A large study has revealed that dozens of widely used chemicals can damage beneficial gut bacteria. Many of these substances, found in pesticides and everyday industrial products, were never thought to affect living organisms at all. When gut bacteria are stressed by these chemicals, some may also become resistant to antibiotics. The research raises new questions about how chemical exposure could be influencing human health behind the scenes.

A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act like molecular anchors. The work confirms these tags actively silence genes, settling a long-running scientific debate. This gentler form of gene editing could offer a safer way to treat Sickle Cell disease by reactivating a fetal blood gene. Researchers say it opens the door to powerful therapies with fewer unintended side effects.

CO2 can stimulate plant growth, but only when enough nitrogen is available—and that key ingredient has been seriously miscalculated. A new study finds that natural nitrogen fixation has been overestimated by about 50 percent in major climate models. This means the climate-cooling benefits of plant growth under high CO2 are smaller than expected. The result: a reduced buffer against climate change and more uncertainty in future projections.

Researchers have developed experimental compounds that make cells burn more calories by subtly tweaking how mitochondria produce energy. Older versions of these chemicals were once used for weight loss—but were banned for being deadly. The new approach fine-tunes the effect, allowing cells to burn extra fuel safely. If successful, this could pave the way for new obesity treatments with added health benefits.

One of the most complete human ancestor fossils ever found may belong to an entirely new species, according to an international research team. The famous “Little Foot” skeleton from South Africa has long been debated, but new analysis suggests it doesn’t truly match any known Australopithecus species. Instead, researchers say its unique mix of features points to a previously unidentified human relative, reshaping ideas about early human diversity.

Scientists have found a way to see ultrafast molecular interactions inside liquids using an extreme laser technique once thought impossible for fluids. When they mixed nearly identical chemicals, one combination behaved strangely—producing less light and erasing a single harmonic signal altogether. Simulations revealed that a subtle molecular “handshake” was interfering with electron motion. The discovery shows that liquids can briefly organize in ways that dramatically change how electrons behave.

Tiny bits of Earth’s atmosphere have been drifting to the moon for billions of years, guided by Earth’s magnetic field. Rather than blocking particles, the magnetic field can funnel them along invisible lines that sometimes stretch all the way to the moon. This explains mysterious gases found in Apollo samples and suggests lunar soil may hold a long-term archive of Earth’s history. It could also become a valuable resource for future lunar explorers.

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary particles. Researchers expected this transition to change how disordered the system is, but LHC data tell a different story. A newly improved collision model matches experiments better than older ones and reveals that the “entropy” remains unchanged throughout the process. This unexpected result turns out to be a direct fingerprint of quantum mechanics at work.

UK experts are warning that access to new weight-loss drugs could depend more on wealth than medical need. Strict NHS criteria mean only a limited number of patients will receive Mounjaro, while many others must pay privately. Researchers say this risks worsening existing health inequalities, especially for groups whose conditions are often missed or under-diagnosed. They are calling for fairer, more inclusive access before gaps in care widen further.

Seeing plastic trash while hiking inspired a Rutgers chemist to rethink why synthetic plastics last forever while natural polymers don’t. By mimicking tiny structural features used in DNA and proteins, researchers designed plastics that remain durable but can be triggered to fall apart naturally. The breakdown speed can be precisely tuned, from days to years, or switched on with light or simple chemical signals. The discovery could reshape everything from food packaging to medicine delivery.

A groundbreaking study shows that breast cancer screening works better when it’s personalized. Instead of annual mammograms for all, women were screened based on genetics, health history, and lifestyle factors. This approach reduced advanced cancers without increasing risk for those screened less often. Most women preferred the personalized model, hinting at a major shift in future screening guidelines.

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.

Overfished coral reefs are producing far less food than they could. Researchers found that letting reef fish populations recover could boost sustainable fish yields by nearly 50%, creating millions of extra meals each year. Countries with high hunger and nutrient deficiencies would benefit the most. Rebuilding reefs could turn ocean conservation into a powerful tool against global hunger.

Scientists have discovered a rogue planet roaming the Milky Way after combining observations from Earth and a space telescope. This rare dual perspective allowed them to weigh the planet and pinpoint where it lies in the galaxy. With a mass similar to Saturn, the planet likely formed around a star before being thrown out. The finding opens a new window into how planets are lost to interstellar space.

Researchers using China’s “artificial sun” fusion reactor have broken through a long-standing density barrier in fusion plasma. The experiment confirmed that plasma can remain stable even at extreme densities if its interaction with the reactor walls is carefully controlled. This finding removes a major obstacle that has slowed progress toward fusion ignition. The advance could help future fusion reactors produce more power.

New research shows Karnak Temple was built on a rare island of high ground formed as Nile river channels shifted thousands of years ago. Before that, the area was too flooded for settlement, making the temple’s eventual rise even more remarkable. The landscape closely mirrors ancient Egyptian creation myths, where sacred land emerges from water. This suggests Karnak’s location was chosen not just for practicality, but for its deep symbolic power.

Researchers compared a traditional Chinese medicine, Yueju Pill, with a standard antidepressant and found both reduced depression symptoms. However, only Yueju Pill increased a brain-supporting protein associated with mood improvement. Brain imaging showed that unique network patterns—especially in visual regions—could predict who benefited most from Yueju Pill. This opens the door to more personalized depression treatments guided by brain scans.

New research shows that AI doesn’t need endless training data to start acting more like a human brain. When researchers redesigned AI systems to better resemble biological brains, some models produced brain-like activity without any training at all. This challenges today’s data-hungry approach to AI development. The work suggests smarter design could dramatically speed up learning while slashing costs and energy use.

Feeling warm or cold doesn’t just register on the skin—it changes how connected we feel to our own bodies. Research shows that temperature sensations help shape body ownership, emotional regulation, and mental well-being. Disruptions in thermal perception are linked to conditions like depression, trauma, and stroke-related body disconnect. These insights could lead to new sensory-based mental health treatments and more lifelike prosthetics.
