The University of Texas Medical Branch at Galveston's Scott Weaver, globally recognized for his expertise in mosquito-borne diseases, has been studying chikungunya for more than 15 years.
The mosquito-borne chikungunya virus has been the subject of increasing attention as it spreads throughout South America, Central America, the Caribbean and Mexico. This painful and potentially debilitating disease is predicted to soon spread to the U.S.

This photo shows HIV, the AIDS virus (yellow), infecting a human immune cell.
The AIDS virus can genetically evolve and independently replicate in patients' brains early in the illness process, researchers funded by the National Institutes of Health have discovered. An analysis of cerebral spinal fluid (CSF), a window into brain chemical activity, revealed that for a subset of patients HIV had started replicating within the brain within the first four months of infection. CSF in 30 percent of HIV-infected patients tracked showed at least transient signs of inflammation - suggesting an active infectious process - or viral replication within the first two years of infection. There was also evidence that the mutating virus can evolve a genome in the central nervous system that is distinct from that in the periphery.

New research shows bacteria can use tiny magnetic particles to effectively create a 'natural battery.' According to work published in journal Science on 27 March, the bacteria can load electrons onto and discharge electrons from microscopic particles of magnetite. This discovery holds out the potential of using this mechanism to help clean up environmental pollution, and other bioengineering applications. The European Association of Geochemistry is highlighting this work as especially interesting.

Researchers at the University of California, San Diego School of Medicine have discovered a control switch for the unfolded protein response (UPR), a cellular stress relief mechanism drawing major scientific interest because of its role in cancer, diabetes, inflammatory disorders and several neural degenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS), otherwise known as Lou Gehrig's disease.

Bacteria that cause many hospital-associated infections are ready to quickly share genes that allow them to resist powerful antibiotics. The illustration, based on electron micrographs and created by the Centers...
Antibiotic resistance is poised to spread globally among bacteria frequently implicated in respiratory and urinary infections in hospital settings, according to new research at Washington University School of Medicine in St. Louis.

This is a ring-tailed lemur (Lemur catta) indigenous only to Madagascar. UC's Brooke Crowley is researching lemurs' geographic mobility.
Out of the mouths of lemurs come many answers to old mysteries about Madagascar's unique fauna. What were their origins, and how and why did they move around?

Scientists, led by the University of Michigan Medical School, coax stem cells to form mini lungs, 3-D structures that mimic human lungs and survived in the lab for 100 days.
Scientists have coaxed stem cells to grow the first three-dimensional mini lungs.

Figure 1 shows hydrogel-aptamer capture and release. The hydrogel can be made sensitive to environmental variables. In the current study, changes in solution pH cause the hydrogel to either swell... Like vast international trading companies, biological systems pick up freight items (in the form of small molecules), transport them from place to place and release them at their proper destination. These ubiquitous processes are critical for activities ranging from photosynthesis to neuronal signaling.

This is an abstract representation of virus inducing enzyme to produce lipid envelope.
More than 60 percent of the world's population is infected with a type of herpes virus called human cytomegalovirus. The virus replicates by commandeering the host cell's metabolism but the details of this maneuver are unclear.
