Papaya extract thwarts growth of cancer cells in lab tests
05:01 10-03-2010; source: www.sciencedaily.com
Papaya extract seems to have a toxic effect on cancer cells in culture, suggesting a potential treatment. Scientists documented for the first time that papaya leaf extract boosts the production of key signaling molecules called Th1-type cytokines. This regulation of the immune system, in addition to papaya's direct anti-tumor effect on various cancers, suggests possible therapeutic strategies that use the immune system to fight cancers.
Sonic hedgehog gene found in an unexpected place during limb development

Sonic hedgehog is at work in mice limb buds in what is known as the ectoderm, the cell layer that gives rise to skin, researchers discovered. Finding Sonic hedgehog here is akin to discovering that yeast has crept from the batter to the frosting, where it has the surprising effect of limiting how much the cake rises. In this case, instead of causing appendages to grow in mice, Sonic hedgehog prevents digits from developing.
Behavioral problems in childhood doubles the risk of chronic widespread pain in adult life

Bad behavior in childhood is associated with long-term, chronic widespread pain in adult life, according to the findings of a study following nearly 20,000 people from birth in 1958 to the present day. The research found that children with severe behavior disturbances had approximately double the risk of chronic widespread pain by the time they reached the age of 45 than children who did not have behavior problems.
Designer nano luggage to carry drugs to diseased cells

Scientists have succeeded in growing empty particles derived from a plant virus and have made them carry useful chemicals. The external surface of these nano containers could be decorated with molecules that guide them to where they are needed in the body, before the chemical load is discharged to exert its effect on diseased cells. The containers are particles of the Cowpea mosaic virus, which is ideally suited for designing biomaterial at the nanoscale.
Hidden habits and movements of insect pests revealed by DNA barcoding

Researchers have found a faster way to study the spread and diet of insect pests. Using a technique called DNA barcoding, which involves the identification of species from a short DNA sequence, they studied populations of numerous moth and butterfly species across Papua New Guinea. DNA barcodes showed that migratory patterns and caterpillar diets are very dynamic.
