Muslim devotees offer prayer during Ramadan at Baitul Mukarraum National Mosque in Dhaka on 31 May 2019. Photo: Prothom AloThe holy Lailatul Qadr or Shab-e-Qadr, the holiest and most blessed night for Muslims, will be observed across the country tonight with due solemnity and religious fervor, reports UNB.Muslim devotees will spend the night seeking divine blessings for peace and progress for family and the country as well as the Muslim Ummah.According to the holy Quran, this is superior to a thousand nights as the Quran was revealed to the greatest Prophet Hazrat Muhammad (PBUH) in this glorified night to show mankind the path of worldly and eternal emancipation.The devout Muslims usually pass the night offering special prayers, recitation from the holy Quran, holding milad mahfil, zikr, and other religious rituals at mosques and in their houses.They will also visit graveyards to seek divine blessings for the departed souls of their near and dear ones.
Share The ridesharing company Uber is threatening to pull out of Houston over what it’s calling “burdensome” regulations. In a letter to City Council, Uber says the city’s requirements for drivers duplicate what the company already has in place, leading to a long and expensive process for people who want to work for the company. They say the city’s rules are making it difficult for the company to hire drivers for the city’s major events. The company has also sent the city a report detailing the economic impact of Houston’s regulations. Uber’s letter to Houston’s City Council Uber’s Report
Aly Raisman, captain of the gold-medal U.S. gymnastics teams at the 2012 and 2016 Olympics, says she was abused by former team doctor Larry Nassar.Raisman, 23, told CBS’ 60 Minutes in an interview airing Sunday that Nassar first treated her when she was 15. She says she spoke to FBI investigators about Nassar after the 2016 Summer Games in Rio.More than 125 women have alleged abuse by Nassar, who is in jail awaiting sentencing on child pornography charges and a trial on charges of sexual misconduct. Plaintiffs are also suing USA Gymnastics, the U.S. Olympic Committee and Michigan State University, where Nassar was a doctor and faculty member.Raisman said people have asked her why more of Nassar’s accusers didn’t lodge complaints about him earlier.“Why are we looking at why didn’t the girls speak up?” she says. “Why not look at what about the culture? What did USA Gymnastics do, and Larry Nassar do, to manipulate these girls so much that they are so afraid to speak up?”McKayla Maroney, Raisman’s teammate at the 2012 London Games, said last month that she had been abused by Nasser for years. “I had a dream to go to the Olympics,” she wrote in a statement on Twitter, “and the things that I had to endure to get there, were unnecessary, and disgusting.”Adam Glanzman/Getty ImagesOlympic gymnast Aly Raisman says she was abused by former USA Gymnastics team doctor Larry Nassar. She told CBS’ 60 Minutes that he began treating her when she was 15.According to the Lansing State Journal, Nassar’s attorneys have defended his actions — including breast massages and digital vaginal and anal penetration for up to 20 minutes as a time — as helpful medical treatments.His attorney tells NPR that due to a gag order in the sexual abuse case, he has no comment on Raisman’s accusations.In an interview with The Associated Press in August, Raisman didn’t want to say whether she had been abused by Nassar, but she called him “a monster” and blamed USA Gymnastics for not stopping him.“What people don’t realize is that this doctor was a doctor for 29 years,” Raisman told the AP. “Whether or not he did it to a gymnast, they still knew him. Even if he didn’t do it to you, it’s still the trauma and the anxiety of wondering what could have happened. I think that needs to be addressed. These girls, they should be comfortable going to USA Gymnastics and saying ‘I need help, I want therapy. I need this.’”This week, the governing body announced it had hired a new president and CEO, Kerry Perry. The previous president, Steve Penny, resigned in March amid criticism of how the organization handled the abuse allegations.In June, USA Gymnastics said it was adopting all 70 of the recommendations from an independent review of its policies related to sexual misconduct. Among the recommendations is a database that will track coaches dismissed from member clubs, and requiring clubs to report complaints to authorities immediately.In a statement to 60 Minutes, USA Gymnastics pointed to its new guidelines and said it “is very sorry that any athlete has been harmed … we want to work with Aly and all interested athletes to keep athletes safe.”CBS will broadcast the full interview with Raisman on Sunday night.“I’m really upset,” Raisman says. “[W]hen I see these young girls that come up to me, and they ask for pictures or autographs, whatever it is, I just — I can’t — every time I look at them, every time I see them smiling, I just think — I just want to create change so that they never, ever have to go through this.”Copyright 2017 NPR.

The researchers were studying pharyngognathy in spiny fish—where the jaw changes over time to allow bones in the throat to grind down hard shells for digestion—to discover whether such an evolutionary adaption always works out, because the downside of it is a smaller gape, which means feasting on smaller fish. They noted that most such species live in shallow marine environments alongside other species that do not have the grinding capability. The exception was cichlids, which live in tropical freshwater places, such as lakes.Overall, the researchers found that pharyngognathy generally led to fish that evolved into niches that favored hard-shelled fish faster than did other fish, and that may have contributed to the decline of such fish species in Lake Victoria. The Nile perch, a non-pharyngognathous fish was introduced into the lake back in the 1950s and since that time cichlid numbers have been dropping dramatically. Initially it was assumed that the decline was due to the perch eating or killing the various cichlid species, but now, the researchers have shown that it was most likely due to them being out-competed—they compared the feeding performance of Nile perch against cichlids and discovered that the gape of the perch was double that of the cichlids, and that the cichlids also took much longer to digest prey. Taken together, the physical differences have clearly put the cichlids at a serious disadvantage, allowing the perch to thrive while the cichlids have been essentially starving to death. Thus, the specialization that came about due to the evolutionary adaption meant to allow them to eat a broader range of fish, in the end led to far less diversification in at least one closed ecosystem.

D. McGee et al. A pharyngeal jaw evolutionary innovation facilitated extinction in Lake Victoria cichlids, Science (2015). DOI: 10.1126/science.aab0800ABSTRACTEvolutionary innovations, traits that give species access to previously unoccupied niches, may promote speciation and adaptive radiation. Here, we show that such innovations can also result in competitive inferiority and extinction. We present evidence that the modified pharyngeal jaws of cichlid fishes and several marine fish lineages, a classic example of evolutionary innovation, are not universally beneficial. A large-scale analysis of dietary evolution across marine fish lineages reveals that the innovation compromises access to energy-rich predator niches. We show that this competitive inferiority shaped the adaptive radiation of cichlids in Lake Tanganyika and played a pivotal and previously unrecognized role in the mass extinction of cichlid fishes in Lake Victoria after Nile perch invasion.Press release (Phys.org)—A small team of researchers with members from the U.S. and Switzerland has found an example of a fish that did not always benefit in the end from an evolutionary change. In their paper published in the journal Science, the team describes their study of cichlid fish species in Lake Victoria and other places, and the changes that led to their downfall in one ecosystem.
