Caster Semenya, the South African two-time Olympic 800m champion, has expressed strong disapproval of the International Olympic Committee's (IOC) decision to reinstate sex verification tests for the 2028 Los Angeles Games. Semenya, who has been a symbol of the struggle for hyperandrogenic athletes, described the move as 'a disrespect for women'.The IOC's new policy, announced on Thursday, limits eligibility for female category events to biological females, determined through a one-time SRY gene screening. This move effectively bans transgender athletes and a large number of intersex athletes from women's sports.Semenya, who has male XY chromosomes, is a well-known athlete with a difference in sex development (DSD). She has been a vocal advocate for the rights of athletes like herself, who are often subjected to sex verification tests and scrutiny.The IOC's decision has been met with criticism from Semenya and others, who argue that such tests are ineffective and discriminatory. Semenya stated, 'For you as a woman, why will you be tested to prove that you fit? You know, it's like now we need to prove that we are worthy as women to take part in sports. That's a disrespect for women.'The new policy is set to be implemented starting with the 2028 Olympics, and will be carried out through a saliva sample, cheek swab, or blood sample. This move has sparked controversy, with many arguing that it undermines the rights and dignity of transgender and intersex athletes.

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.

Kimi Antonelli, driving for Mercedes, dominated the Japanese Grand Prix to become the youngest driver to lead the Formula One world championship at just 19 years, six months, and 28 days old. Antonelli's victory was marked by a confident drive, where he overcame a difficult start to secure a second consecutive win. He started from pole but dropped to sixth at the start, only to regain the lead after a well-timed safety car period gave him a free pit stop. Oscar Piastri of McLaren finished second, 13.722 seconds behind, with Charles Leclerc of Ferrari taking third place. Meanwhile, George Russell, Antonelli's teammate, had a challenging race, finishing fourth but now trails Antonelli by nine points in the championship standings. The race was not without incident; a major crash involving Oliver Bearman resulted in a safety car deployment, which proved pivotal in Antonelli's victory. Bearman, who was lucky to escape uninjured, suffered a 50G impact and was taken to the medical centre with a right knee contusion. Antonelli's performance not only secured his second win of the season but also marked a significant milestone in his career, as he broke Lewis Hamilton's record as the youngest driver to lead the championship since 2007.

The UK vape industry is sounding the alarm about the proliferation of fake vapes on the market, which can pose serious health risks to users. These counterfeit devices are often sold in high street shops and can look identical to legitimate products, making them difficult to spot.According to the UK Vaping Industry Association (UKVIA), around 5m illegal devices have been seized over the last three years, with a street value of £39m. These devices often lack safety features, such as circuit protection to prevent overheating, which can cause them to catch fire.John Dunne, head of the UKVIA, warns that fake vapes may cause damage to people's health as they have not undergone the same testing regime as legal devices. 'Where the packaging might look similar and the product itself may look similar, these companies may not have the same safety features built into the device, because the copycats tend to try and make the product as cheap as possible,' he says.So, how can you spot a fake vape? One of the key telltale signs is if the box does not have a UK distributor's address on it. Other signs include poor-quality packaging with low-resolution photos or labels, and missing nicotine warnings and ingredient lists. The device name or labelling may also be written in a foreign language.If you suspect that you have bought a fake vape, you can file a report through the UKVIA or contact your local Trading Standards office. You can also check whether a brand has been registered with the MHRA through its website.

Morocco's national football team has moved on from the controversy surrounding their award of the Africa Cup of Nations (AFCON) title, despite Senegal's ongoing appeals to the Confederation of African Football (CAF) and the Court of Arbitration for Sport (CAS). The Atlas Lions lost 1-0 to Senegal in the January final but were awarded a 3-0 victory last week due to several Senegalese players leaving the pitch in protest at a penalty. In their first match since the final and the controversial decision, Morocco drew 1-1 against Ecuador in a friendly in Madrid, under the guidance of new coach Mohamed Ouahbi. Morocco goalkeeper Yassine Bounou emphasized the team's focus on future matches, stating, 'We're focused on what's to come and not getting into that [topic].' The team's supporters also expressed their satisfaction with the decision, with one fan saying, 'If someone says there are regulations, you have to follow them.' With 25 matches unbeaten, Morocco is looking forward to the 2026 World Cup, where they will face record five-time World Cup winners Brazil in their first game. The team's coach, Ouahbi, highlighted the strength of his team, saying, 'I don't talk in terms of weaknesses. We're a top-level team – the Ecuadorian coach reminded us of that.'

Iranian President Masoud Pezeshkian has issued a stern warning to neighboring countries, urging them not to allow the US and Israel to use their territory to launch attacks against Iran. In a post on X, Pezeshkian emphasized that Iran does not initiate preemptive attacks but will strongly retaliate if its infrastructure or economic centers are targeted. “To the countries of the region: If you want development and security, don’t let our enemies run the war from your lands,” Pezeshkian stated. This message is part of a broader effort by Iran to prevent the escalation of the ongoing conflict with the US and Israel. The conflict began on February 28, when the US and Israel launched air strikes across Iran, resulting in the death of Supreme Leader Ayatollah Ali Khamenei. Since then, the situation has shown no signs of de-escalation, with Israel announcing daily strikes on Iran and Tehran continuing to target its arch-rival and countries hosting US military assets. In recent developments, several Gulf states have been targeted in attacks. In Kuwait, multiple drone attacks damaged the international airport's radar system, while in Abu Dhabi, strikes caused debris to fall near the Khalifa Economic Zone, injuring six people. Iran's military claimed to have struck a Ukrainian anti-drone system depot in Dubai, which it alleged supported US forces. Iranian Foreign Minister Abbas Araghchi also urged regional countries to distance themselves from the US, reiterating Iran's stance that it will not tolerate the use of neighboring territories for hostile actions. The conflict has resulted in significant disruptions across the region, with at least 15 American soldiers wounded in an Iranian attack on a Saudi airbase on Friday. The situation remains volatile, with alarm sirens activated in Bahrain and Saudi Arabia's defense ministry reporting ballistic missile and drone attacks, all of which were allegedly shot down.
