Researchers at USF Health have discovered a new way opioid receptors can work that may lead to safer pain medications. Their findings show that certain experimental compounds can amplify pain relief without intensifying dangerous side effects like suppressed breathing. This research offers a fresh blueprint for designing opioids that last longer, work better, and pose fewer risks. It also opens doors to safer treatments for other brain disorders.

Mars looks familiar from afar, but surviving there means creating a protective oasis in a hostile world. Instead of shipping construction materials from Earth, researchers are exploring how to use Martian soil as the raw ingredient. Two tough microbes could work together to bind dust into a concrete-like material and even help generate oxygen. The vision: 3D-print habitats using local resources, one experiment at a time.

Many people with multiple sclerosis struggle with balance and coordination, and this study uncovers a hidden reason why. Researchers found that inflammation in the brain disrupts the energy supply of vital movement-controlling neurons. As their mitochondria fail, these cells weaken and eventually die, worsening motor problems over time. Protecting brain energy systems could open the door to slowing these symptoms.

Scientists have found that combining silybin with carvedilol works far better against liver fibrosis than either drug alone. The duo targets the root drivers of liver scarring, sharply reducing collagen buildup and liver damage in experimental models. Importantly, both drugs are already approved and commonly prescribed. That makes this discovery especially promising for rapid clinical translation.

Scientists have uncovered a surprising viral shortcut that turns moving cells into delivery vehicles for infection. Instead of spreading one virus at a time, infected cells bundle viral material into large structures called Migrions and pass them directly to new cells. This collective delivery jump-starts viral replication and boosts disease severity. The finding reveals a migration-based route of viral spread that defies classic models of infection.

A long-running debate over Tamiflu’s safety in children may finally be settled. Researchers found that influenza, not the antiviral medication, was linked to serious neuropsychiatric events like seizures and hallucinations. Even more striking, kids treated with Tamiflu had about half the risk of these events compared to untreated children with the flu. The results suggest the drug may be protective rather than harmful.

Nearly all women in STEM graduate programs report feeling like impostors, despite strong evidence of success. This mindset leads many to dismiss their achievements as luck and fear being “found out.” Research links impostorism to worse mental health, higher burnout, and increased thoughts of dropping out. Supportive environments and shifting beliefs about intelligence may help break the cycle.

The idea that we make over 200 unconscious food choices a day has been repeated for years, but new research shows the number is more illusion than insight. The famous figure comes from a counting method that unintentionally exaggerates how many decisions people really make. Researchers warn that framing eating as mostly “mindless” can undermine confidence and self-control. A more realistic view focuses on meaningful choices—and practical strategies that make healthy decisions easier.

New research shows gut bacteria can directly influence how the brain develops and functions. When scientists transferred microbes from different primates into mice, the animals’ brains began to resemble those of the original host species. Microbes from large-brained primates boosted brain energy and learning pathways, while others triggered very different patterns. The results suggest gut microbes may have played a hidden role in shaping the human brain—and could influence mental health.

A protein once thought to simply help cancer cells avoid death turns out to do much more. MCL1 actively drives cancer metabolism by controlling the powerful mTOR growth pathway, tying survival and energy use together. This insight explains why MCL1-targeting drugs can be effective—but also why they sometimes damage the heart. Researchers have now identified a way to reduce that risk, potentially unlocking safer cancer therapies.

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.

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.

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.

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.

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.

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.

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.

Researchers have discovered a way to help aging intestines heal themselves using CAR T-cell therapy. By targeting senescent cells that build up over time, the treatment boosted gut regeneration, reduced inflammation, and improved nutrient absorption in mice. It even helped protect the intestine from radiation damage, with benefits lasting up to a year. Early results in human intestinal cells suggest the approach could one day improve gut health in older adults and cancer patients.

Scientists may have cracked the case of whether a seven-million-year-old fossil could walk upright. A new study found strong anatomical evidence that Sahelanthropus tchadensis was bipedal, including a ligament attachment seen only in human ancestors. Despite its ape-like appearance and small brain, its leg and hip structure suggest it moved confidently on two legs. The finding places bipedalism near the very root of the human family tree.

The brain constantly blends split-second reactions with slower, more thoughtful processing, and new research shows how it pulls this off. Scientists discovered that brain regions operate on different internal clocks and rely on white matter connections to share information across these timescales. The way this timing is organized affects how efficiently the brain switches between activity patterns tied to behavior. Differences in this system may help explain why people vary in cognitive ability.

Researchers have uncovered thousands of preserved metabolic molecules inside fossilized bones millions of years old, offering a surprising new window into prehistoric life. The findings reveal animals’ diets, diseases, and even their surrounding climate, including evidence of warmer, wetter environments. One fossil even showed signs of a parasite still known today. This approach could transform how scientists reconstruct ancient ecosystems.

