Three former executives at the French video game company Ubisoft used their position to bully or sexually harass staff, leaving women terrified and feeling like pieces of meat, a French court has heard.The state prosecutor Antoine Haushalter said the trial of three senior game creators for alleged bullying, sexual harassment and, in one case, attempted sexual assault was a “turning point” for the gaming world. It is the first big trial to result from the #MeToo movement in the video games industry, and Haushalter said the case had revealed “overwhelming” evidence of harassment.In four days of hearings, female former staff members variously described being tied to a chair, forced to do handstands, subjected to constant comments about sex and their bodies, having to endure sexist and homophobic jokes, drawings of penises being stuck to computers, a manager who farted in workers’ faces or scribbled on women with marker pens, gave unsolicited shoulder massages, played pornographic films in an open-plan office, and another executive who cracked a whip near people’s heads. The three men deny all charges.Haushalter said “the world of video games and its subculture” had an element of “systemic” sexism and potential abuse. He said the #MeToo movement in the gaming industry had allowed people to speak out.“It’s not that these actions were not punished by the law before. It’s just that they were silenced, and from now on they will not be silenced,” he said.Ubisoft is a French family business that rose to become one of the biggest video game creators in the world. It has been behind several blockbusters including Assassin’s Creed, Far Cry and the children’s favourite Just Dance.The court in Bobigny, in Seine-Saint-Denis, heard that between 2010 and 2020 at Ubisoft’s offices in Montreuil, east of Paris, the three executives created an atmosphere of bullying and sexism that one member of staff likened to a “boys’ club”. One alleged victim told the court: “The sexual remarks and sexual jokes were almost daily.”Tommy François, 52, a former vice-president of editorial and creative services, is accused of sexual harassment, bullying and attempted sexual assault. He was alleged once to have tied a female member of staff to a chair with tape, pushed the chair into a lift and pressed a button at random. He was also accused of forcing one woman wearing a skirt to do handstands.“He was my superior and I was afraid of him. He made me do handstands. I did it to get it over with and get rid of him,” one woman told the court.At a 2015 office Christmas party with a Back to the Future theme, François allegedly told a member of staff that he liked her 1950s dress. He then allegedly stepped towards her to kiss her on the mouth as his colleagues restrained her by the arms and back. She shouted and broke free. François denied all allegations.Another witness told the court that during a video games fair in the US, François “grabbed me by the hair and kissed me by force”. She said no one reacted, and that when she reported it to her human resources manager she was told “don’t make a big thing of it”.The woman said that later, in a key meeting, another unnamed senior figure told staff he had seen her “snogging” François, “even though he knew it had been an assault”.She said François called her into his office to show her pictures of his naked backside on his computers and on a phone. “Once he drew a penis on my arm when I was in a video call with top management,” she said.The woman said these incidents made her feel “stupefied, humiliated and professionally discredited”.François told the court he denied all charges. He said there had been a “culture of joking around”. He said: “I never tried to harm anyone.”Serge Hascoët told the court: ‘I have never wanted to harass anyone and I don’t think I have.’ Photograph: Xavier Galiana/AFP/Getty ImagesSerge Hascoët, 59, Ubisoft’s former chief creative officer and second-in-command, was accused of bullying and sexual harassment. The court heard how at a meeting of staff on an away day he complained about a senior female employee, saying she clearly did not have enough sex and that he would “show how to calm her” by having sex with her in a meeting room in front of everyone.He was alleged to have handed a young female member of staff a tissue in which he had blown his nose, saying: “You can resell it, it’s worth gold at Ubisoft.”The court heard he made guttural noises in the office and talked about sex. Hascoët was also alleged to have bullied assistants by making them carry out personal tasks for him such as going to his home to wait for parcel deliveries.Hascoët denied all the charges. He said: “I have never wanted to harass anyone and I don’t think I have.”The former game director Guillaume Patrux, 41, is accused of sexual harassment and bullying. He was alleged to have punched walls, mimed hitting staff, cracked a whip near colleagues’ faces, threatened to carry out an office shooting and played with a cigarette lighter near workers’ faces, setting alight a man’s beard. He denied the charges.The panel of judges retired to consider their verdict, which will be handed down at a later date.

Extra-sensory perception The nine-armed octopus and the oddities of the cephalopod nervous system A mix of autonomous and top-down control manage the octopus's limbs.

