A cash program for pregnant women and babies in Flint, Michigan, halved newborn deaths, a JAMA Pediatrics study finds
Swipe up for the story ↑Scroll down for the story ↓
A program in Flint, Michigan, gives cash to pregnant women and new babies.
Deaths in a baby's first four weeks fell from 10 to 5 for every 1,000 born alive.
Deaths in the first week of life fell from 8 to 2 per 1,000.
Who is involved
Flint families
almost every family with a new baby in the city takes part
Why it matters
Mothers and babies in the US fare worse than in other rich countries, the program's 2025 study notes.
Why it matters
Income falls and costs rise in the months around a birth.
How it works
In public health, a family's income counts as one of the strongest forces on health.
How it works
The cash arrives during pregnancy, when income drops, and goes on housing, transport and nappies.
Seen it before
A pupil who skips breakfast struggles in class, and a meal fixes what extra lessons cannot.
The truth
The halving compares one city's 2025 with its own earlier years.
The truth
A separate US trial paid mothers $333 a month for four years.
What's really going on
In Flint, Michigan, newborn deaths halved after the city began paying cash to families before and after birth.
Who gains
Families with new babies in Flint
The monthly $500 arrives just as income drops after a birth, and the program's studies find steadier housing and better food.
Nobody knows yet
Whether Flint's halving of newborn deaths will hold.
The result compares one city's 2025 with its own earlier years, and its founder calls it an early finding.
Nobody knows yet
Which part of the cash did the work.
Families spent it on nappies, transport, housing and safe places for babies to sleep, and no source says which mattered most.
Good news
In Flint, Michigan, newborn deaths fell from 10 to 5 for every 1,000 babies born alive in 2025, after the city began paying cash to pregnant women and new families.

A ministroke raises dementia risk
Swipe up for the story ↑Scroll down for the story ↓
Even a ministroke is linked to a higher risk of dementia, a study in the journal Neurology finds.
A ministroke, or TIA, is a stroke that lasts only a few minutes.
The study followed 113,081 people, with an average age of 70, after a first ministroke.
They were compared with similar people with no stroke, and with people who had a full stroke.
Over about 7 years, 19% of the ministroke group got dementia.
After a ministroke, people were 2.5 times as likely to get dementia as to have a stroke.
Why it matters
Ministroke symptoms pass in minutes, usually with no damage a scan can see.
How it works
1 of 3
later have a severe stroke
The US brain-disease institute, NINDS, calls ministrokes warning signs of stroke.
How it works
A ministroke shares its causes with stroke, such as high blood pressure and smoking.
Seen it before
A smoke alarm that beeps once and stops still means something set it off.
The truth
The groups were matched on age, sex and health, so the study shows a link, not proof of cause.
Nobody knows yet
Whether a ministroke itself causes dementia.

NHS list overstates Palantir's reach
Swipe up for the story ↑Scroll down for the story ↓
NHS England lists 29 hospital trusts as gaining from its Palantir data system.
Who is involved
Palantir
US data company; runs the £330m platform
NHS England
lists the trusts gaining
Palantir is a US data company.
The answers came from more than 100 freedom of information requests by Medact, a medical charity that wants Palantir out.
How it got here
This summer NHS England admitted it could not prove the system caused 117,539 extra operations it had claimed.
What comes next
The Office for Statistics Regulation, the UK's statistics watchdog, says it will now look into the claim.
Why it matters
Chi Onwurah, who chairs a Commons science committee, wants the contract's 2027 break clause used to end it.
How it works
NHS England counts a trust as 'live' when its data flows through the platform, even with no app in use.
How it works
Torbay's trust says it is not using the platform day to day.
Seen it before
A club that counts everyone who once bought a ticket as a member looks bigger than the crowd at games.
The truth
NHS England says nearly 140 trusts now report benefits, including back-office data work.
Why it works on people
A precise number, like 117,539 extra operations or a smaller wrinkle, feels like proof even when nobody has shown the cause.
Who gains
Palantir
Its NHS contract is defended partly with a benefits list that includes trusts not using its system.
Nobody knows yet
How many NHS trusts really use Palantir's platform for patient care.
NHS England says nearly 140 report benefits, counting back-office data work, and 29 on its list say they use none of its apps. The statistics watchdog is now looking at it.

