Artificial muscle can heal itself

first_imgMaterials scientists would kill to be able to produce a material as amazing as biological muscle, which can retract on command, stretch by about 70% without damage, and heal its own nicks and tears. Now, researchers say they’re getting closer with a synthetic material that can do all these things, though not as well as natural muscle. The advance could one day be useful in robotics and prosthetics.The concept of an artificial muscle dates back decades. Researchers have proposed numerous different starting materials, from atom-thick tubes of carbon called nanotubes to ceramics to metal alloys. In 2000, scientists showed that some rubberlike polymers called elastomers could be reversibly stretched to up to three times their length by applying a voltage across them. Like almost all synthetic materials, however, these elastomers needed someone to fix them if they were damaged. Working separately, other scientists have used elastomers as the basis for self-healing polymers—materials that can repair tears, seal holes, and even join cut edges. However, most of these have been quite weak and lacked elasticity, making them poor artificial muscles. And nobody has produced an artificial muscle that can repair itself.Until now, that is. Materials chemist Zhenan Bao of Stanford University in Palo Alto, California, and colleagues unveil today in Nature Chemistry a group of elastomers called Fe-Hpdca-PDMS. The material comprises long, randomly entangled polymer chains containing silicon, oxygen, nitrogen, and carbon atoms mixed with an iron salt. The iron forms chemical bonds with the oxygen and the nitrogen atoms in the polymer, joining the polymer chains both to themselves and to each other, like strings joined with elastic bands at the crossing points. These crosslinks do not prevent the polymer chains from moving altogether, so the material can stretch. But the crosslinks do stop the chains from sliding completely freely. For the material to change shape, the crosslinks have to be stretched, distorted, and sometimes broken and rearranged. When the material is done stretching, the crosslinks return to their original shape, giving the material both strength and elasticity.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)Then there’s the self-healing. If you poke a hole in the material, iron atoms on one side of the hole are attracted to oxygen and nitrogen atoms on the other, reforming atomic bonds and closing up the hole within 72 hours. Even when the researchers cut the polymers into two separate pieces, the cut edges ends rejoined almost perfectly if they were placed in contact, recovering almost all of their strength and 90% of their stretchability, even at temperatures as low as -20°C.When the researchers applied an electric field across the polymers (similar to how muscle tissue is activated), the material’s length increased rapidly by about 2%. When the field was turned off, the material returned to its original size.One notable weakness of the material is that the change in size after the electric field was applied is still small: Even though the material can normally be stretched up to 45 times its original length and still return to its original shape, its change in size when the field was turned on was much smaller than that of real muscle (which can shorten by up to 40%). This would mean that those robotic legs couldn’t bend nearly as well as natural ones.“In our case, the goal was not to make the best artificial muscle, but rather to develop new materials design rules for stretchable and self-healing materials,” Bao explains. “Artificial muscle is one potential application for our materials.” Bao’s team is now planning further work on increasing the effects of electric fields.“It’s very interesting and extremely elegant work,” says polymer chemist Marek Urban of Clemson University in South Carolina. He says the polymer could eventually be used to make the synthetic muscles needed to move artificial limbs, either to replace missing ones for disabled humans or to allow robots to move things like a human can. He also says the material might have other applications. Materials that expand and contract in response to an electric field are often used as pressure or strain sensors, sometimes self-correcting ones. Self-healing could be useful when sensors have to be placed in extreme conditions such as in space, where repair is sometimes difficult or impossible. “If a material has to be placed in an environment where there’s a potential for damage [and] that material self-repairs, that’s a huge advantage,” Urban says.last_img read more

Cathay Pacific CEO resigns after Beijing pressure

HONG KONG — The CEO of Cathay Pacific Airways has resigned following pressure by Beijing on the Hong Kong carrier over participation by some of its employees in anti-government protests.Cathay Pacific said Rupert Hogg resigned Friday “to take responsibility” following “recent events.”The company chairman, John Slosar, said in a statement the airline needed new management because events had “called into question” its commitment to safety and security.On Monday, Hogg threatened employees with “disciplinary consequences” if they took part in “illegal protests.’Last week, China’s aviation regulator said Cathay Pacific employees who “support or take part in illegal protests, violent actions, or overly radical behaviour” are banned from staffing flights to mainland China.The Associated Press read more

