[io9] New ‘Senolytic’ Drugs Can Dramatically Increase Healthy Lifespan

Researchers from the Scripps Research Institute and the Mayo Clinic have developed a new class of drugs that were shown to significantly slow the aging process in animal models. The research was only carried out on mice, but the introduction of an entirely new class of drugs, called "senolytics," could have incredible potential for humans as well. The drugs work by selectively targeting and killing senescent cells — older cells that have stopped dividing but are steadily accumulating and contributing to the aging process.

[Science Daily] Some genes ‘foreign’ in origin and not from our ancestors

Many animals, including humans, acquired essential 'foreign' genes from microorganisms co-habiting their environment in ancient times, according to new research. The study challenges conventional views that animal evolution relies solely on genes passed down through ancestral lines, suggesting that, at least in some lineages, the process is still ongoing.

[Nature] Scientists sound alarm over DNA editing of human embryos

Amid rumours that precision gene-editing techniques have been used to modify the DNA of human embryos, researchers have called for a moratorium on the use of the technology in reproductive cells. In a Comment published on 12 March in Nature, Edward Lanphier, chairman of the Alliance for Regenerative Medicine in Washington DC, and four co-authors call on scientists to agree not to modify human embryos — even for research.

[NYTimes] F.D.A. Approves Zarxio, Its First Biosimilar Drug

The Food and Drug Administration has approved the first so-called biosimilar drug for use in the United States, paving the way for less expensive alternatives to an entire class of complex and costly drugs. The approval involves biologic drugs, which are made using living cells and not synthesized from chemicals like typical drugs.
