France becomes world’s first country to enshrine abortion rights in constitution

By / / Good News For Humankind

Constitutional abortion rights became reality in France on Monday when lawmakers gathered at Versailles voted 780 to 72 to embed the protection in the nation’s founding document — the first country anywhere to do so. The amendment guarantees a “freedom” to abortion, language Prime Minister Gabriel Attal framed as a moral debt owed to generations of women, and a message that “your body belongs to you.” That night, the Eiffel Tower glowed with the words “my body my choice.” The move came as a direct response to the unraveling of Roe v. Wade, and it offers the world a powerful new template: lifting reproductive freedom above the reach of shifting politics, where it becomes structurally harder to take away.

79% of Crohn’s disease patients in remission after early intervention

By / / Good News For Humankind

Crohn’s disease patients given the drug infliximab right after diagnosis reached sustained remission at a rate of 79% after one year, compared to just 15% for those on the standard step-by-step approach. The Cambridge-led trial of 386 patients also found that only one person in the early-treatment group needed urgent bowel surgery, versus ten in the conventional group. Researchers say the old wisdom of saving the strongest drugs for last lets quiet damage build up while the clock ticks. With cheaper biosimilar versions now widely available, this finding could reshape care for the millions living with Crohn’s worldwide — and it’s a powerful reminder that sometimes the best medicine is simply not waiting.

Dentist's Hand Taking Saliva Test From Woman's Mouth, for article on handheld saliva test for breast cancer

Hand-held test for breast cancer uses your saliva and gives accurate readings in 5 seconds

By / / Good News For Humankind

A handheld breast cancer screener developed by researchers in the U.S. and Taiwan can detect cancer biomarkers from a single drop of saliva in under five seconds — using a reusable circuit board that costs just $5 and paper test strips priced in pennies. Built on the same glucose-strip technology found in home diabetes kits, the device was designed specifically for clinics and communities where mammograms and MRIs aren’t an option. Lead author Hsiao-Hsuan Wan said the goal was to make screening possible where it simply hasn’t been before. Clinical trials and approvals still lie ahead, but if it gets there, early detection — one of medicine’s most powerful tools against breast cancer — could finally reach the millions of women long left out.

New drug quadruples three-year survival rates for mesothelioma in international trial

By / / Good News For Humankind

Mesothelioma survival rates have quadrupled over three years thanks to a drug that starves tumors of a key nutrient, marking the first successful new treatment combination for the disease in 20 years. The international ATOMIC-meso trial, led by Queen Mary University of London and published in JAMA Oncology, found that patients receiving pegargiminase alongside standard chemotherapy were significantly more likely to be alive three years later. The drug works by depleting arginine in the bloodstream, cutting off a nutrient that mesothelioma cells cannot produce themselves. For a cancer caused by asbestos exposure that has historically offered patients months rather than years, this breakthrough represents a genuine turning point.

Novel AI model rapidly determines if an antidepressant will work

By / / Good news links

Amsterdam University Medical Center (UMC) and Radboud UMC researchers have developed an algorithm that, based on patient MRI scans and other data, can determine within a week if a particular antidepressant will, offering faster relief and minimizing often painful and damaging side effects. “This is important news for patients,” said Liesbeth Reneman, Professor of Neuroradiology at Amsterdam UMC. “Normally, it takes six to eight weeks before it is known whether an antidepressant will work.”

Germany launches large four-day workweek trial

By / / Good news links

In February, 45 companies and organizations in Europe’s largest economy will introduce a 4-day workweek for half a year. Employees will continue to receive their full salary. Advocates argue that a 4-day workweek would increase worker productivity and, by consequence, help alleviate the country’s skilled labor shortage.

Chromosomes, for article on CRISPR gene therapy hereditary angioedema

Gene therapy hailed as ‘medical magic wand’ for hereditary swelling disorder

By / / Good News For Humankind

CRISPR gene editing has freed ten patients with hereditary angioedema from the sudden, sometimes life-threatening swelling attacks that shaped their daily lives, with several remaining attack-free for 18 months and counting after a single infusion. The therapy works by switching off a gene in liver cells, stopping the painful chain reaction at its source rather than just managing symptoms. One participant who used to have attacks every three weeks has needed no medication since. Doctors are now recruiting for a phase-three trial, building on the same Nobel-winning technology that recently produced an approved cure for sickle cell disease. For a rare condition long defined by unpredictability and fear, it’s a glimpse of what gene editing could mean for millions living with inherited illness worldwide.

Miami commits to putting 100 electric school buses on the road

By / / Good News For Humankind

Electric school buses are about to transform the daily commute for Miami-Dade students, with the district rolling out 100 of them thanks to a $19.1 million EPA grant, a Volkswagen award, and the school system’s own early investment. That makes it one of the largest electric school bus fleets in the country. The shift means cleaner air for kids waiting at the curb and quieter rides for the drivers behind the wheel, with no tailpipe emissions along the route. Miami-Dade’s blended funding approach — district dollars, federal support, and a corporate settlement — offers a model other communities can follow as the movement to electrify America’s roughly 480,000 school buses gathers speed.

Breakthrough Alzheimer’s blood test could detect disease 15 years before symptoms emerge

By / / Good News For Humankind

A simple Alzheimer’s blood test trialed in Sweden can detect the disease’s biological signs up to 15 years before symptoms appear, matching the accuracy of a spinal tap in a study of 786 people. The test measures p-tau217, a protein that builds up in the blood as Alzheimer’s-related changes unfold in the brain. Researchers suggest it could one day be as routine as a cholesterol check for anyone over 50, replacing painful lumbar punctures and hard-to-access specialist scans. With one in three people born in the U.K. today expected to develop dementia, catching the disease early — while there’s still time to intervene — could transform how the world confronts one of its most feared illnesses.