Hospital admits a baby would have lived

A Newcastle hospital trust has admitted a baby would have survived had her mother not been sent home.
Danielle Brown
seven months pregnant; sent home
Royal Victoria Infirmary
Newcastle
Danielle Brown, 31, was seven months pregnant with pre-eclampsia when she was discharged in February 2023.
Pre-eclampsia is a pregnancy illness that can threaten the mother's life.
How it got here
First
told to stay until birth
24 hours later
sent home
One consultant said she should stay in hospital until the birth.
When she insisted on being seen, staff could not find a heartbeat.
“told to book a slot to give birth”
She was then given a booklet for bereaved parents and told to book a slot to give birth.
The trust paid an undisclosed settlement and apologised.
Why it matters
Irwin Mitchell, her law firm, says it acts for hundreds of families hurt by maternity failings in England.
How it works
Her lawyer says pre-eclampsia is serious and needs close monitoring.
Seen it before
A pan left on the stove needs someone watching, because it can boil over in a minute.
The truth
The trust says it was recently judged to be performing well against national standards.
Who pays
Danielle Brown and her family
Their daughter Maisie died, and the trust's admission came with a settlement more than two years later.

Spain adds paid leave for menopause
Swipe up for the story ↑Scroll down for the story ↓
Spain will give paid sick leave for disabling menopause symptoms from 1 December.
Who is involved
Elma Saiz, Spain's minister for social security, defended the change.
Going through the menopause is not enough.
The state benefit starts on day 2 of leave, not day 4 as with ordinary sick leave.
The benefit is 60% of the usual pay measure for 20 days, then 75%.
How it got here
In 2023, Spain gave paid leave for disabling period pain.
Why it matters
Germany, Italy, Greece, Portugal and Turkey have no special menopause leave.
How it works
Spain calls this a new labour right: a legal claim to paid time off for a health condition.
How it works
With a benefit from day 2, a short spell of symptoms costs a woman less than ordinary leave.
Seen it before
A school that excuses a pupil with a doctor's note still keeps their place in class.
The truth
Only symptoms a doctor judges disabling count, so milder ones bring no new right.
How it works
Money around birth keeps more newborns alive
How it works
Social epidemiology studies how money, housing and work shape illness, and a family's money runs shortest around a birth.
How it works · step 1 of 5
Income falls just as a birth makes costs rise
How it works · step 2 of 5
Families fall behind on rent, food and travel to check-ups
How it works · step 3 of 5
Stress, poor food and losing a home raise the risk of early, small births
How it works · step 4 of 5
Early and small babies are the most likely to die in their first weeks
How it works · step 5 of 5
Cash paid before the shortfall keeps those bills covered
The twist
A newborn's death can start months earlier with a bill a family could not pay. Paying the family before the birth can stop that chain.
The picture
Newborn deaths in Flint, in the first four weeks of life, before and after Rx Kids began paying families.
Seen the same day
The care exists, but 3.8 million adults on Medicaid could not afford a reliable way to reach it, so the gap was money for transport, not medicine.
Seen the same day
A benefit from day 2 removes the lost income that pushes women with disabling symptoms to keep working while ill.
Seen the same day
Health cover will depend on proving 80 hours of work a month, so a job, a website and a form decide who keeps seeing a doctor.
The catch
Cash helps where shortage is the cause; it cannot fix an illness money did not cause, and one city's early result may shrink as other places try it.
The whole
The doctor in Flint sees the baby, the landlord sees the rent, and the city sees its budget.
The whole
None of them sees the whole chain, and most of us sit somewhere along one like it.
Who gains
Women in Spain with disabling menopause symptoms
They can stop work for symptoms with less income lost than under ordinary sick leave.

