Scientists issue warning over bizarre phenomenon spotted in Alaskan rivers: 'Have to be stained a lot...'
Scientists have issued a warning about a striking but alarming sight that's occurring in Alaskan rivers.
Green Matters detailed that at least 75 rivers in the state have started turning orange, a phenomenon that is even visible from space. Canadian photographer Taylor Roades has been documenting the startling scenes and recently posted he will be exhibiting his work under the title "Alaska's Rust Rivers" at the Anchorage Museum in March.
Brett Poulin — an environmental toxicologist at the University of California, Davis, and co-author of a study on the problem published in the Communications Earth & Environment journal — noted that the rivers "have to be stained a lot" to be seen at such a distance.
Researchers said this was happening because of toxic metals entering rivers from melting permafrost — defined as ground that has been frozen for more than two years.
Levels of zinc, nickel, copper, iron, and cadmium in rivers are increasing, with these metals once trapped in soil but now entering waterways because of rising global temperatures leading to increased ice melt.
The U.S. Geological Survey, cited by Green Matters, pointed out that the mildly acidic water pH level caused by these metals is equivalent to lemon juice or vinegar.
Scientists are concerned that acidic water levels, and the toxicity of the metals, could negatively impact both marine and land ecosystems. Notably, it's suggested that the degradation of water quality could harm spawning fish, which could later strike a blow to the U.S. fishing industry.
On top of that, it's feared that if we don't make changes to slow the rate of rising temperatures — which is exacerbated by the production of human-caused pollution — more permafrost could melt in the coming years, releasing further toxic materials into water sources.
Rising sea levels and increased soil erosion are additional worries following melting permafrost.

It sounds like a colossal task, but we can all take steps to prevent permafrost melt by reducing our production of planet-warming pollution, which traps heat in the atmosphere and encourages thermometers to rise.
Starting small, you could switch off electric devices at night to stop needless power usage. The electricity grid, while increasingly supported by wind and solar energy, still relies on burning dirty fuels to create energy.
Stepping up slightly, you and your family could switch to one plant-based meal a week. According to Earth Day, doing so could prevent the equivalent pollution of taking your car off the road for over a month.
Major actions include ditching your gas-guzzling car for an electric version or investing in sustainable domestic energy technology, like solar panels. Both of these changes could save you money in the long run, too.

