Two new crocodile species discovered. They are different from others
Scientists are stunned to discover two previously unknown species of crocodiles living on the island of Cozumel and the other on the atoll of Banco Chinchorro, both off the Yucatan Peninsula.The two new species are yet to be officially named.The discovery challenges previous assumptions about the American crocodile and highlights the urgent need for conservation efforts, the researchers say that even as the population of the species is stable, it's still just a handful.advertisement

They discovered striking levels of genetic differentiation that led the researchers to conclude that these populations were not simply variants of Crocodylus acutus. "Biodiversity is disappearing faster than we can discover what we're losing. Most species of crocodiles are already endangered, and rapid shoreline development threatens nearly every population. Our research aimed to uncover the true diversity of crocodiles on these isolated islands," Biology Professor Hans Larsson, the principal investigator said.advertisementHe added that these results were unexpected. "We assumed Crocodylus acutus was a single species ranging from Baja California to Venezuela and across the Caribbean. Our study is the first to extensively explore genomic and anatomical variation in these animals," Larsson said. The newly identified species live in small, isolated populations, each numbering fewer than 1,000 breeding individuals. While both populations appear stable, their limited numbers and habitat restrictions make them vulnerable."Now that we recognize these crocodiles as distinct species, it's crucial to protect their habitats. Limiting land development and implementing careful conservation strategies on Cozumel and Banco Chinchorro will be key to ensuring their survival," Larsson said.

Explained: ‘Realising the return'— how an Indian became part of Axiom-4
In June 2023, during Prime Minister Narendra Modi's state visit to Washington, India and the US announced a decision to finalise a strategic framework for human spaceflight cooperation. It was also revealed that Indian and American space agencies, Indian Space Research Organisation (ISRO) and National Aeronautics and Space Administration (NASA), would mount a joint effort to enable an Indian astronaut to travel to the International Space Station (ISS) by 2024. The announcement came as a surprise. Till then, it was understood that the first Indians to travel to space after Rakesh Sharma's historic flight in 1984 would ride the Gaganyaan mission which ISRO had been preparing for since 2018, when Modi unveiled India's ambition to send humans into space by 2022. The 2022 timeline could not be adhered to. But astronauts had been selected and trained, and systems were under development and being tested. The 2023 announcement offered India an opportunity to get real-life experience for one of its astronauts ahead of the Gaganyaan mission. Only three nations — the US, Russia and China — have a human spaceflight programme of their own. Shubhanshu Shukla's flight, which came about on the back of the 2023 announcement, is thus being seen as another preparatory step ahead of the Gaganyaan mission. A growing partnership It has since emerged that the 2023 announcement was the result of at least a few years of discussions between India and the US. Their space agencies have been working on a joint NISAR (NASA-ISRO Synthetic Aperture Radar) mission for over a decade now, enabling a closer-than-ever partnership. That mission is finally ready now, and likely to be launched in the next few weeks from Sriharikota, Andhra Pradesh. The need to further strengthen their partnership, possibly through a joint human spaceflight programme, had been broached several times during these interactions. This took place particularly after ISRO demonstrated its advanced capabilities with missions, such as Chandrayaan and Mangalyaan, and the development of sophisticated space systems. This closer collaboration was formalised a couple of months after Modi's Washington visit in June 2023, when India signed the Artemis Accords, a US-devised set of principles for responsible behaviour and cooperation in space exploration, particularly in lunar and deep planetary missions. It paved the way for unprecedented collaboration between the two countries in space-related matters, the first benefits of which have begun to unfold with the Axiom-4 mission. Axiom Space's invitation Shortly after the Artemis Accords were signed, Axiom Space, a private US-based space company, invited India to participate in its mission to the ISS. Axiom Space has been the first and till now the only beneficiary of a NASA programme to enable private US industry to send commercial crewed missions to low-earth orbits and the ISS. This is part of NASA's endeavour to build capabilities in the private sector while it focuses on science and planetary exploration. Axiom Space has sent three multinational missions to the ISS so far, each carrying four astronauts. The inaugural mission, in 2022, marked the first instance of an all-private crew making its way to the ISS. None of the astronauts were affiliated to, or selected by, any national space agency, though one of them had been a former NASA astronaut. The other three were businessmen. The second mission in 2023 also had three private individuals, and was commanded by Peggy Whitson, a former NASA astronaut and the world record holder for having spent the maximum number of days in space. The third mission last year had an all-European crew, with the first Turkish national to ever go into space. For its fourth mission on Wednesday, on which Shukla will travel to the ISS, Axiom Space invited three countries who had last been to space more than 40 years ago — India (1984), Hungary (1978) and Poland (1980) — with Whitson named commander once again. Aptly, the mission has been themed 'Realize the Return'. Anonna Dutt is a Principal Correspondent who writes primarily on health at the Indian Express.

