Mexico's Navy and the United States Coast Guard are conducting a search for two missing sailboats that were part of a humanitarian convoy to Cuba. The vessels, which departed from Isla Mujeres in Mexico on March 20, were expected to arrive in Cuba on Tuesday or Wednesday of this week. Nine people were on board the two sailboats, which were organised by the Nuesta America Convoy. The convoy has accused the US government of 'strangling' Cuba by cutting off fuel, flights, and critical supplies for survival. Cuban President Miguel Diaz-Canel expressed anxiety about the fate of the boats, stating that Cuba is doing everything possible to search for and rescue those on board. The US Coast Guard initially reported that the boats had been located, but later retracted the statement. Search efforts are currently being led by Cuba and Mexico, but the US Coast Guard has stated that it is prepared to provide support if requested. The convoy comes in response to worsening humanitarian conditions in Cuba, which has largely been cut off from foreign oil supplies since January. The US has imposed an oil blockade on Cuba, which has led to a humanitarian crisis on the island. The blockade was tightened by the Trump administration, which has signalled its desire for regime change in Cuba. Mexico and other countries have increased their humanitarian aid to Cuba amid the crisis, with Mexican President Claudia Sheinbaum sending ships laden with supplies. The Nuestra America Convoy initially sent several ships to Cuba last Friday, with one arriving safely in Havana on Tuesday with 14 tonnes of food and medicine.

In the hallway at the Portuguese federation's base in Oeiras near Lisbon, Roberto Martínez stands with arms outstretched, embodying the warmth of welcome that has defined his coaching career. Seventy-five days before the World Cup begins, the man whose favorite goal was against Scunthorpe at Springfield Park now leads one of football's most formidable nations, with matches against Mexico and the United States serving as final preparation for the tournament.Martínez's journey to this moment defied conventional expectations. Arriving in England in 1995 as a 21-year-old unknown who didn't speak English, he recalls the cultural shock: 'You've spent your whole life learning you have to look after the ball, then you get there and the first thing they say is: 'Second ball'.' The Spanish midfielder, who would later be dubbed one of the 'Three Amigos' at Wigan, embraced the challenge with an attitude that has defined his career: 'Why not?'From his humble beginnings at Wigan, where he helped win the Third Division and Football League Trophy, Martínez has carved an extraordinary path through football. His coaching career took him through Swansea, Belgium—where he led the team to the world's No. 1 ranking—and now Portugal, where he has inherited a squad filled with exceptional talent. 'Portugal is a football school,' he explains, 'Ten million people and yet they fill the world's best dressing rooms.'Central to Portugal's World Cup aspirations is Cristiano Ronaldo, the legendary forward who has given 21 years to the national team. Martínez dismisses the notion that Ronaldo's pursuit of 1,000 career goals defines his motivation, instead emphasizing the 40-year-old's unwavering commitment: 'Cristiano's attitude is always: 'I'm here for the national team, whatever you need.' The coach reveals that despite a current hamstring injury, Ronaldo's absence is merely a two-week pause before his return to action.Portugal enters the World Cup as one of the favorites, with a squad boasting captains from Manchester United, Porto, Manchester City, and four key players from European champions Paris Saint-Germain. 'Winning the Nations League was very good for us,' Martínez notes, referring to their victory against Spain, the world's No. 1 team and European champions. 'I wouldn't say there's an anxiety in Portugal to win the World Cup; I would say it's excitement, hope.'The coach's meticulous preparation extends to every detail, including playing at altitude in closed stadiums to simulate World Cup conditions. His selection process reflects both compassion and pragmatism: 'I'll choose a list of 26 and four others who know they are on standby.' This approach, he believes, creates a more positive environment when injuries occur.Martínez acknowledges the unique challenges of a 48-team World Cup spanning 50 days, noting: 'No scientific study would deny a human is changed by that.' Yet he remains optimistic, drawing inspiration from Portugal's football history and the numerological significance of 2026—sixty years since Eusébio's World Cup performance. 'It's all sixes. Let's dream. Why not?' he concludes, embodying the philosophy that has taken him from Spanish unknown to Portugal's World Cup dreamer.

