Having a video chat with five or six friends is pretty cool, but earning money from a Google Hangout? That’s awesome, and now you can do it with Helpouts.Helpouts is yet another way for Google to provide web users that are in need of help with assistance — because, yes, there are times when watching a YouTube video or seven and scrolling through pages of search results just doesn’t yield the solution to your problems.Helpouts lets anyone (for now, anyone with an invite code) set up shop online. Payments are made using Google Wallet, and Google will take a 20% cut.There are, of course, restrictions on the types of services you can provide. Things like private cooking lessons, language coaching, and bike repair? All fine. Private sex shows and one-on-one gambling? Not so much.“Dangerous” content is also not allowed, so you probably can’t use Helpouts to teach people how to construct a full-size tiger pit in their backyard, either.Clues about the arrival of Helpouts first surfaced last month, and it looks like Google has big plans for the service. Helpouts aren’t just about letting people like you or me walk someone through upgrading the RAM on their laptop. Google has corporate aspirations as well.Big companies that want a new way to reach out to customers may want to get in on the action, too. Leaked screenshots revealed a slew of Helpouts connected to a Sears Blue Crew account that helps shoppers get acquainted with their new appliances.Once it’s deemed ready for the general public, Helpouts will let users browse offerings by category or search for them — just like you would apps in Google Play or extensions in the Chrome Web Store.If you’re interested in getting an early look, just head on over to Helpouts and request an invite code.

Waste management organisation Helistrat has been accredited as a living wage employer by the Living Wage foundation.The Portsmouth-based organisation, which employs 55 members of staff, has committed to paying all employees at least the voluntary living wage rate of £8.25 an hour.The living wage is calculated according to the cost of living in the UK. It is higher than the government’s £7.20 an hour national living wage rate, which is mandatory for those over 25.Harvey Laud, chief executive officer at Helistrat, said: “We firmly believe we have a responsibility to ensure that all our employees have the opportunity to provide for themselves and enjoy a certain quality of life.“We also realise that this quality of life directly impacts on the attitude of our team and the quality of their work. Becoming a living wage employer is not only the right thing to do morally, it also makes sounds business sense.”
As it preps for the September launch of Manhattan magazine, Modern Luxury Media has acquired luxury lifestyle e-zine Juli B, bringing a 700,000-name email list of readers in fourteen cities with it. Terms of the deal were not disclosed. Juli B. delivers approximately 60 million email impressions per year, according to Modern Luxury CEO Michael Kong, as each edition is bi-weekly. “Many city magazines offer ‘email blasts’ to their subscribers that don’t even top 5,000 recipients,” Kong wrote to FOLIO: in an email. “With Juli B., we’ve got real scale and should be right on the radar screen of big national advertisers as well as smaller regional ones.” Modern Luxury will publish magazines in thirteen of Juli B.’s fourteen markets once it launches Manhattan, which will be distributed directly to 60,000 New York metropolitan area homes. The acquisition is particularly timely, according to the company, because of Juli B.’s “New York roots and the fact that the New York edition was the first and remains the biggest,” with approximately 108,000 of its readers located there. According to Kong, Manhattan surpassed its first issue ad revenue goal of $1 million several months ago. The magazine is set to launch with about 240 pages, 60 percent of which will be editorial. The acquisition of Juli B. is a first move in a series of planned digital initiatives, according to the company. Modern Luxury will announce another “major launch” in the coming weeks, Kong wrote.
