Hookworms employ live fast/die young strategy in fur seal pup hosts ScienceDaily: Latest Science News urn:uuid:e16cf930-32da-f86e-8571-2d12cbe761b5 Thu, 20 Sep 2018 10:55:40 -0500 Hookworms exploit a live fast/die young strategy in their South American fur seal pup hosts. As a result, they often kill their host, rather than finding a happy equilibrium. Scientists are concerned that this type of hookworm infection could eventually pose a risk to critically endangered populations of fur seals.

Anti-cancer drugs may hold key to overcoming antimalarial drug resistance ScienceDaily: Latest Science News urn:uuid:ad3a974a-7085-c73a-1200-04b3a0fd7c78 Thu, 20 Sep 2018 09:21:52 -0500 Scientists have found a way to boost the efficacy of the antimalarial drug artemesinin with the help of chemotherapy medicines. Artemisinin works through a 'double whammy' attack on the deadly parasite. The drug damages proteins in malaria parasites and clogs the parasite's waste disposal system, known as the proteasome, which chemo can target.

To understand how birds find and navigate these thermal plumes, researchers used reinforcement learning to train gliders to autonomously navigate atmospheric thermals. The research highlights the role of vertical wind accelerations and roll-wise torques as viable biological cues for soaring birds. The findings also provide a navigational strategy that directly applies to the development of UAVs.
