A More Expressive Brain Implant, EU Cyber Rules and Climate Feedbacks
This briefing covers a brain implant decoding speech and gestures together, new EU reporting deadlines for exploited vulnerabilities, estimated warming from natural emissions, South Korea's expanded espionage law, mRNA nanoparticles that altered tumour-supporting immune cells in mice, and a revised estimate of Mercury's contraction.

One Brain Implant Decodes Words and Gestures Together
A 253-electrode brain implant decoded attempted speech and upper-body gestures at the same time, allowing two people with severe paralysis to control text and movement through a digital avatar. Separate machine-learning systems handled both channels, and combined training reduced missed signals and false activations. The proof of concept involved only three participants, restricted vocabularies and wired external equipment. It did not produce unrestricted conversation, and safety, durability and independent home use remain untested.

EU Manufacturers Face a New Cyber-Reporting Clock
Manufacturers selling connected hardware or software in the European Union must now report actively exploited vulnerabilities and severe product-security incidents through ENISA's common portal. An early warning is required within 24 hours, followed by fuller notification. The system centralizes reports across national response teams, but it does not itself fix products or guarantee timely detection. Most wider Cyber Resilience Act duties, including obligations for open-source stewards, do not apply until December 2027.

Natural Emissions Could Add More Warming This Century
A new analysis estimates that emissions from thawing permafrost, wildfires, wetlands and inland waters could add 0.2°C to 0.4°C of warming by 2100. Most policy models do not represent all four feedbacks together, which could make remaining carbon budgets smaller than they appear. The estimate combines process studies with a reduced-complexity climate model and carries wide uncertainty. The higher value is not inevitable, because cutting human emissions also limits these natural feedbacks.

South Korea Broadens Its Espionage Law
South Korea's expanded espionage offence now covers qualifying conduct performed for any foreign country or comparable organization, rather than focusing the general provision on North Korea. The government says the change strengthens protection for semiconductors, displays, batteries and artificial intelligence. Prosecutors must still prove that the information was a national secret and that the accused acted through direction or communication with a foreign entity. The law's practical reach will depend on future investigations and court interpretations.

mRNA Nanoparticles Reprogram Immune Cells in Mouse Tumours
Researchers used antibody-guided lipid nanoparticles to deliver mRNA and an immune stimulant into tumour-associated macrophages in mice. Suppressive macrophages fell by more than 60%, while the signal CXCL9 rose fourfold and attracted more cancer-fighting T cells. Tumour growth declined moderately, but adding checkpoint drugs did not improve control further in this model. This remains an animal study, with human safety, delivery, manufacturing consistency, durability and any survival benefit still unresolved.

Mercury May Have Contracted More Than Its Surface Shows
A correction for rough, impact-covered terrain suggests Mercury may have contracted 10% to 30% more than earlier surface mapping indicated. Some cliffs and ridges may be buried, harder to recognize or less likely to form in broken terrain, raising the estimated diameter loss to up to 23 kilometres over billions of years. This is a model-based geological correction, not direct observation of current shrinkage. BepiColombo's sharper mapping may confirm, narrow or revise the estimate.