The whole world is closely watching it: Union Minister Jitendra Singh on Axiom4
Nice [France], June 10 (ANI): Union Minister Jitendra Singh spoke about the exclusive missions which will be performed by Indian astronaut Group Captain Shubhanshu Shukla during his Axiom4 space mission. He also mentioned the world recognising India's growth and capabilities and said that this has been possible due to the changes brought in the space sector in recent times. In a video released by the Office of Jitendra Singh, speaking about Gaganyaan mission, he said, 'Gaganyaan is a very ambitious mission as far as ISRO is concerned. The whole world is closely watching it.' He added, 'Gaganyaan will also involve docking and undocking, which will happen in this. Once they go up, it will take about 28 hours, then after 28 hours, it will reach about 400 kilometres from the surface of Earth, which is in American physiology, about 250 miles, and there the docking would happen. They would then enter into the space station. And remain there for a minimum of about two weeks, which could also be extended. So the experience: getting accustomed to that kind of exercise walking into and walking out would also be required in case of Gaganyaan, and also several future experiments, and more so India's own space station. We plan to have our own exclusive space station by 2035, which will be known as Bharat Space Station, and for that also, this experience is going to come in handy.' Speaking about the role which will be performed by Group Captain Shubhanshu Shukla, he said, 'This time, Shubhanshu Shukla is going to play a very important role. He is going to have the most critical role because he will perform experiments which are exclusively going to have a bearing on the future space missions, not only those of India, also of NASA and other agencies. And I'm also glad to mention that it keeps up the spirit of the whole of science and the whole of government, which PM Modi keeps emphasising time and again. We got ISRO involved in an official MoU with the Department of Biotechnology. And as of now, Shubhanshu is scheduled to perform six sets of experiments. A) For example, about life sciences- the physical, physiological, and cognitive effects of being in space for a long while, which would affect the human body.' He added, 'B) of course, the behavioral responses resulting from constant watching of the computer screen which is mandatory for all the astronauts. C) He is also going to experiment on the body's response in extreme conditions. The effect of microgravity on muscle dysfunction and besides that, some plant-related research like how the cyanobacteria behave in microgravity, which could have a bearing on the production of food elements in space in times to come.' He said, 'These are very futuristic experiments which are exclusively assigned to Shubhanshu. Therefore, it's a great breakthrough. This is a moment which would make our founding fathers proud- Vikram Sarabhai, Satish Dhawan. India today has reached that pedestal where we are looked upon as not junior partners, not as followers, but as partners who offer cues to others to follow. And this could be possible because of the reorientation of the space reforms, the opening of the space sector to the private players and it could not have been possible without the political will of the government in place.' Union Minister Jitendra Singh thanked PM Modi for his leadership. 'I have to thank PM Modi for he has the cpacity to make out-of-box decisions, break the taboos of the past because for six, seven decades we got conditioned to live with the belief that space has to act behind the veil of secrecy and it is not to be opened up to the private sector. Giving up that mindset, we are now following same global strategies, parameters, in fact, marching ahead of other nations as well.' He elaborated, 'We are now equal partners. The decision to have an Astronaut from India was taken and the offer was made to India incidentally when PM Modi was on a visit to Washington DC when President Biden was in place. So you can see there is also a reflection of the recognition of the Indian capabilities, Indian human resource, which is quite a departure from the earlier times when the capabilities of Indians were not taken seriously. That perception about India has also undergone a change.' The Axiom-4 mission launch has been postponed to June 11, 2025, due to unfavorable weather conditions. The Indian Space Research Organisation (ISRO) announced that the mission, carrying Indian astronaut Group Captain Shubhanshu Shukla to the International Space Station (ISS), will now lift off at 5:30 PM IST on June 11. ISRO wrote on X, 'Launch of Axiom-4 mission to International Space Station: Due to weather conditions, the launch of Axiom-4 mission for sending Indian Gaganyatri to International Space Station is postponed from 10th June 2025 to 11th June 2025. The targeted time of launch is 5:30 PM IST on 11th June 2025: Dr V Narayanan, Chairman ISRO/ Secretary DOS / Chairman Space Commission.' Union Minister Jitendra Singh also shared the details in a post on X. He noted that due to adverse weather conditions, the mission has been postponed by a day. He wrote on X, 'Update on Axiom-4 Mission to ISS. Due to adverse weather, the launch of the Axiom-4 mission carrying Indian Gaganyatri to the International Space Station is rescheduled from June 10 