The European Space Agency’s giant 35m ground stations require regular maintenance and periodic mid-life upgrades to keep them working in tip-top condition, communicating with the Agency’s growing fleet of spacecraft millions of kilometres from home.

An international group of anthropologists offers a new theory about the diffusion of maize to the Southwestern United States and the impact it had. The study suggests that maize was passed from group to group of Southwestern hunter-gatherers.
More than half of HIV patients experience memory problems and other cognitive impairments as they age, and doctors know little about the underlying causes. New research suggests HIV-related cognitive deficits share a common link with Alzheimer’s-related dementia: low levels of the protein amyloid beta in the spinal fluid.

Researchers have discovered how the parasite Trypanosoma cruzi, which causes Chagas’ disease, prolongs its survival in infected cells. A protein on the parasite activates the enzyme Akt, which blocks cell death signals, preventing cell destruction and parasite elimination. Chagas’ disease affects some 8 to 11 million people throughout Latin America and even the United States.

Regardless of an individual’s dietary and lifestyle risk factors, living in a poorer or more socioeconomically deprived neighborhood may increase a person’s risk for death, according to new evidence.
Scientists have ruled out the possibility that methane is delivered to Mars by meteorites, raising fresh hopes that the gas might be generated by life on the red planet, in new research.

Blood vessel blockage, a common condition in old age or diabetes, leads to low blood flow and results in low oxygen, which can kill cells and tissues. Such blockages can require amputation resulting in loss of limbs. Now, using mice as their model, researchers have developed therapies that increase blood flow, improve movement and decrease [...]

Researchers reversed the growth of lung tumors in mice using a naturally occurring tumor suppressor microRNA. The study reveals that a tiny bit of RNA may one day play a big role in cancer treatment, and provides hope for future patients battling one of the most prevalent and difficult to treat cancers.
