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.
The Atlantic Ocean is under threat from fishing, fossil fuel extraction and deep-sea mining, and the onus should be on these industries to prove that their exploitation is sustainable rather than requiring scientists to come up with reasons to protect it, says Professor J Murray Roberts, a marine biologist at the University of Edinburgh, UK.
How people and deliveries get to their final destination is currently making urban environments harder places to live, and cities need to solve this ‘last mile problem’ by using a combination of ‘carrot and stick’ measures, according to Karen Vancluysen, secretary general of Polis, a network of European cities and regions working on sustainable innovative transport solutions.
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.
We need an active public debate on the ethics of gene editing technology to realise its potential and prevent it being used in nefarious ways, for example by the military and amateur scientists, and to take cultural differences into account, according to Professor Christiane Woopen, executive director of the Centre for Ethics, Rights, Economics and Social Sciences of Health (CERES) at Germany’s University of Cologne.
Breeding together corals that have naturally high heat tolerance and planting them on coral reefs could increase the reefs’ resilience to climate change and reduce the impact of bleaching events, according to Dr James Guest, a coral reef ecologist from Newcastle University, UK. He is studying this ‘assisted evolution’ approach to coral conservation and examining the risks associated with it.
Drugs that activate or block the body’s oxygen-sensing machinery to treat conditions such as anaemia in patients with chronic kidney disease and cancer are being made possible because we now understand the way that cells respond to oxygen deprivation, according to Sir Peter Ratcliffe, one of three winners of this year’s Nobel prize in physiology or medicine.
From the first discoveries of planets beyond our solar system in the 1990s, we now know of thousands of alien worlds, some of which could even be habitable to life as we know it. Now we need to detect more of these exoplanets and study them in detail, says astronomer Dr Michaël Gillon from the University of Liège in Belgium, who was involved in one of the most important exoplanet discoveries to date.
The most powerful source of misperceptions about important issues such as immigration and climate change are false beliefs rooted in people’s political or social preferences, but having people who question authority is also important for a society, according to Professor Jason Reifler, a political scientist at the University of Exeter, UK.
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.
