CAUSE OF SINGAPORE AIRLINES TURBULENCE DROP DETERMINED.
A severe turbulence incident involving a Singapore Airlines flight from London to Singapore last Tuesday caused the aircraft to drop approximately 178 feet in 4.6 seconds. The flight, carrying 211 passengers and 18 crew, encountered the turbulence over Myanmar and was diverted to Bangkok, Thailand. The incident resulted in one fatality—a 73-year-old British passenger who suffered a suspected heart attack—and injuries to dozens more. Many of the injuries were likely due to passengers not wearing seatbelts during the sudden altitude drop, comparable to the height of the Leaning Tower of Pisa. Singapore Airlines is cooperating with the ongoing investigation led by Singapore’s Transport Safety Investigation Bureau and has committed to covering medical and hospital expenses for those affected. The airline emphasized its priority for passenger and crew safety, expressing gratitude for the support from various governmental and medical teams involved. (BBC)
PANDEMIC INCREASES CHILD MYOPIA, EYEBALL ELONGATION RISES
The COVID-19 pandemic significantly altered children’s environments, leading to a surge in screen time and a decrease in outdoor activities. This lifestyle shift caused physical changes in children’s eyes; specifically, their eyeballs elongated to better focus on nearby objects, increasing cases of myopia (short-sightedness). Studies from various regions, including a notable one from Hong Kong, documented a dramatic rise in pathologically elongated eyeballs among children. While elongation enhances near vision, it blurs distant objects, which can be corrected with eyewear but may lead to severe complications like retinal detachment and blindness. Research highlights the preventative benefits of increased outdoor activities, which influence eye development by providing diverse visual experiences and higher light levels that seem to inhibit excessive eyeball elongation. However, implementing increased outdoor time is challenging in urban and academically focused settings, leading researchers to explore indoor interventions like specialized lighting and nature-themed environments to simulate outdoor benefits.

BIRD FLU SPREADS TO DAIRY, MILLIONS OF CHICKENS CULLED.
More than 4 million chickens in Iowa are being culled due to a case of highly pathogenic bird flu detected at an egg farm in Sioux County. This incident is part of an ongoing outbreak that has led to the slaughter of 92.34 million birds across the country since 2022. The outbreak, which has affected poultry for years, is now also impacting dairy cattle. Recently, the virus spread to a Minnesota egg farm, resulting in the death of nearly 1.4 million chickens. Furthermore, bird flu has been confirmed in beef and milk, with cases reported on dairy cattle farms in nine states. Although the risk to the general public is low, workers in close contact with infected animals face higher risks. The USDA ensures that infected animal products do not enter the food supply, maintaining that beef is safe for consumption. Three human cases have been reported, involving agricultural workers.

BIRD FLU CASE IN TEXAS FARM WORKER, CDC CONFIRMS.
In April 2024, a Texas dairy farm worker tested positive for the highly pathogenic avian influenza A(H5N1) after exposure to presumably infected cattle, with the CDC confirming these findings. This case, along with another in Michigan, marks the first known instances of potential cow-to-human transmission of the virus. Since December 2023, A(H5N1) has been detected in U.S. dairy cattle, with current cases found in 52 herds across nine states. The outbreak has also reached other animals, including barn cats and wild birds. High virus levels were found in raw milk from infected cows, emphasizing the risk associated with unpasteurized milk, although pasteurization has been confirmed to deactivate the virus, ensuring the safety of commercial milk. Public health responses have included monitoring exposed individuals, particularly farm workers, and advancing epidemiological investigations to manage and contain the spread. The overall risk to the U.S. public remains low; however, those in direct contact with infected animals or contaminated materials are at increased risk and advised to take preventative measures.

DELHI HITS RECORD 50.5C AMID INTENSE HEATWAVE.
Delhi experienced record-breaking temperatures, reaching 50.5C (122.9F) in the suburb of Mungeshpur, marking the city’s first breach of the 50C threshold. This followed a previous high of 49.9C, surpassing the 2002 record of 49.2C. The India Meteorological Department has warned of severe health impacts, particularly for vulnerable groups, due to the extreme heat. Authorities are also concerned about potential water shortages, prompting measures like reduced water supply to manage the crisis. The ongoing heatwave, attributed to climate change, has intensified daily challenges, affecting everyone from construction workers to market vendors. Measures to mitigate heat stress include altered work hours and hydration strategies. Additionally, Cyclone Remal has brought devastating storms to regions like West Bengal and Mizoram, illustrating the diverse impacts of climate change across the subcontinent. (The Guardian)
AMERICANS LOVE SHRIMP, BUT SUSTAINABILITY CONCERNS LOOM LARGE.
Americans consume less seafood compared to many other nations, but shrimp is a notable exception, with the average American eating nearly six pounds annually. Shrimp is praised for its protein content and low saturated fat, making it heart-healthy, though it lacks other significant nutrients like omega-3 fatty acids. While generally low in environmental toxins like mercury, shrimp farming and harvesting can pose health risks due to preservatives and banned antibiotics found in some imports. Environmentally, shrimp production is highly damaging due to the destruction of crucial habitats like mangrove swamps for farm setups and significant bycatch during wild harvesting, which often involves capturing and killing non-target species. The industry has also faced severe criticisms for labor abuses, including the use of slave and child labor in some countries. Sustainable shrimp purchasing is complex, requiring consumers to be informed about sourcing and production methods, with the most sustainable options often being difficult to find in the U.S. market.

DEADLY DISEASE RAVAGES SEA URCHINS, THREATENS MARINE BALANCE
In early 2023, a deadly sea urchin disease swept through the Gulf of Aqaba, progressing from northern Aqaba, Jordan, to the Sinai Peninsula in Egypt, leaving vast numbers of sea urchins dead. Initially detected in the Caribbean Sea in early 2022, this plague was caused by a scuticociliate pathogen, a type of single-celled organism not previously known to affect sea urchins. The disease rapidly spread, causing massive urchin die-offs along the Mediterranean coast and moving swiftly to the Red Sea and western Indian Ocean. This pathogen, which also affects other marine species, poses a severe threat to marine ecosystems, as sea urchins play a crucial role in controlling algae growth on reefs. The overgrowth of algae, resulting from the decline in urchin populations, can smother corals and disrupt the ecological balance, potentially leading to broader environmental impacts. The spread of this pathogen may be facilitated by global shipping, and experts suggest testing ballast water as a containment strategy. To safeguard the future of sea urchins, measures like maintaining quarantined populations in captivity are being considered. (Science)
SMITHSONIAN ZOO TO WELCOME PANDAS IN RENEWED DIPLOMACY EFFORT
The Smithsonian’s National Zoo in Washington, D.C., is set to welcome back giant pandas after a year-long absence. The China Wildlife Conservation Association (CWCA) will loan two young pandas, Bao Li and Qing Bao, to the zoo for a decade in exchange for an annual fee of $1 million, aimed at funding conservation efforts in China. These pandas, descendants of previous residents, are expected to arrive later this year following a period of quarantine. Their arrival is part of a broader initiative to continue the 52-year tradition of panda diplomacy, which began with a casual comment from Pat Nixon during a 1972 visit to China. The zoo is currently renovating the giant panda habitat, seeking $25 million in donations to support this and other related costs. This re-introduction of pandas to the zoo aims to renew public engagement and support for conservation efforts, continuing a legacy that includes a history of both joyous arrivals and natural challenges in breeding.
