LONG LIFETIME ALPHA-HEMOLYSIN NANOPORES
Described herein are variants of alpha-hemolysin having at least one amino acid substitution at H35G, E111N, M113A, and/or K147N in the mature, wild-type alpha-hemolysin amino acid sequence. In certain examples, the variant may have a substitution at E111S, M113S, T145S, K147S, or L135I in the mature alpha-hemolysin amino acid sequence. The α-hemolysin variants may also include a substitution at H144A and/or a series of glycine residues spanning residues 127 to 131 of the mature, wild-type alpha hemolysin. Also provided are nanopore assemblies including the alpha-hemolysin variants, the assembly having an increased nanopore lifetime. Further, provided are variants that, in addition to providing increased lifetime, provide a decreased time-to-thread. Hence, the variants provided herein both increase nanopore lifetime and improve efficiency and accuracy of DNA sequencing reactions using nanopores comprising the variants.

MESENCHYMAL-LIKE STEM CELLS DERIVED FROM HUMAN EMBRYONIC STEM CELLS, METHODS AND USES THEREOF
The present invention relates to methods of generating and expanding hitman embryonic stem cell derived mesenchymal-like stem/stromal cells. These hES-MSCs are characterized at least in part by the low level of expression of IL-6. These cells are useful for the prevention and treatment of T cell related autoimmune disease, especially multiple sclerosis, as well as for delivering agents across the blood-brain barrier and the blood-spinal cord barrier. Also provided is a method of selecting clinical grade hES-MSC and a method of modifying MSC to produced a MSC with specific biomarker profile. The modified MSC are useful for treatment of various diseases.

GENETICALLY MODIFIED MICROORGANISMS HAVING IMPROVED TOLERANCE TOWARDS L-SERINE
The present invention generally relates to the microbiological industry, and specifically to the production of L-serine or L-serine derivatives using genetically modified bacteria. The present invention provides genetically modified microorganisms, such as bacteria, wherein the expression of genes encoding for enzymes involved in the degradation of L-serine is attenuated, such as by inactivation, which makes them particularly suitable for the production of L-serine at higher yield. The present invention also provides means by which the microorganism, and more particularly a bacterium, can be made tolerant towards higher concentrations of serine. The present invention also provides methods for the production of L-serine or L-serine derivative using such genetically modified microorganisms.
Brassica plant comprising a mutant indehiscent allele
This invention relates to crop plants of which the fruit dehiscence properties are modulated. More specifically the invention relates to improved methods and means for reducing seed shattering, or delaying seed shattering until after harvest, while maintaining at the same time an agronomically relevant treshability of the pods, and for increasing yield.
