After Easter attacks Sri Lanka mulls new fake news law

first_imgColombo: Sri Lanka’s government will introduce five-year jail terms for those caught spreading fake news and hate speech on social media, the government said Wednesday, following a surge in online vitriol and disinformation after the Easter suicide attacks. The cabinet of ministers approved a proposal by the acting justice minister, which will also see offenders fined one million rupees (USD 5,715), the government said in a statement. It did not immediately release a definition of the two offences, but said the penal code will be amended to introduce the new penalties.

Zac Brown Band Raises Record Amount For Camp Southern Ground

first_imgOn Saturday, October 14th the multi-platinum GRAMMY award-winning Zac Brown Band took the stage at the Southern Ground Amphitheater in Fayetteville, Georgia for the sixth annual Night of Candles benefit show in support of Camp Southern Ground.Zac Brown Band at the Southern Ground Amphitheater in Fayetteville, GeorgiaCredit/Copyright: Andy SappIn a record breaking night, the event helped to raise 1.7 million dollars for Camp Southern Ground.Camp Southern Ground is located on over 400 acres in Fayetteville, GA and will serve children ages 7-17, from all socioeconomic backgrounds, races and religions, with activities to challenge, educate and inspire campers. As an inclusive camp, Camp Southern Ground will bring together typically developing children, children with Autism Spectrum Disorders (ASD), learning and attention issues, social or emotional challenges, and those with family members serving in the military.The evening’s proceeds will help to support the build out of the first residential lodge on Campus. A large portion of the night was made possible by presenting sponsor Wells Fargo who made a generous donation to Camp Southern Ground to help with the construction of the lodge, which in the non-camp season will support military families and veterans, a cause Wells Fargo supports greatly.“By working together with Zac Brown Band, and Zac’s non-profit passion project Camp Southern Ground, we believe that together we can build a better homecoming for veterans, their families, and the communities we serve,” said Jerry Quinn, Wells Fargo military affairs program manager. “Wells Fargo is proud to support Camp Southern Ground through philanthropy and volunteerism, and we are excited about the groundbreaking for their new lodge that will offer enriching experiences for our veterans.”Nine weeks out of the year Camp Southern Ground will host campers, and when camp is not in session the state-of-the-art facilities will be used to partner with military and veteran support organizations, like Wells Fargo, who will deliver their programs on the campus.“Wells Fargo’s support for veterans in transition is aligned with our mission related to serving those who have served and sacrificed to protect our freedoms and keep us safe. We are so grateful for Wells Fargo’s generous donation which will go toward building our first essential residential lodge to house veterans while on campus and military children during our summer camps,” said Camp Southern Ground President and CEO, Mike Dobbs.Another successful evening for Camp Southern Ground means another step closer to opening the doors of the campus to children and families. It’s through the support of the community and partners like Wells Fargo that Brown’s passion project continues to grow.last_img read more

Ban urges Liberians to maintain peace despite electoral disagreement

He said he supported the joint efforts by the Economic Community of West African States (ECOWAS) and his Special Representative for Liberia, Ellen Margrethe Løj, to promote dialogue and build confidence in the electoral process.In Tuesday’s presidential run-off, the incumbent, Nobel Peace laureate Ellen Johnson-Sirleaf, is pitted against challenger Winston Tubman, who came second in the first round of the vote on 11 October, but media reports today indicated that Mr. Tubman has threatened to boycott the poll, alleging that it will not be fair.“The Secretary-General stresses the importance of peaceful, credible, transparent elections and reaffirms the readiness of the United Nations Mission in Liberia (UNMIL) to support the Liberian authorities, in accordance with its mandate,” said a statement issues by his spokesperson.Sixteen candidates, including Ms. Johnson Sirleaf, ran in the first round, with no one winning the necessary 50 per cent plus one of the total votes. Ms. Johnson Sirleaf garnered 43.9 per cent of the nearly 1.3 million votes cast, while Mr. Tubman got 32.7 per cent.The UN has maintained a peacekeeping force in Liberia since 2003 to bolster a ceasefire agreement ending a decade of war that killed nearly 150,000 people, mostly civilians, and sent 850,000 others fleeing to neighbouring countries. Its mandate includes helping to restore the rule of law and democratic processes as well as facilitating humanitarian assistance. It has a current strength of 7,775 troops and over 1,300 police officers. UNMIL provided logistical support for the delivery of voter registration materials to remote locations and helped the national police develop an integrated security and contingency plan in the run-up to the poll. It also deployed more ground troops and increased air patrols to improve security.Ms. Johnson Sirleaf won the first presidential election after the war in 2005, becoming the first elected woman head of State in Africa. 4 November 2011Secretary-General Ban Ki-moon today urged the people of Liberia to refrain from violence despite political disagreement, and encouraged them to ensure that peace is maintained during the second round of presidential elections scheduled for Tuesday. read more

