Every piece of research we've covered — across genetics, neuroscience, ecology, immunology, and more.
Researchers built a head-mounted microLED array that stimulates a monkey's visual cortex at up to a million points across a centimeter of brain. It reliably evoked visual sensations for more than a year.
A study of the brain coral Pseudodiploria strigosa tracked gene activity across a full day and found the coral, its algae, and its microbes each shift function on their own daily schedule. The result is a holobiont that keeps time as a coordinated whole.
Researchers engineered a friendly gut bacterium and paired it with a milk sugar to starve and disarm a dangerous strain of E. coli in mice and rabbits, avoiding the toxin surge that antibiotics can trigger.
A common gut bacterium is depleted in children with epilepsy. Restoring it calmed seizures in mice and in a clinical trial, working through a nerve circuit that runs from the colon to the brain.
Researchers found a small mobile peptide that travels from an infected leaf to distant, healthy leaves and tells them to slam their pores shut. It reveals how a plant can mount a body-wide defense from a single point of attack.
A Stanford-led team built MedHELM, a benchmark that tests medical AI on 121 real clinical tasks instead of licensing-exam trivia. The results reshuffle which models look best once cost is counted.
A global meta-analysis finds that climate change, pollution, fire, and intensive farming cut the feeding activity of soil detritivores by nearly half. Drought and insecticides were the harshest offenders.
A UMass Chan team engineered a suppressor tRNA that reads through a common type of premature stop mutation and packaged it into a gene-therapy virus. One dose restored about 10 percent of enzyme activity in mice with two lysosomal storage diseases.
Researchers traced a three-part circuit connecting the injured heart to the brainstem and back during a heart attack in mice. Cutting any node of the loop shrank the damage.
A dense yearlong study of nursery infants found that babies transmit gut bacteria to each other, with peer-acquired strains rivaling those inherited from family. Social contact in infancy turns out to be a major force shaping the microbiome.
Researchers built E. coli that senses gut bleeding, then sticks to the wound using a barnacle adhesive and pumps out a repair protein. In mice, a single dose calmed inflammatory bowel disease for over a week.
Researchers found that Epstein-Barr virus reshapes which protein fragments an infected B cell displays, causing it to show the same myelin peptides seen in the brains of multiple sclerosis patients. The work ties a common virus and a known genetic risk factor into one mechanism.
Root-knot nematodes track down maize by reading defensive chemicals the plant leaks into the soil. A new study shows those chemicals work by rearranging the root's bacterial neighbors, which then give the pest its directions.
Researchers built a deep-learning imaging pipeline called CaMVIA-3D that reconstructs heart muscle in three dimensions, cell by cell. It found that different genetic causes of hypertrophic cardiomyopathy leave different structural fingerprints in the tissue.
A global meta-analysis finds that plastic mulch lifts crop yields by nearly 29 percent and water efficiency by almost half, while leaving behind residues and nanoplastics that degrade soil. Researchers lay out six ways to keep the benefits without the damage.
Researchers profiled roughly 250,000 cells from human fetal cortices to see how a third copy of chromosome 21 disrupts early brain development. They pinpointed three dosage-sensitive regulators and showed that turning them down partly restored normal gene activity.
Tracking the same neurons in mice for weeks, researchers watched the hippocampus stop reacting to a reward and start anticipating it. Cells that once fired at the payoff gradually shifted to fire at the cues that came before.
In a study of 22 patients with auto-brewery syndrome, researchers traced their unexplained intoxication to gut bacteria that ferment carbohydrates into ethanol. The culprits were common gut microbes running the wrong metabolic pathways.
Researchers engineered tiny bubbles shed by bacteria to carry a checkpoint-blocking antibody and antigen-coding DNA into solid tumors, helping CAR-T cells attack cancers that would normally evade them. In mice, the approach curbed breast tumor recurrence and spread.
A large phase 3 trial in Vietnam tested whether a patient's LTA4H genotype should decide who gets steroids for tuberculous meningitis. The tidy hypothesis did not survive contact with the data.
Wounding a gladiolus corm makes its sleeping buds sprout sooner. Researchers traced the effect to a hormone signal that reroutes sugar to the bud and switches on a gene called GhZAT11.
A new platform called SPARK-seq screens thousands of DNA-based binders against cell-surface proteins in one run, and measures how tightly each one holds on. It could speed up the design of diagnostic reagents and targeted drugs.
Darwin's frog lives entirely on land, yet an aquatic fungus is collapsing its populations in southern Chile. A new study shows the killer spreads at the scale of a few metres, hiding epidemics that erase up to 98 percent of a group in a year.