Lightning may have started fire

Lightning may be the cause of a fire Saturday evening that destroyed a home on Robinson Road in Brant County.Damage is estimated at more than $1 million, said Brant County fire chief Geoff Hayman.“The fire had a significant head start when we arrived,” said Hayman.“We found no nearby fire hydrant and a 300-metre long driveway so there wasn’t a lot of room for our tankers. Our guys did a really good job under the circumstances.”Hayman said five county stations responded to the fire, with up to 45 volunteer firefighters working the tankers and an aerial truck.Robinson Road runs off Highway 24, west of Brantford and between Paris and Burford.“We’re not sure of the point of origin but witnesses indicated there was a significant lightning strike in the area around that time.”There were no residents in the home when the fire began. An alarm system detected some sort of problem and sent a warning to an alarm company.Hayman said the home had an attached garage that housed valuable antique vehicles. While the garage wasn’t burned, some of the ceiling and roof collapsed inward on the vehicles, he said.“They may be salvageable.”Hayman said the firefighters brought in an excavator to take apart the burning embers and ensure the fire couldn’t flare up again.“The Fire Marshal’s Office has been notified but, once you use an excavator, the ability to pinpoint a cause is limited.”Mohawk College photography student Shaun Quin was passing the fire Saturday evening and stopped to take photos.“I’ve can’t overstate the amazing teamwork between the first-responders, the police, hydro workers and workers from Union Gas. They had amazing co-ordination,” said Quin.“I left there thinking there could not be more capable people handling the situation.” read more

Ohio State professors organization making waves in sports research

Trevon Logan, an associate professor of economics at Ohio State, poses for a photograph inside his office at Arps Hall. Logan is one of the head researchers involved with the recently created Sports and Society Initiative at OSU. Credit: Courtesy of Trevon LoganA newly formed organization of Ohio State professors and other distinct faculty are challenging the traditional views of sports through in-depth research.The Sports and Society Initiative at OSU performs data analytics research to look at the way sports interact with the economy and society. The collective, which is composed of professors from five different majors, began in October. Despite being just five months old, SSI is already making headway through its multiple areas of expertise. Its members work toward developing new findings in the realm of sports research. Janet Box-Steffensmeier, the divisional dean for social and behavioral sciences in the OSU College of Arts and Sciences, is one of the driving forces behind SSI. Her role is to support the ideas and research done by professors, as well as galvanize outside donors, public officials and OSU alumni about this newly thriving organization.“(SSI) wants Ohio State to be the place to go for research on sports,” Box-Steffensmeier said. One of the leading professors on the forefront of SSI’s research is Trevon Logan.Logan, an economics professor who has been at OSU for more than 10 years, is the group’s main member that is deeply examining the correlations between sports and economics.“There are social science and policy aspects to sports,” he said. “They are just never brought up in the public sphere and talked about.”That is where SSI comes in. Its goal is to challenge the conventional wisdom of sports, as well as provide a platform in which research and discussion of sports issues can take place.“We want to make Ohio State sports-related research as prominent as the sports themselves,” Logan said.His recent research dove deep into the issues of compensation for student-athletes. The professor began delving into years of OSU data in order to analyze the effects the school’s recruits have on the number of wins and bowl game appearances.Thereafter, Logan took that information of wins and appearances and reviewed their connections to the university’s football-related revenue. The research revealed, based on revenues and expenditures, that a five-star recruit is worth about $900,000 for a university, Logan said. That number dips to $400,000 for a four-star recruit.“If you think about that number based on a five-star and four-star recruit’s salary in the NFL, those are honestly not too crazy of numbers,” Logan said.Next, Logan examined the data around transferring and the frequency of players departing early for the professional ranks across FBS schools.This research found that 15 percent of college football players will transfer to another university. The most common transfer position, Logan said, was the quarterback position. Additionally, the professor found that 11 percent of players will leave early for the NFL draft.“When these numbers were generated, I was shocked,” he said.SSI members will present this research — and more — in the coming months at a multitude of events regarding policy and economics in the world of sports.One of these events includes a forum centered on the pay-to-play model in high school athletics. The event is titled, “Pay to Play: Who’s In, Who’s Out and How Much?” and it is set to be held at 9 a.m. on Feb. 26 in Pfahl Hall room 202.Discussing the issue, Logan said, will be a panel of professors and politicians, such as Ohio Secretary of State Jon Husted, State Sen. Cliff Hite, Scott Grant, a professor at the University of Findlay and Ohio University Professor David Ridpath.“The goal of this forum is to discuss ways to increase participation in high school athletics without increasing the costs,” Logan said.A separate gathering is slated to be held on April 15 to dissect compensation for collegiate student-athletes. This function will present sports experts and OSU alumni from across the nation to examine this subject, Logan said.  Arguably the crown jewel of the panel will be Vince Doria, an OSU graduate and senior vice president and director of news at ESPN.Research SSI has conducted concerning this issue will be presented at the forum, too, Logan said.“(SSI and the panel) want to discuss the implications of compensation for student-athletes and what it would mean for the future of college athletics,” he said.Box-Steffensmeier possesses similar goals for these cutting-edge gatherings. Her hope is to further dialogue about these important national issues while promoting the faculty involved with SSI and the research it has performed.Additionally, she said she also wants to intrigue students who have a passion for sports and encourage them to contact those involved with SSI. She said she believes that students doing this could spark new ideas and issues to research.She said she holds big aspirations for the future of SSI. “I would love major news outlets to have a hot sports topic and know that we have an outstanding roster of faculty and students to call upon about the issue,” Box-Steffensmeier said.SSI might be in its early stages, but the collective is taking giant leaps, reaching new, unexplored heights in the vast expanse of college athletics. “Ohio State is on the move in regards to sports-related research,” Logan said. And with the passion, intelligence and ability of this small group of faculty members, there is no telling just how influential its work might be. read more