At New York synagogue UN chief honours Holocaust victims pays tribute to

“My hope is that our generation, and those to come, will summon that same sense of collective purpose to prevent such horror from happening again anywhere, to anyone or any group,” Mr. Ban said in his remarks at the Park East Synagogue Memorial Service in honour of the victims of the Holocaust.The service comes ahead of the International Day of Commemoration in Memory of the Victims of the Holocaust. The Day is observed annually on 27 January, the anniversary of the liberation in 1945 of the Nazi concentration camp at Auschwitz-Birkenau, where over a million Jews and others perished during the Second World War.“The horror at Auschwitz played a formative role in defining the ideals and objectives of the United Nations. Like all of my predecessors as Secretary-General, I am determined to prevent any other such catastrophes and grave violations of human rights,” said Mr. Ban.He recalled his visit to Auschwitz last November, during which he was “profoundly saddened” by what he saw as he walked around the notorious death camp.“I walked through the infamous ‘Arbeit Macht Frei’ gate, and stared with disbelief at rooms filled with the shoes, dolls, suitcases and other belongings of those who were killed. I saw the ‘Book of Names’ – a list identifying more than 4 million Jewish victims – which filled one of the exhibition rooms yet contained just a fraction of the war’s toll.“I stood on the ramp where the transport trains unloaded their human cargo, where the awful moment of selection took place – where the quick flick of an SS commander’s index finger meant the difference between being killed immediately in the gas chambers and being kept alive only to be worked to death.”He was especially moved, he said, by a video showing European Jewish life in the 1930s – scenes of family meals and visits to the beach, musical and theatre performances, weddings and other rituals – all of it “savagely extinguished.”“Even today, the Holocaust is hard to grasp,” said the Secretary-General. “The cruelty was so profound; the scale so large; the camps spread so far and wide. The Nazi worldview was so warped and extreme – yet attracted so many followers.“As we have seen from Cambodia to Rwanda to Srebrenica, we have not eliminated the poison that led to genocide,” he added. Mr. Ban noted that in Syria, South Sudan and the Central African Republic, violence is taking on a “dangerous sectarian dimension,” and there is rising bias against migrants, Muslims, Roma and other minorities in Europe.“Each of us has a role to play in combatting intolerance, incitement and the manipulation of ethnic or religious identity that we see in conflicts and political campaigns. All those involved in atrocities – whether head of State or head of militia – should be held accountable,” he stated.“We must demand that those in power uphold their responsibilities to protect people. We must enact the laws and build the institutions that will uphold human rights.“And at this moment of disturbingly high rates of youth unemployment, we must make special efforts to inculcate universal values in the world’s young people. Otherwise, they could prove easy prey for extremists.”The 2014 observance of the International Day of Commemoration is centred around the theme “Journeys through the Holocaust” and recalls the various journeys taken during this dark period, from deportation to incarceration to freedom, and how this experience transformed the lives of those who endured it.The featured speaker at the 27 January memorial ceremony at UN Headquarters will be filmmaker Steven Spielberg, whose Shoah Institute for Visual History and Education was a landmark in preserving survivor testimony.The commemoration is organized by the United Nations and the Holocaust Outreach Programme, which has been working with teachers and students on all continents to promote tolerance and to warn about the consequences of anti-Semitism and other forms of discrimination. read more

16yearold remanded for farmers murder

Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Related A teenager was on Thursday remanded to the Juvenile Detention Centre when he appeared at the Georgetown Magistrates’ Court earlier on Thursday to answer to a murder charge.The 16-year-old was not required to plead to the indictable charge which alleged that on October 12, 2016, he murdered Abraham Wilson, a farmer, at Cacique Creek, North West District over a drunken quarrel, and then fled the scene.The court heard that on the day in question, Wilson and the teen were imbibing when the argument between the two began. The young man reportedly stabbed Wilson to the left side of his neck, then left the man to bleed to death as he went into hiding.However, with his little strength, the now dead man allegedly ran across to a nearby mining camp where he managed to relate to them what had transpired, before succumbing to his injuries.It was only recently that police were able to apprehend the suspect after he was detained by a North West District village leader.The accused is expected to re-appear in court on November 17, 2017. read more

