At the American Heart Association's Scientific Sessions 2012, a study showed that genetically engineered tomato plants produced a peptide that mimics the actions of good cholesterol when eaten 

In the study, mice that ate the freeze-dried, ground tomatoes had less inflammation and reduced atherosclerosis, plaque build-up in the arteries. 

An experimental device converts kinetic energy from beating hearts into electricity than can power a pacemaker, meaning the chance for no more batteries in the future, according to a talk at the American Heart Association's Scientific Sessions 2012.

The study is preliminary but a piezoelectric approach is promising for pacemakers because they require only small amounts of power to operate. Batteries must be replaced every five to seven years, which is costly and inconvenient.  Piezoelectricity might also power other implantable cardiac devices like defibrillators, which also have minimal energy needs.

We're not that special, says new research led by the Centre for Star and Planet Formation at the Natural History Museum of Denmark, University of Copenhagen.

About 4.567 billion years ago, our solar system's planets spawned from an expansive disc of gas and dust rotating around the sun. While similar processes are witnessed in younger solar systems throughout the Milky Way, the formative stages of our own solar system were believed to have taken twice as long to occur. It turns out that is not the case, according to a new paper.

Perhaps China could use some genetically modified food.  Otherwise, meeting the food demands of 22 percent of the world's population while maintaining their over-reliance on nitrogen-based fertilizer will continue to dramatically increase their emissions of nitrous oxide (N₂O) – the most potent greenhouse gas. 

Medivir AB has announced plans for a phase II proof-of-concept study of an all-oral regimen for the treatment of hepatitis C containing of Medivir/Janssen's protease inhibitor simeprevir and Vertex's nucleotide analogue hepatitis C virus (HCV) polymerase inhibitor VX-135. Janssen will conduct a drug-drug interaction study with simeprevir and VX-135 to support the planned initiation of a phase II proof-of-concept study in early 2013, pending discussions with regulatory authorities. 

Keryx Biopharmaceuticals, Inc. has announced the initiation of a Phase 2 study of Zerenex (ferric citrate), an ferric iron-based phosphate binder drug candidate, in managing serum phosphorus and iron deficiency in anemic patients with Stage 3 to 5 non-dialysis dependent chronic kidney disease ("NDD-CKD").

In the United States alone, over one and a half million people suffering from Stages 3 to 5 NDD-CKD have iron deficiency anemia, however, there are currently no oral iron supplements with an FDA label in NDD-CKD. Also, there are currently no FDA approved phosphate binders in NDD-CKD.
