Elon Musk‘s brain implant startup Neuralink, which was valued at close to $2 billion (roughly Rs. 16,500 crore) in a private fundraising round two years ago, is now worth around $5 billion (roughly Rs. 41,300 crore) based on privately executed stock trades described to Reuters by five sources with knowledge of the matter.

Some purchases by bullish investors boosted the valuation in recent months, ahead of Neuralink’s May 25 announcement that U.S. regulators had approved a human trial on its brain chip, the sources said.

Experts have said it could take several years for Neuralink to secure commercial use clearance. Kip Ludwig, former program director for neural engineering at the U.S. National Institutes of Health (NIH), said he “optimistically” expected Neuralink to take at least 10 more years to commercialize its brain implant. The company also faces other challenges that include federal probes into its handling of animal research.

Following the trial’s approval, however, Neuralink shares were marketed privately to investors in recent days at a $7 billion (roughly Rs. 57,900 crore) valuation, equivalent to $55 (roughly Rs. 4,500) per share, according to an email seen by Reuters. Reuters could not establish whether the seller found buyers for that price. The email cited the U.S. Food and Drug Administration’s (FDA) approval of the clinical trial as grounds for the deal being “sweeter.”

Neuralink executives and Musk did not respond to requests for comment.

Musk has expressed grand ambitions for Neuralink, saying its chip would allow healthy and disabled people alike to pop into neighbourhood facilities for speedy surgical insertions of devices to treat obesity, autism, depression and schizophrenia. He even sees them being used for web-surfing and telepathy. A Neuralink executive recently gave more modest short-term objectives, such as helping paralyzed patients communicate through computerized text without typing.

The stock transactions at a valuation of around $5 billion (roughly Rs. 41,300 crore) have been carried out by shareholders such as employees and the company’s early backers, rather than Neuralink selling new shares to investors. Such so-called secondary trades are an imperfect gauge of a company’s value; their volume is thin and they lack the wider market consensus of a fundraising round or initial public offering (IPO).

Neuralink’s valuation jump in secondary trades is in sharp contrast to other startups. About 85percent of pre-IPO companies are currently valued in secondary trades at an average discount of 47 percent to their last funding round, according to data provider Caplight.

In Neuralink’s last known fundraising in 2021, it raised $205 million (roughly Rs. 1,700 crore) at an approximately $2 billion (roughly Rs. 16,500 crore) valuation, according to data provider Pitchbook.

Many of the recent stock sales have been to relatively small investors, who typically focus more on getting a slice of a company owned by Musk than scrutinizing its valuation. The maximum amount sought for the Neuralink shares marketed for sale at a $7 billion (roughly Rs. 57,900 crore) valuation was just $500,000, according to the email seen by Reuters.

Sim Desai, chief executive of Hiive, an online platform where the shares are traded, said demand for Neuralink stock has been “tremendous.” He pegged the valuation that buyers are willing to pay at around $4.5 billion (roughly Rs. 37,200 crore).

Some biomedical experts are skeptical. Arun Sridhar, a scientist and entrepreneur who specializes in neuromodulation, called Neuralink’s valuation “bonkers” based on how early the brain implant is in its clinical development.

“A study to assess safety and tolerability is in no shape or form valid to justify a $5 billion (roughly Rs. 41,300 crore) valuation,” said Sridhar, who helped launch Galvani Bioelectronics, a developer of implants backed by GSK Plc and Alphabet Inc’s Verily Life Sciences. Galvani is not a competitor of Neuralink because its implants under development will be installed in an artery to the spleen to help treat rheumatoid arthritis, rather than the brain.

Investigations

The FDA initially rejected Neuralink’s request for a human trial last year, citing safety reasons, Reuters has reported. Even after securing approval, the company faces several challenges.

Neuralink has come under scrutiny from U.S. lawmakers after Reuters reported in May that its animal-research board may have violated conflict-of-interest regulations. Neuralink employees who sat on that board, which oversees the welfare of the animals that were being tested, also stood to benefit from the implant’s quick development. Neuralink stock that some of the employees hold has jumped around 150 percent in value in just two years, based on the secondary trades.

The law enforcement arm of the U.S. Department of Agriculture has been investigating Neuralink for potential animal-welfare violations. Neuralink staff told Reuters last year that the company was rushing and botching surgeries on monkeys, pigs and sheep, resulting in far more animal deaths than necessary, as Musk pressured staff to receive FDA approval.

The Department of Transportation is separately probing whether Neuralink illegally transported dangerous pathogens on chips removed from monkey brains without proper containment measures.

Neither Musk nor Neuralink have responded to multiple requests for comment on the probes or the Reuters reports.

Could These Meteorites Be from Mercury? New Research Hints at Rare Discovery

Scientists have observed whether the meteorites can reach Earth from Mercury. Over thousands of meteorites from Mars and the Moon have been observed, but none have been from Mercury, despite it being a nearby rocky planet. A new study revealed Icarus suggests two meteorites, Ksar Ghilane 022 and Northwest Africa 15915, could belong to Mercurian origin. Such a kind of meteorite can offer a realistic opportunity to study the material of the surface of the planet, if the technical challenges and the cost of sending a spacecraft to Mercury are met.

