Biopolymer-Coated Nanocatalyst Could Drive a Hydrogen Fuel-Based Future

A newly devised nanorod catalyst could help water splitting by sunlight become a viable and eco-friendly route to hydrogen fuel.
Humanity’s consumption of fossil fuels drives massive detrimental changes to the environment, releasing carbon dioxide and other greenhouse gases into the atmosphere that are fueling the climate change crisis. Thus, a long-term sustainable alternative fuel source that is environmentally friendly is desperately needed.
One possible alternative for fossil fuels that has been proposed by researchers for some time is hydrogen (H2). The Universe’s most abundant element, hydrogen, is a high-energy-density molecule, and when it is used as a fuel, it produces only water as a by-product making it a clean alternative to fossil fuels too.
Freshwater Fish are Facing a Catastrophic Decline

Biodiversity in freshwater ecosystems is under severe threat, with up to one-third of freshwater fish species facing extinction, suggests a WWF report.
A new report from the World Wide Fund (WWF)¹ is a wake-up call to governments worldwide, highlighting that human activities are severely impacting freshwater fish.
The WWF has collaborated with 16 other conservation agencies, including the London Zoological Society (ZSL), Global Wildlife Conservation, and The Nature Conservancy, to produce The World s Forgotten Fishes, a report which suggests that freshwater fish are under threat with up to a third of species facing extinction.
