A method based on Fast Neutron Resonance Transmission (FNRT) radiography that enables determining weight percentages of oil and water in thick, intact cores taken from subterranean or underwater geological formations. As part of geological exploitation to find oil and water, cores are extracted and tested to determine oil/water content.
This new method allows determining such content rapidly, in non- destructive, specific and quantities analysis of the cores.

Applications


  • Determining the identity and proportions of substances of oil and water content and their distribution in inspected cores

Advantages


  • A non-destructive method which enables to determine the fluid content along the entire length of an intact core or aggregate of cores within their protective sleeves.
  • More comprehensive information and considerable saving of analysis time compared to conventional sampling methods.
    Suitable for all types of rocks including tight-shale rocks.
  • This method enables to measure the weight fraction of oil and water in the core regardless of the core shape, thickness or distribution.
  • The fluid weight fractions in the samples are determined independently, thus the ratio of oil-to-rock weight-ratio is independent of the water content.
  • Due to high penetration of fast neutrons, the method is suitable for screening intact thick rock cores (10-15 cm), for which alternative probes, such as X-rays or slow neutrons suffer limited penetration.

Technology's Essence


In order to map the oil and water content and their distribution, an aggregate of intact cores within their protective sleeves is positioned on a moving conveyor belt and scanned by a broad- energy, fast- neutron beam. The neutrons are detected by a spectroscopic fast neutron imaging detector. The map of neutron-transmission spectra in each pixel provides information of oil/water content and distribution in such cores.

A novel social behavior monitoring system automatically tracks the precise location of each animal at excellent temporal resolution. This innovative technology provides simultaneous identification of complex social and individual behaviors via an integration of RFID and video surveillance.

There is a rapidly growing interest in detecting the molecular substrates of social behavior. This interest is driven by the vast implications of such understanding in both research and the pharmaceutical industry, since some prevalent pathological conditions are mainly characterized by a behavioral deficit or abnormality.

It is extremely challenging to quantify social behavior in a reliable manner. Existing methods struggle to find a balance between objectively quantifying behavior on one hand while enabling a natural, stress-free behavioral estimation on the other hand. Currently, researchers work in a strictly controlled and constrained environment that is estranged and stressful to the animals. The outcome is a highly contaminated measurement of natural behavior. This difficultly becomes increasingly complex when more than one animal is involved as often applied in social behavioral studies.

Applications


  • Rigorous characterization of social organizational deficiencies and evaluation of their severity in animal and human models (for example in autism).
  • An optimized system for estimating the efficacy of clinical treatments.

Advantages


  • Long-term tracking of unlimited number of simultaneously studied animals.
  • Machine based, hence objective and automated quantification of behavior.
  • Excellent spatiotemporal resolution in semi natural environment
  • Flexible- the number, size and distribution of the RFID antennas can be adjusted with different enclosure dimensions.
  • Can be applied from Individual behavioral profile or pairs interactions up to collective social organization of groups.
  • Systematic analysis and classification of basic locomotion up to more complex social

Technology's Essence


Researchers at the Weizmann institute developed a method for tightly controlled monitoring of social behavior in a semi-natural environment. They used integrated and synchronized chip reporting and continuous video postage to precisely locate each individual animal. Using this automated monitoring which provides an exceptional temporal resolution they achieved correct identification of numerous basic individual behaviors as well as complex social behaviors. Such complex behavioral profiles set the basis for subsequent analysis which reveals the formation of a social hierarchy.

Synthetic carbon fixation pathways can allow plants to produce more biomass using the same amount of energy from sunlight. Novel carbon fixation cycles discovered at The Weizmann Institute hold potential to greatly increase the capacity of organisms to convert atmospheric carbon into sugars.

Modern agriculture faces limited arable land and climate changes. Carbon fixation under these conditions will become a significant growth limiting factor. The proposed solution provides the ability to enhance crop yields using the same expanse of land.

The novel technology presents alternative synthetic carbon fixation pathways that were discovered by harnessing a systems biology approach. These pathways are predicted to harbor a significant kinetic advantage over their natural counter parts, making them promising candidates for synthetic biology implementation.

Applications


  • Synthetic organisms utilizing this revolutionary technology can offer higher carbon fixation rates as compared to natural alternatives allowing:
  • Superior rate of biomass generation, providing cost effective feedstock for the production of biofuels.
  • Enhanced food production via increased crop yields.

Advantages


  • Minimal thermodynamic bottlenecks and superior kinetics over natural counterparts.

Technology's Essence


The productivity of carbon fixation cycles is limited by the slow rate and lack of substrate specificity of the carboxylating enzyme, RuBisCo. In his discovery Dr. Milo addresses the inefficiency of the carbon fixation process through an alternative cycle that is predicted to be two to three times faster than the Calvin–Benson cycle, employing the most effective carboxylating enzyme, phosphoenolpyruvate carboxylase, using the core of the naturally evolved C4 cycle.

A computational strategy was applied, comparing kinetics, energetic and topology of all the possible pathways that can be assembled from all ~4,000 metabolic enzymes known in nature.

The results suggest a promising new family of synthetic carbon fixation pathways.

Researchers at the Weizmann Institute developed a novel method to design error-free DNA libraries from error-prone oligonucleotides. The system surpasses existing methods for de novo synthesis of DNA libraries in speed, precision, amenability to automation and ease of combining synthetic with natural DNA fragments. 

All DNA construction protocols struggle with the cumbersome task of cloning and sequencing synthetic DNA fragments, seeking an error-free one. The problem is worsened for longer synthetic DNA which is more prone to errors. Time spent on error correction, clone selection and sequencing is a major bottleneck that prevents de novo DNA synthesis from becoming a routine procedure in labs. 

This innovative solution significantly decreases the need for labor-intensive time-consuming error correction methods, cloning and sequencing. Furthermore, efficient editing and reassembly of different genes is made possible due to a smart recursive reconstruction process.

 

Applications


  • Design and construction of synthetic biological molecules and organisms.
  • Construction of designer DNA libraries.

 


Advantages


  • Applicable in any lab with standard lab equipment. Faster and more precise than existing methods.
  • Amenable to automation, full synthesis in vitro with a modified smPCR protocol.
  • Very simple to combine synthetic and natural DNA fragments.
  • Does not require additional or external methods or reagents for error correction

 


Technology's Essence


Divide and Conquer (D&C), the quintessential recursive problem-solving technique, is applied in silico to divide the target DNA sequence into overlapping oligonucleotides short enough to be synthesized directly, albeit with errors; error-prone oligonucleotides are recursively combined in vitro, forming error-prone DNA molecules; error-free fragments of these molecules are then identified, extracted and used as new, typically longer and more accurate, inputs to another iteration of the recursive construction procedure; the entire process repeats until an error-free target molecule is formed.

257 - Monoclonal antibody to Gliomedin

Description: Monoclonal antibody to Gliomedin (MAb 94) raised against a synthetic peptide corresponding to amino acid residues 273–287 (CVIPNDDTLVGRA), present in the extra cellular region of Rat Gliomedin.

Gliomedin, a glial ligand for neurofascin and NrCAM, is expressed by myelinating Schwann cells and accumulates at the edges of each myelin segment, aligned with the forming nodes of Ranvier. Gliomedin was shown to induce ion channel organization along the nerve axons, elicit formation of myelin and initiate node formation. Immuno-detection of Gliomedin may be used for diagnostics of neurological pathologies or as a marker for nodes of Ranvier in human and various animal model systems.
