New dragonfly species discovered in Western Ghats
The discovery was made by researchers from the Travancore Nature History Society (TNHS) and collaborating institutions following field surveys and larval rearing experiments. The findings were published in the journal Entomon on June 30.
The new species has been named in honour of Abraham Samuel, a pioneer in odonatology from Kerala. It is endemic to the southern and central Western Ghats and has been found in multiple forest landscapes in Kerala and Karnataka.
"This discovery highlights the hidden diversity within India's forests and the value of close morphological study," said Kalesh Sadasivan, lead author and odonate researcher of TNHS. "Our rearing of larvae and dissection of adults revealed distinct characters not found in L. flava," Sadasivan added.
The new species breeds in phytotelmata, which are small pools of water in tree holes and exhibits strong sexual dimorphism.

Males possess uniquely shaped hamules, whereas females are jet-black with prominent yellow triangular spots. Its distribution ranges from lowland rainforests to mid-elevation evergreen and deciduous forests (50–1100m ASL), yet it remains rare and localised.
"Lyriothemis abrahami exemplifies how species can be overlooked when relying on superficial characters or juvenile forms," said Muhamed Jafer Palot of the Zoological Survey of India.
"It was misidentified for over a decade due to similarities with L. flava."
The study revealed that specimens from earlier reports, including a female collected in 2013, belonged to this new species. The research team conducted comparative analyses with historical material and illustrated the diagnostic traits.
"The discovery raises Kerala's odonate count to 191 species, including 78 endemics," said Vinayan Padmanabhan Nair, co-author.
This discovery reinforces the importance of conserving forest microhabitats. Tree holes, often overlooked, are critical breeding sites for species such as L. abrahami. The loss of mature trees and canopy cover threatens these delicate niches.
"This dragonfly is not just a species, it's an indicator of forest health," said Jebine Jose, co-author and field ecologist. "Conserving its habitat helps protect many other unseen organisms."

The Role of Arm Swing in Walking: How to Use Your Arms for Better Momentum
Swinging your arms while walking isn't just a casual habit; it's a biomechanical advantage. This natural motion enhances walking efficiency, boosts momentum, and improves balance. Research indicates that arm swinging conserves energy, engages upper body muscles, and promotes better posture, transforming a simple walk into a more effective workout. Walking is one of the most effective and simple forms of physical activity. Though walking may look simple, the mechanics behind it are far more complex. While walking, people swing their arms. Ever wondered why we do this? Swinging your arms can significantly impact your walking efficiency, speed, and has other health benefits. Arm movement not only boosts momentum but also improves balance, posture, and overall energy efficiency. Let's understand how the power of arm swing can transform a daily stroll into a more effective exercise. Arm swing matters Most of us swing our arms when we walk or run. Most importantly, our arms and legs are in sync with each other. This is because the human body is designed to move in a coordinated manner. And the arm swing is there to counterbalance leg movement. When you step forward with your right leg, your left arm naturally swings forward to maintain balance and reduce rotational forces on the torso. This natural rhythm minimizes energy expenditure and stabilizes the body. A study published in 2014 in The Journal of Experimental Biology found that swinging arms save energy. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Discover Why These Off-Plan Dubai Apartments Sell Fast? Binghatti Developers FZE Read More Undo When it comes to running, swinging arms counterbalance the momentum of a person's legs, providing stability to the runner. The study observed 13 participants and compared the energy cost of running in four different positions. They looked at the oxygen consumption and carbon dioxide production while running. The researchers found that swinging your arms uses 3% less energy than keeping your hands behind your back, 9% less energy than folding your arms over your chest, and 13% less energy than running with your hands above your head. The study notes that the muscular power used while holding the arms in unusual positions may contribute to some of the extra energy cost. 'Overall, we believe that our comprehensive approach to testing our running arm swing hypothesis provides the most conclusive evidence to date that arm swing provides a metabolic benefit during human running,' the study author concluded. Indian Astronaut Shubhanshu Shukla Grows Moong, Methi In Space Aboard Axiom-4 Mission How to use your arms for better momentum No doubt, swinging arms while walking and running can offer some benefits. But how do you do it the right way? Well, being mindful is important. Focus on the natural rhythm of your arms and legs. For best results, avoid carrying objects like phones or bags in your hands, which can disrupt the swing. Incorporating proper arm swing into your walking routine is a simple yet powerful way to improve efficiency, burn more calories, and also improve overall health. Next time you hit the pavement, let your arms lead the way. Along with boosting momentum, arm swing also engages the upper body. Consider it as a low-impact way to tone muscles in the arms, shoulders, and core. You can also burn more calories than your regular walk while swinging your arms. Think of it as a more effective full-body workout. Arm swing also improves posture, as it engages the core and keeps the torso upright, and can reduce strain on the lower back.

