ZSI scientists discover new wolf spider species in Sunderbans
This finding marks the first recorded instance of the genus Piratula in India, a group of wolf spiders predominantly found across Asia, with limited distribution in Europe and North America, a ZSI statement said on Friday.
'The newly identified species, Piratula acuminata, belongs to the family Lycosidae, commonly known as wolf spiders," the statement added.
'Unlike web-building spiders, these agile predators are ground-dwelling and ambush their prey," Souvik Sen, lead researcher from ZSI, said.
He described the species as a medium-sized spider, approximately 8-10 millimeters in length, characterised by its pale creamy white coloration interspersed with brown, chalk-white spots on its abdomen, and a pair of light brown stripes towards the rear.
The distinctive structural intricacies of its genitalia were key to its identification as a novel species.
'The unique morphological features of this spider immediately indicated it was an undocumented species," Sen added.
'We conducted extensive morphological analysis over several weeks to confirm our findings," he added.
The research team, comprising Souvik Sen and Sudhin PP from ZSI, Kolkata, along with Pradeep M. Sankaran from Sacred Heart College, Cochin, has published their detailed scientific account in the latest issue of Zootaxa, a peer-reviewed scientific journal.
This discovery on Sagar Island, the largest island within the Sundarbans deltaic complex, reinforces the ecological richness of this UNESCO World Heritage Site, Sen said.
The island's unique ecosystems, shaped by alluvial deposits from the Ganga River, include vital mudflats and estuarine waters supporting a diverse array of flora and fauna.
'Every new species we discover is a testament to the incredible natural heritage of this region," ZSI director Dhriti Banerjee said.
'It also serves as a stark reminder of how much we stand to lose if we don't expedite our efforts to protect these habitats."she added. PTI SUS MNB

Very surreal: Rebecca Romijn on returning as Mystique in Avengers: Doomsday
New Delhi, Aug 2 (PTI) Hollywood star Rebecca Romijn says she was surprised to receive a call to be part of the superhero ensemble film 'Avengers: Doomsday" and reprise the fan-favourite role of mutant Mystique from the 'X-Men" movies. Romijn, who stars in the third season of her popular show 'Star Trek: Strange New Worlds" currently streaming on JioHotstar, said she is in the midst of filming for the much-awaited project and the whole experience has been 'wonderful" so far. 'Very surreal. It was a call that was very unexpected for me and very thrilling. We're currently shooting and filming now and it's been wonderful so far," Romijn told PTI in an interview. The 52-year-old actor originated the role of Mystique in the 'X-Men" trilogy in the 2000s, portraying the shape-shifting mutant with a mix of cunningness and menace. Romijn first played the part in 2000's 'X-Men", followed by 'X2" (2003), and 'X-Men: The Last Stand" (2006). She also made a brief cameo in 'X-Men: First Class", in which Jennifer Lawrence took over the character from her. In 'Doomsday", she is returning along with a host of legacy 'X-Men" characters — Patrick Stewart as Charles Xavier aka Professor X, Ian McKellen as Magneto, Kelsey Grammer as Hank McCoy aka Beast, Alan Cumming as Nightcrawler and James Marsden as Scott Summers aka Cyclops. The movie, which will mark the return of 'Iron Man" star Robert Downey Jr in the Marvel Cinematic Universe (MCU) but in the avatar of supervillain Victor Von Doom aka Doctor Doom, will come out in theatres in December 2027. 'Star Trek: Strange New Worlds" features Romijn as Commander Una Chin-Riley, also known as Number One, the highly capable first officer aboard the USS Enterprise, serving under Captain Christopher Pike, played by actor Anson Mount. As a mother, Romijn said she consciously picks roles that serve as positive role models for her daughters and young girls watching globally. 'I am a mother of girls and so it's very important to choose roles that are positive role models for my daughters and for other young ladies around the world. And I take it into consideration. I don't take it lightly, especially when I'm leaving my daughters to go away on location and have to be away from them for long periods of time." The actor, also known for films like 'The Punisher", 'Femme Fatale" and 'Man About Town", said she aims to take on work she can be proud of, especially character she'll feel good about sharing with her children. 'I want to be proud of the work that I get to come back and show them… especially within the 'Star Trek' and genres of science fiction and comic book… I really enjoy playing female characters that are multifaceted and often just as strong as the male characters. It's important to me," she said. Romijn said both Una and Mystique are 'mutants to a certain extent" but they deal with their identities in very different ways. 'There are a lot of similarities between playing the mutant Mystique and playing a genetically modified character on Star Trek. They're both mutants to a certain extent. With Mystique, the difference is that she chose to not hide who she actually is and Una chose to hide her mutation. 'But the big difference is that Una chose to hide it until she was forced to go to trial and get cleared for it. And Mystique has chosen to not hide it and let that drive her," she said, adding that Mystique is a 'more dangerous character". Christina Chong, Romijn's co-star, plays La'an Noonien-Singh in 'Star Trek: Strange New Worlds" and reflected on her character's emotional and genetic legacy. La'an is a descendant of Khan Noonien Singh, the infamous genetically enhanced villain from Star Trek lore. She carries not only augmented DNA, but also the heavy burden of a legacy — a name synonymous with fear, destruction, and historical trauma. She teased that La'an will confront this legacy in the new season, especially in the upcoming episode 'Four-and-a-Half Vulcans". 'She has recessive augmented DNA and so she does struggle with that. But for the most part of season three, she's allowing herself to let go a little more. She's fought her biggest enemy and won, and therefore she's opened up to a lighter side of herself and to potential love," she added. Chong also said that playing La'an helped her explore deeper emotional truths about herself. In the show, the character comes across as guarded and has a fear of connection, a theme many people relate to. top videos View all 'The fear aspect of connecting or finding love. The fear of losing it and therefore holding back. Although I don't hold back in my personal life, the fear is very real there. The abandonment issue that we all have in some way. Although I don't stop myself, there is a hurdle to jump over," she said. The third season of 'Star Trek: Strange New Worlds" also stars Ethan Peck, Jess Bush, Celia Rose Gooding, Melissa Navia, Martin Quinn, and Babs Olusanmokun.

