Stem cells used to model infant birth defect
Hemangiomas -- strawberry-like birthmarks that commonly develop in early infancy -- are generally harmless, but up to 10 percent cause tissue distortion or destruction and sometimes obstruction of vision or breathing. |

Study Highlights Forest Protected Areas as a Critical Strategy for Slowing Climate Change
The authors highlight analyses showing that since 2002, deforestation in the Brazilian Amazon has been 7 to 11 times lower inside of indigenous lands and other protected areas than elsewhere. Simulation models suggest that protected areas established between 2003 and 2007 could prevent an estimated area of 100,000 square miles of deforestation through 2050. |

Vitamin D crucial to activating immune defenses
For T cells to detect and kill foreign pathogens such as clumps of bacteria or viruses, the cells must first be triggered into action and transform from inactive and harmless immune cells into killer cells that are primed to seek out and destroy all traces of a foreign pathogen. |

MIT researchers discover new way of producing electricity
A team of scientists at MIT have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity, the researchers say. |

MIT scientists transform polyethylene into a heat-conducting material
Most polymers materials made of long, chain-like molecules are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, into a material that conducts heat just as well as most metals, yet remains an electrical insulator. |
