Is sweeping enough to reduce slip and fall incidents?

Dry contaminants like salt, dust, or flour can be as hazardous as spills. Our study shows #DryParticles lowers #SlipResistance by 19%.

Slower arm movements linked to greater fall risk for older adults

A first-of-its-kind study could inform physical therapy protocols aimed at strengthening arms to prevent falls likely to cause hip fractures.

Explosive arm movements help a person who is slipping regain balance and prevent a potentially catastrophic fall.

Older adults have slower arm acceleration that may make stabilization during falls more difficult.

New research could lead to more effective physical therapy protocols to prevent potentially devastating falls in older adults.

🧠💥 When you slip, your arms whip out like a tail to save you — but older adults react 36% slower, causing nearly twice the sideways shift, making balance recovery harder.
New study suggests faster arm reactions may be key to better fall prevention. #Aging #balance #exercise

[New Scientist @newscientist]

Older people may be prone to falls because they move their arms more slowly than their younger counterparts when they slip, with this helping us to regain our balance https://t.co/ELVsCUestU

I didn`t start my academic career until I was 30.
I didn`t obtain my PhD until I was 35.
At 20, I thought my life was over🎗️
At 42, I know it`s just the beginning & I signed the contract for my permanent position (tenure track/ assistant professor).
It is never too late to start.

Decoding Cognitive Decline: Key Aging Mechanism Discovered

Researchers have discovered that the mis-regulation of the brain protein CaMKII is a key mechanism behind cognitive decline during normal aging. This opens the door for new drug development strategies to fight age-related memory loss.
