New Drug Aims to Block Pain Without Addiction Risks

Chronic pain affects millions, but opioid medications bring high risks of dependence and side effects. Researchers have now pinpointed specific neurons in the amygdala that make pain feel unpleasant, opening the door to drugs that ease suffering without shutting down normal sensation.

Blocking Protein Reverses Age-Related Memory Loss

Aging disrupts memory by increasing levels of the protein FTL1 in the hippocampus, new research shows. In mice, excess FTL1 caused neurons to grow abnormally and led to memory decline, while reducing FTL1 reversed these impairments.

Genetics Explains Why Some Neurons Resist ALS

A new study has uncovered why some motor neurons resist degeneration in ALS while others succumb. Researchers found that neurons controlling eye muscles maintain high levels of protective genes like En1 and Galanin, shielding them from damage.

Radio Waves Can Strengthen Sense of Smell

A new study introduces a safe, painless way to improve the sense of smell using radio waves. Unlike traditional treatments that rely on strong scents or medications, this noninvasive method stimulates olfactory nerves directly through a small antenna placed near the forehead.

Enzyme Repairs DNA to Prevent Brain Disorders

A new study shows that the DNA repair enzyme Polβ plays a vital role in protecting the developing brain from harmful mutations. Researchers found that without Polβ, insertion-deletion mutations near CpG sites rose sharply, threatening genetic stability during crucial stages of brain growth.

Immune Attack on Smell Pathways May Signal Early Alzheimer’s

A fading sense of smell may be one of the earliest warning signs of Alzheimer’s disease, and new research reveals why. Scientists found that microglia, immune cells in the brain, mistakenly remove nerve fibers connecting the locus coeruleus and olfactory bulb—two regions essential for processing odors.

Bacteria and Viruses Join Forces in New Cancer-Killing Therapy

Researchers have developed CAPPSID, a novel cancer therapy that teams bacteria and viruses to infiltrate and destroy tumors. The system hides an oncolytic virus inside Salmonella typhimurium, which naturally migrates into tumors, shielding the virus from immune detection.

Could Restoring Lithium Levels Help Prevent Alzheimer’s Disease?

A decade-long investigation has revealed that natural lithium in the brain helps shield against Alzheimer’s disease by maintaining healthy function across all major brain cell types. Researchers found that lithium loss is one of the earliest brain changes in Alzheimer’s, often occurring before noticeable symptoms.

Neuron Discovery Could Help Restore Breathing After Spinal Injuries

Scientists have discovered a specialized group of spinal cord interneurons that help regulate breathing when the body faces challenges like high carbon dioxide levels. Blocking these neurons impaired the body’s ability to adapt its breathing, suggesting they play a key role in respiratory control.

Feline Dementia Mirrors Human Alzheimer’s

A new study shows that cats with dementia exhibit brain changes strikingly similar to those seen in Alzheimer’s disease, including the toxic build-up of amyloid-beta in synapses. These changes disrupt connections between brain cells and contribute to memory and thinking decline.

When Gut Rhythms Over-Sync With the Brain, Mental Strain Rises

A large-scale study has found that unusually strong coordination between brain activity and the stomach’s slow, rhythmic waves may signal greater mental distress. Using fMRI and electrogastrography on more than 240 people, researchers observed that higher synchronization was associated with elevated anxiety, depression, and stress.

Why the Blood-Brain Barrier Weakens With Age

A new study has uncovered why the blood-brain barrier — the brain’s protective shield — becomes leakier with age, potentially triggering memory decline. Researchers identified that proteins N-cadherin and occludin, which help maintain the barrier’s tight junctions, decrease over time.
