En mai 2024, le gouvernement sénégalais tout juste installé suspendait les chantiers de construction dans le pays, le temps de faire des audits pour assainir le secteur. La mesure devait durer deux mois, mais les chantiers n'ont pas repris. Depuis, ce secteur crucial pour le pays – plus de 4% du PIB et plus de 200 000 emplois directs – a plongé dans la crise. Des dizaines de milliers d'emplois sont perdus et la population s'impatiente. De notre correspondante à Dakar,Chaque matin, au rond-point de Keur Massar en banlieue de Dakar, des centaines d'ouvriers attendent, outils à la main, que des camions viennent les chercher pour aller travailler. Mais depuis un an et la suspension des chantiers par les autorités, le travail se fait rare. « Tu viens à 5h du matin, tu vas rester jusqu'à 10h et puis rentrer, se plaint Ida Faye, maçon. Le lendemain, tu reviens encore, tu avais espoir de gagner quelque chose, mais tu rentres encore bredouille. Ça fait des mois que ça dure ! »15 000 emplois formels perdusAu Sénégal, beaucoup de ces jeunes ont voté pour le nouveau président Bassirou Diomaye Faye avec l'espoir du changement, mais leurs conditions de vie se sont détériorées. « Avant, avec l'ancien régime, on pouvait gagner 10 000 ou 11 000 francs CFA par jour, se souvient Rane Dieng, ouvrier du bâtiment. Mais maintenant, on a du mal à gagner ne serait-ce que 5 000. Ça fait un an qu'ils sont là et ils n'ont rien fait pour le pays. Il faut qu'ils arrêtent de faire, d'auditer, de suspendre tout, il faut qu'ils travaillent ».Insa Coly, ferrailleur et père de famille, est en colère et n'arrive plus à penser à son avenir. « Si tu trouves 300 000 francs aujourd'hui, tu prends la pirogue pour rentrer en Espagne. Tu fais l'Espagne trois mois et tu achètes un terrain ici à Dakar. Mais tu travailles ici pendant 20 ans et tu ne peux même pas acheter un terrain. Nos États doivent penser à cette jeunesse-là, sinon nous tous, on va mourir dans la mer ! »Quinze mille emplois ont été perdus dans le secteur formel suite à la suspension des chantiers, selon les syndicats. Certains ouvriers qui avaient des contrats sont au chômage technique. Dans le secteur informel, c'est impossible à chiffrer, mais bien plus élevé selon les représentants de la profession, qui s'impatientent. « Au début, on disait qu'il y avait des audits à faire, qu'il y avait une situation du secteur dont on voulait vraiment avoir une maîtrise, reconnaît Oumar Gueye, du Syndicat national de la construction et du bâtiment, affilié à la Confédération nationale des travailleurs du Sénégal (CNTS). Mais j'avoue que là, on ne comprend plus. »Absence d'accompagnement de l'ÉtatD'autant que l'État sénégalais a accumulé de nombreux impayés auprès des entreprises de construction, pour 300 milliards de francs CFA, soit plus de 450 millions d'euros. « Dans une République normale, même s'il y a des décisions qui doivent être prises, l'idéal serait au moins qu'on puisse nous appeler autour d'une table, juge Oumar Gueye. Si, par exemple, on nous avait payés à l'avance sur la dette intérieure, on aurait au moins pu préparer ces situations-là. Mais du jour au lendemain, on est confronté à cette situation d'arrêt des travaux, on n'a plus de nouveaux marchés, on n'est pas payés, les chantiers qui étaient gagnés ne sont pas exécutés. Donc ça fait mal. »Au dernier trimestre 2024, le chiffre d'affaires du secteur sénégalais de la construction a reculé de près de 10% par rapport à la même période en 2023. Sollicitées, les autorités n'ont pas donné suite à nos demandes d'interview.

Em 2012, o Supremo Tribunal Federal (STF) do Brasil tomou uma decisão histórica ao reconhecer que o aborto de fetos anencéfalos não é crime, atendendo à Arguição de Descumprimento de Preceito Fundamental (ADPF) nº 54 ajuizada pela Confederação Nacional dos Trabalhadores na Saúde (CNTS). A anencefalia é uma condição congênita grave e incompatível com a vida após o nascimento A decisão final do STF representou um avanço significativo nos direitos reprodutivos das pessoas com útero, reconhecendo a autonomia sobre seus próprios corpos.