Warren: The popularity of running is really taking off with women in particular. Women now account for the majority of entrants in competitive races, clocking in at 57 percent, according to RunningUSA. That’s millions of women, and I want to reach all of them! Warren: I would love to start a podcast and explore the possibility of live events. I think the best way for a brand to grow and evolve is to foster an ongoing conversation with its audience. Building a strong and engaged community of readers helps to drive the brand forward and inform its content choices, and this is a core focus for me in the next year. Warren: Our biggest challenge is the same one that every media company faces: finding the best way to connect with our audience. The constantly evolving digital landscape means publishers have to remain vigilant about new technologies and agile about responding to how consumers want to receive content. Warren: Jessie has built a phenomenal brand, and I want to carry on the work that she has done by increasing brand awareness for readers as well as for advertisers and content partners. My experience customizing and localizing content across multiple platforms for various publishing and brand partnerships and my role as a brand spokesperson will be beneficial in achieving these goals. Last month, Competitor Group tapped Lonely Planet managing editor Rebecca Warren to do just that. Folio: sat down with Warren to learn a little more about her background and plans for the title going forward. With America in the midst of a “running boom” — 17 million people ran a race in the U.S. last year, 57 percent of them females — suffice it to say that her successor has some big sneakers to fill. Folio: What do you see as some of your biggest growth opportunities for the brand? Over her seven-year tenure as editor-in-chief of Women’s Running — prior to being promoted, earlier this year, to VP of Media for parent company Competitor Group Inc. — Jessica Sebor garnered deserved applause for repositioning the monthly title as not just a fitness magazine, but an advocate for inclusion, empowerment, and positivity. Covers that once almost exclusively featured models jogging in sports bras and taglines teasing 24-hour diets and shortcuts to flat abs have given way to women of all body types, who encourage readers with messages like “Love yourself,” “Dream big,” and “Feel great.” In the past year alone, Women’s Running cover stars have included a wheelchair track and field star, a transgender woman, and a runner wearing a hijab. Folio: What about some challenges? Sebor’s impact has been felt on the business side too, where digital traffic has more then doubled in the last two years to over one million monthly visitors, while print circulation holds steady at around 45,000 copies per issue. Warren: Yes, we have a strong base of readers who subscribe to the print magazine and that remains a priority for me. Industry-wide, the dwell time with a print article is much greater than with a digital one, and it also offers a chance to have a focused, tactile interaction with the reader. The value of being able to engage with an article without a text message or alert popping up during your reading time can’t be overstated. Increasing our presence at races, through partnerships and brand ambassadors, is one way to do that. I also want to hone our social media strategy to give people a consistent and focused brand message across all of our content channels. We have a website redesign in the works as well, and my focus will be bringing a cohesive look and message across all of our content hubs. I’d also like to explore the possibility of retail partnerships and direct-to-consumer services. The fact that running is a low-barrier, widely accessible sport was also appealing. There is a broad audience available for women-specific running content, and that is an exciting opportunity. Rebecca Warren: I love what the brand stands for: inspiring and empowering women to live healthy, fulfilled lives. Women’s Running offers readers a holistic approach to wellness, focusing on running as a gateway to healthy living, by promoting positive body images, balanced nutrition, and practical and achievable fitness goals. Folio: Obviously the brand is seeing a lot of growth on the digital and social media side. Do you expect the print magazine to remain a priority going forward? Folio: Any other opportunities for expanding the WR brand? Rebecca Warren Folio: What first attracted you to the editor-in-chief role at Women’s Running? Folio: What do you bring to the position that will help you pick up where Jessie [Sebor] left off?

“A family that ‘cooks’ together, stays together” is the mantra that pushed Chef Shagun Mehra to pursue a career in food. India Food Network spoke to the talented chef and wine connoisseur about her food philosophy, inspiration and how travel has changed her perspective towards food in this interview.Do you have any fond food memory from your childhood?I remember in the summer we used to churn our own fresh Alphonso ice-cream. Each member in the family would take turns in churning the ice-cream. This was the traditional way of churning cream and mangoes into ice-cream. I am salivating at the thought of it!When was the first time you realized you want to pursue a career in food?When I was about 15, the chef at our family hotel had just completed his culinary training in Italy. Once back, he started teaching me some of the most traditional Italian recipes. This got me very excited and I wanted to study culinary arts and explore the world of gastronomy.How did the culinary school help you hone your skills as a chef?It gave me the technical know-how and insight on various cooking methods. It formed the base for me to understand different types of chopping techniques and also creating complex dishes. This enabled me to explore the culinary world and build on it using the academic and technical base that the school offered me.What is your food philosophy?I believe in the richness of local produce and traditional recipes and cooking techniques. I think India is a diverse and expansive nation and there is so much to discover in each state and within each state, there are nuances of different cuisine styles.IBT does not endorse any of the above content.
