Seawater temperatures at the tip of Florida reached unprecedented highs, exceeding 100 degrees Fahrenheit (37.8 Celsius) for two consecutive days. This could potentially mark the hottest seawater ever recorded, pending further analysis due to specific conditions that could impact the reading. The extreme temperatures, potentially influenced by nearby warm land in the Everglades National Park, have had destructive effects on local marine life, particularly coral reefs. Coral bleaching and death, once rare phenomena, have become increasingly common as temperatures rise due to climate change. Ian Enochs, head of the coral program at the National Oceanic and Atmospheric Administration (NOAA), expressed concern over the early onset of these conditions. These events coincide with record-breaking sea surface temperatures worldwide, including an increase of 9-11 degrees Fahrenheit (5-6 Celsius) in areas near Newfoundland. While the Florida measurement may not qualify for an official record due to the area’s shallow nature and presence of sea grasses, it nonetheless signals a worrying trend in the face of global climate change.

Japan’s population is experiencing significant changes, with the number of Japanese people decreasing at a record pace while foreign residents rise to nearly 3 million, according to government data. In 2023, the Japanese population fell by about 800,000 to 122.42 million, marking a 14-year decline. This trend was observed across all 47 prefectures. However, foreign residents increased by 10.7% from the previous year to a record 2.99 million. Japan’s total population decreased to 125.42 million, a fall attributed to a low birth rate since its peak in 2008. The government intends to address the situation by promoting labor market reforms, encouraging the employment of women and the elderly, and allocating 3.5 trillion yen ($25 billion) annually for child care and parental support. To achieve projected economic growth, Japan needs approximately four times its current foreign workforce by 2040, according to Tokyo-based think tanks. (Reuters)
Scientists have discovered a plethora of novel giant viruses in the soil of Harvard Forest, Massachusetts. These unusually large viruses can reach sizes similar to bacteria and carry immense genomes, bigger than those of much more complex organisms. Until now, research has primarily focused on those found in freshwater environments. However, genomic sequencing from the forest soil unveiled a new abundance of giant viruses, leading to a greater understanding of their ecological diversity and evolutionary significance. Using electron microscopy, researchers identified a remarkable variety of shapes and structures in these viruses, far beyond the expected 20-sided icosahedral shapes. This includes tails, altered points, multilayered structures, and even tubular appendages, prompting the team to label them as “Gorgon” morphology. Many of these potential viral particles were coated with hairlike projections of varying lengths, thickness, density, and shapes. (Science)
Ranga Dias, a physicist at the University of Rochester known for his controversial claims about room-temperature superconductors, is facing a second retraction due to alleged data fabrication. Physical Review Letters (PRL) is retracting a paper Dias published in 2021, following allegations of substantial plagiarism in his PhD thesis and an earlier retraction by Nature. An investigation into a study Dias conducted on the electrical properties of manganese disulfide found compelling evidence of data fabrication, leading to the paper’s retraction. As part of the investigation, co-author Ashkan Salamat provided alleged raw data that didn’t match the figures in the paper, further solidifying the case against Dias. Despite these allegations, Dias continues to deny any misconduct, stating his commitment to room-temperature superconductivity research. However, the mounting evidence against Dias’s integrity has led many in the scientific community to scrutinize his recent work with suspicion. (Nature)
A Netflix documentary showcased a cave in South Africa filled with bone fossils that scientists argue are the earliest-known human burials. However, the evidence presented was criticized as “inadequate” by four peer-reviewing scientists. The controversy is part of a high-profile examination of eLife’s new publishing model, which publishes papers with peer reviews but neither accepts nor rejects them. The research on Homo naledi, a quarter-of-a-million-year-old human relative, thus exists in a contested zone between publicity and shifting peer review practices. Despite criticism, the research team led by palaeoanthropologist Lee Berger remains confident in their findings, claiming the burials and possible symbolic behavior suggest a reevaluation of the cognitive abilities of early hominins. Critics argue the evidence, including bone arrangement and wall scratchings, doesn’t definitively prove intentional burial or engraving by Homo naledi. This situation underscores ongoing debates around peer review and the communication of scientific findings. (Nature)
Volunteers are striving to save dozens of stranded long-finned pilot whales in Western Australia, with more than 50 already dead. Nearly 100 whales stranded themselves on the beach near the city of Albany. Throughout Tuesday, the pod moved closer to shore, eventually covering a large stretch of the beach. While it remains unclear why this stranding phenomenon occurs, it’s heartbreakingly common; similar incidents occurred in Tasmania and New Zealand last year, killing hundreds of whales. Peter Hartley, from the Department of Biodiversity, Conservation and Attractions, said the team, including Perth Zoo veterinarians and marine fauna experts, is working to save as many whales as possible. Wildlife scientist Vanessa Pirotta suggested the whales could be disoriented, though the exact reasons for mass strandings remain elusive. Hundreds of volunteers have offered assistance, resulting in authorities urging the public to avoid the beach. (The Associated Press)
Porsche has announced plans to gradually transition to electric vehicles, aiming for 80% of its sales to be electric by 2030. The iconic 911 model is expected to be the only internal-combustion vehicle in the lineup. The company, known for investing in e-fuels, will begin by electrifying the compact SUV Macan, followed by the 718 sports car and the best-selling Cayenne. E-fuels, made from carbon dioxide and renewable hydrogen, are seen as carbon-neutral, but are currently targeted at the aviation industry and heavy vehicles. Despite major automakers committing over $1.2 trillion to electrification, e-fuel startups have attracted less than $1 billion in investment. Luxury car manufacturers, including Ferrari and Morgan Motor Co, are also considering e-fuels, despite the high costs. Meanwhile, smaller automakers are targeting wealthy customers with high-performance e-fuel models. (Reuters)