Des coeurs humains développés en laboratoire

first_imgDes coeurs humains développés en laboratoirePour la première fois, des chercheurs américains ont réussi à recréer en laboratoire des cœurs humains. Ils espèrent les voir battre d’ici quelques semaines.   C’est une première. Les chercheurs de l’Université de Minneapolis dans le Minnesota sont parvenus à développer en laboratoire des coeurs humains. En 2008, ils avaient déjà recréé des cœurs de rat et de cochon en utilisant des cellules souches et des cellules musculaires issues du cœur de l’animal. Une expérience réussie qu’ils ont décidé de recommencer, cette fois-ci en utilisant des cellules humaines. Comme pour les animaux, les coeurs se sont très bien développés.  À lire aussiInfarctus : définition, signes et symptômes, causes, comment réagir face à un infarctus ?Dans le cas de l’expérience animale, les organes étaient parfaitement fonctionnels et avaient commencés à battre. Ils étaient toutefois restés trop chétifs pour être greffés. De même, les cœurs humains ne pourront pas être transplantés. Mais l’équipe espère “qu’ils vont montrer des signes de battements dans les prochaines semaines” comme l’a indiqué le Dr Doris Taylor, experte en médecine régénérative qui a conduit les recherches. Si l’opération réussit, il sera alors possible, dans le futur, de greffer des cœurs issus des propres cellules des patients. Une technique qui éviterait entre autres, les rejets susceptibles de se produire et les traitements normalement nécessaires lorsque l’organe transplanté provient d’une autre personne. Pourtant, la tache s’annonce difficile comme l’a expliqué au Sunday Times le Dr Taylor : “Il y a de nombreux obstacles à franchir pour générer un cœur tout à fait fonctionnel, mais je prédis qu’il pourrait être possible de faire grandir des organes entiers pour des transplantations”.Le 5 avril 2011 à 16:03 • Maxime Lambertlast_img read more

