Canadian cancer clinicians call for urgent, vital improvements to cancer care
New cancer clinician initiative calls attention to challenges faced daily by clinicians on behalf of their patients OTTAWA, ON and SASKATOON, SK, July 8, 2025 /CNW/ - A group of Canadian clinicians who care for and treat cancer patients has launched a new platform to give voice to their calls for urgent and vitally needed changes and improvements in cancer care across Canada. The Cancer Clinician Advocacy Forum (CCAF) is a newly established network of cancer care clinicians from across Canada – including pharmacists, nurses and physicians – who are committed to improving care for patients. Together, they aim to address public policy issues that impact the quality, accessibility and outcomes of cancer care. CCAF has now launched its own website to publicize its issues and positions at "We want to draw attention to the problems we as cancer care clinicians face on behalf of our patients every day across Canada in providing equitable and timely access to diagnosis, treatment and care for a disease that will affect nearly half of Canadians in their lifetime," said CCAF Co-Chair Dr. Sandeep Sehdev, a medical oncologist at the Ottawa Hospital Cancer Centre. "We also want to help our health systems develop and implement practical solutions to these issues," said Dr. Mita Manna, the other CCAF Co-Chair and a medical oncologist at the Saskatchewan Cancer Agency in Saskatoon. Members of CCAF are raising a united voice to seek urgent action on three key priorities for cancer care in Canada: Expanding access to diagnostic testing, including molecular genetic testing that more accurately defines each cancer, leading to more targeted and effective treatment Ensuring faster and more equitable access to cancer therapies to improve outcomes Improving efficiencies in patient care and addressing human resources constraints This urgent action is needed to overcome the challenges and barriers being faced by health professionals in providing optimal cancer care for their patients, including these four key issues: Lack of primary care: More than one in five Canadians do not have a primary care provider, resulting in delays that lead to cancer diagnoses at a later stage when it is harder to treat effectively. Delays in new medicines: Canada ranks last in the G7 and 19th out of 20 leading countries for the time it takes for patients to access newly approved medicines. Access issues for the best technology and therapy: Cancer clinicians face unacceptable delays and restrictions in accessing optimal technologies and therapies for patients. Physicians across specialties spend 8.5 million hours per year on unnecessary administrative tasks – time that could be spent instead on 55.6 million patient visits. Lack of preparedness for genomic medicine: There is high variability among provinces in providing timely access to the molecular testing that results in improved survivorship and health outcomes. About Cancer Clinician Advocacy Forum CCAF emerged out of a two-day forum in Toronto in September 2023, which resulted in a formal report published in Current Oncology in February 2024, co-authored by 19 experts from across Canada. This report highlights the frustration clinicians experience due to lengthy delays in the approval and funding of optimal technologies and therapies for their patients.

Bitcoin Mining Centralization in the U.S.: A New Risk for the Industry?
A groundbreaking study from the Cambridge Centre for Alternative Finance (CCAF) claims that the United States now dominates Bitcoin mining, controlling as much as 75.4% of the global hashing power. 'The U.S. has solidified its position as the largest global mining hub (75.4% of reported activity),' the CCAF reports, based on a survey of 49 mining firms representing nearly half the Bitcoin network's hashrate. This concentration, equating to roughly 600 exahashes per second (EH/s) of the global 796 EH/s, raises a pressing concern: Is Bitcoin mining becoming dangerously centralized in the U.S., and what risks does this pose for the emerging asset's future? Howard Lutnick, U.S. Secretary of Commerce and former CEO of Cantor Fitzgerald, recently shared insights into the Trump administration's vision to position the U.S. as a Bitcoin superpower. 'It's like gold. To me. It's a commodity,' Lutnick said in an interview with Frank Corva of Bitcoin Magazine, highlighting Bitcoin's fixed supply of 21 million coins. He outlined plans to 'turbocharge' U.S. mining through the Commerce Department's Investment Accelerator, which streamlines permits for miners to build off-grid power plants. 'You can build your own power plant next to [your data center]. I mean, think about that for a second,' he said. This pro-business stance has fueled America's mining boom, but the CCAF's findings suggest a downside: centralization. For years, Bitcoiners worried about China's dominance, which peaked at 65–75% of global hashrate before its June 2021 mining ban. 'In 2019, China dominated global Bitcoin mining, accounting for 65–75% of the total Bitcoin network,' a 2025 Nature Communications study notes. When China banned mining, hashrate dispersed globally, with many operations relocating to the U.S., drawn to states with abundant energy and favorable policies. This shift caused a 50% market correction but paved the way for a 130% rise toward the end of the year, demonstrating the market's resilience. Read More Bitcoin Covenants: CHECKTEMPLATEVERIFY (BIP 119) While China's historical hashrate concentration never led to network abuse, it was a constant concern. Now, with the U.S. holding 75% of hashrate, similar risks emerge. The Trump administration is Bitcoin-friendly, but a future administration could turn hostile, leveraging centralized hashrate to control the network. Unlike China's ban, a future U.S. government might try to regulate or manipulate mining, using executive powers like sanctions to censor transactions — a threat amplified by mining's concentration. The U.S.'s federal structure offers a potential safeguard. The division of powers between states and the federal government could enable resistance to federal overreach. In states with significant mining activity, officials and the public might argue that manipulating the industry harms Bitcoin's value, impacting investors. Such resistance could preserve the network's integrity. The weakening of the U.S. monetary sanctions regime might play to our advantage. Following the 2022 seizure of Russian treasuries, nations misaligned with U.S. policy have reduced U.S. bond purchases, undermining the fiat rails abused in sanctions. The Trump administration is shifting toward tariffs to control goods rather than money flows, potentially reducing the threat of monetary censorship. This pivot buys Bitcoin time, as centralized hashrate may be a soft target for federal intervention. Nevertheless, American Bitcoiners must stay proactive. Deepening Bitcoin adoption to embed it widely in the economy and throughout the world could deter censorship, as attacks on the network would harm personal wealth, spurring backlash. History also shows miners adapt when displaced — China's ban proved that — but governments learn. A future U.S. administration might not ban mining but seek to control it, exploiting centralization. The Bitcoin industry faces a critical juncture. With as much as 75.4% of hashrate in the U.S., even low estimates of 50% present a centralization risk that looms large. Should we diversify globally or lean into America's mining dominance? As Lutnick's vision unfolds, Bitcoiners must ensure this sovereign money remains resilient, regardless of who holds power.

