   A Washington state resident dies of bird flu caught from dairy cows, the first US bird flu death in a year

   3

   people in the US who have died of bird flu since 2024

   the others died in Louisiana in January 2025 and in Washington in November 2025 [1]

   33

   dairy herds in Yakima County with bird flu since early October

   3 people in the county caught it at a dairy [2]

   72

   human cases of bird flu counted in the US since 2024

   no spread from one person to another is known [1]

   What happened

   • A person in Washington state, in the US, has died of bird flu caught from infected dairy cows. [1]
   • It is the first bird flu death in the US in a year. [1]
   • The person lived in Yakima County and had other health problems. [2] They were taken to hospital very ill, and died on Sunday, 1 November. [2]
   • 33 dairy herds in Yakima County have tested positive for bird flu since early October. [2]
   • 3 people in the county have caught it from infected cows at a dairy. [2]
   • The third case was announced on Sunday. [2] That person was not badly ill and did not need hospital care. [2]
   • The CDC read the genes of the virus from the person who died. [1] It found no change that would help it spread more easily or harm more. [1]
   • No one in the US is known to have passed this bird flu to another person. [1]
   • The CDC has counted 72 human cases of bird flu in the US since 2024. [2]

   Who is involved

   The CDC, the US national public health agency, said the virus was H5N1, a bird flu that also infects cattle. [1]

   The Yakima Health District, the county's public health office, announced the death. [2]

   • The CDC the US national public health agency; it confirmed H5N1 and read the virus's genes
   • Yakima Health District the public health office of Yakima County, Washington; it announced the death and is tracing contacts
   • Washington State Department of Health the state's health agency; it is helping to find and watch close contacts

   How it unfolded

   2 other people in the US have died of bird flu since 2024, so this is the third. [1]

   An elderly person in Louisiana died of H5N1 in January 2025. [1] A person in Washington died of a rarer kind, H5N5, in November 2025. [1]

   1. Jan 2025 first US bird flu death, in Louisiana [1]
   2. 1 Nov a Yakima County resident dies of H5N1 [1]
   3. Nov 2025 a Washington resident dies of H5N5 [1]
   4. Nov 2025 Washington, H5N5
   5. 1 Nov Yakima County, H5N1
   6. Early 2024 bird flu spreads among US farm animals [1]
   7. Early Oct Yakima dairy herds start testing positive [2]

   Why it matters

   The CDC says the risk to the general public is low. [1]

   How it works

   Disease trackers call this exposure: being close to a germ. [1] The more animals carry bird flu, the more chances people get to catch it. [1]

   Yakima has 33 infected herds. [2] All 3 people infected there caught it from cows at a dairy. [1]

   Seen it before

   A child who sits beside more coughing classmates is more likely to catch a cold.

   The truth

   • Yakima County officials released no other details about the person who died. [1]
   • Who pays Dairy workers in Yakima County — Their work puts them close to infected cows, which officials say makes them the people most at risk. [2]
   • Nobody knows yet

     Whether more people in Yakima County will catch bird flu.

     The third case there was found only on Sunday, and health workers are still finding and watching the close contacts of all 3. [2]

1. 02

   A cheap copy of an HIV shot is cleared

   What happened

   • The FDA, the US drug regulator, gave a tentative approval to a cheap copy of an HIV prevention shot. [3]
   • The shot, lenacapavir, is given once every 6 months and protects almost completely against catching HIV. [3]
   • Dr Reddy's plans to start shipping the shot next month. [3] Global health groups have pushed to get it to poorer countries as fast as possible. [3]
   • It will cost $40 a person a year, about the same as daily HIV prevention pills. [3]

   Who is involved

   The copy is made by Dr Reddy's, one of the world's biggest makers of generic, or copied, medicines. [3]

   • Dr Reddy's a big maker of copied medicines

   How it unfolded

   Gilead Sciences, which sells the original in the US as Yeztugo, won FDA approval for it last year. [3]

