Elevated testosterone kills nerve cells
A Yale School of Medicine study shows for the first time that a high level of testosterone, such as that caused by the use of steroids to increase muscle mass or for replacement therapy, can lead to a catastrophic loss of brain cells.   view more (2006-09-27)

Studying glial cells in the roundworm may provide insight into human brain diseases
The key to understanding our brains may lie within a one-millimeter long worm, new research from Rockefeller University indicates. Reporting in the June issue of Developmental Cell, Shai Shaham, Ph.D., and graduate student Elliot Perens use the roundworm, C. elegans, to investigate the mysterious glial cell, which makes up 90 percent of the human... view more...

Researchers discover how stealthy HIV protein gets into cells
Scientists have known for more than a decade that a protein associated with the HIV virus is good at crossing cell membranes, but they didn't know how it worked.   view more (2008-03-18)

Scientists shed light on the mystery of photosynthesis
Scientists at the University of Sheffield are part of an international team that has become the first to successfully discover how the component parts of photosynthesis fit together within the cell membrane. In a paper, The native architecture of a photosynthetic membrane, published in Nature on 26 August 2004, they describe how the configuration... view more... (2004-08-25)

Turn back, wayward axon
To a growing axon, the protein RGMa is a "Wrong Way" sign, alerting it to head in another direction. As Hata et al. demonstrate in the March 9, 2009 issue of the Journal of Cell Biology, translating that signal into cellular action requires teamwork from two receptors.   view more (2009-03-09)

Sleeping sickness parasite shows how cells divide their insides
Graham Warren, professor of cell biology, and his colleagues at Yale study Trypanosoma brucei, the parasite that causes Sleeping Sickness.   view more (2005-11-08)

Study uncovers significant functional differences of novel estrogen receptor
Because of these differences, this new estrogen receptor could become an important therapeutic target and may play a further signaling role in other estrogen target tissues, including uterus and prostate tissues.   view more (2006-06-09)

Making nanoparticles in artificial cells
Two new construction manuals are now available for the world's smallest lamps. Based on these protocols, scientists from the Max Planck Institute of Colloids and Interfaces have tailor-made nanoparticles that can be used as position lights on cell proteins and, possibly in the future as well, as light sources for display screens or for optical... view more...

New structure discovered in butterfly ears
A clever structure in the ear of a tropical butterfly that potentially makes it able to distinguish between high and low pitch sounds has been discovered by scientists from the University of Bristol.   view more (2009-10-22)

Beyond genes: Lipid helps cell wall protein fold into proper shape
A protein that provides a vital passage through a bacterium's outer cell wall will misfold and malfunction if that wall is built of the 'wrong' material, scientists at The University of Texas Medical School at Houston report in a finding that has long-term implications for understanding diseases caused by misfolded proteins such as cystic... view more...

A new method of adult stem cell growth efficacious in treatment of disorders of the cornea
A new method of adult stem cell growth, designed in the Area of Cellular Therapy of the University Clinic (University of Navarra), has demonstrated its efficacy for its capacity to grow cornea stem cells.   view more (2007-07-20)

Researchers identify new, cancer-causing role for protein
The mainstay immune system protein TRAF6 plays an unexpected, key role activating a cell signaling molecule that in mutant form is associated with cancer growth, researchers at The University of Texas M. D. Anderson Cancer Center report in the Aug. 28 edition of Science.   view more (2009-08-28)

Why does aspirin increase the susceptibility of Helicobacter pylori to antimicrobials?
Resent studies reported that aspirin inhibited the growth of H. pylori in a dose-dependent manner and significantly affected the activity of virulence factors of H. pylori.   view more (2009-03-03)

Alzheimer's: New findings resolve long dispute about how the disease might kill brain cells
For a decade, Alzheimer's disease researchers have been entrenched in debate about one of the mechanisms believed to be responsible for brain cell death and memory loss in the illness.   view more (2009-04-16)

When nicotine binds to a neuron, how does the cell know to send the signal that announces a smoker's high"   view more (2007-07-23)

Structural biology scores with protein snapshot
In a landmark technical achievement, investigators in the Vanderbilt Center for Structural Biology have used nuclear magnetic resonance (NMR) methods to determine the structure of the largest membrane-spanning protein to date.   view more (2009-06-26)

New 'self-exploding' microcapsules could take sting out of drug delivery
Belgian chemists have developed "self-exploding" microcapsules that could one day precisely release drugs and vaccines inside the human body weeks or even months after injection.   view more (2006-01-04)

Rockefeller researchers show evidence of asymmetric cell division in mammalian skin
It took almost 10 years for Elaine Fuchs, Ph.D., a Howard Hughes Medical Institute investigator at Rockefeller University, to find a postdoctoral fellow who shared her curiosity for the direction of cell divisions in the skin.   view more (2005-08-17)

Scientists develope a new model of artificial canine skin
Researchers at UNIVET, a spin-off of the Universitat Autònoma de Barcelona, in cooperation with the animal nutrition company Affinity Petcare, have developed an artificial cellular model which faithfully reproduces the characteristics of dog's skin and which will allow, therefore, the carrying out of various lines of research related to... view more...

Synchrotron Sheds Light On Bacteria's Solar Cell
Researchers based at the University of Glasgow, using X-ray data collected at the Synchrotron Radiation Source (SRS) at CCLRC Daresbury Laboratory, have made a major advance in our understanding of the process by which sunlight is converted to food energy, without which life on earth could not exist. The work is published this week (12 December... view more... (2003-12-12)