A clinic for sudden menopause after cancer
Swipe up for the story ↑Scroll down for the story ↓
A Brighton hospital has opened a pilot clinic for breast cancer patients pushed into sudden menopause by treatment.
Doctors call it complex menopause: symptoms that start abruptly and hit harder.
Who is involved
Rachel Bowman
from Hove; treated for breast cancer
Rachel Bowman, from Hove, was 46 when her cancer treatment began four years ago.
After one injection to shut down her ovaries, she had 20 to 30 hot flushes a day.
Renske McFarlane

University Hospitals Sussex

Dr Renske McFarlane leads the clinic.
What comes next
University Hospitals Sussex plans to spread the service across Sussex.
Why it matters
McFarlane says the effects of treatment can last for years after cancer care ends.
How it works
Natural menopause happens as hormone levels fall slowly over several years.
How it works
Cancer treatments such as ovarian suppression cut those hormones at once.
Seen it before
Walking slowly into a cold sea feels very different from being thrown in.
Good news
A new clinic in Brighton now treats women thrown into sudden menopause by breast cancer treatment.

A robot and £1.95m for endometriosis
Swipe up for the story ↑Scroll down for the story ↓
Northern Ireland's health minister, Robbie Butler, was expected on Monday to announce £1.95m for endometriosis care.
Endometriosis is when tissue like the womb's lining grows elsewhere, often around the ovaries.
The money includes £700,000 for two specialist centres, at Belfast City and Altnagelvin hospitals.
A £2.4m surgical robot at Belfast City Hospital has done 130 operations since May.
How it got here
Women in Northern Ireland wait about 7 years, on average, for complex gynae surgery.
Who is involved
Age 14
pain begins
22 years on
referred
Colleen Crothers had period pain from 14 and waited 22 more years for a referral.
Why it matters
Delays mean some women need their womb removed, as Crothers did at 41, and cannot have children.
How it works
Surgeons use the robot because its wrists turn in tight spaces in the pelvis.
How it works
Complex cases need several specialists at once.
Seen it before
A bus lane keeps buses moving even when the rest of the road is jammed.
The truth
The £2.4m robot was paid for by charity donations.

A woman in Wales says a GP told her a growing breast lump might be 'medical anxiety'.
“too young”
Beth Jenkins was 40 and says she was told she was 'too young' for breast cancer.
It was lobular breast cancer, a 5cm tumour that had spread to three lymph nodes.
How it got here
A second GP at the practice said she should have been referred straight away.
She is now classed as having no evidence of disease and will be checked for 15 years.
Why it matters
UK breast screening starts at 50, so younger women depend on a GP to refer them.

US Medicaid work rules near their start
Swipe up for the story ↑Scroll down for the story ↓
From 1 January, many adults on Medicaid must work, volunteer or study 80 hours a month to keep it.
Medicaid is the US public health insurance for people on low incomes and with disabilities.
How it got here
Georgia's Pathways program, a model for the rule, has tied cover to work since 2023.
After three years it covers 20,606 people.
What comes next
Pathways ends this year unless renewed.
- 1joblessness that lets a county qualify8%
The law lets states excuse counties where joblessness reaches 8%, or 1.5 times the US rate if lower.
Using July figures, 95 counties would qualify.
Why it matters
Researchers estimate 60,000 more people in one California district could lose cover by 2034, partly because of the law.
How it works
A work requirement ties health cover to hours of work that people must prove.
How it works
Georgia's benefits website has a record of glitches, errors and slow processing.
Seen it before
A pupil who did the homework but lost the sheet still gets marked as not handing it in.
The truth
CMS, the US agency running the rule, has not said which jobless figures count or how long exemptions last.
How it works

The idea, in story 5: Money around birth keeps more newborns alive →Who pays
Georgia Pathways members such as Trey Wright
If the program ends in December, they lose cover; it saves Wright more than $1,700 a year on allergy shots.

