Crispr Gene Editing Can Cause Unwanted Changes in Human Embryos, Study Finds

A powerful gene-editing tool called Crispr-Cas9, which this month nabbed the Nobel Prize in Chemistry for two female scientists, can cause serious side effects in the cells of human embryos, prompting them to discard large chunks of their genetic material, a new study has found. Administered to cells to repair a mutation that can cause… Read More »

Intestinal Organoids Mimic Human Gut

Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have developed a mini intestine on a chip that closely mimics the morphology and cellular composition of the small intestine. The device could be useful for advancing personalized medicine, drug screening, and even paving the way for researchers to grow new tissues and organs in… Read More »

Human Sperm Stem Cells Grown in Lab, an Early Step Toward Infertility Treatment

Infertility affects one in seven men of reproductive age worldwide. One idea for treating male sterility is spermatogonial stem cell (SSC) therapy. In this approach, sperm stem cells in the testis are transferred to a test tube, cultured and nudged into becoming fully fledged sperm. However, a key bottleneck has been identifying just the right… Read More »

Human knee evolved in lockstep with osteoarthritis, Harvard study says

The human knee is a triumph of design. The joint, which evolved fairly rapidly from our common ancestor with the chimpanzee to accommodate bipedalism, likely contributed to our success as a species. However, as the human lifespan extended, the flaw in the design emerged: pain, in the form of osteoarthritis. In a new paper published… Read More »

New method to grow human blood vessels

A team of researchers at the University of Minnesota Medical School recently proved the ability to grow human-derived blood vessels in a pig — a novel approach that has the potential for providing unlimited human vessels for transplant purposes. Because these vessels were made with patient-derived skin cells, they are less likely to be rejected… Read More »

Revealing the new face of a 3.8-million-year-old early human ancestor

This is the first time a skull belonging to Australopithecus anamensis has been found and the discovery sheds light on the evolutionary history of early human ancestors. Researchers have been working on the Woranso-Mille Paleoanthropological Research Project study in the Afar Regional State of Ethiopia for 15 years. On February 16, 2016, the upper jaw… Read More »
