America’s first black astronaut, Air Force Maj. Robert Lawrence Jr., finally got full honors Friday on the 50th anniversary of his death.

Several hundred people gathered at Kennedy Space Center to commemorate Lawrence, who almost certainly would have gone on to fly in space had he not died in a plane crash on Dec. 8, 1967.

The crowd included NASA dignitaries, astronauts, fellow Omega Psi Phi fraternity members, schoolchildren, and relatives of Lawrence and other astronauts who have died in the line of duty.

Lawrence was part of a classified military space program in the 1960s called the Manned Orbiting Laboratory, meant to spy on the Soviet Union. He died when his F-104 Starfighter crashed at Edwards Air Force Base in California. He was 32.

Astronauts at Friday’s two-hour ceremony said Lawrence would have gone on to fly NASA’s space shuttles and that, after his death, he inspired all the African-American astronauts who followed him. 

 Like Lawrence, Robert Crippen was part of the Air Force’s program. It was canceled in 1969 without a single manned spaceflight, prompting Crippen and other astronauts to move on to NASA. Crippen was pilot of the first space shuttle flight in 1981.

With a doctoral degree in physical chemistry — a rarity among test pilots — Lawrence was “definitely on the fast track,” Crippen said. He graduated from high school at age 16 and college at 20.

“He had a great future ahead of him if he had not been lost 50 years ago today,” Crippen said.

Lawrence paved the way for Guy Bluford, who became the first African-American in space in 1983, Dr. Mae Jemison, the first African-American woman in space in 1992, and Charles Bolden Jr., a space shuttle commander who became NASA’s first black administrator in 2009. Next year, the International Space Station is getting its first African-American resident: NASA astronaut Jeanette Epps.

Another former African-American astronaut, Winston Scott, said his own shuttle rides into orbit would not have happened if not for a trailblazers like Lawrence. In tribute to Lawrence, a jazz lover, Scott and his jazz band serenaded the crowd with “Fly Me to the Moon” and other tunes.

Lawrence’s sister, Barbara, a retired educator, said he considered himself the luckiest man in the world for being able to combine the two things he loved most: chemistry and flying.

Lawrence’s name was etched into the Astronauts Memorial Foundation’s Space Mirror at Kennedy for the 30th anniversary of his death in 1997, following a long bureaucratic struggle. It took years for the Air Force to recognize Lawrence as an astronaut, given he’d never flown as high as the 1960s-required altitude of 50 miles.

The Space Mirror Memorial bears the names of two other African-Americans: Ronald McNair, who died aboard space shuttle Challenger in 1986, and Michael Anderson, who died on shuttle Columbia in 2003.

Marsalis Walton, 11, who drove from Tampa with his father, Sam, came away inspired. He dreams of becoming an astronaut.

“It feels good that everyone has a chance to do anything,” the boy said.

Rapid action prevented the spread of the deadly Marburg virus just weeks after it was first detected in Uganda, the World Health Organization reports.

The first case of the disease in the African country was confirmed October 17, when laboratory tests found the death of a 50-year-old woman was due to the Marburg virus.  

“Within 24 hours of being informed by the Ugandan health authorities in early October, WHO deployed a rapid response team to the remote mountainous area and we have financed the immediate support and scaled up the response in Uganda and Kenya,” said World Health Organization spokeswoman, Fadela Chaib. 

WHO released $623,000 from its emergency fund to finance the action.

Marburg is a highly fatal disease caused by a virus from the same family as that of Ebola. It can be transmitted from person to person by bodily fluids, and can cause bleeding, fever, vomiting, diarrhea and other symptoms. 

This was the fifth outbreak of Marburg virus in a decade, and lessons have been learned from those outbreaks, as well as from the West African Ebola epidemic that killed more than 11,000 people.

“Marburg is very infectious,” Chaib said. “It was also important to trace all the contacts of this first case and to follow them for a period of 21 days, plus 21 days just to make sure that there [are] no other cases being detected.” 

WHO reports three people died over the course of the outbreak, which affected two districts in eastern Uganda near the Kenyan border. Surveillance and contact tracing on the Kenyan side of the border by the Kenyan Ministry of Health and its partners also prevented cross-border spread of the disease, according to WHO.

