Sometimes the path to smarter machines begins with a single photon making a different choice. In a new study in the journal “Advanced Photonics,” an international team shows how a photonic quantum convolutional neural network, or PQCNN, can be built from existing hardware and gently steered by a simple adaptive trick called state injection. The result is a light based quantum network that classifies tiny images with better than 90 percent accuracy while using far fewer operations than its classical cousins.

Feeling too sick to socialize might not just be exhaustion talking. According to new research, it is a precisely wired conversation between the immune system and a specific set of brain cells that tells animals to pull away from the group. In a study published in Cell on November 25, 2025, scientists at MITs Picower Institute for Learning and Memory and collaborators at Harvard Medical School describe how the immune molecule interleukin 1 beta (IL 1β) acts on IL 1 receptor 1 expressing neurons in the brains dorsal raphe nucleus to shut down social behavior in mice.

A grey seal pup has just 17 days to drink its way into a dangerous ocean, and its mother’s milk is wired for that deadline. In a new Nature Communications study, researchers at the University of Gothenburg show that Atlantic grey seal milk carries roughly one third more distinct sugar molecules than human breast milk, including many giants never seen before, and that its chemistry shifts in lockstep with the pup’s crash course in survival.

You think you know why your dog acts the way they do, until a study like this yanks the ground a little. New research on more than a thousand golden retrievers shows that many of the same genes shaping human mood and intelligence are also steering fear, energy, and even aggression in these famously gentle dogs. Published in the Proceedings of the National Academy of Sciences, the work comes from a Cambridge-led team that sifted through nearly half a million genetic markers in golden retrievers and matched them against 14 everyday behaviors, from trainability to stranger-directed fear.

Half of the people who die by suicide never say a word about wanting to die. The silence around them feels ordinary right up until the moment it isn’t, and a new study from University of Utah Health suggests that this absence of signs is not simply a failure of screening or a missed diagnosis. It may reflect a different kind of biological risk altogether.

Some worries announce themselves in numbers, others in the way people talk. A new study from the SNF Agora Institute at Johns Hopkins University and Public Agenda suggests both are happening at once, revealing a country uneasy about its democratic future and unsure how to talk about it without retreating into familiar camps. The researchers did not go hunting for crisis.

A bowl of fermented cabbage sounds unremarkable until you watch immune cells shift their posture after weeks of eating it. In a 12 week clinical trial in Korea, researchers used single cell RNA sequencing to track how kimchi changes human antigen presenting cells and gently steers CD4 T cells toward balanced defensive and regulatory roles. The work, published in npj Science of Food, offers the most detailed look yet at how a traditional fermented food can tune the immune system without setting off alarm bells.

The idea that the brain begins its work long before the world touches it feels almost mystical, yet the evidence keeps arriving. Now a team led by UC Santa Cruz shows that human brain organoids produce structured electrical sequences with no sensory input at all, a finding that shifts how we think about the earliest steps toward thought. The work, published in Nature Neuroscience, probes a period of development normally sealed away inside the womb.

A mother's fading memory and a son's quiet heartbreak helped steer a basic research question in a very specific direction. Years after that conversation in rural Anhui, Rutgers neuroscientist Peng Jiang and his collaborators report that a rare gene variant can help human microglia resist Alzheimer’s related tau pathology. The work, published in Nature Neuroscience, focuses on a trisomy 21 associated mutation once linked to leukemia risk in Down syndrome and reframes it as a potential source of resilience.

The same molecular playbook that taught our cells to fight a pandemic is now being tested against snake venom that melts human muscle. In a new preclinical study in Trends in Biotechnology, scientists from the University of Reading and the Technical University of Denmark report that intramuscular delivery of mRNA wrapped in lipid nanoparticles can prompt muscle cells to make their own venom blocking antibodies and blunt tissue damage from a notorious viper toxin.

Before a young orangutan ever forages alone in the forest, its mind is already carrying a crowded library of cultural knowledge. A new study in Nature Human Behaviour, led by researchers at the Max Planck Institute of Animal Behavior and based on 12 years of field data from Sumatran orangutans, shows that this library does ...

On the floor of the South Atlantic, a 61 million year old pile of broken lava is quietly drinking carbon from the sea. In a study published in Nature Geoscience, a team led by the University of Southampton shows that rubble left behind by collapsing seafloor mountains can lock away seawater derived carbon dioxide for tens of millions of years.