   1. Last year Gilead's original approved
   2. Now a copy gets tentative approval

   Why it matters

   The approval is a key step to widening use in dozens of low- and middle-income countries, STAT reports. [3]

   AP reports the copy is meant for 120 low- and middle-income countries. [30]

   How it works

   The FDA calls an approval tentative when a copy meets its standards but the original is still under patent. [30]

   So Dr Reddy's copy cannot be sold in the US. [30] But FDA approval can speed approval in many other countries. [30]

   Why the FDA can stop one trial and move its own deadline

   People in regulatory affairs, who steer medicines through approval, know the FDA acts at every stage, not only with a final yes or no.

   The twist

   The FDA can stop one trial of a drug while its other trials go on. It can also move its own decision date when new data arrives during a review.

   The picture

   Bright Minds49%

   Agios18%

   uniQure3%

   Step by step

   1. 1 A new drug must pass separate checks: safe to test, works, made right
   2. 2 The FDA answers each check when it comes up, not all at the end
   3. 3 A worry about one trial stops only that trial: a partial hold
   4. 4 Major new data during a review moves the decision date by 3 months
   5. 5 So each answer moves a company's money and a patient's wait

   The same force, elsewhere today

   Where this chain is also running, in today's other stories.

   • FDA halts part of a seizure-drug plan

     The FDA stopped only the US trial that would enrol children, because its worry was about young bodies, and Bright Minds' running trials go on.

   • FDA delays Agios's sickle cell pill

     Agios sent safety data the FDA had asked for, the FDA counted it a major change, and the decision date moved 3 months to 1 February 2027.

   • FDA sets a date for a Huntington's treatment

     The FDA accepted uniQure's application and set 1 May, but it still plans to ask outside experts before it decides.

   • A cheap copy of an HIV shot is cleared

     The FDA gave Dr Reddy's copy a tentative approval, a step short of a full one, and that step opens shipments to poorer countries.

   Where you've seen this

   Building sites

   an inspector can stop work on one floor while the rest of the building goes on

   Driving tests

   the theory test and the road test are passed separately, and failing one does not cancel the other

   School exams

   a re-mark of one paper delays only that result, not the others

   The catch

   Many of these answers stay private: Bright Minds learned the scope of its hold from an email, and the FDA's formal letter has not been sent yet.

   And the whole of it

   A US child with severe seizures, a sickle cell patient waiting until February and a Huntington's family waiting until May all depend on one agency's calendar. Each of them sees only the date for their own drug.

   The truth

   • Carolyn Amole, of the Clinton Health Access Initiative, says the money to buy it for everyone is not there yet. [30]
   • Who gains Dr Reddy's — It becomes a supplier of a shot that global health groups are pushing to get into poorer countries quickly. [3]
   • Nobody knows yet

     How fast the cheap HIV shot will reach the people who need it.

     The part of STAT's report we could read gives no countries and no numbers for the first shipments. [3]

   Good news

   • Dr Reddy's, one of the world's biggest makers of copied medicines, won a tentative US approval for its copy of lenacapavir, an HIV prevention shot given every 6 months. It plans to start shipping next month at $40 a person a year.

1. 03

   FDA sets a date for a Huntington's treatment

   What happened

   • The FDA will decide by 1 May whether to approve uniQure's gene treatment for Huntington's disease. [6]
   • Huntington's is an inherited brain disease that kills, and no treatment has yet been shown to slow it. [6]
   • The treatment is given in 1 dose, by brain surgery, into a deep part of the brain called the striatum. [6]
   • The FDA also plans to ask outside experts to discuss it at a meeting, with no date set yet. [6]

   Who is involved

   • Vinay Prasad former head of the FDA's biologics centre

   How it unfolded

   In November 2025 the FDA told uniQure its data might not be enough for approval. [6]

   The agency changed course after Vinay Prasad, the official who opposed the application, resigned this year. [6]

   1. Nov 2025 the FDA doubts the data
   2. Now the FDA accepts the application

   Why it matters

   uniQure's chief executive said Huntington's families have "waited generations for a treatment that changes the course of this devastating disease". [6]

   How it works

   Geneticists call this gene silencing: stopping a gene from making its protein. [6]

   The harmful protein in Huntington's comes from the huntingtin gene. [6] So silencing that gene cuts the protein at its source. [6]

   Seen it before

   Turning off a dripping tap works better than mopping the floor again and again.