A study of more than 900,000 UK Biobank and All of Us participants found that many human genomes carry short DNA repeats that keep expanding in blood as people age, and that inherited variants tune how fast they grow.
Researchers recorded brain activity across seven lizard species, humans, rats and pigeons and found the same slow rhythm during sleep. The finding suggests a deep evolutionary root for how the sleeping brain organizes itself.
A survey of eight Australian tree species finds their bark is a busy microbial habitat, home to bacteria that consume methane, hydrogen, and carbon monoxide. The finding adds a new, overlooked player to how forests trade gases with the atmosphere.
Researchers built proteins from scratch that stay apart until a common antiviral drug shows up, then lock into precise clusters. The drug becomes an on-switch for where proteins go and what genes turn on.
Some people are exposed to tuberculosis bacteria and never get sick. A new study finds a long non-coding RNA circulating in their blood that reprograms immune cells to fight the pathogen, and it made the century-old BCG vaccine work better in mice.
Researchers rewrote genes in the chloroplast of a green alga so that 13 of the standard 64 codons were never used, shrinking the working genetic code to 51. The recoded cells still grew and photosynthesized normally.
In a randomized primary-care trial, an AI reading routine heart tracings flagged patients hiding advanced liver scarring. Doubling new diagnoses turned out to be the easy part.
A continent-wide study maps sodium in African plants and finds it varies more than a thousandfold. Where salt is scarce, the largest herbivores like elephants tend to be scarce too.
In the VIBRANT-HD trial, an oral drug called branaplam became the first splicing modulator to lower mutant huntingtin protein in the spinal fluid of people with Huntington's disease. Nerve damage in most participants forced the study to stop early.

In pregnant mice, gut bacteria calm the mother's immune system at the placenta by producing tryptophan-derived molecules. Strip out the microbes and pregnancies fail. The same signatures were disrupted in human recurrent miscarriage.
Researchers traced how bright light dampens feeding in mice, following the signal from a specific class of retinal cells to an appetite hub deep in the brain. Turning the pathway on cut food intake and slowed weight gain.
A gut bacterium can detect a chemical that Candida albicans uses to talk to its own kind, and uses that eavesdropped signal to fire a molecular weapon at the fungus. The finding shows bacteria and fungi negotiate the gut through shared chemistry.
A hormone-controlled gene called CsARF3 steers cucumber flowers toward male or female. Deleting it made plants grow only male flowers; boosting it made more female ones.
A brain-computer interface that lets a paralyzed person move a cursor loses accuracy as neural signals drift, forcing regular recalibration. Researchers built a method that infers where the user is aiming and retunes the decoder on its own, holding up over a month in a human user.
A synthesis of 681 crop fields on three continents finds that pesticides and habitat loss cut into wild bee populations independently. Planting flowers nearby does not shield bees from the chemicals.
A genetic study of nearly 2.9 million people mapped hundreds of DNA regions tied to aortic stenosis, a common valve disease with no drug treatment. Two of the genes turned out to control valve hardening in the lab.
A study in mice traces the everyday act of hesitating to one specific route through the brain's action-control hub. The indirect pathway, not its better-known counterpart, is what puts the brakes on when the next move is uncertain.
Researchers engineered E. coli to display a colibactin-neutralizing protein on its surface, protecting gut cells from a cancer-linked bacterial toxin. In mice, the modified bacteria reduced colon tumors driven by pks+ E. coli.
Researchers used a new AI tool called RFdiffusion2 to design zinc-powered enzymes from nothing but active-site chemistry. The best worked straight off the computer, no lab tweaking required.
Researchers in Vienna traced Candida auris's grip on human skin and its resistance to a last-line antifungal to a single CO2-sensing enzyme. Even neighboring skin bacteria feed the fungus the gas it needs.
A 26-site international experiment found that grasslands sown with up to six forage species out-yielded a heavily fertilized grass monoculture while using less nitrogen. The advantage grew at the warmest sites.

A 2022 test of a commercial deep-sea mining machine on the Pacific abyssal plain cut animal density by 37 percent and species richness by 32 percent inside its tracks. Two years of before-and-after data let researchers separate the machine's damage from the ocean floor's own restlessness.
A team at the Broad Institute used prime editing to turn a spare human tRNA gene into a suppressor that reads through premature stop codons. In cells and in mice, one editing tool rescued several different genetic diseases.
Researchers assembled artificial cells from purified molecules and got a T7 bacteriophage to run its entire infection cycle inside them, from docking to the release of new virus particles. It is the first time viral infection has been rebuilt entirely from defined parts.
