Chlorovirus ATCV-1, a Green Algae Virus, May Slow Human Brain Activity

By Roberta Attanasio Chlorella viruses, or chloroviruses, infect green algae, single-celled organisms present throughout the world in freshwater ecosystems such as lakes and ponds. Now, it seems that chlorovirues also infect humans, causing changes in cognitive functions — the processes by which information is perceived, registered, stored, retrieved, and used. In other words, chloroviruses influence the ability to acquire and...

Nanoparticles and Sunscreen Products: Toxicity to Sea Life in Coastal Waters

By Roberta Attanasio The debate on the safety of titanium dioxide (TiO2) and zinc oxide (ZnO) nanoparticles contained in sunscreen products is still on. Some scientists have raised concerns about the negative impact that these tiny particles — generally between one and 100 nanometers (between one and 100 billionths of a meter) across — may have on human health. Due to their small size, nanoparticles might do harm to humans...

Global Health Threats: Instant Noodles

By Roberta Attanasio Instant noodles: convenient, cheap, maybe tasty, and bad for your health. Invented by Momofuku Ando after World War II to provide food for the masses, they became popular around the world in a relatively short time. However, back in 1991, tests carried out by the Australian Consumers’ Association showed that a single serving of noodles contained the same amount of fat present in a cup of potato chips. What...

Global Threats: Soil and Topsoil Erosion and Degradation

By Roberta Attanasio “Soil anaemia also breeds human anaemia. Micronutrient deficiency in the soil results in micronutrient malnutrition in people, since crops grown on such soils tend to be deficient in the nutrients needed to fight hidden hunger. (…) Managing our soil and water resources in a sustainable and equitable manner needs a new political vision.” M.S. Swaminathan — the “Indian Father of Green...