Le CCNE autorise le dépistage rapide danomalies génétiques

first_imgLe CCNE autorise le dépistage rapide d’anomalies génétiquesLe Comité consultatif national d’éthique (CCNE) a donné son feu vert pour que les nouveaux tests de détection de l’anomalie génétique par simple prélèvement de sang maternel puissent être pratiqués en France.Le CCNE, Comité consultatif national d’éthique, en autorisant les nouveaux tests de détection de l’anomalie génétique par simple prélèvement de sang maternel, souhaite limiter le recours à l’amniocentèse jugée trop invasive. En effet, selon le Comité, les nouveaux moyens diagnostics de la trisomie 21, qui devraient être bientôt généralisés, “ne posent pas de problème éthique, au contraire, c’est un progrès, un avantage pour les femmes enceintes”.Un test moins dangereux Ces tests se basent sur des analyses de l’ADN fœtal qui circule dans le sang de la mère, dès la 11e semaine d’aménorrhée. Ils ne nécessitent donc pas de ponction de liquide amniotique qui sont dangereux et peuvent provoquer la perte de fœtus. “Le dépistage actuel conduit à faire un caryotype [analyse des chromosomes] chez 24.000 femmes enceintes à risque qui, dans 90 % des cas, s’avère négatif” et entraîne 80 à 240 pertes fœtales induites par les ponctions invasives, explique le professeur Ameisen, président du CCNE.De plus, les nouveaux tests, plus efficaces, permettraient d’éviter des gestes invasifs comme l’amniocentèse à 22 000 de ces femmes par an, rapporte Enfin, ils peuvent être réalisés suffisamment tôt pour que la décision d’interrompre une grossesse puisse intervenir dans les délais légaux de l’IVG. On parle parfois de tests ultra-précoces.Un Prenatest qui devra faire ses preuves Toutefois, Patrick Gaudray, généticien chercheur membre du CCNE, souligne que ces analyses n’offrent pas autant de certitude que celle apportée par caryotype de cellules fœtales. Le taux de faux positifs est de 0,2 % et, dans 5 % des cas, les résultats ne sont pas interprétables pour des raisons techniques. Ainsi, ces tests ne pourront devenir de véritables instruments de diagnostic que lorsque leur taux de faux positif sera encore plus proche de zéro et qu’ils n’auront donc plus besoin d’être confirmés, explique le Comité.À lire aussiBioéthique : les propositions du rapport Leonetti Par ailleurs, la Fondation Lejeune estime que le Comité d’éthique “valide la modernisation de l’éradication des trisomiques”. Pour le professeur Ameisen, la question qui se pose est de savoir la place que la société accorde aux handicapés, physiques, psychiques, et aux gens différents. Il estime que la France n’est pas à la hauteur dans ce domaine, y compris en matière de recherche.Enfin, ce PrenaTest, d’un prix estimé à 1.250 euros par la société allemande LifeCodexx qui le commercialise, pourrait coûter jusqu’à un milliard d’euros s’il est proposé à toutes les femmes enceintes. Néanmoins, là où ces tests sont déjà autorisés, les prix sont moindres et la société belge, Gendia (qui représente la société californienne Natera), en propose à 850 euros. Par ailleurs, le CCNE anticipe l’arrivée d’autres tests qui permettront d’analyser le génome entier du fœtus cette fois. Ils seront plus rapides et plus économiques à faire, indique la scientifique Dominique Stoppa-Lyonnet.Le 26 avril 2013 à 11:50 • Maxime Lambertlast_img read more