Some friendly gut microbes make antibiotic-like weapons to defend their patch of intestine. A new study shows that one such bacterium can hollow out the rest of the microbiome and leave the gut open to dangerous pathogens.
In a small proof-of-concept trial, seven of ten people with HIV controlled the virus for a stretch after pausing their daily pills, following a three-part immune-boosting regimen. Early bursts of killer T cells tracked with better control.
A man in Germany has stayed free of HIV for more than six years after a stem cell transplant, without the rare double mutation that was thought to be required. The case points to viral reservoir clearance, not genetic resistance, as the driver of cure.
Compacted soil stops roots from growing down, so they thicken instead. A new Nature study traces that swelling to ethylene switching off cellulose-making genes inside root cells.
A new study finds that some plants warm their reproductive cones and broadcast thermal infrared to draw in beetle pollinators. The beetles carry infrared-sensing neurons tuned to match, and the signal may predate flower color.
Yale researchers built pan-ExM-t, a method that physically swells brain tissue up to 24-fold so a standard confocal microscope can see individual synapses and organelles. It pairs that anatomical detail with antibody labeling of specific proteins.
A single-infusion AAV gene therapy carrying a hyperactive Factor IX gene cut the annual bleeding rate to 0.6 across 26 patients with hemophilia B in China. Most participants went a full year with zero bleeds.
A single dose of psilocybin reorganizes which brain regions feed into the mouse frontal cortex. New tracing work shows the rewiring depends on the drug-driven electrical activity itself, not just the drug.
A long-term study of forest north of Manaus found that intense hot droughts kill trees fast, especially fragile pioneers. Researchers argue these droughts preview a "hypertropical" climate that could cover much of the tropics by 2100.
A phase 3 trial delivered the SMA gene therapy onasemnogene abeparvovec directly into spinal fluid, reaching older children who had aged out of the standard IV version. Motor scores improved over a sham procedure.
Scientists mapped the whole pigeon brain to see which cells light up in a magnetic field. The trail led to the inner ear and a balance circuit, not the beak.
Columbia researchers built a tool called MetaEdit that inserts new genes into gut bacteria while they sit inside a living animal, no petri dish required. It even edited a species nobody has managed to grow in the lab.
Researchers built a one-pot CRISPR test that flags monkeypox virus in about 11 minutes and reads out multiple DNA targets at once. On clinical samples it matched lab PCR while reporting five times faster.
Chinese researchers turned a plant virus into an engine for directed evolution inside living leaves. Their GRAPE system screens huge libraries of gene variants in four days and rebuilt two crop immune receptors.
A first-in-human trial used CRISPR to permanently switch off a cholesterol-linked gene inside the liver. At the higher doses, one infusion cut blood levels of the ANGPTL3 protein by about 80 percent.
Recordings from living human brain tissue show that neurons around aggressive gliomas are more electrically excitable, and that this extra firing pushes the tumor to divide faster. The finding points to the electrical conversation between brain and cancer as a driver of malignancy.
Researchers built a gene-by-gene, location-by-location atlas of 61 human livers spanning healthy tissue to advanced fatty liver disease. It flags a group of immune cells that seem to shield the organ rather than harm it.
Lecanemab is often described as an antibody that binds and removes amyloid. A new study says the antibody barely clears anything on its own. The real work is done by microglia, the brain's resident immune cells, and only when the antibody can call them in.
Stanford researchers dosed lab-grown gut bacterial communities with 707 drugs and found that a single rule, competition for nutrients, largely predicts which species surge and which vanish. The work offers a way to anticipate a drug's collateral damage to the microbiome.
A transformer model called GEMORNA generates mRNA sequences from scratch, boosting protein output up to 41-fold over an optimized benchmark in cells. The approach also extended to circular RNA and CAR-T cells.
A phase 3 trial in Uganda, Kenya and South Africa found that switching stable HIV patients from daily pills to injections every eight weeks kept the virus suppressed in 97 percent of people at 96 weeks. The result matched daily oral therapy.
A crop model run across Africa projects that overlooked staples like cassava, teff and finger millet could gain ground under climate change, while maize and several familiar cash crops lose it.

Researchers built mice whose APOE gene can be flipped from the high-risk E4 version to the protective E2 version on command. Switching it, even briefly and only in astrocytes, cut amyloid pathology and improved memory.
Engineers built an optical fiber thinner than a pencil lead that can beam light from more than a thousand points along its length. In mice, aiming that light at different depths of one brain region triggered different escape behaviors.
