The Breakthrough in Breast Cancer TreatmentA landmark international study has revealed that millions of women with breast cancer could safely skip chemotherapy thanks to a genomic test that determines who needs the treatment and who doesn't. The randomised trial specifically examined whether the test could identify patients who would not benefit from chemotherapy, allowing them to avoid the potentially debilitating treatment without compromising their outcomes.The Scientific Evidence Behind the TestThe results of the Optima trial, which will be presented at the American Society of Clinical Oncology's annual meeting, are being hailed by experts as gamechanging. The five-year cancer-free survival rate was 93.7% in the group that skipped chemotherapy, which was statistically non-inferior to the 94.9% rate in patients randomly assigned to receive chemotherapy.The Prosigna genomic test analyzes the activity of 50 specific genes in tumor tissue to determine the molecular subtype and develops a risk of recurrence score to help doctors decide if chemotherapy is necessary. This precision medicine approach allows for personalized treatment decisions based on the unique characteristics of each patient's cancer.A Patient's Journey to Avoiding ChemotherapyKaren Bonham, a speech and language therapist from Swansea in Wales, was one of 4,429 patients with breast cancer recruited to the trial from countries including the UK, Norway, Sweden, Australia, New Zealand and Thailand. Diagnosed with cancer in 2017 at the age of 55 after routine breast screening, Bonham described the news as shocking."It certainly propels you into a world of uncertainty. Life priorities realign – you simply want to survive," she said. Dreading chemotherapy, she agreed to join the Optima trial after undergoing surgery. She was only days away from starting treatment and had already cut her hair short when the results came back in September 2017.While taking a walk on a Welsh beach, Bonham received a phone call from her hospital informing her she had been allocated to the group of patients that would not be having chemotherapy. "How to describe the initial feeling? Immense relief? Like Christmas? Certainly a mixture of the two," she said.The Future of Personalized Cancer CareToday, Bonham, now 64, retired and living in Cardiff, is free of cancer, healthy and shows no signs of the disease coming back. "It is coming up to nine years since my diagnosis," she said. "I am mindful of my diagnosis, alert to potential changes in my body but do not feel defined by [it]. I walk, enjoy yoga and live well."While not every woman with breast cancer will be able to skip chemotherapy—the treatment remains necessary and important for many—the trial results suggest that genomic testing can safely identify those who can avoid it. This approach represents a significant shift toward personalized medicine in oncology, reducing unnecessary treatment and its associated side effects while maintaining excellent outcomes."I hope that the trial will bring positive patient outcomes to many," Bonham said, reflecting on the potential impact of this research on future breast cancer patients.

Lead: A Milestone Reflection on Climate ActionIn its 250th edition, the Guardian's Down to Earth newsletter pauses to assess how the world's fight against climate change has unfolded since the high‑water mark of Cop26 in Glasgow, 2021.Looking Back: Cop26’s Promise and the Five‑Year Journey2021‑2022: Nations pledged to limit warming to 1.5°C, set net‑zero targets and pledged to phase out coal.2022‑2023: The Russian invasion of Ukraine and the Iran‑oil conflict drove crude prices above $100 /barrel, exposing fossil‑fuel vulnerabilities.2024‑2025: Populist governments rolled back environmental regulations, while renewable technology became cheaper and more widespread.Numbers That Matter: Public Awareness and Emissions GapsThe “Covering Climate Now” survey found that 80‑89 % of the global public recognise the climate threat and demand government action.Current national plans still point to a projected warming of about 2.8 °C, well above the agreed target.Renewable energy costs have fallen by roughly 70 % since 2020, making clean power “cheap, widely available and overwhelmingly popular.”Why the Momentum Slowed: Geopolitics, Economics and PopulismWar‑driven spikes in oil prices, the re‑election of climate‑skeptical leaders and the rise of populist rhetoric have eroded the optimism that surrounded Cop26, pushing many countries to backtrack on commitments.What Lies Ahead: Hopeful Trends and Persistent ChallengesDespite setbacks, advances in clean‑tech, growing public pressure and emerging green‑economy initiatives suggest a pathway forward, but the intertwined climate‑biodiversity‑economy crises demand coordinated global action.

