Sauna frogs

The green and golden bell frogs are among many amphibian populations the world over threatened by chytrid fungus. But a new frog sauna in your backyard could save their lives.

The chytrid fungus, or more specifically, Batrachochytrium dendrobatidis (Bd), causes a disease called chytridiomycosis.

“For more than half of the amphibian species currently classified as Critically Endangered, disease is a primary cause. In fact, 80 percent of all amphibian extinctions recorded since the 1980s have been caused by the Bd chytrid fungus pandemic.

Today, Bd is directly threatening 600 species, with an additional 75 species in its path,” says Amphibian Ark.

Frogs seem to be hit the hardest, and the green and golden bell frogs of southwestern Australia are on the brink of extinction with the chytrid fungus spreading rapidly.

The fungus’ zoospores, once shed by an infected frog, can survive for weeks in water with the right temperature, searching for a new host.

After it latches onto a new, unsuspecting amphibian, it impacts the keratin skin layer. Frogs’ skin is imperative to their survival since they depend on its permeability for respiration, water balance and electrolyte balance.

Once the skin is taken over by the fungus, and these vital functions cease, it ultimately leads to heart failure.

So how do we fix the problem?

Well, we can’t get rid of the fungus, so conservation biologist Anthony Waddle is doing some award-winning recon by building the frogs a sauna.

The chytrid fungus thrives in cooler temperatures, so even a temperature of 28 degrees Celsius can help.

The theory has existed since 2013, when tree frog researchers in Australia noticed higher populations in areas with rocks or boulders that absorbed heat from the sun during daylight hours and hypothesized the frogs sheltered themselves around the warmth.

Waddle and his team decided to test the theory with a variety of sauna designs. The final design is a simple greenhouse shape with stacked masonry bricks covered in translucent plastic. The bricks have small holes for convenient entry and exit so our froggy friends can sauna with ease.

For this work, Waddle was awarded the 2025 Future for Nature Award. He will use the prize money to grow the impact via vaccines and engaging local councils and the public to build frog saunas. “I am so excited that our work is getting attention and that folks are passionate about helping our struggling frog populations,” Waddle tells KUST Review.

In the meantime the team has created simple how-to videos so that anyone can get involved. Though several greenhouse suppliers have posted the videos on their websites, the team hopes to get as many community members as possible to hop on board. The frogs will naturally seek out the sauna as they instinctually understand the benefits.

Ultimately, if you build it, they will come.

Natural peptides might guard
against COVID-19

Two of our body’s natural defensins, HNP2 and HD5, might be a secret weapon against COVID-19, a new study reveals. These tiny peptides (mini-proteins) are produced by the immune system against germs.

Researchers from the University of Missouri used advanced computer simulations to view the interactions between the COVID virus and the defensins. The results indicate that HNP2 and HD5 could attach themselves to the virus’ spike protein, blocking it from locking onto your cells.

The defensins are also found in the lungs and gut, common places COVID attacks, which means they’re already stationed at the front lines.

The research team thinks defensins could be turned into something like a nasal spray or pill to help keep viruses at bay in the future.

This is not a cure — but is an interesting look into how our biology may inspire the next advancement in antiviral treatments. Lab tests are to follow.

The study was published in The Microbe.

From pollution to power

A team of scientists in China has developed a way to turn methane and carbon dioxide, the two main drivers of global warming, into clean air while creating a useful fuel.

Converting these greenhouse gases into syngas, a useful blend of hydrogen and carbon monoxide using solar and wind electricity, not only reduces carbon emissions — it goes net-negative. This means the process removes more CO2 from the air than it adds.

Running electricity through a mix of nickel, which is good at helping chemical reactions along, and lanthanum oxide (Ni–La₂O₃), a rare Earth element, syngas is created without the need for hot furnaces or burning fossil fuels. The system works longer and more efficiently than anything previously attempted.

This research, published in Science Advances, can help fight climate change while producing valuable fuel that industries use to make chemicals, plastics and clean hydrogen.

Healthier cats,
healthier communities

Coco, an Arabian Mau kitten, was born on the streets of Abu Dhabi near Raha International School. Her infections were so severe her eyes were glued shut. She was also filthy and undernourished. But she was lucky to be rescued at just a few weeks old and find her forever home.

She is only one of an estimated 100,000-150,000 stray cats living on the streets in the UAE, and most aren’t so fortunate. But thanks to a new program being piloted in several Abu Dhabi communities, their luck may be about to change.

In 2025, Asteco, a real estate services company, was approached by Animal Welfare Abu Dhabi, a non-profit, to launch a pilot program in four compound communities in Abu Dhabi: Al Rayyana, Mamsha Al Saadiyat, Raha Gardens and Mayan. Rachel Shaw, CEO of Animal Welfare Abu Dhabi (AWAD), tells KUST Review that the Community Cat Care Program aims to provide care for the animals.

There are a number of reasons a program like this is needed. One of these, though it’s not the initiative’s main focus, is public health.

