A new methodology has been created by scientists that allows estimating the intensity of the next solar cycle up to seven years in advance. This technique works by identifying a specific moment when extreme solar activity ceases, using this data to project the subsequent peak.
The research demonstrates that the Sun does not decrease its activity progressively. The researchers identified a transition point where the most intense space weather is abruptly interrupted during each solar cycle.
This discovery was made by Sandra Chapman, Professor of Physics and director of the Centre for Fusion, Space and Astrophysics at the University of Warwick. She explained that the most extreme space weather does not end smoothly, but rather quite suddenly at a defined point in each solar cycle.
The team observed that the amount of sunspots at this transition point can serve as an indicator of the strength of the next activity phase. Initial projections for Solar Cycle 26 point to moderate strength, with estimates of between 100 and 120 sunspots at the peak, showing intensity equal to or lower than that of Solar Cycle 25.
The Sun operates in approximate 11-year cycles, characterized by variations in the magnetic field and sunspot count. Such phenomena can generate coronal mass ejections and explosions, constituting space weather. This weather can affect crucial systems on Earth, such as power grids, navigation, satellites, and communications.
The method used is based on the concept of a 'solar clock,' previously conceived by Chapman to organize the irregular cycles of the star. Analyzing sunspots at the transition point establishes a direct link to the peak of the following cycle, allowing for early predictions, unlike methods that rely only on the period of least activity.
Currently, they are about two years away from the shutdown point of Solar Cycle 25. When this point is reached, observations will allow for a much more accurate prediction of Solar Cycle 26. In addition to improving forecasts, the study also helps scientists understand the functioning of the solar dynamo, the mechanism responsible for creating the star's magnetic field.

She proposed that the two countries establish a joint scientific working group.
According to Kamar, recent achievements of Iran on the international stage serve as a source of inspiration for many countries, including Pakistan. The official representative emphasized the emotional, spiritual, historical, and cultural ties between the two states, stating that Pakistan will support Iran's initiatives and actions, and that relations between Tehran and Islamabad will remain strong and stable based on these commonalities. She added that both sides need to develop cooperation to fully utilize each other's potential.
Wajeeha Kamar noted that deep linguistic, religious, and civilizational ties contribute to the development of interaction, and Pakistan can benefit from Iran's valuable experience in areas such as skills training, agriculture, construction, and manufacturing. For his part, Simai-Sarraf stated that the current scientific, academic, and technological cooperation between Iran and Pakistan does not meet the potential of both sides. He also highlighted the need to establish departments for Persian and Urdu languages in the respective countries.
The Minister of Science announced the readiness of the Sistan-Baluchistan University to accept Pakistani students, emphasizing the university's scientific opportunities. Furthermore, on the sidelines of the 43rd Session of the UNESCO General Conference in Samarkand, Uzbekistan, from October 30 to November 13, 2024, Simai-Sarraf met with Wajeeha Kamar. During this meeting, the parties emphasized cultural and civilizational bonds and called for the expansion of scientific, academic, and educational cooperation. The Pakistani minister highly praised Iran's achievements in technology and digital transformation, while Simai-Sarraf expressed the country's readiness to share scientific and technological experience with Pakistan.

Meta has initiated a program in Brazil aimed at developers, students, researchers, and professionals interested in creating new applications for its smart glasses. This initiative seeks to expand the range of functionalities available on the device.
In collaboration with CEIA-UFG, the program offers training, a hackathon, and cash prizes. Furthermore, it fosters a crucial debate accompanying the launch of these glasses: the issue of user privacy.
After reaching millions of users, Meta's smart glasses are entering a new phase where the company aims to increase the number of compatible applications, betting on Brazilian talent to accelerate this process. The AI Glasses Brazil Program, developed in partnership with the Center of Excellence in Artificial Intelligence of the Federal University of Goiás (CEIA-UFG), invites participants to design new applications using features such as camera, audio, voice commands, and artificial intelligence.
Proposals can cover various areas, including health, education, accessibility, tourism, productivity, and creativity. The program is structured in several phases: online technical training; a virtual idea marathon with mentoring and lectures; an in-person hackathon held at Meta's headquarters in São Paulo for selected teams; and finally, cash prizes and the delivery of smart glasses to the winners.
Registration remains open until July 30th. Teams advancing to the in-person phase will have their transportation and accommodation costs covered by the company. The main winners will receive US$3,000 (approximately R$15,000), while second and third place winners will be awarded US$2,000 (about R$10,000) and US$1,000 (about R$5,000), respectively. All finalists will also receive a pair of Meta glasses.
The device's capabilities go beyond simple photography and video recording. For example, it is possible to send images via WhatsApp using only voice commands or view data directly on the lenses and perform actions through gestures. Despite these functionalities, the application offering is still limited, motivating Meta to provide a development kit to attract new solution creators.
With the increase in functions, concerns grow. A notable example was the development by Harvard students of a facial recognition system for Meta glasses, capable of displaying internet information about filmed people. Additionally, there have been reports of the equipment being used by United States immigration agents during operations, intensifying the debate on surveillance.
Another sensitive aspect relates to media storage; photos and videos are kept in Meta's cloud and can be used to train its AI models, including with the help of human reviewers. The company also had to respond to attempts by users to disable the recording LED. Currently, the glasses stop recording if this indicator is damaged. Although the program opens doors for innovation, it is expected that these new applications will evolve alongside mechanisms that reinforce privacy protection.
