Nearly 90-percent of all human cancers involve epithelial cells.  The TGF- protein plays a major role in controlling the growth and differentiation of epithelial cells, sending a signal that stops their unchecked growth.  In a paper published in Science, a research team led by Kunxin Luo has shown that two closely related proteins, long suspected of being major contributors to the development of a number of cancers, interact with another family of proteins to completely shut down the TGF- signal.



In the field of superconductivity, the holy grail for the past 14 years has been room-temperature superconductors.  Room-temperature superconductors potentially could create a new world of dirt-cheap electrical power and magnetically levitated high-speed trains.  No one knows the recipe for making such materials nor is the physics underlying high-temperature superconductivity fully understood.  In a paper published in Nature on February 17, researchers detail new insights into the atomic-level mechanisms underlying high-temperature superconductivity.



Berkeley Lab researchers have connected two cyclotrons here, crafting a relatively simple and inexpensive means of studying nuclear reactions in which one of the reaction partners is radioactive.  Researchers are now able to further explore the mechanisms of energy production in the stars, which depend upon short-lived isotopes like those that can be produced by the new BEARS project.

  



Radioactive radon gas, seeping into homes from the ground, poses a major health risk in certain parts of the U.S. The new Radon Project Web site calculates the probable level of exposure in your home as well as the risk of lung cancer and then recommends whether you should pay for actual measurements and/or remediation.

Improved magnetic devices such as the read heads of computer hard drives could result from new insights into antiferromagnetic thin films