Disposable vapes more toxic and carcinogenic than cigarettes, study shows
Illegal disposable e-cigarettes, also known as vapes, may present a greater danger than traditional cigarettes, according to a study from the University of California (UC) Davis. The research, published in the journal ACS Central Science, found that hazardous levels of several toxic heavy metals in illegal vapes could present a high cancer risk. Researchers used a special instrument to test the puffs from three popular vape brands — ELF Bar, Flum Pebble and Esco — that are not FDA-authorized for use in the U.S., but are widely sold by retailers. Rare Cancer Diagnoses Surge Dramatically Among Millennials And Gen X Three heavy metals — lead, nickel and antimony — were detected in all heavily flavored and lightly flavored devices that were tested. These metals are classified as carcinogens, potentially leading to various types of cancers, such as skin, lung and kidney, according to the National Institutes of Health (NIH). Read On The Fox News App All vapors exceeded the cancer risk limits for nickel, which has been linked to cardiovascular disease, asthma, lung fibrosis and respiratory tract cancer, per NIH. Brett Poulin, senior study author and assistant professor at the UC Davis Department of Environmental Toxicology, told Fox News Digital that he was shocked at the levels of toxic metals. "When I analyzed the first samples, the lead concentrations were so high that I genuinely thought the instrument was broken," he said. "The levels far exceeded anything in our past data, or even the published literature." Your Favorite Alcoholic Beverage Could Be Linked To Deadly Form Of Cancer, Study Finds One of the brands tested exposes users to as much lead as smoking 19 packs of cigarettes, the researchers discovered. Additionally, most of the disposable e-cigarettes tested in the study were found to contain greater levels of metals and metalloids than older refillable vapes. At one point, Poulin said, he physically opened a device and discovered that it was using leaded copper alloys, which are metals made primarily of copper with small amounts of lead. "These materials leached dangerous levels of lead into the e-liquid, even without the device being used," Poulin told Fox News Digital. "It remains unclear whether this was an intentional design choice, a cost-cutting measure or a manufacturing oversight." There is no known safe level of lead exposure, according to Poulin. "This neurotoxin poses serious health risks, particularly to children and adolescents, who are especially vulnerable." Daniel Sterman, M.D., director of the Pulmonary Oncology Program at the NYU Langone Perlmutter Cancer Center, told Fox News Digital that the study "clearly" demonstrates high concentrations of metal. "There are several health risks of vaping that we enumerate for our patients and their family members, [such as] risks of various lung diseases, including asthma, COPD and lung cancer," said Sterman, who was not involved in the study. The doctor noted that while it is challenging to establish a direct link of causation between disposable vapes and cancer, he does see cancer patients who use the devices. "Disposable vapes should be highly regulated by local, state and federal agencies, and restricted to those individuals 21 years or older," Sterman recommends. The doctor also called for the packaging on disposable vapes to clearly outline the many health risks, "particularly to teenagers and young adults." One of the primary limitations of the study was that only three disposable e-cigarette brands were tested out of the hundreds currently on the market. There are distinct differences in the metal leaching and profiles across all three brands, Poulin shared. "We still know very little about the metal content in the vast majority of untested disposable e-cigarette products," he said. "This gap in knowledge poses a significant public health concern, especially given the popularity of these devices." A spokesperson for the China-based brand, ELFBAR, told Fox News Digital that they refute the results of the study, claiming that they stopped shipments in May 2023. Click Here To Sign Up For Our Health Newsletter Due to ongoing trademark litigation, they are unable to market or sell products in the U.S., the company stated. "This market void has led to a surge in counterfeits, imitations and illicit variations misusing our brand name," the spokesperson said. "As such, we have every reason to believe the devices tested in this study are not genuine and were not manufactured by ELFBAR." The spokesperson acknowledged that smoking remains the leading cause of preventable death and disease worldwide, noting that the recent study "continues to undermine public understanding of smoking cessation." The other two brands tested in the study did not respond to requests for comment. Electronic cigarette use among adults increased from 4.5% in 2019 to 6.5% in 2023, according to the U.S. Centers for Disease Control and Prevention (CDC). Men are more likely to vape than women, while 15.5% of young adults between the ages of 21 and 24 reported using e-cigarettes, the above source states.

Nanostics to integrate prostate cancer test into standard of care
Nanostics has secured funding from Genome Canada and Genome Alberta to expedite the ClarityDX Prostate test integration into the standard of care for prostate cancer screening throughout the country. The funding, secured through the Canadian Biotechnology Innovation and Commercialization Initiative (CBIC), is set to accelerate the adoption of the test, starting in Alberta and eventually nationwide. This initiative is driven by partnerships in academia, clinical practice, and economics, under the guidance of the University of Alberta Translational Oncology Bird Dogs Chair Dr John Lewis, as well as collaborations with Partnerships and Innovation at Acute Care Alberta and Nanostics. The laboratory-developed test employs machine learning to assess the risk of aggressive prostate cancer. It combines blood-based biomarkers and clinical data to predict the likelihood of significant prostate cancer and is available as a patient-pay test at present. The project's main goal is to compile a comprehensive evidence package to show the clinical efficacy and economic benefits of the test. This is crucial for the reimbursement and public accessibility and will include outcomes from various studies, including health impact feasibility, clinical utility, and health system integration. Dr Lewis said: 'We are very grateful for Genome Canada's support of this project. 'This unique opportunity to collaborate directly with Acute Care Alberta will accelerate adoption of ClarityDX Prostate, and more importantly, help improve the outcomes of men in their journey of screening and diagnosis for prostate cancer.' ClarityDX Prostate aids male subjects and their healthcare providers to make informed decisions regarding the need for a biopsy after a high prostate-specific antigen (PSA) test or an abnormal digital rectal exam (DRE). Its availability spans several Canadian provinces, including Alberta, Quebec, Ontario, British Columbia, and Saskatchewan. Last year, the company collaborated with OncoHelix to extend the reach of ClarityDX Prostate to the Middle East, providing the blood test to healthcare providers and patients in the region. "Nanostics to integrate prostate cancer test into standard of care" was originally created and published by Medical Device Network, a GlobalData owned brand.
