12-09-24 Shengyuan Yang, Florida Institute of Technology assistant professor of mechanical and aerospace engineering, with graduate student Sang Joo Lee, has published a paper on the first-ever imaging of cells growing on spherical(球形的) surfaces. The pa...
12-08-24 Numerous processes in our body fluctuate(波动,动摇) in a regular pattern during the day. These circadian (or daily) variations can be driven by local oscillators(振荡器) present within our cells or by systemic signals controlled by the master p...
12-08-22 How do stem cells preserve their ability to become any type of cell in the body? And how do they decide to give up that magical state and start specializing? If researchers could answer these questions, our ability to harness stem cells to treat dis...
12-08-02 By identifying a key protein that tells certain breast cancer cells when and how to move, researchers at Michigan State University hope to better understand the process by which breast cancer spreads, or metastasizes(转移,迁徙) . When breast canc...
12-07-13 Fuel cells are inefficient because the catalyst most commonly used to convert chemical energy to electricity is made of the wrong material, a researcher at Case Western Reserve University argues. Rather than continue the futile effort to tweak that...
12-07-04 Toxic chemicals wreak havoc on cells, damaging DNA and other critical molecules. A new study from researchers at MIT and the University at Albany reveals how a molecular emergency-response system shifts the cell into damage-control mode and helps it...
12-06-25 Engineers at the University of Wisconsin-Milwaukee (UWM) have identified a catalyst(催化剂) that provides the same level of efficiency in microbial fuel cells (MFCs) as the currently used platinum catalyst, but at 5% of the cost. Since more than 6...
12-06-21 A cutting-edge method developed at the University of Michigan Center for Arrhythmia Research successfully uses stem cells to create heart cells capable of mimicking the heart's crucial squeezing action. The cells displayed activity similar to most p...
12-06-18 Researchers from the University of Notre Dame have engineered nanoparticles that show great promise for the treatment of multiple myeloma (MM), an incurable cancer of the plasma(浆细胞) cells in bone marrow. One of the difficulties doctors face in...
12-06-06 A new model for understanding how nerve cells in the brain control movement may help unlock the secrets of the motor cortex(运动皮质) , a critical region that has long resisted scientists' efforts to understand it, researchers report June 3 in Nat...
