NASA study confirms biofuels reduce jet engine pollution

Some close-quarter flying in the wake of a jet has provided new insights on reducing aircraft pollution. We fly beyond Earth to hunt down exoplanets that had falsely been deemed too cold for life as our definition of the habitable zone changes.

Karen Schoonbee reports from Cape Town on the growing problem of women using crystal meth – known locally as tik – during their pregnancies.  We hear from a doctor about the developmental delays experienced by these “tik babies”.  

This week is the sixth anniversary of the start of the Syrian conflict.  To mark this, a new study has been published in the journal The Lancet, highlighting the impact of the war on health care in the country.  It concludes that healthcare in Syria is being used as a weapon of war on an unprecedented scale

A tracking technology previously used to locate New Zealand’s endangered kiwi bird is now being used to track people with dementia at risk of wandering off.  We also hear how bears and lemurs hibernate in the hope that one day human could slip into suspended animation.
