Leeward PNP Rally criticized on Social Media

first_imgFacebook Twitter Google+LinkedInPinterestWhatsApp Facebook Twitter Google+LinkedInPinterestWhatsAppProvidenciales, TCI, November 22, 2016 – The Leeward and Long Bay rally for the PNP on Saturday night had strong turn out, but there were questions about some of the happenings at the event staged at Heaven Down Rock; among them, the performance of the Long Bay High School Choir.Social media was buzzing with perspectives on whether this was right or wrong and there were reports that the matter would be reported as out of order and lacking integrity.  The member for the Constituency happens to be the Minister of Education, and the choir is from a government school.We reached out to Deputy Premier, Akierra Missick to seek clarity or comment, she said she had no comment to make except to say that she upholds the laws of the country.

Deschamps denies Laportes France snub is personal

first_imgFrance coach Didier Deschamps insists he cannot have two left-footed defenders at centre-back in his team following Aymeric Laporte’s shocking claimsSince arriving from Athletic Bilbao in last January for a club record fee of £57m at Manchester City, Laporte has become regarded as one of the best defenders in Europe.But the 24-year-old surprisingly continues to be overlooked by Deschamps for France with the likes of Kurt Zouma and Mamadou Sakho getting the nod instead.This led the uncapped Laporte to make a stunning accusation against Deschamps by claiming it’s personal last week.But the former Juventus boss insists his decision was based purely on footballing reasons.Premier LeaguePremier League Betting: Match-day 5 Stuart Heath – September 14, 2019 Going into the Premier League’s match-day five with a gap already beginning to form at the top of the league. We will take a…“I do not understand [why Laporte made those statements]. I do not know,” Deschamps told RMC Sport.“I do not have a problem with anyone. When I choose someone it is not for me. I repeat. I only have one thing to say to him and that is that he continues to perform well.“If you tell me he must be in [Marseille centre-back Adil] Rami’s place then I stop you right away.“Sorry but two left-footed defenders at centre-back at international level… We have a lot of left-footers and few right-footers.”Laporte, who’s played every single one of City’s Premier League games this season, will likely start in today’s clash against Crystal Palace.last_img read more

Communication channel between cells and machines paves way toward biohybrid robots

Biomim. 7 (2012) 046017 (7pp). DOI: 10.1088/1748-3182/7/4/046017 Copyright 2012 Phys.org All rights reserved.

Several proteins naturally produce nitric oxide in response to a chemical stimulus, but the researchers wanted to produce nitric oxide in larger amounts and in response to an optical stimulus. To achieve this, the researchers explained how they were able to “hijack” the protein’s electron transfer pathway by severing a particular gene coding for a binding site required by the native pathway. In addition to removing that binding site, the researchers inserted amino acid structures called light-oxygen-voltage (LOV) domains into one or two regions in the protein. Since these structures are capable of accepting an electron from an incoming photon, they make the protein produce nitric oxide in response to light.In experiments, the researchers observed that mutant cells that were modified with LOV domains produced more nitric oxide than the wildtype cells when exposed to light. Increasing the light stimulus further increased the mutant cells’ nitric oxide production, while the wildtype cells exhibited limited photosensitivity. The researchers also found that mutant cells with two LOV domains produced about twice as much nitric oxide as those with only one LOV domain. When coupled to an electrode, the mutant cells could produce sufficient nitric oxide to cause a change in the electrode’s current. By changing the light intensity, the researchers could control the communication signals traveling through this optical-chemical-electrical cascade. Unlike typical solid-state photodetectors, these devices have the ability to self-reproduce and the potential to combine input signals to perform computation. These advantages could be turned into useful applications in a future generation of advanced robots. “This work is part of a bigger project to build a swimming bio-hybrid robot called ‘Cyberplasm,'” Frankel said. “These cells are the ‘eyes’ of the robot able to respond to light and tell the robot to alter its swimming pattern in response. The complete robot is still in development, but we are working on the individual parts. Potential applications are robots that can swim into contaminated areas, detect chemicals and report back.”Co-investigators of the Cyberplasm project are Joseph Ayers at Northeastern University in Boston, Chris Voigt at MIT, and Vlad Parpura at the University of Alabama.The next step for the researchers is to produce cells that can communicate with electronics in response to chemical stimuli, and in addition communicate with each other. One of the major challenges in developing bio-hybrid robots consists of creating an interface to allow communication between the biological and electronic components. This task is inherently difficult because the vast majority of cellular signals are simply not compatible with electronics. Most cellular processes use signals that travel too slowly to interface with electrical signals, and exposure to electrical charges has negative effects on many cells, which can lead to cell death. Despite these challenges, a team of researchers, Orr Yarkoni, Lynn Donlon, and Daniel Frankel from the Department of Chemical Engineering at Newcastle University in the UK, has developed a way to make communication between these two domains possible. In their study, the researchers genetically engineered protein cells from a Chinese hamster ovary to produce nitric oxide in response to visible light. When the mutant cells were coupled to a platinum electrode, the resulting device could convert an incoming optical signal to a chemical signal, which could then be converted into an electrical signal. This signal transduction pathway provides an important step in developing future bio-hybrid robots.”The bio-electronic interface is notoriously difficult to manipulate,” Frankel told Phys.org. “Usually the electronics are modified to fit the biological system of interest with limited success. This is the first time that we have tried an alternative approach, to modify the biology (via genetic engineering) to fit the electronics.”One of the keys to opening a communication channel was identifying nitric oxide as a suitable chemical compound for the middle signal in the pathway. As the researchers explained, nitric oxide is one of the few compounds that meets all the requirements for this role: it can permeate cells, is highly diffusible, has a relatively short half-life, and is one of the rare cell signaling molecules that remains in its gaseous form in any cell environment. As an indication of its aptitude for signaling, nitric oxide is widely used in nature, playing a role in areas such as muscle relaxation, blood vessel widening (vasodilation), inadequate blood flow (ischaemia), penile erection, and stroke. center_img Illustration of the experimental setup used to investigate the production of nitric oxide by genetically modified protein cells in response to light.

Currently, researchers are working on integrating living cells and other biological components with electronic components in an attempt to create bio-hybrid robots. These robots could act autonomously, imitate some animal behaviors, and have the ability to self-replicate some of their parts. This document is subject to copyright.
