LOL to Heart Eyes: New Emojis Must Pass Muster

By Uponsil | 07/28/2017 | No Comments | Silicon Valley

Cheery Hi-5, a snobbish Poop and a conflicted Meh have starring roles in the animated The Emoji Movie, which imagines a world inside cellphones where emojis rebel against portraying just one emotion all their lives.

Yet the dozen or so people who select and release the tiny, ubiquitous characters globally are far removed from the glitz of Hollywood, where the Sony Pictures movie, which begins its global rollout Friday, was developed.

The humans who toil in obscurity to shape and approve new emojis are part of the Unicode Consortium, a Silicon Valley-based group of computer and software corporations and individual volunteers with backgrounds in technology, encoding and linguistics.

2,600-plus emojis

From smiley faces to thumbs up, there are now more than 2,600 emojis worldwide and, according to a July Facebook report, more than 60 million a day are sent on the No. 1 social media network alone.

The consortium approves about 50-100 new emojis every year, not counting the different skin tones for people emoji, after a rigorous application and review process, said Mark Davis, president and co-founder of the group.

The latest batch, released in June and reaching phones and other devices in coming months, include a star-struck emoji, an exploding head, a group of wizards, mermaids and a woman wearing a hijab.

Submissions from everywhere

“We get submissions from all over the world,” Davis said in an interview. “The hijab emoji came from a Saudi Arabian young woman who is living in Germany who made a very compelling proposal. I’m looking forward to the exploding head — I think that’s going to be very popular.

“People need to make a case as to why they think their emoji is going to be frequently used, how it breaks new ground, how it is different from other emojis that have already been encoded.”

Logos, brands and emojis tied to specific companies are not accepted. “We also don’t accept specific people. We did encode a cowboy but we wouldn’t encode John Wayne,” Davis said.

Some concepts just do not translate as emoji.

LOL emoji most popular

“Anything that needs a lot of detail to explain or understand is trouble. It’s also hard to make an emoji for something abstract — like good governance, or a responsible president,” Davis said.

Davis said there are 2,666 emojis worldwide. The LOL emoji with tears of laughter is the most popular, according to a July Facebook survey of its 2 billion monthly users, followed by the heart eyes emoji. Italians and Spaniards favor the kissing emoji.

The consortium played no part in the making of The Emoji Movie, Davis said, because all of its work is open-source, available to all, and no permission was needed.

Nevertheless, he never imagined that the computer-generated punctuation marks that originated in Japan in the 1980s would become Hollywood stars.

“That’s something that never really crossed our minds,” Davis said.

AIDS Burdens Zimbabwe’s Elderly With Orphans, Illness

By Uponsci | 07/28/2017 | No Comments | Science

Jabulani Zilawe lost all 11 of his children to AIDS. Now he is the only one left to care for their orphans.

“This has become my life — with my grandchildren. All their parents died. AIDS killed them. I had 11 children, six of them were girls who had moved to South Africa to seek better life, but they all came back dead — one after the other,” Zilawe told the Thompson Reuters Foundation as he surveyed his small grandchildren scrambling around him.

Zilawe lives in a dilapidated homestead outside Norton, a town 40 kilometers from Harare, the Zimbabwean capital.

His bedroom is a thatched mud hut that sits near 12 mounds marking the remains of his wife and children.

“My sons, who became illegal gold miners, also suffered from AIDS before they died. You can see the graves here; the additional one belongs to my wife, who also died some two years ago, leaving me to look after our orphaned grandchildren,” said Zilawe, 76.

Nearby, some of his grandchildren wrestled over a pot of leftover porridge. None is in school; instead, like their grandfather, each child passes the day at the homestead, idling and seeking a spot to bask in the sunshine.

Some of the little ones fall ill — regularly, said Zilawe, who didn’t know whether any carried the virus that had killed their parents.

“I don’t know anything about my grandchildren’s HIV status; maybe they have the disease or maybe not,” he said.

Ailing caregivers

His life is tough. Yet many other Zimbabweans in Zilawe’s age bracket are not just caregivers but are also coping with AIDS diagnoses of their own.

