PANDEMIC AFTEREFFECTS RESHAPE AMERICANS' LIVES AND PRIORITIES.

Four years after the Trump administration declared a national emergency due to COVID-19, its impact still lingers for many Americans. Jessie Thompson, a Chicago mother, cherishes the flexible work schedule that allows her more family time, seeing it as a positive change from the pandemic. Despite the World Health Organization ending its global health emergency declaration in May 2023, the effects of the pandemic, including long COVID, continue to affect millions. Individuals like Melody Condon have lost trust in others due to perceived carelessness about health safety measures. Meanwhile, Paris Dolfman's life has been drastically altered by long COVID, forcing her to find joy in small things from her bedridden state. Clint Newman, after a year of isolation, experienced a deep psychological impact but found love and decided against loneliness. Cindy Esch's adventure-filled life was curtailed by long COVID, leading to significant lifestyle changes to protect her health. These stories highlight the enduring changes and adaptations in American life, signaling a lasting shift in societal norms and personal priorities post-pandemic. (New York Times)

HUBBLE TENSION UNRAVELS COSMIC EXPANSION MYSTERY PUZZLE.

The "Hubble Tension," a major cosmological puzzle, revolves around discrepancies in the measured rate of the universe's expansion, which is faster than expected from early universe observations and theoretical predictions. This inconsistency raises questions about potential errors in measurement techniques or the necessity for new physics. The Hubble Space Telescope and the James Webb Space Telescope have collaborated, providing definitive measurements to challenge the idea that measurement errors could explain the discrepancy. Adam Riess, a Nobel Prize-winning physicist, emphasizes that this collaboration negates measurement errors, suggesting a fundamental misunderstanding of the universe's evolution. Observations, including those of Cepheid variable stars, have confirmed Hubble's accuracy, ruling out measurement error as the cause of the Hubble Tension with high confidence. This sets the stage for future observatories, like NASA's Nancy Grace Roman Space Telescope and ESA's Euclid observatory, to explore the expansion of the universe further and the role of dark energy. The findings, published in The Astrophysical Journal Letters in February 2024, underscore the critical role of international cooperation and advanced space telescopes in expanding our cosmic knowledge.

OPENAI'S SORA IGNITES DEBATE OVER AI VIDEO POTENTIAL.

The release of OpenAI's Sora, a text-to-video AI tool, has sparked both excitement and concern among researchers due to its potential for misuse, particularly in creating photorealistic videos from text prompts. Tracy Harwood, a digital-culture specialist, expressed surprise at the rapid development of text-to-video AI, highlighting fears that it could significantly impact global politics and misinformation, especially with important upcoming elections. OpenAI aims to mitigate potential harms by making Sora available for "red teaming" to identify risks. While Sora showcases advanced capabilities, other text-to-video technologies like Gen-2 and Lumiere have been described as underwhelming by Harwood, requiring specific prompts to produce compelling content. Misinformation remains a critical challenge, with potential solutions like watermarking being considered, though they may not be entirely effective. Despite these concerns, there are optimistic views on text-to-video AI's benefits in fields such as education, healthcare, and data management. However, it also raises issues in creative industries and necessitates a societal shift in evaluating and consuming media content. (Nature)

UK'S LACK OF HOME INSULATION LINKED TO WINTER DEATHS.

A Greenpeace report highlights that the UK's failure to insulate homes adequately has resulted in an average of 58 deaths daily during winter since 2013, following government cuts to insulation support. Greenpeace UK's fuel poverty campaigner, Paul Morozzo, criticized successive governments for exacerbating the public health crisis by reducing insulation funding. Addressing this issue could save lives, lower bills, alleviate fuel poverty, and cut carbon emissions. Despite experts, including Greenpeace, recommending an annual £6bn investment in housing insulation, the Labour party recently reduced its insulation spending plans by over 70%. Greenpeace activists demonstrated the issue by creating a mock cemetery near the Houses of Parliament, emphasizing the UK's inefficient housing and the associated high levels of fuel poverty and health costs. Housing accounts for 14% of the UK's greenhouse gas emissions, underscoring the need for high-quality, safe insulation to prevent deaths, create jobs, and reduce energy waste. (The Guardian)

JAPANESE STARTUP'S ROCKET EXPLODES IN SATELLITE LAUNCH ATTEMPT.

A Japanese startup, Space One, faced a setback when its Kairos rocket exploded shortly after launch from Wakayama prefecture, aiming to be the first Japanese private firm to place a satellite into orbit. The 18m solid-fuel rocket, carrying a government test satellite, failed around five seconds post-launch, causing no injuries but disappointment among spectators and officials. Space One, established in 2018 by a consortium including Canon Electronics and IHI, cited an autonomous flight-termination system activation due to an unspecified problem. This incident adds to Japan's recent challenges in space endeavors, including previous failures of other rockets. However, it follows Japan's successful launch of its new H3 flagship rocket and a moon probe landing, highlighting the country's continued ambition in space exploration and satellite-launch market entry. The failure impacts Space One's supporters and Japanese space industry stocks, yet the commitment to overcoming setbacks remains strong. (Channel News Asia)

LADYBIRD LARVAE TURN INVASIVE PREY'S TOXIN AGAINST PREDATORS.

In Valencia, Spain, the mealybug ladybird larvae have developed a defense against predatory ants by expelling hemolymph containing carminic acid, a substance acquired from their diet of the invasive prickly pear cochineal bugs. This finding challenges the assumption that such toxin sequestration requires a long coevolutionary history between species. Entomologist Ángel Plata and his team discovered that despite being native to different continents, the mealybug ladybird can utilize the carminic acid from cochineal bugs for protection. This adaptation demonstrates rapid evolutionary responses to new environmental challenges and has implications for biological pest control, particularly in agricultural settings where the mealybug ladybird is beneficial. However, the study also highlights the unpredictable consequences of species invasions on native ecosystems, emphasizing the need for further research as global trade and climate change accelerate the spread of invasive species.

PREHISTORIC BIRD NAMED FOR ATTENBOROUGH SHEDS LIGHT ON EVOLUTION.

The discovery of Imparavis attenboroughi, a prehistoric bird species from 120 million years ago, is offering new insights into the evolution of modern birds from dinosaurs. Named to honor David Attenborough, this bird is notable for its lack of teeth—a rare trait among its contemporaries, as most prehistoric birds had teeth. This species, belonging to the extinct enantiornithines or "opposite birds" group, is the earliest known bird of this kind without teeth, indicating that toothlessness occurred nearly 48 million years earlier than previously thought. Found in northeastern China, Imparavis displayed unique anatomical features, such as independently moving "fingers" and unusual forelimbs that could suggest powerful wing beats. However, the absence of a gizzard and its toothless beak leave its diet and method of digestion a mystery. The discovery raises questions about the diverse enantiornithines' extinction alongside dinosaurs, contrasting with the survival of modern birds' ancestors. Attenborough expressed honor over the naming, which reflects his significant influence on natural science and conservation awareness. (Smithsonian)
