The Fungal Pioneer: A Life Exhibition

On an early summer day of 1876 near Druid Hill Park in Baltimore, a middle-aged woman carrying three large, corrupt mushrooms repelled fellow travelers in horse-drawn carriages.

Even wrapped in paper, the foul smell of the aptly named Stinkhorn mushroom was overwhelming, but the woman suffocated her laughter as two other passengers griped about the surrounding flies. The smell didn’t bother her. All she cared about was to bring specimens home to study them, she would write later.

This is Mary Elizabeth Banning, a self-taught mycologist who has been doing creative research into Maryland fungi for nearly 40 years.

Miss Bunning characterized thousands of specimens she found in the countryside of Baltimore and its surrounding areas, identifying 23 new species in science at the time.

The talented artist has collected these observations into a manuscript called “Maryland Fungi.” It consisted of 175 stunning watercolor paintings, each with an accurate yet intimate portrait of a particular species, as well as detailed scientific explanations and anecdotes about the collection of mushrooms.

The manuscript was Miss Bunning’s life work, and she wanted to see it published. But it ended in the drawers of the New York State Museum in Albany and has been forgotten for almost a century.

Her watercolors make up the backbone Exhibition at the museum It will open this month and will run until January 4th next year. The exhibition, called “Outcasts,” recognizes not only the museum’s Mycology collection, but also the museum’s Mycology Collection, as well as the museum’s Mycology Collection.

Miss Banning is known as the fungus “vegetable exile.” At the time (and throughout 1969) fungi were classified as distinctive plants. Most botanists From the mid-19th century, their research was considered a backwater of research.

It was the exile who banned herself. “She was very much hoping to be part of the science community,” said John Haynes, a museum’s mycology curator until she retired in 2005 and a wide-ranging study of her history. But as a woman living in the 19th century, the path was largely closed to her.

Like her contemporaries like Beatrix Potter, she tried to make her mark in the emerging field of mycology.

One scientist gave her Charles Horton Peck, who worked at the museum as New York’s first national botanist from 1868 to 1913. A prominent American mycologic man, Peck has dedicated most of his career to fungi, gathering over 33,000 specimens in a New York survey, surpassing 2,700 New New Kachiuk reports.

“A lot of the fungi that people recognize from New York and the northeast are what Peck explained,” said Dr. Kaisian.

Miss Banning first wrote Mr. Peck in 1878, seeking feedback on her manuscript. Unlike the other scientists she tried to contact, he wrote back and they responded for nearly 20 years. Her letters are part of which are on display, providing a window into their relationship.

“You are my only friend on the debate land of the Official Gazette,” she wrote to him in 1879. She recorded her collection forays and scientific observations, and conveyed her dreams of the manuscript. “I have a strong will,” she wrote in 1889.

Miss Banning’s letters were often whimsical and passionate. None of Mr. Peck’s letters to her remained, but his tone in the other letters suggested he was much more restrained. Nevertheless, he treated Miss Vanning like a respected colleague – providing her scientific guidance, an account of the species with her support, and even an account of the species named after her. Their scientific bonds could not be denied.

“It’s a love story, but not between them. They both were in love with fungi,” Haynes said. The play he wrote about their relationship from Miss Bunning’s letter will take place at the exhibition’s gallery opening event on April 4th at the museum.

However, the love triangle tends to change particularly sourly. With no visible publishing prospects for her own, Miss Bunning sent her manuscript to Mr. Peck in 1890, hoping that he could publish it. “He would have had the resources to make it a permanent part of the mycologic record,” Dr. Kaisian said. But he never did.

She expressed how difficult it was to let go of her job and asked her to reassure her that she appreciated her contribution to the field, but she was not received that recognition. “In her letter, she seems to have passed away without really understanding the legacy, the value of her work,” Dr. Kaisian said.

In one of her final letters to Mr. Peck in 1897, six years before her death, Miss Bunning lamented the loss of the book as she fell into poverty alone in a room home in Virginia. “I hardly know that I’ve given up on an illustrated book,” she wrote. “To tell you the truth, I want to look at it and call it my own again, but this is by no means.”

“It still brings tears to my eyes,” Dr. Haynes said.

It was originally Dr. Haynes who revealed the manuscript of Miss Bunning.

The eccentric curator showed it to him in 1969 when he visited the museum for a job interview. He recalls being surprised by the colors that were beautifully preserved by the fact that pages had not been opened to sunlight for decades.

He exhibited some of the paintings in 1981, and they were on display several more times, including the birth of Miss Banenning, including Talbot County, Maryland. With the help of this spotlight, Miss Bunning was led to the Maryland Women’s Hall of Fame in 1994. However, since the mid-1990s, the photographs were packed in as pigments decompose quickly in light.

Beyond Miss Bunning’s work, “Outcasts” gives visitors a glimpse into the broader historical background of mycology. “Fungi are extremely important organisms, dating back hundreds of millions of years, they shape the very texture of the Earth,” Dr. Kaisian said. “But their stories are still mystical and often ignored.”