   The FDA accepted uniQure's application and set 1 May, but it still plans to ask outside experts before it decides.

   The idea, in story 02: Why the FDA can stop one trial and move its own deadline →

   The truth

   • After 4 years, the trial's main measure showed a 44% slowing that was not statistically clear. [6] A measure of everyday function showed 61%. [6]
   • Who gains uniQure — The FDA is reviewing its treatment under priority review, which brings a decision sooner. [6]
   • Nobody knows yet

     When outside experts will discuss uniQure's Huntington's treatment, and what they will say.

     uniQure says only that the FDA will tell it when a meeting is set. [6]

   Good news

   • The FDA agreed to review uniQure's gene treatment for Huntington's disease, an inherited brain disease that no treatment has yet been shown to slow. It will decide by 1 May.

   What comes next

   uniQure plans to start screening patients for a US trial of about 200 people by the end of 2026. [6]

2. 04

   FDA delays Agios's sickle cell pill

   What happened

   • The FDA moved its decision on Agios's sickle cell pill, mitapivat, from 1 November to 1 February 2027. [7]
   • People with sickle cell disease, an inherited blood disorder, suffer painful attacks called pain crises. [7]
   • The FDA asked for more safety data, to decide whether the pill needs a special safety plan. [7]
   • Agios sent about 9 months of new safety data on 19 October, which the FDA counted as a major change. [7]
   • In the main trial, 41% of 138 patients on the pill had more haemoglobin, the oxygen carrier in blood. [7] Only 3% of 69 on a dummy pill did. [7]
   • Agios's shares fell nearly 18% on Friday, from $37.23 to $30.55. [7]
   • The pill is already sold for thalassaemia, another blood disorder, under the name Aqvesme. [7]

   How it unfolded

   1. 1 Nov the old decision date
   2. 1 Feb 2027 the new decision date

   Why it matters

   Investors worry the delay shrinks Agios's lead over Novo Nordisk, which plans to file a rival drug this quarter. [7]

   How it works

   Under PDUFA, a US law on drug review fees, the FDA sets a date to decide each drug. [7]

   When a company sends major new data during a review, the FDA can add 3 months. [7]

   Seen it before

   Hand your teacher extra pages the night before marking, and your mark comes back later.

   Agios sent safety data the FDA had asked for, the FDA counted it a major change, and the decision date moved 3 months to 1 February 2027.

   The idea, in story 02: Why the FDA can stop one trial and move its own deadline →

   The truth

   • The pill did not clearly cut pain crises: 2.6 a year on it against 3.1 on a dummy pill. [7]
   • Who pays Sickle cell patients waiting for mitapivat — Its launch for sickle cell could slip by about 3 months, an analyst at Leerink Partners says. [7]
3. 05

   FDA halts part of a seizure-drug plan

   What happened

   • The FDA has stopped a planned US trial of BMB-101, a seizure drug from Bright Minds Biosciences. [8]
   • The trial was for severe epilepsies called developmental and epileptic encephalopathies, and would have enrolled children. [8]
   • The FDA pointed to harm seen in mice, and too little data on how the drug acts in young bodies. [8]
   • The company announced the hold on Monday. [9] Its shares fell 49% before trading opened, to $28. [8]

   Who is involved

   • Children with severe epilepsies who the trial would have enrolled

   How it unfolded

   Earlier, 11 patients on the drug had 73.1% fewer seizures over 3 months. [8] Days later, in January, Bright Minds raised $175 million. [8]

   Why it matters

   Bright Minds says trials already running are not affected, so only the new US trial waits. [8]

   How it works

   Drug regulators call this a partial clinical hold: one trial is stopped while the drug's others go on. [8]

   Here the worry was about young bodies, so the trial that would enrol children was the one stopped. [8]

   Seen it before

   A referee can send one player off while the match carries on.

