Week 39 (24 - 30)

Viruses like these H1N1 influenza particles rely on host cells to reproduce, but they can still show social behavior, interacting with other viruses by competing, cooperating and sometimes cheating to succeed. This new behavioral approach to viruses could lead to new insights into how to control infectious diseases.

Week 38 (17 - 23)

A malaria parasite (yellow) invading liver cells (pink/red).Researchers from the Walter and Eliza Hall Institute in Melbourne, Australia, have shown for the first time that carbohydrates on the surface of malaria parasites play a critical role in malaria's ability to infect mosquito and human hosts. The discovery also suggests steps that may improve the only malaria vaccine approved to protect people against Plasmodium falciparum malaria the most deadly form of the disease.

Week 37 (10 - 16)

Two new Princeton-led studies provide a detailed look at an essential part of algae's growth machinery, with the eventual goal of applying this knowledge to improving the growth of crops. In this image, the researchers used a technique called cryo-electron tomography to image an algal structure called the pyrenoid, which concentrates carbon dioxide to make it more readily available for photosynthetic enzymes (purple). The yellow tubules inside the green tubes are thought to bring carbon and other materials into the pyrenoid.

Week 35 (27 - 02)

A laser arouses fluorescence from engineered light-emitting E. coli bacteria suspended within a microfluidic chip device. The bacteria flicker as they move, and their fluorescent signal propagates throughout the device.
