By ScienceDaily - New findings reveal a subtle but powerful breakdown that may help explain early memory loss in Alzheimer’s. When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like mice, this replay...

By NewScientist - Gene-editing citrus fruits to make them less bitter could not only encourage more people to eat them, it might also help save the industry from a devastating plague If you never eat grapefruit because you find them far too bitter, CRISPR varieties...

By Suzanne Day - Harvard Medical School - The future of federally funded research at Harvard Medical School — supported by taxpayers and done in service to humanity — remains uncertain. Learn more. One of the most enduring goals in regenerative medicine is deceptively...

by Weizmann Institute of Science - MedicalXpress - What determines how long we live—and to what extent is our lifespan shaped by our genes? Surprisingly, for decades, scientists believed that the heritability of human lifespan was relatively low compared to other...

by Mariam Issimdar - BBC - A mother who donated umbilical cord blood after giving birth has described how her own daughter's life was saved by a similar donation just a few years later. Natasha Kirkpatrick donated her daughter Ellaria's cord blood when she was born in...

By HealthDay - US NEWS - The National Institutes of Health (NIH) said that it will stop funding all research that uses human fetal tissue, ending support for studies both inside and outside the agency. In a statement, the NIH said it will no longer fund “grants,...

By CNN News - The Trump administration announced Thursday that human fetal tissue derived from abortions can no longer be used in research funded by the National Institutes of Health. The policy, long urged by anti-abortion groups, expands restrictions issued during...

By University of Miami Miller School of Medicine - A pair of University of Miami Miller School of Medicine stroke experts are examining how stem cells interact with the immune system to protect and repair the brain after stroke. Dileep R. Yavagal, M.D., professor of...

By Science Daily - Researchers have found a reliable way to grow helper T cells from stem cells, solving a major challenge in immune-based cancer therapy. Helper T cells act as the immune system’s coordinators, helping other immune cells fight longer and harder. The...

By Carissa Wong - NewScientist - Cancer that spreads to bones can be deadly, and it also tends to be painful. Now, a drug seems to address both problems by disrupting the interplay between nerves and tumours, suggesting the approach could provide a more comfortable...

By Christina Elston - Cedars Sinai - Peggy Whitson, America’s Most Experienced Astronaut, Discusses the Next Generation of Off-Planet Science With Cedars-Sinai Space Medicine Research Expert Astronaut Peggy Whitson, PhD, has spent more time in space than any astronaut...

By Esra Öz - NewScientist - Immune cells are most commonly engineered to kill cancers, but now, scientists have shown the technique makes the gut lining of older mice resemble that of younger mice, raising hopes that the same approach could work in people As we age,...

By American Parkinson's Association - Two new therapies are entering the final stages of clinical trials before potential FDA approval. One is a novel dopamine-based therapy for motor symptom management, and the other is a stem cell therapy poised to replace the lost...

By Fidji Simo - Healthcare isn’t working for patients or doctors, but AI tools can help. At this time last year, I was hospitalized for a kidney stone and developed an infection. The resident in charge took a quick look at my chart and prescribed the usual antibiotic...

by Gaby Clark - MedicalXpress - A new study by Canadian and U.S. researchers is shedding light on how the social media platform TikTok can be used to recruit young stem cell donors. For the study, researchers shared an array of TikTok videos, all of which encouraged...

By Mental Health - Every year, millions of lives are suddenly, swiftly transformed by a stroke, which occurs when a blood vessel travelling towards the brain becomes obstructed, causing neurons to die off. Strokes are among the leading causes of disability in adults,...

By University of British Columbia - For the first time, researchers at UBC have demonstrated how to reliably produce an important type of human immune cell — known as helper T cells — from stem cells in a controlled laboratory setting. The findings, published today in...

By Bruce Goldman - Stanford Medicine - Stanford Medicine investigators have unearthed the biological process by which mRNA-based vaccines for COVID-19 can cause heart damage in some young men and adolescents — and they’ve shown a possible route to reducing its...

by University of New South Wales - Science Daily - A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act like molecular anchors. The work confirms these tags actively silence genes, settling a...