Time-restricted eating has been widely promoted as a simple way to boost metabolic health, but new research paints a more complicated picture. When calorie intake stayed the same, an eight-hour eating window did not improve insulin sensitivity or cardiovascular markers. What did change was the body’s internal clock, which shifted based on meal timing and altered sleep patterns. The results suggest calorie reduction, not the eating window itself, may be the real driver of health benefits.

Common diabetes drugs may do more than regulate blood sugar—they could also influence how cancers grow, spread, or slow down. Researchers are now unraveling how these medications affect immune function, inflammation, and tumor biology, with intriguing but still uncertain implications.

A powerful 7.4-magnitude earthquake struck northern Chile in July 2024—and it wasn’t supposed to be that strong. Unlike Chile’s infamous shallow “megathrust” quakes, this one ruptured deep inside the Earth, where shaking is usually weaker at the surface. Researchers discovered that the quake broke long-held assumptions by tearing through hotter rock layers than expected, fueled by a rare chain reaction that accelerated the rupture.

Being active boosts your daily calorie burn more than previously thought. Researchers found that increased physical activity raises total energy use without triggering the body to conserve energy elsewhere. Basic functions keep running at full speed, even as movement increases. The result: exercise truly adds to your energy output rather than being metabolically “offset.”

Scientists studying Alzheimer’s in African Americans have uncovered a striking genetic clue that may cut across racial lines. In brain tissue from more than 200 donors, the gene ADAMTS2 was significantly more active in people with Alzheimer’s than in those without it. Even more surprising, this same gene topped the list in an independent study of White individuals. The discovery hints at a common biological pathway behind Alzheimer’s and opens the door to new treatment strategies.

A newly discovered exoplanet is rewriting the rules of what planets can be. Orbiting a city-sized neutron star, this Jupiter-mass world has a bizarre carbon-rich atmosphere filled with soot clouds and possibly diamonds at its core. Its extreme gravity stretches it into a lemon shape, and it completes a full orbit in under eight hours. Scientists are stunned — no known theory explains how such a planet could exist.

A major update to how obesity is defined could push U.S. obesity rates to nearly 70%, according to a large new study. The change comes from adding waist and body fat measurements to BMI, capturing people who were previously considered healthy. Many of these newly included individuals face higher risks of diabetes and heart disease. The findings suggest that where fat is stored may be just as important as overall weight.

The Champagne Cluster is a rare and beautiful example of two galaxy clusters smashing together. Its festive name comes from both its New Year’s Eve discovery and its bubbly appearance in space. Images reveal superheated gas and galaxies spread across a massive collision zone. Astronomers believe this system could help explain how dark matter responds when giant structures collide.

New high-resolution images show that novae are anything but simple stellar fireworks. One exploded with multiple gas streams colliding almost immediately, while another shockingly delayed its eruption for more than 50 days before unleashing a powerful blast. These complex outflows create shock waves that produce intense gamma rays, confirming long-standing theories with direct visual evidence. The findings reveal novae as evolving, multi-stage events rather than single, instant explosions.

As we age, our immune system quietly loses its edge, and scientists have uncovered a surprising reason why. A protein called platelet factor 4 naturally declines over time, allowing blood stem cells to multiply too freely and drift toward unhealthy, mutation-prone behavior linked to cancer, inflammation, and heart disease. Researchers found that restoring this protein in older mice — and even in human stem cells in the lab — made aging blood and immune cells behave strikingly younger again.

Mars once had sprawling river systems that rivaled major watersheds on Earth, and scientists have now identified the biggest ones for the first time. Researchers mapped 16 massive drainage basins where water likely flowed long enough to support life. Even though these areas cover just 5% of ancient Martian terrain, they account for a huge share of erosion and sediment movement. That makes them some of the most promising places to search for ancient life.

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher fitness, while others slow or even derail progress. Two populations facing different kinds of change can end up on completely different evolutionary paths. The findings challenge the idea that one population’s response can represent a whole species.

A spectacular fossil trove on the Arctic island of Spitsbergen shows that marine life made a stunning comeback after Earth’s greatest extinction. Tens of thousands of fossils reveal fully aquatic reptiles and complex food chains thriving just three million years later. Some predators grew over five meters long, challenging the idea of a slow, step-by-step recovery. The find rewrites the early history of ocean ecosystems.

Neutrinos may be nearly invisible, but they play a starring role in the Universe. Long-standing anomalies had hinted at a mysterious fourth “sterile” neutrino, potentially rewriting the laws of physics. Using exquisitely precise measurements of tritium decay, the KATRIN experiment found no evidence for such a particle, sharply contradicting earlier claims. With more data and upgrades ahead, the hunt is far from over.

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the difference, showing that Mars clocks tick slightly faster—and fluctuate over the Martian year. These microsecond shifts could play a big role in future Mars navigation, communications, and even a solar-system-wide internet. It’s a small time gap with big consequences for space exploration.

As the immune system weakens with age, scientists have found a way to restore some of its lost strength. By delivering mRNA to the liver, they created a temporary source of immune-boosting signals that normally come from the thymus. Older mice treated this way produced more effective T cells and responded far better to vaccines and cancer treatments. The strategy could one day help extend healthy years of life.

