New research is shedding light on food and beverage products linked to per- and polyfluoroalkyl substances, or PFAS, and suggesting potential solutions for protecting the public. PFAS are known to be harmful to health: They can disrupt hormones, weaken bones and increase disease risk. Sometimes called “forever chemicals” because they take so long to break down, PFAS are used in fabrics, furniture and other household items—but they are also hard to get rid of. Recent tests now trace the chemicals to livestock, drinking water and food packaging, but little is known about the extent of that contamination. A new study, funded in part ...

The production of aluminium generates around 180 million tonnes of toxic red mud every year. Scientists at the Max-Planck-Institut für Eisenforschung, a centre for iron research, have now shown how green steel can be produced from aluminium production waste in a relatively simple way. In an electric arc furnace similar to those used in the steel industry for decades, they convert the iron oxide contained in the red mud into iron using hydrogen plasma. With this process, almost 700 million tonnes of CO2-free steel could be produced from the four billion tonnes of red ...

Sleep apnea, which involves recurring, temporary interruptions of breathing during sleep, can disturb regulation of blood lipid levels, a key factor in the development of cardiovascular disease. A University of Ottawa research team has shown that the impact of sleep apnea on the metabolism of blood lipids differs by sex, with women regulating their blood lipids better than men. The study was conducted by Nicholas Goulet, Caroline Marcoux, Renée Morin, Jean-François Mauger and Vincent Bourgon, under the supervision of Pascal ...

Tiny plankton – measuring less than 20µm (or 0.02mm) in diameter – make up the majority of plankton in the ocean and play a critical role in the planet’s health, according to new research. However, scientists say challenges in identifying them have led to them becoming a silent majority that is currently being overlooked when it comes to global ocean policy. The study is one of the first to explore the abundance and importance of these tiny ocean inhabitants around the UK coastline, with the technology capable of monitoring them only having been introduced in around 2010. However, ...

Researchers have found that adolescents being bullied by their peers are at greater risk of the early stages of psychotic episodes and in turn experience lower levels of a key neurotransmitter in a part of the brain involved in regulating emotions. The finding suggests that this neurotransmitter — a chemical messenger that transmits nerve impulses for communication by a nerve cell — may be a potential target for pharmaceutical interventions aimed at reducing the risk of psychotic disorders. Psychosis is a mental state characterized by loss of contact with reality, incoherent speech and behavior, and typically hallucinations and delusions seen in psychiatric disorders ...

The prevalence of inflammatory bowel disease (IBD), encompassing ulcerative colitis (UC) and Crohn's disease (CD), is rapidly increasing worldwide, affecting an estimated 6.8 million people. This surge brings significant economic burdens, with annual healthcare costs exceeding $12,000 and $7,000 for CD and UC patients, respectively. Tailored drug selection based on individual factors can potentially reduce these costs and improve patient outcomes. Factors associated with a Western lifestyle such as urbanization, high animal protein intake, ultra-processed foods, and reduced fiber ...

Utilizing crude glycerol for the synthesis of high-value products offers a promising solution to counter the adverse effects of declining glycerol prices in the biodiesel sector. The prevalence of crude glycerol, a by-product of biodiesel production, across agriculture, biofuel, and industrial sectors is steadily rising.
