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.'

US President Donald Trump has extended his deadline for Iran to open the Strait of Hormuz by 10 days to April 6, 2026. The decision comes as talks between the US and Iran are described as 'going very well'.In a social media post, Trump stated: 'As per Iranian Government request, please let this statement serve to represent that I am pausing the period of Energy Plant destruction by 10 Days to Monday, April 6, 2026, at 8 P.M., Eastern Time.'Trump also mentioned that despite 'erroneous statements to the contrary by the Fake News Media,' talks with Iran are ongoing and progressing well. He had previously urged Iranian leaders to negotiate an end to the near-month-long war or face further assassinations of senior officials.The conflict has resulted in significant escalation, with Israel conducting strikes on Iranian targets, including the killing of Alireza Tangsiri, the Revolutionary Guards' naval commander. Iran has retaliated with strikes across the Middle East, including in Tel Aviv, Modi'in, and Jerusalem.Trump has claimed victory in the war, stating, 'In a certain sense, we have already won.' He has also criticized NATO allies and described Iran as producing 'great negotiators' but 'lousy fighters.'The US and Israel have destroyed much of Iran's naval capabilities, but Tehran still possesses smaller boats capable of laying mines and launching anti-ship cruise missiles. These could render the Strait of Hormuz impassable to shipping.Iran's foreign minister, Abbas Araghchi, accused the US of 'double standards,' citing the US support for Israel's actions in Gaza while condemning Iran's defense in the Strait of Hormuz.The conflict has resulted in a significant death toll, with over 1,900 people killed in Iran and nearly 1,100 in Lebanon. The situation remains volatile, with fears of further escalation and potential ground invasion.

The UK government has announced a significant intervention in the country's industrial sector, investing £100m to reopen a carbon dioxide plant on Teesside. The Ensus plant, which was mothballed in September, will restart operations for an initial three-month period, with hopes that it could then remain open indefinitely.The decision to reopen the plant comes amid concerns that the war in Iran could trigger shortages of CO2, a gas that has various uses ranging from carbonating drinks and keeping food fresh to medical procedures and the sedating of animals for slaughter. The plant's reopening is expected to bolster production of CO2 and help ensure the resilience of supply chains.The Business Secretary, Peter Kyle, approved the reopening of the plant, stating that the government would 'always do what's needed to ensure resilience and protect British businesses from the worst impacts of global uncertainty.' The move is part of wider government efforts to ensure the UK maintains access to critical industrial resources during global supply shocks.The UK's food and drink industry faced a CO2 crisis in 2021, after the easing of pandemic restrictions sent the price of wholesale gas soaring, pushing up the manufacturing costs of fertiliser production, which also produces the gas as a byproduct. The crisis resulted in the government providing a temporary bailout to the American company CF Fertilisers to help restart CO2 production at its Teesside factory.The Ensus plant has had operations on Teesside since 2010, using distillation and fermentation to convert wheat into bioethanol. CO2 is a byproduct of this process, as well as high-protein animal feed. The company, which is headquartered in Middlesbrough, employs about 100 people.

The World Health Organization (WHO) has issued a dire warning about a health crisis unfolding in real time across the Middle East, emphasizing the urgent need for a complete cessation of hostilities to mitigate the humanitarian catastrophe.Dr. Hanan Balkhy, the WHO's regional director for the Eastern Mediterranean, stressed that hospitals and healthcare facilities must be treated as safe havens to protect patients and healthcare workers. The region, encompassing 22 countries and territories including Iran, Gulf states, Gaza, Sudan, Afghanistan, and Pakistan, is facing severe disruptions in healthcare services due to the ongoing conflicts.The violence has resulted in significant loss of life and displacement, with over 1,000 people killed in Lebanon, 1,500 in Iran, and 16 in Israel, alongside reports of numerous deaths in the West Bank and Gulf Arab states. Moreover, 3.2 million people have been displaced in Iran and over 1 million in Lebanon within a month, exacerbating the crisis.Balkhy expressed deep concern about the long-term impacts on maternal mortality, mental health, and the plight of orphaned children left without education. The WHO has verified dozens of attacks on healthcare facilities in Lebanon, Iran, and Israel since the conflict began, including a recent attack on a hospital in Sudan that killed at least 70 people.The organization is also preparing for potential attacks on nuclear sites and water desalination plants, which could have catastrophic health repercussions. Balkhy urged for a significant de-escalation or a permanent pause in hostilities to prevent further humanitarian disaster.