Mars isn’t just dusty—it crackles with electricity. Scientists discovered that dust devils can generate tiny electric sparks, captured for the first time by Perseverance’s microphone. These static discharges may rapidly destroy chemicals like methane and reshape how Mars’ atmosphere works. The sparks could even affect climate patterns and pose risks to future missions.

Scientists have uncovered ancient wolf remains on a small Baltic island where wolves could only have been brought by humans. These animals weren’t dogs, but true wolves that ate the same marine food as the people living there and showed signs of isolation and possible care. One even survived with an injured limb that would have made hunting difficult. The findings suggest humans once kept and managed wolves in ways far more complex than previously imagined.

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed using the James Webb Space Telescope, which was able to isolate the blast from its faint host galaxy. Surprisingly, the explosion closely resembles supernovae linked to gamma-ray bursts in the modern universe.

Scientists have uncovered why big predators like sharks spend so much time in the ocean’s twilight zone. The answer lies with mid-sized fish such as the bigscale pomfret, which live deep during the day and rise at night to feed, linking deep and surface food webs. Using satellite tags, researchers tracked these hard-to-study fish for the first time. Their movements shift with water clarity, potentially altering entire ocean food chains.

Tiny lab-grown brains are offering an unprecedented look at how schizophrenia and bipolar disorder disrupt neural activity. Researchers found distinct electrical firing patterns that could identify these conditions with high accuracy. The discovery opens the door to more precise diagnoses and personalized drug testing. Instead of guessing medications, doctors may one day see what works before treating the patient.

Researchers say fusion reactors might do more than generate clean energy—they could also create particles linked to dark matter. A new theoretical study shows how neutrons inside future fusion reactors could spark rare reactions that produce axions, particles long suspected to exist but never observed. The work revisits an idea teased years ago on The Big Bang Theory, where fictional physicists couldn’t solve the puzzle. This time, real scientists think they’ve found a way.

Weight loss restored healthy metabolism in both young and mid-aged mice, but the brain told a different story. In mid-aged animals, slimming down actually worsened inflammation in a brain region tied to appetite and energy balance. While this inflammation eventually subsided, brain inflammation has been linked to cognitive decline and neurodegenerative disease. The results suggest that weight loss in midlife may not be as straightforward as once thought.

A randomized trial from Vanderbilt-Ingram Cancer Center reveals that magnesium may be the missing key to keeping vitamin D levels in balance. The study found that magnesium raised vitamin D in people who were deficient while dialing it down in those with overly high levels—suggesting a powerful regulating effect. This could help explain why vitamin D supplements don’t work the same way for everyone and why past studies linking vitamin D to cancer and heart disease have produced mixed results.

A major new review has put hundreds of alternative autism treatments under the microscope—and most didn’t hold up. Scientists analyzed decades of research and found little reliable evidence that popular approaches like probiotics, acupuncture, or music therapy truly work. Alarmingly, safety was often ignored, with many treatments never properly evaluated for side effects. The researchers stress that looking at the full body of evidence matters far more than trusting a single hopeful study.

When researchers lowered whale bones into the deep ocean, they expected zombie worms to quickly move in. Instead, after 10 years, none appeared — an unsettling result tied to low-oxygen waters in the region. These worms play a key role in breaking down whale remains and supporting deep-sea life. Their absence hints that climate-driven oxygen loss could unravel entire whale-fall ecosystems.

In collisions at CERN’s Large Hadron Collider, hotter than the Sun’s core by a staggering margin, scientists have finally solved a long-standing mystery: how delicate particles like deuterons and their antimatter twins can exist at all. Instead of forming in the initial chaos, these fragile nuclei are born later, when the fireball cools, from the decay of ultra-short-lived, high-energy particles.

Stanford scientists have uncovered how mRNA COVID-19 vaccines can very rarely trigger heart inflammation in young men — and how that risk might be reduced. They found that the vaccines can spark a two-step immune reaction that floods the body with inflammatory signals, drawing aggressive immune cells into the heart and causing temporary injury.

UBC Okanagan researchers have uncovered how plants create mitraphylline, a rare natural compound linked to anti-cancer effects. By identifying two key enzymes that shape and twist molecules into their final form, the team solved a puzzle that had stumped scientists for years. 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.

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone emergency fix that helps them survive. Some cancer cells rely heavily on this backup system, even though it makes their DNA more unstable. Blocking this process could expose a powerful new way to target tumors.

A newly identified region on Mars may hold the key to future human landings. Researchers found evidence of water ice less than a meter beneath the surface, close enough to be harvested for water, oxygen, and fuel. The location strikes a rare balance between sunlight and cold, helping preserve the ice. It could also offer clues about whether Mars once supported life.

New observations reveal that the relationship between ultraviolet and X-ray light in quasars has changed over billions of years. This unexpected shift suggests the structure around supermassive black holes may evolve with time, challenging a decades-old assumption.
