Each year, more than a million wildebeest migrate across the grassy plains of the Serengeti National Park in Tanzania into Kenya’s Masai Mara National Reserve. But on the borders of these protected areas, human populations are increasing and wild ecosystems are struggling to survive in the face of development. Understanding these pressures is crucial for protecting people and wildlife, and to curb illegal activities such as poaching.
Genghis Khan’s conquering armies fed on dried curd as they crossed the vast steppes of Eurasia, ancient Romans imported pungent cheeses from France, and Bedouin tribes crossing the Arabian Desert have for centuries survived on camel’s milk.
Applying a coat of paint on the walls of a house may soon help to heat it, saving energy and reducing CO2 emissions. It could also clean the air that we breathe, breaking down chemicals and pollutants, and eliminating harmful pathogens.
Facing the death of a loved one, being given a life-threatening diagnosis, or living through a natural disaster is difficult enough. But those who get through these traumatic life events often face further ill effects.
Scientists may have solved a 25-year-old puzzle about the mysterious behaviour of certain glaciers in High Mountain Asia. In most of this region, they are shrinking; but in the northwest, they are growing.
Trees and insects may play a significant role in the emission of methane – a potent greenhouse gas – and improving our understanding of exactly how this happens could help in targeting more effective ways to fight global warming.
We need to understand how glaciers are shrinking in order to better adapt to climate change impacts such as changes to water supply, landslides and avalanches, says Professor Andreas Kääb, a glacier expert from the University of Oslo in Norway.
Declaring a global planetary emergency, improving sub-volcanic imaging to predict eruptions and developing artificial intelligence that works for humans are some of the urgent actions and research that experts in different fields want to see in 2020.
Metagenomics can help us spot emerging diseases, says virologist Marion Koopmans.
What are they and why are they promising for coronavirus?
The more satellite launches we do, the bigger the risk of damage or debris, says Dimitra Stefoudi.