Ready to share my learnings for Gaganyaan mission: Shubhanshu Shukla
In his first public interaction since returning from space, astronaut and Group Captain Shubhanshu Shukla on Friday said he is focussed on setting to put his learnings to use for India's Gaganyaan mission scheduled for 2027. Shukla became the second Indian to travel to space after Rakesh Sharma's sojourn as part of the Soviet Russian mission in 1984. (PTI photo) Shukla recalled speaking to Prime Minister Narendra Modi and called it a very moving moment. 'It was a moment of returning to space after 41 years. But it is the beginning of what I like to call the second orbit. This time, we are ready to lead, not just fly,' said Shukla during a post mission media briefing along with three other Axiom-4 mission crewmates. 'From launch to recovery, the learnings of one year feels like more than a year. The learnings and knowledge is going to prove invaluable for our (Gaganyaan) mission', he said. On June 25, Dragon Grace spacecraft lifted off with mission pilot Shukla along with commander Peggy Whitson and mission specialists Sławosz Uznański-Wiśniewski and Tibor Kapu, marking the first human space flight for India, Poland and Hungary in 40 years. Shukla became the first Indian astronaut to go to space in more than 40 years and the first on the International Space Station (ISS). Of the 21-days in space, Ax-4 crew members spent 18 days on ISS. Expressing his gratitude to the Indian government, Isro, Indian Air Force, NASA, SpaceX, the 39-year-old said spending 21 days in space exceeded his expectations.

While preparation for the Ax-4 mission began on August 1 last year, Shukla said the experience of being in space, performing experiments and understanding how the body reacts to microgravity adds to what they were trained for through the year. 'We got comfortable fast. After a couple of days, it didn't matter if we were next to the floor or the ceiling,' he laughed. The Lucknow resident shed light on how it took him days to adjust to gravity. 'It takes some time to get back to what we did all our lives. With the training to gain balance and strength, I was back to normal in 3-4 days,' said Shukla. 'The rehab is going great, it feels normal and I am ready for another mission again', he said.

What Happens When An Astronaut Comes Home? Shubhanshu Shukla Shares His Gravity Shock
Indian astronaut Shubhanshu Shukla, a part of the historic Axiom-4 mission, is giving insightful comments about his re-accustomization to Earth's gravity following a 20-day stay on the International Space Station (ISS). At a virtual press conference on Friday, Shukla explained how even ordinary objects suddenly felt impressively heavy, narrating a hilarious experience when he dropped a laptop anticipating it to float. Shukla and his Axiom-4 crew members, who took off from Kennedy Space Centre in Florida on June 25 and landed on Earth on July 15, interacted with the media online, reminiscing about their experience on the mission. This was a historic event for India, as Shukla became the second Indian to travel to space, after Wing Commander Rakesh Sharma's trailblazing journey in 1984. VIDEO | "I remember the homework our PM had given me and I have completed it very well," says Indian Astronaut, Group Captain Shubhanshu Shukla, the mission pilot for Axiom Mission 4 (Ax-4). (Source - Third party) (Full video available on PTI Videos - — Press Trust of India (@PTI_News) August 1, 2025 "Back in space after 41 years, a Bharatiya, but not a single jump this time. It was the launch of India's second orbit. And this time, we are prepared, not to fly, but to lead," declared Shukla, underlining the re-entry of India in space exploration. For Lucknow native Shukla, a highlight was his meeting with the "Prime Minister of Bharat" on June 28, with the Indian flag visibly drifting behind him. He termed this as a watershed moment marking India's re-entry into international space chatter as an equal contributor. The astronaut spoke openly about having to re-adjust to the gravitational pull of the Earth. He remembered his mobile phone feeling "heavy" when a colleague asked for a photo, a sharp contrast to its weightlessness in space. In a second funny story, he remembered dropping his laptop near the bed, expecting it to float. "Fortunately, the floor was carpeted, so no harm was done," he laughed. As for the Axiom-4 mission itself, Shukla explained that it "surpassed his expectations" and offered priceless learning experiences that will be invaluable to India's future Gaganyaan mission. He considered his mission to be more than simply that of a spacefarer, envisioning himself as a "messenger demonstrating what's achievable." Shukla, who is expected to return to India in mid-August, said that he religiously did all "homework" that Prime Minister Modi gave him while he was on the space station, including keeping a careful record of all details of the mission. He was keen to offer his recorded insights, sure that this information "is going to prove extremely useful and crucial for our own Gaganyaan mission." Emphasising the wider mission of these space missions, Shukla pointed to their principal aim: to encourage the next generation and inculcate them with the confidence that they too can be explorers. He pointed to the mission's initial success in this respect, with children already asking for ways to become astronauts.