Why Shubhanshu Shukla matters so much for India's space tech
Indian Air Force Group Captain Shubhanshu Shukla has returned to Earth after an 18-day journey aboard the International Space Station (ISS) as part of the Axiom-4 mission . But his touchdown will translate into a big takeoff -- India's indigenous human spaceflight programme. Shukla's safe splashdown off the California coast marked more than just the end of a pioneering spaceflight; it symbolized a new chapter for India's ambitions in space exploration. Shukla's mission represents the country's first human presence aboard the ISS and serves as a vital stepping stone toward Gaganyaan , India's mission to send people into space using its own technology. His experience offers both practical insight and symbolic momentum to a nation on the brink of joining the elite club of spacefaring powers with crewed capabilities. What Shukla achieved on the Axiom-4 mission As the pilot of the Axiom-4 mission, Shubhanshu Shukla played a critical role in operating SpaceX's Crew Dragon spacecraft, including its launch, docking, undocking, and re-entry. His position made him the first Indian military pilot to execute real-time operations aboard a commercial spacecraft alongside a veteran like Peggy Whitson. This exposure to both the technical and psychological challenges of space travel was critical for an astronaut preparing for India's future crewed missions. In orbit, Shukla was actively involved in over 60 scientific experiments , a significant portion of which were India-led. These included studies on plant growth using Indian staples like moong and methi, analysis of cyanobacteria and microalgae for sustainable life-support systems , and experiments involving tardigrades to understand biological resilience in space. Other research explored muscle atrophy, diabetes monitoring, and the physiological effects of prolonged screen exposure in microgravity. These experiments were not abstract exercises. They provide essential insights into the design of life-support and medical systems for long-duration missions, key for India's ambitions in independent space habitation. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like The Top 25 Most Beautiful Women In The World Marvelousa Undo Perhaps more subtly, Shukla also contributed to outreach and education. He interacted remotely with Indian schoolchildren and researchers, offering a glimpse into life aboard the ISS. From daily routines to adapting to life without conventional bathing and handling hygiene through wipes, his lived experience in microgravity offers ISRO a real-world dataset on human adaptation beyond Earth's atmosphere. Also Read | Axiom 4 mission: Indian astronaut Shubhanshu Shukla 'Shux' returns to Earth as Grace splashes down in Pacific Live Events Strategic impact on India's space ecosystem The Axiom-4 mission is far from a standalone achievement. It has directly enhanced India's technical readiness for human spaceflight. Shukla's mission provided ISRO with hands-on feedback on spacecraft systems integration, ground communication protocols, and emergency response procedures, all critical components for the upcoming Gaganyaan mission. The scientific outcomes of his experiments will influence not only mission design but also academic and industrial research within India. From universities to biotech startups, many domestic players were involved in conceptualizing and building the payloads for Axiom-4. This collaborative structure lays the groundwork for a robust space-tech ecosystem within the country. Equally important is the human resource development angle. Shukla's training regimen, which included simulations, quarantine protocols and rigorous health monitoring, serves as a model for preparing future Indian astronauts. It also underscores the physiological and psychological benchmarks ISRO must meet in its astronaut selection and training processes for Gaganyaan. Beyond technology and science, Shukla's participation strengthens India's space diplomacy. The Axiom-4 mission, executed in partnership with NASA and SpaceX, situates India firmly in global commercial and scientific space efforts. This enhances ISRO's credibility as a partner in multinational missions and opens up avenues for joint research and investment. Also Read | PM Modi welcomes Captain Shubhanshu Shukla as Dragon returns to Earth Gaganyaan: The next giant leap India's Gaganyaan programme, for which Shukla and three others have been selected, is designed to send a crew of three astronauts into Low Earth Orbit (LEO) for up to seven days using an indigenously developed launch system and crew module. With its first uncrewed test flights scheduled for 2025 and a human flight targeted for 2027, Gaganyaan will make India the fourth nation -- after the United States, Russia and China -- to independently send humans into space. Technologically, Gaganyaan represents a significant leap. It requires a human-rated launch vehicle, advanced re-entry systems and life-support mechanisms that India is developing from the ground up. It also demands complex ground infrastructure, ranging from astronaut training facilities to mission control networks capable of handling the nuances of human spaceflight. But Gaganyaan is more than a technical challenge. It is a strategic national goal that will elevate India's global standing, drive research in advanced materials and bio-sciences, and serve as a catalyst for broader participation in lunar and interplanetary exploration. It also inspires a new generation of scientists and engineers by placing human spaceflight within the nation's grasp. Why Shukla's mission is a turning point The importance of Shubhanshu Shukla's participation in Axiom-4 goes far beyond the symbolic. It marks India's entry into the practical realities of living and working in space. His training and mission execution create a reference framework for ISRO as it prepares for human flight. The scientific results he helped gather will refine space medicine, agriculture, and life-support technologies. Economically, the mission -- backed by Rs 550 crore in investment -- has already sparked interest and growth in India's nascent space start-up sector. Strategically, it sends a clear message: India is no longer an emerging participant in human spaceflight but an active contributor shaping its future. Shubhanshu Shukla's successful journey aboard Axiom-4 marks a significant inflection point in India's space history. It merges symbolic achievement with functional progress, demonstrating both capability and intent. As India moves closer to launching its own astronauts aboard its own spacecraft, Shukla's experience offers a blueprint as well as a boost.
