Creepy, futuristic ‘cyborg' beetles may help rescue victims of natural disasters, scientists say
Between bomb-detecting rats and medical-grade maggots, it's clear that one person's pest is another's savior. The latest member of this unlikely league of heroes is a remote-controlled beetle that could potentially be used to rescue victims of natural disasters, per a spine-tingling study published in 'Advanced Science.'
'It [the beetle] could be used in search-and-rescue missions as it could go into small nooks and crevices in a collapsed building to locate injured survivors,' said Dr. Thang Vo-Doan, a researcher at the University of Queensland in Australia who spearheaded the research, Phys.org reported.

These cybernetically-enhanced insects are then piloted remotely using video game controllers so they can access survivors following a mine or building collapse.

Why deploy one of the world's oldest lifeforms instead of seemingly more advanced bots? Vo-Doan explained, 'Beetles possess many natural gifts that make them the masters of climbing and maneuvering in small, complex spaces such as dense rubble, that are difficult for robots to navigate.'
'Our work harnesses these gifts and adds programmable controls that allow for precise directional guidance, without affecting the lifespan of the beetle,' he added.

'If people have been trapped under an extensive amount of rubble, you want to be able to find them as quickly as possible and start planning how to get them out,' said Vo-Doan. He said he hoped the beetles would be able to 'easily move through chaotic environments to pinpoint a person's exact location, provide clues to any injuries, and give rescuers a picture of what needs to be done to free them.'
Researchers hope to test the tech in a real-life rescue situation within five years.
This is not the first time scientists have trialed using cyborg bugs as emergency responders. In 2014, researchers at North Carolina State University turned common cockroaches into remote-controlled biobots – bionic rescuers that can locate people trapped in rubble by using microphones.
'The goal is to use the biobots with high-resolution microphones to differentiate between sounds that matter – like people calling for help – from sounds that don't matter, like a leaking pipe,' said Alper Bozkurt, an assistant professor at the university.

Tiny cyborg beetles are built to save lives in real emergencies
In a groundbreaking fusion of nature and technology, researchers at the University of Queensland have developed remote-controlled beetles equipped with tiny, removable backpacks that could drastically reduce the time it takes to locate survivors in disaster zones. Also known as cyborg beetles, these hybrid helpers are part of an ambitious project to improve emergency response in situations like building collapses, earthquakes or industrial explosions. By combining natural mobility with simple controls, researchers are developing a faster, more flexible way to reach people in hard-to-access areas. The team's innovation involves fitting darkling beetles, or Zophobas morio, their scientific name, with microchip backpacks that deliver small electrical signals to guide their movement. These signals stimulate either the beetle's antennae or their hardened forewings, prompting them to turn, stop or climb. The researchers even demonstrated real-time control using a standard video game controller. Robots at this scale still struggle with climbing vertical surfaces and navigating uneven terrain. These beetles, on the other hand, are naturally built for it. Their footpads and sensory systems let them crawl through narrow cracks and over rubble. This makes them well-suited for the unpredictable conditions found in disaster zones. Beetles were chosen for their strength, agility and resilience. Despite their small size, they can carry equipment nearly equal to their own body weight, which makes them an ideal platform for compact sensors and control systems in tight, dangerous spaces. Unlike custom-built robots, these beetles don't need motors or gears to move. Their natural ability to climb, squeeze and maneuver through tight spaces eliminates the need for complex mechanical systems. The programmable backpack simply adds directional control without harming the beetle or shortening its lifespan. The result is a biological tool that can access places humans and machines cannot. This could help reduce the time it takes to locate survivors in critical situations. Researchers are now working to integrate miniature cameras and compact power systems to make the beetles even more effective. The goal is to create a lightweight, mobile, and affordable tool that can deliver real-time information from inside collapsed structures and hazardous environments. The team hopes to test the system in a live emergency simulation within the next five years. If successful, cyborg beetles could become a valuable part of urban response efforts around the world. Researchers are proving that cyborg beetles could play a real role in saving lives. By guiding beetles through tight, dangerous spaces using tiny backpacks and simple controls, scientists are exploring a low-cost and high-impact way to locate survivors where robots and humans can't go. The technology is still in development, but the potential is clear, especially in situations where every second counts. Would you trust a rescue led by a cyborg beetle?

