YouTube announced Thursday it wants to help people make informed health care decisions by allowing more medical sources to share videos on its platform.  

“At YouTube, we’re working to make it easier for people to find authoritative information to help answer their questions, and we’re putting health professionals at the core of our efforts to connect people with helpful content,” the company said on its website. 

Doctors, nurses, and other health care professionals can now apply to have their video channels certified to participate in You Tube’s health features, something that, until now, has only been available to educational institutions, public health departments, hospitals and government entities.

“The reality is that the majority of healthcare decisions are made outside the doctor’s office, in the everyday lives of our patients,” YouTube said.  “That’s why YouTube Health has been working on additional ways to help doctors, nurses, mental health professionals and health care information providers to bring high quality health information into the spaces that people visit throughout their day – like their favorite video-sharing app. 

“This new step will allow us to expand to include high quality information from a wider group of health care channels,” the company said.

YouTube has been criticized in the past for being home to some misinformation about COVID-19 vaccines but has since banned the misleading information.

Hawaii officials are warning residents of the Big Island that the world’s largest active volcano, Mauna Loa, is sending signals that it may erupt.

Scientists say an eruption isn’t imminent, but they are on alert because of a recent spike in earthquakes at the volcano’s summit. Experts say it would take just a few hours for lava to reach homes closest to vents on the volcano, which last erupted in 1984.

Hawaii’s civil defense agency is holding meetings across the island to educate residents about how to prepare for a possible emergency. They recommend having a “go” bag with food, identifying a place to stay once they leave home and making a plan for reuniting with family members.

“Not to panic everybody, but they have to be aware of that you live on the slopes of Mauna Loa. There’s a potential for some kind of lava disaster,” said Talmadge Magno, the administrator for Hawaii County Civil Defense.

The volcano makes up 51% of the Hawaii Island landmass, so a large portion of the island has the potential to be affected by an eruption, Magno said.

There’s been a surge of development on the Big Island in recent decades — its population has more than doubled to 200,000 today from 92,000 in 1980 — and many newer residents weren’t around when Mauna Loa last erupted 38 years ago. All the more reason why Magno said officials are spreading the word about the science of the volcano and urging people to be prepared.

Mauna Loa, rising 13,679 feet (4,169 meters) above sea level, is the much larger neighbor to Kilauea volcano, which erupted in a residential neighborhood and destroyed 700 homes in 2018. Some of its slopes are much steeper than Kilauea’s so when it erupts, its lava can flow much faster.

During a 1950 eruption, the mountain’s lava traveled 15 miles (24 kilometers) to the ocean in less than three hours.

The Hawaiian Volcano Observatory, which is part of the U.S. Geological Survey, said Mauna Loa has been in a state of “heightened unrest” since the middle of last month when the number of summit earthquakes jumped from 10 to 20 per day to 40 to 50 per day.

Scientists believe more earthquakes are occurring because more magma is flowing into Mauna Loa’s summit reservoir system from the hot spot under the earth’s surface that feeds molten rock to Hawaii’s volcanoes.

The temblors have declined in frequency in recent days but could rise again.

More than 220 people attended a community meeting last weekend that county civil defense officials held in Ocean View, a neighborhood that lava could reach in hours if molten rock erupts through vents on Mauna Loa’s southwest flank.

Bob Werner, an Ocean View resident who didn’t attend the meeting, said it’s wise to be aware of a possible eruption but not to fear it. He’s not concerned that the neighborhood would be completely cut off, if lava flows across the only road connecting it to the bigger towns of Kailua-Kona and Hilo, where many people do their shopping.

The “greater concern is it will be extremely annoying to drive an extra hour or two hours to get the same stuff,” he said.

Ryan Williams, the owner of the Margarita Village bar in Hilo, said the volcanic unrest wasn’t worrying customers who are used to warnings.

There could still be a heightened sense of urgency since officials have been holding town hall meetings, urging people to prepare.

“But everything I’ve read or heard, they trying to kind of assure people that conditions have not changed,” Williams said. “There’s no imminent eruption, but just to be alert.”

Magno said his agency is talking to residents now because communities closest to vents likely wouldn’t have enough time to learn how to respond and prepare once the observatory raises its alert level to “watch,” which means an eruption is imminent.

The current alert level is “advisory” meaning the volcano is showing signs of unrest yet there’s no indication an eruption is likely or certain.

Residents in other parts of the island would have more time to react.

Lava from Mauna Loa’s northeast flank could take days or weeks to reach residential communities. That’s because the mountain’s slopes on that side are relatively gentle and because towns are farther from volcanic vents.

Frank Trusdell, research geologist at the Hawaiian Volcano Observatory, said all of Mauna Loa’s eruptions in recorded history have started in its summit crater. About half of them stayed there, while the other half later spewed lava from vents lower down the mountain.

Lava erupting from the summit generally doesn’t travel far enough to reach residential areas.

Mauna Loa has erupted 33 times since 1843. It last erupted in 1984 when lava flowed down its eastern flank only to stop 4.5 miles (7.2 kilometers) short of Hilo, the Big Island’s most populous town.