Medicaid users in counties just under the jobless line
They must log 80 hours a month while people a county away may be excused.

Millions miss care for lack of a ride
Swipe up for the story ↑Scroll down for the story ↓
More than 3.8 million US adults on Medicaid missed care, work or daily needs for lack of reliable transport.
The count is from KFF, a US health research group, using a 2024 national health survey.
Medicaid must pay for rides to care, by van, bus, taxi or ride share, for people with no other way.
The rides cost less than 1% of Medicaid spending.
How it got here
In September, a US House committee report named the rides among services with 'high rates of fraud'.
What comes next
A bill would make every ride logged electronically, as home care visits already are.
Why it matters
Older people
use rides more
Disabled people
use rides more
People who use the rides are more likely to be older, disabled or living with long-term illness.
How it works
Health policy researchers weigh fraud checks against access.
How it works
Fewer ride firms means fewer trips for people who cannot drive themselves.
Seen it before
When a school cuts a bus route, pupils who live farthest away miss the most lessons.
The truth
KFF says some people who qualify for the rides may not know the benefit exists.
How it works
The care exists, but 3.8 million adults on Medicaid could not afford a reliable way to reach it, so the gap was money for transport, not medicine.
The idea, in story 5: Money around birth keeps more newborns alive →What's really going on
Across the rest of the day, money and paperwork decided who reached care.
Who pays
Older, disabled and chronically ill people on Medicaid

January
plan for DSM-6 set out
Its publisher, the American Psychiatric Association, set out the plan in January.
Who is involved
Anand Kumar, a Chicago psychiatrist who sat on the planning committee, explained it in an interview this week.
Today diagnoses rest on symptoms found by interview, case history, questionnaire or observation.
Apart from Alzheimer's, no blood test or scan can diagnose a mental disorder, Kumar says.
Why it matters
Diagnosis will stay based on symptoms, Kumar says, with biology added as background.
How it works
Psychiatric genetics finds hundreds of genes, each raising the risk of depression or anxiety by a small amount.
How it works
Many disorders share genes.
Seen it before
Height runs in families through hundreds of genes, with no single tall gene.
The truth
“reaching a bit”
Kumar has left the committee, and calls his own example of clinic use 'reaching a bit'.

A Dutch MP has proposed a law banning the most harmful addictive design in apps and websites.
Who is involved
Barbara Kathmann, of the opposition party PRO, filed it on 2 November.
It names endless scrolling, autoplay videos, push notifications and manipulative algorithms.
Platforms would have to prove their services are not addictive.

In August, Meta gave $15m to a similar project aiming for 15,000 hours of scans.
What comes next
Data collection starts early next year, says Russell Poldrack, a Stanford psychologist.
Why it matters
The goal is a model that predicts how a person responds to treatments such as magnetic brain stimulation.
How it works
A foundation model is an AI trained on a huge amount of data, then reused for other jobs.

Following each person over time also picked up deeper physical and mental exhaustion.
The study appeared in npj Digital Medicine on 3 November.

Why it matters. Current ways of measuring fatigue make it hard to follow how it builds in one person, the authors say.
The evidence on collagen pills

Collagen pills do not deliver collagen to the skin, a New Scientist look at the evidence finds.
Collagen is the main protein holding skin firm.
Digestion breaks supplement collagen into pieces of one to three amino acids, the same as from meat.
“a good steak”
A skin researcher says a supplement does no more than 'a good steak'.
Some trials report smaller wrinkles, but by only a fraction of a millimetre.
Why it matters
Exercise and sun protection have better evidence for keeping collagen, dermatologists told the writer.
How it works
Skin researchers found ageing skin still has the building blocks.
How it works
So adding more building blocks does not fix the slow assembly.
Seen it before
Buying more bricks does not speed up a builder who is working slowly.
The truth
In September, two researchers flagged 'substantial methodological concerns' in collagen studies.

