LAKE WORTH, Florida, February 22 /PRNewswire/ --

Graphic Security Systems Corporation (GSSC) and 3M have signed a reseller agreement that grants 3M worldwide nonexclusive sales rights to offer GSSC's proprietary Scrambled Indicia technology within the passport and ID markets. The two companies had achieved technical compatibility between 3M travel document readers and the Scrambled Indicia technology some two years ago. That brought enhanced image security to ePassports and travel documents, and gave document authenticators additional verification capabilities.

While current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications, the demands of United States energy needs are spurring new advancements in improving solar cell efficiency.

A team of Northwestern University researchers has developed a new anode coating strategy that significantly enhances the efficiency of solar energy power conversion. Their paper about the work focuses on “engineering” organic material-electrode interfaces in bulk-heterojunction organic solar cells.

Introduction: Bioterrorism is the utilization of microorganisms or toxins in order to produce a disease and/or death in human beings, animals or plants. Different from conventional weaponry, relatively economic means are used that allow the elimination of living beings without destroying the surrounding atmosphere.

The most probably method for spread of bioweapons is aerial transmission, continuing into water supplies and food. The CDC (US Centers for Disease Control and Prevention, Atlanta) has subdivided into three categories the aggressiveness of "Bioweapons".

Category A comprises:

The raging eruption of dust and water from the south pole of Enceladus, Saturn's sixth-largest moon, has intrigued scientists ever since the Cassini spacecraft provided dramatic images of the phenomenon.

Physicist Nikolai Brilliantov from the University of Leicester and colleagues in Germany, have revealed why the dust particles in the plume emerge more slowly than the water vapour escaping from the moon's icy crust.

Enceladus orbits in Saturn's outermost "E" ring. It is one of only three outer solar system bodies that produce active eruptions of dust and water vapour.

Concentric Medical, Inc., the global leader in devices for clot removal in ischemic stroke patients, today announced that results from the use of its Merci Retrieval System(TM) were featured and discussed in seventeen separate presentations at the International Stroke Conference held in New Orleans, Louisiana, February 20-22, 2008. Positive clinical and economic results from the use of the Merci Retrieval System in patients suffering from acute ischemic stroke were discussed during five main podium presentations and more than 12 poster sessions over the three-day conference, which had more than 3,500 people in attendance.

Kava has been used in ceremonies and for recreational and social purposes in the South Pacific since ancient times, much like alcohol, tea or coffee is in other societies today.

In the 1980s other medicinal uses for kava began to emerge and it was marketed in herbal form as a natural way to treat conditions such as anxiety, insomnia, tension and restlessness, particularly in Europe and North America.

More recently, evidence began to emerge about the adverse affect kava could have on the liver and serious concerns about the dangers of kava and the effects on the liver have resulted in regulatory agencies, such as the US Food and Drug Administration and Australia's Therapeutic Goods Administration, banning or restricting the sale of kava and kava products.

A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific Northwest National Laboratory have recorded the first observations of how certain catalyst materials used in emission control devices are constructed.

The PNNL team observed how barium oxide attaches itself to the surface of gamma-alumina. Barium oxide is a compound that absorbs toxic nitrogen oxide, commonly referred to as NOx, from tail-pipe emissions. Gamma alumina is a form of aluminum oxide that is used as a support for catalyst materials, such as barium oxide, that are the active ingredients in exhaust systems.

I am a biomedical engineering laboratory, I am specializing in molecular and cellular biology. Now I'm determinated to open this blog during my Experimental thesis to compare with the scientific community. Not leass important aim is to have suggestions on the design and discussion of experiments on the entire replication of the Human Cytomegalovirus This blog will be a laboratory notebook open to the scientific community. It will be active soon.
