A humpback whale, approximately 10 metres long, has become stranded for the third time on Germany's Baltic coast. The mammal, believed to be male, appeared weakened and sick on Sunday, struggling to find a route back to the Atlantic.**The prognosis for the whale's survival is grim**, according to Burkard Baschek, a marine scientist. The whale's breathing frequency has reduced, and it no longer exhibits reactions to nearby vessels.Till Backhaus, the environment minister of Mecklenburg-Western Pomerania, established a 500-metre restricted area around the animal to give it a chance to rest and hopefully free itself. However, **the chances of success are relatively slim**, according to Baschek.The whale was first spotted in the Baltic on 3 March and reported stranded on a sandbank last week. Authorities used an excavator to deepen a channel and boats to create waves to help free the mammal, which was nicknamed Timmy. Despite being freed once, it became trapped again on Sunday.**The whale's respiratory rate has dropped considerably**, and it is not moving, according to Stephanie Gross of the Institute for Terrestrial and Aquatic Wildlife Research. Even if the whale frees itself again, it would need to navigate narrow straits and approximately 310 miles to reach relative safety.Humpback whales are not native to the Baltic, and experts suspect that the young whale followed a shoal of fish or became disoriented by the noise of a submarine. **The lack of salt concentration and nutrition in Baltic waters makes it difficult for humpbacks to survive in the long term**.

Robert F Kennedy Jr, the US health secretary, has unveiled a chaotic and unpredictable agenda for public health policy under his 'Make America Healthy Again' (Maha) initiative. His approach tends to favor personal choice and autonomy over large-scale, mandatory public health interventions, such as childhood vaccine requirements.The Maha agenda has raised concerns over the potential risks associated with injectable peptide drugs. Mr. Kennedy plans to open up the sale of 'about 14' of these drugs to the public, despite the US Food and Drug Administration (FDA) restricting 17 peptides in 2023 due to 'potential significant safety risks'. None of these peptides have been proven to be safe or effective for human use.The peptides in question are often promoted for biological enhancement, such as increasing muscle mass or cognitive benefits, but the evidence for these effects in humans is thin. Reports of people self-administering peptide therapies, usually bought from China 'for research use only', are widespread, particularly in Silicon Valley.The Maha project wants to make the grey market the only market, effectively sanctioning mass public use of unproven treatments. Peptides are clearly drugs and shouldn’t be allowed for widespread use without rigorous clinical trials. Opening loopholes for sale would undermine the precautionary principle that has successfully led public health policy for generations.It is also worth noting that other governments are unlikely to be as cavalier as Mr. Kennedy about peptides. However, people everywhere will continue to call for more personal choice and more bodily autonomy, and those conversations are important. The case for safety, proof, and regulation must be made to ensure that public health policy prioritizes the well-being of individuals.

The concept of luck has long been shrouded in mystery, often attributed to chance or fate. However, behavioural neuroscience has made significant strides in uncovering the underlying mechanisms that govern luck. According to research, luck is not just a roll of the dice, but rather a complex interplay of brain chemistry and behaviour that can be influenced and cultivated.The neuroscience behind luck reveals that it operates through identifiable patterns of brain chemistry and behaviour. Studies have shown that the consistently lucky are not blessed by fate, but rather, they possess a unique set of habits and characteristics that enable them to capitalize on opportunities and navigate challenges more effectively. Brain imaging techniques have even identified specific regions of the brain that are activated when individuals perceive themselves as lucky, shifting their perception from threat-detection mode to opportunity-recognition mode.Serotonin production, regulated by morning sunlight, tryptophan-rich foods, and a regular sleep-wake cycle, plays a critical role in determining one's luck. Individuals who prioritize these factors are more likely to experience a boost in serotonin levels, which in turn, enhances their mood, social confidence, and resilience. Conversely, those who lead erratic lifestyles and neglect these factors may find themselves chronically sleep-deprived and less likely to encounter fortunate events.Lucky individuals also tend to possess a clear awareness of their interests and passions, which guides their decision-making and behaviour. By following their 'fascination compass', they are more likely to stumble upon opportunities and experiences that align with their values and goals. Novelty-seeking and a willingness to take calculated risks also characterize lucky individuals, as they understand that each small departure from routine can be a ticket to new experiences and encounters.Generosity and a willingness to help others without expectation of return are also key characteristics of lucky individuals. Brain imaging studies have shown that acts of genuine generosity activate the brain's deepest reward centre, releasing feel-good chemicals that reinforce positive behaviours and build social capital. By investing in others and cultivating meaningful relationships, lucky individuals create a network of opportunities and support that can help them navigate life's challenges.In conclusion, luck is not just a matter of chance, but rather a complex interplay of brain chemistry, behaviour, and habit. By understanding the underlying mechanisms that govern luck and incorporating these insights into daily life, individuals can increase their chances of experiencing fortunate events and leading a more fulfilling life.