By Sean Yoes, Baltimore AFRO Editor firstname.lastname@example.orgAs we reflect on the legacy of Dr. Martin Luther King, Jr., almost 50 years after his murder on April 4, 1968, it is impossible to consider King without examining his two most famous speeches; “I Have a Dream,” delivered during the March on Washington in 1963 and, “I’ve Been To the Mountaintop,” the speech he gave the day before his assassination in Memphis, Tennessee.But, these are not just King’s most famous speeches, they are two of the most important speeches in American history. The mythic climaxes of each speech envision the elusive promise of freedom, justice and equality for all Americans.“I just want to do God’s will. And He’s allowed me to go up to the mountain. And I’ve looked over. And I’ve seen the Promised Land. I may not get there with you. But I want you to know tonight that we as a people will get to the Promised Land!” King said at the end of the Mountaintop speech in 1968.Sean Yoes (Courtesy Photo)“And when we allow freedom to ring, when we let it ring from every village and every hamlet, from every state and every city, we will be able to speed up that day when all of God’s children, Black men and White men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing in the words of the old Negro spiritual, ’Free at last. Free at last. Thank God Almighty, we are free at last,’ proclaimed King at the end of the Dream speech.So many had such great expectations for America, Black Americans specifically following the civil rights victories of the 1950s and 1960s. And for those who came of age during those turbulent, transcendent decades and then lived to see the ascension of Barack Obama, the first Black President of the United States, many believed he was the partial manifestation, or at least evidence of the lucidity of King’s dream and his view from the mountaintop.The substance and significance of Obama’s presidency may be debated for centuries. However, there is little debate the 44th President altered the trajectory of America like no other president had before him.Yet, after eight years of Obama, almost 3,000 days of the beautiful, Black Obama family occupying the White House built by slaves, the remnant of King’s ethereal dream seems to be morphing into a Black American nightmare, right before our eyes in the form of Donald J. Trump.Because, 50 years after King’s death, the vast majority of Black America finds itself in a peculiar and precarious space; enduring the volatile reign of the most unqualified, lazy, larcenous, lying, willfully ignorant, and therefore dangerous, man ever to occupy the White House.From his descension of the escalator of Trump Tower June 16, 2016, where he branded Mexicans as “rapists and murderers,” to his ascension to 1600 Pennsylvania Ave., the former reality television star has pushed a White nationalist agenda, overtly and covertly. He is arguably the most openly anti-Black U.S. President since Woodrow Wilson, who proclaimed the Ku Klux Klan propaganda film, “Birth of a Nation,” was “like writing history with lightning.”Where millions may view the fictional kingdom of Wakanda as inspirational and aspirational, Trump only sees a sh*thole fantasy.What would King have thought if he had witnessed Barack Obama orchestrate the orderly transfer of the power of the presidency to Trump, the man who orchestrated the racist lie of “birtherism?” Would he still believe in the vibrancy of his dream, or would he adhere to Langston Hughes’ “A Dream Deferred?”King made famous a quote by the abolitionist and Unitarian minister Theodore Parker. “The arc of the moral universe is long, but it bends towards justice.”For many Black Americans, the arc has become longer in the age of Trump and the bend toward justice less discernible.Sean Yoes is the Baltimore editor of the AFRO and host and executive producer of the AFRO First Edition video podcast, which airs Monday and Friday on the AFRO’s Facebook page.