In addition to Miss Bunning’s watercolors and letters, the exhibition includes many other artifacts and experiences. Visitors can explore one of Peck’s microscopes and mushroom specimens, one of the recently collected by Dr. Kaysian, or marvel at the incredibly realistic wax sculpture of New York fungi, created for the museum in 1917 by artist Henri Marchand and his son Paul.

The murals, created by museum artists, show the biology of fungi, their role in ecosystems, and their evolutionary history. Rare Fossils of Prototaxite, a 30-foot-high fungus that lived during the Devonian period about 400 million years ago refers to how much the Earth has changed over time.

Overall, Dr. Kaysian said he hopes the exhibition will demonstrate why such natural history collections deserve public support and preservation.

The 150-year-old specimen, hidden in a cabinet where visitors rarely see scientists, maps the limits of a variety of organisms, both geographically and genetically.

“The Natural History Collection is an active repository for contemporary research,” Dr. Kaisian said. “We need more scientific communication about what’s going on here and why it’s important.”

Fungal Networks Enhance Robotics Through Scientist’s Innovations

In today’s society, there is a growing interest in artificial intelligence (AI) and robotics due to their potential to enhance workflow, communication, and technical capabilities. However, researchers are faced with the challenge of adapting robots quickly to external stimuli for more fluid movement in their environments. To achieve this, scientists are exploring the intricate systems of brain cells that communicate through neural networks.

A team of researchers from Cornell University aimed to address limitations in robotics that computer programs have struggled with, such as short lifespan, intensive maintenance, and low responsiveness to environmental changes. They investigated the potential of improving biohybrid neural networks using living materials combined with synthetic materials to enable faster reactions to unpredictable situations and problem-solving in robots.

Previous studies have utilized neural networks based on animal and plant cells to enhance robot movement and environmental responsiveness. However, maintaining these cells in artificial environments can be challenging and requires extensive care. The researchers in this study focused on using a more robust non-animal system based on fungi, which transmit information through electrical signals similar to animals.

Fungi create mycelial networks to transport nutrients, detect signals, and respond to environmental cues, making them resilient and less susceptible to contamination compared to animal cells. The researchers built two robots—one with independent arm movements and the other with forward-backward motion—and integrated the Eryngium mushroom fungus into their control boards to observe natural electrical signals and responses to stimuli.

By growing the fungi on the robot’s control interface and analyzing the bioelectrical signals, the researchers discovered that the network effectively controlled the robot’s functions. They also observed the fungus’s response to different light stimuli, leading to the conclusion that fungal biohybridization could revolutionize robotics with its adaptability and sensory capabilities.

The researchers conducted experiments to test the robot’s reaction to ultraviolet light, showcasing the fungus’s ability to control the robot’s movements solely through natural electrical signals. They proposed that fungal biohybridization offers a promising avenue for advancing robotics by leveraging fungi’s resilience and sensory capabilities for improved adaptability and reliability.

Fungal threat highlighted by Valley fever outbreak at California music festival

summary

  • California has seen an increase in cases of valley fever, a fungal infection, in recent years.
  • Fourteen confirmed cases among people who attended or worked at a music festival in the state are one example of the threat the bacteria poses.
  • Climate change is creating more opportunities for a fungus called Coccidioides to thrive.

Valley fever breaks out among attendees Infections among workers at an outdoor music festival in California's Central Valley highlight the growing threat of fungal infections.

Fourteen people who traveled to Bakersfield to attend or work at the Lightning in a Bottle festival in May have tested positive for valley fever and developed symptoms, the California Department of Public Health told NBC News on Thursday. At least three people have been hospitalized.

“About a week after I got back from the festival, I got really bad body aches and fever,” said Eric Mattson, 33, a musician from San Luis Obispo who attended this year's festival after testing positive for valley fever last month.

The condition progressed to joint pain, difficulty moving and night sweats. “I would wake up two or three times in the night drenched in sweat. I had to change my bedding and pyjamas in terrible pain. It was really bad,” Mattson said.

The bacteria that causes valley fever, Coccidioides, thrives in hot, dry climates, so most cases have been seen in Arizona and California. Climate change is creating more opportunities for the bacteria to grow, leading to an increase in valley fever cases in California.

“The number of reported valley fever cases has been particularly high in 2023 and 2024, which may be related to heavy rains in the winter of 2022-2023 following several years of drought,” the health department said in a statement.

The number of annual cases in California has increased from fewer than 1,000 in 2000 to more than 9,000 in 2019. Recent reports from state health departmentsThere have been 5,370 suspected or confirmed cases so far this year.

San Joaquin County has already seen more than 200 suspected and confirmed cases combined this year, 47 overall last year and 59 so far in 2022.

Valley fever is not transmitted from person to person. Rather, it infects the lungs by inhaling spores in dust or soil. The name comes from the San Joaquin Valley, where Coccidioides was found.

Mattson said he hasn't been contacted by the California Department of Public Health, which has not released the names of the 14 people who have been confirmed to be infected, so it's unclear if Mattson is among them. NBC News has reviewed Mattson's medical records, which show he tested positive.

Mattson estimated he lost 20 pounds in four to five weeks.

He suspected valley fever, having heard reports of some festival-goers being infected in the past, but was initially diagnosed with pneumonia. Eventually, his family doctor ordered a blood test, which came back positive early last month.