New Meteorite Samples Show Strong Similarities

As per the new studies reported to Physics.org , Meteorite NWA 7325 and aubrites in the past were considered to be possibly from Mercury. However, the mineral composition of their samples has inconsistencies with the known surface data from the Messenger mission of NASA. Aubrites formed on a planet similar in size to Mercury, lacking spectral and chemical similarities, and further weakened as Mercurian fragments.

Ksar Ghilane 022 and NWA 15915, the new samples, share many traits of Mercury crust, with olivine, oldhamite, pyroxene, and minor albitic plagioclase. The oxygen composition of these matched with the aubrites, signalling a similar planetary origin and putting them among strong Mercurian members.

Key Differences Raise Scientific Questions

There are key differences even after that, and the two meteorites contain very little plagioclase than on the Mercury surface, and are about 4,528 million years older than Mercury’s surface material. If they are from Mercury, there is a possibility that they can represent an ancient crust which is no longer visible on the planet.

Future Missions and Scientific Verification

Relating a meteorite to a particular planet is quite difficult without direct samples. BepiColombo missions are orbiting Mercury currently, and can offer valuable insights to confirm meteorites source. Mercurian meteorites can get valuable insights into the formation, composition and history of the planet. There are further findings to be presented at the Meteoritical Society Meeting 2025 in Australia.

Rocket Lab Launches ‘Get the Hawk Outta Here’ Mission with Four Satellites from New Zealand

The “Get the Hawk Outta Here” mission saw Rocket Launch juggle four satellites into orbit around Earth on June 27, marking yet another mission on the start-up’s 2025 calendar. The Electron rocket — loaded with three radio-frequency tracking microsatellites and a technology demonstrating payload — lifted off from Pad-A in Launch Complex 1 in Mahia, New Zealand, at 1:28 p.m. EDT (1728 GMT). The launch is to aid Virginia-based geospatial analytics company Hawkeye 360 with its pursuit to broaden radio-frequency intelligence gathering.

Rocket Lab Launches Cluster 12 RF Satellites for Hawkeye 360, Eyes More Missions in 2025

As per the Rocket Lab’s official mission brief, the three working satellites are designed to help Hawkeye 360 triangulate radio signals across the world. Such spacecraft would fill gaps in coverage and provide radio frequency analytics data in near real time from areas of strategic interest. The fourth payload, Kestrel-0A, is a technology demonstrator meant to test advanced capabilities and future enhancements for the Hawkeye constellation.

Rocket Lab has committed to launching a total of 15 satellites across three missions for Hawkeye 360. This mission is themed “Virginia Is For Launch Lovers” and is Electron’s first mission from U.S. soil following the company’s first launch from Wallops Island in January 2023. This latest mission signifies the 67th overall Electron launch and the ninth of 2025 in a sign of the company’s increasing launch cadence.

All satellites were placed into a polar low Earth orbit at about 320 miles (520 km) altitude, ideal for cross-cutting the Earth and thus ensuring fast revisits and high signal collection. Electron’s payload fairings also did their job, protecting the satellites as they lifted off, then releasing them into orbit with pinpoint accuracy.

In its roadmap, Rocket Lab has at least six additional launches this year, and all eyes are on its upcoming reusable Neutron rocket. The company also operates a suborbital Electron variant, HASTE, which serves as a testbed for hypersonic and defence technologies. The latest launch further solidifies Rocket Lab’s position in the small satellite deployment market.

Astronomers Discover Baby Planets Taking Their First Steps in Nearby Stellar Nursery

Astronomers Discover Baby Planets Taking Their First Steps in Nearby Stellar Nursery

Astronomers may have just caught a glimpse of the early signs of the formation of “baby” solar systems in the hydrocarbon-rich disc around two young stars in a star-forming region near Earth, in a study that could offer fresh insights into how planetary systems are created. From studying 78 protoplanetary disks — or flattened clouds of gas and dust — in the Rho Ophiuchi cloud complex, researchers spotted spiral and ring-like substructures, which are certain signatures that baby planets are in the process of being born.

The disks, around stars a few hundred thousand years old showed unusual characteristics, indicating that planet and star formation are simultaneous processes in very young systems. In comparison, the Sun is a middle-aged 4.6 billion years old.

High-Res ALMA Imaging Reveals Planet Formation Begins Earlier in Young Star Disks Than Expected

As per the research team, the discovery helps bridge a key observational gap between previous ALMA studies—DSHARP, which focused on million-year-old stars, and eDisk, which studied much younger protostars. By targeting stars of intermediate ages and applying PRIISM super-resolution software to archival ALMA data, researchers achieved images three times sharper than standard methods. Their larger sample led to the identification of 27 disks with structures, including 15 never seen before.

The results indicate that substructures such as rings and spirals, believed to be the fingerprints of planet formation, appear much earlier in a planet’s growth process than previously thought, when the disks are still full of gas and dust. During the childhood of young stars forming in collapsed molecular clouds, these disks were born, and in the same way, young planets formed within the lifetimes of these accretion disks, moved, and shaped the objects in the disk.

Most disks observed were about 30 astronomical units wide, roughly 30 times the Earth-Sun distance. The presence of intricate structures in such early systems implies a parallel evolution of infant stars and planets. The research indicates that star and planet creation might be more closely linked than thought.

The research, which was published on an online site for The Publications of the Astronomical Society of Japan, was led by Ayumu Shoshi of Kyushu University. The present results involve only the Ophiuchus regions, but in the future, as more data become available, we will be able to search for similar early co-evolution amongst other stellar nurseries.
