India's first gene-edited sheep developed in Kashmir Agricultural university. All you need to know
Researchers at a Kashmir-based Agricultural university have produced India's first gene-edited sheep, marking a historic milestone in the field of animal biotechnology.
The Sher-e-Kashmir University of Agricultural Sciences and Technology (SKUAST) has called it a "ground-breaking scientific achievement".
The edited sheep contains no foreign DNA, distinguishing it from transgenic organisms and paving the way for regulatory approval under India's evolving biotech policy framework, news agency PTI said.
The team of researchers led by Dean Faculty of Veterinary Sciences, SKUAST-Kashmir, Riaz Ahmad Shah achieved the feat after a research of around four years. Shah's team had previously cloned India's first Pashmina goat- 'Noori'- in 2012, a milestone that garnered global acclaim.
"This path-breaking development places India on the global map of advanced genome editing technologies and positions SKUAST-Kashmir at the forefront of reproductive biotechnology research," Shah told PTI, adding, it marks a historic milestone in the field of animal biotechnology.
The gene editing was performed using CRISPR-Cas9 technology and adhered to international biosafety protocols.
Shah said the gene-edited lamb has been modified for the 'myostatin' gene - a regulator of muscle growth. 'By disrupting this gene, muscle mass in the animal is enhanced by nearly 30 per cent, a trait naturally absent in Indian sheep breeds but known in select European breeds like the Texel,' he said.
For now this has been done at research level. 'The technique has multiple applications. We can edit the genes responsible for diseases to produce disease-resistant animals. It can also help in the twinning of animals at birth,' Shah told The Indian Express.
Gene editing, also known as genome editing, is a group of technologies that allow scientists to precisely change an organism's DNA. These technologies enable the addition, removal, or alteration of genetic material at specific locations within the genome.
The development comes on the heels of the recent release of India's first gene-edited rice variety, endorsed by Union Ministry for Agriculture, and further cements India's growing prowess in genomic science, Shah said.
"The introduction of this mutation through gene editing, and not through traditional crossbreeding, represents a technological leap akin to the revolution Artificial Intelligence is driving in the 21st century," he said.
SKUAST-Kashmir vice-chancellor Nazir Ahmad Ganai described the achievement as the birth of a new era in livestock genetics in the country.
"This is not just the birth of a lamb, but the birth of a new era in livestock genetics in India. With gene editing, we have the ability to bring precise, beneficial changes without introducing foreign DNA, making the process efficient, safe, and potentially acceptable to both regulators and consumers," he said.
Through gene editing, the researchers targeted a gene in a sheep variety that helps in boosting its muscle weight and gives heavier, almost 30 per cent more weight than normal sheep.
This is not just the birth of a lamb, but the birth of a new era in livestock genetics in India.
"We have got the offspring from the mother, and one with the mutated gene is distinctly heavier than the non-mutated,' the vice-chancellor said adding that the DNA of the mutated lamb, which is now three months old, will be sent to foreign research labs for further verification.

