Billionaire entrepreneur Elon Musk expects his brain-chip startup Neuralink to start its first human trial this year, he said on Friday in France.

Speaking at the VivaTech event in Paris, co-founder Musk said Neuralink plans to implant a tetraplegic or paraplegic patient during a webcast monitored by Reuters. While Musk didn’t specify how many patients his company would implant or for how long, “it’s looking like the first case will be later this year,” said Musk, who is also CEO of electric carmaker Tesla, social media platform Twitter and the SpaceX rocket launch company.

Last month, Neuralink said it received US Food and Drug Administration (FDA) clearance for its first-in-human clinical trial, a critical milestone for the startup as it faces US probes over its handling of animal experiments. The FDA acknowledged in an earlier statement to Reuters that the agency cleared Neuralink to use its brain implant and surgical robot for trials but declined to provide more details.

If Neuralink can prove its device is safe in humans, it would still take several years, potentially more than a decade, for the start-up to secure commercial use clearance, experts earlier told Reuters. The company is also competing with other neurotech companies which have already implanted their devices in people.

Musk has missed timelines on his public pronouncements about Neuralink before, however. On at least four occasions since 2019, Musk predicted that Neuralink would soon start human trials.

The company, founded in 2016, first sought permission from the FDA in early 2022, and the agency rejected the application, citing dozens of safety concerns, Reuters has reported. Some of the issues involved the lithium battery of the device, the possibility of the implant’s wires migrating within the brain, and the challenge of safely extracting the device without damaging brain tissue.

Neuralink also faces federal scrutiny following Reuters reports about its animal experiments.

Last year, Neuralink employees told Reuters the company was rushing and botching surgeries on monkeys, pigs and sheep, resulting in more animal deaths than necessary, as Musk pressured staff to receive FDA approval. The animal experiments produced data intended to support the company’s application for human trials, the sources said.

In one instance in 2021, the company implanted 25 out of 60 pigs with the wrong-sized devices. All the pigs were subsequently killed – an error that employees said could have been easily avoided with more preparation.

In May, US lawmakers urged regulators to investigate whether the makeup of Neuralink’s panel overseeing animal testing contributed to botched and rushed experiments after Reuters reported on potential financial conflicts on the board.

The Department of Transportation is separately probing whether Neuralink illegally transported dangerous pathogens on chips removed from monkey brains without proper containment measures. An agency spokesperson said on Friday the investigation is ongoing.

Neuralink has also been under investigation by the US Department of Agriculture’s Office of Inspector General for potential animal-welfare violations. This probe has been looking at the USDA’s oversight of Neuralink. An agency spokesperson didn’t immediately respond to a comment request.

Meanwhile, the company’s valuation has shot up in recent months. The start-up was valued at close to $2 billion (roughly Rs. 16,382 crore) in a private fundraising round two years ago and is now worth around $5 billion (roughly Rs. 40,955 crore) based on privately executed stock trades, Reuters reported this month. Neuralink employees who sat on the company’s animal board, which has come under federal scrutiny for potential financial conflicts, stood to benefit from the implant’s quick development. Neuralink stock that some of the employees hold has jumped around 150% in value in just two years, based on the secondary trades, Reuters reported.

Iran’s Folded Rocks Reveal Ancient Tectonic Power at Asia-Europe Boundary

Iran’s Folded Rocks Reveal Ancient Tectonic Power at Asia-Europe Boundary

The deformed rocks of Iran are formed due to strong mountain ridges and valleys in the Greater Caucasus mountain range, southwest of the Caspian Sea. Between 10 million and 50 million years ago, its growth was marked by sedimentary layers crushed during the first impact between the Arabian and Eurasian tectonic plates. The vividly coloured rocks produced by the sedimentary layers gathered over millennia range in tone from terracotta to greenish to bluish. Using satellite pictures, NASA’s Jet Propulsion Laboratory and Earth Observatory have shown how the landscape tended to cluster over time.

One image depicts the different strata layers, vegetation, and the Zanjan-Tabriz freeway linking Tehran and Poznan. Interestingly, another image is of the Qezel Ozan River, which provides agricultural water in the region. The region is still converging, and fresh research suggests that a slab of oceanic crust is being shredded beneath Iraq and Iran.

Iran’s Folded Rocks Expose Arabia-Eurasia Tectonic Collision

According to reported NASA experts, a tectonic clash between the continents — known as Eurasia and Arabia — crunched these vividly hued strata of rock into massive folds. Located southwest of the Caspian Sea, Iran’s folded rocks are mountain ridges and valleys from the Greater Caucasus mountain chain. The disrupted rocks are made of sedimentary layers that were tilted and folded after the first collision between the Arabian and Eurasian tectonic plates, which is estimated to have occurred 10 to 50 million years ago.

