The work shows how chirality—the property of a molecule not coinciding with its mirror image—turns a weak magnetic signal into a reliable compass. Chirality does not merely create quantum coherence, but induces spin polarization, forcing the system to endlessly 'freeze' in one state. This amplificat

A new method uses light to shine through thin brain slices and deep learning for automatic analysis. The DenseNet121 neural network identifies structural changes with 88% accuracy, speeding up diagnosis and reducing the risk of error. The technology will aid in early detection of tumors and other pa

A diamond plate with 49 DNA sensors catches disease marker molecules. When the target is caught, the magnetic noise quiets, and the sensor gives a signal—fast, with no reagents or bulky equipment.

Biological processes depend on magnetic fields inside cells. A new method uses paired laser flashes to see invisible chemical 'dances' in living systems—a step toward portable sensors.

By comparing the glow of healthy and cancerous brain cells, scientists discovered different flickering patterns. This is a step toward diagnosis without surgery.

Scientists have figured out how birds navigate by the magnetic field. In their eyes, a protein called cryptochrome, under blue light, spawns a pair of field-sensitive particles. Their behavior shifts with the field's direction, and the protein generates an electrical signal. The bird's brain turns i

Scientists have proved: purely quantum systems cannot become agents. To make plans and decisions, you need to copy information about the world, and the quantum no-cloning theorem puts an end to such attempts. The mind requires classical 'parts'. This explains how familiar behavior emerges in a quant

Scientists have determined how many computational operations Physarum polycephalum — a slime mold devoid of neurons — can perform. By analyzing its growth and shape changes, they applied the physical limit of computation speed imposed by energy. It turns out that in a day, this blob of slime perform

Scientists have figured out that not every star is fit for 'cooking' life. By comparing the ultraviolet balance of different suns, they determined: the ideal recipe is found in yellow G-class stars like the Sun. Only there does the ratio of soft to hard radiation allow molecules to complexify into i

Ordinary computer calculations miss quantum phenomena that are crucial at the nanoscale. Inside the cramped viral shell, the DNA thread behaves like a wave. By applying the mathematics of the microworld to the Paracoto virus, researchers discovered that quantum effects here are not a minor detail bu

Plants and birds have mastered quantum tricks for survival: perfect photosynthesis and navigation without maps. Now engineers are copying these lessons for future technologies.

Scientists have turned a diamond with a microscopic defect into an ultrasensitive sensor. It measures how quickly the magnetic response of hydrogen nuclei in cells decays. Each cancer line has its own rate — like a fingerprint. The method requires no staining and paves the way for gentle diagnostics

Scientists have discovered that a tiny carbon molecule, while spinning, can exist in two states at once — like a coin showing heads and tails simultaneously. Thanks to its mass, it maintains this quantum weirdness for a long time, even inside a warm cell. This molecular spinning top is exquisitely s

The 'Agent Choice via Quantum Flux' model reconciles free choice with physics: one decision is embodied by many quantum states—like soup made by different chefs. This leaves room for genuine choice where only predetermination was seen before.

Scientists simulated how bacteria avoid dangerous 'short circuits' during photosynthesis. It turns out they use a quantum filter called CISS, which lets through only electrons with the correct spin direction, preventing cell destruction.