Pune scientist leads global team helping ALS patients regain voice
PUNE A Pune-based scientist is front and centre of a major milestone in neurotechnology – an implant-based brain-computer interface (BCI) that enables an individual with advanced amyotrophic lateral sclerosis (ALS) to speak in real time with natural intonation, and even sing. Pune-based scientist is part of neurotech project team that enables individual with advanced amyotrophic lateral sclerosis (ALS) to speak in real time with natural intonation, and even sing. (HT) Dr Maitreyee Wairagkar – a former student of Jnana Prabodhini (Nigdi) and Fergusson College who completed her Engineering Masters and Ph.D. from the United Kingdom and is now based at UC Davis as 'project scientist' to lead the project since the last three years – has set an example of what Indian girls can achieve provided they get a chance. Dr Wairagkar – working with her team of researchers at UC Davis's Neuroprosthetics Laboratory since the last three years – has led the project from conception to design to execution and developed this 'first-in-world' technology that demonstrates a brain-to-voice neuroprosthesis capable of synthesising speech with less than a 25-millisecond delay, virtually indistinguishable from natural vocal feedback. Dr Wairagkar is the first author on the study published in the scientific journal, 'Nature' on June 12, 2025. Drawing on Dr Wairagkar's expertise, her team has developed algorithms to extract and denoise neural features, train phoneme and pitch decoders, and craft a full end-to-end voice synthesis system. Dr Wairagkar and team have enabled the decoding of fine-grained paralinguistic cues, allowing the user to express not just words but also emotion and melody. The system uses 256 microscale electrodes implanted in the ventral precentral gyrus, which is the part of the brain crucial for speech production. In the course of the study, as the participant attempted to speak, neural signals were decoded in real time into phonemes and paralinguistic features like pitch and emphasis and subsequently transformed into audible speech through a vocoder and speaker system. Importantly, the participant was not only able to communicate new words but also ask questions, shift intonation, and sing simple melodies in a major leap towards expressive, spontaneous communication. About the achievement, Dr Wairagkar said, 'What makes this technology extraordinary is not just that it translates brain activity into speech, but that it does so with the flow and character of natural voice. That expressiveness is what makes real conversation possible, and human.' Dr Wairagkar's contributions allowed the participant to control tone and stress in real time; a feature absent in earlier BCIs that often relied on slow, word-by-word output. Senior researchers at UC Davis, including Dr Sergey Stavisky and neurosurgeon Dr David Brandman, emphasised the emotional and practical impact of the work. 'This is the first time we have been able to restore a participant's own voice in real time, allowing him not only to talk but to sound like himself,' said Dr Stavisky. Dr Brandman—who implanted the arrays under the BrainGate2 clinical trial—highlighted the emotional power of restoring not just speech, but the participant's own voice. Test listeners recognised nearly 60% of the words correctly when BCI-driven voice was used (compared to just 4% intelligibility in natural, dysarthric speech), underscoring dramatic improvements in communication clarity. The neuroprosthesis not only decodes speech at the phoneme level but also captures prosody—how a sentence is said—making it the closest attempt yet at recreating natural, flowing conversation from thought alone. This milestone represents a profound shift in assistive communication for people living with ALS, brainstem strokes, or other forms of locked-in syndrome. It also puts India at the centre of a transformative global scientific collaboration through Dr Wairagkar's involvement. The researchers note that although the findings are promising, brain-to-voice neuroprostheses remain in an early phase. A key limitation is that the research was performed with a single participant with ALS. It will be crucial to replicate these results with more participants, including those who have speech loss from other causes such as stroke. As further trials progress and the technology is refined, experts believe this innovation could redefine how neurotechnology restores voice and identity for millions who are otherwise left voiceless.

Axiom-4 put off again, ISRO decides to recall Group Captains Shukla, Nair
BENGALURU: Two days before the scheduled launch of the much-awaited Axiom-4 (Ax-4) Space Mission on June 22, Axiom Space on Friday announced its indefinite postponement. Axiom Space, which is spearheading the 14-day Ax-4 Space Mission to the International Space Station (ISS) with four astronauts from the US, India, Poland and Hungary, has not given the next launch date. Following this, the Indian Space Research Organisation decided to recall Ax-4 mission pilot Group Captain Shubhanshu Shukla and reserve crew member Group Captain Prasanth Balakrishnan Nair. 'NASA has made the decision to stand down from a launch on Sunday, June 22, and will target a new launch date in the coming days. The space agency (NASA) needs additional time to continue evaluating International Space Station operations after recent repair work in the aft (back) most segment of the orbital laboratory's Zvezda service module. Because of the space station's interconnected and interdependent systems, NASA wants to ensure the station is ready for additional crew members, and the agency is taking the time necessary to review the data,' an Axiom Space statement read. The $64 million space mission is a multi-agency collaboration, involving Axiom Space, ISRO, NASA and European Space Agency (ESA). 'The (Indian) astronauts will be returning. There are many technical issues that need to be addressed before the mission is launched,' said a senior ISRO scientist. Shukla and Nair are among the four Indian astronauts selected for India's first manned space mission, Gaganyaan, scheduled to be launched some time in 2027. ISRO Chairman V Narayanan said the Ax-4 mission delays will have no impact on the Gaganyaan mission, which, he said, is progressing as per schedule.

Nasa spacecraft around the moon photographs the crash site of a Japanese company's lunar lander
This image provided by NASA shows an annotation indicating the impact site for ispace's Resilience lunar lander, seen by the Lunar Reconnaissance Orbiter Camera (Picture credit: AP) CAPE CANAVERAL : A Nasa spacecraft around the moon has photographed the crash site of a Japanese company's lunar lander . Nasa released the pictures Friday, two weeks after ispace 's lander slammed into the moon. The images show a dark smudge where the lander, named Resilience, and its mini rover crashed into Mare Frigoris or Sea of Cold, a volcanic region in the moon's far north. A faint halo around the area was formed by the lunar dirt kicked up by the impact. Nasa's Lunar Reconnaissance Orbiter captured the scene last week. The crash was the second failure in two years for Tokyo-based ispace. Company officials plan to hold a news conference next week to explain what doomed the latest mission, launched from Cape Canaveral in January.