Scientists make revolutionary breakthrough that could solve major problem with how we grow food: 'Could have big, positive agricultural implications'
Researchers have identified an enzyme that could help reduce harmful runoff and fertilizer usage in food production. The finding has the potential to reduce heat-trapping pollution and prevent deadly algal blooms while saving farmers money, which means a healthier environment and cheaper food. A team from Michigan State University detailed the findings in a review article published in Applied and Environmental Microbiology, and the work was further summarized in a release posted to "A significant amount of nitrogen fertilizer is lost because it's converted to a form that's easily leached away," Krystina Hird, the review article's lead author, said, per the release. "If we retain more of that nitrogen in the soil, it could have big, positive agricultural implications." Nitrogen is essential to all life on Earth. Plants require nitrogen to build amino acids, proteins, and chlorophyll, according to Sound Agriculture. More nitrogen in the soil means healthier plants and larger crop yields, which allows for more food to be grown on less land. Although 78% of the atmosphere is made up of nitrogen, plants can only access nitrogen through soil. Plants rely on tiny microbes in the ground to transform atmospheric nitrogen into forms they can use, per Sound Agriculture. For decades, farmers have supplemented this natural process by adding nitrogen fertilizers to the soil. Ammonium is one of the best forms of nitrogen for agricultural uses because it is positively charged, causing it to bond with negatively charged soil, per the summary. However, certain soil microbes transform ammonium into nitrite, which is negatively charged. Like the negative poles on two magnets repelling one another, nitrite and soil do not bond, making nitrite more susceptible to being washed away in runoff, explained That's where the breakthrough enzyme, known as NrfA, comes in. NrfA turns nitrite into ammonium, and, while it is not the only enzyme to do so, it is by far the most efficient, per the summary. What is stopping you from upgrading to a heat pump system? The cost of installation I live in a cold area I don't know enough about it I already have one Click your choice to see results and speak your mind. Though this discovery is technical, it potentially could benefit billions of people every single day. Nitrogen runoff, also known as nutrient pollution, occurs when water from fertilized agricultural lands washes into bodies of water, including rivers, lakes, and oceans. The influx of nutrients allows algae to flourish, according to the Environmental Protection Agency. These algae consume oxygen from the water, creating low-oxygen dead zones where fish and other wildlife cannot survive. Nitrogen runoff has negative consequences for human health as well. According to the NIH, nitrogen runoff contaminates both public drinking water sources and private wells. Its presence in drinking water has been linked to multiple cancers, hypothyroidism, and blue baby syndrome. Lowering the amount of nitrogen fertilizer farmers use would reduce these public health risks and prevent dead zones while also combating heat-trapping pollution. All told, the global food production system accounts for a whopping 35% of the planet-heating pollution humans generate. Fertilizer production, transportation, and application alone make up a jaw-dropping 5% to 6%, according to the University of Illinois Urbana-Champaign. Producing and using less nitrogen fertilizer would be a big step toward lowering the pollution our global food supply produces. That all of these benefits could possibly come from just one enzyme in the soil shows the incredible interconnectedness of our world and how delicate the balance is that we must maintain. The next step for the team of Michigan State researchers will be to better understand the details of how the NrfA enzyme works. "We're trying to get really specific and nitty-gritty," Hird said, per the summary. "It's going to be like performing a delicate surgery." The same could be said for addressing the many environmental challenges we currently face. Thankfully, discoveries like the NrfA enzyme give us hope that we can rise to meet them.

New study finds that koalas spend 10 minutes a day in this deadly spot
Even though koalas are only on the ground for 10 minutes a day, experts have found that those few minutes are by far the most deadly. A new study has revealed that two thirds of the 10 recorded koalas die during the brief period they spend on the ground. Although the recorded koalas only spent about 10 minutes on the ground each day, two-thirds of them died in that tiny amount of time—usually from vehicle collisions or dog attacks. The research was led by the University of Queensland PhD student, Gabriella Sparkes, who explained, 'Koalas are mostly tree-dwelling, but due to extensive land clearing, they're increasingly forced to travel on the ground, which puts them at a serious risk of injury and death.' The koalas–an endangered species in Australia–were fitted with GPS collars to monitor their movements, and it was revealed that the marsupials spent just 1% of their daily life on the ground–that's alongside the 20 hours usually reserved for sleep. Researchers behind the study are now pushing for conservation efforts to aim primarily at reducing the amount of time that koalas need to spend on the ground. Sparkes added, 'If we can identify the kinds of trees or habitat conditions that encourage koalas to remain in trees for longer, we may be able to design or manage landscapes in ways that reduce the need for ground travel.'