Solar panel sales have surged dramatically since the onset of the Iran war, according to Octopus Energy, with British households increasingly opting for larger rooftop installations to achieve energy independence.The company reported a 54% increase in sales this month compared to the same period last month, marking a significant shift in consumer behavior amid global energy uncertainty.Rebecca Dibb-Simkin, Octopus Energy's chief product officer, observed: "We are seeing a massive shift as people stop just asking and start acting. British families are tired of being held hostage by global fossil fuel prices. By switching to solar and heat pumps, they are becoming their own power stations, locking in low costs and protecting their wallets for the long term."Octopus noted that many customers are choosing "supersize" systems with 12 panels instead of the typical 10-panel arrays. Additionally, heat pump sales have increased by more than 50%, while electric vehicle charger systems have seen a 20% rise in sales.Greg Jackson, Octopus Energy's chief executive, described a "huge jolt" in solar sales compared to February. On March 17, the company reported a 27% increase in solar sales inquiries since the start of the Iran war.Good Energy, another green electricity supplier, confirmed this trend, reporting a doubling of interest in solar panels over the past three months.Nigel Pocklington, Good Energy's chief executive, emphasized: "The most effective way to bring bills down over the long term is to double down on renewables, alongside storage and flexibility, so more of our power comes from predictable, homegrown sources. We should be putting solar on any building that can take it. That's how we cut costs, strengthen energy security and give people real control over the energy they rely on every day."The market is poised for further growth with plug-in solar kits expected to become available from high street retailers and supermarkets in the coming months. The government recently announced that most new homes will likely have solar panels from 2028 and will lift a ban on sales of these kits.Andrew Dickinson, head of infrastructure at Heligan Group, explained: "Given the recent geopolitical events, the UK's reliance on global energy markets has become front and centre. The solution lies in a series of short-term initiatives to address the immediate impact of rising energy prices on homeowners. Plug-in solar is one of these solutions that is expected to lower the barriers to entry for homeowners. The previously lengthy process of roof assessment, design and installation by a specialist technician will no longer be necessary."A recent report from Electrify Britain, backed by Octopus, found that solar panels and heat pumps would significantly reduce vulnerability to fossil fuel price fluctuations. The report "Plug In, Pay Less" revealed that houses using these technologies would be almost immune to fossil fuel price rises: a 30% increase in wholesale gas and oil prices would translate into only a 1.7% rise in energy bills by 2035 for households using no gas or oil appliances.Energy bills are expected to rise by more than £300 this July, according to Cornwall Insight, a consultancy. Jess Ralston, head of energy at the Energy and Climate Intelligence Unit, commented: "Predictions of energy bills rising by hundreds of pounds will feel like deja vu to hard-working families as yet another gas price crisis pushes up the cost of living. Many are still saddled with debt from the last gas crisis while Putin and the oil and gas companies stand to benefit."Ralston added: "These wars and the global gas market are clearly beyond the UK's control, so the only way we have to permanently stabilise bills is to cut our use of gas and that means switching to electric heat pumps and renewables that squeeze gas power plants off the grid."Octopus Energy also noted a one-third increase in inquiries about leasing electric vehicles, further indicating a broader shift toward renewable energy solutions among British consumers.

US President Donald Trump has asserted that negotiations to end the war on Iran are ongoing, claiming Tehran is eager to make a deal. Speaking at the White House, Trump stated the US is talking to 'the right people' about a potential agreement, mentioning a 'very big present' related to 'oil and gas' allegedly gifted by Tehran. Trump's claims come as fighting continues, with Iran launching attacks on Israel and a strike near Iran's Bushehr nuclear plant. Iran's parliament speaker, Mohammad Baqer Ghalibaf, had previously dismissed Trump's claims as 'fake news.' Media reports suggest Washington has sent Iran a 15-point plan to end the war, which includes ending Iran's nuclear program and reopening the Strait of Hormuz. A Reuters/Ipsos poll found 61% of Americans disapprove of the attacks on Iran, while 35% approve. Iran's Ministry of Foreign Affairs acknowledged receiving messages from 'friendly countries' indicating a US request for negotiations. Negar Mortazavi, a senior non-resident fellow at the Center for International Policy, stated Iran would seek to end the war on its 'own terms,' including establishing deterrence and economic gains. Despite Trump's diplomatic efforts, Israeli military spokesman Effie Defrin said Israel's war plan remains 'unchanged,' aiming to 'deepen the damage and remove existential threats.' The US is reportedly preparing to send thousands of soldiers to the Middle East, fueling fears of a longer conflict.

In a groundbreaking experiment conducted in Colorado's Rocky Mountain meadows, scientists heated a patch of land by 2C for 29 years. The results are alarming: the area transformed from a lush, diverse grassland into a desert-like scrubland dominated by sagebrush. This 'shrubification' process, driven by rising temperatures, threatens the very existence of alpine grasslands worldwide.The experiment, conducted at the Rocky Mountain Biological Laboratory, involved warming five plots of 30 sq meters each by 2C using electric infrared radiators. The results showed a 150% increase in shrubs in warmed plots compared to those without heating. The surface soil dried by up to 20%, and shallow-rooted plants became stressed, leading to the extinction of some wildflowers.The implications extend far beyond Colorado. Alpine grasslands, which host 50% of European flora on just 3% of land, are particularly vulnerable. As temperatures rise, these ecosystems are likely to be irrevocably changed, leading to a loss of biodiversity. The phenomenon of 'shrubification' is not limited to mountain environments; it's also observed in Arctic landscapes, where shrub cover expanded by 2.2% each decade between 1984 and 2020.Conservation ecologists warn that while shrubs and trees bring benefits like shelter and carbon sequestration, their rapid expansion in cold environments is a symptom of climate change. The speed and scale of these changes are concerning, with potential knock-on impacts on the carbon cycle and ecosystem balance.As Lara Souza, lead researcher, notes, 'It's like flowers on steroids.' However, this vision of abundance is tinged with sadness at the prospect of irreversible changes to fragile landscapes. The future of these ecosystems, and many others like them, hangs in the balance as global temperatures continue to rise.

