Mussel adhesive inspires tough coating for living cells

2011-04-07
(Press-News.org) Inspired by Mother Nature, scientists are reporting development of a protective coating with the potential to enable living cells to survive in a dormant condition for long periods despite intense heat, dryness and other hostile conditions. In a report in Journal of the American Chemical Society, they liken the coating to the armor that encloses the spores that protect anthrax and certain other bacterial cells, making those microbes difficult to kill.

Insung S. Choi and colleagues say their simple method for coating the yeast cells could "serve as a new strategy for controlling cell division and protection of artificial spore like structures in a designed way." The technique could be used to encapsulate individual cells for a variety of purposes, including the creation of tiny chemical probes, single-cell chemical factories, and perhaps armor for transplanted cells used in anti-cancer therapies.

The new coating is an organic material called polydopamine, chemically similar to mussel adhesive. In laboratory experiments, the coating slowed down cell division in the yeast, while protecting them from cell-digesting chemicals. "We believe that polydopamine encapsulation would be a good starting point for both fundamental research and applications based on artificial spores," Choi and colleagues note in their study, "as it endows living cells with durability against harsh environments, controllability in cell cycles, and reactivity for cell-surface modification."

Three new bright blue pigments with origins in the hometown of Shakespeare's star-crossed lovers Romeo and Juliet have become stars in a drama that is unsettling experts on conservation of archaeological treasures around the world. That's the topic of an article on the solution of an archaeological 'whodunit' involving those new-to-science pigments in the current edition of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. C&EN Associate Editor Carmen Drahl notes in the article that the drama began last year when prehistoric flint tools began showing visible ...

What the world needs now? More wisdom

2011-04-07
This release is available in French. Montreal, April 6, 2011 – Revolution in Libya. Revolution in Egypt. Revolution in Tunisia. The Middle East and North Africa face unprecedented change as dictatorships crumble and people clamor for democracy. Yet it remains unclear whether these nations will experience more equity under new regimes. The reshaping of societies raises fundamental questions that require monumental thought. "What the world needs now, especially in these times, is more wisdom," observes Dolores Pushkar, a professor in Concordia's Department of Psychology ...

Sniffing out lymphoma by turning dogs into humans

2011-04-07
Researchers at North Carolina State University are narrowing the search for genes involved in non-Hodgkin lymphoma – by turning dogs into humans. Humans and dogs don't just share companionship and living space, they also share a similar genetic makeup. Additionally, they share the same types of cancer, including lymphoma. Dr. Matthew Breen, professor of genomics at NC State, uses canines as a genetic model for studying lymphoma because purebred dogs of the same breed have less genetic variation among them than humans do, making it easier to pinpoint areas on canine chromosomes ...

Having trouble sharing or understanding emotions? MU researcher believes affection could help
2011-04-07
COLUMBIA, Mo. – Every person has some level of alexithymia, as it is the personality trait which keeps people from sharing or even understanding their own emotions. Now, one University of Missouri researcher's latest study indicates that affectionate communication, such as hugging, could help those who have high levels of alexithymia lead more fulfilling lives. Colin Hesse, an assistant professor of communication in the MU College of Arts and Science, said previous studies estimate 8 to 10 percent of people suffer from high alexithymia. Those who have high alexithymia ...
