Every piece of research we've covered — across genetics, neuroscience, ecology, immunology, and more.
A transistor sensor measured three forms of alpha-synuclein in brain-derived vesicles from blood and sorted 57 blinded samples with 87.7% accuracy. The cohort is small, and the thresholds came from the same team's pilot work.
Many inherited arrhythmia mutations break a heart sodium channel in two ways at once. A nanobody carrying two separate tools fixed both in cells, though nobody has yet shown it stops an arrhythmia.
Chlamydia's infectious form crushes its DNA into a dense ball. Super-resolution imaging put a hijacked host lipid inside that ball, and showed it leaving before the DNA unpacks.
E. coli wearing a polymer light-harvesting coat, with cadmium sulfide crystals grown inside it, made up to 30 times more malate under light. The absolute figure is 47 milligrams per litre, and glucose is still doing most of the work.
A Dutch coastal meadow arranges itself into vegetated mounds and bare salty pits. The pits are not wasted ground: rain carries salt into them, and that is part of what keeps the mounds alive.
Only about a third of dopamine release sites actually release. The ones that do sit pressed against neurons carrying dopamine receptors, which is hard to square with the idea that dopamine just diffuses.
A tea-plant enzyme makes two antifungal compounds instead of one by running its reaction in both directions. Cultivars carrying a single-base change that disables it get gray blight.
Clams lifted half a metre off a cold-seep floor lost their access to sulfide within days. Their resident bacteria shifted to a second sulfur compound, and the host either stopped digesting them or started.
A CRISPR-Cas13a assay names nine bacterial species and four resistance genes from a positive blood culture using a heat block and a basic fluorometer. Scored per patient sample rather than per well, it got 81% exactly right.
In kidney biopsies from 194 patients with protein-leaking disease, the filtering units that used their two gene copies most unequally belonged to the patients who did best.
Hemagglutinin variants from a hospitalised H5N1 patient bound bird-type receptors far less well than usual, and human-type ones barely at all. The live virus was never isolated.
A phenol-modified alginate stays liquid until tumour cells' own lactate fuels the chemistry that crosslinks it, building a stiffness gradient about a millimetre deep that then changes how those cells behave.
Japan's 2025 bear crisis is usually blamed on more bears. An 18-year analysis in Tohoku points instead to a beech crop whose lean years have grown leaner since 2006, and a year when the bears' backup food failed too.
Looking sideways while moving forward adds a rotational swirl to the image on the retina. Cancelling it removed people's heading errors, and over-cancelling it reversed them.
An engineered circuit listens for a step every one of these RNA viruses must take, then switches on resistance. It protected against three viruses with no growth cost the authors could measure.
Clostridium immunis secretes a phosphocholine-tagged sugar that prevented and reversed obesity in mice by lowering IL-22. Deleting the genes for the tag abolished the effect; the human evidence is still only an association.
Across three annual rounds in 142,250 people, the multi-cancer blood test rarely gave false alarms and usually named the right organ, but its sensitivity ran from 26.7% to 37.2%, and late-stage cancers did not fall.
BMPR2 is known for the lung disease its broken versions cause. Six people carry one recurring variant that does the opposite, and in flies it signals without waiting for its trigger.
Of a phage's five structural proteins, only antibodies against the fiber and the nozzle caused treatment failure in mice. They block infection and speed immune clearance, so escaping neutralisation only partly helps.
Protea-Tac hands target proteins directly to the proteasome without ubiquitin tagging, and slowed tumour growth in mice. It is a delivered protein rather than a pill, and recruitment alone did not always destroy the target.
Three genetic lineages of the common reed differ in heat tolerance, and the toughest one is gaining both genes and projected habitat. The species stays put on the map while changing underneath.
A double-blind sham-controlled trial in 46 adults tracked procrastination in daily life. Improvement followed a rise in how much the outcome was valued, not any drop in how unpleasant the task felt.
Most late-blight resistance genes are defeated within years. R8 has lasted nearly a century, and its own relatives turn out to hold it back, which the authors argue is why the pathogen never evolved around it.
Healthy mice cannot be infected with Campylobacter at all. Inflaming the gut strips out the bacteria that make indole, and without it the pathogen can run the energy pathways it needs to colonise.
Two hours of isoflurane shifted 38 of 265 serum metabolites at least twofold and rewired brain and pancreas metabolism. A tail vein catheter that runs in awake mice avoids most of it, and labels half as much.
