Science Alert reports that astronomers have identified a new asteroid, 2025 SC79, residing in the Atira asteroid group, whose entire orbit lies within Earth's path. This asteroid is especially notable for its proximity to the Sun and its 128-day orbital period, making it challenging to observe. With an estimated diameter of 700 meters, it poses a significant threat if it were to strike Earth, potentially causing catastrophic damage on a continental scale. The asteroid was detected using advanced technology, such as the Dark Energy Camera, and its composition and origins remain subjects for further study. This discovery underlines the ongoing risks posed by hard-to-detect celestial objects. Source 1

Science Alert reports the unprecedented discovery of mosquitoes in Iceland, previously free of these insects. Entomologist Matthias Alfredsson identified three Culiseta annulata specimens near Reykjavik, with climate change suspected by some as a contributing factor. However, Alfredsson suggests the species' adaptation to colder climates may explain their survival. This development raises concerns about the potential spread of mosquito-borne diseases in areas previously unaffected. Further monitoring is planned to determine the extent of their establishment.

Science Alert highlights a study from the Children's Hospital of Philadelphia showing a significant decline in peanut allergies among children following updated dietary guidelines. These guidelines, introduced in 2015, encouraged early exposure to peanuts, reducing allergy rates from 0.79% to 0.45%. The findings illustrate the effectiveness of public health interventions in addressing rising allergy rates. However, researchers emphasize the need for broader adoption of these practices and further analysis over longer periods to refine prevention strategies. Source 3

A new study covered by Science Alert suggests that prediabetes remission is achievable through dietary and exercise interventions without significant weight loss. Researchers found that improvements in blood sugar levels occurred in participants who maintained or slightly reduced their weight, emphasizing the importance of fat distribution and lifestyle changes over weight metrics. This could shift medical guidelines toward prioritizing blood glucose control over traditional weight-focused approaches to diabetes prevention. Source 4

According to Science Alert, geologists have discovered remnants of proto Earth, dating back 4.5 billion years, in ancient rock samples from Greenland, Canada, and Hawaii. These traces, identified through potassium isotope analysis, have survived despite Earth's dynamic geological processes. Researchers suggest this material predates the collision with Theia, which formed the Moon and altered Earth's composition. This discovery offers invaluable insights into Earth's early formation and the origins of rocky planets. Source 6

A comprehensive study reported by BBC News and the New Scientist has ranked the physical side effects of 30 antidepressants. The research reveals significant variations, such as weight changes, heart rate shifts, and blood pressure impacts, which could influence long-term health. The findings call for more personalized prescribing practices, emphasizing individual health profiles. Experts note that while these drugs are life-saving, their side effects require careful consideration in treatment decisions. Source 32 Source 33

Expanding on antidepressant side effects, New Scientist discusses the development of a digital tool to assist doctors in selecting suitable medications. This tool could revolutionize prescribing practices by accounting for factors like cardiovascular health and metabolic risks. However, some experts caution that the study's eight-week timeframe may not fully capture long-term effects, highlighting the need for further research. Source 33

Al Jazeera reports a study by the European Broadcasting Union and BBC, indicating that 45% of AI-generated responses to news questions contain inaccuracies. Misattributions and lack of appropriate context were common flaws. While AI holds potential for media, researchers urge tech firms to prioritize content accuracy and transparency to maintain public trust. This study underscores the challenges in integrating AI into journalism without compromising factual integrity. Source 7

CNBC reports that India and the United States are nearing a trade agreement, with potential tariff reductions on Indian exports and reduced oil imports from Russia. The deal could lower US tariffs on Indian goods to approximately 15%, down from 50%, while India may increase imports of US agricultural products. This reflects growing economic ties amid geopolitical tensions, though India's energy policy and strategic autonomy remain critical considerations. Source 18

The reduction in peanut allergies among children, as reported by Science Alert, has implications for schools, where severe allergies often lead to restrictions. Early dietary interventions could reduce the burden on educators and healthcare providers while creating safer environments for students. This shift highlights the role of public health policy in shaping educational settings. Source 3
