Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million regulatory DNA sequences that act like genetic switches, controlling when and how genes are activated. These sequences, known as conserved non-coding sequences (CNSs), were detected using a new computational tool called Conservatory.

Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found to spread across moist surfaces by fermenting sugars and creating tiny fluid currents that carry them forward — a newly identified behavior researchers call “swashing.” In another study, a different group of bacteria was shown to control its movement using a microscopic molecular “gearbox” that can reverse direction like a biological snowmobile.

Researchers have uncovered a molecular trick used by hornwort plants that could help future crops capture carbon dioxide more efficiently. A unique protein feature called RbcS-STAR causes the key photosynthesis enzyme Rubisco to cluster into dense compartments, helping it work more effectively. When scientists added this feature to other plants, Rubisco reorganized in the same way. The finding raises the possibility of engineering more efficient photosynthesis into major crops.

Researchers have created a method called optovolution that uses light to guide the evolution of proteins with dynamic behaviors. By engineering yeast cells so their survival depended on proteins switching states at the right time, scientists could rapidly select the best-performing variants. The technique produced new light-sensitive proteins that respond to different colors and improved optogenetic systems. It even evolved a protein that behaves like a tiny logic gate, activating genes only when two signals are present.

Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that mitochondria—the cell’s energy generators—can actively pull oxygen away from chloroplasts, the structures responsible for photosynthesis. This previously unknown interaction suggests mitochondria can effectively “drain” oxygen inside plant cells, altering photosynthesis and the production of reactive molecules that help plants respond to stress.

Scientists have uncovered a crucial weakness in the malaria parasite that could open the door to new treatments. Researchers identified a protein called Aurora-related kinase 1 (ARK1) that acts like a traffic controller during the parasite’s unusual cell division process, ensuring its genetic material is properly separated as it multiplies. When scientists switched off ARK1 in laboratory experiments, the parasite could no longer replicate correctly and failed to complete its life cycle in both humans and mosquitoes—effectively halting its ability to spread.

A famously resilient bacterium may be tough enough to survive one of the most violent events imaginable on Mars. In laboratory experiments designed to mimic the crushing shock of a massive asteroid impact, researchers squeezed Deinococcus radiodurans between steel plates and blasted it with pressures reaching 3 GPa (30,000 times atmospheric pressure). Even under these extreme conditions, a significant portion of the microbes survived.

Scientists in Brazil have transformed cocoa waste into a functional chocolate-infused honey packed with antioxidants and natural stimulants. Using ultrasound waves, they enhanced honey’s ability to pull beneficial compounds from cocoa shells—no synthetic solvents required. The process is considered green and sustainable, and the product could find its way into gourmet foods and cosmetics.

Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in a coordinated way throughout the body. About a quarter of cell types change in number over time, and many of these shifts differ between males and females. The research also highlights shared genetic “hotspots” that could become targets for anti-aging therapies.

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial protein called MurJ, which is essential for building the bacterial cell wall. High-resolution imaging shows these viral proteins lock MurJ into a single position, stopping cell wall construction and leading to bacterial death.

Scientists at UC Berkeley have discovered a microbe that bends one of biology’s most sacred rules. Instead of treating a specific three-letter DNA code as a clear “stop” signal, this methane-producing archaeon sometimes reads it as a green light—adding an unusual amino acid and continuing to build the protein. The result is a kind of genetic coin flip: two different proteins can emerge from the same code, influenced partly by environmental conditions.

Scientists at MIT have found compelling chemical evidence that Earth’s earliest animals were likely ancient sea sponges. Hidden inside rocks over 541 million years old are rare molecular “fingerprints” that match compounds made by modern demosponges. After testing rocks, living sponges, and lab-made molecules, researchers confirmed the signals came from life — not geology. The discovery suggests sponges were thriving in the oceans well before most other animal groups appeared.

