With no end in sight for the oil gushing from the explosion site at the Deepwater Horizon drilling rig, anxious US officials are looking to researchers who study the Gulf of Mexico and its idiosyncratic currents to help determine where all the oil is and where it might be heading.

As oil continues to gush into the Gulf of Mexico in the wake of the Deepwater Horizon rig explosion, the question remains: how big an environmental disaster is this?

With oil still gushing from an offshore well in the Gulf of Mexico, some scientists and environmentalists worry that US federal agencies have not done enough to gather precious data on the spill, now into its second month.

US agencies have moved too slowly in gathering key data on the oil spill in the Gulf of Mexico. (Editorial)

A comparison of a recently published evidence-based map of the distribution of the Plasmodium falciparum malaria parasite with data from 1900, before the introduction of major malaria control measures, suggests that concerns that rising temperatures are a threat to malaria control efforts are misplaced.

The upper ocean acts as a giant heat sink and has absorbed the majority of excess energy generated by anthropogenic greenhouse gasses. This makes ocean heat content, potentially, a key indicator of climate change. But to be useful for evaluating the global energy balance and as a constraint on climate models, the measurement uncertainties of such a key indicator need to be well understood.

Malaria caused by Plasmodium falciparum is a disease that is responsible for 880,000 deaths per year worldwide. Vaccine development has proved difficult and resistance has emerged for most antimalarial drugs. To discover new antimalarial chemotypes, we have used a phenotypic forward chemical genetic approach to assay 309,474 chemicals.

There are still nearly 250 million malaria cases reported annually, over 800,000 fatal, with most deaths being children under 5. The malaria parasite Plasmodium falciparum is notoriously adept at developing drug resistance, and new drugs are urgently needed. Two reports raise hopes that alternatives to artemisinins might be found, by identifying thousands of compounds inhibiting the growth of P.
