A woman became the third person ever to be cured of HIV, the virus that causes AIDS, after she received a stem-cell transplant that used cells from umbilical cord blood, scientists reported Tuesday (Feb. 15). The two other people cured of HIV, Timothy Brown and Adam Castillejo, both received bone marrow transplants from donors who carried a genetic mutation that blocks HIV infection, Live Science previously reported. These transplants contained adult hematopoietic stem cells, which are stem cells that develop into all types of blood cells, including white blood cells, a key component of the immune system.

The mysterious source of a globe-spanning tsunami that spread as far as 6,000 miles (10,000 kilometers) from its epicenter was an “invisible” earthquake, a new study has found. In August 2021, an enormous tsunami rippled out into the North Atlantic, Pacific and Indian oceans. It was the first time a tsunami had been recorded in three different oceans since the catastrophic 2004 Indian Ocean earthquake; at the time, scientists thought it was caused by a 7.5-magnitude earthquake detected near the South Sandwich Islands (a British Overseas Territory in the southern Atlantic Ocean).

LIFE’S LITTLE MYSTERIES
What are the largest impact craters on Earth?

In its 4.5 billion-year existence, Earth has been punched and gouged by hundreds of large asteroids that have slammed into its surface. At least 190 of these collisions have left colossal scars that are still visible today. But not every space rock that zips into our planet’s atmosphere makes it to the ground. So what does it take for an asteroid to make a dent on Earth, and which known impact events have left the biggest craters? Most space rocks that barrel into Earth’s atmosphere aren’t giant at all. They’re very small — around 3 feet (1 meter) across, according to NASA. That’s good for Earthlings, as any space rock less than 82 feet (25 m) in diameter usually won’t make it past Earth’s atmosphere, NASA reported. The space rock’s super high speeds heat up the gases in the atmosphere, which burn away the space rock (which technically becomes a meteor once it meets the atmosphere) as it passes through. In most cases, any space rock remnant that makes it through the atmosphere will cause little or no damage if it reaches the ground.

This week, you can lunch with the Snow Moon, which will appear at its fullest at 11:57 a.m. EST (1657 GMT) on Wednesday, Feb. 16. If you can’t make this lunar lunch date, the moon will still be a perfect companion for other outdoor activities, appearing full for three days, from Tuesday (Feb. 15) through Thursday night (Feb. 17), according to NASA.

The ocean’s ingenious climate solutions
Susan Ruffo
The ocean is often thought of as a victim of climate change, in need of human protection. But ocean expert Susan Ruffo says that mindset needs to shift. From storing carbon to providing protection to coastal communities, Ruffo highlights the ocean’s ready-made solutions to the climate crisis and asks: With more than eighty percent of the ocean still unexplored, what new solutions are waiting to be discovered?

The forest is our teacher. It’s time to respect it
Nemonte Nenquimo
For thousands of years, the Amazon rainforest has provided food, water and spiritual connection for its Indigenous inhabitants and the world. But the endless extraction of its natural resources by oil companies and others is destroying the lives of those who live there, says Waorani leader Nemonte Nenquimo, and threatening the overall stability of Earth’s biosphere. In this powerful talk, she reminds us of the destruction that continues to happen to the world’s largest tropical rainforest — and demands respect for Mother Nature. “The forest is our teacher,” she says. (Filmed in Ecuador by director Tom Laffay and associate producer Emily Wright, in collaboration with Amazon Frontlines. In Spanish with subtitles.)

The powerful women on the front lines of climate action
Farwiza Farhan
When it comes to big problems like climate change, we tend to focus on big solutions — but many of the best ideas come from people on the ground, facing day-to-day conservation battles. Sharing her effort to protect the Leseur ecosystem in Indonesia (the last place on Earth where the Sumatran rhino, tiger, elephant and orangutan still roam together in the wild), TED Fellow and conservationist Farwiza Farhan explains the challenges women face on the front lines of forest preservation within patriarchal societies — and the resilient, world-changing power they hold.

Women and girls, you are part of the climate solution
Rumaitha Al Busaidi
What does gender equality have to do with climate change? A lot more than you might think. Empowering women and girls around the world is one of the most important ways to combat carbon pollution and is projected to reduce CO2-equivalent gases by a total of 80 billion tons. Entrepreneur, scientist and TED Fellow Rumaitha Al Busaidi looks at why women are more likely to be impacted and displaced by climate catastrophes — and explains why access to education, employment and family planning for all women and girls is the key to our climate future.

Western states face a bleak future amid the worst drought in more than 1,000 years
Feb 15, 2022 PBS NewsHour
The so-called megadrought that is afflicting the American West is the worst in 1,200 years, according to a study published this week. It has dried up water supplies, threatened ranchers and fueled wildfires. Park Williams, the lead author of the study just published in the journal Nature Climate Change, joins William Brangham with more.