Irradiated bdelloid rotifers pass broken chromosomes to their offspring unrepaired, then reconstruct them gradually across generations by copying the intact homolog.
Schistosomes only become male and female inside a host, which has kept that step out of reach for 40 years. Changing one ingredient in the culture medium reproduces it, though the worms still lay no eggs.
Two coral cores spanning 270 years show Mississippi-derived nitrogen climbing from near zero to roughly two-thirds of the supply reaching the healthiest reefs in the continental United States.
Cable bacteria carry current across centimetres of seafloor. The conductor inside them turns out to be a stacked nickel-organic framework, a material class chemists build and biology was not thought to make.
Mutating DEAF1 leaves human cortical organoids building progenitors instead of neurons. Reanalysis of 36 other high-risk autism genes finds 27 doing the same thing through the same pathways.
Across 160 adults, measures built to isolate the cerebellum held steady into the ninth decade while general sensorimotor performance declined, even as cerebellar grey matter visibly shrank.
Repeats expand far more often than they contract across 1,043 wild Arabidopsis genomes, and the variation maps to rare alleles in DNA repair, replication and methylation genes that are commonest where selection is weakest.
H. pylori sits on the stomach surface and never invades the tissue below. The tissue below is nonetheless where the damage gets decided, through a relay that leaves the lining and comes back.
Evidence that marine heatwaves damage fisheries has been mixed. Studying heat and low ocean productivity together, across three decades of global catch data, shows why: the combination behaves differently from either on its own.
Markers that predict poor outcomes when present at diagnosis predict the opposite when they appear after treatment. In leukemia samples, chemotherapy-induced senescence turns cancer cells into something T cells can see.
Susceptibility testing decides which antibiotic a UTI patient gets, yet a third of women are reinfected within a year. Rebuilding the test to resemble an actual bladder shows the front-line drug losing ground at every step.
An eight-letter genetic alphabet already works in DNA copying. Putting it through the transcription machinery that cellular life actually uses shows it passes the enzyme's checks, and reveals why the obvious fix for its main error backfires.
A beetle's gut bacterium has shed so much of its genome that it cannot survive the days it spends outside the host. The protein that carries it through turns out to come from a family known for making colour.
It is the standard illustration of convergent evolution: a marsupial shaped like a wolf. Putting absolute size back into the measurements, which these methods normally discard, undoes the comparison.
DNA methylation already sorts brain tumours into groups that behave differently. Asking what those patterns actually do turns a classifier into a chain of cause and effect, with one step still missing.
A stable map of space and a distinguishable memory of each trip through it look like competing demands. Recordings from rats show the two signals riding on separate axes in the same neurons.
Membrane organisation is usually explained by proteins and lipids, with the outer sugar layer treated as decoration. Watching 39 synthetic sugar-lipids one molecule at a time suggests the sugars are doing structural work of their own.
A protein central to cellular recycling has been solved structurally many times, almost always floating in solution. Anchor it to a membrane and a control site appears on the far side that was not there before.
Most people inhale the same allergens and never develop asthma, which implies something normally holds the response back. Deleting one receptor in mice made the disease worse, and airway cells from people with asthma carry less of it.
Older bone heals slowly, and the usual assumption is that the cells have deteriorated. Mapping where repair actually starts points somewhere else: the precursor cells are still there, but the signals around them are not.
Theory says coexisting species need roughly as many limiting factors as there are species. Reading those axes off the competition itself, across 12 communities worldwide, gives three at most.
The genes behind flowering are well mapped. The shape of the change is not. Measuring the timing shows the growing tip hesitates on its way across, which is the signature of a particular kind of switch.
Estimates of how much these ocean protists get from the algae living inside them ranged from 80 percent of their daily carbon to under 1 percent. Measuring individual molecules rather than bulk carbon explains why.
Bird flu has killed at least 1.4 million wild birds since 2021. Decades of ringing data on one tern population show the deaths were not distributed evenly by age, which changes what the toll means.
Five studies describe what a long non-coding RNA does in diseased blood vessels. A new objection argues that nobody established it is a separate RNA rather than part of the gene it sits inside.
Almost every attempt to recover ancient DNA from northeastern Africa has failed. A study of 148 inner ears reconstructs the region's population history anyway — and is careful about what shape alone can prove.
