Martian Clay Contains Chemical Implicated in the Origin of Life, Astrobiologists Find
June 10, 2013 — Researchers have discovered high concentrations of boron in a Martian meteorite. When present in its oxidized form (borate), boron may have played a key role in the formation of RNA, one of the ... > full story -
From Hot Springs to HIV, Same Protein Complexes Are Hijacked to Promote Viruses
June 10, 2013 — Biologists have discovered a striking connection between viruses such as HIV and Ebola and viruses that infect organisms called archaea that grow in volcanic hot springs. Despite the huge difference ... > full story -
How Does Inbreeding Avoidance Evolve in Plants?
June 10, 2013 — Inbreeding is generally deleterious, even in flowering plants. Since inbreeding raises the risk that bad copies of a gene will be expressed, inbred progeny suffer from reduced viability. A case study ... > full story -
Hairpin Turn: Micro-RNA Plays Role in Wood Formation
June 10, 2013 — Scientists have found the first example of how micro-RNA regulates wood formation inside plant cells and mapped out key relationships that control the ... > full story -
Epigenetic Factor Likely Plays a Key Role in Fueling Most Common Childhood Cancer
June 10, 2013 — Changes in an epigenetic mechanism that turns expression of genes on and off may be as important as genetic alterations in causing pediatric acute lymphoblastic leukemia, according to a new ... > full story -
Master Regulator in Cancer Metastasis Discovered
June 10, 2013 — In the process of metastasis, the movement of cancer cells to different parts of the body, a specific master regulator gene plays a central role: a transcription factor named Sox4 activates a ... > full story -
Self-Fertilizing Plants Contribute to Their Own Demise
June 10, 2013 — Many plants are self-fertilizing, meaning they act as both mother and father to their own seeds. This strategy -- known as selfing -- guarantees reproduction but, over time, leads to reduced ... > full story -
Ötzi the Iceman's Dark Secrets: Protein Investigation Supports Brain Injury Theory
June 10, 2013 — After decoding the Iceman's genetic make-up, a research team has now made another major breakthrough in mummy research: Using just a pinhead-sized sample of brain tissue from the world-famous glacier ... > full story -
Duck Genome Provides New Insight Into Fighting Bird Flu
June 9, 2013 — The duck genome consortium has completed the genome sequencing and analysis of the duck (Anas platyrhynchos), one principal natural host of influenza A viruses, which caused a new epidemic in China ... > full story -
Rare Mitochondrial Mutations – Maybe Not So Rare? Comprehensive Analysis of Mitochondrial DNA Will Aid Early Diagnosis
June 8, 2013 — Scientists have discovered that supposedly rare mutations in the mitochondria, the ‘power plants’ of human cells responsible for creating energy, account for more than 7% of patients with ... > full story
