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.

Air conditioning in buildings is necessary to combat the high temperatures of summers, which are becoming increasingly long and hot; however, it is not without controversy due to its energy consumption and environmental impact. Today, the WHO is presenting its new guidance on health and heat action plans, in which it acknowledges that air conditioning is problematic, while also emphasizing the need for vulnerable populations to have access to these systems. In a recent briefing organized by SMC Spain, we analyzed its role in the fight against global warming.

Craig Venter, the American biologist and entrepreneur who founded Celera Genomics to launch his own Human Genome Project in 1999 outside the public consortium, died Wednesday in San Diego at the age of 79, according to a statement from the J. Craig Venter Institute, which he led. Among other achievements, Venter completed the first full sequencing of a living organism’s genetic material and announced that he had succeeded in creating synthetic life.

In February 2025, lithium concentrations suddenly increased around 96 km above sea level some 20 hours after a SpaceX Falcon 9 launch vehicle re-entered the atmosphere. This is the first direct detection of pollution in the upper atmosphere due to the re-entry of a spacecraft, according to a study published in Communications Earth & Environment. Lithium is used in spacecraft components, but it is only found naturally at these altitudes in trace amounts, and its accumulation could have consequences on the climate.

In a press release, the European Southern Observatory (ESO) warns that a huge industrial complex threatens the skies above the Paranal Observatory in Chile's Atacama Desert. According to ESO, on 24 December, AES Andes, a subsidiary of the US electricity company AES Corporation, submitted for environmental impact assessment a project for a huge industrial complex that would be located between 5 and 11 kilometres from the Paranal telescopes. This astronomical observatory, the darkest in the world, has led to important breakthroughs, such as the first image of an exoplanet or the confirmation of the accelerated expansion of the universe.

Men often struggle with the transition to fatherhood due to a lack of information and emotional support targeted to their needs, suggests a review of the available qualitative evidence, published in the open access journal BMJ Open. The researchers say there needs to be a greater focus on clinical practice, antenatal services and research into men's unique experiences during the perinatal period, which encompasses pregnancy and the first 12 months after birth.

A team of researchers led by the Center for Genomic Regulation in Barcelona has mapped the human spliceosome for the first time. This complex and partially unknown cellular machinery is responsible for cutting and splicing the RNA fragments encoded by genes in different ways, making it possible to obtain a wide variety of proteins from the same sequence. Its alteration is related to processes such as cancer, neurodegenerative processes or various rare diseases. According to the researchers, who publish the results in the journal Science, “by knowing exactly what each part does, we can find completely new angles to address a broad spectrum of diseases”.

A new study presented at the annual meeting of the European Association for the Study of Diabetes (EASD), being held in Madrid from September 9-13, and published simultaneously in the New England Journal of Medicine (NEJM), has revealed that liraglutide, an anti-obesity drug, is safe and effective in children aged 6-12 years.

Some 90 % of coastal and lowland wine-growing regions in Spain, Italy, Greece and southern California are at risk from extreme events, such as excessive droughts and heat waves, according to a review published in Nature Reviews Earth & Environment. The article summarises the expected changes and the adaptations that wine producers will need to make.
