Medroxyprogesterone injections showed the highest meningioma risk in a 3 million-woman analysis, while lower-dose hormonal IUDs did not; the increase faded after stopping in most cases. @jamanetworkopen https://t.co/y1hWf4WzmW

Protection across three Parkinson’s models points to 15-PGDH inhibition as a potential way to slow neurodegeneration, even though one model’s α-synuclein buildup did not change @UHhospitals https://t.co/Yg2o6jxKUW

695 confirmed cases and 138 deaths mark the biggest Bundibugyo outbreak yet, exposing how delayed lab testing can slow isolation and contact tracing. @nejm https://t.co/ccCfLkG5IB

Nine gut bacteria were tied to future type 2 diabetes risk up to five years before diagnosis, including an unexpected pattern in Akkermansia muciniphila that may depend on fiber intake. @CellRepMed https://t.co/fa1Z7I0e8O

More than 80% of genome-edited T cells stayed viable, and 3 million starting cells yielded an average 72 million tumor-targeting cells using Platinum TALEN—though long-term survival in vivo still needs testing @Hiroshima_Univ https://t.co/fUbfv3s3Nj

Higher ultra-processed food intake tracked with 22 blood metabolites and 8 fatty acids, including a pattern tied to impaired fat processing that may help explain its health links. https://t.co/v5EM0Vo7GW

44% of vaccinated primates produced broadly neutralizing HIV antibodies, the first high-rate response of its kind, after a prime-and-boost regimen designed to steer naive B cells. @ljiresearch @natimmunol @nature https://t.co/TqGkO2uJLa

Statin muscle pain may stem from a separate immune response, not cholesterol lowering, and blocking that response prevented much of the damage in muscle cells and mice. @mcmastereng @ScienceAdvances https://t.co/Dsb7xC0aQX

Across 182 species, bigger limbic systems consistently came with smaller neocortices, pointing to an evolutionary trade-off in brain wiring rather than a battle between “logical” and “lizard” brains. @georgiatech @ScienceAdvances https://t.co/QlgJjkDuif

Four injections over six weeks sharply improved a rare autoimmune neuropathy in two patients, with pathogenic IgM antibodies no longer detectable after a short time. @NatureComms https://t.co/o0qBhtsAuQ

Memory showed the clearest gain in a 133-study review, where video games were linked to small overall cognitive advantages while long-term effects remained unclear. https://t.co/ixPChNcxua

Killer T cells were still present in breast tissue 10 years after pregnancy, a long-lived immune shift that may help explain childbirth’s protection against breast cancer. @petermaccc @natimmunol https://t.co/zlkfEr1s0s

Dream-like imagery appeared even during full wakefulness, while deliberate thoughts persisted into stage N2 sleep, suggesting the line between thinking and dreaming is far less fixed than it seems. @ConversationEDU @CellReports https://t.co/N2HKESqnQs

A 478-patient tumor map identified a high-risk B-cell lymphoma group standard therapy is unlikely to cure, marked by MYC-driven growth and an immunologically “cold” tumor environment. @goetheuni https://t.co/YbrOQqm9FA

Across 115 trials, yoga and omega-3 supplements reduced depression symptoms in pregnancy about as much as talking therapies, though the evidence varied across studies. @kingscollegelon https://t.co/XMaJ39mHcd

Speaking four languages was linked to brains that appeared about 13 years younger, with a stepwise pattern from two and three languages and an added role for early learning and fluency. https://t.co/uFZ7G8Lvqi
