PM in the list of top 100 global thinkers

first_imgPM in the list of top 100 global thinkersPrime minister Sheikh Hasina has made her room in the list of top 100 global thinkers as the famous US-based Foreign Policy journal came up with a register of world leading thinkers.“Sheikh Hasina has responded to the greatest security challenge facing Bangladesh with a generosity . . . Rather than turn away the approximate 700,000 Rohingya who fled persecution in Myanmar, Hasina welcomed them and allowed them to remain in her country,” the journal wrote justifying their decision for incorporating in the list of its Current Issue: Winter 2019.Sheikh Hasina has been named among the 10 top global thinkers in the category “Defense and Security”.Referring to the background of the list, the Foreign Policy said they selected the leading global thinkers cautiously considering their stake in shaping the world mind.“In a year of worldwide economic crisis and dangerous wars, of radical innovation and newfound realpolitik, street revolution and blunt rhetoric, we could think of no better way to make sense of it than through the big ideas of those who shape our understanding of the world,” the article read.last_img read more

Attorney Files Federal Complaints Over Reassignment of Longtime HISD Principal

first_imgLaura Isensee Attorney Scott Newar speaking on the reassignment of Bertie Simmons.Attorney Scott Newar has filed two federal complaints against HISD, saying its reassignment of longtime principal Bertie Simmons violates her civil rights. At a press conference downtown he argued the reassignment reveals age and race discrimination and believes it’s part of a pattern to replace white principals like Simmons on the east side with Latino leaders. Newar had asked for Simmons to be reinstated at Furr high school this week.Laura IsenseeAttorney Scott Newar speaking on the reassignment of Bertie Simmons. Instead the district has expanded its investigation into other areas like general administration and grade changes. What’s more he says several other employees including an IT specialist, a program manager and police officer have been summarily Transferred or told not to report to campus.“HISD has an obligation to investigate when there have been allegations of misconduct. Dr. Bertie Simmons has been temporarily reassigned while HISD investigates the allegations. HISD will respond to the EEOC and the Department of Justice complaints filed on behalf of Dr. Simmons, and denies any allegations of a pattern and practice of discriminatory treatment against employees,” said HISD in a statement.

Scientists create purplewinged butterflies in six generations

first_imgThe team says engineers could use these findings when designing devices that tune color, trap light or steer light beams. Journal information: Proceedings of the National Academy of Sciences When the researchers examined the wings that had changed color, they discovered that the thickness of some of the scales had changed. This altered the wavelengths of light the wings reflected. They studied the wings of B. sambulos and B. medontias, which naturally have wings that reflect violet light, and found that some of their wing scales were similar in thickness to those that had changed in the purple-winged B. anynana. However, the types of scales that reflected violet light in B. sambulos and B. medontias were different from the type of scale that had changed in B. anynana.Monteiro’s team believe their experiment shows that butterfly wing colors can evolve very quickly and that natural selection could play an important role in the development of wing color. For example, butterflies could use wing color to identify other butterflies of the same species or to influence mate choice. Explore further (Phys.org) —Scientists have used selective breeding to create purple wings on the normally brown-winged butterfly Bicyclus anynana. Antonia Monteiro and her colleagues selected butterflies with wing scales that reflected light closest to the wavelengths that produce the color violet and bred them. After six generation of breeding, the researchers produced butterflies with wings that had changed structurally to reflect violet light. The research appears in the Proceedings of the National Academy of Sciences.

Wasik, DOI: 10.1073/pnas.1402770111AbstractBrilliant animal colors often are produced from light interacting with intricate nano-morphologies present in biological materials such as butterfly wing scales. Surveys across widely divergent butterfly species have identified multiple mechanisms of structural color production; however, little is known about how these colors evolved. Here, we examine how closely related species and populations of Bicyclus butterflies have evolved violet structural color from brown-pigmented ancestors with UV structural color. We used artificial selection on a laboratory model butterfly, B. anynana, to evolve violet scales from UV brown scales and compared the mechanism of violet color production with that of two other Bicyclus species, Bicyclus sambulos and Bicyclus medontias, which have evolved violet/blue scales independently via natural selection. The UV reflectance peak of B. anynana brown scales shifted to violet over six generations of artificial selection (i.e., in less than 1 y) as the result of an increase in the thickness of the lower lamina in ground scales. Similar scale structures and the same mechanism for producing violet/blue structural colors were found in the other Bicyclus species. This work shows that populations harbor large amounts of standing genetic variation that can lead to rapid evolution of scales’ structural color via slight modifications to the scales’ physical dimensions. The butterfly Bicyclus medontias displays violet-colored wing scales that evolved through natural selection. Credit: Antónia Monteiro Living things can produce color chemically or structurally. Those that produce chemical color create pigments that absorb certain wavelengths of light and reflect others. Organisms that produce structural color experience changes in their bodies, at the nanoscale level, that enhance the reflection of particular wavelengths.Butterfly wings have structural color. To understand how this color evolves, Monteiro and her team selectively bred B. anynana, a butterfly that normally has brown wings, in an attempt to create purple wings. Two close relatives of this butterfly, B. sambulos and B. medontias, have purple scales on the backs of their front wings. However, until now, no one has ever reported seeing any purple-winged B. anynana.To create purple wings, the team measured the wavelengths of light reflected from the wings of B. anynana specimens. They then selected and bred those butterflies whose wings reflected light closest to the violet spectrum. They performed this process six times in eight consecutive generations. As the breeding process continued, reflected wavelengths moved further toward the violet spectrum. By the sixth time, the butterflies had purple wings. © 2014 Phys.org This document is subject to copyright.