Their abilities to recognize faces, solve puzzles, and learn behaviors from other octopuses make these animals a captivating study. To perform these processes and others, like crawling or exploring, octopuses rely on their complex nervous system, one that has become a focus for neuroscientists. With about 500 million neurons—around the same number as dogs—octopuses’ nervous systems are the most complex of any invertebrate. But, unlike vertebrate organisms, the octopus’s nervous system is also decentralized, with around 350 million neurons, or 66 percent of it, located in its eight arms. “This means each arm is capable of independently processing sensory input, initiating movement, and even executing complex behaviors—without direct instructions from the brain,” explains Galit Pelled, a professor of Mechanical Engineering, Radiology, and Neuroscience at Michigan State University who studies octopus neuroscience. “In essence, the arms have their own ‘mini-brains.’” A decentralized nervous system is one factor that helps octopuses adapt to changes, such as injury or predation, as seen in the case of an Octopus vulgaris, or common octopus, that was observed with nine arms by researchers at the ECOBAR lab at the Institute of Marine Research in Spain between 2021 and 2022. By studying outliers like this cephalopod, researchers can gain insight into how the animal’s detailed scaffolding of nerves changes and regrows over time, uncovering more about how octopuses have evolved over millennia in our oceans. Brains, brains, and more brains Because each arm of an octopus contains its own bundle of neurons, the limbs can operate semi-independently from the central brain, enabling faster responses since signals don’t always need to travel back and forth between the brain and the arms. In fact, Pelled and her team recently discovered that “neural signals recorded in the octopus arm can predict movement type within 100 milliseconds of stimulation, without central brain involvement.” She notes that “that level of localized autonomy is unprecedented in vertebrate systems.” Though each limb moves on its own, the movements of the octopus’s body are smooth and conducted with a coordinated elegance that allows the animal to exhibit some of the broadest range of behaviors, adapting on the fly to changes in its surroundings. “That means the octopus can react quickly to its environment, especially when exploring, hunting, or defending itself,” Pelled says. “For example, one arm can grab food while another is feeling around a rock, without needing permission from the brain. This setup also makes the octopus more resilient. If one arm is injured, the others still work just fine. And because so much decision-making happens at the arms, the central brain is freed up to focus on the bigger picture—like navigating or learning new tasks.” As if each limb weren’t already buzzing with neural activity, things get even more intricate when researchers zoom in further—to the nerves within each individual sucker, a ring of muscular tissue, which octopuses use to sense and taste their surroundings. “There is a sucker ganglion, or nerve center, located in the stalk of every sucker. For some species of octopuses, that’s over a thousand ganglia,” says Cassady Olson, a graduate student at the University of Chicago who works with Cliff Ragsdale, a leading expert in octopus neuroscience. Given that each sucker has its own nerve centers—connected by a long axial nerve cord running down the limb—and each arm has hundreds of suckers, things get complicated very quickly, as researchers have historically struggled to study this peripheral nervous system, as it’s called, within the octopus’s body. “The large size of the brain makes it both really exciting to study and really challenging,” says Z. Yan Wang, an assistant professor of biology and psychology at the University of Washington. “Many of the tools available for neuroscience have to be adjusted or customized specifically for octopuses and other cephalopods because of their unique body plans.” While each limb acts independently, signals are transmitted back to the octopus’s central nervous system. The octopus’ brain sits between its eyes at the front of its mantle, or head, couched between its two optic lobes, large bean-shaped neural organs that help octopuses see the world around them. These optic lobes are just two of the over 30 lobes experts study within the animal’s centralized brain, as each lobe helps the octopus process its environment. This elaborate neural architecture is critical given the octopus’s dual role in the ecosystem as both predator and prey. Without natural defenses like a hard shell, octopuses have evolved a highly adaptable nervous system that allows them to rapidly process information and adjust as needed, helping their chances of survival. Some similarities remain While the octopus’s decentralized nervous system makes it a unique evolutionary example, it does have some structures similar to or analogous to the human nervous system. “The octopus has a central brain mass located between its eyes, and an axial nerve cord running down each arm (similar to a spinal cord),” says Wang. “The octopus has many sensory systems that we are familiar with, such as vision, touch (somatosensation), chemosensation, and gravity sensing.” Neuroscientists have homed in on these similarities to understand how these structures may have evolved across the different branches in the tree of life. As the most recent common ancestor for humans and octopuses lived around 750 million years ago, experts believe that many similarities, from similar camera-like eyes to maps of neural activities, evolved separately in a process known as convergent evolution. While these similarities shed light on evolution's independent paths, they also offer valuable insights for fields like soft robotics and regenerative medicine. Occasionally, unique individuals—like an octopus with an unexpected number of limbs—can provide even deeper clues into how this remarkable nervous system functions and adapts. Nine arms, no problem In 2021, researchers