The Lead Kyrgyzstan, a mountainous, landlocked Central Asian nation, has historically been one of the region's poorest economies. However, its fortunes changed four years ago when it emerged as a key hub for goods bypassing embargoes imposed on Russia. Kyrgyzstan's Growing Trade with Russia From 2021 to 2022, the annual value of Kyrgyzstan's exports to Russia leaped from $393m to $1.07bn, including products such as luxury cars and microchips. Some of these products, like microchips, are known as 'dual-use,' meaning they are imported to third countries like Kyrgyzstan as civilian goods and then re-exported to Russia, where they may be utilized in military hardware. The Data Analysis 2021: $393m in exports to Russia 2022: $1.07bn in exports to Russia The Impact Analysis The recent shutdown of companies suspected of aiding Russia is a significant move by Kyrgyzstan to avoid being sanctioned itself. This decision comes after the European Union imposed an embargo on certain electronic goods to Kyrgyzstan for rerouting such products to Russia. The country's close relationship with Russia, including mutual defense agreements and Russia's significant influence, makes this move crucial. The Prediction As Kyrgyzstan navigates its relationships with Russia, the European Union, and other global players, it is likely to face increased pressure to comply with international sanctions. The country's economic partnership with China, which borders Kyrgyzstan to the east, may also play a significant role in shaping its future. With growing discontent among its intellectual elites, activists, and younger generations, Kyrgyzstan's stance on Russia's influence may continue to evolve.

The Journey to Rogun: A Nation's AmbitionThe road to Rogun Dam from Tajikistan's capital Dushanbe winds through rocky hills and small villages, offering a glimpse into the challenging terrain where this monumental project is taking shape. For Tajikistan, a nation familiar with winter power outages and harsh geography, the Rogun Dam represents more than just infrastructure—it's a promise of energy security and economic independence.The Engineering Marvel: Taming the Vakhsh RiverThe $5 billion Rogun project, originally launched in the mid-1970s to address Tajikistan's chronic energy shortages, has been described by President Emomali Rahmon as a matter of 'life or death.' The dam is being constructed on extremely difficult terrain, requiring complex engineering solutions including access roads, excavation, transportation challenges, and river control systems.A Subterranean Network: The Hidden InfrastructureRogun is not merely a concrete wall holding back water but an entire network of tunnels, diversions, canals, and facilities beneath and around the mountain. The project includes hydraulic tunnels ranging from 1,100 to 1,500 meters in length and an underground power station housing six units designed to harness the power of the Vakhsh River.The Power Generation: From Water to ElectricityAt the heart of the project are massive turbines that will convert the movement of water into electricity. Once completed, the dam will stand 335 meters high, making it one of the tallest in the world, with a power plant capable of producing approximately 3,600 megawatts of electricity—enough to potentially transform Tajikistan's energy landscape and allow for power exports to neighboring countries.The National Dream: Project of the CenturyFor Tajikistan, Rogun has become the 'Project of the Century'—a gamble on the nation's geography to turn adversity into strength. While the project offers tremendous potential benefits, it also carries significant risks requiring massive funding, meticulous management, stringent safety guarantees, and careful balance with downstream countries in the sensitive regional water system.

The Ongoing Rescue Efforts in Laos Rescuers are racing against time to save two people still trapped in a flooded cave in Laos, after five others were rescued from the site. The rescue operation, which involves teams from Laos, Thailand, and several other countries, has been complicated by heavy rains that have threatened to delay the search. Challenges in the Rescue Operation Finnish diver Mikko Paasi, one of the first international rescuers to arrive at the site, reported that rains on Sunday had filled the cave up to the second chamber. This has prevented divers from entering until pumps can lower the water level. A drainage pump also broke, making the situation even more difficult, according to fellow diver Yoshitaka Isaji of Japan. The Situation Inside the Cave The cave, located in a remote mountainous area of central Xaysomboun province, was entered by seven people last week in search of valuable minerals such as gold. A flash flood blocked their way out, trapping them. One person escaped and alerted the authorities. The five rescued men were found in the fifth chamber of the cave system, which has five chambers. The Rescue Plan Rescue teams have received "substantial" information on the cave system from the five men who were rescued earlier. Based on this information, rescuers are hopeful that today's mission will locate both remaining victims. Malaysian diver Lee Kian Lie reported that the survivors provided details about the deeper part of the cave, which will aid in the search for the two missing individuals. The Future Outlook The rescue operation is expected to continue with the help of pumps to lower the water level in the cave. Rescuers are navigating more than 200m into the cave and are focused on finding the two missing individuals. The situation remains challenging due to the heavy rains and broken drainage pump, but the rescue teams are working tirelessly to save the trapped individuals.