Gambia Government Gives Title Deed To Gina Bass

first_imgBy: Muhammed S BahGina Bass, the 24-year-old Gambian Olympian who won gold in the All Africa Games, which ended in Morocco last week, on Friday 9 September 2019, received a title deed from President Adama Barrow at Statehouse. Bass and other Gambian athletes participated in the just concluded African Games in Rabat, Morocco. These athletes including the Gambia Volleyball players on Friday met at the statehouse to receive title deeds and cash amount of D50,000, a message on the Statehouse official Facebook Page said. It said, “President received The Gambian team to the games at the State House to personally congratulate them for their exceptional performance and putting the name of the country on the athletic world map.” It added, “While Gina Bass and the volleyball players, who won gold were given land, other players in the Gambian delegation to the Africa Games each received D50, 000,” the message said. The 24-year-old sped past defending champion and Africa’s fastest 200m athlete Tallou of Ivory Coast to win gold with an impressive timing of 11.13 seconds, a season-best. The performance saw her beat 11.38 seconds feat over the weekend in the semi-finals. Earlier in the 100m race, she trailed behind Tallou coming second and winning a silver medal. This became the tiny West African nation’s second gong after the beach volleyball team snatched gold in their encounter against Morocco in the All Africa Games. During an interview with an international media, Gina described herself as the poorest Olympian, saying that is what people called her. She said she did not even have a plot of land.last_img read more

Infosys hits a 3year low in recruitment hiring falls 65 in FY2017

first_imgAn employee speaks on a mobile phone as she eats her lunch at the cafeteria in the Infosys campus in the southern Indian city of Bangalore September 23, 2014.Reuters fileLarge-scale recruitment by Indian IT services companies is clearly a thing of the past if numbers are anything to go by. With global headwinds such as weak economic growth and increasing protectionism displayed by the US under President Donald Trump such as tightening of H1-B visa norms, the situation could get tougher for aspiring IT job-seekers. Full-year and Q4 results declared by India’s second-largest IT software services exporter Infosys show that company’s net employee addition in 2016-17 was 6,320, down 64.6 percent from 17,857 in 2015-16 and 15,782 in 2014-15. The four-year low was 3,717, in 2013-14. At a gross level, Infosys added 44,325 employees in comparison to 52,545 in 2015-16, including a fall in lateral recruitment to 18,979 employees in 2016-17 from 24,719 in the preceding fiscal.The company’s utilisation, in contrast, saw a new high, according to the management. “Attrition declined during the quarter reflecting our focus on better employee engagement. Utilization during Q4 reached 82% which is the highest in Q4 over the past several years”, U B Pravin Rao, COO, said in a statement.Infosys declared its Q4 and FY2017 results on Thursday.It is worth recalling that the slowdown in recruitment by IT companies was evident in the December 2016 (Q3) quarter also, with net hiring coming in at 13,100 employees for four companies — Infosys, TCS, Wipro and HCL Technologies.The net addition for TCS and Wipro was 6,978 and 4,891 employees, respectively, while Infosys reported a fall of 66, heralding a new trend characterised by increasing job automation, artificial intelligence (AI) and possible restrictions on H-1B visas by the Donald Trump-led US administration. HCL Technologies saw its employee headcount go up by 1,297 in December quarter.A few weeks ago, it was reported that Cognizant Technology Solutions (CTS) was planning to lay off as many as 10,000 employees, though the reasons were not specified. The company had an employee strength of 2,44,300 employees worldwide, including 1,55,000 in India, where it has development centres spread across Mumbai, Bangalore, Chennai, Coimbatore, Gurgaon, Hyderabad, Kerala, Kolkata and Pune.  Infosys fact sheet for FY2017.Here is the data showing employee utilisation in Infosys: Infosys fact sheet for FY2017last_img read more

Energy harvesting skin generates power from air conditioners

first_img The researchers, Soobum Lee from the University of Notre Dame in the US and Byeng Youn from Seoul National University in South Korea, have published their study on the EH skin in a recent issue of Smart Materials and Structures and IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control. The research was partially supported by the POSCO Genesis Program.“EH skin is a new and innovative design paradigm for vibration and thermal energy harvesting,” Youn told “The EH skin was proposed to overcome the disadvantages of a traditional cantilever-type EH device and enables a power-generating skin structure. The cantilever-type EH devices require a bulky device fixture, resulting in significant energy loss due to imperfect clamping. To the contrary, the EH skin enables a compact and highly efficient EH implementation as a part of a vibrating structure.”The EH skin works by taking advantage of the piezoelectric effect, which is the ability of some materials to produce electricity when subjected to mechanical stress. Previous research has shown that PZT (lead zirconate titanate) has the highest energy conversion efficiency compared to other piezoelectric materials. In the new study, the researchers designed and fabricated a skin made of thin PZT patches, which are directly attached to a vibrating surface using a conductive epoxy. As the researchers explained, attaching thin piezoelectric patches is a well-known method for vibration control. However, the patches have never been used to harvest energy, as far as the researchers know.In their experiments, the researchers used the piezoelectric skin to harvest the vibrations of a condensing unit in an outdoor air conditioner. They optimized the topology and the shape of the piezoelectric skin so that it would convert the condensing unit’s vibrations into electricity as efficiently as possible. The design concept is based on a segment-type design scheme, introduced by the researchers in an earlier study, that segments piezoelectric patches to eliminate the energy cancellation effect.

