This week, after five years of research, two newly discovered antiviral molecules have been shown to combat coronaviruses. Johan Neyts of the Rega Institute for Medical Research in Leuven outlines how he hopes the new molecule developed by his team might help us deal with emerging pandemics in the future.

But as the US halts all Covid related research, will drugs like these ever hit the shelves? Among the grants terminated this week by the National Institute for Health is a programme called AViDD, AntiViral Drug Discovery, supporting 9 independent consortia. Annette von Delft of Oxford University and Ed Griffen of the drugs discovery company MedChemica spoke to us about the overnight shut down of years of work and importance of antiviral development.

The longest ever carbon-based molecules have been discovered by the Mars Curiosity rover. Caroline Freissinet of the Laboratoire Atmosph猫res et Observations Spatiales talked us through the meticulous planning and geological chance that made this possible, and whether these long chain alkanes could be a clue to discovering life on mars.

Researchers at Vanderbilt University have been delving into the genetic evolution of horses to discover the mutation that鈥檚 behind their runaway metabolic success. Gianni Castiglione explains how a mutation that should have been catastrophic instead helped horses to evolve from the size of dogs to the giant athletic animals we know today.