Biomolecular condensates were long believed to be simple liquid blobs inside cells. Researchers have now uncovered that some are actually supported by fine protein filaments forming an internal scaffold. When this structure is disrupted, cells fail to grow and divide properly. The discovery suggests scientists may one day design drugs that target condensate architecture to fight cancer and neurodegenerative disease.

Researchers are engineering bacteria to invade tumors and consume them from the inside. Because tumor cores lack oxygen, they’re the perfect breeding ground for these microbes. The team added a genetic tweak that helps the bacteria survive longer near oxygen-exposed edges — but only once enough of them are present to trigger the change. It’s a carefully programmed biological attack that could one day offer a new way to destroy cancer.

Flea and tick medications trusted by pet owners worldwide may have an unexpected environmental cost. Scientists found that active ingredients from isoxazoline treatments pass into pet feces, exposing dung-feeding insects to toxic chemicals. These insects are essential for nutrient cycling and soil health. The findings suggest everyday pet treatments could ripple through ecosystems in surprising ways.

Deep inside a Romanian ice cave, locked away in a 5,000-year-old layer of ice, scientists have uncovered a bacterium with a startling secret: it’s resistant to many modern antibiotics. Despite predating the antibiotic era, this cold-loving microbe carries more than 100 resistance-related genes and can survive drugs used today to treat serious infections like tuberculosis and UTIs.

A giant virus discovered in Japan is adding fuel to the provocative idea that viruses helped create complex life. Named ushikuvirus, it infects amoebae and shows unique traits that connect different families of giant DNA viruses. Its unusual way of hijacking and disrupting the host cell’s nucleus offers fresh insight into how viruses may have influenced the evolution of the cell nucleus itself. The finding deepens the mystery of viruses—and their possible role in life’s biggest leap.

Life on Earth may have learned to breathe oxygen long before oxygen filled the skies. MIT researchers traced a key oxygen-processing enzyme back hundreds of millions of years before the Great Oxidation Event. Early microbes living near oxygen-producing cyanobacteria may have quickly used up the gas as it formed, slowing its rise in the atmosphere. The results suggest life was adapting to oxygen far earlier — and far more creatively — than once thought.

Scientists studying a rock sample collected by NASA’s Curiosity rover have uncovered something tantalizing: the largest organic molecules ever detected on Mars. The compounds — decane, undecane, and dodecane — may be fragments of fatty acids, which on Earth are most often linked to life. While non-living processes like meteorite impacts can also create such molecules, researchers found those sources couldn’t fully explain the amounts detected.

Baker’s yeast isn’t just useful in the kitchen — it may also be built for space. Researchers found that yeast cells can survive intense shock waves and toxic chemicals similar to those on Mars. The cells protect themselves by forming special stress-response structures that help them endure extreme conditions. This resilience could make yeast a powerful model for astrobiology and future space missions.

Your gut is home to trillions of bacteria that constantly “sense” their surroundings to survive and thrive. New research shows that beneficial gut microbes, especially common Clostridia bacteria, can detect a surprisingly wide range of chemical signals produced during digestion, including byproducts of fats, proteins, sugars, and even DNA. These microbes use specialized sensors to move toward valuable nutrients, with lactate and formate standing out as especially important fuel sources.

Scientists have uncovered promising clues that compounds found in Aloe vera could play a role in fighting Alzheimer’s disease.

Scientists have cracked a key mystery behind spider silk’s legendary strength and flexibility. They discovered that tiny molecular interactions act like natural glue, holding silk proteins together as they transform from liquid into incredibly tough fibers. This same process helps create silk that’s stronger than steel by weight and tougher than Kevlar.

Plants make chemical weapons to protect themselves, and many of these compounds have become vital to human medicine. Researchers found that one powerful plant chemical is produced using a gene that looks surprisingly bacterial. This suggests plants reuse microbial tools to invent new chemistry. The insight could help scientists discover new drugs and produce them more sustainably.