to possibly June 11, 2025. Further update, if any, will be accordingly shared. New Launch Date: June 11, 2025 Time: 5:30 PM IST.' The Axiom-4 mission crew includes members from India, Poland, and Hungary, marking each nation's first mission to the space station in history and the second government-sponsored human spaceflight mission in over 40 years, according to Axiom Space. Group Captain Shubhanshu Shukla will be India's second national astronaut to go to space since 1984. Group Captain Shubhanshu Shukla is part of Axiom Space's fourth private astronaut mission (Ax-4), marking a historic moment for India's space collaboration with NASA. Slawosz Uznanski, European Space Agency (ESA) project astronaut, will be the second Polish astronaut since 1978. Tibor Kapu will be the second national Hungarian astronaut since 1980. Peggy Whitson will command her second commercial human spaceflight mission, adding to her standing record for the longest cumulative time in space by an American astronaut. (ANI)

'What a magical thing that is': Carl Sagan's wise words on reading books are the fresh breeze we need amid digital brain rot
A resurfaced 1977 Carl Sagan clip warns against intellectual decline, a vital message today as "brain rot" proliferates. Sagan championed reading as a magical connection to past minds and stressed nurturing childhood curiosity. (Images: X/@carlsagandotcom , iStock) A resurfaced video of legendary astronomer Carl Sagan from a 1977 appearance on The Tonight Show is sparking crucial conversations, offering profound insights amidst widespread concerns about dwindling attention spans and the pervasive "brain rot" of the digital era. As screens dominate and algorithms dictate our daily lives, Sagan's wise words on the sheer power of reading books and nurturing curious minds feel less like a relic of the past and more like an urgent plea for our intellectual the captivating 1977 clip, Sagan, a master communicator of science, articulated the almost unbelievable power held within a book. "The whole idea of what happens when you read a book I find absolutely stunning," he told Johnny Carson. He marveled at how "some product of a tree with little black squiggles on it" could open up, revealing "the voice of someone speaking who may have been dead 3,000 years, and yet there he is talking directly to you. What a magical thing that is." This timeless connection through the written word, a direct link to minds across centuries, stands in stark contrast to the fleeting nature of digital content. Sagan didn't stop at the magic of books; he delved into the inherent curiosity of children, a vital "natural resource" he believed we are tragically wasting. He observed that children "start out eager, intellectually wide-eyed, asking extremely clever questions." Yet, he lamented, "something happens, by and large, to discourage them."He highlighted how dismissive responses to profound questions, like "Mommy, why is the grass green?", teach children "there's something bad about using the mind." Sagan warned that in perilous times, facing "complex and subtle problems" requires individuals capable of "complex and subtle solutions"—a capacity nurtured through intellectual engagement and curiosity. Sagan's 1977 observations are eerily prescient today. The Oxford 2024 Word of the Year, "brain rot," encapsulates widespread anxiety about declining attention spans. Data from Gallup and the Bureau of Labor Statistics show a steady decline in American reading habits. In a conversation on NPR, author Elaine Castillo noted that "massive corporations have essentially captured the capacities in us for reading," offering "momentary dopamine hits" that replace reading's restorative aspects. Abdullah Shihipar of Brown University added that reading a book requires a higher "mental load" than casual scrolling, and studies suggest reading physical media is "superior" to screen reading, which often encourages skimming. The education sector sounds a loud alarm. A former English and digital arts teacher, Hannah, recently resigned with a viral video, lamenting that "a lot of kids don't know how to read," and that AI tools are eroding critical thinking. She witnessed students unable to write basic sentences, and essays produced entirely by ChatGPT, with students showing little concern over plagiarism. Hannah's drastic suggestion: "We need to cut it off. Let them learn how to think again."Abdullah Shihipar, in an NPR conversation, cited a Duke study showing a 12% decline in reading comprehension when AI tools were used. Elaine Castillo articulated a deeper fear: that we might "abdicate our own humanity and our capacity to read, to contemplate, to wrestle with difficult concepts." She emphasized reading's role in building empathy and fostering a "capacity for defiance." The statistics are stark: roughly half of American adults read below a sixth-grade level. Beyond cognitive benefits, reading boasts tangible health advantages; Shihipar mentioned a study indicating a 20% decrease in mortality for book readers, independent of wealth or age. Carl Sagan's powerful message from decades ago offers a vital path forward. His emphasis on the magic of books and the nurturing of intellectual curiosity is not just nostalgic; it's a strategic blueprint for preserving our minds, our empathy, and our ability to navigate the complexities of our world. It's time to heed his timeless wisdom.
