Ground force: lawnmowing robots

Ground force: lawnmowing robots | Complex Insight  - Understanding our world | Scoop.it

21 years ago I started work in a small robotics company in the North of England. They built experimental autonomous and semi autonomous robot platforms for researchers and industry. I saw my first concept robot vaccum cleaner 20 years ago. I remember well the discussions one of the engineers about the challenges of building everyday robots in terms of functionality,  compute requirements, safety and cost. The time line from concept research to mainstream manufacturing is always a sobering one as is understanding market requirments to drive product adoption and growth. I was reminded of all these when reading a BBC article on lawnmowing robots entering into the market. If you are interested in robotics (or have a large garden) worth a read.

Quantitative Temporal Viromics: An Approach to Investigate Host-Pathogen Interaction: Cell

Quantitative Temporal Viromics: An Approach to Investigate Host-Pathogen Interaction: Cell | Complex Insight  - Understanding our world | Scoop.it

A systematic quantitative analysis of temporal changes in host and viral proteins throughout the course of a productive infection could provide dynamic insights into virus-host interaction. We developed a proteomic technique called “quantitative temporal viromics” (QTV), which employs multiplexed tandem-mass-tag-based mass spectrometry. Human cytomegalovirus (HCMV) is not only an important pathogen but a paradigm of viral immune evasion. QTV detailed how HCMV orchestrates the expression of >8,000 cellular proteins, including 1,200 cell-surface proteins to manipulate signaling pathways and counterintrinsic, innate, and adaptive immune defenses. QTV predicted natural killer and T cell ligands, as well as 29 viral proteins present at the cell surface, potential therapeutic targets. Temporal profiles of >80% of HCMV canonical genes and 14 noncanonical HCMV open reading frames were defined. QTV is a powerful method that can yield important insights into viral infection and is applicable to any virus with a robust in vitro model.

Eli Levine's curator insight, April 30, 5:41 PM

It seems that we are about to get closer to death, as our antibiotics, pesticides, herbicides and all other methods of cheating death, disease and crop failure fail.

 

This is before we get into conversations about the looming international and intranational conflicts that are simmering beneath the surface.  At least these can be dealt with with sensible policy changes and changes in attitude, perspective and disposition, if not out right content in our leadership cadres.

 

But alas, I don't see that happening in the foreseeable future.

 

Time is ticking away.

 

And we too will go through an indiscriminate die off phase where friends and family will die off, along with enemies and pestilential people as well.

 

I'd like to think that we'd come off better than before.

 

But, that's the thing about these indiscriminate methods of killing large swaths of the population.  It very rarely yields anything other than what was already present.

 

At least wages should be better, due to the new shortage of laborers (assuming that robots haven't taken over our labor force in the meantime).

 

I'd like to think that our lot is constantly improving, even during these negative phases.

 

But, I know that it's not going to be easy, especially for most of our Western and American population who don't have experience handling these kinds of things.

 

Ah well.

 

Think about it.

Polar Swarms

Polar Swarms | Complex Insight  - Understanding our world | Scoop.it
A new theory can explain the formation of swarming patterns observed in ensembles of self-propelled polar particles.

Via Eugene Ch'ng

Eugene Ch'ng's curator insight, April 13, 5:27 AM

How do individual animals form swarms, schools, and flocks? In the 1990s, physicists modeled collections of self-propelled particles (so-called “active matter”) and could simulate the ordering that occurs in animal flocks.  Theoretical models have reproduced many aspects of this collective behavior, but a number of questions have persisted. One concerns the observation that in polar, active matter—think of a collection of small, mutually interacting swimming arrows—the particles organize themselves into three possible pattern classes: density waves, solitary waves (solitons), and traveling “droplets.”

No single theory has been able to explain the formation and diversity of these patterns. However, in a paper in Physical Review Letters, Jean-Baptiste Caussin and collaborators from institutes in France, Germany, and the Netherlands, have solved a hydrodynamic model of polar active particles and have accounted for the origin and variety of these propagating swarm structures...

The race to contain West Africa's Ebola outbreak (Wired UK)

The race to contain West Africa's Ebola outbreak (Wired UK) | Complex Insight  - Understanding our world | Scoop.it
Digital volunteers are racing to map regions in West Africa where the Ebola virus, which has a 90 percent fatality rate, continues to spread
ComplexInsight's insight:

The use of OpenStreetMap (OSM) as an unifying geodata system is increasing in humanitarian aid. The current Ebola outbreak in West Africa is a challenge at multiple levels for teams trying to coordinate a response. Due to years of war there are few up to date maps in the region and multiple boundaries mean different groups are collecting data. Digital volunteers creating new OSM entries will be a key asset in enabling health officials to manage the outbreak and hopefully bring things under control.

