Cornwall is famous for its stunning gardens and lush landscapes, but a heated debate has erupted over plans to tackle a less attractive type of vegetation: roadside weeds.Unified officials have announced plans to use the controversial herbicide glyphosate to clear sidewalks and curbsides, after its use has been largely phased out over the past decade amid concerns about potential harm to humans and the peninsula’s rich ecosystem.Thousands of people have signed a petition opposing the plans, and dozens of protesters gathered at Truro’s courthouse on Tuesday to demonstrate ahead of a meeting where the issue will be discussed.They argued that…

For Louisville High School math teacher Lindsey Thurman, air quality is not an abstract concept. Her body tenses and spasms as she fights the pollutants to breathe. Thurman lives with the rare. Pulmonary arterial hypertension (PAH)According to the National Organization for Rare Diseases, it is characterized by “abnormally high” blood pressure in the pulmonary arteries. Lindsay Thurman, a high school math teacher, has pulmonary arterial hypertension (PAH), a rare condition that causes difficulty breathing. In 2021, she became the first person with PAH to complete a marathon. (Photo provided) “It appears that the lungs were built incorrectly, causing the blood…

For more than 150 years, guiding ideas in geometry have shaped the way mathematicians think about surfaces. Developed by the French mathematician Pierre Ossien Bonnet, this principle states that if you know two important properties of a densely curved surface at every point: its distance and its average curvature, you can determine its exact shape. New results from mathematicians at the Technical University of Munich (TUM), the Technical University of Berlin, and North Carolina State University show that this assumption does not always hold true. To challenge long-held beliefs, researchers constructed two compact, self-contained surfaces shaped like donuts known as…

An ambitious proposal to build a waste-to-energy facility in Fiji that could take in hundreds of thousands of tonnes of trash from Australia and other Pacific countries has sparked a public backlash and claims of “waste colonialism”.The proposed $900 million incinerator is being touted by Australian billionaire Ian Malouf, and the facility could reportedly supply up to 45 per cent of Fiji’s electricity grid needs, helping end its dependence on fossil fuel imports.Vuda Point’s incinerator can generate up to 80 megawatts of electricity per year, depending on the amount of trash being burned, and will be powered by a deep-water…

Vani Hari has 2.3 million followers on Instagram and just as many ideas for healthy food swaps. Hari, an entrepreneur and influential food activist with the “Make America Healthy Again” movement, regularly speaks out about snack alternatives containing corn syrup, seed oils and other ingredients on the blacklist of health-conscious Americans.For Valentine’s Day, YumEarth’s chocolate yams will replace artificially dyed M&Ms. (“Let me tell you these treats are better, but they’re still candy,” Hari writes.) For a Super Bowl party, avocado oil potato chips from Jackson’s instead of Lay’s. Looking for a less processed alternative to Chick-fil-A’s frosted lemonade? Why…

This article is published through the Indigenous News Alliance. On the second day of the United Nations Permanent Forum on Indigenous Peoples (UNPFII), experts called attention to the deep links between the health of indigenous peoples and nature, highlighting how environmental degradation, mining activities and climate change exacerbate health inequalities. The forum’s focus on Indigenous health follows new research by Jeffrey Ross, a descendant of the Standing Rock Sioux and former Permanent Forum member, which argues that the United Nations agency’s fragmented approach – addressing health, environment and land rights through separate mandates – has “consistently failed Indigenous peoples”. The…

Scientists have introduced a new method to track ocean surface currents over vast areas in much more detail than before. The technology, known as GOFLOW (Geostationary Ocean Flow), uses deep learning to analyze thermal images captured by weather satellites already in orbit. Because this method relies on existing satellites, it represents a major advance in ocean monitoring without the need for new equipment in space. The study was led by Luc Lenain of the Scripps Institution of Oceanography at the University of California, San Diego, and Kaushik Srinivasan, a Scripps alumnus now at the University of California, Los Angeles. Their…

A research team led by the Hong Kong University of Science and Technology (HKUST) has developed a pioneering artificial intelligence (AI) pathology analysis system that can accurately recognize multiple types of cancer without requiring additional training and using minimal samples. This breakthrough greatly increases the flexibility and efficiency of AI-assisted medicine and represents a major step toward widespread adoption of intelligent pathology. Approximately 20 million new cancer cases are diagnosed worldwide each year, and pathological examinations play a vital role in clinical diagnosis and treatment decision-making. However, with a severe global shortage of pathologists, the medical community increasingly needs innovative…

A new generation of artificial intelligence (AI) tools has the potential to save more patients in need of heart transplants by making better use of donor hearts that are currently discarded, according to research presented today by Brian Weida, MD, at the 46th Annual Meeting and Scientific Sessions of the International Society for Heart and Lung Transplantation (ISHLT). “There is a significant shortage of heart donors in the United States, and patients are waiting months or more for transplants, often requiring life support in the ICU, so the risks are very high,” said Dr. Weida, an assistant professor at New…

Identifying new species is not always easy. Scientists typically rely on physical characteristics that distinguish one species from another, but in nature, those differences do not always fall into appropriate categories. In some cases, two different species can look nearly identical. These are called cryptic species. In some cases, a single species can vary so much in appearance that it appears to be several different species. The challenge is even greater when both patterns emerge at the same time. Herpetologist Dr Chan Kin Ong, formerly with the Lee Kong Chian Museum of Natural History in Singapore and now with the…
