Astronomers discover Earth-like exoplanets common across the cosmos: Study
Washington DC [US], April 27 (ANI): Astronomers have discovered that super-Earth exoplanets are more common across the universe than previously thought.
Still, researchers estimated that for every three stars, there should be at least one super-Earth present with a Jupiter-like orbital period, suggesting these massive worlds are extremely prevalent across the universe.
Using the Korea Microlensing Telescope Network (KMTNet), an international team of researchers has discovered that super-Earth exoplanets are more common across the universe than previously thought, according to a new study.
By studying light anomalies made by the newly found planet's host star and combining their results with a larger sample from a KMTNet microlensing survey, the team found that super-Earths can exist as far from their host star as our gas giants are from the sun, said Andrew Gould, co-author of the study and professor emeritus of astronomy at The Ohio State University.
'Scientists knew there were more small planets than big planets, but in this study, we were able to show that within this overall pattern, there are excesses and deficits,' he said. 'It's very interesting.'
While it can be relatively easy to locate worlds that orbit close to their star, planets with wider paths can be difficult to detect.
Still, researchers further estimated that for every three stars, there should be at least one super-Earth present with a Jupiter-like orbital period, suggesting these massive worlds are extremely prevalent across the universe, said Gould, whose early theoretical research helped develop the field of planetary microlensing.
The findings in this study were made via microlensing, an observational effect that occurs when the presence of mass warps the fabric of space-time to a detectable degree.
When a foreground object, such as a star or planet, passes between an observer and a more distant star, light is curved from the source, causing an apparent increase in the object's brightness that can last anywhere from a few hours to several months. (ANI)

Radioactive horns: South Africa's bold approach to rhino conservation
In a world-first effort to combat the ruthless poaching of rhinos, scientists in South Africa have developed a groundbreaking method: injecting rhino horns with radioactive material. The initiative, known as the Rhisotope Project, is the brainchild of researchers from the University of the Witwatersrand (Wits University) and marks a bold, science-driven attempt to save one of Africa's most iconic animals. South Africa is home to the largest population of rhinos in the world—particularly white rhinos and the critically endangered black rhinos. Yet, this very distinction has turned the country into a poaching hotspot. According to conservation charity Save the Rhino , over 400 rhinos have been poached in South Africa every year since 2021, driven by illegal trade networks that stretch from African parks to Asian markets. Read more: After humans, this mammal rules the Earth, and 5 countries with its thriving population (no, not cows!) Rhino horns are highly sought after in parts of Asia, where they are believed to have medicinal properties and are also viewed as luxury status symbols. The lucrative black market has made it difficult for governments and conservationists to keep pace. A radioactive breakthrough Enter the Rhisotope Project, a six-year research effort that cost roughly £220,000 ($290,000) and involved collaboration with the International Atomic Energy Agency (IAEA). The method involves injecting a tiny amount of radioactive isotope into a rhino's horn, a process that has been rigorously tested and deemed completely safe for the animals. Wits University professor James Larkin, one of the key figures behind the project, told the BBC that the innovation shifts the approach from reactive to proactive. 'At least one animal a day is still being poached,' he said. 'This is a significant tool to help reduce the numbers of poaching.' The idea is not to harm anyone who touches the horn but to make the horn detectable by radiation monitors at ports, airports, and border crossings. Customs officers, who already use radiation detectors for other security purposes, could easily identify smuggled rhino horns—even those hidden inside massive 40-foot shipping containers. Pilot study The initial pilot involved 20 rhinos, all of whom responded well to the treatment. Larkin confirmed the material was 'completely safe' and did not harm the animals. The team's success in proving that the radioactive horns can be tracked through international freight systems marks a pivotal moment in the fight against wildlife trafficking. Jessica Babich, head of the Rhisotope Project, emphasized the scale of their ambition: 'Our goal is to deploy the Rhisotope technology at scale to help protect one of Africa's most iconic and threatened species. By doing so, we safeguard not just rhinos but a vital part of our natural heritage.' Read more: 5 snake parks in India that are absolutely fang-tastic and what makes them special Conservationist Jamie Joseph, director of Saving the Wild , called the project 'innovative and much needed.' She noted that while this solution isn't the 'endgame,' it can still disrupt smuggling networks and help experts better understand trafficking routes through hard data. 'It will certainly help disrupt the flow of horns leaving the country and help experts better map out the illegal channels by providing reliable data,' she added. Despite its promise, the Rhisotope Project is not a silver bullet. Activists and scientists alike stress the need for stronger laws, enforcement, and political will. Without these structural changes, even the most advanced technologies may only offer short-term deterrence. Still, the Rhisotope Project represents a rare intersection of nuclear science, conservation, and real-world impact—an example of how innovation can step into spaces where policy and enforcement have lagged. As poachers use more sophisticated tools, so tools used to fight them are also being enhanced.

India's semiconductor mission paves way for digital sovereignty: Experts
Academy Empower your mind, elevate your skills India's semiconductor mission paves way for digital sovereignty and will take the country towards self-sufficiency in chips that have use in a wide array of applications, including CCTV cameras, mobile networks, satellites, cars, and smart devices, experts have said that the central government's initiative lays the groundwork for India to become self-reliant across the entire digital technology stack -- from chip manufacturing to artificial intelligence (AI) and cloud applications. All mission-critical digital infrastructure, whether related to artificial intelligence or cloud computing -- fundamentally depends on semiconductor chips."When you are talking about a completely digital sovereignty, it starts at the chip level. Whether it is a complete AI stack or a complete cloud stack on which any mission-critical applications of government or enterprises run, it always starts from the ground level, which is the chip. From chip level, we end up making equipment," Sunil Gupta, Chair, ASSOCHAM National Council on Datacenter, told ANI on the sidelines of an event 'Sovereign Tech for India's Digital Transformation'. The event was organised by ASSOCHAM."Chips form the base, leading to the development of equipment, operating systems, datasets, models, and ultimately, applications. You start making operating systems, then you run in case of AI examples. You have data sets and then you have models and then you have applications. The government understands this whole stack, which needs to be completely owned by India. At the chip level, India has created a semiconductor mission so that India can design, fabricate, assemble and package its own chips in India itself," Gupta told India Semiconductor Mission (ISM) is aimed at ensuring full ownership of this stack. The mission aims to enable domestic capabilities in chip design, fabrication, assembly, and packaging."The semiconductor mission and the government's emphasis on it is a step in the very right direction. It is at the route of becoming a sovereign nation in terms of digital infrastructure," Gupta said."Starting has been done maybe with chips of 28 nanometers, but I am very sure once this mission starts, we will start manufacturing the most high-end two and three-nanometre chips also. As the Minister of IT also announced that within five years India can also expect its indigenous GPU, which is real sovereignty at the grassroots you are not dependent on a chip which is designed in the US and manufactured in Taiwan. India will be able to design and manufacture chips in India itself," he also spoke about India's efforts to widen its sources of rare earth metals amid export curbs by China."Prime Minister visited countries in Latin America and Africa recently.... India will have to be self-dependent on rare earth metals as these are used in manufacturing electronics products. This is another aspect on which the government is very serious about," he Pillai, founding member of Bharath Cloud, emphasised the significance of Digital India."It is an economic and security story and having everything in house is very important. Having everything on our own soil and working on our own terms is extremely important for us to grow and innovate. India is focused in the area," she Programme for Development of Semiconductors and Display Manufacturing Ecosystem in India was notified in December 2021 with a total outlay of Rs. 76,000 Union Cabinet had in May this year approved establishment of one more semiconductor unit under India Semiconductor semiconductor units are in advanced stages of construction.
