In Early Earth, Iron Helped RNA Catalyze Electron Transfer
A new study shows how complex biochemical transformations may have been possible under conditions that existed when life began on the early Earth. The study shows that RNA is capable of catalyzing electron transfer under conditions similar to those of the early Earth. |

Zinc: The Goldilocks Metal for Bioabsorbable Stents?
Some materials dissolve too quickly, before cardiac arteries can fully heal, and some hang around forever. Zinc, however, may be just right. |

Research On Cilia Heats Up: Implications For Hearing, Vision Loss And Kidney Disease
Experiments at Johns Hopkins have unearthed clues about which protein signaling molecules are allowed into hollow, hair-like “antennae,” called cilia, that alert cells to critical changes in their environments. |

Unique Sulfur Isotopes in Plume Lavas Reveal Deep Mantle Storage of Archean CrustAn international team of researchers, led by scientists at Boston University’s Department of Earth and Environment, has found evidence that material contained in young oceanic lava flows originated at the Earth’s surface in the Archean (>2.45 billions years ago). The new finding helps constrain the timing of the initiation of plate tectonics, the origin of some of the chemical heterogeneity in the Earth’s mantle, and may shed light on how the chaotically convecting mantle could preserve such material for so long. The study appears in the April 25 issue of the journal Nature |

Geoscientists Predict New Compounds Could Change Our View of What Planets are Made Of
A team of researchers led by Artem R. Oganov, a professor of theoretical crystallography in the Department of Geosciences, has made a startling prediction that challenges existing chemical models and current understanding of planetary interiors — magnesium oxide, a major material in the formation of planets, can exist in several different compositions. The team’s findings, “Novel stable compounds in the Mg-O system under high pressure,” are published in the online edition of Physical Chemistry Chemical Physics. The existence of these compounds — which are radically different from traditionally known or expected materials — could have important implications. |

Fertilizer That Fizzles in a Homemade Bomb Could Save Lives Around the WorldA Sandia Labs engineer who trained U.S. soldiers to avoid improvised explosive devices (IEDs) has developed a fertilizer that helps plants grow but can’t detonate a bomb. It’s an alternative to ammonium nitrate, an agricultural staple that is also the raw ingredient in most of the IEDs in Afghanistan. |

The Human Immune System in SpaceWhen the space shuttle Atlantis touched down in the summer of 2011 at Cape Canaveral, closing the book on the U.S. shuttle program, a team of U.S. Army researchers stood at the ready, eager to get their gloved hands on a small device in the payload that housed a set of biological samples. On Monday at the Experimental Biology 2013 conference in Boston, the team will present the results of nearly two years’ worth of study on those samples, results that shed light on how the human immune system responds to stress and assaults while in space – and maybe here on Earth. |
