square feet (9,178 square metres), and consists of five geyser-like chimneys and three hot springs. The highest temperature so far recorded there is a staggering 288C (550F). As well as the the geysers, hot springs and crabs, the team, from the Schmidt Ocean Institute, found a thriving ecosystem of incredibly adapted organisms. "There were giant tube worms, which can be a couple (of) metres long. There were very large clams, sometimes called dinner plate clams, as well as mussels," said Roxanne Beinart, a biological oceanographer who co-led the expedition. To locate the hydrothermal field, the researchers first began searching the general region where a chemical anomaly had been identified in 2008. "One of the anomalies that we look for is a lens of low oxygen water," expedition co-leader Jill McDermott, a chemical oceanographer at Lehigh University in Pennsylvania, told Live Science. "Oxygen is completely removed through circulation in the seafloor. So the water that's expressed at the seafloor is devoid of oxygen." The team then followed this plume of oxygen-poor water until it disappeared — implying they were close to the vent. They then launched a remotely operated vehicle to inspect the seafloor and traced the breadcrumb trail of crabs to the vent field itself. “With 75 per cent of the seafloor still to map, finding this new vent field shows how much we still have to learn about our planet and those who live on it,” the Schmidt Ocean Institute’s Executive Director Dr Jyotika Virmani said in a statement. “I am continually amazed by the otherworldly beauty of our seafloor and look forward to uncovering more.” And what did the team christen the new hydrothermal vent field? Why, the “Sendero del Cangrejo,” or “Trail of the Crabs,” of course. Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Three quarters of the Irish data watchdog’s GDPR decisions were overruled by European regulators, a report has found. The report indicates that 75% of the Data Protection Commission’s decisions in EU cases over a five-year period were overruled by the European Data Protection Board (EDPB). The EDPB had demanded tougher enforcement action in these cases, the report by the Irish Council for Civil Liberties (ICCL) said, with only one other country in one other case overruled in such a manner. The figures include final decisions from January 2023 that are not yet included in the EDPB register of final decisions, from which the figures are based. If these three cases are not included, the figure is 88% of DPC decisions overruled. The report said that the DPC tends to use its discretion under Irish law to choose “amicable resolution” to conclude 83% of the cross-border complaints it receives, instead of using enforcement measures. The ICCL report claims that Ireland remains “the bottleneck of enforcement” for major cross-border cases in Europe. “When it does eventually do so, other European enforcers then routinely vote by majority to force it to take tougher enforcement action,” it said. As Google, Meta, Apple, TikTok and Microsoft have headquarters in Ireland, the Data Protection Commission is the lead authority investigating data privacy complaints about tech giants in Europe. Some 87% of cross-border GDPR complaints to Ireland’s DPC also involve the same eight companies: Meta, Google, Airbnb, Yahoo!, Twitter, Microsoft, Apple, and Tinder. On EU-wide cases, the ICCL report found that since May 2018 – when GDPR laws came into effect – and late 2022, 64% of the 159 enforcement measures were reprimands, stating that enforcement against tech giants in Europe “remains largely paralysed”. The EDPB register of EU-level decisions shows there were 49 compliance orders issued over four and a half year years. The report called on the European Commissioner for Justice Didier Reynders to “take serious action” to enforce GDPR laws across Europe. Last summer, the Irish Government announced that two additional data protection commissioners would be hired, and that Helen Dixon would be promoted to chairwoman of the DPC – in an attempt to better resource the watchdog in recognition of its growing workload. The DPC has been carrying out a review of its governance structures, staffing arrangements and processes since last summer.

Instagram posts are appearing elsewhere – without the knowledge of the people posting them, and with no way for them to stop it once they do find out. Users of the company’s new Instagram Threads app are finding that their posts are being automatically pushed into their Facebook feeds. The company said that it was “listening” to complaints from users who did not want their posts appearing on Facebook. But it does not appear to be offering a way for people to stop it happening. Meta has often used its various platforms to promote other ones. New apps and features have often been shown in the Facebook news feed especially, as the company looks to introduce them to other users. Facebook has long shown posts from Instagram Reels, for instance. And companies on WhatsApp can buy ads that show on Facebook. The new behaviour means that people loading up their Facebook news feed may see posts that their friends have put on Instagram Threads. Users complained that the behaviour was unwanted, however. “How do I keep my Threads from showing up on Facebook? I want [them] separate and I don’t want my Threads randomly showing up on Facebook in someone’s “for you” or any place else,” one user wrote in response to the company. In response, it confirmed that it had made the change but did not appear to suggest it would be changed. The update was intended “to make it easier for people to see the latest content from Threads directly on Facebook and Instagram”, it said, but it is “listening to feedback like yours as we continue to build on this”. Author and YouTuber Hank Green was one of many who pleaded with the company to go back to keeping posts on the various apps separate. “It’s really true that threads and Facebook have very different cultures and I choose specifically what I want to go where. For other people, that can actually be a little unsafe. Let people opt out. Next time, build that first. Move slow, fix things. We’re doing good here,” he wrote in response to the official Threads account.