Under Iraq and Iran, some of the oceanic crust between the Arabian and Eurasian plates is breaking apart, according to current research, which results in an anomalous silt accumulation at the surface. The complexity of the Earth’s surface and the Qezel Ozan River, combined with the Neotethys oceanic plate pulling the area down, account for this.

Astronomers Discover Potential ‘Dark Galaxy’ Near the Milky Way

Astronomers might have discovered a dark galaxy, primarily made up of dark matter, in the local universe. Dark galaxies are theoretical starless systems that could provide valuable insight for galaxy formation models. The candidate was in a massive, rapidly moving gas cloud, first discovered in the 1960s. At high resolution, the methyl formate cloud appeared to be a tight knot of gas, potentially forming a dark galaxy. But not all astronomers are convinced. It’s more likely to be a regular gas cloud at the edge of the Milky Way, says the astronomer Tobias Westmeier.

The study was published in Science Adviser. It reveals that since the early 2000s, a few possible dark galaxies have been discovered close to the Milky Way. However, multiple studies have suggested that these alleged dark galaxies were misclassified. The study further highlights that the hypothetical dark galaxy evolved this way after a collision with cosmic gas close to our galaxy. Finding dark galaxies could enable better computer simulations and provide fresh insight into galaxy development.

Astronomers Discover Dark Galaxy Candidate Near Milky Way

According to the report, a hypothetical dark galaxy was revealed amid the field of dark matter in the early eras of the history of the universe. Better knowledge of the development of black galaxies, systems devoid of stars, is what astronomers aim for. First spotted half a century ago, a massive, fast-moving gas cloud showed new promise when scientists detected it. High-resolution cloud observations revealed a tiny gas cluster possibly matching a dark galaxy. Jin-Long Xu from the Chinese Academy of Sciences in Beijing told Science News that the finding marks the first of a potential black galaxy in the nearby universe.

Still, not all scientists agree with the dark galaxy designation of the clump. The report further notes that Westmeier thinks the object is most likely a regular gas cloud at the Milky Way’s edge. The idea dates back to identifying some purported black galaxies in orbit as far back as the early 2000s.

The latest discoveries came from observations with three radio telescopes, including high-resolution photos from the Five-Hundred-meter Aperture Spherical Telescope (FAST) in southern China. In much of the cluster, the scientists shadowed the velocity and direction of hydrogen gas and then deduced distance, which they found to be 900,000 light-years from Earth.

NASA Scientists Study Crystal Formation in Space For Future Applications

NASA scientists have been studying crystals to optimise the process of crystallisation for decades. Various researchers have conducted research on crystals within the first quarter of the year, the latest being protein crystallisation in microgravity. Alexandra Ros from Arizona State University led the research by launching a protein crystallisation test in the International Space Station (ISS). The experiments are meant to determine the growth of protein crystals in space using newly developed microfluid devices. The research agenda is to examine whether space-grown crystals can achieve better quality than those formed on Earth.

What is Crystallisation, & How Does It Impact Our Lives?

It is the process of freezing of liquid or molten materials in the form of highly organised molecules called crystals. These crystals can be a blend of different types of materials. This world consists of crystal examples everywhere. It would be wrong to say that we don’t live in a world of crystals.

Be it a coffee mug, cellphone or silicon that is used to form the brains of electronics and used in memory chips, everything is a result of crystallisation. Other types of semiconductor crystals are used as detectors for different radiations, such as gamma rays, infrared rays, etc. Lasers used in scanning the product are made of optical crystals. Turbine blades are an example of metal crystals used in the jet engine.

Why and How NASA Studies Crystals?

The scientists studied the growth of zinc selenide crystals in space, with the crystals on Earth, explained NASA. The result from the observations marked the way for the improvement of the operations of infrared wavelength in the high powered lasers. The research findings provide an insight into the strong influence of gravity on the electrical, optical and structural characteristics of the crystals.

Researchers have optimised the crystal usage for several years to study the types of crystals for growing in space.

The crystals grown on Earth have defects such as little cracks; these cracks can damage the properties of the crystals. This marks a strong reason why scientists want to study crystals in space, thus getting a complete microgravitational environment where they can grow better. Convection produced due to the presence of the gravitational force degrades the quality of crystals.

However, this convection is not seen in the environment of microgravity, helping in the better quality crystals. The ISS is now converted to a complete lab for the study of the formation of crystals, which can be further applied in technology and medicine.