   The FDA stopped only the US trial that would enrol children, because its worry was about young bodies, and Bright Minds' running trials go on.

   The idea, in story 02: Why the FDA can stop one trial and move its own deadline →

   The truth

   • Bright Minds' account rests on an FDA email; the FDA's formal letter is due within 30 days. [8]
   • Who pays US children with severe epilepsies — The trial that would have given them BMB-101 cannot start until the FDA lifts the hold, and Bright Minds cannot say when. [8]
   • Nobody knows yet

     Whether the harm seen in mice was caused by BMB-101.

     Bright Minds says the finding was by chance, and the FDA has not published its own reasoning. [8]

4. 06

   Karyopharm goes bankrupt to sell itself

   What happened

   • Karyopharm Therapeutics, a US maker of a blood cancer drug, filed for bankruptcy on Monday so it can sell itself. [11]
   • It used Chapter 11, a US court process that shields a company from its lenders while it reorganises. [11]
   • In 2025 Karyopharm sold about $115 million of its drug, Xpovio, and lost $196 million. [11]
   • Its shares fell 83% to 11 cents, valuing the whole company at $2.5 million. [11]

   Who is involved

   Ayrmid, an Irish company with 2 approved blood-disease treatments, will be the first bidder in a court-run auction. [10]

   • Ayrmid Irish maker of blood-disease treatments

   How it unfolded

   In May the FDA withdrew Xpovio's fast approval for a type of lymphoma, a blood cancer. [10] In July it failed a big trial in womb cancer. [10]

   1. May a lymphoma approval withdrawn
   2. July a womb cancer trial fails

   Why it matters

   Karyopharm says the process will not disrupt its work or its support for patients. [12]

   Ayrmid's chief executive, Joe Wiley, said it wants to "continue delivering important therapies to patients in need". [11]

   How it works

   Investors call the months a company's cash will last its runway. [10]

   Karyopharm spent more than Xpovio brought in, and early this year it said its cash would last only to mid-2026. [11]

   Seen it before

   Pocket money that runs out before Friday means borrowing, or selling something.

   The truth

   • Who gains Ayrmid — As first bidder it sets the starting price for Xpovio, a cancer drug already on sale, which it can add to its own blood-disease medicines. [10]
   • Nobody knows yet

     How much Ayrmid will pay for Karyopharm.

     The terms of its offer were not disclosed, and other bidders can still join the court-run auction. [10]

   What comes next

   The sale is expected to close in early 2027. [11]

5. 07

   A fertility treatment sold without proof

   What happened

   • STAT, a US health news site, spent 8 months looking into a fertility treatment sold to women over 40. [13]
   • The treatment, mitochondrial replacement or MRT, puts a woman's DNA into a donor's egg with its own centre removed. [13]
   • Mitochondria are the tiny energy factories in cells, and the donor eggs' are younger. [13]
   • A Dutch woman called Wendy paid more than $30,000. [13] Her pregnancy test came back negative. [13]
   • The average age of IFG's MRT patients rose from 39.2 in 2022 to 45.6 in 2025. [13]

   Who is involved

   It is illegal in the US. [13] IFG, a company near Chicago, connects women to clinics abroad, such as one in Albania. [13]

   • IFG a US company that arranges treatment abroad

   How it unfolded

   MRT was first built to stop rare mitochondrial diseases passing from mothers to children. [13]

   Why it matters

   Women paid tens of thousands of dollars for a treatment with no published proof it helps them. [13]

   How it works

   Research seen by STAT shows older women's infertility mostly has causes other than worn-out mitochondria. [13]

   So giving an egg younger mitochondria leaves those other causes in place, and MRT fails for most older women. [13]

   Seen it before

   A new battery will not fix a phone whose screen is broken.