Mammography has been a standard screening device for breast cancer since the mid-1970s. And the practice is credited with a 30 percent decline in death, thanks to early detection and treatment.

Now, many doctors are urging women to get a 3-D mammogram, which produces a more detailed view of the breast. But there has not been a large-scale study to determine if the technology actually provides a better outcome — until now.

Women older than 50 are advised to get a mammogram every year or two to screen for breast cancer, the second leading cause of cancer deaths among women.

​Comparing mammograms

A new study funded by the National Cancer Institute will compare traditional mammograms with the 3-D version to determine if the newer, often pricier choice really improves early detection of tumors.

“It’s a new technology that has been FDA approved,” said Dr. Tova Koenigsberg of Montefiore Health Systems in New York. “But we don’t actually have studies that know whether in a large population 3-D actually helps.”

Koenigsberg heads the project at Montefiore Einstein Center for Cancer Care, one of about 100 clinics participating in the five-year study. The clinics, spread across the United States, and a few in Canada, will soon enroll healthy women ages 45 to 74 who are planning to get a routine mammogram, including Sabitri Jaipersaud.

After a doctor found what turned out to be a benign abnormality in her breast, she became diligent about annual mammograms and felt joining the study was important.

“It immediately piqued my interest because I feel that all, all of us can benefit from this and for the future,” Jaipersaud said.

The women in the study will be randomly assigned to get either the regular mammogram or the 3-D version for five years. Most will be screened annually but post-menopausal women who don’t have certain cancer risk factors will be screened every other year.

A traditional mammogram takes an X-ray of the breast from top to bottom and side-to-side.

“In a 3-D mammogram,” Koenigsberg said, “the camera actually sweeps at an angle and allows us to see the breast at different angles and projections.”

Known pros, cons

Doctors know that there are pros and cons to 3-D mammography, said Dr. Otis Brawley, chief medical officer of the American Cancer Society.

“It might find disease that we need to find that two-dimensional does not,” Brawley said. “There’re potential cons in that it has a higher cost, higher amount of radiation, given every dose, every time a person has a test, as well as it may find a higher number of false positives.”

As for what type to choose, some insurers, including Medicare, cover the 3-D version, and a small number of states mandate coverage. Other insurers may require women to pay $50 to $100 more out of pocket.

After collecting the result of every scan, biopsy and cancer at the end of the study, researchers hope to provide certainty about how often women should get mammograms, and which women would benefit most from which type.

A Congolese fashion designer is promoting safe sex with a collection of clothes made of condoms that she hopes will help combat HIV/AIDS in the central African country.

Felicite Luwungu started making her condom line, which includes strapless evening gowns and tops, after the HIV/AIDS epidemic hit close to home.

“I have lost loved ones to HIV – that’s what inspired me to do this,” she told the Thomson Reuters Foundation by phone from the capital, Kinshasa. “The message that I hope people will apply is to be prudent.”

The number of people living with HIV/AIDS and dying from related infections in the Democratic Republic of Congo has been falling for more than a decade, according to the United Nations.

The prevalence rate of HIV, the virus that causes AIDS, is about 0.7 percent, among the lowest in southern and central Africa, UNAIDS data shows.

Luwungu, 40, displays her work in runway shows and exhibitions. When she finishes the condom collection, she plans to present it at a large fashion show next year.

The designs have shocked audiences but responses have been mostly positive, Luwungu said.

“People make jokes but it doesn’t discourage me,” she said. “That only pushes me to do this more.”

Before it became the worst day of her life, Allison Norland spread a blanket on the grass outside her father-in–law’s house so her infant daughter could crawl on the soft ground. New to motherhood, her first child was a surprise. “I found out when I was six and a half months pregnant, which was unbelievable for me,” she said. “Then I went to the hospital, found out I was in labor, obviously still using.”

The daughter of an alcoholic, Allison says she has a highly addictive personality. Her drug use started with marijuana when she was 18. “I would start kind of hanging out with my sister and the older crowd and drink, and then the coke [cocaine] started. I was actually dating a man at the time who was selling weed and cocaine. So, easy access I guess,” she told us.

