Fireflies are hard to miss in Michigan. What to know as they light up backyards
Perhaps once collected in a jar or observed from the palm of your hand, fireflies are curious creatures that communicate via a yellow glow. They are especially chatty on hot summer nights. Fireflies (or lightning bugs) prefer hot and humid weather. They emerge when temperatures become warm typically around May or mid-June. Residents can expect to see more fireflies over the summer after a mild winter and a rainy spring, according to the Farmers' Almanac. At dusk or later in the night they become active creating quite the spectacle. Their ability to create light is credited to a process called bioluminescence. Fireflies can control the chemical reaction inside their light organ located in their lower abdomen. Species of jellyfish, shrimp, shark, squid and other marine animal share the same ability. According to NC State University, fireflies use bioluminescence to intimidate predators, attract a mate and even communicate. In North America, there are hundreds of firefly species with three main groups, called photinus, pyractomena and photuris, based on Mass Audubon, and they vary in size and even the color of their light. For example, pyractomena fireflies flash an amber color, while photinus flash a yellow-green. Though fireflies are frequent in Michigan this summer, their populations overall are threatened due to habitat loss and light pollution, according to Xerces Society for Invertebrate Conservation. As fireflies continue to flash, sparkle and possibly inspire a child-like wonder, here's more on these species in Michigan: Why do fireflies light up? Fireflies communicate via flashes of their light to attract mates, deter predators or claim territory, according to Firefly Conservation and Research. Flashes are unique to firefly species, though the photinus carolinus fireflies flash in synchronization — a rare, temporary behavior that occurs during the summertime, and previously observed in many national parks. "Each species of firefly has its own pattern. Many fireflies look similar, so these flash patterns help to identify particular firefly species," Mass Audubon said. Both male and female fireflies have the ability to create light, though to tell them apart, males have a larger light organ covering two segments of their bodies, while females' light organs are typically smaller. Are fireflies a beetle? Yes, fireflies are beetles and they belong to the insect order called coleoptera and the insect family called Lampyridae — which means "to shine," in Greek, according to Michigan State University's Extension. Like other species of beetles, fireflies have two pairs of wings with a shell-like covering to protect their wings, so while they are flying, their shell is raised upward to let their wings flap freely. Do fireflies bite? No, fireflies do not bite or sting humans. However, they may become a nuisance if a few accidently enter your house. According to pest control company Orkin, to keep fireflies out of your home, remove or reduce outdoor lightning so they only have their bioluminescence to rely on. What do fireflies eat? Fireflies are a predatory beetle and eat other insects like snails, slugs or worms. They go through a lengthy life cycle (up to 3 years) and spend most of their life in the larval stage underground, and at this stage they are "eating machines," according to MSU's Extension. Not only do they have an appetite, but they have a fierce hunting strategy. According to Firefly Atlas, they inject a paralyzing neurotoxin into their prey then emit a digestive enzyme to liquefy them before eating. Why are firefly populations going down? According to Firefly Conservation and Research, the main factors disrupting firefly numbers are habitat loss and light pollution. "Scientists have observed that synchronous fireflies get out of synch for a few minutes after a car's headlights pass," the research-based organization said. "Light from homes, cars, stores, and streetlights may all make it difficult for fireflies to signal each other during mating — meaning fewer firefly larvae are born next season," the organization said." Here are a few ways to help steady their populations from your backyard: Turn off outdoor lighting Create a firefly habitat Avoid using pesticides or weed killers Plant native trees, like pine trees In addition, people may report their firefly sightings to help track their distribution nationally. Firefly Atlas, a conservation organization, features a tracker for members (after creating an account) to submit their sightings.

It's Alive! Iris Van Herpen's Latest Innovation? A Dress Made From 125 Million Bioluminescent Algae
As fittings were underway on Saturday, Van Herpen and her latest collaborator, Chris Bellamy, gave Vogue a preview of the creation. Like some kind of otherworldly specimen on display, the dress and pant ensemble hung inside a box carefully controlled with light—exactly the wavelength where the algae are found 50 meters below sea level—and humidity, with a cloud of cold steam pooling around the base. Photo: Molly SJ Lowe/ Courtesy of Iris Van Herpen Photo: Molly SJ Lowe/ Courtesy of Iris Van Herpen In this daylight setting, the dimensional pattern was not illuminated, but milky white with a trace of blue; an imperfect comparison might be glow-in-the-dark stickers that have a greenish tinge. Like humans, pyrocystis lunula need 'sleep' and have their own light cycles like our Circadian rhythms. In the wild, they emit light in response to movement and/or when they sense predators. No word yet who Van Herpen is casting to wear the look or how the model will provoke the flash of light. Yet with Van Herpen standing on one side of the box and Bellamy on the other, they explained how they first connected in February, some two years after Bellamy began his research in French Polynesia (he still travels there while also working in France, the UK and Amsterdam, where Van Herpen is based). Once they agreed to advance on the project, Bellamy got to work on the algae farm—essentially a chamber of controlled light where the microorganisms grow in seawater, doubling in quantity every two weeks. After enough time, there was 20 liters of algae—a little more than a half-filled bathtub. Going from a liquid state to a solid that could be injected into Van Herpen's custom molds involved transferring the algae to a seaweed nutrient gel—some 50 were tested to arrive at the right texture, color, and overall balance—and coating the forms with a protective membrane that's breathable and allows them to live and glow. In total, this turned into a roughly 35-step process with support from the University of Amsterdam and the Francis Crick Institute for biomedical research. After significant trial and error, not to mention attaching the pattern to an illusion mesh second skin, they said they reached the successful outcome—'it worked,' said Bellamy—about a month ago. The garments are now stored according to precisely controlled conditions that correspond to the algae's native environment, such as temperature, light, humidity and rhythm. The organisms can continue to mate and reproduce inside the garment forms, making the dress brighter and brighter. As for an odor, Bellamy replies, 'No, you can just smell the seawater.'

