An interdisciplinary team of scientists has identified a new mobile DNA element in the Wolbachia parasite, which may contribute to improved control strategies for mosquito vectors of diseases such as Dengue and West Nile virus.
Researchers have a new explanation for why those endless days of childhood seemed to last so much longer than they do now -- physics. According to the theory, the apparent temporal discrepancy can be blamed on the ever-slowing speed at which images are obtained and processed by the human brain as the body ages.
Research highlights role of immunological imprinting -- or how the immune system fights the flu after previous exposure to the virus via infections or vaccinations -- in the elicitation of new antibodies.
An active substance that has been known for 30 years could unexpectedly turn into a ray of hope against eye tumors. This is shown by a new study. The plant leaves of which contain the tested substance is anything but rare: At Christmas time you can find it in every well-assorted garden center.
As an organism grows and responds to its environment, genes in its cells are constantly turning on and off, with different patterns of gene expression in different cells. But can changes in gene expression be passed on from parents to their children and subsequent generations? Researchers have now demonstrated that epigenetic information carried by parental sperm chromosomes can cause changes in gene expression and development in the offspring.