Mattson's situation is common, says Dr. Geeta Sivasubramanian, an assistant professor of clinical medicine at the University of California, San Francisco, Fresno: “Patients with valley fever are often misdiagnosed with bacterial pneumonia.”

That's because many doctors don't recognize the disease, test for it too early, or confuse it with other respiratory infections, she says — errors that can lead to patients receiving unnecessary antibiotics instead of the appropriate antifungal medication.

About 60% of people with valley fever have no symptoms, but some may experience symptoms such as cough, fatigue, fever, shortness of breath, night sweats, muscle and joint pain, and a rash on the legs and upper body. People with diabetes, weakened immune systems, and pregnant women are more susceptible to severe lung infections. In very rare cases (about 1%), the lung infection can spread to the bones, joints, and brain, becoming life-threatening.

An ideal environment for spreading Valley Fever

Sivasubramanian said he wasn't surprised by the concentration of cases among the more than 20,000 people attending the music festival.

“We live in a valley fever endemic area so anyone who visits the area or lives in the area is at risk,” she said.

In the Central Valley, heavy winter rains encourage the growth of the fungus in the soil, then as temperatures rise and the soil dries, dust carries the spores into the air.

Activities that kick up large amounts of dust, such as construction and agriculture, increase the risk of exposure. In 2014, the U.S. Centers for Disease Control and Prevention stated: Five confirmed and five suspected cases of valley fever were linked. Dry and dusty environment on outdoor film set.

Dr. Arturo Casadevall, chair of the department of molecular microbiology and immunology at the Johns Hopkins Bloomberg School of Public Health, said “Lightning in a Bottle” appears to have come to the right place at the right time.

“You need two things: a spore cloud and a human,” he said.

Mattson said high winds during the festival stirred up dust near some of the stages and in the campgrounds where many attendees stayed.

“When you have a lot of people dancing, it definitely kicks up a lot of dust,” he said.

Valley fever may be spreading to new areas

Climate change is bringing increased rainfall and warmer temperatures, which provide better conditions for the fungus to thrive. It may also lead to more frequent and intense wildfires. Transporting spores to the surrounding area.

Outside of California and Arizona, 2019 Survey It's estimated that valley fever may already be endemic in certain counties in 10 other states, stretching as far east as Kansas and Oklahoma.

“As the desert expands, we're going to see cases outside of the historic areas,” Casadevall said.

Some researchers suspect that climate change may be altering rodent migration patterns, helping the fungus spread, but others don't think that's the case in general. 2022 Survey Coccidioides has been detected in rodents in Kern County, home of the Lightning in a Bottle festival.

Mattson said she doesn't regret attending the festival, but wants people in the community to know about the disease and its symptoms.

“If you've been in the valley or been anywhere where there's a lot of dust in the air, we really want to encourage people to get tested,” he said.

Survival of Endangered Frogs Boosted by Winter Sauna Treatment for Fungal Disease

Green and gold bell frogs in an artificial hotspot shelter

Anthony Waddle

One of Australia’s most endangered amphibians can fight off a deadly fungal infection with the help of a naturally heated shelter that researchers are calling a “frog sauna.”

The disease, chytridiomycosis, has wiped out about 100 species of frogs, toads and salamanders worldwide.

Green and gold bell frog (Litoria aureaThe fungus was once widespread along the south-eastern coast of Australia, but its range has shrunk by 90 percent, and although other factors such as habitat loss are also at play, chytrid is thought to be the greatest threat to the endangered species.

It has long been known that warm temperatures suppress fungal infections, and many frog species, including the Japanese bush frog, are susceptible to the disease in winter when it’s hard for them to stay warm, especially when it’s hard to find a warm place.

To learn more, Anthony Waddle The researcher, from Macquarie University in Sydney, and his colleagues studied two groups of captive frogs that were intentionally infected with chytridiomycosis over the winter.

The first group was provided with bricks with holes in them in an unshaded greenhouse shelter where temperatures rose to nearly 40°C (104°F), while the second group was provided with bricks in a shaded greenhouse shelter where temperatures rose to 35°C (95°F).

Frogs that were given warmer shelter had 100 times fewer chytrid spores on their skin than other groups.

Although chytrid has difficulty growing above 28°C (82°F), warmer temperatures appear to activate the frogs’ immune systems, Waddle said.

“Using shelter to survive is like a vaccination for the frogs,” Waddle says, “and we’ve shown that firefly frogs can develop resistance after heat has cleared their infection, potentially making them 22 times more likely to survive future infections in cold environments.”

Although the researchers have only tested the shelter on one species at this stage, they believe the technology could be used with other animals threatened by chytrid fungus, as long as they seek out natural warmth when it’s cold. Waddle says there are at least six Australian animal species that could benefit from the technology.

Importantly, these thermal shelters are easy and inexpensive to set up: “All you need is a small vegetable greenhouse from the hardware store and a few bricks, and it will only cost about $60-70. [Australian] “It will cost a few hundred dollars to build,” Waddle said, “and I can envision people putting them in their backyards to help the frogs through the winter.”