The Call for Tax Cuts Wes Streeting has called for national insurance tax cuts for businesses, and for the government to drill for oil and gas in the North Sea. The former health secretary and Labour leadership candidate told the Sunday Times there should be a “targeted reduction” of employers’ national insurance contribution as a way to “actively incentivise” hiring, particularly of young people. The Impact of National Insurance Rate Increase In 2024, the rate of national insurance paid by employers was increased from 13.8% on each employee’s salary to 15%. The starting threshold it applied to was lowered from £9,100 to £5,000. The measure aimed to raise £25bn a year, but businesses said it disincentivised hiring lower-paid and part-time staff. Youth Unemployment Concerns A report this week by the former cabinet minister Alan Milburn said a lack of hospitality jobs was contributing to high youth unemployment in Britain. It pointed to a halving of vacancies in the hospitality industry over the past four years alone. Analysis shows Britain has the third-highest rate of 16- to 24-year-olds who are not earning or learning among rich European countries. The Government's Response Pat McFadden, the work and pensions secretary, suggested he disagreed with this view. Speaking on Sky News on Sunday morning, he defended the government’s record, saying that businesses already did not have to pay employers’ national insurance for workers under 21. The Future of North Sea Drilling There has been a debate within Labour about whether to grant drilling consents for the giant oil and gas fields Rosebank and Jackdaw. Though there was a commitment not to give out any more licences for fossil fuels in Labour’s manifesto, there is a loophole that could be exploited; Rosebank and Jackdaw were given exploration licences by the previous Conservative government. They just need consent to drill. Ed Miliband's Decision Ed Miliband, the energy secretary, is due to make a decision on these oil and gas fields in coming weeks. He, along with the North Sea Transition Authority, have to decide whether the drilling would be consistent with the UK’s climate commitments.

The Lead: Unprecedented Cancer Treatment SuccessDoctors have hailed "unprecedented" trial results that show a triple-action cancer jab can eradicate entire tumours in patients. In an international trial spanning 11 countries, the injection was offered to patients whose cancer had spread or come back and whose disease had failed to respond to other treatments.The Breakthrough: Amivantamab's Triple-Action ApproachThe jab, called amivantamab, shrank the tumours of more than a third of patients, with dramatic changes seen within weeks. In 15 of them, doctors found the drug had melted away their tumours altogether.The smart jab targets cancer in three ways. It blocks both EGFR (epidermal growth factor receptor), a protein that helps tumours grow, and MET, a pathway that cancer cells often use to escape treatment. It also helps activate the immune system to attack the tumour.The Clinical Trial Data: Impressive Response RatesIn the trial, 102 patients with head and neck cancer, the world's sixth most common cancer, were given the jab. Tumours shrank or disappeared completely in 43 patients, including 28 whose tumours shrank significantly and 15 who saw them eradicated entirely.Patients receiving amivantamab lived for a median of 12.5 months overall after starting treatment, despite having a form of cancer with very poor outcomes, once standard treatments stop working.The Impact Analysis: New Hope for Treatment-Resistant CancersKevin Harrington, professor in biological cancer therapies at the Institute of Cancer Research, London (ICR), said: "These are unprecedentedly strong responses in patients whose disease has become resistant to both chemotherapy and immunotherapy. This is a group of patients for whom treatment options are extremely limited, so seeing this level of benefit is very striking."Researchers also highlighted that the trial focused on people with head and neck cancers that did not include those with human papillomavirus (HPV) positive oropharyngeal squamous cell carcinoma. That is particularly significant, they said, since head and neck cancers not caused by HPV are usually harder to treat, making progress in this group hugely important.The Patient Experience: Transforming Quality of LifeOne of the first patients to benefit was Carl Walsh, 56, who was diagnosed with tongue cancer in May 2024 and joined the OrigAMI-4 trial at the Royal Marsden in July 2025. "I was initially treated with both chemotherapy and immunotherapy, which unfortunately were not successful," he said. "At that point, I was recommended for the OrigAMI-4 trial. I'm now on my 17th cycle of treatment and I'm very pleased with the progress so far."Unlike many cancer treatments, amivantamab is given as a tiny jab under the skin rather than via an intravenous drip, making treatment quicker and more convenient for patients and much easier to deliver in outpatient clinics.The Future Outlook: Expanding Treatment ApplicationsThe results will be presented on Sunday in Chicago at the world's largest cancer conference, the annual meeting of the American Society of Clinical Oncology (Asco).Amivantamab, developed by Johnson & Johnson, is now being evaluated in about 60 clinical trials, primarily for lung cancer, but also for colorectal, brain and gastric cancers.Prof Kristian Helin, the chief executive of the ICR, said: "This study demonstrates how the development of new treatments through rigorous cancer research may lead to meaningful advances, even for patients with very limited treatment options. Achieving this level of tumour response and encouraging survival outcomes in such a challenging-to-treat group represents a significant step forward."
