It seems likely that C60+ will act as a stable site for a wide variety of adducts and that these entities will contribute to the Diffuse Interstellar Bands.  John Maier's group in Basel is looking for species like C60(Fe)+.

Ian McKellen speaks at FSU about his acting career and some of the fascinating things that he has learned through theater and personal experience.

Come share with me the memories of where ideas have come from during my life - from childhood to old age. You may find it helpful in encouraging your own brains to come up with new ideas. They won't all be useful - as I have found in this case of min....

Before the 1970s, well fixed specimens of gastric mucosa were rare. Then the flexible endoscope was introduced. This enabled gastroenterologists to take numerous well-fixed small biopsies from the stomach. Gastric histology and pathology were clearly....

Telomeres protect chromosome ends and help stabilize the genome. Throughout human life and in aging, telomeres often erode down, eventually causing cells to malfunction or die. The highly regulated cellular enzyme telomerase adds telomeric DNA to tel....

Immune surveillance by virus-specific CD8+ cytotoxic T lymphocytes (CTLs), or killer T cells, has long been known to be central to the control of acute infections and some cancers, though the role of CTL memory in the rapid recall of immune protectio....

In 2010, we chemically synthesized the 1078 Kb Mycoplasma mycoides genome and transplanted it into a recipient cell cytoplasm to create a 'synthetic cell', JCVI-syn1.0 (Science, 329, 52-56, 2010). We identified several hundred non-essential genes by ....

Nitric oxide research has grown rapidly with about 150,000 research publications describing its biological effects. It is an important messenger molecule that affects most tissues and biological processes. Many effects of nitric oxide are mediated by....

The concept of bioelectricity emerged in the late 18th century, based on the experiments of Galvani and Volta. Sixty years ago, Hodgkin and Huxley showed that the nerve impulse is a result of permeability changes of the nerve membrane. This raised th....

The complexity of modern biological life has long made it difficult to understand how life could emerge spontaneously from the chemistry of the early earth. We are attempting to synthesize simple artificial cells in order to discover plausible pathwa....

Reversible protein phosphorylation can be considered one of the most prevalent mechanism by which eukaryotic cellular events are regulated. It is directly involved in numerous pathological conditions, and bacterial and viral diseases. This process wa....

Conservation laws are very important in quantum physics. Two examples of applications will be given. First, optical pumping which uses transfer of angular momentum from polarized photons to atoms to produce highly polarized atomic gases. Then, laser ....

When Monsanto first tried to introduce GMO seeds into Europe there was a backlash by the Green parties and their political allies, who feared that American agro-business was about to take over their food supply. Thus began a massive campaign not agai....

Beginning with an exception to normal function caused by a genetic aberration, one may hope to find at least one protein with non-redundant function in a certain biological process. This approach permitted the identification of the receptor for bacte....
