Police in a Washington suburb are searching for the killer of Bettie Jenifer, wife of popular Ghanaian actor Chris Attoh.

Police say Jenifer was shot and killed Friday afternoon in Greenbelt, Maryland, as she left the office building where she worked.

Witnesses say Jenifer saw a man with a gun standing in the parking lot. As she tried to run away, the gunman chased her, shooting her twice.

Police say they believe she was the victim of a targeted killing and that the gunman is at large. 

Attoh was in Los Angeles working on a film and immediately flew to Maryland.

Reports say investigators are studying Attoh’s social media posts after he deleted all photographs of him and Jenifer together on his websites — leading to speculation in Ghana that the couple was splitting up.

Attoh and Jenifer were married for just seven months.

South Africa, which has the largest population of rhinos in the world, has been the country hit hardest by poaching. Between 2007 and 2015, there was a 9,000% increase in poaching there, reaching a high of 1,215 animals in 2014. While numbers have been declining since then, poaching remains a problem. But as Faith Lapidus reports, technology is helping turn one game reserve into a high-tech fortress.

Officials in Pakistan and the United Nations are investigating causes of a new outbreak of HIV infections in a southern district where 337 people have been diagnosed in less than two weeks. Officials confirmed Saturday that 270 children were among the victims, with nearly half of them under age 5. 

Local media began reporting about the epidemic two weeks ago from Larkana, a district of Sindh province, which has already experienced three outbreaks in recent years. A local doctor who treated several patients with a single needle and syringe was blamed for spreading the virus, which causes AIDS. 

The provincial government rushed teams of public health workers to the district, with an estimated population of 1.5 million, to quickly assess the situation and mobilize resources to curtail further spread of HIV. As of Friday, more than 7,500 people had been screened in the affected district and the process is continuing, officials said. 

A UNAIDS spokeswoman told VOA that international partners had joined local teams to help quickly carry out an outbreak investigation and address the acute needs of the people infected with HIV, including immediately linking them to treatment, care and support services. 

The spokeswoman, Fahmida Khan, said efforts were being made to ensure that unsafe injection and blood transfusion practices were being stopped. She also noted that there were unconfirmed reports of similar HIV outbreaks in surrounding districts. 

​Focus of problem

Sindh, with a population of nearly 48 million, accounts for 43% of an estimated 150,000 people living with HIV in Pakistan. 

U.N. officials say since 2010, there has been a 57% increase in new HIV/AIDS infections in Pakistan. They noted that among all identified HIV cases in Pakistan, 43,000 are females. 

Last year, an estimated 20,000 people were newly identified with HIV in Pakistan and 6,200 people died of AIDS, according to local and U.N. officials. 

Khan would not comment on the reasons for the high number of HIV infections among children and the potential causes of the latest outbreak in Larkana, saying “further investigations and epidemiological review is yet required and suggested.” 

Provincial authorities also have launched a high-level investigation to ascertain the veracity of the allegations against the local doctor, who already has been taken into police custody. 

Some also blame unsafe injection practices by quack doctors for contributing to the spread of HIV. Government officials estimate about 600,000 unqualified doctors are unlawfully operating in Pakistan and 270,000 of them are practicing in Sindh. 

Critics also blame lapses in Pakistan’s national health system, the low priority given to the problem, corruption, the recent abolition of the federal health ministry and the delegation of its functions to the provinces for the worsening health sector situation and the increase in HIV infections.

Nearly every country in the world has agreed upon a legally binding framework to reduce the pollution from plastic waste except for the United States, U.N. environmental officials say.

An agreement on tracking thousands of types of plastic waste emerged Friday at the end of a two-week meeting of U.N.-backed conventions on plastic waste and toxic, hazardous chemicals.

Discarded plastic clutters pristine land, floats in huge masses in oceans and rivers and entangles wildlife, sometimes with deadly results.

Rolph Payet of the United Nations Environment Program said the “historic” agreement linked to the 186-country, U.N.-supported Basel Convention means that countries will have to monitor and track the movements of plastic waste outside their borders.

The deal affects products used in a broad array of industries, such as health care, technology, aerospace, fashion, food and beverages.

“It’s sending a very strong political signal to the rest of the world — to the private sector, to the consumer market — that we need to do something,” Payet said. “Countries have decided to do something which will translate into real action on the ground.”

Countries will have to figure out their own ways of adhering to the accord, Payet said. Even the few countries that did not sign it, like the United States, could be affected by the accord when they ship plastic waste to countries that are on board with the deal.

Payet credited Norway for leading the initiative, which first was presented in September. The time from that proposal to the approval of a deal set a blistering pace by traditional U.N. standards for such an accord.

The framework “is historic in the sense that it is legally binding,” Payet said. “They (the countries) have managed to use an existing international instrument to put in place those measures.”

The agreement is likely to lead to customs agents being on the lookout for electronic waste or other types of potentially hazardous waste more than before.

“There is going to be a transparent and traceable system for the export and import of plastic waste,” Payet said.

