Brain halves increase communication to compensate for aging, study finds

Increased communication between distant brain regions helps older adults compensate for the negative aspects of aging, reports a new study.

Why we did not evolve to live forever: Unveiling the mystery of why we age

Researchers have made a breakthrough in understanding the origin of the ageing process. They have identified that genes belonging to a process called autophagy -- one of the cells most critical survival processes -- promote health and fitness in young worms but drive the process of ageing later in life.

People with schizophrenia left out of longevity revolution

A team of researchers has analyzed all eight published longitudinal studies of mortality in schizophrenia that met their strict research criteria and found that the mean standardized mortality ratio -- a measure of the mortality rate in schizophrenia -- has increased 37 percent from pre-1970s studies to post-1970s studies.

Systems analysis points to links between Toxoplasma infection and common brain diseases

Nearly one out of every three humans on earth has a lifelong infection with the brain-dwelling parasite Toxoplasma gondii. In a new report, researchers from multiple institutions describe efforts to learn how infection with the parasite...Show More Summary

'Superbug' bacteria gang up on us, fueled by antibiotic use, nursing home study suggests

What's worse than getting exposed to a kind of bacteria that modern antibiotics can't kill? Getting exposed to more than one -- because they may work together to cause an infection, new research suggests. And trying different antibiotics to control one such 'superbug' may only encourage others. Show More Summary

Hip fracture often deadly, study shows

There is excess mortality risk from hip fracture while accounting for pre-injury comorbid conditions, shows a large population-based matched cohort study. The study found that hip fracture sufferers experienced significantly worse survival at 12-months post-fracture. Show More Summary

Human skin cells transformed directly into motor neurons

Scientists have converted skin cells from healthy adults directly into motor neurons without going through a stem cell state. The technique makes it possible to study motor neurons of the human central nervous system in the lab. Unlike...Show More Summary

Connection between low oxygen levels, human gene discovered

Researchers have established a link between hypoxia, a condition that reduces the flow of oxygen to tissues, and HOTAIR, a noncoding RNA or molecule that has been implicated in several types of cancer.

Biologists slow aging, extend lifespan of fruit flies

In research that potentially could delay the onset of Parkinson's disease, Alzheimer's disease, cancer, stroke, cardiovascular disease, and other diseases of aging, biologists have produced a genetic one-two punch that significantly slowed aging and improved health in the middle-aged fruit flies they studied.

Eat fat, live longer?

As more people live into their 80s and 90s, researchers have delved into the issues of health and quality of life during aging. A recent mouse study sheds light on those questions by demonstrating that a high fat, or ketogenic, diet not only increases longevity, but improves physical strength.

Intermittent electrical brain stimulation improves memory

Intermittent electrical stimulation of an area deep inside the brain that degenerates in Alzheimer's appears to improve working memory, scientists report. Conversely, continuous deep brain stimulation, like the type used for Parkinson's and currently under study in humans with Alzheimer's, impairs memory, according to study.

Protein that extends life of yeast cells

To understand and control aging is the aspiration of many scientists. Researchers have now discovered that the protein Gcn4 decreases protein synthesis and extends the life of yeast cells. Understanding how individual genes affect lifespan opens new ways to control the aging process and the occurrence of aging-related diseases.

Researchers review the clinical potential of senolytic drugs on aging

Researchers are moving closer to realizing the clinical potential of drugs that have previously been shown to support healthy aging in animals. Aging experts say that, if proven to be effective and safe in humans, these drugs could be 'transformative' by preventing or delaying chronic conditions as a group instead of one at a time.

Gold nanoparticles fry cancer on glowing mice

A new study takes a new approach to killing cancer: Why not fry it into oblivion with vibrating gold nanoparticles?

Tears in tiny bone cells called osteocytes appear an important step to better bones

The force gravity and physical activity put on our bones causes tiny tears in the membranes of the tiny cells that enable us to make or break down bone, scientists say. While that may sound bad, it's actually a key piece of how the force we put on our bones helps keep them strong, they report.

Brain's defense cells live longer than expected

In mice, microglia may persist the entire lifespan of the animal. The cells' lifetime may be linked to their role in immune memory and neurodegenerative diseases.

Relative risk of Alzheimer's between men and women: Record corrected

White women whose genetic makeup puts them at higher risk for Alzheimer's disease are more likely than white men to develop the disease during a critical 10-year span in their lives. The findings from one of the world's largest big-data...Show More Summary

Is telomere length associated with the cognitive response to a lifestyle intervention?: Supporting evidence from the FINGER trial

Is telomere length associated with the cognitive response to a lifestyle intervention? Supporting evidence has been provided by researchers

Physical activity in midlife not linked to cognitive fitness in later years, long-term study shows

A study that tracked activity levels of 646 adults over 30 years found that, contrary to previous research, exercise in mid-life was not linked to cognitive fitness in later years.