This Spanish biotech startup makes plants glow in the dark – and Dubai is next
Pablo Vidarte has spent the last decade perfecting something that sounds like pure science fiction: making ordinary plants glow in the dark. Now the Spanish entrepreneur is bringing his experimental landscaping technology to Dubai, targeting villa owners with promises of gardens that light themselves. It might sound fantastical, but Vidarte's Barcelona-based company Bioo has deployed variations of the technology across three different approaches. The company already has installations in Riyadh using phosphorescent compounds, though specific locations were not disclosed, with brightness levels remaining limited to ambient lighting. Resort guests in Ibiza experience the world's first biotechnological botanical garden with interactive plant installations. Meanwhile, natural bioluminescent fungi illuminate spaces without any modification whatsoever. 'In Dubai, we are making villas,' Vidarte told Arabian Business on the sidelines of GBB's Real Estate Development Summit in Lisbon, Portugal. 'Two, three months.' Biotech cities of the future The technology behind Bioo Lumina – the company's bioluminescent landscaping system – represents what Vidarte calls 'a leap forward in the lighting of urban green areas,' offering three distinct solutions that address different regulatory environments and brightness requirements. Bioo's approach splits into three categories: Natural solutions use over 58 species of bioluminescent fungi without modification, though light output remains dim. The Compound approach applies phosphorescent substances that plants absorb within 24 hours to eventually create consistent nighttime illumination while still maintaining normal biological functions. 'The compound itself doesn't genetically modify the plant. It grows with it,' Vidarte explained. 'The most important thing is that it doesn't affect its offspring.' A third Genetic approach remains in development, engineering plants to produce luciferase naturally, though this faces regulatory approval challenges across most markets. Bioo's technology has moved from laboratory experiments to real-world installations, though questions remain about long-term commercial viability. The company reports installations in Barcelona, Ibiza, and Riyadh, with varying scales and applications. The largest project appears in Medina, Saudi Arabia, where a luxury resort features 120,000 square metres of luminescent plants arranged in star constellation patterns. The installation reportedly cost over €2 million ($2.35 million), though returns on investment remain undisclosed. 'It looks like a mirror, and it's super cool. I mean, it's like having a lake reflecting the stars, but without water. Just, luminescent plants.' In Ibiza, the company operates what it describes as a biotechnological botanical garden featuring glowing plants and interactive installations where visitors trigger musical sequences by touching vegetation. The facility includes plant-activated systems that DJ David Guetta used for a 2018 performance. Founded in 2015, Bioo has positioned itself as a leader in what Vidarte believes will be the next technological revolution. 'The next revolution humanity will see is the biotech one,' he said, pushing back against the current AI obsession sweeping Silicon Valley and beyond. The company's broader mission extends far beyond glowing plants. Bioo has developed biological batteries capable of generating energy from soil decomposition, saving water, and absorbing CO₂. Their Bioo Panel technology can reduce irrigation needs by 50 per cent while regulating temperature by 4°C and absorbing 8kg of CO₂ per square metre. 'We've made sort of the mechanism that already is able to transform a park into an asset instead of a liability,' Vidarte explained. 'What if we could now reshape the lighting of the park?' The entrepreneur's vision of 'biotech cities' challenges conventional urban planning. These would be environments where buildings and infrastructure work symbiotically with nature, using biological processes to generate energy, purify air, and regulate temperature. 'We envision a greener future through a true symbiosis between nature and technology,' according to the company's mission statement. Bioo estimates that interaction with plants can increase people's well-being by more than 15 per cent, potentially extending life expectancy by 12 years. For all its science fiction appeal, Bioo faces practical challenges in scaling bioluminescent landscaping. Current brightness levels suit ambient lighting rather than high-intensity illumination, limiting applications to parks, gardens and entertainment venues rather than major roads requiring safety lighting. The phosphorescent compound approach requires annual maintenance as plants grow and dilute compound concentrations. Installation costs remain largely undisclosed, though industry estimates suggest approximately €19 (approx. $22) per square metre for large projects, potentially competitive with premium LED systems when factoring in zero electricity consumption. Bioo claims its bioluminescent technology can reduce lighting-related energy consumption by up to 80 per cent, though independent verification of these figures is not available. The company suggests additional benefits including air purification and carbon sequestration, though environmental scientists question the introduction of phosphorescent compounds into urban ecosystems. The breakthrough Vidarte's journey began in 2014 with a 3 AM breakthrough. 'At 3 AM I woke up and I said, shit, that's so cool that it needs to be done,' he said. Seven years of development followed before commercial launch in 2021, focusing on compounds ordinary vegetation could absorb naturally rather than genetic modification. 