Lachie Kennedy has once again outshone his fellow Queenslander, Gout Gout, in a captivating display of athleticism at the Maurie Plant Meet on Saturday. The 200m Peter Norman Memorial race saw Kennedy claim victory with a time of 20.38 seconds, despite challenging weather conditions.Gout Gout, just 18 years old and four years Kennedy's junior, put up a formidable fight but ultimately finished second, five hundredths of a second behind the winner. The young athlete expressed his determination to improve, stating, 'Today he got the win, but next time I’ll be better for sure.'Kennedy's win was a testament to his skill and strategy, as he managed to hold off Gout's late surge. The Queenslander had already impressed in the 100m event earlier in the evening, securing a time of 10.03 seconds despite blustery conditions.The rivalry between Kennedy and Gout has become a highlight of the Australian athletics season, drawing comparisons to iconic sporting duels. With the Brisbane 2032 Olympics on the horizon, their formative battles are set to captivate audiences in the lead-up to the Games.The event, attended by nearly 9,000 fans at Lakeside Stadium, showcased not only the prowess of Kennedy and Gout but also remarkable performances from other athletes. Cam Myers recorded the fastest 1500m time in Australia, while Claudia Hollingsworth and Nina Kennedy also delivered standout results in their respective events.

Malaysian Prime Minister Anwar Ibrahim revealed in a televised address that Iran's President Masoud Pezeshkian has allowed Malaysian vessels to pass through the Strait of Hormuz with 'early clearance'. This development comes as the global energy market faces significant disruptions due to the ongoing conflict between Iran, the United States, and Israel.Anwar expressed gratitude to Pezeshkian for the clearance, which will enable Malaysian oil tankers and their crews to continue their journey home. While he did not specify the number of vessels cleared or the conditions for safe passage, he emphasized that Malaysia is working to secure the release of its ships and personnel.The Strait of Hormuz is a vital waterway, facilitating about one-fifth of global oil and liquefied natural gas (LNG) supplies. Iran has claimed the right to control the strait and has been responsible for several attacks on commercial vessels in the region. Despite Iran's assertion that the strait is open to non-aligned ships, there have been reports of Iranian authorities demanding tolls of up to $2 million for safe passage.Malaysia, a net energy exporter and one of the world's top LNG suppliers, imports nearly 70% of its crude oil from the Gulf region. Anwar noted that while Malaysia is better positioned than other nations due to its state-run oil and gas company Petronas, the country will still face impacts from the energy supply disruptions. To mitigate these effects, the government plans to implement fuel conservation measures, including reducing subsidized petrol quotas and encouraging civil servants to work from home.Anwar warned that food, fertilizer, and oil prices are likely to rise due to the disruptions. He emphasized that Malaysia is taking steps to address these challenges, adding that some countries are experiencing far worse impacts than Malaysia.

Iran has formally responded to the US's proposal to end the nearly month-long war, asserting its 'natural and legal right' over the Strait of Hormuz. The Islamic Revolutionary Guard Corps-affiliated Tasnim news agency reported that Iran had sent its official response on Wednesday night and was awaiting a response.The Iranian response appears to contradict US President Donald Trump's claim that Tehran was 'begging to make a deal'. Instead, Iran has laid out conditions that signal a continued hardening of its position, including an end to 'aggressive acts of assassination', compensation and war reparations, measures to ensure 'war does not recur', and an end to hostilities from 'all resistance groups that took part in this battle throughout the region'.US special envoy Steve Witkoff claimed on Thursday that Tehran was seeking an 'off-ramp', with signs that Iran had realised there was no alternative to negotiation. However, the source cited in Tasnim's report slammed the US proposal, claiming that Washington sought to 'deceive the world' by presenting a peaceful image while preparing for 'ground invasion'.Trump posted on Truth Social that he would pause attacks on Iran's energy infrastructure for 10 days until April 6, claiming Tehran requested the move amid 'ongoing' talks that were 'going very well'. He also claimed that Iran was 'begging to make a deal', saying 'We are absolutely obliterating Iran' and that Iranians were 'lousy fighters, but great negotiators'. The economic and humanitarian toll of the conflict continues to mount, with Iran effectively blocking the Strait of Hormuz, leading to fuel shortages worldwide.

