In order to maintain muscle strength with age, cells must rid themselves of the garbage that accumulates in them over time, just as it does in any household.
A powerful new breast cancer treatment could result from packaging one of the newer drugs that inhibits cancer's hallmark wild growth with another that blocks a primordial survival technique in which the cancer cell eats part of itself, researchers say.
Meiosis â€“ the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell â€“ is a major crossroads in all organisms reproducing sexually.
US geneticists say that for the first time ever they have successfully managed to induce human embryonic stem cells to transform into germ cells capable of producing egg and sperm cells.
When mother and daughter cells are created each time a cell divides, they are not exactly alike.
Recent data have indicated that the more brown fat cells a person has the lower their body mass.
A Florida State University College of Medicine researcher has solved a century-old mystery about proteins that play a vital role in the transfer of the human genetic code from one cell to another. The discovery could lead to finding new ways to help the body fight a variety of diseases, including cancer.
When it comes to the two basic types of cells, prokaryotes and eukaryotes, compartmentalization is everything. Prokaryotes are evolutionarily ancient cells that only have a membrane surrounding their outer boundary, while the more complex eukaryotes have an outer membrane and membrane bound compartments within the cell. Perhaps most notable is the double layered membrane that surrounds the nucleus, the cellular compartment which houses the cell's genetic material.
A Purdue University researcher has discovered that the absence of certain proteins needed for proper cell duplication can lead to cancer.
For years, health conscious people have been taking antioxidants to reduce the levels of reactive oxygen in their blood and prevent the DNA damage done by free radicals, which are the result of oxidative stress. But could excessive use of antioxidants deplete our immune systems?