A fast-aging fish is giving scientists a rare, accelerated look at how kidneys grow old—and how a common drug may slow that process down. Researchers found that SGLT2 inhibitors, widely used to treat diabetes and heart disease, preserved kidney structure, blood vessels, and energy production as the fish aged, while also calming inflammation. The results help explain why these drugs protect kidneys and hearts so reliably in people, even beyond blood sugar control.

Scientists have uncovered how cannabis evolved the ability to make its most famous compounds—THC, CBD, and CBC—by recreating ancient enzymes that existed millions of years ago. These early enzymes were multitaskers, capable of producing several cannabinoids at once, before evolution fine-tuned them into today’s highly specialized forms. By “resurrecting” these long-lost enzymes in the lab, researchers showed how cannabis chemistry became more precise over time—and discovered something unexpected: the ancient versions are often more robust and easier to work with.

Scientists are taking a closer look at monk fruit and discovering it’s more than just a sugar substitute. New research shows its peel and pulp contain a rich mix of antioxidants and bioactive compounds that may support health. Different varieties offer different chemical profiles, hinting at unique benefits. The work could shape how monk fruit is used in future foods and supplements.

Researchers studying cyanobacteria from hot springs in Thailand have discovered a new natural UV-blocking compound with impressive antioxidant power. Unlike conventional sunscreens, it’s biocompatible and potentially safer for both people and the environment. The molecule is produced only under UV and salt stress and uses a unique biosynthetic pathway never seen before. This could help drive a new generation of eco-friendly sunscreens and skincare products.

Some antibiotics stop bacteria from growing without actually killing them, allowing infections to return later. Scientists at the University of Basel created a new test that tracks individual bacteria to see which drugs truly eliminate them. When tested on tuberculosis and other serious lung infections, the method revealed big differences in how bacteria tolerate treatment. The findings could lead to more precise therapies and better predictions of treatment success.

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing how genome structure changes from cell to cell and over time. These insights reveal why many disease-linked mutations outside genes can still cause harm. The findings could speed up the discovery of genetic risks and inspire new ways to target diseases.

Not all microbes are villains—many are vital to keeping us healthy. Researchers have created a world-first database that tracks beneficial bacteria and natural compounds linked to immune strength, stress reduction, and resilience. The findings challenge the long-standing obsession with germs as threats and instead highlight the hidden health benefits of biodiversity. This shift could influence everything from urban design to environmental restoration.

Spruce bark beetles don’t just tolerate their host tree’s chemical defenses—they actively reshape them into stronger antifungal protections. These stolen defenses help shield the beetles from infection, but one fungus has evolved a way to neutralize them. By detoxifying the beetles’ chemical armor, the fungus can successfully invade and kill its host. The discovery sheds light on an unseen forest arms race and may improve biological pest control.

UBC Okanagan researchers have uncovered how plants create mitraphylline, a rare natural compound linked to anti-cancer effects.

The discovery could make it far easier to produce mitraphylline and related compounds sustainably. It also highlights plants as master chemists with untapped medical potential.

Old military air samples turned out to be a treasure trove of biological DNA, allowing scientists to track moss spores over 35 years. The results show mosses now release spores up to a month earlier than in the 1990s. Even more surprising, the timing depends more on last year’s climate than current spring conditions. It’s a striking example of how fast ecosystems are adjusting to a warming world.

Researchers have uncovered that the body uses different molecular systems to sense cold in the skin versus internal organs. This explains why surface chills feel very different from cold experienced deep inside the body.

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These signals could help drive ion transport and explain key biological functions. The work may also guide the design of intelligent, bio-inspired materials.

Scientists discovered a small protein region that determines whether plants reject or welcome nitrogen-fixing bacteria. By tweaking only two amino acids, they converted a defensive receptor into one that supports symbiosis. Early success in barley hints that cereals may eventually be engineered to fix nitrogen on their own. Such crops could dramatically reduce fertilizer use and emissions.

