1. Scientists discover hormone that may stop chronic back pain at its source

   A new study suggests a widely used bone hormone could help relieve chronic back pain in an unexpected way. Instead of just strengthening bone, it appears to stop pain-sensing nerves from growing into damaged spinal areas. In animal models, this led to stronger spinal tissue and reduced pain sensitivity. The findings hint at a future treatment that tackles back pain at its biological roots.

2. A hidden brain problem may be an early warning for Alzheimer’s

   Researchers discovered that clogged brain “drains” show up early in people at risk of Alzheimer’s disease. These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some cases, they may signal Alzheimer’s earlier than other commonly used brain markers. This could help physicians detect the disease earlier, before irreversible damage sets in.

3. Scientists discover why mental disorders so often overlap

   A massive global genetics study is reshaping how we understand mental illness—and why diagnoses so often pile up. By analyzing genetic data from more than six million people, researchers uncovered deep genetic connections across 14 psychiatric conditions, showing that many disorders share common biological roots. Instead of existing in isolation, these conditions fall into five overlapping families, helping explain why depression, anxiety, PTSD, bipolar disorder, schizophrenia, and substance use disorders so frequently occur together.

4. Parkinson’s reversal? One drug brings dying brain cells back to life

   Stanford researchers discovered that dialing down an overactive enzyme, LRRK2, can regrow lost cellular “antennae” in key brain cells, restoring vital dopamine communication and neuroprotective signals in a mouse model of genetic Parkinson’s. After three months on the LRRK2-blocking drug MLi-2, damaged circuits revived and early signs of neuronal recovery emerged, hinting that timely treatment could not only halt but reverse disease progression—and perhaps benefit other Parkinson’s forms.

5. How thyroid hormone fuels the drive to explore

   Research in mice sheds light on how thyroid hormone alters wiring in the brain. Findings reveal that thyroid hormone syncs up the brain and body to drive exploratory behavior. Researchers say their work could illuminate new treatments for certain psychiatric conditions.

6. Keeping skin healthy: New method provides molecular portrait of sebum production

   Changes in gene expression in sebaceous glands have now been spatially mapped. The study documents at high resolution changes in gene expression in the course of sebum synthesis and identifies new candidates for the modulation of sebum production.

7. Bipolar disorder linked to early death

   Having bipolar disorder -- a serious mental illness that can cause both manic and depressed moods -- can make life more challenging. It also comes with a higher risk of dying early. Now, a study puts into perspective just how large that risk is, and how it compares with other factors that can shorten life.

8. Enlarged spaces in infant brains linked to higher risk of autism, sleep problems

   Researchers have found that enlarged perivascular spaces in the brains of babies, caused by an accumulation of excess cerebrospinal fluid, have a 2.2 times greater chance of developing autism later in life.
