Scientists take first step towards creating ’inorganic life’
Lee Cronin [mp4] Scientists at the University of Glasgow say they have taken their first tentative steps towards creating 'life' from inorganic chemicals potentially defining the new area of 'inorganic biology'. Professor Lee Cronin, Gardiner Chair of Chemistry in the College of Science and Engineering, and his team have demonstrated a new way of making inorganic-chemical-cells or iCHELLS.

Drug regulations work to cut 'ice' use
Drug regulations work to cut ‘ice’ use
Regulations that control chemicals used to make the drug 'ice' work, but they come at a cost, according to new research published today in the journal Addiction. Lead author Rebecca McKetin from the Centre for Mental Health Research at The Australian National University said the paper reviewed the results of credible studies on the impacts of what are known as 'precursor regulations'.

Profiler at the cellular level
Researchers have successfully incorporated a diagnostic biological "computer" network in human cells. This network recognizes certain cancer cells using logic combinations of five cancer-specific molecular factors, triggering cancer cells destruction. Yaakov (Kobi) Benenson, from ETH Zurich, has spent a large part of his career developing biological computers that operate in living cells.

Ultrasensitive particles offer new way to find cancer
Tiny particles that measure microRNA levels in tissue samples could help diagnose and monitor many diseases. CAMBRIDGE, Mass. ' About 10 years ago, scientists discovered a new type of genetic material called microRNA, which appears to turn genes on or off inside a cell. More recently, they found that these genetic snippets often go haywire in cancer cells, contributing to tumors' uncontrollable growth.

Flame retardants linked to lower birthweight babies
Flame retardants linked to lower birthweight babies
Exposure during pregnancy to flame retardant chemicals commonly found in the home is linked to lower birthweight babies, according to a new study led by researchers at the University of California, Berkeley's School of Public Health. In the study, to appear Tuesday, Aug. 30, in the peer-reviewed publication American Journal of Epidemiology , researchers found that every tenfold increase in levels of PBDEs, or polybrominated diphenyl ethers, in a mother's blood during pregnancy corresponded to a 115 gram (4.1 ounce) drop in her baby's birthweight.

New theory may shed light on dynamics of large-polymer liquids
New theory may shed light on dynamics of large-polymer liquids
CHAMPAIGN, Ill. A new physics-based theory could give researchers a deeper understanding of the unusual, slow dynamics of liquids composed of large polymers. This advance provides a better picture of how polymer molecules respond under fast-flow, high-stress processing conditions for plastics and other polymeric materials.

Faster organic semiconductors for flexible displays can be developed quickly with new method
Organic semiconductors hold immense promise for use in thin film and flexible displays - picture an iPad you can roll up - but they haven't yet reached the speeds needed to drive high definition displays. Inorganic materials such as silicon are fast and durable, but don't bend, so the search for a fast, durable organic semiconductor continues.

Nano Gold Rush: Researchers use tiny gold particles to boost organic solar cell efficiency
Nano Gold Rush: Researchers use tiny gold particles to boost organic solar cell efficiency
In the world of solar energy, organic photovoltaic solar cells have a wide range of potential applications, but they are still considered an upstart. While these carbon-based cells, which use organic polymers or small molecules as semiconductors, are much thinner and less expensive to produce than conventional solar cells made with inorganic silicon wafers, they still lag behind in their ability to efficiently convert sunlight into electricity.

Carbon nanotube structures changed by ’attack’ from within, researchers discover
A team of researchers has shown for the first time that chemical reactions at the nano-level which change the structure of carbon nanotubes can be sparked by an 'attack' from within. The discovery challenges previous scientific thinking that the internal surface of the hollow nanostructures is chemically unreactive, largely restricting their use to that of an inert container or a 'nano-reactor' inside which other chemical reactions can take place.

Honeycomb Carbon Crystals Possibly Detected in Space
Honeycomb Carbon Crystals Possibly Detected in Space
NASA's Spitzer Space Telescope has spotted the signature of flat carbon flakes, called graphene, in space. If confirmed, this would be the first-ever cosmic detection of the material - which is arranged like chicken wire in flat sheets that are one atom thick. Graphene was first synthesized in a lab in 2004, and subsequent research on its unique properties garnered the Nobel Prize in 2010.

New treatment option for advanced prostate cancer
Prostate cancer that has become resistant to hormone treatment and that does not respond to radiation or chemotherapy requires new methods of treatment. By attacking stem cell-like cells in prostate cancer, researchers at Lund University are working on a project to develop a new treatment option.

Alien World is Blacker than Coal
Alien World is Blacker than Coal
Cambridge, MA - Astronomers have discovered the darkest known exoplanet - a distant, Jupiter-sized gas giant known as TrES-2b. Their measurements show that TrES-2b reflects less than one percent of the sunlight falling on it, making it blacker than coal or any planet or moon in our solar system. "TrES-2b is considerably less reflective than black acrylic paint, so it's truly an alien world," said astronomer David Kipping of the Harvard-Smithsonian Center for Astrophysics (CfA), lead author on the paper reporting the research.

Tracking Manmade Biofuels in Atmosphere
Tracking Manmade Biofuels in Atmosphere
Scientists have discovered a technique to track urban atmospheric plumes, thanks to a unique isotopic signature found in vehicle emissions. Brian Giebel, a marine and atmospheric chemistry graduate student working with University of Miami researchers Daniel Riemer and Peter Swart, discovered that ethanol mixed in vehicle fuel is not completely burned, and that ethanol released in the engine's exhaust has a higher 13C to 12C ratio when compared to natural emissions from most living plants.