Uncared-for cats can carry a number of diseases and are more susceptible to feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV). These viruses weaken cats’ immune systems, making it difficult to fight off even more diseases.

Although it is possible for strays to acquire FeLV, “It is likely that the transmission from a mother to her kittens is the greatest source of infection,” says the MSD Veterinary Manual.

Some diseases carried by felines can be transmitted to humans, like cat scratch fever and toxocariasis.

Toxoplasmosis is another disease felines can carry.

It is transmitted through feces and can harm pregnant women, potentially causing birth defects or miscarriage. Transmission of this, however is incredibly rare. The Abu Dhabi Animal Shelter says exposure is “unlikely” through petting an infected cat as the parasite is not carried on their fur and the same goes for being scratched or bitten by one. “In the past, immunodeficient people and pregnant women were advised to avoid cats. However, the Center for Disease Control (CDC) now advises that this is not necessary,” the website reads.

Aside from the minimal risk to humans, these cats suffer greatly.

Among infectious diseases and painful skin conditions, street cats in the region also struggle due to a lack of food, water and basic veterinary care for illnesses and injuries, and ensuring the animals are taken care of is the primary concern of Animal Welfare Abu Dhabi and the Community Cat Care Program.

While they can be resourceful, many stray cats have been dumped by previous owners and don’t know how to care for themselves. The heat in the region amplifies problems when summer temperatures can reach 50 degrees Celsius.

The the Community Cat Care Program aims to solve or at least reduce these issues and ensure our cat population is cared for properly.

The initiative, still in the pilot phase, has placed feeding stations equipped with fresh food and water around the perimeters of the chosen communities.

Along with this is a TNVMR (trap–neuter–vaccinate–microchip–return) program.

“This approach is carried out by registered, trained and fully supported volunteers who are also residents of the respective communities,” Shaw says.

“These volunteers are responsible for humanely trapping and transporting community cats to our approved veterinary clinics.”

Spaying and neutering the cats contributes to their overall health.

Without this, cats are at increased risk of such life-threatening health issues as uterine infections and breast tumors in female cats and testicular cancer in males.

Un-neutered male cats are also more likely to acquire and spread FIV and FeLV, but as Shaw mentions, “FeLV is more likely to be found in an indoor multi cat household (unlicensed shelter or hoarder situation) than a community cat population.”

The program’s procedures protect the cats from disease and contribute to a better quality of life.

The process goes something like this:

    • Cats are humanely trapped and transported to approved veterinary clinics, where they are sterilized, vaccinated, microchipped and ear-tipped for identification before being returned to their original location.
  • During intake, every cat is checked for an existing microchip and ear tip. Owned cats are identified through their microchips and/or collars and are excluded from the TNVMR program.
  • To estimate the size of a community’s cat population, a ratio-based method considers human population density and the nature of the residential environment (such as apartment towers or villas). Scientific studies indicate that sterilizing at least 80 percent of the feline population achieves a meaningful reduction in breeding rates.
  • The program keeps detailed records of all cats processed. These figures support data analysis and outcome tracking.

“A pre-program qualitative survey was conducted, and it will be relaunched once the 80 percent sterilization threshold is achieved. This will allow measurable, tangible impact, such as changes in cat visibility, nuisance complaints and resident attitudes,” Shaw adds.

Additional metrics to be measured include:

  • Number of cats sterilized, with breakdown by gender.
  • Number of cats assisted for illness or injuries and type of illness/injury.
  • Number of cats assisted and removed from the community for adoption.
  • GPS locations of cats at the point of trapping — allowing accurate mapping of hot spots and investigation of causes (such as unaccounted-for feeding stations or backyard breeding).
  • Records of requests for community cat assistance, including type of support provided (from direct intervention to community-education efforts).
  • Number of cats already sterilized that have been health-checked, vaccinated, microchipped and registered to the program.
  • Number of cats euthanized on welfare grounds.

“We are using GPS data and mapping tools to visually track trapping locations and trends. As the program grows, we’re exploring further options for digital monitoring and data capture, but for now, our focus is on consolidating reliable baseline data from the pilot phase,” Shaw tells KUST Review.

The pilot will be re-evaluated when it reaches target thresholds, Shaw says.

Tiny tech, rapid antibody mapping

A recent research paper published in Nature Biomedical Engineering shares a new way to study how the immune system battles viruses, requiring only a drop of blood and producing results in under two hours.

The technique, called microfluidic electron microscopy (mEM), is like offering scientists an extremely sleek microscope on steroids that can expose how antibodies latch onto viruses like influenza, HIV and SARS-CoV-2.

The chip, which is the size of a fingernail, requires only a single drop of serum (less than 4 microliters) and 90 minutes to complete the analysis that used to take a week, including lots of prep like cutting up antibodies and purification. It’s like a mini-lab and ultra-zoom camera all in one.

The speed isn’t the only perk. The tool is also super smart, finding more binding sites on viruses than previous methods.

This offers a more complete picture of how the immune system responds to viruses and vaccines alike. The smaller samples make it a game-changer for vaccine development by tracking immune system responses over time.