Mauna Loa also has a history of disgorging huge volumes of lava.

In the 1950 eruption, which lasted for 23 days, Mauna Loa released 1,000 cubic meters (1,307 cubic yards) of lava per second. In contrast, Kilauea released 300 cubic meters (392 cubic yards) per second in 2018.

The earthquakes could continue for a while before any eruption: increased seismic activity lasted for a year before a 1975 eruption and a year-and-a-half before the 1984 one. Alternatively, the temblors could subside and Mauna Loa may not erupt this time.

Trusdell said residents should look at his agency’s maps and learn how quickly lava may show up in their neighborhood. He also urged people living in one of the short-notice areas to pay attention if the summit turns red.

“All you got to do is look up there and see the glow. You grab your stuff, throw it in the car and drive. Go!” he said.

They can always go home after if the lava ultimately doesn’t flow into their neighborhood, he said.

Tuberculosis case numbers increased from 2019 to 2021, reversing years of progress as the COVID-19 pandemic disrupted access to treatment and testing, the World Health Organization said Thursday. 

“For the first time in nearly two decades, WHO is reporting an increase in the number of people falling ill with TB and the drug-resistant tuberculosis, alongside an increase in TB related deaths,” said Tereza Kasaeva, director of the U.N. health agency’s global TB program. 

A WHO report released Thursday stated that more than 10 million people got tuberculosis in 2021, a 4.5% increase from 2020. Roughly 450,000 cases involved individuals infected with the drug-resistant TB strain, a 3% increase from 2020 to 2021. Most of these cases were reported in India, Indonesia, Myanmar and the Philippines.

The COVID-19 pandemic “continues to have a damaging impact on access to TB diagnosis and treatment,” WHO said. COVID-19 restrictions, such as lockdowns and physical distancing, resulted in fewer people being diagnosed and getting the necessary treatment. With fewer people being diagnosed and treated for TB, more patients unknowingly spread the disease to others. As a result, more than a decade of progress was lost, said Dr. Mel Spigelman, president of the nonprofit TB Alliance. 

Tuberculosis is caused by bacteria that attack the lungs. The disease is mainly spread through the air and, after COVID-19, tuberculosis is the world’s deadliest infectious disease. It primarily affects adults, particularly those who are malnourished or immunocompromised, in developing countries. More than 95% of cases are in developing countries.

The downturn of the global economy during the pandemic worsened the problem, as families faced unbearable costs due to their treatment, especially in developing countries. 

Dr. Hannah Spencer, with Doctors Without Borders in South Africa, suggested lowering the prices of tuberculosis treatment to no more than $500 to help low-income patients. WHO also suggested that more countries should cover the cost of TB diagnosis and treatment. 

“If the pandemic has taught us anything, it’s that with solidarity, determination, innovation and the equitable use of tools, we can overcome severe health threats,” WHO Director-General Tedros Adhanom Ghebreyesus said in a news release Thursday. “Let’s apply those lessons to tuberculosis. It is time to put a stop to this long-time killer.”

GENEVA – A U.N. report warns the window for preventing a climate catastrophe is fast closing. The U.N. Environment Program’s latest Emissions Gap Report urges unprecedented cuts in greenhouse gas emissions and a rapid transformation of societies to head off the worst.

The U.N. report finds the world is falling far short of the Paris climate goals agreement, with no credible pathway for limiting a temperature rise to 1.5 degrees Celsius by the end of the century.

UNEP Executive Director Inger Andersen said progress since last year’s climate change conference, COP 26 in Glasgow, Scotland, has been woefully inadequate. She said nations have failed to deliver on their pledges for greater emissions cuts.

She noted greenhouse gas emissions must be cut by 45 percent by 2030 to stop climate change. However, instead of stabilizing global temperatures at 1.5 degrees above the pre-industrial level, she said temperatures will likely rise 2.4 to 2.6 degrees by 2100.

“We are sliding from climate crisis to climate disaster. This report is sending us a very, very clear message. If we are serious about climate change, we need to kickstart a system-wide transformation now. We need a root and branch redesign of the electricity sector, of the transport sector, of the building sector, and food systems.”

Additionally, she said financial systems must be reformed so they can bankroll the required transformations. She says incremental changes no longer are an option. Bold action must be taken now.

Secretary-General of the World Meteorological Organization Peterri Talaas called the transformational changes doable. He noted the IPCC, Intergovernmental Panel on Climate Change, earlier this year reported that prices of climate-friendly energy solutions have been dropping.

“Nowadays, it is cheaper to invest in solar or wind energy as compared to the fossil energy. And the good news is also that 32 countries have reduced their emissions during the past 15 years, whereas their economies have been growing. So, there is not an automatic connection between economic growth and emissions growth.”

He mentioned European countries, the United States, Japan, and Singapore as some of the countries that have managed to grow their economies while reducing emissions.

Environmental experts estimate a global transformation to a low-emissions economy is expected to require investments of at least $4 trillion to $6 trillion a year. They are urging nations attending next week’s COP27 in Sharm el-Sheikh, Egypt, to agree to foot the bill and to up their pledges to cut greenhouse gas emissions.
