    Description: In a gravity core from the eastern Mediterranean Sea, a chemically and mineralogically distinct, 5.5-cm-thick layer is present above sapropel S-1 and overlain by hemipelagic marls. Calcite is completely absent in this exotic layer, dolomite is present only in small amounts, and the Cr concentrations are significantly enhanced. The layer was deposited primarily under reducing conditions, but the distributions of redox-sensitive elements show that a large part of the exotic layer is now oxidised by a downward-progressing oxidation front. Sediments from within the nearby anoxic, hypersaline Urania Basin are similar to those from the exotic layer, in particular in S-, C-, and O-isotope distributions of pyrite and dolomite, as well as increased Cr concentrations. Mud expulsion due to expansion of gas-rich mud is proposed to explain the presence of the exotic layer outside the Urania Basin. The deposition of an anoxic layer above S-1 shielded the sapropel from oxidation which resulted in the rare occurrence of a complete preservation of S-1 and provides the first minimum age for the start of anoxic mud accumulation in the Urania Basin.

    Notes: [Auszug] 200% ethanol boost from Oz sugar University of Queensland (UQ), Australia, molecular geneticist Robert Birch got more than he bargained for when he introduced a bacterial gene into sugarcane to convert sucrose into its high-value isomer, isomaltulose. In fact, the gene encoding sucrose isomerase, ...

    Notes: [Auszug] Common bacteria, engineered to safely seek out and kill tumors, may well be the next generation of cancer therapeutics. In this issue, Bettegowda et al. report the genome sequence of one such bacterium, Clostridium novyi-NT, which has been engineered to be non-toxic by deleting the major systemic ...

    Notes: [Auszug] This June, Basel-based Novartis Pharmaceuticals made a first reconnoiter into antimicrobial antibodies in its quest to find new weapons to fight infections. It paid $569 million to acquire NeuTec Pharmaceuticals of Manchester, UK, and its two late-stage products, both antibody fragments ...

    Notes: [Auszug] The scarcity of disease in wild plants indicates that the success of plant defense mechanisms in combating pathogen infection rivals that of mammalian immune systems. Although there are some interesting parallels between plant and animal defense strategies—for instance, both groups sacrifice ...

    Notes: [Auszug] The US Food and Drug Administration (FDA) has recently rejected new antibiotics for common infections citing the requirement that the drugs intended to treat non-serious infections prove superior to placebo rather than active controls. With the introduction of more stringent statistical criteria, ...

    Notes: [Auszug] For developers of antibacterial products, this century began very much on the wrong foot. The number of pharmaceutical companies chasing antibiotics continued to drop, few genuinely new antibiotics reached the clinic and investors remained lukewarm toward startups in this sector. But, despite ...

    Notes: [Auszug] A support vector machine (SVM) is a computer algorithm that learns by example to assign labels to objects. For instance, an SVM can learn to recognize fraudulent credit card activity by examining hundreds or thousands of fraudulent and nonfraudulent credit card activity reports. Alternatively, an ...
