We hadn’t seen a total solar eclipse on the Iberian Peninsula since 1912, and this Wednesday, just before sunset, the celestial bodies aligned once more. That perfect cosmic dance between the Sun, the Moon and the Earth could be seen from numerous regions across Spain. Among the millions of people who observed the phenomenon in Spain, eclipse experts share their impressions with SMC Spain.

A study published in Science Advances has shown that areas affected by extreme wildfires – characterised by rapid spread and great difficulty in extinguishing them – have lower tree cover and reduced resilience compared to less intense fires, which may lead to long-term changes in vegetation. The team analysed 32.1 million hectares of coniferous forest in Canada and the western United States that were affected by fires between 2012 and 2023. Of this area, more than a third was burnt by extreme fires. In these cases, they observed that the faster the fire front advances, the greater the size and severity of the fire and the greater the distance from seed sources for the surviving trees, paving the way for long-term changes in vegetation.

Next Monday, 17 August, COP17 on desertification gets underway in Ulaanbaatar (Mongolia). This is the first of three environmental summits to be held this year. The next event will be in Yerevan (Armenia), where the COP17 on biodiversity will be held from 19 to 30 October, and the year will conclude with the COP31 on climate change, which will take place in Antalya (Turkey) from 9 to 20 November and will be co-chaired by Australia. Why has there been no proposal for a single summit encompassing all three? Would a climate summit held every two years, like those on biodiversity and desertification, be more appropriate? With the United States out of the picture, who is leading them? To answer these and other questions, SMC Spain organised a briefing session with experts who have extensive experience of this type of summit.

A team of researchers has designed complete and functional genomes for bacteriophages — viruses that feed on bacteria — from scratch using generative artificial intelligence (AI), and has tested them against bacteria that had developed resistance to this type of virus. The study, published in the journal Science, represents a step forward towards generative systems capable of designing complete biological systems. The authors also state that it raises important questions regarding biosafety and biosecurity.

OpenAI has stated in a press release that the internal version of its Astra AI model has found solutions to ten research problems in mathematics and computing, in areas such as geometry, group theory, operator algebras, quantum complexity, cryptography and combinatorics, amongst others. According to the company, the total number of tokens — basic units of information — required to solve these problems would cost around $2,000. OpenAI expresses “deep respect and understanding” for those concerned about the impact of AI on these disciplines, including the signatories of the Leiden Declaration on AI and Mathematics; and states that the attribution of results must honestly reflect how each one was obtained, whilst encouraging the mathematical community to review them. The company is publishing these results openly in a paper, accompanied by the model’s account of its reasoning process.

There are just a few days to go until 12 August, when we’ll be able to enjoy the first of the three eclipses we’ll see in Spain. This is a total solar eclipse — the Moon will completely cover the Sun’s disc — something not seen on the Iberian Peninsula since 1912. Experts from different regions of Spain with extensive experience in observing eclipses offer their recommendations. Choosing the right viewing spot, using approved eclipse glasses, coping with the heat and respecting the natural environment are key to observing the eclipse safely and enjoying the experience.

Human-induced climate change has made the ‘extreme’ weather conditions that fuelled the recent wildfires at least twice as likely in France and 20 times as likely in Spain, according to a new analysis by World Weather Attribution (WWA). The team analysed historical weather observations and used the Daily Severity Index (DSR), which incorporates heat, drought and wind conditions and reflects the difficulty of extinguishing a fire. The researchers examined the seven-day period with the highest DSR in south-western France and central Spain, where the fires occurred, and compared it with simulations of a pre-industrial climate. According to the study, under current climate conditions, events of this intensity are projected to occur once every 20 years in south-western France and once every six years in central Spain.

The fire in Ávila, which merged with the one in the south-western mountains of Madrid last Saturday and spread to the province of Toledo, remains unstabilised, although it is under control in some areas. Wind gusts of up to 30 km/h will complicate fire-fighting efforts on Monday, according to the Madrid 112 Safety and Emergency Agency. The fire in Ávila is now the largest in Spain’s recent history. Meanwhile, the fire that broke out on Saturday in La Vall d’Uixó (Castellón), which has spread into the Sierra de Espadán Natural Park, has not yet been stabilised either. In total, around 100,000 people have been evacuated or are under lockdown across all the fire fronts.

In 2025, a six-year-old Chinese girl named Mei (not her real name) became the first person in the world to undergo gene-editing therapy targeting the brain. She had a developmental delay associated with a rare genetic syndrome, Snijders-Blok-Campeau syndrome. According to Science, her parents had raised $860,000 to partially fund the treatment at Xinhua Hospital in Shanghai (China), led by Zilong Qiu, one of the neuroscientists competing to apply base editors — a version of CRISPR — in children with rare diseases. Now, Science and Retraction Watch have exclusively revealed that Mei died from a severe immune reaction seven days after receiving the treatment, a story that had been kept hidden. The entry on clinicaltrials.gov has not been updated since 2025; and when Qiu and his team published animal studies related to the trial in the journal Nature in early 2026, according to the journalistic investigation, they omitted any reference to Mei and her family.

Early this morning, the Minister of Interior, Fernando Grande-Marlaska, declared a state of emergency of national interest in the Community of Madrid and the province of Ávila due to the forest fires in Villa del Prado, San Martín de Valdeiglesias and Burgohondo. According to Carlos Novillo, the Regional Minister for the Environment, Agriculture and the Interior of the Community of Madrid, the fires were beyond the capacity of the fire services to extinguish and posed a serious threat to the population. The Madrid 112 Security and Emergency Agency has reported that, although the night-time firefighting efforts have been effective, the fires have still not been contained or brought under control. More than 10,000 people remain evacuated.