from the Institute of Marine Research in Spain used an underwater camera to follow a male Octopus vulgaris, or common octopus. On its left side, three arms were intact, while the others were reduced to uneven, stumpy lengths, sharply bitten off at varying points. Although the researchers didn’t witness the injury itself, they observed that the front right arm—known as R1—was regenerating unusually, splitting into two separate limbs and giving the octopus a total of nine arms. “In this individual, we believe this condition was a result of abnormal regeneration [a genetic mutation] after an encounter with a predator,” explains Sam Soule, one of the researchers and the first author on the corresponding paper recently published in Animals. The researchers named the octopus Salvador due to its bifurcated arm coiling up on itself like the two upturned ends of Salvador Dali’s moustache. For two years, the team studied the cephalopod’s behavior and found that it used its bifurcated arm less when doing “riskier” movements such as exploring or grabbing food, which would force the animal to stretch its arm out and expose it to further injury. “One of the conclusions of our research is that the octopus likely retains a long-term memory of the original injury, as it tends to use the bifurcated arms for less risky tasks compared to the others,” elaborates Jorge Hernández Urcera, a lead author of the study. “This idea of lasting memory brought to mind Dalí’s famous painting The Persistence of Memory, which ultimately became the title of the paper we published on monitoring this particular octopus.” While the octopus acted more protective of its extra limb, its nervous system had adapted to using the extra appendage, as the octopus was observed, after some time recovering from its injuries, using its ninth arm for probing its environment. “That nine-armed octopus is a perfect example of just how adaptable these animals are,” Pelled adds. “Most animals would struggle with an unusual body part, but not the octopus. In this case, the octopus had a bifurcated (split) arm and still used it effectively, just like any other arm. That tells us the nervous system didn’t treat it as a mistake—it figured out how to make it work.” Kenna Hughes-Castleberry is the science communicator at JILA (a joint physics research institute between the National Institute of Standards and Technology and the University of Colorado Boulder) and a freelance science journalist.

Great star corals in the grip of disease have been saved with probiotics — beneficial bacteria that attack or displace invading pathogens or possibly trigger immune responses to them. What’s causing this deadly disease remains unidentified. But researchers at the Smithsonian Marine Station in Fort Pierce, Fla., were able to successfully halt progression of the disease’s symptoms, the team reports June 5 in Frontiers in Marine Science. The condition is called stony coral tissue loss disease and is characterized by white lesions that lead to the loss of polyps — tiny soft-bodied organisms similar to sea anemones — blanketing coral. Eventually, nothing but the white coral skeleton is left behind. The disease emerged in Florida in 2014 and has spread rampantly throughout the Florida Keys and the Caribbean. A great star coral (M. cavernosa) colony is infected with stony coral tissue loss disease on the coral reef in Fort Lauderdale. The lesion, where the white band of tissue occurs, typically moves across the coral, killing coral tissue along the way. Kelly Pitts/Smithsonian Researchers suspect that the disease is bacterial in nature. Antibiotic treatments can offer a quick fix, but these drugs do not prevent reinfection and carry the risk of the mysterious pathogen building resistance against them. So, in late 2020, the Smithsonian group tried for a more sustainable solution, giving probiotics to 30 infected great star coral colonies. The helpful microbes came from corals tested in the lab that showed resistance to the disease. “We noticed that one of the coral fragments would not get infected … so one of the first things we did was try to culture the microbes that are on this coral,” says microbiologist Blake Ushijima, who developed the probiotic used in the team’s experiment. “These microbes produce antibacterial compounds … and one had a high level of activity against bacteria from diseased corals,” acting as a “pro” biotic, by somehow neutralizing pathogens. The identified microbe, a bacterium called McH1-7, became the active ingredient in a paste delivered by divers to several infected colonies. They covered these colonies with plastic bags to immerse them in the probiotic solution, injecting the paste into the bags using a syringe. They also applied the paste directly to other colonies, slathering lesions caused by the disease. A probiotic paste of McH1-7 is applied to the disease lesion of a great star coral (M. cavernosa) colony infected with stony coral tissue loss disease. The paste was then smoothed flat with a gloved hand so that all apparently infected tissue was covered by the lesion-specific treatment.Kelly Pitts/Smithsonian For two and a half years, the team monitored the corals’ health. The probiotics slowed or stopped the disease from spreading in all eight colonies treated inside bags. On average, the disease’s ugly advance was held to only 7 percent of tissue, compared with an aggressive 30 percent on untreated colonies. The paste put directly on the coral had no beneficial effect. The results are encouraging, but coauthor Valerie Paul cautions against declaring the probiotic a cure. She doubts the practicality of swimming around with heavily weighted plastic bags and putting them on corals. And, she points out, the study was limited to one species of coral, when the disease plagues over 30. Sponsor Message Still, Ushijima considers the study a proof of concept. “The idea of coral probiotics has been thrown around for decades, but no one has directly shown their effects on disease in the wild,” he says. “I think it’s very exciting because it’s actually opening the door to a new field.”

