Lake ice provides natural resources such as fresh water, food, transportation, and renewable energy. But it also supports emotional wellbeing by connecting remote communities through ice roads... click to read more
Gaseous heavy metals in the atmosphere of an ultra-hot exoplanet

Halfway between the coastal beaches of Southern California and the paradise islands of Hawaii lies the Great Pacific Garbage Patch (GPGP) - a patch of plastic debris covering a vast area of the oceanic surface. Despite the name, it is not a compact garbage island... click to read more
Environmental change and fruits, vegetables, nuts, and seeds: what is the gap to bridge?
There is now much scientific evidence to suggest that our planet's environment is changing rapidly and that this poses an ever-increasing risk to human health and our food systems. Changes such as agricultural land degradation, water shortages, rising temperatures and changing rainfall patterns can affect... click to read more
