Injecting senescent cells into young mice results in a loss of health and function but treating the mice with a combination of two existing drugs cleared the senescent cells from tissues and restored physical function. The drugs also extended both life span and health...

Scientists have discovered a 'Big Bang' of Alzheimer's disease -- the precise point at which a healthy protein becomes toxic but has not yet formed deadly tangles in the brain. read the full article

When a cell divides, its constituents are usually evenly distributed among the daughter cells. Researchers have now identified an enzyme that guarantees that cell constituents that are concentrated in organelles without a membrane are properly distributed. Their...

A new commentary on a study by epidemiologists supports the viability of a potential way to reduce the risk of Alzheimer's disease. When the authors looked at subjects who suffered severe herpes infection and who were treated aggressively with antiviral drugs, the...

Alzheimer's disease is a progressive, neurodegenerative condition that often begins with mild cognitive impairment (MCI), making early and repeated assessments of cognitive change crucial to diagnosis and treatment. Researchers have now found that repeated testing of...

Supplementing a single protein found in the spinal cord could help prevent symptoms of Lou Gehrig's disease, according to a new study. Researchers found high levels of the protein -- called mitofusion 2 or Mfn2 -- prevented nerve degeneration, muscle atrophy, and...

In an unexpected discovery, researchers have found that a gene previously known to control human metabolism also controls the equilibrium of bone and fat in bone marrow as well as how an adult stem cell expresses its final cell type. The findings could lead to a...

Scientists found that short-sleeping fruit fly mutants shared the common defect of sensitivity to acute oxidative stress, and thus that sleep supports antioxidant processes. read the full article

Researchers document the health problems that precede a diagnosis of multiple sclerosis. read the full article

Aging is a process of gradual deterioration from exposure to time and the elements; this process begins with deterioration deep inside every cell. Researchers have identified a protein that guards cells against senescence -- aging-related problems -- by protecting a...