   The truth

   • What is really going on Outside the FDA's reach, a US company, IFG, sold older women an unproven fertility treatment through clinics abroad, and stopped advertising it only after STAT's questions. [13]
   • IFG says it is not a clinic and promised no one a pregnancy. [13] After STAT's questions, it removed MRT from its website. [13]
   • STAT also got unpublished data from a Ukrainian clinic that once did the most MRT. [14] Its reporter calls the results "the strongest refutation" of MRT for age-related infertility. [14]
   • Who pays Women over 40 hoping for their own child — One woman's contract with IFG cost $20,000 before medicines and donor eggs, for a treatment that research shows fails for most older women. [13]
   • Nobody knows yet

     How many babies have been born after MRT.

     Industry insiders estimate up to 200, IFG claimed 34 by February 2025, and IFG declined to give newer figures. [13]

6. 08

   Ebola deaths in Congo reach 5,372

   What happened

   • Congo's Ebola outbreak had killed 5,372 people by Friday, figures released on Sunday show. [15]
   • Just over half of the people diagnosed with it die: 51.6%. [15]
   • Congo had 10,414 confirmed cases by 30 October. [15]
   • It is caused by Bundibugyo, a rare kind of Ebola with no approved vaccine or medicine. [16]
   • Kenya and Uganda have each had 2 deaths, Africa CDC, the continent's health agency, says. [16]

   Who is involved

   • Kenya 2 deaths
   • Uganda 2 deaths

   How it unfolded

   On day 187 of this outbreak there were 10,060 cases. [19] West Africa's 2014 outbreak had 544 by day 186. [19]

   Why it matters

   The outbreak has spread beyond Congo, with cases in Uganda, Kenya and Nigeria. [15]

   How it works

   Epidemiologists count an outbreak as under control when 95% of new cases come from known contacts. [19]

   In Congo about 80% of new cases come from chains of spread nobody was tracking. [15]

   Seen it before

   A teacher can stop a cold spreading only if she knows who sat next to the sick child.

   The truth

   • Part of the latest jump in deaths came from correcting old records, not from a single bad day. [15]
   • Who pays Families in Congo's Ebola areas — Many of the sick never reach care: at least half of the deaths were in people never admitted to a treatment centre, AP reports. [19]
   • Nobody knows yet

     How many Ebola infections in Congo nobody has found.

     The counts include only confirmed cases, and tracers have lost track of most chains of spread. [15]

7. 09

   Nigeria's suspected Ebola cases test negative

   What happened

   • 2 people suspected of having Ebola in north-eastern Nigeria tested negative twice, Nigeria's disease agency said on Monday. [17]

   Who is involved

   • A Swiss woman, 42 Nigeria's only confirmed case

   How it unfolded

   Nigeria confirmed its first Ebola case in more than a decade on 23 October. [17]

   That case is a 42-year-old Swiss woman who had been to Uganda. [17] She and her husband went home to Switzerland on 26 October. [17]

   Why it matters

   Nigeria is Africa's most populous country. [16] Both suspected cases were in its north-east, away from the first case in Abuja, the capital. [17]

   How it works

   Outbreak teams call this isolation and contact listing: keep a possible case apart, and list everyone they met. [17]

   Nigeria kept the 2 people apart and listed their contacts until 2 rounds of tests came back. [17]

   Seen it before

   A child with a rash stays home until the doctor says it is not catching.

   Good news

   • Both results were negative, so Nigeria still has just 1 confirmed Ebola case. [17]

   A panel warns mpox is being neglected

   What happened

   • The Independent Panel for Pandemic Preparedness and Response says the world is ignoring known disease threats such as mpox. [18]
   • Mpox, first found in people 50 years ago in West Africa, has spread to more than 82 countries. [18]
   • There were more than 14,000 confirmed cases and 50 deaths in the first 9 months of 2026. [18]
   • A target to vaccinate 6.4 million people across Africa was missed by far. [18]

   Who is involved

   Helen Clark, a panel member who has held senior UN roles, said preventable health emergencies are a sign of failure. [18]

   • Helen Clark panel member, former senior UN official

   Why it matters

   The panel says weak local health care and missed warning signs let viruses spread beyond where they began. [18]

   The truth

   • Nobody knows yet

     Why Africa fell so far short of its mpox vaccination target.