Most swallowed vitamin A goes straight to the liver. A new mouse study shows the gut microbiota controls the sliver that reaches developing T cells, using two separate signals.
Every cell holds a membrane potential, not just neurons, but in ordinary cells the interesting fluctuations are fractions of a millivolt and have been unmeasurable. An indicator sensitive enough shows that being wired to your neighbours quiets you.
Generating a hundred plausible protein designs is routine. Working out which ones behave correctly is not, especially when the property you want is self-organization over time rather than a number you can read off a plate.
Rye's genome is more than twice the size of a human's and mostly repetitive, which is why its centromeres have never been assembled. Finishing them showed those regions are still being actively rebuilt, unlike wheat's.
Years of work have gone into making gene editors more precise. The step that actually limits most therapies is getting them inside the cell, and a screen of 19,114 genes found which of the cell's own proteins are in the way.
An unrooted tree says who is related to whom, not what came first. For the archaea, three incompatible root positions have been proposed, and each implies a different founding organism. One modelling assumption turns out to have been driving the disagreement.
Programmable antibiotics promise that resistance becomes a software problem: rewrite the sequence. That only works if bacteria adapt to the sequence. Across 90 evolved lines, they mostly adapted to the peptide carrying it in.
Two problems have dogged the neurobiology of language: nobody agrees what language is, and the relevant areas sit in different places in different people. A method that ignores both keeps finding the same network anyway.
Michigan has kept newborn blood spots since 1987 and runs a cancer registry, so the two can be linked. Sequencing the infant spots of children who later developed cancer shows how much was already legible on day one.
Retinal organoids self-organize correctly and then stall short of maturity. They are also grown in the dark, in defiance of the fact that a real retina develops under light. Supplying it, at one particular flicker rate, helped.
Nobody assigns a vaccine at random, so the people who get one differ from those who don't in ways that also determine who ends up in hospital. A Swedish study of 245,696 elderly residents measured how much that distorts the answer.
A membrane with channels a few angstroms wide can swing its conductance up or down depending on what binds to it, which is a real advance in sensing. The diagnostic accuracy attached to it needs reading more carefully.
The methylguanosine cap is supposed to mark messenger RNA for translation. It turns out to sit on nearly all transfer RNA precursors too, and under heat stress those precursors compete for the very factor that messages need.
Testing 1,224 pairings between gut bacteria produced the expected result that most interactions are inhibitory, and an unexpected one about what the inhibition actually is. Restore the nutrients and almost all of it vanishes.
For two decades one protein has been credited with building the heme crystals that malaria parasites depend on, largely because it does so in a test tube. Tagged at its own genetic locus, it turns out to live somewhere else entirely.
Darwin suspected in 1875 that some Saxifraga species ate insects, and his experiments were inconclusive. An alpine species has now cleared all four criteria for carnivory, and it turns out to trap almost exclusively the insects that never pollinate it.
Extinctions are usually explained by the size of the shock. A dynamical-systems reading of 539 million years suggests the state the climate was already in mattered as much, and that life suffered most at the switches between states.
Tremor and slowness respond to dopamine. The instability and gait failure that cause falls do not, which suggests they run through different circuitry. One candidate sits in the brainstem, wired into the same motor hubs.
HIV strips the gut lining early, and suppressing the virus does not rebuild it. A metabolite made by gut bacteria activates the exact repair pathway the virus shuts down, and the pathway long-term non-progressors keep running.
Existing drugs for pulmonary fibrosis are systemic, and many patients quit them over side effects. A phase 1b trial of an inhaled peptide found no detectable drug in the blood at any dose, and biomarker signals that need reading carefully.
Finning bans are the most widely adopted shark conservation measure in the world, and shark mortality has risen throughout their spread. An analysis of 188 countries finds they changed where trade flows, not how much.
Three women with decades of recurrent urinary infections received phage therapy. The bacteria survived. Two years later the infections had largely stopped, which raises an awkward question about what phage trials have been measuring.
Fat cannot cross the intestinal wall until bile packages it. Gut bacteria turn out to control that packaging step, cutting absorption by more than half in mice, which is a larger effect than the drugs prescribed to do the same thing.
Whether cortical stimulation can evoke touch was settled years ago. Whether the same electrodes still do it a decade later is the question that decides if sensory implants are a product or an experiment.