At 19, she met the man she would eventually marry. He introduced her to Oxycodone, a commonly prescribed, but highly addictive, semi-synthetic opioid.

“We started using when we would go out of town to visit his friends and then it kind of proceeded to [finding] some people down where we live who were selling [Oxycodone] and it kind of became more common place,” she said.

After two back-to-back car accidents while driving high, she was sent to a pain doctor for her injuries. “It was straight to 30 milligrams of Oxycodone. I was getting 90 pills a month. That doctor shut down and I went to another doctor and proceeded to 150 pills a month,” she said. “I was using every day.”

Pain medication

She says the doctors never asked her if she had a history of illegal drug use or had ever abused opioids. Estimates are six out of 10 heroin users on the street started out with pain medication prescribed by a doctor. As the opioid crisis has exploded across the country, the medical community has come under scrutiny for the way they treat pain, and addiction specialists often point a finger directly at the conduct of the medical community.

Allison developed what she described as an intense addiction. The birth of her daughter was her wake-up call. Her obvious drug use was called to the attention of child protective services in Miami-Dade County where she lived. She says they almost took her newborn from her.

“I was so guilty and so ashamed that I had let that go on as long as I did. But I had her, she was healthy, no withdrawal symptoms, no anything,” she said.

She stayed clean for seven months. Then tragedy struck. As Allison watched her daughter play on the blanket that day in the back yard, her father-in-law accidentally drove his car off the driveway, striking and killing the little girl.

After seeing her daughter in the hospital for the last time, Allison drove straight to where she knew she could get pills. She says she used every day for the next year.

“Every day I pushed the limit further and further because I didn’t know how to be anymore, and what to be anymore. To go from being a mom and loving this thing so much, so much more than I love myself, to having her gone and this absence in my heart, it was really hard,” she said.

The incident left Allison with Post-Traumatic Stress Syndrome, and depression. The years passed in a fog. After an arrest, and time at another rehabilitation facility, Allison was ordered by the court to go to The Village, in Miami Florida, one of several residential and outpatient rehab centers run by Westcare, a non-profit healthcare corporation that specializes in addiction services.

Treating addiction

At first, she was hostile toward being at The Village, a renovated old Florida motel-style complex a few blocks from Biscayne Bay in the Edgewater neighborhood north of downtown Miami. Now 28, Allison sat with us in the room she shares with two other women, the walls lined with metal bunk beds and cabinets decorated with family pictures.

“I snuck in phones [which are forbidden]. I would get caught smoking on the facility, but then again I fought a lot. I fought in here, I fought out there. I just fought. I was so angry and broken down that I couldn’t be that person anymore,” she said.

Allison was initially ordered to stay at the facility for 90 days. She has chosen to stay longer. Now in her fourth month, she has slowly begun to unravel the threads of her addiction. The problems were not socio-economic. “I didn’t grow up on the streets,” she told us. “My family was upper middle-class.”

For decades, opioid abuse predominantly affected people of color in poverty-wracked inner cities. Today’s crisis has moved into the white middle-class suburbs and spread to small towns across the country.

When we asked her what an addict loses, she said “everything.” At the core of her loss were the morals and values she grew up with.

“To learn to look people in the eye and tell the truth because that is a big part of addiction – lying. I have to learn how to look people in the eye. I have to learn how to stand up straight. I have to learn how to love myself. That is what I lost most of all,” she said.

The Village uses a combination of medication, and individual and group therapy to treat its clients.

Patients are given Suboxone, a synthetic opioid strip that dissolves under the tongue. There has been some controversy with treating opioid addiction with opioids, but The Village says it has used Suboxone with great success. Delivered in small doses, the strips can eliminate withdrawal symptoms in 15 minutes. Suboxone also eliminates the cravings for opioids with limited side effects. Clients continue on the drug for months.

“With medication, we can begin to have an effect on your cravings for drugs and keep you engaged in your recovery,” says Frank Rabbito, senior vice president for Westcare, which runs The Village. “Medication keeps you away from illegal drugs and gives you an opportunity to engage in your recovery, be monitored by us for a period of time, and move toward a greater independent lifestyle.”