Solskjaer keen to rotate his squad

Thermaxs shrinking domestic order inflows raise concerns IDBI Capital Markets

first_imgThermax, the Pune-based company that makes and sells boilers, water and waste management equipment, heating and cooling machinery, and industrial chemicals, reported a fall in its domestic order inflows during the September (Q2) quarter, a trend that is expected to stay in the coming months this fiscal. The share price of Thermax closed at Rs 880 on Friday on the BSE. Thermax reported 11.29 percent fall in Group order backlog to Rs 4,579 crore as of September 30, 2016 as against Rs 5,162 crore at the end of September 30, 2015. At a standalone level, the decline was marginal to Rs 3,917 crore at the end of Q2 (down from Rs 4,006 crore). Fresh order inflows during Q2 did rise 36 percent to Rs 1,098 crore, while at a group level, the rise was 31 percent to Rs 1,241 crore. The company attributed it to “orders received from international market and from consumption-led sectors such as food, textiles and pharma,” implying falling business in the domestic market.”Thanks to lower base, the order inflows were up 31% YoY to Rs12 bn. Further, half of them were led by international. From competitive intensity to putative delays, there are too many variable that can adversely impact EBITDA,”  Rohit Natarajan, analyst at IDBI Capital Markets & Securities Ltd. said in a note.Thermax reported a marginal fall in net profit for Q2 at Rs 60 crore and 19.5 percent drop in revenues at Rs 871 crore on a standalone basis.The outlook for the company’s revenues and operating margin remain bleak in view of the prevailing business scenario, analyst Natarajan said.”With poor order inflow, we maintain de-growth in revenues till FY18. Key catalysts: (1) Order inflows; and (2) even when the cycle recovers, the competitive intensity is yet another aspect — we endeavor to actively monitor. With cost rationalization, like in the current quarter, in a base case scenario, a flat EBITDA over the next two fiscals cannot be ruled out,” he said in his note.Trends in select domestic and international busineses Thermax is poised to benefit from two significant developments but in a staggered manner, in addition to factoring in competition from rivals. “First, for NTPC, company (Thermax) is working on a first-of-its-kind project similar to compact linear Fresnel reflector. Such project, company opines, could add orders cRs780 mn/660MW. A good sigh of relief is lower competitive intensity. And the total market size, at the best, may not be more than Rs16-20 bn, we opine. Yet without commissioning of first, which is scheduled for 12 months fast tracking, the new projects risks a delay all the way to FY18,” Natarajan wrote.”Second, though Govt. of Thailand has approved 25 new sugar mills, TMX has identified 19 that would entail separate buying of power and sugar plant equipment. For these bagasse-based boilers, we think the total opportunity, addressable to TMX, may not be more than Rs 24 billion. With five players across the globe, the competitive intensity is low, company reckons. Yet five is a stretch, we feel. Though the first order is placed, the second tranche could be spread over next 36 months,” he added in his note.The share price target for Thermax is Rs 727, translating into a potential downside of about 17 percent from the current market price.last_img read more

We don’t want to see any recurrence of such incidents,” Actionaid country director Farah Kabir told the programme.Prothom Alo, in association with Actionaid, organised the roundtable styled ‘Political Manifesto preventing violence against women: reality and solutions’ at its Karwanbazar office.Accusing the parties of not taking the issue of violence seriously, the rights activists pointed out that the parties pledge many positive things in their manifestos, but do little to implement their pledges once they assume office.They said legacy of political violence during the elections, and use of money and muscle power prevent women from actively participating in politics.Khushi Kabir, coordinator of non-government organisation Nijera Kori (We ourselves do), said number of woman candidates seems to be much lower this year than that of the previous elections.Women’s activist organisation Naripokkho’s member Shireen Huq lamented absence of democratic environment in the country as a cause for concern for women as well.“Strengthening the women’s voice in every sector of the society is very much related with presence of a stronger democratic environment,” she said blaming the current atmosphere for violation of women’s rights.Supreme Court lawyer Tania Amir said, “We don’t want to see some seats being offered to women only as cosmetics; we rather want to see more and more competent women doing politics directly.”UNDP’s Sharmila Rasul said the womenfolk should ask the political organisations how many of their pledges to ensure rights of women in manifestos were implemented.Women and children affairs ministry official Abul Hossain, Jatiya Nari Nirjaton Protirodh Forum’s (JNNPF) chair Momtaz Ara Rumi, Bangladesh Mahila Parishad’s international affairs secretary Rekha Saha, additional deputy commissioner (ADC) of Bangladesh Police Nusrat Jahan Mukta, chief news editor of News24 channel Shahnaj Munni, Icddr’b gender and diversity specialist Farjana Shahnaz Majid and Actionaid’s Kashfia Feroz also spoke at the roundtable moderated by Prothom Alo associate editor Abdul Quayum.last_img read more

