Medical Xpress / AI helps identify regulatory hub for aging in hematopoietic stem cells
Stem cells possess the unique ability to self-renew and transform into different types of cells. For example, rare hematopoietic stem cells found in bone marrow can become any type of blood cell. Throughout life, they can ...
Medical Xpress / Blocking cellular 'freecycling' may slow bone marrow scarring in myelofibrosis
In a new study published in Nature Communications, Boston Children's Hospital researchers identified a new target responsible for scar formation in the bone marrow of patients with a type of blood cancer known as myelofibrosis. ...
Phys.org / Listening for extinction: Study finds areas of critical concern for northern spotted owls
Northern spotted owl populations are approaching or have already crossed functional extinction across large areas of the Pacific Northwest, a new study, published in Ecological Applications found. Researchers used artificial ...
Phys.org / Oldest human brain cells grown in lab 'recorded passage of time'
Peppercorn-sized clumps of human brain cells grown in a lab for a record seven years aged similarly to those inside our heads, suggesting they "recorded the passage of time," scientists said Wednesday.
Phys.org / A little Big Bang: Bowling-pin-shaped nuclei shed new light on the universe's first moments
What happened in the first moments of the universe—before the building blocks of life and the world we know today came into existence? Physicists at the CERN research facility in Switzerland are trying to answer this question ...
Medical Xpress / MRI may help predict progression in early-onset Alzheimer's disease
Mass General Brigham Neuroscience Institute researchers have found that a pattern of brain atrophy visible on MRI could help predict how quickly people with early-onset Alzheimer's disease progress from mild cognitive impairment ...
Medical Xpress / Eminent cardiologist involved in treatment guidelines received £50 million from drug research contracts
A British cardiologist and former president of the European Society of Cardiology (ESC) has been judged by the ESC to have committed severe misconduct after a Danish TV documentary reported that he had been involved in drawing ...
Phys.org / Why marine heat waves and acidification strike together
Marine heat waves and extreme ocean acidification events are each damaging on their own. But when both stressors hit simultaneously, their individual effects can be exacerbated.
Phys.org / A tiny drop of water is all that's needed to find threatened frogs
New James Cook University research has used highly sensitive environmental DNA (e-DNA) techniques to find two species of threatened frogs in places they've never been seen before—and find another still struggling to recover ...
Medical Xpress / Early nicotine vapor exposure increases nicotine seeking later in life, study finds
Nicotine vaping during adolescence may leave a lasting imprint on the brain's reward system, driving nicotine-seeking behavior well into adulthood even after long stretches without any exposure, according to new research ...
Medical Xpress / A rogue neuronal signal may lie at the root of Alzheimer's disease
What if amyloid plaques are not the whole story of Alzheimer's disease? New research suggests that a broad range of Alzheimer's pathologies may be orchestrated by a molecular switch called ERBB4 when it turns on in the wrong ...
Phys.org / New workflow helps ecologists measure how individual animals use their habitat
A researcher has developed a new, reproducible workflow that lets ecologists measure, in a standardized way, how individual animals within a species differ in their habitat use, based on GPS tracking data. The tool was developed ...