( — Devices that harvest ambient energy from the surrounding environment have become popular since, for some applications, they eliminate the need for batteries that must constantly be replaced. One of the most widely available forms of ambient energy is vibration, which occurs in buildings, machines, bridges, staircases, and the human body, among other places. The most common type of device used to harvest vibration energy is the cantilever, which generates electricity by bending. In a new study, researchers have developed an energy harvesting (EH) device in the form of a flat skin rather than a cantilever, and have shown that it can generate enough power to operate multiple wireless sensor nodes. When testing the skin, the researchers found that it could generate power at an average of 3.7 mW, which is sufficient for operating wireless sensor units. As the researchers explained, self-powered wireless sensors could eliminate the need for battery replacement, leading to significant cost savings.“According to the US Department of Energy, maintenance costs for battery use in wireless sensor applications are estimated at $80-500 per replacement, including labor, which exceeds the sensor’s cost,” Youn said. “At the same time, about half a billion wireless sensor nodes were consumed by 2010, according to ON World, and this consumption will continue to grow substantially over the years. If EH skin is successfully implemented for self-powered wireless sensors, sustainability and maintainability will be significantly improved with a great economic gain.”Some of the applications of wireless sensors include the structural health monitoring of buildings as well as building automation systems, which monitor and control the mechanical and lighting systems in a building.“Building automation is one of the key research areas in the future that can enhance the energy sustainability of buildings by reducing electric energy consumption in lighting by 60%, in climate control by 45%, and in heating by 25%,” Youn said, citing a 2007 LonMark survey carried out by researchers at Technical College Biberach in Germany. “This is possible by monitoring the temperature, humidity, and motion using self-powered wireless sensors. The application of the self-powered sensors to the prognostics and health management area will enable smart health monitoring systems, which are free from battery replacement, to anticipate system failure in advance and make an optimal decision on maintenance. This will reduce maintenance costs significantly in many engineering fields, such as (nuclear) power plants, transportation, buildings, automotives, and defense applications.”In the future, the researchers plan to utilize multiple vibration modes in the EH skin to significantly enhance the power conversion efficiency. They also plan to develop a multifunctional EH skin that can perform energy harvesting, energy storage, noise reduction, and load carrying. Future applications could also include using the EH skin in aircraft and ground vehicles. More information: Copyright 2010 All rights reserved.

Samsung defends Android Galaxy S3 PenTile display

( — So what’s a hot new Galaxy S3 smartphone doing with a PenTile AMOLED display like this? That is a question that surprised developers and smartphone blog sites earlier this month when Samsung announced in London its new Galaxy S3 with a 4.8-inch 720p resolution display that uses a PenTile subpixel layout. Expectations were that the Galaxy S3 would carry another type of upgraded display The PenTile design had drawn disappointed reviews when it had earlier appeared on the Galaxy Nexus phone. This week, however, a Samsung spokesperson stepped forward to explain why PenTile was still chosen: Samsung wants the S3 phone displays to last longer. Samsung’s Philip Berne, a marketing manager, discussed the PenTile instead of RGB matrix decision. (RGB stands for “red green blue,” referring to the subpixel matrix used in displays. The PenTile pixel system uses sub-pixels in a different formation than do RGB displays.)Berne told MobileBurn that the choice came down to durability and longevity. Samsung, he said, determined that PenTile AMOLED displays have proven to be more reliable than those with RGB layouts. Displays that use AMOLED technology have a tendency to deteriorate over time. Blue subpixels on AMOLED displays degrade the fastest, quicker than the red or green subpixels. With a PenTile layout, the subpixels are arranged RGBG (red, green, blue, green), so they feature more green subpixels and fewer red or blue subpixels than an RGB format.As a result, AMOLED displays with a PenTile layout have a longer lifespan than those with RGB layouts. Those who have panned the PenTile arrangement in the past complained that the screen does not look as crisp as an RGB display and that, with the PenTile display, images may appear fuzzy around the edges. Berne, however, pointed out in MobileBurn that improvements were made. He said that, in comparison with the 4.65-inch 720p Super AMOLED screen on the Google Galaxy Nexus, the Samsung 4.8-inch display on the Galaxy S3 features smaller gaps in its subpixel matrix, to minimize fringing effects in a PenTile layout.Still, it seems that the PenTile decision this week has generated mixed reactions, if not emotions, from smartphone bloggers and developers. “No plus here,“ was one reaction to the news that the panel is featuring a PenTile RBGB pixel arrangement. Another comment was “Nice processor, shame about the PenTile.” Longevity may be a bigger plus, however, for average Samsung consumers than for a more demanding, pixel-sensitive, user base. What’s more, favorable reactions among Samsung Galaxy S3 reviewers were also forthcoming. They said they found no problem created by the display design.“We really could not see any issues with the screen,” wrote Dan Seifert in MobileBurn. Elsewhere, several Android forum contributors said that PenTile effects can only be seen if you are really looking for them.