“It’s sad. It’s worrying when you look at the rate of HIV/AIDS amongst aged persons here. The percentage of elderly persons aged 60 years and above living with HIV is around 15.3 percent,” said Marck Chikanza, national coordinator of the National Age Network of Zimbabwe (NANZ), an organization that caters to older people’s needs.

NANZ said more than 115,000 older people are living with HIV and AIDS in Zimbabwe, one in 10 of the 1.2 million Zimbaweans who the United Nations says are living with HIV/AIDS.

“There has been a decline in the rate of people living with HIV across all age groups except in the 50+ age group, where there has been a rise from 13.8 percent to around 14.3 percent,” said Tadiwa Pfupa-Nyatanga of the NAC organization, which coordinates the government’s response to HIV/AIDS.

According to 2016 official statistics, about 185,000 AIDS-orphaned Zimbabwean children are living under the guardianship of their grandparents — people like Zilawe, who struggle to cope.

“Most aged persons here hardly have the capacity to produce or buy food on their own. And most of the orphaned kids they look after are far too young to be working to produce food for their families. And the burden, at the end of the day, rests with the grandparents — who, in a true sense, are also dependents,” Anatalia Mabeza, who chairs an HIV/AIDS support group in Norton, told the Thomson Reuters Foundation..

Some orphaned children say their grandparents offer little or no medical help for the health problems they inherited.

“I was openly told by my mother before she died that I was born with the HIV/AIDS condition, but now as I live with my grandmother, who is in her 60s, she has never bothered to monitor my condition,” said Lillian Muranda, 14, who lives in Caledonia informal settlement, 25 kilometers east of Harare.

‘I was bewitched’

“She tells me I was bewitched, but I’m always ill and absent from school most of the time,” Muranda told the Thomson Reuters Foundation.

As Muranda delved deeper into the bewitching story, her grandmother, Agnes Muranda, stepped in sharply to intervene: “Why do you bother her? You newsmen are very bad. You want to rule out witchcraft from my granddaughter’s illness. Leave us.”

Superstitious beliefs like this hinder government efforts to combat AIDS, and even if a grandparent has good information and plenty of intent, it doesn’t mean that help will follow.

“We have no means to support our AIDS-orphaned grandchildren besides the treatment drugs they receive from government health care centers. What we can only do is to make sure they take their medication. Remember, we are also victims of a failing economy and there are also many amongst aged persons who are living with HIV,” said Jonathan Mandaza, who chairs the Zimbabwe Older Persons’ Organization.

As Zilawe sees it, he is shunned as an aging irrelevance yet is left to pick up the pieces of his children’s lost lives.

“As older persons, we are not consulted on HIV and AIDS issues, yet there is also a strong misconception that sex matters don’t concern us. As such, access points for condoms and other HIV/AIDS services only favor younger people, leaving us out,” said Zilawe.

More Cyber Attacks, More Job Security for Hackers

By Uponsil | 07/28/2017 | No Comments | Silicon Valley

The surge in far-flung and destructive cyber attacks is not good for national security, but for an increasing number of hackers and researchers, it is great for job security.

The new reality is on display in Las Vegas this week at the annual Black Hat and Def Con security conferences, which now have a booming side business in recruiting.

“Hosting big parties has enabled us to meet more talent in the community, helping fill key positions and also retain great people,” said Jen Ellis, a vice president with cybersecurity firm Rapid7 Inc., which filled the hip Hakkasan nightclub Wednesday at one of the week’s most popular parties.

More tech, more jobs

Twenty or even 10 years ago, career options for technology tinkerers were mostly limited to security firms, handfuls of jobs inside mainstream companies, and in government agencies.

But as tech has taken over the world, the opportunities in the security field have exploded.

Whole industries that used to have little to do with technology now need protection, including automobiles, medical devices and the ever-expanding Internet of Things, from thermostats and fish tanks to home security devices.