Researchers successfully implanted a genetically modified pig liver into a human, proving that such an organ can function for an extended period. The graft supported essential liver processes before complications required its removal. Although the patient ultimately passed away, the experiment demonstrates both the potential and the complexity of xenotransplantation. Experts believe this could reshape the future of organ replacement.

Ant pupae that are fatally sick don’t hide their condition; instead, they release a special scent that warns the rest of the colony. This signal prompts worker ants to open the pupae’s cocoons and disinfect them with formic acid, stopping the infection before it can spread. Although the treatment kills the sick pupa, it protects the colony and helps ensure its long-term survival. Researchers found that only pupae too sick to recover send this scent, showing just how finely tuned the colony’s early-warning system is.

Scientists found that adult bristleworm eyes grow continuously thanks to a rim of neural stem cells similar to those in vertebrate eyes. This growth is surprisingly regulated by environmental light via a vertebrate-like c-opsin. The discovery reveals deep evolutionary parallels between distant species and raises questions about how light shapes nervous systems beyond vision. It hints at hidden complexity in creatures long assumed to be simple.

Researchers discovered why bird flu can survive temperatures that stop human flu in its tracks. A key gene, PB1, gives avian viruses the ability to replicate even at fever-level heat. Mice experiments confirmed that fever cripples human-origin flu but not avian strains, especially those with avian-like PB1. These findings highlight how gene swapping could fuel future pandemics.

By boosting a natural compound in the plant, the wheat triggers bacteria to form biofilms that enable nitrogen fixation. This breakthrough could cut fertilizer use, reduce pollution, and increase yields. It also offers huge potential savings for farmers worldwide.

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at different points, researchers can now watch damage flare up, track repair proteins rushing to the site, and see the moment the DNA is restored. Built from a natural protein that binds gently and briefly to damaged DNA, the sensor offers a true-to-life view of the cell’s internal emergency response.

Worker bees stage coordinated revolts when viral infections weaken their queen and lower her pheromone output. This disruption drives many of the queen failures that beekeepers struggle with today. Field trials show that synthetic pheromone blends can prevent untimely supersedure, opening a path to more stable hive management.

The model includes the full mix of cells and signals needed for blood production and even maintains this process for weeks. It could transform how scientists study blood cancers and test new drugs. In the future, it may support more personalized treatment strategies.

Massive Sargassum blooms sweeping across the Caribbean and Atlantic are fueled by a powerful nutrient partnership: phosphorus pulled to the surface by equatorial upwelling and nitrogen supplied by cyanobacteria living directly on the drifting algae. Coral cores reveal that this nutrient engine has intensified over the past decade, perfectly matching surges in Sargassum growth since 2011. By ruling out older theories involving Saharan dust and river runoff, researchers uncovered a climate-driven process that shapes when and where these colossal seaweed mats form.

Researchers have sequenced the oldest RNA ever recovered, taken from a woolly mammoth frozen for nearly 40,000 years. The RNA reveals which genes were active in its tissues, offering a rare glimpse into its biology and final moments. Surprisingly, the team also identified ancient microRNAs and rare mutations that confirm their mammoth origin. The finding shows that RNA can endure millennia—reshaping how scientists study extinct species.

Scientists studying aging found that sensory inputs like touch and smell can cancel out the lifespan-boosting effects of dietary restriction by suppressing the key longevity gene fmo-2. When overactivated, the gene makes worms oddly indifferent to danger and food, suggesting trade-offs between lifespan and behavior. The work highlights how deeply intertwined the brain, metabolism, and environment are. These pathways may eventually be targeted to extend life without extreme dieting.

Scientists at EPFL have unraveled the mystery behind why biological nanopores, tiny molecular holes used in both nature and biotechnology, sometimes behave unpredictably. By experimenting with engineered versions of the bacterial pore aerolysin, they discovered that two key effects, rectification and gating, stem from the pore’s internal electrical charges and their interaction with passing ions. The team even built nanopores that imitate brain-like “learning,” hinting at future applications in bio-inspired computing and ion-based processors.
