Microplastics Found in Human Brains: Study Reveals Disturbing Accumulation

ESSpain|

A recent study published in the journal Nature has detected alarming levels of microplastics in human brain samples, revealing concentrations seven to 30 times higher than in the liver or kidneys. Researchers analyzed brain samples from cadavers dating from 2016 to 2024 and observed a significant rise in microplastic content, attributed to increased plastic exposure in recent years. According to Matthew J. Campbell, lead author and biologist at the New Mexico Center for Metals, while the findings are concerning, the absence of higher concentrations of nanoplastics in older adults suggests potential elimination over time.

Microplastics, tiny particles resulting from larger plastic waste degradation, are increasingly prevalent due to rising global plastic production, which doubled to 460 million tons between 2000 and 2019. The environmental impact is profound, with over 22% of produced plastic accumulating improperly and entering the food chain. Eva Jiménez-Guri from the University of Exeter emphasizes the importance of understanding both the concentrations and locations of plastic in the body. However, some experts, including Roberto Rosal from the University of Alcalá, express skepticism about the study’s findings, citing potential contamination issues.

Major Breakthrough in Evolutionary Biology Reveals Path from Simple to Complex Cells

A new study has unveiled insights into how simple cells evolved into complex life forms over two billion years ago. Conducted by researchers from Spain and published in the journal PNAS, the research attributes this evolutionary leap to the limitations in protein size, which forced an essential shift in genetic regulation, as explained by co-author Jordi Bascompte of the University of Zurich. Historically, the transition from prokaryotic cells (simple bacteria) to eukaryotic cells (more complex organisms) has puzzled scientists. Bascompte cites British biochemist Nick Lane's assertion regarding the lack of known intermediaries between these cellular forms. The research posits that as proteins could no longer elongate effectively, cells began utilizing non-coding parts of DNA, such as introns, leading to new genetic regulatory strategies. Biotechnologist César de la Fuente from the University of Pennsylvania praised the study's interdisciplinary approach, noting its potential to explain the complexity of multicellular organisms. The collaborative effort from various scientific disciplines reflects a quest for answers that has spanned three decades, illustrating the intricate relationship between biology and computational algorithms.

Glaciers Losing Ice at Alarming Rate, Warns World Meteorological Organization

The World Meteorological Organization (WMO) has issued a stark warning that the world's glaciers are losing ice at an unprecedented rate, equating to three Olympic-sized swimming pools every second. This announcement coincides with the first World Glacier Day on March 21, amidst the International Year of Glaciers’ Conservation. According to the WMO Secretary-General Celeste Saulo, the rapid retreat of glaciers presents a serious threat to global economies and ecosystems, with implications reaching far beyond mountain regions. Recent research published in *Nature*, led by the World Glacier Monitoring Service, reveals that glaciers have lost an average of 273 billion tons of ice annually since 2000, with a 36% increase in ice loss in the last decade. This study indicates that glaciers in regions like the Alps and Pyrenees have suffered the most, with potential long-term impacts on freshwater supplies, particularly in Asia. The report emphasizes the urgent need for climate action, as failing to mitigate further warming could result in the loss of many glaciers globally by the end of the century, potentially raising sea levels by 30–35 centimeters.

Luis Rubiales Found Guilty of Sexual Assault in Hermoso Case

Former Spanish football chief Luis Rubiales has been found guilty of sexually assaulting player Jenni Hermoso by kissing her without consent after the Women's World Cup final in August 2023. Spain's High Court has ordered Rubiales to pay a fine exceeding €10,000 (approximately $11,000) but acquitted him of coercion, according to court documents. During the trial, Hermoso testified that she "never" consented to the kiss, calling the incident a "taint" on what was otherwise "one of the happiest days" of her life. Rubiales, 47, claimed the kiss was consensual and occurred in a "moment of jubilation." However, the controversy overshadowed Spain's historic victory, prompting widespread discussions around sexism in sports and the push for equal treatment of female athletes. The case and its ramifications have sparked significant public debate and advocacy for greater accountability and respect for women in sports. The ruling marks a pivotal moment in the evolving conversation about consent and harassment in the sporting world.