Saudi Arabia has urged the US to ramp up attacks on Iran, a Saudi intelligence source has confirmed, while it is weighing a decision on whether to join the fight directly. The Saudi source confirmed reporting that the kingdom’s de facto leader, Crown Prince Mohammed bin Salman, has urged Donald Trump not to cut short his war against Iran, and that the US-Israeli campaign represented a “historic opportunity” to remake the Middle East.The intelligence source said Riyadh was not just calling for the military campaign to be continued, but to be intensified. Trump appeared to confirm the report about the crown prince’s role, telling journalists on Tuesday: “Yeah, he’s a warrior. He’s fighting with us.”There are no reports of active Saudi military involvement in the nearly four-week-old war so far, but a Saudi political analyst said the kingdom was likely to take that step if current peace efforts led by Pakistan failed.“What matters now is Iran’s decision,” Mohammed Alhamed, a Saudi geopolitical analyst, said. “If Iran engages seriously, there is still a path to contain escalation. If it rejects the conditions and continues its attacks, the threshold for Saudi action will be crossed.”Alhamed added that Saudi Arabia “is not reacting impulsively”.“It is calibrating its response and preparing for a scenario where escalation, if it happens, will be deliberate and decisive,” he said, adding that Saudi Arabia “has not been pushing for war.”“It has been trying to avoid being drawn into it, while keeping all options on the table,” he said.Saudi Arabia has come under Iranian drone attack, as part of Tehran’s response to the US-Israeli attack on 28 February. One drone strike a week ago hit an oil refinery in Yanbu on Saudi Red Sea coast.The attack on Yanbu signalled an Iranian warning that it could also threaten that economic lifeline.“I believe that Saudi Arabia still maintains cautious neutrality in the Iran-Israel-US war,” Hesham Alghannam, a Saudi defence expert told Agence France-Presse. But he added: “If the Houthis strike Saudi assets, Riyadh may shift toward defensive coalition support or limited retaliation.”The crown prince solidified his hold on power by cultivating a close relationship with Trump, but will now have to rethink Saudi reliance on the US for its security, observers have argued.“MBS [Mohammed bin Salman] has lost the bet on all his investments over the last several years,” Ellie Geranmayeh, senior policy fellow at the European Council on Foreign Relations said. “He financially invested in Trump and Trump’s family and his corporation and his White House, but at the end of the day the views of the Saudis and of the whole Gulf have been sidelined by the wishes of Benjamin Netanyahu.”

