People don’t get rich by being selfless and generous. They get rich by being greedy and exploiting everybody they can. They just can’t understand how public healthcare works.

The end of cognitive decline? Researchers just used nanoparticles to reverse neurological damage caused by Parkinson's disease.

Parkinson's, a neurodegenerative disease affecting millions, involves the accumulation of alpha-synuclein protein in the brain, leading to dopamine neuron death and motor control loss.

The new approach uses gold nanoparticles coated with antibodies and peptides, designed to target specific neural receptors and break down harmful alpha-synuclein fibrils.

The treatment was successful on mice, and humans could be next.

Nanoparticles, guided by antibodies, are delivered to the brain and attach to damaged dopamine neurons. Near-infrared light, shone through the skull, activates the nanoparticles, converting light to heat. This heat triggers cellular repair and releases peptides that dissolve harmful protein tangles, restoring the neurons and improving motor function.

This differs from current treatments that boost dopamine levels with medication, often causing side effects.

The nanoparticle system targets the root cause, "reawakening" damaged neurons to produce dopamine naturally, eliminating the need for problematic drugs. While still in early stages, with tests only on mice and cell models, the results are promising. The treatment dramatically improved Parkinson's-like symptoms in mice without observed side effects. The wireless nature of the system allows for activation without further invasive procedures. While human trials are distant, this proof-of-concept study offers hope for a less invasive, more effective Parkinson's treatment.

Research shows a cat's purr can heal bones and promote tissue repair:

Cats may purr when snuggled in your lap, but the soothing rumble isn’t just a signal of happiness.

Research suggests that the vibration is produced by muscles within the larynx, which dilate and constrict the glottis as the cat breathes. This results in a sound with frequencies ranging from 20Hz to 150Hz — known to correspond with therapeutic healing frequencies for bones and tissues in humans. Studies find that bones respond to the pressure of a cat's purr by hardening.

In fact, cats often purr in stressful situations, during recovery, or even when facing death, hinting that the purr may function as a form of self-soothing or physical rejuvenation.

Behavioral experts, such as Marjan Debevere and Gary Weitzman, highlight the varied meanings behind a purr. Cats might purr to express nervousness, communicate with other cats, or simply as a way to encourage humans to feed them.

As researchers continue to study feline communication, one thing is clear: the purr is more than just a simple expression — it’s a biological marvel that deepens our understanding of the bond between cats and their humans.

Not my favourite time of day but it is beautiful. Thank you sun for keeping us alive. Now stop shining right in my eyes… 🤔🤷‍♂️🙄😏