High Court stays order on eviction of hawkers in Sector V

first_imgKolkata: The state government on Monday informed the Calcutta High Court that hawkers in Salt Lake Sector V area will be relocated elsewhere only after the state has a hawker policy in place. Soon after hearing the state’s stand, the High Court stayed the process of evicting the hawkers encroaching upon the bus route of Sector V till August 30. The stay of Justice Debangshu Basak came in the wake of the Salt Lake Sector V Hawkers’ Welfare Association, moving the high court against the eviction order. Also Read – Rain batters Kolkata, cripples normal lifeThe next hearing in this regard will be held on August 23. The counsel appearing on behalf of the state claimed that the government is absolutely against forcible eviction and wants proper rehabilitation of the hawkers. Hawkers in Salt Lake Sector V were taken to two plots of land in the area on Saturday where the Nabadiganta Industrial Township Authority plans to relocate them. It may be mentioned that police wants the hawkers on Ring Road, the stretch from the SDF intersection in GN Block to Technopolis building to be vacated for smooth traffic movement. It may be mentioned that hawkers in Sector V had demonstrated by keeping their shops closed on Friday to protest the order asking them to clear three main thoroughfares or face eviction. They also allegedly prevented several delivery persons of app-based food delivery services on their way to offices in Sector V.last_img read more

BJP leaking false numbers on Pakistan air strike TMC

first_imgNew Delhi: The Trinamool Congress Saturday accused BJP ministers of “leaking exaggerated numbers” to the media about the casualties in the air strike in Pakistan. The Mamata Banerjee-led TMC also claimed that no statistics given by the central government can be taken “seriously”.Security forces have not officially attributed any number to those eliminated in the strike, Trinamool Congress national spokesperson Derek O’Brien posted on Twitter. “IAF has been very consistent: “No number”.So why did a BJP mantri or two leak exaggerated numbers? And Delhi media fell for the numbers. Can one take any statistics this govt gives out seriously? Journos? Or slaves to propaganda aka sources?,” he tweeted along with screenshots of TV news reports quoting sources as saying 200-300 Jaish-e-Mohammed terrorists were eliminated in the strike. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseLater in a statement, O’Brien accused BJP president Amit Shah and Prime Minister Narendra Modi of playing “divisive politics” over the issue. “Look who has the gall to talk about ‘vote bank politics’! Amit Shah and the BJP are the nastiest proponents of divisive and hatred politics. “We will not listen to his lectures on patriotism. Our armed forces belong to India, not to Modi-Shah-BJP,” he said. The comments from the TMC leader came a day after party chief and West Bengal Chief Minister Banerjee demanded proof from the government of the impact of the strike on a JeM camp across the border.

The train will leave for Pakistan from Delhi on Sunday, a senior railway official said. The announcement came a day after Pakistan released Wing Commander Abhinandan Varthaman. While Pakistan had cancelled its services right after an air strike by the Indian Air Force, India cancelled the operations of the Samjhauta Express on February 28. The Railway Board in an order had said all operations of the Attari Special Express, Delhi-Attari-Delhi, which together with the Pakistani line from Wagah-Lahore is known as the Samjhauta or Friendship Express, will remain cancelled. It had also said that the cancellation was due to “purely operational reasons”. Sources said after the missive about Pakistan’s resumption of services was conveyed to the board, it was decided that services on the Indian end will resume too. The train will start running from the Indian side on Sunday, while on the Pakistan side it will leave Lahore on Monday for its return journey, the official said.last_img read more

Its publicity mongering Mamata on Modis Mission Shakti announcement

first_imgKolkata: Prime Minister Narendra Modi’s announcement of India’s anti-satellite missile capability on Wednesday was “limitless drama and publicity mongering”, amounting to “gross violation” of the model code of conduct, West Bengal Chief Minister Mamata Banerjee said. The PM made the announcement ahead of the Lok Sabha polls to “reap political benefits”, Banerjee, the Trinamool Congress (TMC) supremo, said. “There is no great urgency in conducting and announcing the mission now by a government past its expiry date. It seems a desperate oxygen to save the imminent sinking of the BJP boat. We are lodging a complaint with the Election Commission,” she said. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata Addressing the nation on the demonstration of India’s anti-satellite missile capability, the prime minister said India had joined an exclusive club of space super powers by shooting down a live satellite, describing it as a rare achievement. “Today’s announcement is yet another limitless drama and publicity mongering by Modi desperately trying to reap political benefits at the time of election. This is a gross violation of Model Code of Conduct,” Banerjee tweeted. Also Read – Lightning kills 8, injures 16 in state Pointing out that research, space management and development “are continuous processes”, Banerjee said, “Modi, as usual, likes to take the credit for everything.” “Credit to those who really deserve it, our scientists & researchers,” she added. “India’s Mission Programme is world-class for many many years. We are always proud of our scientists, @DRDO_India, other research & space organisations,” she tweeted. The TMC had earlier criticised the prime minister for trying to “take the credit” of the achievement of space scientists in shooting down a live satellite. The party said this would not have any impact on the poll prospects of the BJP in the upcoming elections. “Narendra Modi should stop taking credit for the achievement or job done by others. Shooting down a satellite is the credit of our scientists. The Modi government in the last five years has failed to provide any relief to the people of the country,” senior TMC leader and West Bengal minister Firhad Hakim said. “So ahead of the elections, the BJP and Modi should stop these tricks to fool the masses. It won’t have any impact on the poll prospects of the BJP in the upcoming elections,” Hakim said. Modi said the action was not directed against any country and the satellite was a pre-determined target orbiting at an altitude of 300 km.last_img read more