The Gran Chaco forest in Argentina, spanning across parts of Argentina, Bolivia, Paraguay, and Brazil, is facing a critical threat from deforestation. Small farmers, enticed by the promise of quick money from selling timber, often contribute to this environmental degradation. However, a collaborative effort between conservationists, NGOs, and international organizations is underway to support small-scale landowners and Indigenous communities in establishing alternative income sources. This initiative aims to enable them to resist the pressures of agribusiness and the timber market. Jorge Luna, a 55-year-old farmer, has taken a significant step towards preserving his 40-hectare land in Chaco province. He rejected an offer to cut down the trees and instead embarked on a second career as a forest tourist guide with Fundación Rewilding Argentina, a non-profit organization working to restore parts of the Gran Chaco forest. Luna now rents out a small campsite to visitors and takes tourists on kayak tours along the Bermejito River. "At first, you didn’t give the plants value. It was a lack of knowledge of what they meant. Now, every leaf that sprouts has an added value," he says. Created in 2010 by Tompkins Conservation, Rewilding aims to protect vast tracts of territory and create economic opportunities for local communities while preserving the biosphere. The organization worked with 15 other organizations to convince the government of Chaco province to turn 128,000 hectares into the El Impenetrable national park, officially designated in 2014. Since then, Rewilding has established a network to support a budding tourism industry. It offers riverside glamping stays while promoting local and ancestral knowledge as possible sources of income. Women have returned to weaving and artisanal production, as well as providing home-cooked meals for visitors. According to Greenpeace, Argentina lost nearly 7 million hectares of native forest between 1998 and 2024, with most of it in the Gran Chaco. An estimated almost 120,000 hectares of forest were lost in northern Argentina in 2024, a 10% increase from the previous year. The primary causes of forest loss are the expansion of agriculture, mainly for intensive cattle ranching and genetically modified soya, and forest fires. The Gran Chaco forest also feeds the timber industry, particularly with the quebracho tree, which produces a tannin used in leather products, and carob trees. Environmental lawyers warn that the Gran Chaco could disappear within two decades if deforestation continues at its current pace. "The Chaco does not receive the same attention as the Amazon – few people even know it exists," says Enrique Viale, an Argentine environmental lawyer and activist. For conservation efforts to succeed, projects must be co-designed with the community, ensuring their long-term objectives are considered. Community empowerment, equal distribution of benefits, and capacity building are crucial factors. Mabel Figueroa, a local weaver, has resumed her craft since the national park opened, selling scarves, blankets, and ponchos to tourists. She raises sheep and dyes their wool with tree bark and forest plants, reviving an ancestral tradition.

The relationship between dogs and humans has long been a subject of fascination, and recent groundbreaking research has shed new light on the origins of this enduring bond. Published in the journal Nature, the study reveals that the genetic evidence for domestic dogs dates back an astonishing 15,000 years, a full 5,000 years earlier than previously thought.Ancient DNA analysis of dog remains has provided unprecedented insight into the early days of dog domestication. The oldest specimen, a 15,800-year-old dog buried alongside human remains in Anatolia, Turkey, and a 14,300-year-old jawbone from Gough's Cave in Somerset, England, are key findings that have helped researchers reevaluate the timeline of dog domestication.According to Dr. Lachie Scarsbrook of Ludwig Maximilian University of Munich, the study suggests that dogs with diverse ancestries already existed across Eurasia 15,000 years ago, from Somerset to Siberia. This raises the possibility that domestication occurred during the last ice age, more than 10,000 years before the emergence of other domestic plants and animals.The research, conducted by international teams, analyzed DNA from bones at various sites, including Gough's Cave, Pınarbaşı in Turkey, and two sites in Serbia. Advanced sequencing techniques allowed researchers to piece together tiny fragments of ancient DNA, enabling clear species identification for the first time.Key findings include:Dogs were widespread across Europe and western Asia by at least 14,000 years ago.Isotopic analysis revealed dogs consumed a diet rich in fish, matching the local human diet in Turkey.Evidence of deep emotional bonds between humans and dogs, including the burial of puppies over human remains.The study's authors suggest that dogs may have increased hunting efficiency or served as an early warning system against predators. The genetic relationship between dogs across sites implies that they may have spread rapidly across Europe, possibly through trade between unrelated groups.As Prof. Laurent Frantz notes, the fact that people exchanged dogs so early suggests these animals must have been important, serving purposes beyond being pets. The research provides a fascinating glimpse into the ancient partnership between humans and dogs, highlighting the significance of this bond in human history.
