Nobel Prize 2025: What they are, when will the awards be announced?
Nobel Prize 2025: What they are, when will the awards be announced? The Nobel Prize 2025 officially kicks off with the first award, for physiology or medicine, to be announced on Monday, setting the stage for a week of global anticipation. The full schedule, spanning from October 6 to 13, maps out a rapid succession of announcements: medicine, followed by physics, chemistry, literature, peace, and finally culminating with the economics prize next Monday. Here are the complete details of the schedule - and what to expect from this year's Nobel Prizes. What is the Nobel Prize?

The true extent of cyber attacks on UK business - and the weak spots that allow them to happen
The first day of September should have marked the beginning of one of the busiest periods of the year for Jaguar Land Rover. It was a Monday, and the release of new 75 series number plates was expected to produce a surge in demand from eager car buyers. At factories in Solihull and Halewood, as well as at its engine plant in Wolverhampton, staff were expecting to be working flat out. Instead, when the early shift arrived, they were sent home. The production lines have remained idle ever since.
Evaluating Large Language Models for IUCN Red List Species Information
Large Language Models (LLMs) are rapidly being adopted in conservation to address the biodiversity crisis, yet their reliability for species evaluation is uncertain. This study systematically validates five leading models on 21,955 species across four core IUCN Red List assessment components: taxonomy, conservation status, distribution, and threats. A critical paradox was revealed: models excelled at taxonomic classification (94.9%) but consistently failed at conservation reasoning (27.2% for status assessment). This knowledge-reasoning gap, evident across all models, suggests inherent architectural constraints, not just data limitations. Furthermore, models exhibited systematic biases favoring charismatic vertebrates, potentially amplifying existing conservation inequities. These findings delineate clear boundaries for responsible LLM deployment: they are powerful tools for information retrieval but require human oversight for judgment-based decisions. A hybrid approach is recommended, where LLMs augment expert capacity while human experts retain sole authority over risk assessment and policy.
Geolog-IA: Conversational System for Academic Theses
Pozo, Micaela Fuel, Saltos, Andrea Guatumillo, Llumiquinga, Yeseรฑa Tipan, Aguirre, Kelly Lascano, Jara, Marilyn Castillo, Mejia-Escobar, Christian
This study presents the development of Geolog-IA, a novel conversational system based on artificial intelligence that responds naturally to questions about geology theses from the Central University of Ecuador. Our proposal uses the Llama 3.1 and Gemini 2.5 language models, which are complemented by a Retrieval Augmented Generation (RAG) architecture and an SQLite database. This strategy allows us to overcome problems such as hallucinations and outdated knowledge. The evaluation of Geolog-IA's performance with the BLEU metric reaches an average of 0.87, indicating high consistency and accuracy in the responses generated. The system offers an intuitive, web-based interface that facilitates interaction and information retrieval for directors, teachers, students, and administrative staff at the institution. This tool can be a key support in education, training, and research and establishes a basis for future applications in other disciplines.
How China is challenging Nvidia's AI chip dominance
How China is challenging Nvidia's AI chip dominance The US has dominated the global technology market for decades. But China wants to change that. The world's second largest economy is pouring huge amounts of money into artificial intelligence (AI) and robotics. Crucially, Beijing is also investing heavily to produce the high-end chips that power these cutting-edge technologies. Last month, Jensen Huang - the boss of the global AI chip industry leader, Nvidia - warned that China was just nanoseconds behind the US in chip development.
Five killed across Ukraine in overnight Russian attacks
Can Ukraine restore its pre-war borders? Why are Tomahawk missiles for Ukraine a'red line' for Russia? Is Russia testing NATO with aerial incursions in Europe? Five people have been killed in Ukraine after Russia launched hundreds of drones and missiles across the country overnight, which officials said targeted civilian infrastructure. Ukraine's President Volodymyr Zelenskyy said on Sunday that Russia fired approximately 50 missiles and 500 attack drones.
Poland scrambles jets as Russia strikes western Ukraine
Russia pounded Ukraine with missile and drone attacks overnight on Saturday and into Sunday morning, focusing on the major western city of Lviv. Ukraine's neighbour Poland scrambled fighter jets in order to ensure the safety of Polish airspace, the Polish military confirmed. Allied Nato aircraft were also deployed. Lviv's regional head Maksym Kozytskyi said two people were killed in strikes in the region, and two more injured. Elsewhere, Russia again targeted Ukraine's power plants - and one was struck in an overnight attack on Zaporizhzhia, where the mayor said one person died and more than 73,000 people were without electricity.
Russia-Ukraine war: List of key events, day 1,319
Can Ukraine restore its pre-war borders? Why are Tomahawk missiles for Ukraine a'red line' for Russia? Is Russia testing NATO with aerial incursions in Europe? One person was killed and about 30 others injured after two Russian drones struck trains at a station in Ukraine's northern Sumy region. Ukrainian President Volodymyr Zelenskyy accused Russia of "terrorism", while Foreign Minister Andrii Sybiha said Moscow deliberately targeted civilians during the attack.
13 inspiring photos of thriving deep-sea animals
A recent Schmidt Ocean Institute expedition off the coast of Uruguay discovered at least 30 suspected new species and explored a sunken warship. An octopus moves around deep-sea corals at 1,612 meters (about 5,288 feet) during a remotely operated vehicle, or ROV, dive near the historic HMS'Challenger's' oceanographic station 320, where the country's first coral samples were collected almost 150 years ago. Breakthroughs, discoveries, and DIY tips sent every weekday. An expedition led by a team of scientists from Uruguay discovered that the South American nation's deep-sea coral reefs are thriving and teeming with life. The reefs are primarily home to numerous species that were recently listed as vulnerable to extinction.