The world’s most endangered food

The world’s most endangered food | Complex Insight  - Understanding our world | Scoop.it
Many varieties of fruit, meat and vegetable are disappearing from our plates, says Rachel Nuwer. Why is this happening, and can we stop the rot?
ComplexInsight's insight:

 Its probably not often we stop to think of the impacts of agriculture on the evolution of foodstuffs and what varieties of plants are being lost, along with their distinct tastes, benefits and properties. Compared to pre 1900 agriculture an estimated 75% of global farmed plant diversity is now gone and lost. Diversity is key to sustainable agriculture over the long term, so the points made in the article are particularly worrying. Thought provoking article from the BBC / worth reading.

Three Impediments to the Internet of Things | VentureFizz | Complex Insight  - Understanding our world | Scoop.it
Three Impediments to the Internet of Things - blog post by Walter Dick of Ascent Venture Partners
ComplexInsight's insight:

 Walter Dick believes the major impediments  for IoT are:

 

1. Networks are not up to Par..

2. Security needs to improve

3. Batteries need innovating

 

Not sure I agree 100% on his top 3 but they are certainly contributing factors. Companies like Blackberry and Nokia Oyj (the parent company of the phone manufacturer recently purchased by Microsoft) are incredibly well placed to deliver IoT in terms of network and security and have expertise for power management. Unfortunately  Blackberry is not focused on IoT much at all and is beset with its own problems. I am more hopeful on Nokia Oyj / now they have hived off the phone business they retained the networking infrastructure and mapping divisions along with the expertise in power electronics. It would be interesting to see them pioneer in the IoT area as they once did with mobile phones...

Cellular traffic control system mapped for the first time

Cellular traffic control system mapped for the first time | Complex Insight  - Understanding our world | Scoop.it

Cells regulate the uptake of nutrients and messenger cargos and their transport within the cell. This process is known as endocytosis and membrane traffic. Different cargos dock onto substrate specific receptors on the cell membrane. Special proteins such as kinases, GTPases and coats, activate specific entry routes and trigger the uptake of the receptors into the cell. For their uptake, the receptors and docked cargos become enclosed by the cell membrane. In the next steps, the membrane invaginates and becomes constricted. The resulting vesicle is guided via several distinct stations, cellular organelles, to its final destination in the cell.

 

For her study, Dr. Prisca Liberali, senior scientist in the team of Professor Lucas Pelkmans, sequentially switched off 1200 human genes. Using automated high-throughput light microscopy and computer vision, she could monitor and compare 13 distinct transport paths involving distinct receptors and cellular organelles. Precise quantifications of thousands of single cells identified the genes required for the different transport routes. Surprisingly, sets of transport routes are co-regulated and coordinated in specific ways by different programs of regulatory control.

 

Subsequently, Dr. Liberali calculated the hierarchical order within the genetic network and thereby identified the regulatory topology of cellular transport. "The transport into the cell and within the cells proceeds analogously to the cargo transport within a city" describes the scientist. "Like in a city, the traffic on the routes within a cell and their intersections is tightly regulated by traffic lights and signs to guide the cargo flow."

 

Thanks to this unique quantitative map, the fine regulatory details of transport paths and processes within a cells could be mapped for the first time. Particularly the genes that encode for these traffic lights and switches are often de-regulated in disease. With this map, it is now possible to predict how this leads to traffic jams in the cells, causing the disease phenotype. Alternatively, since many drugs have been developed to target these traffic lights and switches, the map can be used to come up with possible drug combinations to target unwanted traffic, such as viruses, to the waste disposal system of the cell.

Mapping the fine regulatory details of transport paths and processes within cells is key to understanding gene and protein functions, cancer, viral interactions and potential treatments.  Interesting read.

FANTOM

FANTOM | Complex Insight  - Understanding our world | Scoop.it
ComplexInsight's insight:

In our bodies every cell contains the same genetic code, however the active or expressed genes determine cell function.  Which genes are expressed is controlled by tiny bits of the genome called promoters and enhancers and different cell types are determined by different combinations of promoters and enhancers. Now an international consortium of researchers known as FANTOM, led by the RIKEN institute in Japan have created the  clearest map yet of how genes control cells to make our bodies function. The map is already challenging ideas about what our genes do and how they interact and may accelerate the development of gene-based therapies. The team examined more than 800 human tissue samples, covering nearly all cell types, and  found 44,000 enhancers and 180,000 promoters that control gene expression.

Towards a Methodology for Validation of Centrality Measures in Complex Networks

Towards a Methodology for Validation of Centrality Measures in Complex Networks | Complex Insight  - Understanding our world | Scoop.it

Our empirical analysis demonstrates that in the chosen network data sets, nodes which had a high Closeness Centrality also had a high Eccentricity Centrality. Likewise high Degree Centrality also correlated closely with a high Eigenvector Centrality. Whereas Betweenness Centrality varied according to network topology and did not demonstrate any noticeable pattern. In terms of identification of key nodes, we discovered that as compared with other centrality measures, Eigenvector and Eccentricity Centralities were better able to identify important nodes.

ComplexInsight's insight:

Our adaptive immune system, the one that responds to specific pathogens, relies on T cells and B cells. These cells make proteins that have a key job: distinguish between the harmless proteins in all of our cells and foreign proteins that may be harmful. In T cells, these molecules are creatively called T cell receptors (TCRs), and in B cells they are antibodies.
