Ouest France highlights a study suggesting that while cognitive reasoning peaks between 20 and 30 years, other forms of intelligence, such as moral reasoning and emotional stability, reach their zenith between the ages of 55 and 60. This research underscores the nuanced and evolving nature of intelligence and its implications for leadership and decision-making. On one hand, the findings challenge stereotypes about aging and cognitive decline. On the other hand, they raise questions about how workplaces and societies can better leverage the strengths of older individuals in key roles. Source 1

Contrary to widespread belief, a study covered by Ouest France debunks the myth that there’s an age limit for language acquisition. While children are often considered superior learners, adults retain significant capacity to learn new languages, albeit through different cognitive strategies. This research could influence public education policies and highlight the potential for lifelong learning programs. However, the challenge lies in promoting these opportunities to adults who may feel discouraged by societal misconceptions. Source 2

Science Alert explores how the full moon subtly impacts sleep, with individuals sleeping 15 to 30 minutes less during its brightest phases. While folklore has long associated the moon with erratic behavior and sleep disturbances, the study highlights that artificial light and modern habits, such as screen use, have a far greater impact. The findings suggest a need for better public awareness of light's influence on circadian rhythms, though the persistent myths surrounding lunar effects remain challenging to dispel. Source 15

A study published in the British Medical Journal and reported by Science Alert reveals that ADHD medications, particularly methylphenidate, significantly mitigate risks such as substance misuse, traffic accidents, and suicidal behavior in newly diagnosed patients. These findings highlight the importance of timely diagnosis and treatment. However, the study also raises broader questions about societal stigmas surrounding ADHD and the accessibility of such medications globally. Source 32

Al Jazeera reports that Hurricane Melissa, now a Category 3 storm, is expected to bring catastrophic flooding and landslides to Jamaica, Haiti, and other parts of the Caribbean. Authorities have activated shelters and pre-positioned supplies, but concerns persist about the preparedness of vulnerable communities. The storm underscores the growing frequency of severe weather events attributed to climate change, highlighting the urgent need for global collaboration on mitigation and adaptation strategies.

Research highlighted by Science Alert illustrates how light exposure, whether from the full moon or artificial sources, disrupts sleep patterns and circadian rhythms. The study emphasizes that modern technologies, such as smartphones, play a much larger role than moonlight in contributing to sleep disturbances. This insight could inform public health campaigns on better sleep hygiene, though changing ingrained habits around screen use remains a significant hurdle. Source 15

Ouest France reports that Tropical Storm Melissa has intensified into a hurricane, with sustained winds of 120 km/h, threatening Jamaica and Haiti with severe flooding and landslides. Rapid preparation efforts are underway, though the storm’s potential to isolate communities raises concerns about long-term recovery. The event highlights the importance of disaster readiness in the face of increasingly volatile weather patterns linked to global warming. Source 33

A nuanced study, as featured in Science Alert, dispels myths about the full moon leading to widespread mental health crises. However, it acknowledges that even modest sleep loss during this phase could exacerbate conditions like depression and anxiety for vulnerable individuals. This research suggests that while lunar myths persist culturally, the focus should shift to addressing broader issues of sleep hygiene and mental health support. Source 15

Financial Times and the World Street Journal report on Argentina’s midterm elections, which are critical for determining the future of President Javier Milei’s free-market reforms. The elections come amid a severe currency crisis that has strained the country’s economy. On one hand, Milei’s pro-business policies have attracted international attention. On the other, critics argue that his measures risk deepening inequality. The elections could either bolster his mandate or force a shift toward more interventionist economic policies.

A study covered by Science Alert emphasizes that ADHD medications do more than improve focus; they also reduce risks of substance misuse, accidents, and criminal behavior. In educational contexts, this highlights the need for equitable access to diagnosis and treatment, especially for children who face academic struggles due to untreated ADHD. However, disparities in healthcare access remain a barrier to realizing these benefits for many. Source 32