For the first time, a team of researchers has successfully mapped out the intricate network of nerves within the clitoris, a crucial organ responsible for female sexual pleasure. This achievement comes almost 30 years after a similar mapping was completed for the penis. The 3D scans of two female pelvises, donated through a body donor program, have provided unprecedented detail on the five complex tree-like branching nerves running through the clitoris. The widest of these nerves measures 0.7mm across. Led by Ju Young Lee, a research associate at Amsterdam University Medical Center, the study challenges existing knowledge about the anatomy of the clitoris. For instance, previous research suggested that the dorsal nerve of the clitoris diminished as it approached the glans, but the new scans show that it continues strongly to the end. The clitoris, one of the least-studied organs in the human body, has been neglected by researchers for far too long, according to Melbourne urologist Helen O'Connell. She notes that cultural taboos around female sexuality have hindered scientific investigations, and it wasn't until 1995 that the clitoris was included in standard anatomy textbooks. The mapping of clitoral nerves is expected to inform reconstructive surgery after female genital mutilation, which affects over 230 million girls and women worldwide. A better understanding of the nerve pathways could reduce the number of women who experience a decline in orgasmic experience after surgery. This breakthrough also has implications for vulvar cancer treatment, gender reassignment surgery, and genital cosmetic surgeries. As Lee hopes to open a clitoris exhibition to expand knowledge about the organ, inspired by the Vagina Museum in London, the study marks a significant step forward in understanding female sexual function and anatomy.

The UK television landscape has undergone a significant change this Easter, as new regulations banning junk food advertising before 9pm have taken effect. For the first time, viewers will not be subjected to a barrage of advertisements for chocolate eggs and hot cross buns during their Easter celebrations.The regulations, which came into force at the beginning of the year, aim to tackle rising childhood obesity by prohibiting products high in fat, sugar, and salt from appearing in TV ads before 9pm. This move has resulted in a sugar-free viewing experience for UK audiences during Easter.The impact on the advertising industry has been notable, with TV advertising spending by confectionery and snacks brands almost halving year-on-year between October and February. Overall TV ad spend is down at least 15% year-on-year.Industry bodies and broadcasters have argued that the ban is more political PR than an effective policy, with the chief executive of ITV, Carolyn McCall, and former Channel 4 boss, Alex Mahon, pointing out that the government’s own research showed that the number of calories saved would be 1.7 a day, about a third of a Smartie.Campaigners argue that big food companies are compensating for the ban by upping marketing budgets on other media, such as outdoor media and radio. A battle is already brewing over the likely introduction of further restrictions, with the government launching a consultation on adopting a newer nutrient profiling model that would deem a far wider range of products too high in fat, salt, and sugar.

Yemen's Houthi rebels have launched a barrage of ballistic missiles at Israel, marking their first such attack since the US-Israel war on Iran began. The assault was announced by Brigadier-General Yahya Saree, a military spokesman for the Houthis, on their Al-Masirah satellite television. The attack targeted what Saree described as 'sensitive Israeli military sites' in southern Israel. The Israeli military reported intercepting one of the missiles. This development comes as Iran and Hezbollah continue to fire on Israel, with sirens sounding around Beer Sheba and near Israel's main nuclear research centre. Saree stated that the strikes 'will continue until the declared objectives are achieved, as stated in the previous statement by the armed forces, and until the aggression against all fronts of the resistance ceases'. This escalation follows a vague statement by Saree on Friday signaling the rebels' intention to join the conflict. The Houthis, who have controlled Yemen's capital, Sanaa, since 2014, had previously stayed out of the US-Israel war. However, they have been involved in attacks on shipping vessels during the Israel-Hamas war, disrupting commercial transit in the Red Sea. Over 100 merchant vessels were attacked with missiles and drones, resulting in two ships sinking and four sailors killed between November 2023 and January 2025. Experts consider the Houthis' entry into the US-Israeli war on Iran as 'very significant'. Mohamad Elmasry, a professor of Media Studies at the Doha Institute for Graduate Studies, noted that if the Houthis were to shut down the Bab al-Mandab Strait, the Red Sea, and the Suez Canal, it would impact two major international shipping waterways, alongside the Strait of Hormuz. Al Jazeera's Nida Ibrahim reported from Ramallah that the opening of a new front in the war is likely to raise questions in Israel about 'the viability of the operations and the way the government is conducting its war'. She expects Israel to retaliate to this attack, as seen in previous instances when Yemen joined the battle.

