A component of red wine and grapes can help control inflammation induced by a bacterial pathogen that is linked to upper respiratory tract inflammatory diseases such as asthma, chronic obstructive pulmonary diseases (COPD) and middle ear infection (otitis media), according to a study.
Eating bread made with ancient grains could help lower cholesterol and blood glucose, a recent randomized trial suggests. Compared with modern grain varieties which are often heavily refined, ancient grains offer antioxidant and anti-inflammatory profiles. They also contain beneficial vitamins (B and E), minerals (eg, magnesium, iron, potassium), which protect against chronic diseases.
A new study of lead pollution in the North Atlantic provides strong evidence that leaded petrol emissions have declined over the past few decades. For the first time in around 40 years, scientists have detected lead from natural sources in samples from this ocean. In the intervening period, the proportion of lead in the ocean from humanmade sources, most importantly leaded petrol emissions, had been so high that it was not possible to detect any lead from natural sources.
Solar panels are proliferating across the globe to help reduce the world's dependency on fossil fuels. But conventional panels are not without environmental costs, too. Now scientists report a new advance toward more practical, "greener" solar cells made with inexpensive halide perovskite materials. They have developed low-bandgap perovskite solar cells with a reduced lead content and a power conversion efficiency of 15 percent.
A fungus that compromises the immune system of mosquitoes, making them more susceptible to infection with the parasite that causes malaria, has been discovered by scientists. Because environmental microorganisms can vary greatly from region to region, the researchers say the findings may help explain variations in the prevalence of malaria in different geographic areas.
