TRUMP PICKS ROBERT F KENNEDY JR TO HEAD HHS
President-elect Donald Trump has selected Robert F. Kennedy Jr., known for spreading conspiracy theories, to head the Department of Health and Human Services (HHS). Trump praised Kennedy’s commitment to combating corruption, restoring science-based practices, and tackling the chronic disease epidemic. Kennedy, the son of Robert F. Kennedy, has made controversial claims, including that vaccines cause autism and that Wi-Fi and chemicals in water cause various health issues. His appointment, which needs Senate confirmation, would give him significant influence over public health policies, despite his views often contradicting mainstream science. Kennedy previously ran as an independent presidential candidate before endorsing Trump. The selection has sparked concern among Senate Democrats, who worry about the potential risks to public health. However, Kennedy has received strong support from some Republicans, including Sen. Ron Johnson, who sees him as an opportunity to transform American health policy. (NPR)
YORKTOWN FLUORIDATION DEBATE ESCALATES AMID SAFETY CONCERNS
In Yorktown, New York, a water treatment plant’s fluoride pump malfunctioned in 2012, leading to a decade-long delay in fluoridating the town’s water. By 2024, when fluoridation resumed, public opinion had shifted, with growing concerns about fluoride’s potential effects on brain health. This change was influenced by a federal judge’s ruling, which linked fluoride to reduced IQ levels in children, based on a report from the National Toxicology Program. The debate over water fluoridation, once a public health success, has gained new attention, fueled by erosion of trust in health systems during the pandemic. Critics, including Robert F. Kennedy Jr., have called for fluoride removal, aligning with broader concerns about toxins like microplastics. Despite the historical decline in tooth decay attributed to fluoridation, rising skepticism about its safety, particularly regarding brain development, has led to shifts in policies and a reevaluation of fluoride levels in drinking water.

SCIENTISTS DETECT PARTIAL ARTEMISININ RESISTANCE IN AFRICAN CHILDREN
Scientists have detected partial resistance to artemisinin, a key malaria drug, in children with severe malaria in Africa. This marks the first time such resistance has been observed in this group. Malaria remains a major health crisis in Africa, accounting for 95% of global deaths, with children being the most affected. The study, conducted in Uganda, found that 10% of children showed delayed parasite clearance after treatment with artemisinin, a sign of partial resistance. Mutations in *Plasmodium falciparum*, the malaria parasite, were linked to this resistance. Although all children recovered, some had longer recovery times, raising concerns about the drug’s effectiveness. Researchers also noted potential resistance to lumefantrine, a partner drug in combination treatments, though this requires further study. The emergence of resistance is a significant threat to malaria control, as it could lead to higher mortality rates, though more research is needed to determine its full impact. (Nature)
AZERBAIJAN ACCUSED OF SUPPRESSING ACTIVISTS DURING COP29
Human rights groups are accusing the Azerbaijani government of using COP29 as an opportunity to suppress environmental activists and political opponents. This marks the third consecutive year that a country hosting the climate summit has been accused of restricting protests and curbing civil liberties. Amnesty International reports a significant increase in arrests of activists, journalists, and political opponents since Azerbaijan was chosen to host COP29 in November 2023. Notably, the number of political prisoners has surpassed 300 for the first time in years. Critics, including climate groups, argue that such crackdowns undermine the essential role of civil society in climate change discussions. Azerbaijan’s government, however, denies these claims, asserting that it does not hold political prisoners. Activists have called for a review of the process by which host countries are selected. With tensions rising, the role of civil society in addressing climate change remains at the center of the controversy surrounding COP29. (The Guardian)
NEW AI MODEL EVO PREDICTS GENES AND DESIGNS PROTEINS
A new study published in Science introduces Evo, an advanced AI model trained on billions of lines of genetic sequences, which can predict bacterial and viral genome operations, design proteins, and even generate entire microbial genomes. Evo overcomes previous limitations by expanding the context length, allowing it to identify broader genetic patterns, and improving its resolution to the nucleotide level. Trained on 300 billion nucleotides, Evo demonstrated impressive capabilities, such as predicting mutation effects on proteins and designing new CRISPR genome-editing proteins. Evo outperformed previous models in mutation prediction and created functional versions of Cas9 proteins. The researchers also challenged Evo to generate bacterial genomes, a step toward AI-designed synthetic genomes. While Evo showed some inaccuracies, it performed better than traditional methods, offering a promising tool for research in evolution, disease, and drug development. The project remains open for public use and is not intended for commercialization, emphasizing its research-focused goals. (Science)
US ADULT OBESITY RATES RISE WITH STAGGERING ECONOMIC IMPACT
A new study published in *The Lancet* reveals that nearly three-quarters of U.S. adults are overweight or obese, a significant rise from the 1990s. Obesity rates have doubled among adults and nearly tripled among young women aged 15-24, with one in three children now affected. This trend is linked to numerous health risks, including diabetes, heart disease, and a shortened life expectancy. The economic impact is staggering, with obesity-related medical costs projected to reach $9.1 trillion over the next decade. While the causes are multifactorial, including genetic, environmental, and social factors, experts emphasize the need for systemic change. These factors, such as the widespread availability of processed foods and limited access to fresh produce, contribute to higher obesity rates, particularly in low-income and minority communities. To combat this, experts call for policy reforms, including better access to healthy foods, regulation of unhealthy food marketing, and expanded healthcare coverage for obesity treatments.

FRENCH SEXUAL BEHAVIOR SHIFTED WITH LATER FIRST INTERCOURSE
A recent study by the National Institute of Health and Medical Research reveals a shift in sexual behavior in France, with the median age of first sexual intercourse rising. In 2023, the median age for French women was 18.2, and 17.7 for men, up from 17.3 in 2010. This marks a reversal from previous decades when the age of first sex was decreasing. However, while people are waiting longer to have sex, the number of sexual partners over a lifetime has increased. Women’s average number of partners rose from 3.4 in 1992 to 7.9 in 2023, while men’s rose to 16.4. Despite this, the proportion of people engaging in sexual activity has decreased. The study suggests that fewer people are in stable relationships, and the rise of digital sexuality, especially among younger generations, is transforming how sex is experienced. Additionally, the COVID-19 pandemic may have influenced attitudes toward intimacy. Similar trends have been noted in other countries like Denmark, Sweden, and the US. (The Guardian)
