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 »

Chinese scientists give monkeys human brain genes in ‘morally risky’ experiment

Their brains may not be bigger than normal, but monkeys created with human brain genes are exhibiting cognitive changes that suggest they might be smarter — and the experiments have ethicists shuddering. In the wake of the genetically modified human babies scandal, Chinese scientists are drawing fresh condemnation from philosophers and ethicists, this time over… Read More »

Human health can be ‘mostly sustained’ for a year in space, NASA Twins Study concludes

The majority of changes that occurred in Kelly’s body, compared with his identical brother, Mark, on Earth, returned to normal once he came back from the space station. The study results suggest that human health can be “mostly sustained” for a year in space, the researchers said. On a call with reporters Thursday, Mark thanked… Read More »

NASA’s landmark Twins Study reveals resilience of human body in space

Results from NASA’s landmark Twins Study, which took place from 2015-2016, were published Thursday in Science. The integrated paper — encompassing work from 10 research teams — reveals some interesting, surprising and reassuring data about how one human body adapted to — and recovered from — the extreme environment of space. The Twins Study provides… Read More »