More insurance companies now cover breaches, with premiums reduced for strong security practices. And lawyers are making sure that cloud providers are held responsible if a customer’s data is stolen from them and otherwise pushing to hold tech companies liable for problems, meaning they need security experts too.

1.8 million skilled workers needed

The nonprofit Center for Cyber Safety and Education last month predicted a global shortage of 1.8 million skilled security workers in 2022. The group, which credentials security professionals, said that a third of hiring managers plan to boost their security teams by at least 15 percent.

For hackers who prefer to pick things apart rather than stand guard over them, an enormous number of companies now offer “bug bounties,” or formal rewards, for warnings about vulnerabilities that leave them exposed to criminals or spies.

New ways to make money

One of the outside firms that handle such programs, HackerOne, said it has paid out $18.8 million since 2014 to fix 50,140 bugs, with about half of that work done in the past year.

Mark Litchfield made it into the firm’s “Hacker Hall of Fame” last year by being the first to pull in more than $500,000 in bounties through the platform, well more than he earned at his last full-time security job, at consulting firm NCC Group.

In the old days, “The only payout was publicity, free press,” Litchfield said. “That was the payoff then. The payoff now is literally to be paid in dollars.”

There are other emerging ways to make money too. Justine Bone’s medical hacking firm, MedSec, took the unprecedented step last year of openly teaming with an investor who was selling shares short, betting that they would lose value.

It was acrimonious, but St Jude Medical ultimately fixed its pacemaker monitors, which could have been hacked, and Bone predicted others will try the same path.

“Us cyber security nerds have spent most of our careers trying to make the world a better place by engaging with companies, finding bugs which companies may or may not repair,” Bone said.

“If we can take our expertise out to customers, media, regulators, nonprofits and think tanks and out to the financial sector, the investors and analysts, we start to help companies understand in terms of their external environment.”

Chris Wysopal, co-founder of code auditor Veracode, bought in April by CA Technologies, said that he was initially skeptical of the MedSec approach but came around to it, in part because it worked. He appeared at Black Hat with Bone.

“Many have written that the software and hardware market is dysfunctional, a lemon market, because buyers don’t know how insecure the products they purchase are,” Wysopal said in an interview. “I’d like to see someone fixing this broken market. Profiting off of that fix seems like the best approach for a capitalism-based economy.”

New Surgical Glue Inspired by Slug Slime

By Uponsci | 07/28/2017 | No Comments | Science

Scientists have developed an experimental surgical glue inspired by the mucus secreted by slugs that could offer an alternative to sutures and staples for closing wounds.

While some medical glues already exist, they often adhere weakly, are not particularly flexible and frequently cannot be used in very wet conditions.

To get around those problems, a group of scientists from Harvard and other research centers decided to learn from slugs, which — as well as making slime to glide on — can produce extremely adhesive mucus as a defense mechanism.

The slugs’ trick is to generate a substance that not only forms strong bonds on wet surfaces but also has a matrix that dissipates energy at the point of adhesion, making it highly flexible.

Strong, nontoxic

The man-made version of this tough adhesive is based on the same principles and in a series of experiments reported in the journal Science on Thursday it was shown to adhere strongly to pig skin, cartilage, tissue and organs. It also proved nontoxic to human cells.

In one test, the new glue was used to close a wound in a blood-covered pig’s heart and successfully maintained a leak-free seal after the heart was inflated and deflated tens of thousands of times.

In another case it was applied to a laceration in a rat’s liver and performed just as well as a hemostat, a surgical tool often used in operations to control bleeding.

“There are a variety of potential uses and in some settings this could replace sutures and staples, which can cause damage and be difficult to place in certain situations,” said researcher David Mooney, professor of bioengineering at Harvard.

Mussel-inspired glue

Mooney and colleagues envisage the new adhesive will be made in sheets and cut to size, although they have also developed an injected version for closing deep wounds. The injection would be hardened using ultraviolet light, like dental fillings.

It is not the first time that scientists have taken inspiration from nature to devise a better medical adhesive.