They can also be used to help threatened coral reefs. A bacterial probiotic has helped slow the spread of stony coral tissue loss disease (SCTLD) in wild corals in Florida that were already infected with the disease. The findings are detailed in a study published June 5 in the journal Frontiers in Marine Science and show that applying this new probiotic treatment across coral colines helped prevent further tissue loss. What is stony coral tissue loss disease (SCTLD)? SCTLD first emerged in Florida in 2014. In the 11 years since, it has rapidly spread throughout the Caribbean. This mysterious ailment has been confirmed in at least 20 other countries and territories. Other coral pathogens typically target specific species. SCTLD infects more than 30 different species of stony corals, including pillar corals and brain corals. The disease causes the soft tissue in the corals to slough off, leaving behind white patches of exposed skeleton. The disease can devastate an entire coral colony in only a few weeks to months.  A great star coral (Montastraea cavernosa) colony infected with stony coral tissue lossdisease (SCTLD) on the coral reef in Fort Lauderdale, FL.

The exact cause of SCTLD is still unknown, but it appears to be linked to some kind of harmful bacteria. Currently, the most common treatment for SCTLD is using a paste that contains the antibiotic amoxicillin on diseased corals. However, antibiotics are not a silver bullet. This amoxicillin balm can temporarily halt SCTLD’s spread, but it needs to be frequently reapplied to the lesions on the corals. This takes time and resources, while increasing the likelihood that the microbes causing SCTLD might develop resistance to amoxicillin and related antibiotics. “Antibiotics do not stop future outbreaks,” Valerie Paul, a study co-author and the head scientist at the Smithsonian Marine Station at Fort Pierce, Florida, said in a statement. “The disease can quickly come back, even on the same coral colonies that have been treated.” Finding the right probiotic Paul and her colleagues have spent over six years investigating whether beneficial microorganisms (aka probiotics) could be a longer lasting alternative to combat this pathogen. Just like humans, corals are host to communities known as microbiomes that are bustling with all different types of bacteria. Some of these miniscule organisms produce antioxidants and vitamins that can help keep their coral hosts healthy.  First, the team looked at the microbiomes of corals that are impervious to SCTLD to try and harvest probiotics from these disease-resistant species. In theory, these could be used to strengthen the microbiomes of susceptible corals.  They tested over 200 strains of bacteria from disease-resistant corals and published a study in 2023 about the probiotic Pseudoalteromonas sp. McH1-7 (or McH1-7 for short). Taken from the great star coral (Montastraea cavernosa), this probiotic produces several antibacterial compounds. Having such a stacked antibacterial toolbox made McH1-7 an ideal candidate to combat a pathogen like SCTLD. They initially tested McH1-7 on live pieces of M. cavernosa and found that the probiotic reliably prevented the spread of SCTLD in the lab. After these successful lab tests, the wild ocean called next. Testing in the ocean The team conducted several field tests on a shallow reef near Fort Lauderdale, focusing on 40 M. cavernosa colonies that showed signs of SCTLD. Some of the corals in these colonies received a paste containing the probiotic McH1-7 that was applied directly to the disease lesions. They treated the other corals with a solution of seawater containing McH1-7 and covered them using weighted plastic bags. The probiotics were administered inside the bag in order to cover the entire coral colony.   “This created a little mini-aquarium that kept the probiotics around each coral colony,” Paul said. For two and a half years, they monitored the colonies, taking multiple rounds of tissue and mucus samples to see how the corals’ microbiomes were changing over time. They found that  the McH1-7 probiotic successfully slowed the spread of SCTLD when it was delivered to the entire colony using the bag and solution method. According to the samples, the probiotic was effective without dominating the corals’ natural microbes.  Kelly Pitts, a research technician with the Smithsonian Marine Station at Ft. Pierce, Floridaand co-lead author of the study treats great star coral (Montaststraea cavernosa) colonies infected with SCTLD with probiotic strain McH1-7 by covering the coral colony in a plastic bag, injecting a probiotic bacteria solution into the bag and leaving the bag for two hours to allow for the bacteria to colonize on the coral.

Fighting nature with nature While using this probiotic appears to be an effective treatment for SCTLD among the reefs of northern Florida, additional work is needed to see how it could work in other regions. Similar tests on reefs in the Florida Keys have been conducted, with mixed preliminary results, likely due to regional differences in SCTLD. The team believes that probiotics still could become a crucial tool for combatting SCTLD across the Caribbean, especially as scientists fine tune how to administer them. Importantly, these beneficial bacteria support what corals already do naturally.  “Corals are naturally rich with bacteria and it’s not surprising that the bacterial composition is important for their health,” Paul said. “We’re trying to figure out which bacteria can make these vibrant microbiomes even stronger.”