Australian GPs are increasingly turning to AI scribes to record patient notes, with 40% now using the technology, according to a Royal Australian College of GPs (RACGP) online poll. This represents a significant increase from 22% in August 2024.AI tools, such as those offered by Australian company Heidi, record, transcribe, and summarize conversations between doctors and patients for medical notes. Dr. Max Mollenkopf, a GP based in Newcastle, emphasizes the importance of transparency with patients, stating, “We make a big effort to let patients know we are using AI, and give them the option to opt out.”While AI scribes can help relieve doctors' administrative burden, experts point to concerns about consent, privacy, and accuracy. Dr. Elizabeth Deveny, chief executive of the Consumer Health Forum, notes that not all practices are having explicit conversations about the tools with patients.Some GPs see AI scribes as a way to better connect with patients during consultations, allowing them to focus on the patient directly rather than typing notes. However, Dr. Caitlin Curtis, a University of Queensland researcher, warns that outsourcing note-keeping to AI may lead to doctors failing to retain and recall patient conversations.The RACGP president, Dr. Michael Wright, is optimistic about AI tools helping patients and GPs work more closely together, but emphasizes the need for patient consent and verification of AI output. Heidi co-founder Dr. Tom Kelly assures that data is processed securely and not used to train the AI or sold to others.

Recent headlines suggesting a Christian revival in Britain, based on a YouGov survey claiming increasing church attendance, have been dramatically undermined by the revelation that the data was fraudulent and subsequently withdrawn. This incident has sparked serious concerns about the integrity of polling data in an era of advancing artificial intelligence.The Bible Society's 2024 report, which claimed church attendance was rising particularly among young people, has become a case study in how AI-generated bogus responses are infesting online surveys. Researchers warn that this vulnerability extends beyond religious statistics to potentially distort our understanding of broader social trends.David Voas, a quantitative social scientist at University College London, emphasized the difficulty of correcting such misinformation once it spreads. "The amount of effort required to correct it is an order of magnitude higher than the effort needed to disseminate it in the first place," he stated, noting that this problem affects polling companies beyond just YouGov.The growth of AI has exacerbated this issue, according to Sean Westwood, an associate professor at Dartmouth College. "The assumption with survey research – that someone gives coherent, logical answers, they're a real person – that assumption is now broken," he explained. Westwood warned that AI models pose an existential threat to our understanding of society.Westwood detailed how AI can be weaponized: "A single sentence of instruction is enough to systematically bias its answers on political polls or geopolitical questions, while keeping its demographic profile intact so the manipulation is invisible to standard screening." Even without explicit instructions to cheat, AI can identify what a researcher is testing and produce data that confirms the hypothesis.The problem is particularly acute with surveys targeting younger demographics. Courtney Kennedy, vice-president of methods and innovation at Pew Research Center, noted that "bogus respondents tend to respond in the affirmative, no matter what is asked" – a positivity bias that inflates estimates. Younger respondents are also more likely to be misrepresented by fraudulent participants.As AI technology rapidly evolves, researchers face a constant challenge. "A researcher might design a clever new trap that catches today's models, but model development moves so fast that the fix is likely obsolete within months," Westwood cautioned.In response, YouGov has implemented detection methods including identity checks, device fingerprinting, and real-time threat scoring. However, the incident serves as a stark reminder of the vulnerabilities in modern polling systems as AI continues to advance.

The growing influence of political deepfakes is a pressing concern, as AI-generated content becomes increasingly sophisticated and accessible. Online content creators are not only building fake images and videos of prominent public figures but also fabricating people and using them in military contexts, which can make them money and serve as effective propaganda.According to experts, some of these online avatars are sexualized images of women wearing camouflage garb that have generated a significant audience and helped create an idealized image of political figures like Donald Trump, even if the viewer knows the content is not real. Daniel Schiff, an assistant professor of technology policy at Purdue University, notes that "we are blending the lines between political cartoons and reality," and that "a lot of people feel like these images or videos or the stories they convey, feel true."The amount of political deepfakes has increased dramatically in recent years, with over 1,000 English language social media posts featuring fake images or videos of prominent political figures and politically important social issues and events cataloged by the Governance and Responsible AI Lab (Grail) since the start of 2025. In contrast, the organization recorded 1,344 such incidents in the previous eight years combined.The uptick is largely due to improvements in generative AI technology, which has made it "trivially easy to generate a scene that looks pretty realistic and to place real individuals into scenes," according to Sam Gregory, executive director of Witness. The fake avatars, which mimic real ordinary people rather than known figures, are a different matter again.Researchers worry that things will only get worse, with the technology used to build AI-generated content like Jessica Foster potentially being used to produce "AI swarms" capable of "coordinating autonomously, infiltrating communities, and fabricating consensus efficiently." However, humans can still stop malicious actors from using AI to destabilize society by implementing technical standards for content provenance and authenticity and ensuring that technology companies label AI-generated content.