Four years ago, another research group developed a glue inspired by the underwater sticking properties of mussels, but Mooney thinks slugs win hands-down in terms of stickiness and flexibility.

The scientists are applying for patents, although it will require a commercial company to then license the technology and take it into the next phase of human clinical trials.

Warming to Worsen Dead Zones, Algae Blooms Choking US Waterways

By Uponsci | 07/28/2017 | No Comments | Science

Projected increases in rain from global warming could further choke U.S. waterways with fertilizer runoff that trigger dead zones and massive algae blooms, a new study said.

If greenhouse gas emissions keep rising, more and heavier rain will increase nitrogen flowing into lakes, rivers and bays by about 19 percent by the end of the century, according to a study in Thursday’s journal Science.

While that may not sound like much, many coastal areas are already heavily loaded with nitrogen. Researchers calculated that an extra 860,000 tons of nitrogen yearly will wash into American waterways by century’s end.

The nutrients create low-oxygen dead zones and harmful blooms of algae in the Gulf of Mexico, Great Lakes, Pacific Northwest and Atlantic coast.

“Many of these coastal areas are already suffering year-in, year-out from these dead zones and algal blooms,” said one of the researchers, Anna Michalak, an ecologist at the Carnegie Institution for Science at Stanford University. “And climate change will make it all worse.”

When waterways are overloaded with nutrients, algae growth can run amok, creating dead zones. Algae can also choke waterways with “green mats of goop on top of the water” that are giant floating blooms, Michalak said.

The blooms often have toxins that can pollute drinking water. In 2014, a bloom on Lake Erie fouled tap water for half a million people in Toledo, Ohio, for more than two days.

The study, which is based on computer simulations, found the Northeast and Midwest will be hit hardest by the increase in nitrogen runoff. Most of the excess nitrogen from fertilizer use and the burning of coal, oil and gas would flow into the Mississippi River system and into the Gulf of Mexico, one of the largest dead zones on Earth, researchers said.

“The results are incredibly interesting and compelling,” said Samantha Joye, a University of Georgia marine sciences professor who wasn’t part of the team.

Google Hopes to Train 10M Africans in Online Skills, CEO Says

By Uponsil | 07/28/2017 | No Comments | Silicon Valley

Alphabet’s Google aims to train 10 million people in Africa in online skills over the next five years in an effort to make them more employable, its chief executive said Thursday.

The U.S. technology giant also hopes to train 100,000 software developers in Nigeria, Kenya and South Africa, a company spokeswoman said.

Google’s pledge marked an expansion of an initiative it launched in April 2016 to train young Africans in digital skills. It announced in March that it had reached its initial target of training 1 million people.

The company is “committing to prepare another 10 million people for jobs of the future in the next five years,” Google Chief Executive Sundar Pichai told a company conference in Nigeria’s commercial capital, Lagos.

Google said it would offer a combination of in-person and online training. Google has said on its blog that it carries out the training in languages including Swahili, Hausa and Zulu and tries to ensure that at least 40 percent of people trained are women. It did not say how much the program cost.

Africa, with its rapid population growth, falling data costs and heavy adoption of mobile phones, having largely leapfrogged personal computer use, is tempting for tech companies.

Executives such as Alibaba Group Holding Ltd.’s Chairman Jack Ma have also recently toured parts of the continent.

Basic phones, less surfing

But countries like Nigeria, Kenya and South Africa, which Google said it would initially target for its mobile developer training, may not offer as much opportunity as the likes of China and India for tech firms.

Yawning wealth gaps mean that much of the population in places like Nigeria has little disposable income, while mobile adoption tends to favor more basic phone models. Combined with bad telecommunications infrastructure, that can mean slower and less internet surfing, which tech firms rely on to make money.

Google also announced plans to provide more than $3 million in equity-free funding, mentorship and working space access to more than 60 African startups over three years.

In addition, YouTube will roll out a new app, YouTube Go, aimed at improving video streaming over slow networks, said Johanna Wright, vice president of YouTube.

YouTube Go is being tested in Nigeria as of June, and the trial version of the app will be offered globally later this year, she said.