Dementia is a rapidly growing public health problem around the world. Fifty million people suffer from dementia, and in the next 30 years, that number is expected to triple.

Researchers are looking for ways to treat or prevent dementia, and a promising clinical trial is underway in the U.S.

Dementia is not a normal part of aging, but age is a huge risk factor. Regular exercise, a healthy diet, maintaining healthy blood pressure, cholesterol, and blood sugar levels help stave off dementia as we grow older

As people around the world live longer, health agencies and researchers are looking for ways to prevent, stop or treat dementia, including Alzheimer’s disease, one of the most common types of dementia.

Promising clinical trial

David Shorr was diagnosed with Alzheimer’s at 56.He is about to undergo a new procedure that could treat early stage Alzheimer’s. He is with his doctor, Vibhor Krishna, a neurosurgeon at Ohio State Wexner Medical Center.

The procedure Shorr is about to have involves sound waves. Ultrasound waves target and open the blood-brain barrier — a protective layer that shields the brain from infections. But Krishna says the barrier also makes it hard to treat neurodegerative diseases like Alzheimer’s.

“Opening the blood-brain barrier allows us to access more of the brain tissue and be able to increase the effectiveness or bioavailability of the therapeutics,” Krishna said.

Shorr and his wife, Kim, were willing to try any new treatment that might help with his dementia. Kim describes the couple’s reaction when they received a phone call inviting Shorr to participate in a clinical trial.

“There’s this trial. Would you be interested?” she said, describing the call. “And without really knowing what it was, we said, Sure.’”

Ultrasound targets protein buildup

Shorr became one of 10 patients enrolled in the study. The trial tests MRI-guided imaging to target the part of the brain responsible for memory and cognition. Krishna explains that’s where Alzheimer’s patients have a buildup of toxic proteins called amyloid.

“Higher deposition of amyloid goes hand in hand with loss of function in Alzheimer’s disease,” he said.

Krishna says this procedure might allow a patient’s own immune system to clear some of the amyloid.

In this procedure, ultrasound wave pulses cause microscopic bubbles to expand and contract in the brain.

“The increase and decrease in size of these microbubbles mechanically opens the blood-brain barrier,” Krishna said.

The patient is awake during the procedure.

Study could help others

Opening the barrier may one day allow doctors to deliver medication straight to the site of the disease.

Kim Shorr realizes her husband might not benefit from this treatment.

“We’re hopeful it can help him, but we also know maybe it will help somebody else,” she said.

Shorr is glad to be part of a study that could help others who are in the early stages of Alzheimer’s, even if it doesn’t help him.

Billionaire Richard Branson is moving Virgin Galactic’s winged passenger rocket and more than 100 employees from California to a remote commercial launch and landing facility in southern New Mexico, bringing his space tourism dream a step closer to reality.

Branson said Friday at a news conference that Virgin Galactic’s development and testing program has advanced enough to make the move to the custom-tailored hangar and runway at the taxpayer-financed Spaceport America facility near the town of Truth or Consequences.

Virgin Galactic CEO George Whitesides said a small number of flight tests are pending. He declined to set a specific deadline for the first commercial flight.

An interior cabin for the company’s space rocket is being tested, and pilots and engineers are among the employees relocating from California to New Mexico. The move to New Mexico puts the company in the “home stretch,” Whitesides said.

The manufacturing of the space vehicles by a sister enterprise, The Spaceship Company, will remain based in the community of Mojave, California.

​Taxpayer backing

Taxpayers invested more than $200 million in Spaceport America after Branson and then-Gov. Bill Richardson, a Democrat, pitched the plan for the facility, with Virgin Galactic as the anchor tenant.

Virgin Galactic’s spaceship development has taken far longer than expected and had a major setback when the company’s first experimental craft broke apart during a 2014 test flight, killing the co-pilot.

Branson thanked New Mexico politicians and residents for their patience over the past decade. He said he believes space tourism — once aloft — is likely to bring about profound change.

“Our future success as a species rests on the planetary perspective,” Branson said. “The perspective that we know comes sharply into focus when that planet is viewed from the black sky of space.”

Branson described a vision of hotels in space and a network of spaceports allowing supersonic, transcontinental travel anywhere on earth within a few hours. He indicated, however, that building financial viability comes first.

“We need the financial impetus to be able to do all that,” he said. “If the space program is successful as I think … then the sky is the limit.”

​Gushing passenger

In February, a new version of Virgin Galactic’s winged craft SpaceShipTwo soared at three times the speed of sound to an altitude of nearly 56 miles (99 kilometers) in a test flight over Southern California, as a crew member soaked in the experience.

On Friday, that crew member, Beth Moses, recounted her voyage into weightlessness and the visual spectacle of pitch-black space and the earth below.

“Everything is silent and still and you can unstrap and float about the cabin,” she said. “Pictures do not do the view from space justice. … I will be able to see it forever.”

The company’s current spaceship doesn’t launch from the ground. It is carried under a special plane to an altitude of about 50,000 feet (15,240 meters) before detaching and igniting its rocket engine.

