A major hub for cell-fate decisions
In a recently published study, LMU researchers show that, in a nerve-cell lineage in the nematode Caenorhabditis elegans, a single protein controls the rate of cell-cycle progression, and decides whether cells divide, differentiate ...

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 that, and now researchers ...

Researchers use magnets to cause programmed cancer cell deaths
(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 of the magnetic field, ...
Lace plants explain programmed cell death
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 ...

Study shows vast majority of cells close to death after toxin exposure can survive and thrive
(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 a new study. The ...

New strategy directly activates cellular 'death protein'
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 ...

When dying, bacteria share some characteristics with higher organisms
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 ...

Inhaled nanoparticles deliver potent anticancer cocktail to lung tumors and block resistance
(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 ...