With almost 60% of all plastic ever produced still polluting our planet, there are enormous issues posed by the massive volume of plastic waste present in our environment. However, by repurposing this massive stockpile of plastic waste into something more valuable we can turn this problem into a solution that benefits us all and paves the way for a brighter, cleaner future In this episode, in discussion with Dr Sam Blaxland,  Dr Alvin Orbaek White, formerly an Associate Professor in Chemical Engineering in the Faculty of Science and Engineering, unveils the incredible power of plastic waste. As one of the world's foremost experts on nanoengineering, Dr. Orbaek White discusses the ground-breaking potential of waste plastic, and how it can be transformed into valuable materials such as hydrogen gas and carbon nanotubes (CNTs). These powerful and versatile materials are the future of innovation, used in everything from cables and batteries to MRI scanners. Dr Alvin Orbaek White is formerly an Associate Professor in Chemical Engineering and former Welsh Government Sêr Cymru II Fellow at Swansea University. He is also an entrepreneur having recently started up his own company TrimTabs to commercialise the sustainable energy knowledge that he has discovered.

Abstract: The diverse electrical, chemical and structural properties of the functional derivatives of carbon nanotubes (CNTs) have shown biomedical possibilities for neuroprosthesis or neural interfaces. However, the studies have been generally confined to metallic CNTs that affect cell viability unless chemically functionalized for biocompatibility. Here, we explored the effects of semiconducting single-walled carbon nanotubes (ssw-CNT), on the active electrical properties of dissociated hippocampal neurons in-vitro using multielectrode array, calcium imaging and whole-cell patch clamp recordings. The findings show that ssw-CNT treatment regulates neural network excitability from burst to tonic firing by changing the calcium dynamics. However, at a single neuronal level, ssw-CNT increases neuronal excitability. Copy rights belong to original authors. Visit the link for more info Podcast created by Paper Player, LLC

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.10.10.511573v1?rss=1 Authors: Zheng, H., Lopez-Ferreras, L., Krieger, J.-P., Fasul, S., Cea Salazar, V., Valderrama Pena, N., Skibicka, K. P., Rinaman, L. Abstract: Objective: The glucagon gene (Gcg) encodes preproglucagon, which is cleaved to form glucagon-like peptide 1 (GLP1) and other mature signaling molecules implicated in metabolic functions. To date there are no transgenic rat models available for precise manipulation of GLP1-expressing cells in the brain and periphery. Methods: To visualize and manipulate Gcg-expressing cells in rats, CRISPR/Cas9 was used to express iCre under control of the Gcg promoter. Gcg-Cre rats were bred with tdTomato reporter rats to tag Gcg-expressing cells. Cre-dependent AAVs and RNAscope in situ hybridization were used to evaluate the specificity of iCre expression by GLP1 neurons in the caudal nucleus of the solitary tract (cNTS) and intermediate reticular nucleus (IRt), and by intestinal and pancreatic secretory cells. Food intake was assessed in heterozygous (Het) Gcg-Cre rats after chemogenetic stimulation of cNTS GLP1 neurons expressing an excitatory DREADD. Results: While genotype has minimal effect on body weight or composition in chow-fed Gcg-Cre rats, homozygous (Homo) rats have lower plasma glucose levels. In neonatal and adult Gcg-Cre/tdTom rats, reporter-labeled cells are present in the cNTS and IRt, and in additional brain regions (e.g., basolateral amygdala, piriform cortex) that lack detectable Gcg mRNA in adults but display transient developmental or persistently low Gcg expression. Compared to wildtype (WT) rats, hindbrain Gcg mRNA and GLP1 protein in brain and plasma are markedly reduced in Homo Gcg-Cre rats. Chemogenetic stimulation of cNTS GLP1 neurons reduced overnight chow intake in males but not females, the effect in males was blocked by antagonism of central GLP1 receptors, and hypophagia was enhanced when combined with a subthreshold dose of cholecystokinin-8 to stimulate gastrointestinal vagal afferents. Conclusions: Gcg-Cre rats are a novel and valuable experimental tool for analyzing the development, anatomy, and function of Gcg-expressing cells in the brain and periphery. In addition, Homo Gcg-Cre rats are a unique model for assessing the role of Gcg-encoded proteins in glucose homeostasis and energy metabolism. Copy rights belong to original authors.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.09.29.510103v1?rss=1 Authors: Onwukwe, C., Ji, Y., Smith, J., Laub, H., Posa, L., Keller, A., Masri, R., Cramer, N. Abstract: The parabrachial complex (PB) is critically involved in aversive processes, including pain. We have reported that chronic pain is associated with amplified activity of PB neurons in rodent models of neuropathic pain. Here we demonstrate that catecholaminergic input from the caudal nucleus of the solitary tract (cNTScat)--a stress responsive region that integrates intero- and exteroceptive signals- causes amplification of PB activity and their sensory afferents. Using a virally mediated expression of a norepinephrine (NE) sensor, NE2h, and fiber photometry in anesthetized mice, noxious mechanical and thermal stimuli caused prolonged NE transients in PB that far outlast the noxious stimulus. Similar NE transients in PB were evoked by focal stimulation of the superficial cNTS, a region that contains the noradrenergic A2 cell group that projects densely upon PB. In vitro, optical stimulation of cNTScat terminals depolarized PB neurons and increased their frequency of spontaneous excitatory synaptic inputs. A dual opsin approach showed that sensory afferents from the caudal spinal trigeminal nucleus (SpVc) are potentiated by cNTScat terminal activation. This potentiation was coupled with a decrease in the paired pulse ratio, consistent with an cNTScat mediated increase in the probability of release at SpVc synapses. Together, these data suggest that A2 neurons of the cNTS generate long lasting NE transients in PB which increase excitability and potentiate responses of PB neurons to sensory inputs. These reveal a mechanism through which stressors from multiple modalities may potentiate the aversiveness of nociceptive stimuli. Copy rights belong to original authors.

