Scientists believe the first recognized interstellar object, IM1, was protected by a thick film of shock-resisting steel when it crossed through interstellar medium. Metal pearls from the meteor have been found, and are being retrieved for analysis. Avi Loeb, director of Harvard University's Black Hole Initiative, is the author of two books related to extraterrestrial life and interstellar.

A researcher discovered non-thermal emissions from the classical nova V1674 Herculis, which challenges the current views of classical novae as simple heat-induced explosions. The data from the Very Long Baseline Array (VLBA) reveals more complexity in the behavior of classical novae. Montana Williams is leading an investigation into the VLBA properties of this nova and is hoping to determine if the steep spectrum in the radio synchrotron is the signature of a neutron star or a pulsar powering the emission.

TradingThomas (52k followers) has reported Nancy Pelosi bought PUTS against Nvidia, suggesting she had insider knowledge of the US government possibly imposing a stronger restriction against Nvidia and AMD chip sales to China. If true, the US government has a history of taking a tough stance against insider trading, with potential punishments ranging from fines, imprisonment and permanent ban from office positions.

As robots continue to become more integrated into our lives, a recent review of research on robot rights proposes a Confucian-inspired approach to assigning role obligations to robots instead of granting rights. Although rights often lead to conflict, role obligations encourages teamwork, which ultimately leads to harmony. However, ultimately there is much to consider when it comes to granting robots moral and legal status.

Recent progress in AI has been impressive and OpenAI's flagship GPT-4 may soon be one-upped by Google Deepmind's new algorithm 'Gemini'. The new algorithm will combine the strengths of AlphaGo with the capabilities of GPT-4 and will be capable of fusion between multiple types of data and reinforcement learning. It will also be designed for API integrations and using Google's data sets to enable the algorithm to achieve wild results. It remains to be seen what Google's end-goal with Gemini is.

The research team led by Prof. Wei Chen has published new research on integrating Visualization and Artificial Intelligence (AI) for data analysis. This new method, called VIS+AI, offers three different integration levels of visualization and AI. The VIS+AI framework is used to open up the barrier-free communication between human intelligence and AI intelligence in visual analysis.

Scientists have calculated a 7% probability of a neighboring planet within our solar system in the distant Oort cloud. Drawing from Percival Lowell's 1906 pursuit of a 'Planet X' beyond Neptune's domain, simulations of the unstable celestial mechanics of the early solar system propose a potential icy giant planet, much farther away than Lowell's proposed Planet Nine. Such a planet is likely to be faint with an elongated orbit similar to a comet's ellipse. It is hypothesized that multiple celestial bodies could be present in the Oort cloud, emphasizing the vast untapped potential for discovery within our own solar system.

MIT engineers have developed a superabsorbent material from hydrogel infused with lithium chloride which can absorb moisture from the air, even in dry conditions. The material could be used as a passive water harvester to collect drinking water in desert and drought-prone areas.

The 2023 Georgia Peach harvest is looking to be the worst in recent years due to a mild winter and late spring frost, with estimated losses up to 90%. Georgia peaches have always been a surprisingly fragile commercial crop, requiring intricate pest control and careful handling. As a cultural icon, Georgia peaches have been heralded since the 16th century, and overtime become deeply intertwined with the unpredictable nature of the environment.

The Yale School of Public Health conducted a study finding that elderly individuals suffering from mild cognitive impairment (MCI), a prevalent form of memory loss, had a 30% higher chance of recovering their normal cognitive abilities if they held positive attitudes about aging from their cultural background, in contrast to those with negative aging attitudes. The new study is the first to find evidence that this culture-based factor — positive age beliefs — contributes to MCI recovery.

Asst. Prof. Sudipta Chattopadhyay and fellow SUTD researchers, in their study "Towards backdoor attacks and defense in robust machine learning models", published in Computers & Security, studied how to inject and defend against backdoor attacks for robust models in a certain ML component called image classifiers that are trained using the state-of-the-art projected gradient descent (PGD) method. They found that robust models are highly susceptible to backdoor attacks (67.8% success rate) and developed AEGIS, the very first backdoor detection technique for PGD-trained robust models, with an average detection rate of 93.7%.

Researchers from Tohoku University have developed machine learning based on reservoir computing to analyze the computational capabilities of an "artificially cultured brain" composed of rat cortical neurons. Their findings reveal that the artificial cultured brain can possess a short-term memory of several hundred milliseconds, filter information to improve reservoir computing performance, and classify time-series data, such as spoken digits.

The NASA Perseverance Science Team working on Mars have been attempting to obtain a sample from a crumbly conglomerate rock unit in Jezero crater. The rock is unique in that the clasts come from distant locations, giving great insight into Martian history. After three attempts, the team successfully obtained a sample that will be analysed for elements and minerals that hold the key to understanding the Martian environment – past and present.

Modified microbes could be used as potential treatments to aid gut health and reduce inflammation in a variety of diseases. Brad Ringeisen and Justin Sonnenburg are both exploring ways to use modified microbes to engineer a healthier microbiome for humans. This could potentially lead to treatments that would work the same way for people with different microbiomes.

This paper discusses an adaptive spatiotemporal attention neural network (ASTANN) for cross-database micro-expression recognition (CDMER) tasks. The proposed model uses a deep neural network with a spatiotemporal attention mechanism, preprocessing databases by extracting optical flow information, and a simple yet effective loss function. The main advantage of this model is that it can focus on the subtle features of micro-expressions for CDMER tasks.

A study by the University of Rhode Island has shown that the evolutionary changes in lizards can result in significant impact on vegetation growth and spider populations on small islands in the Bahamas. This is one of the first times, the researchers say, that such dramatic evolution-to-environmental effects have been documented. The conclusion of the study has profound implications for restoration of habitats and preservation of animal populations.

The US Department of Agriculture has ruled that lab-grown cultured chicken is safe and legal to sell in the US, making for one of the biggest milestones in the industry. Two companies, Upside Foods and Good Meat, have already received FDA approval and plan to launch their products at upscale restaurants. However, many Americans remain skeptical of lab-grown meat due to it's high costs, scalability issues, and biological limitations.

A recent study found that people were 3% less likely to spot false tweets generated by AI than those written by humans. OpenAI's large language model GPT-3 is powerful and can generate incorrect text that appears convincing. AI-text-detection tools are still in its early stages of development and further research is needed to determine the impact of AI-generated inauthentic content.