     The panel blames too little preparation and investment, but the report as described gives no count of how many people were vaccinated. [18]

9. 11

   Pennsylvania's measles cases reach 1,398

   What happened

   • Pennsylvania's measles outbreak has reached 1,398 cases, the state health department says. [20]
   • Health workers have given 150,000 doses of MMR, the measles, mumps and rubella vaccine, since 1 August. [20]
   • The outbreak centres on Lancaster County's Amish, a religious group that keeps much of modern life away. [20]
   • A study found fewer than a third of Amish residents had the MMR vaccine. [20]
   • Almost two-thirds of Pennsylvania's cases are adults, the reverse of how measles usually spreads. [20]
   • In New York, 3 Amish schools face fines of $2,000 for each unvaccinated pupil. [20]

   Who is involved

   US health secretary Robert Kennedy Jr says Governor Josh Shapiro's team politicised the outbreak. [20] Shapiro blames Kennedy for stoking vaccine doubt. [20]

   • The Amish of Lancaster County a religious group living apart from much of modern life
   • Robert Kennedy Jr US health secretary
   • Josh Shapiro Pennsylvania's governor

   Why it matters

   All 5 people who died in Pennsylvania were unvaccinated by choice or too young for the vaccine, a newspaper reported. [20]

   The truth

   • Pennsylvania counts 5 measles deaths. [20] The CDC lists only 3 deaths across the whole US this year, out of 4,588 cases. [20]
   • Nobody knows yet

     How many Amish people in Lancaster County are vaccinated against measles.

     The Amish are a religious group, so governments are not allowed to track it, says Steven Nolt, a historian of the Amish. [20]

   Good news

   • Pennsylvania has given 150,000 doses of the measles vaccine since 1 August, more than 50,000 of them in October.

    FDA sets potency rules for gene therapies

    What happened

    • The FDA published final guidance, its official advice, for companies that make cell and gene therapies. [21]
    • It explains how to prove each batch is potent, strong enough to do its job, before a patient gets it. [21]
    • Many of these treatments are made for just 1 person. [21]

    Who is involved

    Karim Mikhail, who runs the FDA's centre for biological medicines, said patients deserve to know the product will work. [21]

    • Karim Mikhail head of the FDA's biologics centre

    How it unfolded

    It replaces advice the FDA gave in 2011. [21]

    1. 2011 the FDA's old advice
    2. Now final guidance replaces it

    Why it matters

    Patients getting these treatments often have cancers or rare diseases and no other option. [21]

    How it works

    Drugmakers call this potency testing: checking that each batch does what the medicine is meant to do. [21]

    The raw materials vary, so batches of the same treatment can differ, and each must be checked. [21]

    Seen it before

    A baker tastes each batch of dough, because no two bags of flour are quite the same.

    What comes next

    The FDA will explain the guidance in an online session on 10 December. [21]

    Squeezed bones help old mice live longer

    What happened

    • Squeezing the leg bones of old mice twice a week for 4 months made them live nearly 3 months longer. [22]
    • That is about 9 extra years for a person. [22]
    • The study, led from Southern Medical University, was published in late October in Cell Metabolism, a journal. [22]
    • Bone cells called osteocytes sense being pushed and pulled, and then release proteins that slow ageing. [22]
    • Mice whose osteocytes could not sense force died 105.5 days earlier than normal mice. [22]
    • The squeezed mice also had stronger bones, faster reflexes and sharper minds. [22]

    Why it matters

    Exercise is linked to longer lives, but scientists "have yet to figure out how exactly this works". [22] Bones may be part of the answer. [22]

    How it works

    Biologists call this mechanosensing: cells reacting to being pushed or pulled. [22]

    A protein called PIEZO1 lets bone cells feel force. [22] With it switched off, the mice aged faster. [22]

    Seen it before

    A doorbell rings only when someone presses it.

