Olympic Speed Climbing Champion Sam Watson to Visit Mumbai

Mumbai: When Sam Watson sprints up a 15-metre wall, the world seems to slow down. The 19-year-old American speed climber, an Olympic medallist from Paris 2024 and current world-record holder at 4.64 seconds, has become the face of one of the world’s fastest-growing sports.

Olympic Speed Climbing Champion Sam Watson to Visit Mumbai

Mumbai: When Sam Watson sprints up a 15-metre wall, the world seems to slow down. The 19-year-old American speed climber, an Olympic medallist from Paris 2024 and current world-record holder at 4.64 seconds, has become the face of one of the world’s fastest-growing sports. On November 2, he will trade competition arenas for Mumbai’s High Rock in Powai, offering a rare day of workshops and conversations with India’s burgeoning community of climbers. Speed climbing, once a fringe pursuit of mountaineers, now stands as one of the Olympics’ most electrifying disciplines. The sport demands not just power and agility but precision measured in hundredths of a second. Watson, often hailed as the greatest speed climber of all time, has repeatedly rewritten the record books. His visit marks a milestone for India’s fledgling climbing scene. High Rock, the city’s first commercial climbing facility, opened its walls in December 2024 and has since drawn more than 10,000 enthusiasts. It represents the country’s growing fascination with vertical sports and a reflection of a global shift toward adventure and athleticism fused with technology and training science. During his visit, Sam Watson will conduct Masterclasses for both Kids and Adults, offering a rare opportunity for amateur climbers to learn directly from a global champion and experience his unmatched energy and technique up close. Watson will be joined by Matt Groom, the Official Lead Commentator for the International Federation of Sport Climbing (IFSC). Known as the voice of IFSC World Cups and World Championships, Groom will host a 30-minute talk at High Rock on ‘The Evolution of Climbing in Competitive Sport.’ His insights promise to provide a deep look into the transformation of climbing from niche adventure to Olympic spectacle. Event: Sam Watson, Olympic Medalist and current World Record holder at High Rock Date: November 2, 2025 Location: High Rock, Powai, Mumbai

From Soil to Sunlight

Mango season is at its peak. Ethylene, which acts as a gaseous hormone in plants, plays an important role in ripening of mangoes both naturally and artificially. However, this phytohormone does much more in plants. A team of scientists at the Indian Institute of Science Education and Research (IISER) in Bhopal (which included Nevedha Ravindran, Kavuri Venkateswara Rao and myself) have uncovered an interesting role of ethylene in detecting soil depth and successful emergence of seedlings from underneath the soil during germination. Ethylene production is increased in seeds when they perceive mechanical pressure of soil over them. In natural conditions, when a seed germinates and tries to emerge out of the soil, pressure of soil induces ethylene production and the seedling slowly gets exposed to light.


In a scientific study that we published in the journal New Phytologist, we detail how scientists identified that a protein BBX32 is promoted by ethylene and light, to optimize the timing of successful emergence out of the soil. Soil pressure leads to the production of more ethylene that increases the stability of the BBX32 protein. Light also promotes the accumulation of BBX32 which helps to maintain a hook-like structure at the tip of the growing seedling. The hook allows the seedling to pierce through the abrasive soil particles without damaging the plant tip which gives rise to stems and other above ground parts of the plant. The protein BBX32 helps the plant maintain the hook until conditions are favourable for emergence.


The study was conducted using Arabidopsis thaliana, a widely used model plant. The team compared seedlings with normal levels of BBX32 against those that either lacked the protein or overproduced it. The plants were grown under controlled conditions: on plates with and without ethylene exposure, under layers of sand to mimic soil pressure, and under various wavelengths of light including white, red, blue and far-red. The goal was to determine how ethylene and light interact to influence the behaviour of BBX32 and the timing of hook opening.


The researchers monitored hook angles at different stages of seedling development as the plants transitioned from darkness to light. They also measured the percentage of seedlings able to emerge from beneath the sand. The findings were clear: the more BBX32 present, the higher the success rate of emergence. BBX32, in concert with another protein, PIF3, induces HLS1, which keeps the hook closed until the time is right.


The study offers new insight into how seeds navigate their journey from the subterranean dark to the light above. For farmers, this is more than just academic, given that seedling establishment failures account for a significant share of crop loss. Understanding and manipulating this process could have far-reaching implications for agricultural productivity.


In future, then, ethylene may be valued for more than just ripening fruit. Its role in helping plants emerge into the light could prove just as vital.