Group Reports Abuses By Law Enforcement That Allegedly Happened At The Border

first_imgPhoto: Border Network for Human RightsThe volunteers who conduct the interviews on which the report by the Border Network for Human Rights is based are trained by the organization, which says the interviews typically run 30 minutes or longer.The Border Network for Human Rights (BNHR) released this week a report that presents 38 incidents of abusive or problematic behavior by federal, state and local law enforcement agencies which have happened in El Paso, as well as in southern New Mexico.The report is based on the BNHR’s “Abuse documentation campaign” and the organization has been conducting the interviews that are presented in the reports since the beginning of the 2000 decade. According to the language used in the report, the abuses include intimidation, physical abuse, psychological abuse and verbal abuse, as well as family separation, harassment, prolonged detention and excessive use of forceThe first section of the report explains that volunteer “documenters” are trained to ask: “Who did What to Whom, When, and Where?” and that documentations are conducted through “live, in-person interviews that typically run 30 minutes or longer.”Specifically, the BNHR used more than 120 documenters that conducted interviews in more than 33 locations during the month of February.Incidents dating back to 2012That first section of the report also clarifies it presents incidents that occurred “as recent as April (of 2018) and as old as 2012.”Fernando Garcia, the BNHR’s founder and executive director, said all the incidents included in the report are based on “first person testimonials” and noted that, because of the “standards” the “documenters” use, some incidents were not included in the report because they were not “verifiable.”The way the report is structured, “documenters” have tried to reconstruct each incident based on the information provided by the person they interviewed. There is extensive information on some of the incidents reported –including, for example, the names of supervisors of the law enforcement agency in question— while the information about other incidents is as scarce as three lines of text.The report doesn’t include any official documents related to the interactions the interviewees spoke about.In the report released this week, the U.S. Border Patrol accounts for the highest number of incidents, with 11, and most of them –specifically nine— happened in New Mexico, not in Texas. The report notes that the Border Patrol, which is part of U.S. Customs and Border Protection (CBP), had zero incidents in the report that the BNHR released in 2013.Some of the incidents reported indicate that Border Patrol agents got inside homes and patios, apparently without having search warrants.Ramiro Cordero, a supervisor with CBP, indicated in an email sent to Houston Public Media that the United States Code grants Border Patrol agents “authority to investigate any instance where it is believed an illegal entry has been made.”“The U.S. Border Patrol has the legal authority to enter either private residential or commercial property within 25 miles from the border for the purpose of investigating potential violations of immigration law,” Cordero noted in his statement and added that “if an illegal entry has been determined to have been made, agents can enter a property while continuing to pursue the violators and continue their investigation without the need for a search warrant.”Photo: Google MapsAccording to the report by Border Network for Human Rights, most of the incidents that involved Customs and Border Protection personnel happened in the Zaragoza and Santa Fe border bridges. This file photo shows the Santa Fe bridge.U.S. Customs and Border Protection accounted for 10 incidents, all of them in Texas, at ports of entry. The most common incidents had to do with, according to language used in the report, “verbal abuse” and “degrading behavior,” but also “unfounded accusations,” “physical abuse” and “prolonged detention in secondary inspection.”Most of the incidents happened in the Zaragoza and Santa Fe border bridges.“Anecdotal allegations”Ruben Jauregui, a Chief CBP Officer who works in the El Paso office, said in an email that “anecdotal allegations that do not provide any specifics prevents CBP from commencing reasonable steps to examine assertions and address concerns” and added that “allegations are not facts.”Nonetheless, Jauregui indicated the CBP meets regularly with non-governmental agencies such as the BNHR to discuss “matters of mutual concern” and that “when presented with specific factual information we make every effort to investigate the matter and provide a response and/or explanation.”Garcia said he disagrees with Jauregui’s comment about “anecdotal allegations” and detailed that his group is in the process of assessing whether to file formal complaints. The report specifies that such complaints could be presented to the Department of Homeland Security’s Office of Inspector General, the Organization of American States and even to the United Nations.Immigration and Customs Enforcement (ICE) accounted for seven incidents. Three of them happened in Texas and, according to the report, “cases of family separation dominated the abuses.” Additionally, also according to the report, some ICE agents attempted to intimidate people they encountered and, in other incidents, they taunted the families of persons who were being detained.An ICE spokesperson said in an email that the agency “focuses its enforcement resources on individuals who pose a threat to national security, public safety and border security.”The statement from ICE also noted that the agency “no longer exempts classes or categories of removable aliens from potential enforcement” and added that “all of those in violation of the immigration laws may be subject to immigration arrest, detention and – if found removable by final order – removal from the United States.”RecommendationsThe report has a section with recommendations for all the law enforcement agencies it analyzes at the federal, state and local level, and emphasizes that Congress should enact legislation to make them more accountable.In that sense, the BNHR supports bills such as the “Border Enforcement Accountability, Oversight, and Community Engagement Act of 2017”, which U.S. Representative Beto O’Rourke (D-Texas) introduced last year, and the “Department of Homeland Security Accountability and Transparency Act”, which Senator Kirsten Gillibrand (D- New York) introduced in May.Speaking about the law enforcement agencies working at the border Garcia said “they need to be accountable to the communities.”The BNHR also recommends that the Texas Legislature repeals SB4, the state law that allows local law enforcement agencies to ask about immigration status in certain situations. Critics of the law have long argued it can cause racial profiling.You can read the BNHR’s report here: Sharelast_img read more