Walking into Scisters Salon & Apothecary in southern California reveals what's immediately absent: no wall of plastic bottles, no chemical tang, and minimal waste. The salon's shelves feature large refill containers of shampoo and conditioner, houseplants adorn the space, and hair clippings are composted. The only trash can is a small basket mostly collecting clients' personal items, creating an environment that co-owner Melissa Parker notes clients immediately comment on: 'It smells good in here.' That never happens in a conventional salon.Opened 15 years ago by Parker and Easton Bajsec in La Mesa near San Diego, Scisters has evolved into one of the region's most prominent low-waste salons, diverting up to 99% of its refuse from landfills. Their business transformation addresses a significant industry problem: the beauty sector generates substantial waste, with North American salons sending an estimated 63,000lbs of hair to landfills daily, plus hundreds of tons of used foil and leftover hair dyes.The turning point came when Bajsec watched a documentary about the zero-waste movement while Parker developed health problems linked to prolonged exposure to salon chemicals. Studies have found that hairdressers' exposure to harmful chemicals such as formaldehyde, ammonia and sulfates puts them at higher risk of asthma, skin conditions, reproductive illnesses and cancer. Rather than leave the industry, they transformed their business.They eliminated perms due to formaldehyde exposure and moved away from big-name products despite green marketing claims. When existing alternatives didn't meet their standards for performance, ingredient transparency and waste reduction, they created their own line. Element, launched in 2019, is made in a California lab and sold in refillable glass and aluminum containers, featuring recognizable ingredients like organic aloe, wheat protein and castor oil.The salon's waste reduction strategies extend beyond product packaging. They implemented hair composting, foil recycling, and replaced waxing with sugaring—a compostable hair-removal technique. They switched to LED lighting, installed water-efficient showerheads, and use washable cloths instead of paper towels. Though they still offer hair bleaching (which releases ammonia), they mitigate risks with industrial air filtration and air-purifying plants.Bajsec acknowledges that 100% zero waste is impossible due to regulatory constraints on reusable gloves and plastic pump tops. The salon ships its minimal plastic waste to Green Circle Salons for specialized processing, paying $200 per box. Despite this cost, Parker notes the overall approach has been financially beneficial: 'Overall, it's actually less expensive. We're not outsourcing to other beauty brands. We're mindful about systems.'Their commitment to sustainability proved critical during the COVID-19 pandemic. When mandatory closures threatened their survival, they pivoted to refill sales, meeting clients in the parking lot. This refill model kept revenue flowing, allowing them to pay full rent while many neighboring tenants struggled. 'Going green has been the greatest thing we've done for our business financially,' Parker says. 'We accidentally created a point of differentiation.'Denise Baden, a professor of sustainable business at the University of Southampton, confirms that eco-friendly practices often reduce costs. 'It's a misunderstanding that to be eco-friendly, you have to spend more money. In fact, usually, it's the reverse,' she notes, adding that hairdressers are uniquely positioned to influence their communities.Now, Parker and Bajsec are helping other salons adopt similar practices through speaking engagements and an online guide. 'We get calls from other salons all the time,' Bajsec says. 'It's not sustainable if we're the only ones doing it.'

A recent study conducted by researchers at Adelaide University has revealed that sperm in microgravity environments become disoriented and struggle to navigate through a simulated female reproductive tract. This finding has significant implications for the future of human reproduction in space, particularly as plans for lunar and Mars settlements gain momentum. The researchers used a machine to mimic microgravity, similar to the conditions experienced by astronauts on the International Space Station. They found that sperm tumble around like untethered astronauts, unable to determine their direction. This disorientation resulted in a 40% reduction in the number of microgravity-exposed human sperm that successfully navigated the maze compared to the control group. The study, published in the journal Communications Biology, highlights the challenges of reproduction in space. Dr. Nicole McPherson, the lead researcher, noted that understanding the effects of microgravity on sperm navigation is crucial for the success of future space missions. The study also found that adding progesterone helped overcome the sperm's disorientation, suggesting a potential solution for improving fertility in space. The research has broader implications for both space exploration and earthly reproductive science. As NASA's Artemis mission and private companies like SpaceX plan for human habitats on the moon and Mars, understanding the effects of microgravity on reproduction becomes increasingly important. The study's findings also contribute to the ongoing discussion about the feasibility of human settlements on Mars and the need for sustainable reproductive technologies. The Adelaide researchers collaborated with the university's Andy Thomas Centre for Space Resources to conduct the study. Their work builds on a history of research into reproduction in space, including NASA's 2018 mission to study the effects of weightlessness on human sperm. As space exploration advances, the need for further research into reproductive health in space becomes increasingly urgent.

The ongoing conflict between Iran and the US-Israel alliance has severely disrupted shipping through the Strait of Hormuz, a vital passage for about a fifth of the world's oil and gas supplies and a third of global fertilisers necessary for food production.Before the conflict, an average of 138 ships a day transited the strait. However, following the escalation, 100 vessels have exited the Gulf and only 40 have entered in the past month, according to Lloyd’s List Intelligence.Despite over 20 reported attacks on ships in the region, including near-misses and damage to vessels, some ships are still attempting to cross, with Iran permitting 'non-hostile vessels' to use a 'safe corridor' in its territorial waters. This route allows Iranian authorities to visually verify vessels and potentially demand payment for safe passage.The International Maritime Organization (IMO) has raised concerns about the 20,000 seafarers stranded in stressful conditions with dwindling supplies. Over 30 countries have agreed to work together to safeguard the strait, with the UK offering to host an international security summit to devise a plan to reopen it.
