 E-Mail PITTSBURGH--Babies whose births were depicted in Bollywood films from the 1950s and 60s were more often than not boys; in today's films, boy and girl newborns are about evenly split. In the 50s and 60s, dowries were socially acceptable; today, not so much. And Bollywood's conception of beauty has remained consistent through the years: beautiful women have fair skin. Fans and critics of Bollywood -- the popular name for a $2.1 billion film industry centered in Mumbai, India -- might have some inkling of all this, particularly as movies often reflect changes in the culture. But these i...

 E-Mail A team of researchers concludes that a game-theory approach may offer new insights into both the spread and disruption of viruses, such as SARS-CoV-2. Its work, described in the journal Royal Society Interface, applies a "signaling game" to an analysis of cellular processes in illuminating molecular behavior. "We need new models and technologies at many levels in order to understand how to tame viral pandemics," explains Bud Mishra, a professor at NYU's Courant Institute of Mathematical Sciences and one of the paper's authors. "At the biomolecular level, we explain how cellularizati...

 E-Mail Torino, February 24, 2021 - The eukaryotic cell is the basic unit of animals and plants. At the microscope, it looks highly structured and subdivided in many membrane-bound compartments. Each compartment has a specific function, and its membrane is populated by specific molecules. How does the cell preserve this amazing internal order, and (in the absence of pathologies) does not degrade into a shapeless bunch of molecules? Such degradation is countered by a continuous process of molecule sorting by which similar molecules are collected and dispatched to the "right" destinations, si...

Scientists have made a pivotal breakthrough in the quest to understand how single-cell green algae are able to keep track of the light as they swim.

 E-Mail BROOKLYN, New York, Wednesday, February 24, 2021 - Travel bans have been key to efforts by many countries to control the spread of COVID-19. But new research aimed at providing a decision support system to Italian policy makers, recently published in the Journal of the Royal Society Interface, suggests that reducing individual activity (i.e., social distancing, closure of non-essential business, etc.) is far superior in controlling the dissemination of Sars-CoV-2, the virus that causes COVID-19. The research, which has implications for the United States and other countries, found th...