US dentists report more patients asking about fluoride-free toothpaste made with hydroxyapatite.
Hydroxyapatite is a calcium phosphate mineral.
How it got here
Some of the interest seems to follow attacks on fluoride by Robert F Kennedy Jr, the US health secretary.
Two trials, of 177 children and 171 adults, found it about as good as fluoride at preventing decay.
Why it matters
The CDC, the US public health agency, says fluoride in water cuts tooth decay by 25%.
How it works
Dentists call it remineralisation when minerals move back into enamel.
How it works
Fluoride left in saliva after brushing brings calcium and phosphate back.
Seen it before
Filling small cracks in a path stops them growing into potholes.
The truth
Both trials were part-funded by Dr Wolff Group, a German firm selling hydroxyapatite toothpaste.

More than 6,500 people have lost weight in a government-backed obesity programme in Abu Dhabi.
People with obesity lost 14% of their body weight on average in the first year.
Patients chose weight-loss injections or, since May, pills.
Who is involved
Department of Health, Abu Dhabi
pays for and runs it
Abu Dhabi Public Health Centre
runs it
Abu Dhabi's health department and its public health centre run it.
What comes next
The drugs are offered at 54 health centres, with 15 more planned.
Why it matters
Losing 13% of body weight is linked to a 41% lower risk of type 2 diabetes, one study found.
How it works
“a complex chronic disease”
The programme's director calls obesity 'a complex chronic disease'.
How it works
Drugs such as Wegovy and Mounjaro curb appetite and dampen food cravings.
Seen it before
A lid on a sweet jar makes it much easier to walk past it.
The truth
The results are the programme's own figures, given by the health centre that runs it.

Waiting for an inspection keeps staff on edge
Swipe up for the story ↑Scroll down for the story ↓
A researcher studied university staff in the UK and Ireland who train teachers, while they waited for inspections.
Many described anticipatory stress: worry about an event that has not happened yet.
In England, every teacher-training provider is inspected by Ofsted, the education inspector.
“constant red alert”
Some said they lived on 'constant red alert' while waiting for the call.
“but I could get the call”
One said every family plan came with 'but I could get the call'.
Preparing for it could 'almost double' the workload, some said.
Who is involved
Sabrina Fitzsimons, the researcher, wrote up the work for The Conversation on 2 November.
Why it matters
Restructures, mergers and new AI tools now leave many workers in the same long wait, she writes.
How it works
Psychologists call it perseverative cognition: worry that keeps a stress alive when the event itself is absent.
How it works
When people cannot control the event or know how to prepare, the mind keeps working on it.
Seen it before
Waiting outside the head teacher's office can feel worse than the talk itself.
The truth
The findings come from interviews the researcher quotes, not from a count of how many staff feel this.

Office days without meeting anyone
Swipe up for the story ↑Scroll down for the story ↓
Nearly half of US office workers had no in-person meetings on their last office day, a survey finds.
The share was 48.8%.
It asked 1,835 college-educated workers in September.
37% had at least one video meeting with everyone in the same office.
70.6% had at least one teammate missing on their office days.
How it got here
1 of 4
US workers fully remote
About 1 in 4 US workers is now fully remote, US labour figures show.
Who is involved
Natalia Emanuel
New York Fed economist
Emma Harrington
University of Virginia economist
Economists Natalia Emanuel and Emma Harrington wrote the paper.
Why it matters
US time-use data show people spend more time physically alone on office days than before the pandemic.
How it works
“in-office remote work”
The authors call it 'in-office remote work'.
How it works
Teams are spread across offices, and some colleagues stay home.
Seen it before
Sitting in a full classroom with headphones on still leaves you working alone.
The truth
The survey does not count meetings with clients or people outside the team, the authors say.