First use of VLBI to focus on a single star system for

first_img More information: The First Very Long Baseline Interferometric SETI Experiment, arXiv:1205.6466v1 [astro-ph.IM]AbstractThe first Search for Extra-Terrestrial Intelligence (SETI) conducted with Very Long Baseline Interferometry (VLBI) is presented. By consideration of the basic principles of interferometry, we show that VLBI is efficient at discriminating between SETI signals and human generated radio frequency interference (RFI). The target for this study was the star Gliese 581, thought to have two planets within its habitable zone. On 2007 June 19, Gliese 581 was observed for 8 hours at 1230-1544 with the Australian Long Baseline Array. The dataset was searched for signals appearing on all interferometer baselines above five times the noise limit. A total of 222 potential SETI signals were detected and by using automated data analysis techniques, were ruled out as originating from the Gliese 581 system. From our results we place an upper limit of 7 MW/Hz on the power output of any isotropic emitter located in the Gliese 581 system, within this frequency range. This study shows that VLBI is ideal for targeted SETI, including follow-up observations. The techniques presented are equally applicable to next-generation interferometers, such as the long baselines of the Square Kilometre Array (SKA). Citation: First use of VLBI to focus on a single star system for signs of life comes up empty (2012, June 5) retrieved 18 August 2019 from Ruling out star systems is in some sense a matter of semantics, as the authors note. It could be that a planet inhabited by some form of life just isn’t broadcasting radio waves, or maybe is broadcasting but not at the frequency the team is looking at. They point out that had intelligent life forms light years away been looking at our planet just seventy years ago, they would have come up empty as well.The paper documents the attempt by the Australian team (which is affiliated with the Search for Extra-Terrestrial Intelligence (SETI) project) back in 2007 to search for signs of life in a new way. Prior to this project, astronomers used radio telescopes that simply swept the sky looking for interesting signals. In this new approach the team focused on one star system which is thought to have two planets of the kind that might hold some form of life, using VLBI, which is where several telescopes are strung together virtually to create one large system. Such systems are better able to discern the difference between signals from other sources (such as our own satellites) versus ones that come from the source that is being studied. In all, the team detected 222 signals, all of which turned out to be from places other than Gliese 581, the star under study. They’re not disappointed however; they say their work proves very clearly that VLBI will make a fine tool for studying exoplanets that have been found in recent years by other teams using other technology, and because this search technique costs so little, they don’t see why it can’t be used to study every single possibility, until hopefully one day some team finds what the SETI group has been looking for all along. Definitive signs of intelligent extra-terrestrial life. Journal information: arXiv Explore further © 2012 Phys.Org Binary star system found by following gamma-ray signal , Astronomical Journal ( — Astronomers in Australia have reported on their findings in their paper posted on the preprint server arXiv, regarding their use of Very Long Baseline Interferometry (VLBI) to study radio signals emitted from a single star system some 20 light years away. In their paper, soon to be published in the Astronomical Journal, the researchers say that the absence of signals from the studied star system was not unexpected as the odds of finding signals from intelligent beings when aiming at any given star system are not good when noting that there are billions to choose from. Despite this, they report feeling optimistic as the project proved that such technology could be used to rule out other star systems in the future.
