The Roots of Dementia Trace Back All The Way to Childhood, Experts Reveal - ScienceAlert

Deleting a conversation with an artificial intelligence (AI) assistant may not erase everything the assistant remembers. Georgia Tech researchers have developed a tool that can recover deleted conversations from AI assistants running on Android phones. The tool, called ORISA, can also rebuild the recovered information into a working AI session.

A facial mass detected before birth prompted the early delivery of identical twin sisters. A fetal MRI at 33 weeks showed the mass on one baby's face. When the sisters were born a week later, tumors were found in both. Two children had the same cancer, raising a question that their shared beginnings alone could not answer. Had the disease started separately in each sister, or had cancer cells crossed from one to the other before birth? Researchers turned to a record hidden within their cells. DNA changes, accumulated as their bodies developed, allowed the team to reconstruct events that had happened months before anyone saw a tumor. The study in Nature Communications shows that the cancer began in one sister and passed to the other in the womb, most likely through a single transfer late in the second trimester. The same investigation uncovered clues to how the sisters themselves had formed. The two girls, Amelia and Amaya, died soon after birth. Their family consented to post-mortem examinations for research. The authors dedicate the study to the sisters, whose mother wanted them acknowledged by name.

Broaden observation dimensions to unlock untapped research insights with flexible multiple factors protein detection solutions HUSTON, TX, UNITED STATES, October 19, 2026 /EINPresswire.com/ -- Many researchers across universities, affiliated hospitals and research institutes are grappling with a shared challenge: difficulty sourcing original research topics, generating novel ideas and publishing high-quality papers. Even well-resourced laboratories with sufficient funding, complete experimental platforms and solid team capacity frequently hit a bottleneck in exploratory work. This article unpacks the root causes behind this widespread research dilemma and introduces an enabling tool to help researchers capture unexpected, high-value experimental signals during early-stage exploration. Many researchers in universities, affiliated hospitals and research institutes have recently encountered a common predicament: research topic shortage. This “topic shortage” does not stem from insufficient research funding, lack of experimental platforms or understaffed research groups.

Owners who spent more time physically close to their cats tended to report more positive moods, according to a new study by a Kyoto University-led team. The study, published in the journal iScience, came amid a common claim that caring for a feline friend has positive effects on human health and well-being while other studies reporting possible negative effects of cat ownership.
