OpenAI says its AI models produced findings in harmonic analysis, computer science and physics. The company reported proofs addressing a long-standing mathematics conjecture and claims involving computational complexity and quantum chromodynamics, while noting that outside researchers are reviewing the work.
Key Facts
OpenAI said its models proved the local smoothing conjecture in every spatial dimension; researchers had previously proved it only in three dimensions.
The local smoothing conjecture is a problem in harmonic analysis, which studies how signals and functions can be represented using waves.
OpenAI said its models disproved the Exponential Time Hypothesis, a claim about how long it takes to solve certain computational problems.
The company said its models gave a mathematically rigorous proof of the existence of quantum chromodynamics, the theory of interactions between quarks and gluons.
Alex Iosevich, a University of Rochester mathematics professor, described the reported proof of the conjecture as a historic development.
OpenAI said it consulted three expert groups, called “shepherds,” on how to review and release the findings.
The mathematics and computer science groups chose to make AI-produced data public immediately; the physics group deferred its release to prepare an interpretation.
OpenAI said the findings need further scientific interpretation and welcomed feedback on broadening participation in the process.

An Open Rights Group report says the Home Office uses or tests AI in immigration work, including border surveillance, asylum case support and case prioritisation. The group argues that limited transparency and risks of bias could harm migrants’ rights, and calls for tighter regulation and disclosure. The Home Office says AI assists staff but does not make asylum decisions, and says it monitors the tools.
Key Facts
The report is titled “Automated Discrimination: Unpacking the Digital Hostile Environment.”
The report says AI is used or tested to identify potential sham marriages, help assess asylum seekers’ ages and examine the contents of some phones.
It says AI tools are used in border surveillance and to summarise asylum interviews and policy information.
The report identifies the Identify and Prioritise Immigration Cases tool as a way to prioritise and assess cases.
Open Rights Group gathered information from Home Office publications, freedom of information requests and parliamentary questions.
Open Rights Group calls for stronger AI regulation, greater transparency, changes to freedom of information laws and a public register of government AI tools.
The Home Office says trained caseworkers make asylum decisions and AI tools only assist them; it says it monitors the tools and plans to publish updated evaluations.
Labour MP Bell Ribeiro-Addy, SNP MP Pete Wishart and Green Party peer Siân Berry support the report.

Medical historian Lindsey Fitzharris’s new biography, *Sleuth-Hound*, examines Scottish surgeon Joseph Bell, who taught Arthur Conan Doyle at the University of Edinburgh and helped inspire Sherlock Holmes. The article describes Bell’s skill at inferring details about people from their appearance and highlights how his empathy and other traits differed from the fictional detective.
Key Facts
Joseph Bell was a surgeon at the University of Edinburgh and taught Arthur Conan Doyle when Doyle was a medical student.
Bell could infer details about people’s health, work, and habits by observing clues such as a limp, a callous, or a stain.
Bell once identified the route a patient had walked by studying the clay on the patient’s boots; Doyle used the incident in *The Sign of the Four*.
Bell worked with a local police surgeon on prominent murder cases of his era.
Medical historian Lindsey Fitzharris wrote *Sleuth-Hound: The Case of the Real Sherlock Holmes*.
Fitzharris said Bell was deeply empathetic, unlike the common image of Sherlock Holmes.
Fitzharris is also the author of biographies of surgeons Joseph Lister and Harold Gillies.

More than 300 Boston Dynamics employees signed a petition asking executives to stop a sale of modified Spot robot dogs to ICE. The company defended the deal, saying the robots can help keep people safe and would not be weaponized; the $1.3 million contract covers four robots intended for inspection and observation tasks.
Key Facts
Employees sent the petition to Boston Dynamics executives in early September, before the contract was awarded on September 25.
The petition’s more than 300 signatories represent about half of the company’s approximately 1,400 workers; roughly half of the signatures were anonymous.
The Department of Homeland Security contract awarded $1.3 million to Connecticut-based Radeco to provide ICE with four modified Boston Dynamics Spot robots.
Radeco’s modified robots are marketed as Cerberus and are equipped with radiation and gas sensors, cameras, and infrared thermal imaging.
The contract describes uses including detecting hazards, inspecting confined spaces, and supporting remote observation missions.
The robots can navigate complex industrial environments and perform repeatable autonomous missions with limited human intervention, according to the contract.
Boston Dynamics said ICE’s Homeland Security Investigations unit would primarily use the robots; the article notes that the unit has also conducted deportations and workplace raids.

Since June, thieves have stolen more than $100 million in cargo bound for data centers, using hacked freight accounts, fake driver credentials and GPS spoofing, according to NBC News. Investigators say some thefts involved staged crashes that separated escort vehicles from trucks carrying valuable equipment.
Key Facts
The stolen cargo has included servers, fiber-optic cables, computer memory chips, copper wire and bitcoin mining machines.
Thieves reportedly hack freight brokers’ accounts, post fake shipments and send malicious links to trucking companies that respond.
After gaining access to trucking accounts, thieves can bid on real shipments and arrange for cargo to be transferred to accomplices.
The Cook County Sheriff’s Office estimated that two stolen Illinois shipments contained about $300,000 in copper wire and roughly $1 million in data center power equipment.
A shipment carrying server equipment valued at $13 million was stolen after a car struck the vehicles of two off-duty police escorts.
In another theft, a truck carrying server rack components valued at about $10 million escaped after an SUV struck its escorts’ vehicle.
Investigators said location-tracking coordinates in the second case appeared to have been spoofed.

Researchers at NYU Langone Health reported that a blood test tracking tumor DNA detected signs of lung cancer recurrence before standard scans in some patients. In a retrospective study of 42 patients, the test had 75 percent sensitivity and 83 percent specificity; researchers said larger prospective studies are needed before it guides routine care.
Key Facts
The study examined recurrence after surgery, not screening people who had never been diagnosed with lung cancer.
Researchers used blood samples to track circulating tumor DNA, genetic material released by cancer cells.
Among patients whose blood test turned positive before recurrence was detected, the median lead time was 16.7 months.
The study focused on patients with stage IA lung adenocarcinoma.
The test's sensitivity was 75 percent, meaning it detected 75 percent of observed recurrences in the study.
The test's specificity was 83 percent, meaning it correctly identified 83 percent of patients without the measured recurrence.
The researchers described the study as retrospective and said larger studies with regular blood-draw schedules are needed before the test can guide routine clinical decisions.
