Scientists say they have successfully made immature sperm cells from human bone marrow samples.
Nanoparticles improve delivery of medicines and diagnostics
14.4.2007 | Press monitoring
Tiny, biodegradable particles filled with medicine may also contain answers to some of the biggest human health problems, including cancer and tuberculosis. The secret is the size of the package.
Scientists Stop Genes that Help Breast Cancer to Spread
13.4.2007 | Press monitoring
US scientists have demonstrated a way to stop breast cancer spreading to other parts of the body by either switching off the genes involved or blocking them with drugs.
Scientists find rice gene for grain size and yield
13.4.2007 | Press monitoring
Chinese scientists have identified and cloned a rice gene that influences rice grain weight and yield, which could help scientists develop higher yielding varieties of the world's most important food crop.

Bacteria found in the soil activated a group of neurons that produce the brain chemical serotonin.
Nanotextured Implant Materials: Blending in, Not Fighting Back
12.4.2007 | Press monitoring
Texture turns out to be nearly as important as chemistry when designing materials for use in the human body. In two related experiments Brown University engineers Thomas Webster and Karen Haberstroh found that cells responded differently to materials with identical chemistry but different surface textures. On both titanium and polymer materials,...
Sex Of Stem Cells Found Important For Regenerative Medicine
11.4.2007 | Press monitoring
Female stem cells derived from muscle have a greater ability to regenerate skeletal muscle tissue than male cells, according to a study at Children’s Hospital of Pittsburgh of the University of Pittsburgh Medical Center.
Cell Biology: New Connection Between Cancer and Sugars
11.4.2007 | Press monitoring
Every cell in the human body is controlled by signaling networks that are responsive to external stimuli. The stimuli are received by protein receptors on the cell surface. These proteins act as interpreters for cells, receiving messages from the outside and then instructing the cells to divide or to move.
Nanogenerator provides continuous power by harvesting energy from the environment
10.4.2007 | Press monitoring
Researchers have demonstrated a prototype nanometer-scale generator that produces continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow.
Palm oil doesn't have to be bad for the environment
10.4.2007 | Press monitoring
As traditionally practiced in southeast Asia, oil palm cultivation is responsible for widespread deforestation that reduces biodiversity, degrades important ecological services, worsens climate change, and traps workers in inequitable conditions sometimes analogous to slavery.