Therapy sessions

Allison credits the relationship and trust she has built with her therapist for her turnaround. Like many substance abusers, she has a history of physical, mental and sexual abuse going back to her childhood.

“I would say 80 percent of substance users have trauma in their past,” said Alexandra Kirkland, a therapist who works with patients at The Village. “And it causes them to have depressive symptoms. So when they flash back and think about the trauma, it breaks into their daily functioning, and many times they use substances as an escape to deal with the trauma.”

“My therapist has been incredible and has helped me through things I have done in the dark that I never thought would come to light,” Allison told us. “There are things that happened to me that I never wanted to talk about I have talked about with her. And it is because I know she can understand.”

The sessions have helped her confront some painful realities, such as using drugs while pregnant.

“I put my daughter in harm’s way for a pill. I put my life in danger for a pill. I was risking everything for this drug. And that is it – chasing a high that was never going to be enough, “she said.

It’s hard to reconcile the darkness she describes with the person in front of us; she now carries herself with an air of happiness and confidence, and can flash a smile that lights up the room. Allison wants to stay even longer at the The Village and further her recovery.

The odds are against her. Researchers estimate a mere three percent of addicts stay clean for life.  Allison is not deterred. She now wants to become an addiction specialist.

“That is my goal,” she says, brimming with energy. “It is exciting to work toward something. That is a huge thing. I want to help people. People like me.”

At the summit of one of Iceland’s most dangerous volcanoes, a 72-foot (22-meter) depression in the snow is the only visible sign of an alarming development.

The Oraefajokull volcano, dormant since its last eruption in 1727-1728, has seen a recent increase in seismic activity and geothermal water leakage that has worried scientists. With the snow hole on Iceland’s highest peak deepening 18 inches (45 centimeters) each day, authorities have raised the volcano’s alert safety code to yellow.

Experts at Iceland’s Meteorological Office have detected 160 earthquakes in the region in the past week alone as they step up their monitoring of the volcano. The earthquakes are mostly small but their sheer number is exceptionally high.

“Oraefajokull is one of the most dangerous volcanos in Iceland. It’s a volcano for which we need to be very careful,” said Sara Barsotti, Coordinator for Volcanic Hazards at the Icelandic Meteorological Office.

What worries scientists the most is the devastating potential impact of an eruption at Oraefajokull.

Located in southeast Iceland about 320 kilometers (200 miles) from the capital, Reykjavik, the volcano lies under the Vatnajokull glacier, the largest glacier in Europe. Its 1362 eruption was the most explosive since the island was populated, even more explosive that the eruption of Italy’s Mount Vesuvius in 79 A.D. that destroyed the city of Pompei.

Adding to the danger is the lack of historical data that could help scientists predict the volcano’s behavior.

“It’s not one of the best-known volcanos,” Barsotti said. “One of the most dangerous things is to have volcanos for which we know that there is potential for big eruptions but with not that much historical data.”

Iceland is home to 32 active volcanic sites, and its history is punctuated with eruptions, some of them catastrophic. The 1783 eruption of Laki spewed a toxic cloud over Europe, killing tens of thousands of people and sparking famine when crops failed. Some historians cite it as a contributing factor to the French Revolution.

The Eyjafjallajokull volcano erupted in April 2010, prompting aviation authorities to close much of Europe’s airspace for five days out of fear that its volcanic ash could damage jet engines. Millions of travelers were stranded by the move.

To remedy the lack of data for Oraefajokull, scientists are rushing to install new equipment on and around the volcano. Those include ultra-sensitive GPS sensors that can detect even the slightest tremors, webcams for real-time imagery of the volcano and sensors in the rivers that drain the volcano’s glaciers to measure the chemical composition of the water.

Associated Press journalists last week visited scientists working near the mouth of the Kvia River, where the stench of sulfur was strong and the water was murky, clear signs that geothermal water was draining from the caldera.

“The most plausible explanation is that new magma is on the move deep below the surface,” said Magnus Gudmundsson, professor of geophysics at the Institute of Earth Sciences in Reykjavik.

But what happens next is anyone’s guess. In the most benign scenario, the phenomenon could simply cease. More concerning would be the development of a subglacial lake that could lead to massive flooding. At the far end of the spectrum of consequences would be a full eruption.