Cada 14 de junio se conmemora el Día Mundial del Donante de Sangre, y este año tocó a México ser anfitrión de las actividades que se realizaron para concienciar a todo el mundo sobre la necesidad de disponer de sangre y productos sanguíneos seguros para transfusiones, así como la crucial contribución que efectúan los donantes de sangre voluntarios y no remunerados a los sistemas nacionales de salud. El tema de la campaña este año es “Donar sangre es un acto de solidaridad. Súmate al esfuerzo y salva vidas”, que tuvo como propósito destacar la importancia de la contribución esencial de los donantes de sangre para salvar vidas y fortalecer la solidaridad en las comunidades. Al respecto, el Dr. Jorge Trejo Gómora, Director general del Centro Nacional de la Transfusión Sanguínea, CNTS, señaló que en el 2020 se logró una gran participación de personas que actuaron de manera altruista donando sangre y plasma para pacientes que requerían transfusiones. Aun con las restricciones por la movilidad y las medidas sanitarias en los centros de salud, la respuesta fue superior a la esperada y de allí que se haya registrado un importante incremento en la donación voluntaria.

Cette semaine dans le magazine santé, on se penche sur la question du don de sang et son importance et on en parle avec Yao Séna Tété, responsable de l'équipe mobile du CNTS, le Centre national de transfusion sanguine au Togo.

Omar Fabian: It's summer and film director James Cameron has just dropped another scorching hit. In Terminator 2: Judgment Day, we find mother-son duo Sarah and John Connor running for their lives, and for the lives of all humankind, with the help of a bad cyborg turned good played by none other than Arnold Schwarzenegger. There are so many undoubtedly cool visual features to take away from this iconic film. Little known fact: it actually won four Academy awards for its sound and visual effects. But if you ask around, more than likely, you'll find that the coolest has to be the T-1000: the liquid-metal robot sent from the future to destroy John Connor and ensure victory for our machine overlords.   Alireza Dolatshahi-Pirouz:  You have this robot that, it's not electronic but it's still a robot and it's because somehow that material that made it is self-healing and it's animated in some ways that we couldn't understand back then.[OF]:  That's Alireza Dolatshahi-Pirouz, a professor in the Department of Micro- and Nanotechnology at the Technical University of Denmark. You might remember him from a previous episode of our podcast, where he described how his group is developing stretchy, eco-friendly electronics they describe as “fleco”—[ADP]:   “So flexible and eco, fleco”.[OF]:  Now, they're back with a new material that stretches, conducts electricity, and perhaps most astoundingly, heals itself—not unlike the T-1000 from Terminator 2, which Dolatshahi-Pirouz admits was the inspiration for his lab-work.  The team calls their new wonder material CareGum. 

