How birds lost their penises
In animals that reproduce by internal fertilization, as humans do, you'd think a penis would be an organ you couldn't really do without, evolutionarily speaking. Surprisingly, though, most birds do exactly ...

Apoptosis is a programmed death mechanism that eliminates unwanted or injured cells from the body. Defects in apoptotic regulation can lead to serious physiological problems such as tissue damage or uncontrolled ...
A previously poorly investigated signalling pathway is crucial for the growth and proliferation of prostate cancer cells. An international research team discovered this when studying the enzyme "soluble adenylyl ...
(Phys.org)—A team of researchers in South Korea has developed a method to cause cell death in both living fish and lab bowel cancer cells (in vivo and in vitro) using a magnetic field. The application o ...
Scientists from the Spanish National Cancer Research Centre (CNIO) describe how natural selection also occurs at the cellular level, and how our body's tissues and organs strive to retain the best cells in their ranks in ...
Programmed cell death (PCD) is a highly regulated process that occurs in all animals and plants as part of normal development and in response to the environment. New research published in BioMed Central's open access journal ...
(Phys.org) -- Israeli researchers have identified a new mechanism for inducing the programmed death of cells, a discovery that could be used to develop novel methods for treating cancer.
(Phys.org) -- The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in ...
Researchers at Dana-Farber/Children's Hospital Cancer Center have devised a strategy to directly activate a natural "death" protein, triggering the self-destruction of cells. They say the development could represent a new ...
Do bacteria, like higher organisms, have a built-in program that tells them when to die? The process of apoptosis, or cell death, is an important part of normal animal development. In a new study published March 6 in the ...
(PhysOrg.com) -- An international team of biochemists, biophysicists, and neutron scientists are using a combination of fluorescence and small-angle neutron scattering (SANS) techniques to assist biochemists ...
(PhysOrg.com) -- An ideal treatment for lung cancer would be one that could be inhaled deep into lung tissue where it would deliver tumor-killing agents that would then largely stay in the lungs, avoiding the toxicities that ...
Researchers from the Walter and Eliza Hall Institute have found a structural surprise in a type of protein that encourages cell survival, raising interesting questions about how the proteins function to influence ...
Researchers demonstrate for the first time that programmed cell death - a process by which cells deliberately destroy themselves - is involved in mandibular regression in termites. And it appears this regression may be the ...
When cells find themselves in a tight spot, the cell cycle regulator p21 halts the cell cycle, buying cells time to repair the damage, or if all else fails, to initiate programmed cell death. In contrast to other stress-induced ...
