Summary:
The discovery of a novel cellular “switch” in the popular laboratory research worm, C. elegans, by a University of Colorado at Boulder team may provide researchers with a new means of triggering programmed cell death in humans to treat disease.
A research team led by the University of Colorado at Boulder has discovered a previously unknown cellular "switch" that may provide researchers with a new means of triggering programmed cell death, findings with implications for treating cancer.
The new results are a big step forward in understanding programmed cell death, or apoptosis, a cell suicide process that involves a series of biochemical events leading to changes like cell body shrinkage, mitochondria destruction and chromosome fragmentation, said CU-Boulder Professor Ding Xue. But unlike traumatic cell death from injury, programmed cell death is a naturally occurring aspect of animal development that may help prevent human diseases like cancer and autoimmune disorders, said Xue, lead author on the new study.

Discovery Of Cell Linked To Learning And Memory
Source: University of Queensland
Date: May 14, 2008
Summary:
Queensland Brain Institute (QBI) neuroscientists at The University of Queensland have discovered a fundamental component of the process that regulates memory formation. The discovery explains, for the first time, how new nerve cells form in an area of the brain associated with learning and memory – which is known to deteriorate in people with stroke and dementia.

Structure Reveals How Cells 'Sugar-coat' Proteins
Source: Brookhaven National Laboratory
Date: March 11, 2008
Summary:
Biologists at the U.S. Department of Energy's Brookhaven National Laboratory, Stony Brook University, and the University of Wurzburg, Germany, have deciphered the structure of a large protein complex responsible for adding sugar molecules to newly formed proteins - a process essential to many proteins' functions. The structure offers insight into the molecular "sugar-coating" mechanism, and may help scientists better understand a variety of diseases that result when the process goes awry.

Date; January 17, 2008
Summary:
By piecing together the detailed structure of a molecule-munching enzyme, researchers from the Howard Hughes Medical Institute (HHMI) have revealed how it helps maintains cells' internal highways. The finding could one day lead to new treatments for a neurological disorder caused when the enzyme, known as spastin, malfunctions.

Patch Helps Heart Grow New Cells
Source: HealthDay News
Date: July 16, 2007
Summary:
HealthDay News reports on the development of a special patch to regenerate damaged heart tissue after a heart attack:
"A special patch placed on a damaged area of the heart regenerates cardiac cells after heart attack and improves heart function, a new study finds. Success with the patch in rats may lead the way to new methods of repairing damaged human hearts and possibly spare some patients the need for a heart transplant, according to researchers reporting in the July 15 online edition of Nature Medicine."

Can heart tissue be regenerated? Mature heart cells, given the right environment, can replicate
Source: Children's Hospital Boston
Date: July 15, 2007
Summary:
When human hearts are injured, as during a heart attack, healthy tissue normally can’t regrow. Researchers now demonstrate in rats that a sponge-like patch, soaked in a compound called periostin and placed over the injury, can not only get heart cells to begin dividing and making copies of themselves again, but also improves heart function. Their findings appear in the July 15 online edition of Nature Medicine.

Posted: March 3, 2006
Summary:
A mouse immune cell that plays dual roles as both assassin and messenger, normally the job of two separate cells, has been discovered by an international team of researchers from the United States and France. The discovery has triggered a race among scientists to find a human equivalent of the multitasking cell, which could one day be a target for therapies that seek out and destroy cancer.

Custom-Made Microbes, at Your Service
Source: New York Times
Date: January 17, 2006
Summary:
There are bacteria that blink on and off like Christmas tree lights and bacteria that form multicolored patterns of concentric circles resembling an archery target. Yet others can reproduce photographic images. While much of the early work has consisted of eye-catching, if useless, stunts like the blinking bacteria, the emerging field could one day have a major impact on medicine and industry. For instance, Christina D. Smolke, an assistant professor at the California Institute of Technology, is trying to develop circuits of biological parts to sit in the body's cells and guard against cancer. If they detected a cancer-causing mechanism had been activated, they would switch on a gene to have the cell self-destruct.

Summary:
In experiments with mice, scientists from Johns Hopkins' Institute for Cell Engineering have discovered the steps required to integrate new neurons into the brain's existing operations. In the first study to show how these "baby" neurons are integrated into the brain's existing networks, the Johns Hopkins researchers show that a brain chemical called GABA readies baby neurons to make connections to old ones.

Scientists create hybrid cell
Source: Knight Ridder Newspapers
Posted: August 27, 2005 07:50 PM
Summary:
A team of scientists at Harvard have fused skin cells with embryonic stem cells to create a hybrid cell. The new cell can be "reprogrammed" to become a different kind of cell. The new technology may lead to new ways to produce insulin, which could benefit diabetics, regenerate nerves, which could help paralyzed people walk again, and could be used to stave off degenerative diseases such as Parkinson's.
