Layer 6b silencing left the hours of sleep intact and thinned its depth
Chronically silencing a deep cortical layer in mice changed the electrical texture of sleep without changing how much of it there was. The result places layer 6b on the path by which orexin reaches the cortex, and it rests on 7 control and 9 silenced animals, all male, with a genetic handle that also labels neighbouring cells.
OpenAI had the proof checked in Lean; who checked the Codex logs?
A formal proof language can certify that a proof is correct. It cannot say which prompts an agent read before writing it, and that is exactly where the dispute sits.
Taiwan's factories are carrying a 16.75 per cent cost rise that shoppers do not see
Producer prices in Taiwan rose 16.75 per cent over the year in August while consumer prices rose 2.04 per cent. The imported cost arrives at the border and stops before the shop shelf, which puts the question of whose balance sheet holds it in front of the price data.
The consent line is drawn; which document shows whose voice was taken?
Article 4 makes consent the boundary of infringement and Article 7 gives the provider a duty to act on notice. Both can stop the harm; the document that would show whose voice a synthesis came from is not named in the text.
The ESR1 mutation in blood moved the switch forward; the survival question stayed put
The FDA's accelerated approval of Etcamah lets a blood test decide when to change hormone therapy in advanced breast cancer, ahead of the scan. The trial behind it reports a median of 16 months before the cancer worsened against 9.2 months, and the agency's own director says additional evidence is needed to confirm clinical benefit.
Washington's Iran aviation list reaches agents in Türkiye, the Emirates and Malaysia
OFAC put 27 Iranian airlines on the list in one action and suspended three aviation authorisations alongside them. The change that asks someone to behave differently sits with cargo and procurement agents in Türkiye, the Emirates, Malaysia and Kazakhstan.
WeChat's glasses pay and its assistants talk; what is stored afterwards?
Paying with a swipe on a glasses temple, and letting assistants open the conversation between themselves, shrink the user's part to a single approval. Both notices give a limit and a placement; neither gives a retention period.
Which balance sheet carries a 5.2 per cent spending plan on 3.0 per cent income?
In the New York Fed's August survey the mean probability of higher unemployment reached 44.4 per cent, expected spending growth rose to 5.2 per cent and expected income growth stayed at 3.0 per cent. The extra 100 billion dollars US drivers have paid for fuel since late February shows where the difference between those two numbers is going.
Which order could stop a Bombardier sale?
Trump's Monday post sets out a demand but names no authority. Bombardier's jets are built in Canada, the United States and Mexico, employ 3,500 people in Kansas and satisfy the rules of the agreement the president signed in his first term. The one concrete instrument taking effect on Tuesday is Canada's 20 billion dollar retaliatory tariff.
Who handed the platform the ad it removed?
Meta removed hundreds of AI generated child abuse ads and TikTok deleted dozens of AI remixed propaganda videos. In both files the same step starts the removal: an outside research group named the items one by one first.