By The Associated PressThousands of people on May 9 attended the funeral of Mozambican rebel and opposition leader Afonso Dhlakama, with the country’s president and Dhlakama’s successor pledging to forge ahead with peace talks.Dhlakama died at age 65 last week in his rural hideout in central Mozambique, where he had run a renewed military campaign against the southern African nation’s government after pulling out of a 1992 peace accord that ended 16 years of civil war that killed up to 1 million people.Family members of Mozambique’s opposition leader, Alfonso Dhlakama react during his state funeral in Beira about 700 kilometres south of the capital Maputo. Dhlakama, who led a rebel group during the devastating civil war that ended in 1992 died on May 3. He was 65. (AP Photo/Tsvangirayi Mukwazhi)His death came not long after he had renewed negotiations with the government.President Filipe Nyusi said those talks should continue.“I want to make it clear that I will carry on with the work that we began, the peace and strengthening of our democracy,” Nyusi said at the funeral in the port city of Beira.Dhlakama, who turned the Mozambique National Resistance, or Renamo, from a rebel group into a competitive political party after the 1992 peace deal, had demanded the decentralization of power as a condition to lay down arms. His group, which never fully disarmed, was repeatedly defeated in elections and alleged fraud.Renamo’s interim leader, Ossufo Momade, repeated the demand for more autonomy on Wednesday but committed the movement to negotiations, saying discussions also should focus on integrating Renamo’s fighters into the national army.Nyusi said he accepted the need to finalize the two demands.“I confirm my availability for the process,” the president said, adding that the fighters should disarm and join the national army.In March, Nyusi proposed constitutional changes to redistribute power to the provinces as part of peace efforts.Renamo’s interim leader also alleged that Dhlakama had died in the bush because of the military’s attempts on his life. The Portuguese news agency Lusa has reported that Dhlakama was ill prior to his death, citing an unnamed Renamo official. Nyusi has said he had hoped to help transfer Dhlakama out of the impoverished country for medical treatment, but it was too lateDhlakama’s supporters, some wearing T-shirts with his picture, lined up on Wednesday to view the body of a man loved by some and hated by others for his role in the civil war. Dozens of people climbed trees, while others followed the proceedings from the balconies of nearby apartments.The coffin was draped in the national flag while uniformed soldiers – once the main targets of rebel attacks – stood guard.Speakers described Dhlakama as a visionary, a democrat and a negotiator.“He was a man of the people. He died fighting for the freedom of the people,” Sarah Zhuwawo, who said she was a relative, told The Associated Press.Others were less charitable.“He was a bandit. He was a dangerous man, that one. He wanted this country to collapse,” said Lucas Chikweya, who was selling boiled eggs on the street.In the city of Mutare in neighboring Zimbabwe, some criticized Dhlakama for sending his fighters across the border to attack innocent villagers in the 1980s.Hordes of Mozambicans fled into Zimbabwe and neighboring Malawi as refugees during the fighting.Between 2013 and 2016, Renamo resumed low-intensity sporadic attacks on Mozambican police, the military and civilians after Dhlakama left his Beira residence for rural Gorongosa, citing renewed attacks on him by the government.However, tensions eased in 2017 as Dhlakama met Nyusi in Gorongosa to discuss differences between the two sides.“What matters most is that he was working toward peace at the end. It is important that negotiations are completed before next year’s elections,” said Zimbabwean opposition politician Chris Sibindi, who attended the funeral. Mozambique is set to hold presidential, legislative and provincial elections in October 2019.Dhlakama will be buried Thursday in his home village.

Meanwhile, researchers at Arizona State University found that magnetic fields frozen into some meteorite grains were telling a shocking tale of the birth of the solar system. They suggest that shock waves moving through the material surrounding the early sun had a major impact on how the solar system was formed.