Analyst uncovers unexpected source powering crypto industry: 'The future of bitcoin mining'
Bitcoin is often criticized for its high energy use, which contributes to planet-warming pollution. However, as The Crypto Times reported, one climate tech investor wants to get the word out that bitcoin derives the biggest share of its energy from a potentially unexpected source: hydroelectric power. Daniel Batten's findings show that the bitcoin network gets 23.12% of its energy from hydroelectric sources, with coal and gas sources following at 22.92% and 21.14%, respectively. This updates findings from the Cambridge Centre for Alternative Finance, which previously identified coal as bitcoin's largest energy source. However, the CCAF report confirmed that the estimate was limited, at least in part, by limited real-world data. According to The Crypto Times, Batten's difference comes from including off-grid mining operations using renewable energy. "The study by Daniel shows that the future of Bitcoin mining indeed belongs to hydro power," the Crypto Times said. While bitcoin operations don't directly produce pollution, their computing processes require massive amounts of electricity. That means when bitcoin data centers are connected to power grids relying mostly on dirty energy (such as coal, gas, and oil), it increases local air pollution, in addition to putting a strain on those grids. That problem is beginning to subside as more bitcoin mining operations strike deals to gain their own dedicated power sources — as Mara Holdings, whose advisory board includes Batten, recently did with a Texas wind farm — or to operate exclusively on excess energy from plants that have a habit of overproducing. Looking forward, it's crucial for the industry to continue to mitigate these environmental effects and get those coal and gas percentages down into the single digits. According to the North American Electric Reliability Corporation, reporting in late 2024, its estimates for electricity demand are rising faster than at any point in the last 20 years, and crypto and artificial intelligence data centers are complicating demand forecasts. Their ability to scale also strains energy grids and can make them less stable. Plus, higher demand generally means higher electricity bills for consumers. The good news is it benefits crypto miners to seek the lowest electricity prices, since their profit margins depend on it. Renewable energy is typically cheaper, and it's much cheaper once built, so increasing renewables is a win-win for crypto and the environment. Energy innovation is essential for this transition. For example, methane pollution from landfills — the third-largest source of human-related methane pollution in the U.S. — can be used for energy. So Vespene Energy developed technology that converts landfill gas on-site to power data processing centers, which offsets gas pollution and generates revenue at the same time. Inspiring such efforts is one example of how these energy-intensive industries can be part of the solution. Bitcoin mining can also support the transition to green energy with financial incentives, according to sources. A study in ACS Sustainable Chemistry & Engineering found that 32 planned renewable sites could generate $47 million in profit by supporting bitcoin mining before going commercial.

We've seen some crypto investors prioritizing clean energy for mining facilities. However, as the world's largest crypto asset, bitcoin must make more progress for the industry to become sustainable. "Bitcoin relies on miners using powerful computational power to solve complex puzzles, consuming massive amounts of energy. Crypto mining's future relies on embracing sustainable and ethical practices to ensure it's not just green but genuinely clean," Tin Pei Ling, co-president of digital asset platform MetaComp, told Financial News. "It is in the industry's interest to reduce energy usage and its environmental impact as it evolves," added David Lenigas, chair of Vinanz, a London Stock Exchange-listed bitcoin mining firm.
