Japan lawmakers to visit China in bid to cool row, but thaw unlikely: experts

A reported trip to China next week by a cross-party group of Japanese lawmakers could carry “pronounced” symbolic weight but is unlikely to herald a thaw in ties between the two neighbours, Chinese experts suggest. For the first time since bilateral relations succumbed to a bitter chill 10 months ago, a delegation of Japan’s parliamentary members will visit Beijing from August 24 to 27, according to reports by multiple Japanese outlets on Wednesday. Those legislators – including some from the...

US designates academic Min Zin as ‘wrongfully detained’ in China

The US State Department said on Thursday that it had determined after a detailed investigation that Min Zin, an American political analyst of Chinese descent detained by Beijing last month, was being improperly held. That formal designation shifts the case from a State Department consular issue to one handled by its presidential office dealing with hostage affairs. Thursday’s terse statement, which said the decision was made by Secretary of State Marco Rubio, adds another irritant to the fraught...

New Peru government vows to apply Hong Kong trade deal, but is silent on mainland China

Peru’s new government has pledged to bring its free-trade agreement with Hong Kong into force this year as part of an effort to position the country as a commercial bridge between South America and the Asia-Pacific, even as its first comprehensive policy programme made no direct mention of mainland China or the Chinese-operated Chancay megaport. Prime Minister Luis Galarreta told lawmakers on Thursday that commercial openness would remain a state policy under Peruvian President Keiko Fujimori’s...

Lula Defends Nuclear Submarine, Says Brazil Cannot Keep Its "Head Bowed" Forever

President Luiz Inácio Lula da Silva (Workers' Party) defended on Wednesday (19) the completion of the Navy's nuclear submarine as a matter of national sovereignty, saying Brazil cannot keep its "head bowed" forever. In a speech during a visit to the Aramar Nuclear Industrial Center in Iperó, São Paulo, he promised to secure the funds "once and for all" to complete the project - a statement made nearly three months after the government cut R$4.4 billion ($849,000) from the Defense Ministry's budget.

Earth’s oldest trees reveal history’s strongest solar storms

Although humanity continuously reckons with many problems here on Earth — war, political turmoil, epidemics and pandemics, all while the energy, climate, and water crises intensify — it’s important to remember just how relentless the Universe can be. While earthquakes, tornadoes, volcanoes, hurricanes and other natural disasters haven’t exactly ceased in the meantime, there’s a completely different looming threat for which we’re completely unprepared: a solar storm . Rather than the more familiar sets of terrestrial events that can endanger us, it’s the space weather generated by the Sun that…

China ha probado durante 5.211 segundos el motor de su nuevo “taxi espacial”. El siguiente paso será llevarlo al espacio

Durante buena parte de la historia espacial, el gran desafío fue conseguir que una nave pudiera abandonar la Tierra y alcanzar la órbita. Pero la industria espacial está entrando en una fase en la que llegar hasta allí ya no es suficiente: también importa qué ocurre después del lanzamiento. A medida que aumentan las constelaciones de satélites y las misiones requieren trayectorias más complejas, gana importancia una idea que hasta hace poco era menos visible para el gran público: vehículos capaces de continuar la misión. China está desarrollando una de esas piezas con Lixun-1, una etapa…

La “primera ciudad aeropuerto” de Latinoamérica comienza a tomar forma: así es el proyecto que quiere cambiar el transporte

Durante mucho tiempo hemos entendido los aeropuertos como lugares de paso: llegamos con una maleta, atravesamos controles, esperamos una llamada de embarque y desaparecemos por una puerta que nos conecta con otro punto del mapa. Pero esa relación empieza a cambiar en algunos grandes proyectos de infraestructura, donde la pregunta ya no es solo cuántos pasajeros puede mover una terminal, sino qué más puede ocurrir alrededor de ella. El Aeropuerto Internacional Jorge Chávez de Lima quiere explorar precisamente esa idea: convertir una infraestructura pensada para viajar en un espacio donde…

Debates over AI consciousness are a trap

“Runaway” AI, “rogue” agents, and “autonomous” actors—the current rhetoric would have you believe that AI agents are not only awake and aware, but angry at their creators. Prominent tech leaders such as Demis Hassabis, Dario Amodei, and Sam Altman push for regulation of these seemingly “superhuman” systems, while a separate faction, led by policy organizations…

Schizophrenia’s lost brain connections follow a surprising pattern

Specialized brain scans reveal that schizophrenia is linked to widespread loss of the synapses that connect brain cells, with the left side of the brain hit especially hard. The damage follows a surprisingly organized pattern tied to the brain’s chemistry and wiring. Researchers also identified a left frontal region that may serve as a starting point for the loss.