With such high-risk developments at stake, authorities are taking precautions. Police inspector Adolf Arnason now is patrolling the road around the volcano, which will be used for any evacuation, and residents have received evacuation briefings.

“Some farmers have only 20 minutes (to leave),” he said, pulling up to a small farm on the flank of the mountain.

If an evacuation is ordered, everyone in the area will receive a text message and the radio will broadcast updates. Police are confident that Oraefi’s 200 residents will know how to react, but their biggest concern is contacting tourists.

Iceland has seen a huge boom in tourism since the 2010 eruption — a record 2.4 million people are expected to visit this year and about 2,000 tourists travel through Oraefi every day. While some stay in hotels that could alert their guests, others spend the night in camper vans spread across the remote area.

“The locals know what to do. They know every plan and how to react. But the tourists, they don’t,” said Police Chief superintendent Sveinn Runarsson. “That’s our worst nightmare.”

Within seconds of pulling out of the station parking lot, Major Mike Will gets his first call to respond to a crisis. Wills switches on his lights and siren and picks up the pace.

A thirty-year veteran of the Louisville’s emergency medical services, he has witnessed the explosion in opioid overdoses that have ravaged the city over the past two-years.

“The information we have right now is a 52-year old adult male who is unconscious, CPR in progress. And it look like an overdose,” he tells us.

The epidemic is taking a toll on Louisville’s first responders who field an average of over 20 overdose calls a day.

“When I first started, we could anticipate making narcotic or opioid overdose calls maybe five times a year,” he says. “And in the past year or two we have several of our crews that are making five in a 12 or 16 hour shift.”

As overdoses have steadily risen in cities and small towns across the country, officials have been searching for answers. Louisville reached a crisis point last August, with 151 overdoses over a span of four days.

Doctor on the front lines

Dr. Robert Couch, an emergency room physician and medical director at Louisville’s Norton Audubon Hospital, was on call at that time. He saw nine overdoses in five hours.

“We have been seeing heroin overdoses for a long time. But what was unusual about this overdose experience was it was taking larger and larger doses of the antidote Naloxone to reverse the effects of it,” he says. “So we knew that it wasn’t just heroin.”

Couch had learned of a similar spike in overdose cases in Ohio and West Virginia several weeks earlier. According to toxicology reports, those cases were caused by heroin mixed with Carfentanil, an opioid derivative often known as “the elephant tranquilizer,” that is 5,000 times more powerful than heroin.

“It is toxic in microgram quantities,” says Couch. “And so I suspected what other communities had seen was moving into Louisville at that time.”

According to the U.S. Drug Enforcement Administration, Fentanyl and Carfentanil are synthetic opioids predominantly manufactured in underground laboratories in China. Often sold as research chemicals, they can be bought on the dark web.

Cheaper to produce than heroin, they are often delivered to the U.S. through the mail. Dealers then mix the synthetics with their heroin to boost profits. The results are often deadly.

“Unfortunately, users don’t know what they are getting,” says Couch. “Heroin is toxic enough as it is. These other derivatives can cause death almost immediately through respiratory depression.”

Fentanyl and its derivatives have forced emergency rooms across the country to change their protocols for overdose patients.

“A couple of years ago we would start with a very small dose, say 0.4 milligrams of Naloxone and that would be effective,” Couch tells us. “That dose has increased to about 2 milligrams and now we are using 4 milligrams of Naloxone just to restore breathing initially.”

Naloxone can suppress opioids in the body for about 30 minutes, which is long enough to treat a typical heroin overdose. The Fentanyl derivatives are so potent emergency rooms are having to re-dose patients as the Naloxone wears off.

“People can re-sedate and be right back in the throes of their overdose even though they have been administered the reversal agent,” Couch says.

Fear on the streets

As overdoses have risen, so has fear on the street among drug users.

“To find a bag of heroin is pretty rare – that is just heroin,” says Mathew LaRocco, who runs the Louisville Metro Needle Exchange out of the first floor of a city government building. The exchange provides clean needles and other supplies to 400 drug users a week.

