Everyone who lived through Black Saturday remembers the heat and the wind that day in February 2009. The temperature soared to 115 degrees Fahrenheit — so hot it sucked the breath out of you, made your vision swim and your fingers swell. The wind blew in from the northwest, from the vast, arid Australian interior. Flags flew stiff. Fire danger was extreme.

Coming off a shift at Tuen Mun Hospital in Hong Kong on Wednesday night, cardiologist Alfred Wong was getting ready to go to dinner with his wife. The last time they ate together, she brought the meal to the courtyard below their apartment, placed it on a bench, then sat down at least 10 feet away.

From across the patio, they ate. On separate benches. Looking at each other.

First came the fires, denuding millions of acres of forest in eastern Australia. Now comes the rain, more than 12 inches in just 48 hours over this past weekend in some areas of New South Wales.

That sequence, severe bushfires followed by torrential rain, is bringing a third cataclysm — landslides and large-scale erosion.

When Linda and Bob Oslin lost their home last year to California's most destructive wildfire, they began searching their burned property expecting to salvage at least some sentimental items.

But, she says, "everything was gone." Or so she thought.

At first, Stephen DiRado thought his dad was dealing with depression. Gene DiRado, then in his late 50s, had become more withdrawn, more forgetful. So Stephen processed his growing concern by doing what he'd done since the age of 12: taking photographs. It was the 1980s, and Stephen schlepped his 8x10 camera and tripod over to his parents' home in Marlborough, Mass., to check in on Gene and make portraits of him.

"I was running toward him with the sense of fear that something was wrong," Stephen says now about those years.

When Ayanna Howard was a little girl, her favorite TV show was the Bionic Woman.

It's been one week since Hurricane Irma hit Southwestern Florida. Residents in Collier County, where the storm made landfall after the Florida keys, are in the early stages of the recovery process still cleaning up debris, wading through floodwaters, struggling to get gas, and trying to get by without electricity. It will take months to fully assess the damage, and the rebuilding process could take years. Yet already they are looking ahead to the next steps. They are figuring out how to continue with their lives amidst the devastation.

Within weeks of being diagnosed with breast cancer at 29 years old, Nicole O'Hara of Phoenix, Md., underwent a double mastectomy. She had breast reconstruction during the same operation; then it was on to chemotherapy.

The ordeal left O'Hara with "big, ugly, red inflamed scars and stitches and drains," she says.

"It [was] a battlefield."

When Mexican-American artist Nora Litz first talked with her students about immigration — she was shocked to hear how scared they were.

After years working as a nurse in critical care units, Anne Webster found herself lying in the hospital struggling to get well. She had been given the wrong dose of a chemotherapy medication to treat Crohn's disease. The mistake had caused her bone marrow to shut down, and she'd developed pneumonia.

As she lay in the hospital, she thought, "If I live, I'm gonna write about this."

After three weeks, she recovered. And the experience led Webster to write Chemo Brain, a poem about how the drug scrambled her thinking.

According to Audrey Shafer, there is something profound in the moment a patient wakes up from surgery.

She would know — she's an anesthesiologist. She's responsible for people when they are at their most vulnerable: unconscious, unable to breathe on their own or even blink their eyes.

As a result, Shafer says, a kind of intimate trust forms between her and her patients. It's this closeness that moves her to write poetry about medicine.

Inside the walls of a geriatric hospital in France, time stands still. Light falls across two stockinged feet on a bed. The fading floral pattern on a swath of wallpaper is interrupted by an unused corkboard. And between these scenes of stillness, residents approach a pair of locked doors with modest curiosity, expectation and even anger.

Swedish photographer Maja Daniels says those doors, which were locked to prevent the residents from wandering, were crucial early in the project.

In 2008, Dana Walrath asked her mother Alice to move in with her. Alice's Alzheimer's disease had gotten worse, and even though she still had all her humor and graces, she could no longer take care of herself.

During the next two and-a-half years, Walrath and her mother connected through stories and memories, even though Alice didn't always recognize her daughter. Walrath, a medical anthropologist at the Vermont College of Medicine, in Burlington, Vt., looks back fondly on that time.

"My name is Becki," says a young woman standing in a convention center turned comic book bazaar. Then she flips a mane of orange hair and launches into Scottish accent. "And today, I am Merida from Brave."

When Architect Matthias Hollwich was approaching 40, he wondered what the next 40 years of his life might look like. He looked into the architecture that serves older adults, places like retirement communities and assisted living facilities, and didn't like what he saw. But what if we changed our habits earlier in life so we could stay in the communities we already live in?

When Ryan Green's son Joel was 1 year old he was diagnosed with an aggressive brain cancer. Over the next few years, he underwent rounds of chemotherapy and radiation, only to have the cancer return.

Do you remember cutting paper snowflakes in school? Artist Rogan Brown has elevated that simple seasonal art form and taken it to science class.

These large-scale paper sculptures may evoke snow, but actually trade on the forms of bacteria and other organisms. The patterns may feel familiar, but also a bit alien. You're not looking at a replica of a microbe, but an interpretation of one. And that distinction, Brown says, is important.

Hispanic people much are less likely to get cancer than non-Hispanic whites, but it's also their leading cause of death.

Beneath that puzzling fact lie the complexities and contradictions of the Hispanic health experience in the United States. Since we're talking about 17 percent of the U.S. population, it has ramifications for health care and the economy.

Here's what caught our eye in Wednesday's report on cancer and Hispanics from the American Cancer Society:

When it comes to sports, there seems to be something for everyone.

There are team sports and activities you can do alone. There's exercise that requires equipment, or none at all.

But how much benefit you get from each one depends on a lot of factors, including how much you weigh, how long you play and the intensity of the activity.

It wasn't until Deborah Svoboda dated someone who is trans that she understood how little she understood about being transgender. "I realized how very misunderstood they were, including by me," she says. And that comes from someone who identifies as queer and has lived and worked in diverse communities.

When Erik Christiansen started smoking pot, he became fascinated by the look of different marijuana strains. But the photographs of marijuana he saw didn't capture the variety.

So he went to the hardware store and picked up two lights and a cardboard box. "I didn't even have a macro lens — I was shooting through a magnifying glass," he says.

The California-based photographer tinkered with his macro technique until he had created a consistent way to capture highly detailed images of marijuana.

A month after her father died of sepsis, Jennifer Rodgers began creating maps.

She took a large piece of paper, splattered it with black paint and then tore it into pieces. Then she began to draw: short black lines mimic the steps she walked in the hospital hallway during her father's hospitalization.

"It was a physical release of emotion for me," she says.