Physicist warns of problems with speeding up financial markets

Author, physicist and former editor, Mark Buchanan outlines technical issues with the global financial trading markets in a comment piece he has written for the journal Nature, where he suggests that more thought should be put into how the system evolves in the future because problems with it could cause very serious worldwide economic troubles.center_img Journal information: Nature © 2015 Tech Xplore Citation: Physicist warns of problems with speeding up financial markets (2015, February 12) retrieved 18 August 2019 from For most people, the global financial markets are a murky business, stocks and other commodities are bought and sold, by individuals, companies and most importantly traders every second that the markets are open. As technology has improved, the ability to buy and sell on any of the worlds’ markets (NYSE, Euronext, etc.) has become easy and commonplace. Technology has also changed the way trades are made, with big financial corporations relying on computers running sophisticated software to do the buying and selling for them—it all happens in milliseconds now. Over the past several years, it has become apparent that some corporations have found that the faster they can receive information from a market, process it and then send back a buy or sell order, the more of an edge they will have over competitors. This has led to a race of sorts, to see who can come up with the fastest system. In his article, Buchanan highlights many of the ways that businesses with deep pockets are speeding up their communications systems, such as installing laser systems on rooftops, and then asks if the move towards seeking the ultimate limit, the speed of light, is good for the financial markets, or the rest of the world’s economies.We all know about the dangers of automatic buying and selling by computers, “flash crashes” can cause massive hikes or drops in prices in milliseconds. Buchanan suggests speeding up communications ever more (such as with the new fiber cable currently being installed between New York and London) will likely result in more such crashes or perhaps cause something truly catastrophic in global markets at some point which could set off an economic collapse. He suggests that rather than take the wait and see approach, it would be better to create teams of computer scientists, economists, mathematicians, and perhaps others, to study the virtual ecosystems that are being built to better understand what is really happening, and perhaps, to build in safeguards to keep runaway systems from destroying the global economy.last_img read more