'I basically stayed in my own cave during several weeks [of] studying, learning. Then I created a team of volunteers – engineers and biotechs, from companies, universities,' he described of the early days. At 34, Vidarte has accumulated over 20 international awards including recognition from Google and the European Parliament, among others. His vision extends beyond novelty lighting into 'symbiotic architecture' where technology and nature actively support human well-being. 'If you woke up in a biotech city, the first thing you would do is touch a plant just to turn on the lights,' he explained. 'Afterwards, you would go to your living room and you would see that there are plants hanging from the ceiling just compensating heat, working as a natural air conditioner. You would go out and you would see in your city that even the street lights are powered with the very same ground that the water that is generated, even in Dubai, for example, from the very same desert, from the soil itself.' Plants, Vidarte said, have their own complex social structures. 'They communicate through sound and through the roots, and they even have wars and allies and a lot of geopolitics. There's a lot of geopolitics in plants.' The company's interactive installations tap into this plant communication, creating what Bioo calls 'living libraries' where touching plants triggers recorded human messages. 'It's like an evolutionary monument that depends on the human being and nature, and only one of these two fails, everything goes away.' Dubai's embrace of bioluminescent landscaping aligns with the UAE's Net Zero 2050 strategy and the emirate's reputation for architectural innovation. The city's growing luxury villa market increasingly competes on unique environmental credentials alongside traditional amenities. Vidarte declined to name specific Dubai clients but confirmed residential and commercial installations are already underway. The technology offers villa owners something genuinely novel – gardens that glow without grid electricity. However, this raises questions about maintenance costs and practical utility beyond aesthetic appeal. 'We're transforming the view of creating practical cities where you box yourself in concrete boxes, and where nature is just decoration outside. What if we could literally merge nature and technology?'

Our brains are glowing, and scientists want to figure out why
If you purchase an independently reviewed product or service through a link on our website, BGR may receive an affiliate commission. The human brain is a fascinating organ. Not only are we just starting to truly discover how the brain learns, but we're finding out even more new things about one of our body's most important pieces. For instance, according to new findings, the human brain is almost constantly glowing, and scientists have no idea why. But they want to find out. It's strange to imagine your brain emitting light, but almost everything in the world emits photons of some type, which means everything is emitting some type of light. However, most of the time this light is in a part of the spectrum that the human eye cannot see. Today's Top Deals Best deals: Tech, laptops, TVs, and more sales Best Ring Video Doorbell deals Memorial Day security camera deals: Reolink's unbeatable sale has prices from $29.98 When it comes to the human brain, researchers believe that the glowing seen within the brain may come from biomolecular reactions, which generate energy and thus create photons as a byproduct. As such, the more energy the tissue burns, the more of a glow it emits, which means the brain should glow brightest out of all the tissue found in our bodies. The authors behind a new study believe that the relationship between this bioluminescence and brain activity could hint at a deeper role for light to play in the brain. But this isn't exactly a new idea, either. Humans have been debating the role of biophotons in the human body, as well as the part they play in cellular communication, since the 1920s, at least. That's part of why the researchers behind this new study decided to pay so much attention to the brain. Upon closer inspection, they found that the brain does indeed glow thank to the production of photons when energy is generated. Additionally, they found that the presence of light is much greater when captured directly within a living brain, versus looking at a few cells on a petri dish. Of course, this still doesn't tell us the exact role that biophotons play in brain activity or cellular communication. But it does at least teach us a bit more about the brain, and give scientists another thread to follow as they search for deeper answers.

Volunteers sought to help survey glow worms in Cumbria
Volunteers are being sought to help survey for glow worms at a country estate. They will spend 10 weeks looking for the insects, which are beetles that use bioluminescence to attract mates, across the Lowther Estate near Penrith, Cumbria. The volunteers will be trained by experts from Manchester Museum to try and find glow worms, which are believed to be declining in insects are "voracious" predators of snail and slug populations, Lowther Conservation ecologist Elizabeth Ogilvie said. "[They help] maintain balance in our landscapes," she said. "They also contribute to soil health by cycling nutrients back into the ecosystem."Ms Ogilvie said their glowing signals which are vital for mating are often drowned out by artificial lights and their numbers appear to be declining across the country. The survey, which will be conducted in the evenings, will help scientists determine whether glow worms are present on the estate, assistant curator from Manchester Museum, part of The University of Manchester, Bethany Dean may provide an opportunity for long term monitoring on the site, she Ogilvie said no experience was necessary to volunteer – simply an "eagerness to help on summer evenings".
