Male seahorses not only become pregnant and give birth, but do so in ways that take different forms, which make them unique research subjects to understand the evolution of pregnancy, according to Dr Olivia Roth from the Helmholtz Centre for Ocean Research Kiel (GEOMAR) in Germany.
Fragrant aromas from plants can actually be a response to attacks by insects, and can alert neighbours to an attack or summon the insects’ predators. Now, scientists are deciphering these secret codes to develop better, greener chemicals to defend crops against herbivorous insects.
A fine layer of dust thought to have been left by the first winter monsoon ever to cross northeastern Tibet has been uncovered by scientists, revealing the moment when the great weather phenomenon that waters much of Asia’s summers and dries its winters may have begun.
At 23.03 (local time) on Sunday 9 February, Europe’s newest mission to study the sun is set to lift off from Cape Canaveral in Florida, US. Called Solar Orbiter, this European Space Agency (ESA) mission will travel to within the orbit of planet Mercury to study the sun like never before, returning stunning new images of its surface.
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.
Demonstrating safety and changes to city regulations are needed to integrate autonomous shuttles with current systems, say researchers.
Dr Olivia Roth talks about her research on the evolution of male pregnancy.
Prof. J Murray Roberts is carrying out a health check on the Atlantic.
