Urine testing of people with HIV for tuberculosis can save lives and be cost-effective

Screening all hospitalized patients with HIV for tuberculosis (TB) using urine tests would improve life expectancy and be cost-effective in Malawi and South Africa. These findings from an international team of investigators have been published in The Lancet Global Health and could influence international guidelines on TB testing. “Urine testing for TB saves lives and […]

Genetic study provides novel insights into the evolution of skin color

Variation of light skin among Eurasian people evolved independently from different genetic backgrounds. Skin colour is one of the most visible and variable traits among humans and scientists have always been curious about how this variation evolved. Now, a study of diverse Latin American populations led by UCL geneticists has identified new genetic variations associated […]

Longer siesta on bright days

Light affects the clock neurons in the fly brain in three ways: The first light input to the clock neurons is via the cryptochrome (CRY); this light input is responsible for the detection of low-intensity light (LI). The second light input works via the compound eyes and basically detects middle-intensity light (MI). The third light […]

Do bigger brains equal smarter dogs? New study offers answers

Bigger dogs, with larger brains, perform better on certain measures of intelligence than their smaller canine counterparts, according to a new study led by the University of Arizona. Larger-brained dogs outperform smaller dogs on measures of executive functions — a set of cognitive processes that are necessary for controlling and coordinating other cognitive abilities and […]
