Science Digest - When Tumours Hijack Nerves
Some days the pattern is clear: progress comes from better control. Better control of cells. Better control of qubits. Better control of rockets on the pad.
Breakthrough of the Day - Tumours hijack a tumour-to-brain circuit to suppress immunity
A striking mouse study mapped a feedback loop where lung tumours recruit nearby sensory neurons, connect into them, and use that signalling to reduce anti-tumour immune activity at the tumour site. When researchers genetically inactivated the relevant sensory neurons, tumour growth dropped by more than half.
If the same kind of circuit exists in humans, it suggests a new therapeutic angle that sits next to immunotherapy rather than replacing it: disrupt the neural signalling that is helping the tumour hide, and you may restore immune pressure locally.
Medicine and Biotech - A more selective CAR-T that could spare healthy B cells
CAR-T therapies have been transformative in some blood cancers, but the standard target (CD19) is blunt: it wipes out healthy B cells along with malignant ones, which can leave patients immunosuppressed and vulnerable to infection.
A new approach described by Nature targets a much narrower marker: B cell receptors carrying IGHV4-34, which appears enriched in certain cancer cells and rare in healthy B cells. In mouse models of diffuse large B cell lymphoma, CART4-34 matched the tumour-killing effect of CD19 CAR-T while avoiding healthy B cells. The same selectivity could matter for autoimmune disease too, because IGHV4-34-associated antibodies show up in some forms of lupus.

Space - Artemis II slips to March after wet dress rehearsal issues
NASA completed a full cryogenic propellant loading test for Artemis II but hit a liquid hydrogen leak that required hours of troubleshooting. During terminal countdown operations, the ground launch sequencer stopped the countdown after a spike in the leak rate. Teams also dealt with a hatch pressurization valve needing re-torquing, closeout work that took longer than planned, and intermittent ground audio communication dropouts.
NASA now targets March as the earliest launch opportunity, with another wet dress rehearsal planned after data review.

Engineering - Quantum computers may become practically useful within a decade
Quantum computing has always had a credibility gap: beautiful theory, fragile hardware. Nature reports a noticeable shift in researcher expectations driven by concrete progress on error rates, control techniques, and quantum error correction demonstrations that show logical qubits can be improved below key thresholds.
The near-term headline is not that a universal, fault-tolerant machine is here. It is that multiple groups have now shown the core scaling trick (error correction) can work in practice, and algorithmic improvements are steadily reducing the qubit counts needed for high-value tasks.
Neuroscience and Law - Mapping white matter injury patterns tied to impulsive violence
As brain imaging becomes more detailed, courts increasingly see neurological evidence offered to explain violent criminal behavior. A new line of work argues that the next step is network-level mapping: not just where a lesion is, but which decision-making and emotional regulation circuits it disrupts.
The Conversation summarizes research linking damage to a white matter tract called the right uncinate fasciculus (connecting the amygdala and orbitofrontal cortex) with post-injury criminal behavior in a set of published medical cases. If this approach holds up, it could sharpen both clinical understanding and legal interpretation of brain injury claims.