    The truth

    • It has not been shown in people; a Mayo Clinic expert called it a proof of concept in mice. [22]

    A drug clears an Alzheimer's protein in rats

    What happened

    • An experimental drug, cinaciguat, cut amyloid beta in the blood of old rats by about 50% in 2 weeks. [23]
    • Amyloid beta is a protein that builds up in the brains of people with Alzheimer's disease. [23]
    • LDL, the bad cholesterol, also fell to the levels of young rats. [23]
    • The study, by the University of Southern California, was published in the Journal of Biological Chemistry. [23]

    Who is involved

    • University of Southern California where the study was done

    Why it matters

    Drugs aimed at the brain for Alzheimer's have failed about 98% of the time in trials. [23] Reaching the liver is much easier. [23]

    How it works

    The liver cleans the blood through tiny holes in the cells lining its blood vessels. [23]

    With age the holes shrink, so more amyloid beta stays in the blood. [23] The drug reopened them. [23]

    The truth

    • It has only been shown in rats so far. [23]

    An implant removes extra blood sugar in mice

    What happened

    • Swiss researchers built an implant that turns extra blood sugar into a substance the body passes out in urine. [24]
    • In diabetic mice it kept blood sugar in check for 6 weeks, and the mice lost weight. [24]
    • It uses gold and platinum on graphite felt, with no living cells, and gets its power without wires. [24]
    • A skin sensor tells a phone when sugar is too high. [24] The phone then switches the implant on. [24]

    Who is involved

    The work, led by Martin Fussenegger at ETH Zurich, a Swiss university, was published in the journal Science. [24]

    • Martin Fussenegger ETH Zurich researcher

    Why it matters

    Insulin moves sugar into cells but does not remove the extra energy, which can turn into fat. [24]

    How it works

    Engineers call this closed-loop control: the device switches itself off once sugar is back in range. [24]

    That is meant to stop blood sugar from falling dangerously low. [24]

    The truth

    • It has not been tested in people yet. [24]

    High lung blood pressure linked to memory trouble

    What happened

    • Many people with pulmonary hypertension, high blood pressure in the lungs' blood vessels, report memory problems. [25]
    • Brain scans of 248 patients in UK Biobank, a big health database, showed lost brain tissue. [25]
    • The link between two brain areas used for memory, attention and planning was also weaker. [25]
    • Low oxygen, heart problems and medicines did not explain the changes. [25]
    • A gene variant, found in 1 in 4 patients, drives inflammation in both the lungs and the brain. [25]

    Who is involved

    A study led by Stephen Chan at the University of Pittsburgh links those problems to inflammation in the brain. [25]

    • Stephen Chan University of Pittsburgh doctor and researcher

    Why it matters

    The researchers say memory trouble is part of the disease and deserves attention. [25]

    The truth

    • Nobody knows yet

      Whether calming the inflammation would protect the memory of people with pulmonary hypertension.

      The study points to targets for future treatments, and none has yet been tested. [25]

    An AI tool for single-cell lab data

    What happened

    • 10x Genomics, which makes lab machines for studying single cells, launched an AI tool called Sentira Single Cell. [26]
    • It runs on Anthropic's Claude AI models, and scientists use it through a chat window. [26]
    • 10x's technology chief, Michael Schnall-Levin, says "what might have taken someone weeks before could take hours". [26]
    • A session costs about 12 credits, and a full analysis about 60. [26] New users get 100 free credits. [26]

    Why it matters

    Scientists who cannot write analysis code could ask questions of their data directly. [26]

