A space object crossed the sky over New York in 2024 and landed inside a house located in New Jersey, providing a unique scientific opportunity. Analysis of the recovered fragments revealed traces of saltwater and organic molecules originating from a primitive asteroid.
On July 16, 2024, residents of New York, New Jersey, and other American states spotted a meteor during the day. The passage of the celestial body was marked by a loud noise as it penetrated the atmosphere at approximately 14.4 kilometers per second. Researchers were able to trace its trajectory using cameras from the American Meteor Society, resident reports, and a doorbell camera, indicating that its origin was linked to the asteroid belt.
A forensic examination of the pieces showed that they contained preserved material near the surface of a primary asteroid, where reactions occurred with concentrated saline fluids—a phenomenon unprecedented in this type of protoplanetary world. Due to the rock's fragility, it partially disintegrated during atmospheric entry. After becoming invisible, a local weather radar located a cloud of small debris between Staten Island and New Jersey, with Hillsborough receiving one of the largest recovered portions.
The owner of the hit house noticed a hole in the bedroom ceiling, scattered dark fragments, and a sulfur-like odor. He acted quickly, collecting the material with disposable gloves and aluminum foil, packaging the pieces in glass containers, which kept the sample in exceptional condition for analysis. Scientists classified the material as a carbonaceous chondrite CM1/2, an intermediate category between CM1 and CM2.
The fall in Hillsborough is the second occurrence of this type recorded by science. The findings included small salt-rich fragments, suggesting they came from a surface area of the asteroid where water had evaporated and concentrated minerals. Researchers identified several soluble organic compounds, such as amino acids, along with evidence of water-induced modifications.
The discoveries include the presence of 1.8% carbon by weight in the meteorite, 0.07% nitrogen, organic compounds similar to those found in other primitive meteorites, and signs of chemical interactions influenced by saline fluids. Phil Schmitt-Kopplin, an expert in organic mass spectrometry from the Technical University of Munich, commented that a high proportion of the compounds resulted from organic chemistry interacting with minerals. According to experts, such processes may have helped conserve molecules crucial to the chemistry preceding the emergence of life.
Part of the fragments will be kept at the American Museum of Natural History in New York. Denton Ebel, curator of the institution, expressed enthusiasm about the arrival of such an asteroid sample. This event demonstrates how an accidental impact on a residence can expose details of a distant past, recorded in materials formed in the early stages of the Solar System.
Researchers from Brazil are actively participating in NASA missions, studying Mars, volcanoes on Saturn's moons, and the function of 'mini-brains' on the Space Station. These scientists make a significant contribution to the American space agency's research.
A biologist from Brasília, Alina Martins, became interested in space at around age 14 after watching the film 'Blade Runner' (1982). She was drawn to the final words of the android Roy Batty. This interest led her to co-direct a laboratory conducting advanced research for NASA.
Martins began engaging in space research in 2022 after meeting Allison Muotri, a neurobiologist from San Diego. They collaborated with chemist John Yates from The Scripps Research Institute. Their joint work involved analyzing samples of cellular material sent to the International Space Station (ISS). The study examined how the space environment affects dormant parts of DNA, potentially accelerating the aging of astronauts' neural cells.
Allison Muotri emphasizes that the goal of all their space experiments is to understand the influence of space on the human brain and apply this knowledge to treat neurological diseases on Earth. Among the projects, they study mechanisms of accelerated aging, methods of radiation protection, the search for neuroprotectants, the development of new materials for brain-machine interfaces, and modeling conditions such as Alzheimer's disease, autism, Parkinson's, and dementia.
In 2024, Alina Martins became co-director of the University of California, San Diego (UCSD) laboratory with Muotri. The laboratory was named 'Orion,' which held personal significance for her. Martins, 49, is responsible for onboard experiment technologies and the analysis of mini-brains returning from the ISS, noting that Americans view Brazilians as a missing 'spice' in research.
Of the ten scientists working on space projects, nine were born in Brazil. Luisa Coelho, a biologist from Florianópolis, 27, is one of the younger members of the team. She joined the project seven years ago while pursuing her master's degree at UCSD. Coelho began working with Muotri after seeing his work on simulating Neanderthal characteristics in organoids, which he calls 'mini-brains,' in a television report about him as a professor at the same university. Today, she is a mission specialist focusing on studying the brain's immune systems.
Muotri, 51, moved to the US in 2002 for postdoctoral research. He is known for his pioneering research, including discovering the link between the Zika virus circulating in Brazil and microcephaly in 2016. In 2018, he founded the field of 'neuroarchaeology,' creating Neanderthal mini-brains. His involvement in space research began in 2016 when he detected signs of accelerated aging in human cells in space. Despite warnings he issued to NASA, he decided to fund the sending of a mini-brain experiment into space in 2019, which confirmed his hypothesis. Since then, NASA has paid attention to and funded his work.
Muotri's laboratory is the most Brazilian among research centers working with NASA in the US. However, there is another center closely associated with the presence of Brazilian scientists—the Jet Propulsion Laboratory (JPL) in California, which has been operating since 1989. JPL is a traditional NASA center, established in 1936. In 1991, planetary geologist Rosalina Lopez became a member of the Galileo Project, which studied Jupiter and its moons. She observed the volcanic moon Io from 1996 to 2001, leading to the discovery of 71 active volcanoes, earning her a Guinness record. Afterward, she worked on the Cassini mission to Saturn and continues to study the volcanoes on Titan, the largest moon of the solar system's sixth planet, which are cryovolcanoes.
Scientists such as Ramon De Paula, an engineer who led the Phoenix probe mission to Mars, and Ivair Gontijo, an engineer who participated in the Curiosity mission to Mars, also worked at JPL. Planetologist Nilton Renno from São Paulo began working with probes aimed at Mars in 2007. He led research that resulted in the discovery of liquid water beneath the surface of Mars in 2008.
Google has promoted a name change in its generative artificial intelligence tool, NotebookLM, which has been renamed to Gemini Notebook. This service assists users with study tasks and data structuring.
Currently, the service is used by over 30 million individuals and about 600 thousand organizations. NotebookLM was introduced during the Google I/O 2023 event under the codename Project Tailwind. Despite unexpected success, which led to widespread adoption, the name change was seen as a way to make the designation more accessible, leveraging the recognition of Google's main AI service.
Although the transition is underway, the service may still appear as NotebookLM on the web version, while the applications have already been updated with the new name.
Google clarified that Gemini Notebook will continue to operate as an autonomous product, but now incorporating a new capability. A feature has been activated that allows Gemini Notebook to connect to a secure cloud computing environment for writing and executing code when creating a notebook. This functions as an isolated testing environment, allowing the system to perform complex analyses without exposing confidential data or interfering with other features.
However, this specific advancement is limited to Google AI Ultra subscribers and Workspace corporate clients who have AI Ultra Access or AI Expanded Access subscriptions. Google AI Pro users will gain access to this functionality at a future time.
Gemini Notebook is described as a powerful generative AI service designed to help the user organize, summarize, synthesize, and retrieve specific information, acting as an advanced digital notebook. It is particularly useful for students or professionals dealing with large volumes of information. In addition to processing text, the tool can also handle audio data (such as podcasts) or generate personalized videos.
It is important to note that the service has a free version, but certain advanced functionalities require purchasing paid AI packages offered by Google.