Gene editing has always been better at switching genes off than putting new ones in, because inserting one means cutting DNA clean through and hoping the cell repairs it properly. A Tsinghua team found a way to skip the cut.
The fear that has shadowed stem-cell therapy is that cells able to become anything might become a tumour. Four people with complete spinal cord injuries have now carried iPSC-derived grafts for years without one.
Catfish in a lake straddling Vermont and Quebec have been turning up with melanomas since 2012. Sequencing the tumours showed they are not each fish's own cancer, but one lineage that has been moving between them.
Gene therapy is usually a one-time shot, because the immune system learns the delivery virus and blocks any repeat. Four children deaf from birth, already carrying those antibodies, received a second dose in their untreated ear, and hearing improved in all four.
Insects rule the land and almost never the open sea, and the standard explanation blamed their air-filled breathing tubes, which should implode under pressure. In Lake Malawi, larvae have rebuilt those tubes into crush-resistant sacs and drop hundreds of metres every day to escape fish.
Propping open a narrowed vein can relieve dangerously high pressure inside the skull, and nobody could fully explain why. Scans of patients and a mouse experiment point to the lymphatic vessels in the brain's own wrapping.
Heavier patients have long seemed to do better on checkpoint inhibitors, and nobody could say why. Across twelve mouse diets, the answer looks less like body fat and more like the gut bacteria that certain diets feed.
A few people with HIV make antibodies that disable strain after strain. Nobody had managed to produce them with a shot. In outbred monkeys, a vaccine designed to wake the right rare cells finally did, and the antibodies gripped the virus exactly as the designers predicted.
Long before a root reaches decaying plant matter, it swerves. It is reading the acid that fungi leave behind, converting an outside pH gradient into a hormone imbalance and finally into a physical bend away from the rot.
Researchers pulled the light-harvesting membranes out of plants, shrank them into a nanoscale package, and slipped them into mammalian corneal cells. Shine light on them and they do what a leaf does, making NADPH and ATP and easing the oxidative stress around them.
As the body ages, the immune scavengers that clear dead cells go quiet, and the corpses of spent white blood cells pile up and inflame the organs around them. In old mice, blocking one receptor switched the cleanup back on and held off decline in brain, muscle, heart and more.
A circular RNA hands instructions to an editing enzyme cells already carry, skipping past a broken stretch of the dystrophin gene. In monkeys the effect held at least a year and a half; in the first three patients, one dose was safe and came with measurable gains in movement and breathing.
A greasy ester found on naked mole-rat queens, and almost nowhere else in the colony, registers in other animals' olfactory neurons and suppresses breeding. Add it daily to a queenless colony and no new queen rises.
Across 123 populations, tree swallows all shift breeding one day earlier per degree of warming, yet northern birds are still falling behind and vanishing fastest.
Five years before they were ever diagnosed, the people who would go on to develop type 2 diabetes already carried the warning in their gut bacteria.
In a double-blind trial, capsules of donor gut bacteria sped up how quickly a common antidepressant lifted people's mood.
A blood measurement of a single tau fragment matched costly brain scans at spotting Alzheimer's pathology in adults with Down syndrome, a group that almost always develops the disease but is rarely offered the newest tests.
Frozen mid-break-in, a malaria parasite has finally revealed the exact molecular hook it drives into a red blood cell to force its way inside.
In old mice, a swell of gut microbes jams the vagus nerve's line to the brain, and quieting them brings memory back.
A single drip permanently switches off a liver gene, and a year later the cholesterol is still down.
A rice protein rearranges the fats in a cell's outer skin within minutes of a heat spike, buying protection long before the plant can switch on new genes.
Scientists rewired a common gut microbe into a living sensor that reports, through fluorescence, when the intestine stops absorbing properly.
Tracking a radioactively tagged pesticide through a honey bee colony, researchers found the hive filters out most of it, until the defenses are overwhelmed and the queen starts loading what remains into her eggs.
Chinese researchers built an injectable molecule that stays dark until it reaches a scarring kidney, then switches on and clears into the urine, flagging fibrosis that standard blood tests miss.
A study of more than 2,000 pregnancies links depressive symptoms to shifts in the maternal gut microbiome, and transplants into germ-free mice suggest those microbes help shape the fetal brain. A butyrate supplement partly reversed the damage.