    The truth

    • One early user, at the Dana-Farber Cancer Institute, says his lab now leans more on Anthropic's own Claude Science tool. [26]
    • Who gains 10x Genomics — Sentira is paid for with credit packs that customers buy, so each analysis is a sale. [26]

    A New York child dies of measles

    What happened

    • A child in Lewis County, in rural northern New York, has died after catching measles, state officials said on Monday. [27]
    • It is New York's first measles death in 30 years. [27]
    • Her order lets paramedics and midwives give measles vaccines, and lets nurses order tests. [27]
    • The CDC counted 4,588 measles cases across the US in 2026 by late October, more than double the 2025 total. [27]
    • Measles kills about 1 to 3 of every 1,000 people who catch it. [27]

    Who is involved

    • Paramedics and midwives may now give the vaccine
    • Nurses may now order tests

    How it unfolded

    Governor Kathy Hochul declared a disaster emergency in early October over measles in rural New York and nearby states. [27]

    1. Early Oct a disaster emergency
    2. Monday a child's death announced

    Why it matters

    Robert Kennedy Jr, the US health secretary, has cut the vaccines recommended for children by a third. [27]

    Hochul blamed the US government, calling the death "a devastating reminder of what's at stake". [27]

    How it works

    Public health experts say about 95% of people must be vaccinated to stop measles outbreaks. [27]

    The US stopped measles spreading at home in 2000. [27] Its vaccination rates have since fallen below 95%, and outbreaks have returned. [27]

    Seen it before

    A fire cannot spread across a field where almost all the grass is wet.

    The truth

    • A Guardian report on Monday counted 5 measles deaths in Pennsylvania this year. [20] Its report on Tuesday counted 6. [27]

    A diabetes pill tried with pancreatic cancer drugs

    What happened

    • In a small trial, 22 people with advanced pancreatic cancer took a diabetes pill, sitagliptin, alongside their chemotherapy. [28]
    • The results were published this week in a journal from the Nature group. [28]
    • Tumours shrank by a set amount in 8 of the 22 patients, a response rate of 36.4%. [28]
    • Tumours stopped growing or shrank in 86.4% of patients. [28]
    • Half the patients lived at least 12.5 months. [28]

    How it unfolded

    With standard chemotherapy, half of people with advanced disease live about a year. [28]

    Why it matters

    Pancreatic cancer is among the deadliest cancers: 12% of patients are alive 5 years after diagnosis. [28]

    How it works

    Pharmacologists call this drug repurposing: testing a medicine already sold for one illness against another. [28]

    AI models suggested sitagliptin blocks an enzyme, ribonucleotide reductase, that lets tumours resist gemcitabine, a chemotherapy drug. [28]

    Seen it before

    A key cut for your front door may turn out to open the shed too.

    The truth

    • The trial had no comparison group. [28] The authors say the results need bigger randomised trials to confirm. [28]

    WHO chief presses for the pandemic treaty

    What happened

    • Tedros Adhanom Ghebreyesus, head of the World Health Organization, urged countries on Monday to finish the pandemic treaty. [29]
    • He spoke at negotiating talks in Geneva, pointing to the Ebola outbreak in Congo and hantavirus. [29]
    • That part, PABS, sets how dangerous germs are shared, and who gets the vaccines and medicines made from them. [29]
    • Wealthy and developing countries still disagree on how it should work. [29]

    Who is involved

    • Tedros Adhanom Ghebreyesus head of the World Health Organization

    How it unfolded

    Countries adopted the Pandemic Agreement in May 2025, but left out how its key part would work. [29]

    1. May 2025 agreement adopted, key part left open
    2. Monday talks on the missing part

    Why it matters

    Tedros said "a pathogen threat anywhere can become a threat everywhere". [29]

    During COVID-19, he said, vaccines came fast, but many countries waited while others took more than they needed. [29]

    How it works

    Diplomats call PABS access and benefit-sharing: a country that gives samples gets a fair share of what is made. [29]

    A country that shares a new germ quickly helps others build vaccines. [29] The system is meant to share those vaccines fairly in return. [29]
