Meta has blocked Brazilian President Luiz Inacio Lula da Silva's Facebook page and his campaign advertisements, according to reports circulating two weeks ahead of Brazil's election. The move, if confirmed, would cut a sitting president off a major campaign channel at a critical moment. Reactions online are focused on the timing and on questions of platform power over political speech during an election period.

A World Health Organization pandemic agreement has been signed by countries, yet it remains in limbo over unresolved details, notably financing and how nations will share vaccines and pathogen data. Questions are being raised about what is holding up its implementation, with observers pointing to political and logistical obstacles ahead of countries actually putting the treaty into effect.

A U.S. appeals court has upheld the government's designation of AI company Anthropic as a supply chain risk, a decision with implications for the Pentagon's ability to work with the firm. The ruling keeps Anthropic subject to restrictions affecting its eligibility for federal contracts and defense-related work, and the case is being closely followed across the AI industry and defense community.

The United States has imposed new sanctions targeting the International Criminal Court, a move analysts warn could undermine European sovereignty. The measures affect the Hague-based court's operations and raise concerns in Europe about external pressure on an international legal institution headquartered on EU soil. Commentators say the sanctions test Europe's ability to defend the independence of international justice against American coercive measures.

ESPN has published grades for the 2026 NBA offseason, evaluating free agency signings and contract extensions across the league. The piece assesses which teams strengthened their rosters and which deals may fall short, offering analysts' verdicts on each major move as the league's offseason activity is judged.

Stephen Curry and Kawhi Leonard have each signed two-year contract extensions, a structure shaped by the NBA's over-38 rule. The rule restricts how teams can pay players who will turn 38 during a contract, effectively capping future salary raises, so stars approaching that age often take shorter deals. Analysts are breaking down how the clause influenced the two veterans' negotiations with the Warriors and Raptors.

The Chicago Bulls have announced the signing of guard Brandon Boston, forward Drew Peterson, and center Orlando Robinson. Peterson and Robinson both played last season with the Charlotte Hornets and Orlando Magic respectively.

A new cryptography paper describes forging 1024-bit RSA signatures in time close to the special number field sieve, a faster attack method previously thought impractical at this key size. The result, published on the IACR eprint archive, suggests 1024-bit RSA keys offer less security margin than assumed, and readers are debating whether older systems still relying on them need urgent upgrades to 2048-bit or larger keys.

The Green Bay Packers are reportedly set to sign guard Laken Tomlinson off the Dallas Cowboys practice squad, adding an experienced offensive lineman to their roster. Tomlinson, a veteran guard with previous starting experience in the NFL, gives Green Bay added depth along the interior line.

Researchers have detected a direct radio signal from a planet outside the solar system for the first time. The detection, reported by media outlets, marks a milestone in the search for planets around other stars, as radio emissions from exoplanets had previously only been theorized. Scientists say such signals could offer a new way to study magnetic fields and habitability of distant worlds.

Researchers at Harvard report detecting a radio signal coming directly from a planet outside our solar system. The finding, covered by Futurism, is drawing attention because radio emissions from an exoplanet could indicate a magnetic field or, more speculatively, a technological source. Scientists caution that natural processes are the more likely explanation, and further observations will be needed to confirm the signal's origin.

An Iranian-linked influence operation has been discovered in Israel in the run-up to elections, according to reporting by The Jerusalem Post.