Studies have shown that drug users who frequent needle exchanges are 5 times more likely to seek treatment and less likely to contract HIV, hepatitis, and other health problems associated with intravenous drug use.

LaRocco works closely with the drug-using community in metro Louisville and says people are legitimately scared.

“There is a lot more respect for the product that is on the street,” he says. “People are realizing just how dangerous this is.”

LaRocco says several years ago when Fentanyl first came on the scene there was a small subset of users – usually young male users – who had the attitude that it would never happen to them.

“You don’t see that anymore,” he says. “You are seeing a volatility to the drug where people who used to inject five times a day are now injecting 15 times a day. They are still using the same amount of drug throughout the day, they are just breaking it up into smaller doses because they don’t want to die.”

He says Fentanyl and its derivatives are also showing up in other street drugs like methamphetamine.

“I have a client that only shoots methamphetamine,” says LaRocco. “He doesn’t shoot anything else. He was drug-screened and there was Fentanyl in his screen.”

LaRocco says even with the fear on the streets it is still difficult for an addict to overcome their irrational cravings.

“That still doesn’t change the fact that when someone overdoses on a bag of dope, everybody want to figure out where they got that bag of dope from. Because they know it is going to get them high,” he told us.

Lucky man

Major Mike Will arrives on the scene and pulls up behind a fire truck parked in a middle-class, suburban neighborhood lined with sidewalks. Two police officers are standing in the yard of a modest house with a brick front porch. Inside, paramedics are administering Naloxone, the opioid antidote, and the patient begins to regain consciousness.

“The transport unit was right on top of the run,” says Will. “So that gives this individual a much better chance because the first responders were so close. Apparently we had a two minute response time.”

A few minutes later, a white man with graying hair walks out under his own power and lays on a gurney waiting for him in the front yard – cheating certain death. Major Wills says he’s one of the lucky ones.

“You know these people we are bringing back with Naloxone, it’s giving them a second chance,” he says. “And it is frustrating to see these folks doing it over and over again. But I mean, you know, addiction is a sickness. And these people are addicted.”

The World Health Organization warns the number of people living with dementia globally will triple from 50 million to 152 million by 2050.  WHO is launching a global monitoring system on dementia, which will track progress and identify areas of concern.

The WHO reports dementia exacts a huge social and economic burden, one that will grow as people age and succumb to this mental illness.  

The agency estimates five percent of the world’s older population suffers from dementia and is in need of care.  Belying common belief, WHO says this is not mainly a problem of rich countries as dementia also affects people living in poorer countries.

The health agency says the cost of caring for dementia patients today is $818 billion or one percent of the world’s Gross Domestic Product.  Tarun Dua is a medical officer in WHO’s Department of Mental Health and Substance Abuse.  She says this economic cost will be more than $2 trillion by 2030.

“Moreover, there is stigma, human rights violations associated with people with dementia and their caregivers,” said Dua. “And, therefore, it is imperative that we have a public health response.  An important step that has been taken by all member States has been endorsing an action plan on dementia this year.” 

She says the plan focuses on caring for people who have dementia, on preventing and on finding a cure for this illness.  She says raising awareness of this problem is essential.

“Many people consider that dementia is a normal part of ageing, which is not true,” said Dua. “We need to think about risking, preventing dementia because the risk factors for dementia are the same for communicable diseases.  So, good exercise, good diet, no tobacco, decreasing alcohol, all of this can decrease the risk of dementia.”

Along with this, she says elderly people who suffer from depression should receive treatment for this malady.  She says social inclusion and cognitive exercise are other strategies that should be employed to reduce the risk of dementia.

A group of 2017 Nobel Laureates have addressed the lack of female representation in sciences ahead of the prize-awarding ceremony in Stockholm.

The seven winners of this year’s Nobel Prize in Physics, Chemistry and Economic Sciences – all white men – said change is happening.

Jacques Dubochet, who won the chemistry prize, told reporters: “Science has been made by males, for males. It is changing, it takes time, but you will see it, they (women in science) are coming.”

Physicist Kip Thorne pointed to the increase in the number of women entering undergraduate programs in sciences today compared to when he was a student.

He said Thursday: “Change is coming, but there is a long delay between entering freshman and the Nobel prize.”
