Special E.Coli Bacteria Produce Diesel on Demand
TEHRAN (FNA)- It sounds like science fiction but a team from the University of Exeter, with support from Shell, has developed a method to make bacteria produce diesel on demand. ( 10:18:58 - 2013/04/23)

Stem Cell Transplant Restores Memory in Mice
TEHRAN (FNA)- For the first time, human embryonic stem cells have been transformed into nerve cells that helped mice regain the ability to learn and remember. ( 10:06:44 - 2013/04/23)

Zinc Oxide, Hydroxide Nanoparticles Utilized in Detecting Drugs
TEHRAN (FNA)- Researchers at Payam-e-Noor University of Tehran in collaboration with experts from Tabriz University of Medical Sciences found a simple synthesis method for zinc oxide (and hydroxide) and their application in modified carbon paste electrodes for determination of sympathomimetic drugs at micro-molar scales. ( 14:02:29 - 2013/04/22)

Risk Factor for Depression Can Be 'Contagious'
TEHRAN (FNA)- A new study with college roommates shows that a particular style of thinking that makes people vulnerable to depression can actually "rub off" on others, increasing their symptoms of depression six months later. ( 10:14:56 - 2013/04/22)

Gene Regulates Heart's Ability to Regenerate After Injuries
TEHRAN (FNA)- Researchers at UT Southwestern Medical Center have identified a specific gene that regulates the heart's ability to regenerate after injuries. ( 10:13:57 - 2013/04/22)

Scientists Probe Source of Pulsing Signal in Sleeping Brain
TEHRAN (FNA)- New findings clarified where and how the brain's "slow waves" originate. These rhythmic signal pulses, which sweep through the brain during deep sleep at the rate of about one cycle per second, are assumed to play a role in processes such as consolidation of memory. ( 09:33:53 - 2013/04/21)

Neural Activity in Bats Measured In-Flight
TEHRAN (FNA)- New research revealed for the first time how three-dimensional, volumetric, space is perceived in mammalian brains. ( 09:32:49 - 2013/04/21)

Multi-Walled Carbon Nanotubes Used in Producing DNA Biosensors
TEHRAN (FNA)- Iranian researchers from Alzahra University produced an electrochemical DNA biosensor by studying interactions between antimicrobial drug and double stranded DNA on the surface of glassy carbon electrode modified with multi-walled carbon nanotube (MWCNT-DNA-GCE). ( 14:44:31 - 2013/04/20)

Technique Unlocks Design Principles of Quantum Biology
TEHRAN (FNA)- University of Chicago researchers have created a synthetic compound that mimics the complex quantum dynamics observed in photosynthesis and may enable fundamentally new routes to creating solar-energy technologies. ( 10:41:55 - 2013/04/20)

Ethnicity May Influence Antibody Genes
TEHRAN (FNA)- Cracking the DNA code for a complex region of the human genome has helped 14 North American scientists, including five at Simon Fraser University, chart new territory in immunity research. ( 10:24:14 - 2013/04/20)

Super-Earth Planets Found in "Habitable Zone"
TEHRAN (FNA)- Scientists discovered two new planetary systems that include three super-Earth-size planets in the "habitable zone", the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water. ( 12:15:20 - 2013/04/19)

Study: Learning Disabilities Affect Up to 10 Percent of Children
TEHRAN (FNA)- Up to 10 percent of the people are affected by specific learning disabilities (SLDs), such as dyslexia, dyscalculia and autism, translating to 2 or 3 pupils in every classroom, a new study suggested. ( 11:53:30 - 2013/04/19)

Production of Ethanol Gas Sensor Based on Carbon Nanotube Nanocomposite
TEHRAN (FNA)- Iranian researchers used a new casting method to produce polymeric nanoparticles casted by ethanol molecules in order to detect ethanol gas. ( 10:18:19 - 2013/04/18)

Hair Analysis Reveals Elevated Stress Hormone Levels Raise Cardiovascular Risk
TEHRAN (FNA)- Findings of a new study revealed that hair strands contain valuable information about senior citizens' stress levels that can be used to determine an individual's cardiovascular disease risk. ( 09:27:36 - 2013/04/18)
