Needling Chromosomes Reveals Cell Division Secret

...er, then onereplicated chromatid can attach to one pole and the other to theopposite pole. But if they are not held together, they attachindependently, and often both sister chromatids can go to the same polerather than to opposite poles. This creates chromosome imbalances thatcan lead to cancer or chromo...

Microbial fuel cell: High yield hydrogen source and wastewater cleaner

... applied to the circuit by connecting the positive pole of a programmable power supply to the anode and the negative pole to the cathode. The researchers call their hydrogen-producing MFC a BioElectrochemically-Assisted M...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

...he Earth's polarity today. Since the last magnetic pole reversal was 790,000 years ago, the rock must be at least that age. Because the Earth's magnetic polarity changes, on average, every 250,000 years, the argon/argon date is consistent with a time between 1.07 and 1.77 million years ago when the Earth'...

Salk scientists get to the root of plant cell fate

... know how a plant can set aside a root and a shoot pole during embryogenesis and keep these functions separate," Long says. The researchers found that the TOPLESS gene encodes a protein (TOPLESS) that is a transcriptional co-repressor. In plants and animals, co-repressors regulate gene expression by inhi...

The power of one: A simpler, cheaper method for cell fusion

...a miniscule gap that channels electricity from one pole to the other. Passing through this narrow section, cells are subjected to a strong electrical field that causes them to become destabilized and fuse together. In one of electrofusion's applications, scientists can fuse antibody-producing cells fro...