(Phys.org)—Polycyclic aromatic hydrocarbons, such as graphene, have several potential uses as its π-conjugated structure lends itself to high stability and conductivity. Researchers are interested in exploring polycyclic aromatic hydrocarbons with boron and nitrogen atoms in an effort to explore the functionality and potential uses for polycyclic aromatic hydrocarbons. Journal information: Nature Chemistry Amino acids formed from the single-electron activation of carbon dioxide One polyatomic six-member ring that has not been isolated and studied is 1,3-dioxa-5-aza-2,4,6-triborinane, or DATB. DATB has a core B3NO2 ring that evidences some aromatic character. Hidetoshi Noda, Makoto Furutachi, Yasuko Asada, Masakatsu Shibasaki and Naoya Kumagai of the Institute of Microbial Chemistry in Tokyo (Bikaken) isolated and analyzed DATB using an m-terphenyl template. They demonstrated its ability to catalyze the direct coupling of several carboxylic acids with a variety of amines. Their DATB catalyst is thermally stable, structurally planar, and does not undergo hydrolysis. Their work appears in Nature Chemistry.The m-terphenyl template came out of the necessity to combine the B-N-B fragment to the O-B-O fragment to make the 1,2-dioxa-5-aza-2,4,6-triborinane ring. Using a stepwise synthesis, the first compound they made had the m-terphenyl template attached to the B-N-B portion of the DATB and a phenyl group attached to the boron of the O-B-O portion. The other compound that resulted from their initial syntheses had another m-terphenyl attached to the boron in the O-B-O portion of DATB instead of phenyl.The presence of DATB was confirmed with multinuclear NMR, mass spectrometry, and single-crystal x-ray diffraction. Notably, the DATB portion is planar and it exhibited offset face-to-face pi stacking. Additionally, it displayed slight aromaticity based on bond length and showed resistance toward hydrolytic cleavage.The next step was to determine if the DATB derivatives were able to catalyze amide bond formation. Boron has an affinity for amines, making this compound a possible option for catalyzing the direct coupling of amines and carboxylic acids. Noda et al. tested a variety of carboxylic acids because one of the major setbacks with amine and carboxylic acid coupling is that current methods are not generalizable for a variety of carboxylic acids, particularly bulky carboxylic acids. They tested a range of acids and amines whose coupling reactions were successfully catalyzed using DATB. They found that their DATB derivative successfully catalyzed the amide bond formation for sterically bulky aliphatic and aromatic carboxylic acids. They also found that indole-containing substrates did not require a protecting group. And, their method worked with benzoic acid and primary amines, α-branched amines, cyclic secondary amines. Using higher temperatures, they successfully coupled α-tertiary amines and acyclic secondary amines to benzoic acid. Additionally, they showed that the stereochemistry of α-chiral carboxylic acids and α-chiral amines were maintained.Their DATB derivative also worked well in the presence of various functional groups showing that the catalyst displayed good selectivity. Additionally, Noda et al. tested the catalyst’s ability to make peptide bonds with amino acids and biologically relevant amines by coupling Bz-Val-OH with H-Leu-NH2.This catalyst is remarkably versatile compared to other catalysts used for amine-carboxylic acid coupling. The authors contend that this is due to the distinct mechanism in which the three Lewis acid sites on the DATB core are used to bind the carboxylic acid and the amine countering the entropy cost in forming the bond.

Unique physicochemical and catalytic properties dictated by the B3NO2 ring system, Nature Chemistry (2017). DOI: 10.1038/nchem.2708AbstractThe expansion of molecular diversity beyond what nature can produce is a fundamental objective in chemical sciences. Despite the rich chemistry of boron-containing heterocycles, the 1,3-dioxa-5-aza-2,4,6-triborinane (DATB) ring system, which is characterized by a six-membered B3NO2 core, remains elusive. Here, we report the synthesis of m-terphenyl-templated DATB derivatives, displaying high stability and peculiar Lewis acidity arising from the three suitably arranged boron atoms. We identify a particular utility for DATB in the dehydrative amidation of carboxylic acids and amines, a reaction of high academic and industrial importance. The three boron sites are proposed to engage in substrate assembly, lowering the entropic cost of the transition state, in contrast with the operative mechanism of previously reported catalysts and amide coupling reagents. The distinct mechanistic pathway dictated by the DATB core will advance not only such amidations, but also other reactions driven by multisite activation. Explore further © 2017 Phys.org
