TWO ASTEROIDS TO PASS EARTH SAFELY THIS WEEK
This week, two significant asteroids are set to pass near Earth, but they pose no risk of impact. The larger asteroid, (415029) 2011 UL21, approximately 7,600 feet long, will be visible on Thursday, flying over 17 times the distance to the moon. It requires a strong telescope to view. The smaller asteroid, 2024 MK, measuring between 400 and 850 feet, will be closer, passing at 75% of the lunar distance on Saturday. This asteroid may be visible with good binoculars or a backyard telescope, especially in clear skies. Juan Luis Cano from the Planetary Defense Office notes that spotting 2024 MK requires skill due to its speed. Best views might be in the U.S. Southwest or from Hawaii’s Mauna Kea. This close approach is rare, happening about every decade. The event coincides with preparations for Asteroid Day on June 30, aimed at raising awareness about potential asteroid impacts. New technologies and telescopes, like the Vera C. Rubin Observatory and NASA’s Near-Earth Object Surveyor, are enhancing our ability to detect such threats. (New York Times)
ULTRASOUND STICKERS OFFER DEEPER INSIGHT INTO HEALTH
In Cambridge, Massachusetts, a runner experimented with ultrasound stickers, offering a real-time view of internal physiological processes via a smartphone. These wearable ultrasound devices are a step towards advanced health monitoring, displaying live images of organs and blood flow. While current wearables like Fitbits track basic health metrics, ultrasound stickers delve deeper, imaging organs which other non-invasive methods cannot. However, integrating ultrasound into wearable technology faces challenges, including device miniaturization and continuous data transmission. The article discusses the development of small, skin-adhering ultrasound devices that provide continuous, deep tissue imaging and are connected wirelessly to smartphones for data analysis. Key advancements are needed in device flexibility, battery life, and data privacy to ensure effectiveness and security. This technology could revolutionize healthcare by enabling continuous monitoring and early disease detection, making medical imaging more accessible, especially in remote areas. As the technology advances, collaborations among scientists, engineers, and regulatory bodies will be crucial to address these challenges and fully integrate wearable ultrasound into clinical practice.

PROFESSOR ADVOCATES TOBACCO-STYLE WARNINGS FOR PROCESSED FOODS
Professor Carlos Monteiro, from the University of São Paulo, warns of the health risks posed by ultra-processed foods (UPFs), advocating for tobacco-style warnings and stricter regulations. Speaking at the International Congress on Obesity, he notes that UPFs are increasingly replacing healthier, less processed options worldwide, contributing to diet-related chronic diseases such as obesity, diabetes, and heart disease. Monteiro, who helped develop the food classification system “Nova” fifteen years ago, categorizes food into four groups based on the level of processing. He argues that public health campaigns similar to those against tobacco are necessary to combat UPFs, suggesting measures like advertising bans, front-of-pack warnings, heavy taxation, and banning sales in schools and health facilities. However, Dr. Hilda Mulrooney from London Metropolitan University critiques the comparison between UPFs and tobacco, pointing out that while tobacco is universally harmful, people require nutrients found in some UPFs, albeit in much smaller quantities than currently consumed.

MICROBIAL CANCER LINK STUDY RETRACTED AMID METHODOLOGICAL ERRORS
A significant paper that linked specific microbial signatures to various human cancers was retracted after the findings were deemed unsupported. Published in “Nature” in 2020, the study utilized machine learning to correlate certain microbes with cancer types, but faced criticism for methodological errors. This led to an initial editorial note and eventually a retraction. All authors consented to the withdrawal, recognizing issues with the data and conclusions. The paper’s lead, Rob Knight, maintains belief in the core findings and plans to validate them with enhanced methods in future research. The retraction has prompted a reassessment of related studies, including works that relied on the data from the 2020 paper. Knight’s team’s initial research supported the founding of Micronoma, a company developing a cancer diagnosis tool, which has since faced operational challenges. Critics and other researchers see the retraction as a reminder of the need for rigor in scientific research, especially when employing complex data analyses like those used in studying the microbiome.

ESTONIANS FLOCK TO GENOME PROJECT AS EUROPEAN FOOTBALL CONTINUES
While much of Europe focuses on the European Football Championships, many Estonians, whose team did not qualify, are engrossed in exploring their own genomes. Approximately 210,000 Estonians, or 20% of the adult population, have contributed to the national biobank and now have the opportunity to learn about their genetic traits, disease risks, ancestry, and how they metabolize substances like caffeine. The overwhelming interest crashed parts of the online portal shortly after its launch, highlighting the high genetic literacy in Estonia. The Estonian Biobank, established by a 2000 law, is one of the largest efforts to return genetic results to participants, a practice not common in most biobanks. The project not only offers insights into health-related genetic traits but also provides personalized advice on lifestyle changes to mitigate disease risks. This initiative is part of a broader trend of sharing genetic information with biobank participants, seen in other studies like the US-government-funded All of Us research. (Nature)
ANCIENT SKULL HINTS AT DOWN SYNDROME IN NEANDERTHALS
Anthropologists studying bones at Cova Negra, a Spanish cave, discovered a child’s skull bone from over 146,000 years ago, showing anomalies indicative of Down syndrome, potentially the oldest known case. This finding suggests that Neanderthals cared for vulnerable community members, as the child lived to about age 6 despite likely challenges such as hearing loss and balance issues. The study, published in Science Advances, highlights the Neanderthals’ compassionate social structure. High-resolution scans of the inner ear bone showed significant differences compared to typical Neanderthal structures, supporting the diagnosis. Researchers plan to confirm the condition through DNA analysis. This case, along with previous findings like the cared-for Neanderthal man at Shanidar Cave, reinforces the idea that Neanderthals provided care not for reciprocation but out of genuine concern, demonstrating their capacity for complex planning and empathetic behavior. This caring behavior is seen as both a survival strategy and a form of altruism. (Science)
REWILDING SUCCESS ON SUSSEX COAST AS MARINE LIFE REBOUNDS
On Shoreham-by-Sea’s west beach, Eric Smith and George Short, part of the Sussex Bay conservation group, are witnessing marine habitat recovery, evidenced by the debris like cuttlefish bones and whelk eggs left by the tides. Smith recalls the rich kelp forests of his youth, which were destroyed by intensive trawling but are now showing signs of recovery due to conservation efforts. This rejuvenation is part of a larger, pioneering project aimed at rewilding a 100-mile stretch of the Sussex coastline, encompassing river, land, and seascape restoration, supported by local councils and a Rewilding Britain grant. The project has successfully reintroduced species like oysters and is working on expanding kelp forests, which are crucial for marine biodiversity. Smith, despite his physical limitations, continues to dive and document the regenerating underwater life. The project not only supports marine life but also boosts local tourism by increasing awareness of the region’s natural wealth. It’s a testament to community and ecological resilience, showing that nature can recover if given space and protection. (The Guardian)
