The finding could reshape how doctors evaluate rare neurological emergencies and highlights the need for faster genetic testing in acute care settings.EN

Researchers modeled how marine plants responded to high CO2 levels 15 million years ago, finding that warming oceans could actually boost overall carbon fixation—but with major shifts in which species thrive. The findings help resolve a critical uncertainty for policymakers betting on ocean-based carbon removal and companies planning aquaculture and fisheries investments.EN

Scientists have identified the genetic networks underlying Stickler syndrome, a rare inherited connective tissue disorder that causes blindness, deafness, and joint damage. The mapping could accelerate development of targeted therapies and diagnostic tests for a condition that currently has limited treatment options.EN

Researchers have released MiMiCPy-FM, software that dramatically accelerates computational simulations of how drugs interact with proteins and enzymes. The tool cuts the time needed to model complex biological systems, potentially reducing development timelines and costs for pharmaceutical companies and biotech firms working on enzyme engineering and drug design.EN

Researchers identified a previously unknown mechanism where the brain simultaneously adjusts two separate chemical thresholds to lock in new memories while preventing forgetting. The finding could reshape how neuroscientists understand learning disorders and inform drug development for cognitive diseases ranging from Parkinson's to Alzheimer's.EN

Researchers have identified a way to restore leukemia cell sensitivity to cytarabine, a standard cancer drug that many patients' tumors resist. By pairing cytarabine with existing medications that block a different metabolic pathway, the study suggests a near-term path to improving outcomes for acute myeloid leukemia patients without developing entirely new drugs.EN

Researchers identified a group of overlooked RNA molecules that accumulate abnormally in myelodysplastic neoplasms and signal which patients will progress to leukemia within three years. The discovery could transform how doctors stratify treatment risk and develop new therapies for these difficult-to-treat blood cancers affecting tens of thousands annually.EN

Researchers have developed a systematic framework for cataloging genetic, behavioral, and physiological differences within populations of a single species—work previously impossible at scale. The approach, demonstrated in chimpanzees, could transform conservation strategy and help organizations prioritize protection efforts by revealing which populations hold the most genetic or ecological value.EN

Researchers used deep learning to identify over 2,000 previously unknown proteins that bind to RNA structures called G-quadruplexes, revealing a major gap in how cells manage stress. The discovery could accelerate drug development for cancer and neurological diseases, where these proteins play a central role.EN

Researchers developed a dual-function blood test that identifies early-stage breast cancer patients who face low recurrence risk and don't need radiation therapy after surgery. The test could spare thousands of women from unnecessary treatment side effects while accurately flagging high-risk patients who do need it—reshaping treatment economics and clinical decision-making for one of oncology's most common diagnoses.EN

Researchers have mapped out how to isolate, modify, and deploy naturally occurring particles found in milk as carriers for therapeutic drugs. The discovery could accelerate development of safer, cheaper treatments for cancer and neurological diseases by leveraging a renewable, biocompatible delivery system already produced at scale in dairy operations.EN

Scientists have mapped exactly how carcinogens in tobacco smoke damage DNA based on its packaging inside cells—and found these patterns match mutations seen in actual lung cancers. The discovery could help develop better screening tools and explain why certain smokers develop cancer while others don't.EN

A new study reveals that brain tumors and surgical bone flaps significantly distort electrical brain signals measured by EEG—a test relied on by hospitals and clinics worldwide. The findings could force healthcare providers to recalibrate how they interpret EEG data for millions of post-surgical and cancer patients, potentially affecting diagnostic accuracy and treatment decisions.EN

Researchers found that standard physiotherapy assessments—like standing on one leg or walking—are more sensitive than current procedures at predicting which elderly patients will benefit from shunt surgery for normal pressure hydrocephalus. The discovery could improve patient selection for a $50,000+ procedure and reduce unnecessary surgeries in this growing population.EN

Researchers identified a genetic variant in estrogen receptor-positive breast tumors that signals poor survival despite current hormone therapies. The finding could help oncologists identify high-risk patients earlier and guide decisions on more aggressive treatment strategies for this common breast cancer subtype.EN

A new study shows that COVID-19 restrictions on social, physical, and intellectual activities caused measurable declines in memory precision among older adults. The finding has implications for long-term care policy and workplace flexibility, suggesting that lifestyle constraints—even temporary ones—can accelerate cognitive aging in vulnerable populations.EN

Researchers discovered that cancer cells deliberately suppress a mitochondrial protein (ETFDH) that normally powers energy production, paradoxically making tumors grow faster. The finding could explain why this protein is switched off across many human cancers and opens a new therapeutic target for blocking cancer's energy optimization.EN

Researchers identified genetic variants associated with chronic pain conditions that also increase suicide mortality risk, suggesting a shared biological pathway. The finding could reshape how clinicians assess suicide risk and opens new targets for intervention in high-risk populations.EN

Scientists identified specific enzyme patterns in breast tumors that could help predict which patients benefit from antibody-drug conjugates, a class of precision cancer therapies. The findings, based on analysis of 66 patient samples, reveal how tumor composition influences drug effectiveness—information that could guide treatment selection and improve outcomes.EN

Researchers have identified a previously unknown regulatory mechanism in bacterial RNA structures—dynamic molecular switches that toggle between active and inactive states. The discovery, validated in E. coli, suggests a new class of drug targets and could reshape how companies develop antibiotics and RNA-based therapeutics.EN

Researchers found that ultra-soft polymer particles behave as unpredictable glass formers—their relaxation happens far faster than theory predicts. The discovery of a 'time-length scale superposition principle' could help manufacturers design better soft materials for cosmetics, pharmaceuticals, and industrial coatings by enabling more accurate modeling of how these substances flow and set.EN

Researchers have identified a significant drug-drug interaction between itraconazole, a common antifungal, and vepdegestrant, an experimental estrogen receptor degrader in development. The finding could affect dosing protocols and patient safety monitoring as the cancer drug advances through clinical trials and toward potential regulatory approval.EN

Researchers identified 14 patients with mutations in the RNU2-2 gene that triggers severe developmental epilepsy, intellectual disability, and seizures in infancy. The discovery could unlock new diagnostic pathways for hundreds of families with undiagnosed genetic epilepsies and guide development of targeted therapies for a previously unknown disease category.EN

Researchers respond to criticism of their nationwide finding that children born with orofacial clefts perform as well academically as peers without the condition. The response matters to healthcare systems and insurers evaluating treatment priorities and to families facing decisions about cleft repair timing and intensity.EN

A real-world study of nearly 400 ulcerative colitis patients shows infliximab works faster and better for severe cases, but adalimumab achieves identical remission rates over time. The finding could reshape treatment guidelines and reimbursement decisions, as adalimumab's lower cost and easier administration make it an increasingly attractive first-line option for milder disease.EN