A fungus that ruins wheat harvests wins by making the plant less acidic. Researchers found that certain Pseudomonas bacteria living on the wheat head fight back by pumping out organic acids, and field trials showed they can hold the disease in check.
Fast-growing cells dilute the proteins that run engineered genetic circuits, wiping out their behavior. A team fused those proteins to sticky sequences that clump at their target genes, keeping circuits stable and boosting a chemical production pathway.
A common gut symbiont makes a fat molecule that calms a class of immune cells. Researchers found that many other gut bacteria make a look-alike molecule that does the opposite, blocking the signal.
Legume roots use nearly identical receptors to attack fungi and to welcome nitrogen-fixing bacteria. Danish researchers found that swapping just two amino acids flips one setting to the other, hinting at how symbiosis might be engineered into other crops.
A new sequencing method reads messenger RNA from the human cells shed into stool, turning a routine sample into a noninvasive window on the gut. In mice it tracked inflammation and recovery over time, and it sorted IBD patients by disease severity.
A new accounting of biomass on the move finds that human travel dwarfs the combined movement of all wild birds, land mammals and arthropods. Marine animal movement, still the planet's largest, has halved since 1850.
Researchers used a graph neural network to sift enzymes for one that survives industrial recycling conditions. The winner, PURase, depolymerized commercial polyurethane at kilogram scale in eight hours.
A subset of unusually large brain waves during sleep carries the day's memories from the hippocampus to the cortex. Boosting them in mice made the animals remember better.
Researchers selected mice for lower activity by transferring gut microbiomes, not by breeding the animals. After four rounds, the recipients moved less, and a single bacterial metabolite could reproduce the effect.
A protein language model called MAGE designed working human antibodies against three viruses without starting from any known binder. The catch is that the hit rate is still low, and every design was checked in the lab.
Marburg virus kills up to nine in ten people it infects, and no vaccine or drug is licensed against it. Researchers now report a single human antibody that neutralizes every known Marburg strain and protected guinea pigs from a lethal challenge.
Researchers in China found that switching off a single maize gene, ZmDapF1, makes seedlings survive drought better and keeps grain yield high in normal fields. The gene works by throttling a chloroplast enzyme tied to photosynthesis.
A deep-learning model called HER2 MAP reads pretreatment breast scans to predict a tumor's HER2 status without a needle. Trained on 14,472 images from 6,991 patients, it beat biopsy at forecasting who responds to therapy.
A new Nature study tracks the work animals do across sub-Saharan Africa as energy flowing through food webs. Since a pre-industrial baseline, that flow has fallen by more than a third, with megafauna functions collapsing outside protected areas.
Researchers identified a family of cholesterol-handling receptors that yellow fever virus grabs to enter cells. Soluble decoy versions of those receptors protected mice from infection.
Researchers assembled chromosome-scale genomes for 33 wild and cultivated oat lines and mapped gene activity across six tissues, giving breeders a detailed map of a crop whose genome has long lagged behind other cereals.
A grain weevil houses bacteria that survive on a diet of pure cereal. New imaging shows those bacteria build elaborate internal tubes to hand carbohydrates back to their host.
Researchers scanned stored blood from people who later developed multiple sclerosis and found signs of myelin damage about seven years before their first symptom. The work points toward a protein blood test for catching the disease early.
A new analysis projects that global plant productivity will peak around mid-century and then fall, as warming-driven atmospheric dryness cancels out the fertilizing boost from rising carbon dioxide.
Researchers link germline variants in the presynaptic gene UNC13A to a newly defined neurodevelopmental syndrome, and show the same gene can misfire in three distinct ways. The finding sorts affected children into three functional subtypes.
A study in Nature finds that star-shaped glial cells called astrocytes form their own memory ensemble, primed by a frightening experience and locked in by repetition. When the researchers disrupted it, memories grew shakier and less precise.
A new study shows that fungal threads linking plant roots can carry a chemical alarm from a sick plant to its healthy neighbors. The warned plants then reshuffle their root microbiome to fend off the same pathogen.
MIT engineers built editable promoters that let them dial a gene's activity to precise, stable levels and pass those settings on to daughter cells. The tool, called DIAL, could make gene circuits far more predictable.
When herpes or flu viruses infect a cell, a sensor called ZBP1 can trigger a self-destruct program. A new study finds the molecule that sets it off comes from the host's own genome, not the virus.
In the ginger Alpinia mutica, some flowers release pollen in the morning while others are ready to receive it, then they swap in the afternoon. Researchers traced this timed dance to a single gene, SMPED1.