“Release is like freefall at an amusement park, except it keeps going,” Moses said. “And then the rocket motor lights. Before you know it, you’re supersonic.”

First commercial flight may be this year

The craft coasts to the top of its climb before gradually descending to earth, stabilized by “feathering” technology in which twin tails rotate upward to increase drag on the way to a runway landing.

Branson previously has said he would like to make his first suborbital flight this year as one of the venture’s first passengers on the 50th anniversary of the Apollo 11 moon landing on July 20. But he made no mention of timelines on Friday.

Pressed on the timeframe, Whitesides said he anticipates the first commercial flight within a year.

Three people with future space-flight reservations were in the audience.

“They’ve been patient, too,” Branson said. “Space is hard.”

Hundreds of potential customers have committed as much as $250,000 up front for rides in Virgin’s six-passenger rocket, which is about the size of an executive jet.

Virgin not alone

Other Branson’s plans have gradually advanced amid a broader surge in private investment in space technology with cost-saving innovations in reusable rockets and microsatellite technology.

Amazon tycoon Jeff Bezos announced Thursday that his space company, Blue Origin, will send a robotic spaceship to the moon with aspirations for another ship that could bring people there along the same timeframe as NASA’s proposed 2024 return. Bezos has provided no details about launch dates.

The question comes up over and over, with extremist material, hate speech, election meddling and privacy invasions. Why can’t Facebook just fix it?

It’s complicated, with reasons that include Facebook’s size, its business model and technical limitations, not to mention years of unchecked growth. Oh, and the element of human nature.

The latest revelation: Facebook is inadvertently creating celebratory videos using extremist content and auto-generating business pages for the likes of Islamic State and al-Qaida. The company says it is working on solutions and the problems are getting better. That is true, but critics say better is not good enough when mass shootings are being live-streamed and online mobs are spreading rumors that lead to deadly violence.

“They have been frustratingly slow in dealing with everything from child sexual abuse to terrorism, white supremacy, bullying, nonconsensual porn” and things like allowing advertisers to target categories such as “Jew hater,” simply because some users had listed the term as an “interest,” said Hany Farid, a digital forensics expert at the University of California, Berkeley.

As new problems crop up, Facebook’s formula has been to apologize and promise to make changes, sometimes also noting that it did not anticipate how malicious actors could so readily misuse its platform. More recently, the company has also emphasized just how much it is improving, both technically in its use of artificial intelligence to detect problems and in terms of focusing more money and effort on fixing them.

“After making heavy investments, we are detecting and removing terrorism content at a far higher success rate than even two years go,” Facebook said Wednesday in response to the revelations about the auto-generated pages. “We don’t claim to find everything, and we remain vigilant in our efforts against terrorist groups around the world.”

It has seen some success. In late 2016, CEO Mark Zuckerberg infamously dismissed as “pretty crazy” the idea that fake news on his service could have swayed the election. He later backtracked, and since then the company has reduced the amount of misinformation shared on its service, as measured by several independent studies.

Zuckerberg has also, by and large, avoided similar gaffes by conceding mistakes and delivering apologies to the public and to lawmakers.

‘Stuck with all this garbage’

But even as the company bats down one problem, others pop up. The reason for that might be baked into its DNA. And that’s not just because its business model relies on as many people as possible using it as much as possible, leaving behind personal details that can then be targeted by advertisers.

“Almost everything Facebook has designed has been designed for good people. People who are nice to each other, who have birthdays to celebrate, who have new puppies and generally like to treat others well,” said Siva Vaidhyanathan, director of the Center for Media and Citizenship at the University of Virginia. “Basically Facebook is made for a better species than ours. If it were made for golden retrievers, everything would be great.”

But if just 1% of the 2.4 billion people on Facebook want to do terrible things to others, that’s 24 million people.

“Every couple of weeks, we hear about Facebook knocking down troublesome pages, making promises about hiring more people, building AI and so on,” Vaidhyanathan said. “But at Facebook’s scale, none of that will matter. We are basically stuck with all this garbage.”

Chris Hughes, a co-founder of Facebook, called for a breakup of the social media giant in a Thursday op-ed. Vaidhyanathan also thinks strong government regulation could be the answer, such as laws that “limit companies’ ability to suck up all our data and use it to target advertising.”

“We really should be addressing the back end of Facebook,” he said. “That’s what you have to attack.”

One of the main intentions of Habiba Nowrose’s work as a Bangladeshi photographer is to draw attention to the pressure Bangladesh society puts on women to always present their “beauty” in public. Nowrose’s conceptual photography project, “Concealed,” exposes the way women lose their identity, individuality and sense of self in the Bangladesh society. The faces of her models are always fully covered, representing the stripping away, loss and erasure of the personal stories, traumas and individuality of each subject, says the 29-year-old artist.

In this photo story, we take a glimpse into the “Concealed” world of Bangladesh women through Habiba Nowrose’s lens.