Markus Buehler of the Massachusetts Institute of Technology (MIT) and editor of the Impact section of MRS Bulletin interviews Desirée Plata, the Gilbert W. Winslow Career Development Associate Professor of Civil and Environmental Engineering at MIT about her group's development of new methods toward functionalization of carbon nanotubes with heteroatoms, which enables covalent attachment, opening up a world of potential materials structures. This research is relevant because common functionalization techniques for carbon nanotube materials (and other, similar nanostructures) are often hazardous, and have adverse environmental impacts, and lack precision. The research group evaluated an in situ functionalization technique utilizing oxygen-containing alkyne precursors, which offers a novel, more sustainable pathway for bottom-up engineering. Through a detailed assessment of the mechanisms by which nanotubes form, the researchers were able to direct new pathways toward bottom-up design of materials while considering sustainability, and especially environmental health, as a parameter during optimization and design. Their work is published in MRS Bulletin (https://doi.org/10.1557/s43577-020-00019-7)

Global Positioning System, or GPS is perhaps the best known of the satellite navigation systems, helping us find our way every day. Back in the 1970's Bradford Parkinson and Hugo Fruehauf were two of the inventors who miniaturised atomic clocks and launched them in Earth orbit satellites. This was part of the US Department of Defense's plan to track ships and aircraft and guide targeted missiles. In the intervening years, Brad and Hugo had no idea just how far the civilian applications of GPS would go. Alongside Richard Schwartz and James Spilker, they have just been awarded the prestigious the Queen Elizabeth Prize for Engineering. The age of silicon chip based computing could be coming to an end. Difficulties in shrinking silicon transistors, or switches, into ever smaller processors led researchers at MIT to search for alternative semiconducting materials to replace them. Cue carbon nanotubes, tubes of carbon atoms many tens of thousands of times narrower than a human hair. Electrical engineer Max Shulaker and his team have overcome spaghetti-like tangles of CNTs and varying levels of conductivity to create a 16bit processor. He says that rather than a straight forward replacement to silicon, the initial hope is that CNT chip technology can be added to existing silicon wafers. Steven Strogatz and Monty Lyman have been shortlisted for the Royal Society Insight Investment Science Book Prize this year. In "Infinite Powers", Professor of applied maths at Cornell University, Steven Strogatz tells Adam Rutherford the story of calculus and why his book has a warning saying "this book is dangerous, it will make you love mathematics!" And in "The Remarkable Life of the Skin" Dr. Monty Lyman takes Claudia Hammond on an intimate journey across our surface. They discuss advances in skin treatments, new research on the importance of our diet and our skin and the vital role our largest organ plays in our lives.