A quiet brilliance runs through the skin long before birth, a kind of mechanical intuition that seems to know how to pull damaged tissue back together. In new work from Yale School of Medicine, researchers traced this instinct to some of the earliest choices made by embryonic skin stem cells, using zebrafish embryos and human skin models to understand how the body learns to heal.

For years, close orbiting exoplanets that seemed drenched in water were treated as cosmic migrants, born far from their stars and hauled inward later in life. A new set of laser driven experiments suggests something more startling. Dry, hydrogen rich worlds can manufacture oceans from the inside out, rewriting how scientists connect a planet’s water supply to its birthplace. In work led by Lawrence Livermore National Laboratory postdoctoral researcher Harrison Horn and published in Nature, researchers recreated the brutal conditions at the boundary between a rocky, molten core and a thick hydrogen atmosphere on sub Neptune sized planets.

A surprisingly small circle of social media users can reshape an entire country’s political divide, and Finland offers a vivid case study. In a new paper in the journal Network Science, researchers from Aalto University use Twitter data from the 2019 and 2023 Finnish parliamentary elections to show that elite accounts contribute far more to online polarization than their numbers would suggest.

The first moment you hear about a fingertip bandage that lets you feel digital textures, something in you tilts toward disbelief, then curiosity. Northwestern University engineers say their new wearable device, called VoxeLite, can finally match the spatial and temporal acuity of the human fingertip, a claim that carries surprising weight in Science Advances and pushes the field of haptics into territory it has chased for decades.

A new study lands with a thud of inevitability, the kind that makes you wonder how the field missed it for so long. Published in Science Translational Medicine, the work argues that Epstein Barr virus is not just associated with lupus but may actively rewire a tiny subset of B cells into inflammatory agitators that rouse the immune system against the body itself.

You can almost feel the paradox tightening like a knot, cancer cells using the very signals meant to kill them to climb back toward life. In new work from the University of California San Diego, researchers report that drug-stressed tumor cells co opt a death linked enzyme and use it to regrow, a discovery that reframes early treatment resistance and opens a fresh therapeutic target.

A small shift in theory can sometimes make a machine see more clearly. Researchers at Rice University and Oak Ridge National Laboratory now suggest that by rethinking how water molecules move around MRI contrast agents, sharper scans and safer diagnostics may come within reach. Their new physics based model, published in The Journal of Chemical Physics, offers a microscopic account of magnetic resonance relaxation that earlier approximations could only gesture toward.

Imagine a bandage-like strip on your skin quietly turning humidity, breath and body heat into electricity for your devices. In a new study in the journal Wearable Electronics, a team led by researchers at Nanjing University reports a flexible evaporation-induced generator that uses a carefully engineered “water-ion-temperature” gradient to reach a peak power density of ...

The moment the pressure rises into the realm where atoms start second guessing their loyalties, gold reveals a side of itself that almost never emerges on Earth. A new study from Lawrence Livermore National Laboratory, published in Physical Review Letters, captures that transformation with unusual clarity, pushing the metal to pressures that approach the interiors of giant planets and watching its crystal structure reorganize in real time.

The mountain West has always made a sport of humbling forecasters, its snowpack shifting with every canyon kink and wind-scoured ridge, its storms producing featherlight powder one day and soggy concrete the next. In new research from the University of Utah, scientists try to bring order to this unruly world by teaching an algorithm to understand the snow-to-liquid ratio, the deceptively simple number that decides how much snow actually piles up.

In the clouded mountain forests of Central and South America, some of the fiercest duels are fought with beaks that double as spears. In a new study led by scientists at the University of Washington’s Burke Museum and published in the Journal of Experimental Biology, researchers show that male green hermit hummingbirds have evolved bills that are not just for sipping nectar, but for stabbing rivals during high stakes mating battles.

Attacks on cargo ships in a narrow Middle Eastern strait have ended up changing the brightness of clouds half a world away. In a new study in the journal Atmospheric Chemistry and Physics, Florida State University atmospheric scientist Michael Diamond and graduate student Lilli Boss show that cleaner marine fuel has sharply weakened shipping’s ability to seed reflective clouds, even when ship traffic surges.

The problem might not be brain damage after all. New research tracking the same group of Navy Seabees over two decades suggests that Gulf War illness stems from a persistent energy crisis inside brain cells rather than irreversible neural destruction. In a study published in Scientific Reports this month, researchers led by Sergey Cheshkov and Robert W. Haley at UT Southwestern Medical Center used advanced brain imaging to show that veterans with Gulf War illness have mitochondria stuck in a state of chronic dysfunction.
