CAMBRIDGE, MA -- MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of generations. The circuits, described in the Feb. 10 online edition of Nature Biotechnology, could be used as long-term environmental sensors, efficient controls for biomanufacturing, or to program stem cells to differentiate into other cell types. "Almost all of the previous work in synthetic biology that we're aware of has either focused on logic components ...

This press release is available in Spanish. Learning more about the behavior of bed bugs is one approach being used by U.S. Department of Agriculture (USDA) scientists to identify compounds to help control these pests. The resurgence of bed bugs over the last decade has caused problems in major U.S. cities where they infest homes, apartments, hotels, shelters and even places of work. The small, blood-feeding insects are not known to transmit diseases, but they can cause severe reactions in people who are allergic to them. Bed bugs usually go unnoticed until their numbers ...

By combining low temperatures and NMR spectroscopy, the scientists visualized seven intermediate forms of the CylR2 protein while cooling it down from 25°C to -16°C. Their results show that the most instable intermediate form plays a key role in protein folding. The scientists' findings may contribute to a better understanding of how proteins adopt their structure and misfold during illness. Whether Alzheimer's, Parkinson's or Huntington's Chorea – all three diseases have one thing in common. They are caused by misfolded proteins that form insoluble clumps in the brains ...

Parents, teachers and psychologists know boys and girls behave differently. However, that difference isn't taken into account by most methods used to assess the risk to children from chemical exposure, according to Cheryl Rosenfeld, associate professor of biomedical sciences in the University of Missouri's Bond Life Sciences Center. A series of experiments by Rosenfeld studied the effects of prenatal exposure to bisphenol A (BPA) on later reproductive-associated behaviors using a socially and genetically monogamous rodent, the California mouse, which may better mirror most ...

Lead is a common element but is found in old paints (including those once used on children's toys), soil, old piping, water, and the atmosphere from lead-containing vehicular fuels, even drinking vessels. At high dose it is lethal but also causes seemingly trivial symptoms such as headaches. However, in children lead can also lead to irreversible damage to the organs, the kidneys in particular, and the nervous system including the brain. Early detection to contaminated sources is important to prevent children coming to harm but exposure is not always apparent. The effects ...