A variety of electronic and optoelectronic devices based on carbon nanotubes (CNTs) has been implemented during the last two decades. For their optoelectronic characterization, diffraction-limited techniques such as photocurrent (PC) and electroluminescence (EL) microscopy were employed. However, for the full characterization of these nano-devices, novel techniques providing nanoscale spatial resolution are desired. This work presents antenna-enhanced optoelectronic probing as a new scanning probe technique for the investigation of nanoelectronic devices. Based on tip-enhanced near-field optical microscopy, sub-diffraction spatial resolution is achieved by employing an optical antenna for the focusing of light. It is applied to study PC and EL signals with a spatial resolution better than 40 nm for the first time. Complemented with antenna-enhanced Raman and topography images, new insights into the optoelectronic properties of CNT based devices are gained. In the first part of this thesis, an antenna-enhanced photocurrent microscopy study is demonstrated. The signal enhancement mechanism of PC signals is investigated and compared with expectations based on theory. While in spectroscopic applications both the excitation AND the emission rate is enhanced, in optoelectronic applications either the excitation OR the emission rate is affected by the antenna. Theory predicts therefore a weaker total signal enhancement and a lower spatial resolution of optoelectronic signals compared to Raman scattering by a factor of √2, which is experimentally confirmed. Then, two applications are presented. First, CNT-metal interfaces are studied and an exponential decay of the band bending at the contacts with a decay length of about 500 nm is revealed. Second, sub-diffraction potential modulations along the CNT channel of another device are probed that remain undetected using confocal microscopy. Combined with high-resolution spectroscopic images of the Raman signal, defects can be excluded as the cause for these modulations. Correlating the PC with the topographic profile reveals charges associated with a particle on the sample substrate as the possible origin. In the second part, antenna-enhanced electroluminescence microscopy is introduced. The EL emitted by a heterogeneous CNT network is studied with a resolution better than 40 nm. For the first time, pinning of the EL emission to a point-like region of smaller than 20 nm is observed. This strong localization occurs at a junction of at least one metallic and one semiconducting CNT. By probing the PC signal at this junction, the presence of a strong local electric field is revealed, probably caused by a Schottky contact. This allows to identify impact excitation as the most likely origin of the EL emission. A second device, based on a single CNT, was investigated and, in contrast to the network device, the size of the EL source is extended over a length of more than 100 nm.

Semiconducting single-walled carbon nanotubes (CNTs) exhibit a chirality depended band structure of a one-dimensional lattice. Due to the radiative recombination of excitons CNTs emit photoluminescence in the near and mid infrared ranges depending on the tube diameter. Excitons are subject to diffusion along the tube before radiative recombination. Thereby they probe sites that give rise to spin-flips or non-radiative decay, or, at cryogenic temperatures, they localize in zero-dimensional quantum dots at the minima of the local energy potential landscape. Thus, the optical spectroscopy of individual CNTs probes not only the intrinsic exciton dynamics, like diffusion and intrinsic life-time, but also disorder of the CNT lattice and its environment. Intrinsic and extrinsic inhomogeneities and impurities may give rise to photoluminescence quenching, brightening of dark exciton states or generation of charged exciton complexes. In the framework of this thesis the physics of excitons in CNTs was investigated in two ways: On the one hand their environment was varied with an static electric field, on the other hand the CNTs were isolated from their environment. A comprehensive set of optical spectroscopy techniques was used to study individual CNTs at low temperatures. This included photoluminescence excitation, (time-resolved) photoluminescence, and photon correlation spectroscopy. This work identified exciton localization as predominant feature of individual CNTs at cryogenic temperatures. CNTs on substrate exhibited asymmetric line shapes at low temperature and temperature dependent shifts on the PL energy. Moreover for constant temperature, PL energies were subject to spectral diffusion, which arose - in analogy to compound semiconductor quantum dots - from interaction with a few close charge fluctuators in the dielectric environment. In addition, evidence for exciton localization was provided by the non-classical photon emission statistics of cryogenic CNTs. The main focus of this thesis was the study of individual CNTs in a static electric field. A metal-oxide-semiconductor device was used to probe for the transverse polarizability of excitons. In consequence, the PL energy of CNTs exhibited red-shifts as a quadratic function of the perpendicular electric field. However, a subclass of CNTs was characterized by satellite peaks in the emission profile. By their energy splitting they were assigned to PL emission from dark exciton states, e.g. triplet and k-momentum excitons, and resulted presumably from impurity induced symmetry breaking. As a function of the electric field, CNTs with a broken symmetry featured linear shifts of the PL energy of bright and triplet excitons. A third energy scale in the exciton fine structure was manifested by CNTs that exhibited the emergence of a satellite peak as a function of the electric field. These satellites were assigned to the PL of trions generated by doping of individual CNTs with charges from close oxide states. Presumably such close charge states played also an important role in the variation of the excitation spectra of individual CNTs, which was observed as a function of the applied electric field. This variation could be mediated by switching of charge states, which varied the localization potential of excitons. Finally, the extrinsic effects of the surrounding dielectric medium were contrasted by the remarkable optical properties of as-grown suspended CNTs. Freely suspended CNTs featured isolated localized excitons with narrow linewidths, intrinsic exciton lifetime and a significantly increased quantum yield. Moreover, they lack signatures of spectral diffusion or intermittency even on the shortest timescales.
