mouse embryonic stem cells

While You Were At the Bench: Week 40

It’s been a busy week for scientists, but here are some of the highlights.

Contrary to the belief that retracted journal articles are due to simple errors, a recent PNAS article found that 67.3% of retracted journal articles are due to fraudulent data.  Com’n people.  We’re better than this!

Columbia University ophthalmologists used human induced pluripotent stem cells to improve the vision of blind mice.  This approach may be useful for restoring vision in humans with macular degeneration and other retinal deficits.

Kyoto University researchers successfully used mouse embryonic stem cells to develop oocytes that produced viable offspring once fertilized and implanted into a surrogate mother.   This method could lead to new infertility therapies but raises potential ethical and legal issues.

Where’s Nemo?  A study conducted by the Australian Institute of Marine Science has determined the Great Barrier Reef has lost half of its coral in the last 27 years.  The contributors?  Cyclones (48%), Crown-of-Thorns Starfish (42%) and Bleaching (10%).

By measuring different isotopes of Carbon from ice core samples obtained in Greenland, researchers have determined the amount of methane produced by humans in the last 2000 years.  Human sources of methane production has increased dramatically since the start of industrial revolution in the 1800′s.

Has the Curiosity Rover discovered an ancient riverbed on Mars?  The photos look rather convincing.

In a follow-up to a previous blog regarding genetically modified food, the European Food Safety Authority has determined that a French study supporting the toxic effects of genetically modified corn was poorly designed and therefore does not support the conclusions made in the paper.  The authors have until October 12th to address concerns raised by the agency.

Geologists are attempting to drill 6 kilometers beneath the Pacific Ocean sea floor to obtain the first ever sample of the Earth’s mantle.  Maybe they can retrieve Brendan Fraser’s acting career while they are down there.  Zing!

Have a great weekend.
