Stanford study reveals how ribosomes may contribute to age-related diseases

Aging leads to a decline in cellular fitness and loss of optimal protein function. Many age-related ailments, including Alzheimer's and Parkinson's diseases, are caused by protein aggregation, a result of errors in protein folding.

Intermittent fasting slows aging and increases longevity in fruit flies, study shows

Whether intermittent fasting is called the 5:2 diet or the 16/8 method, celebrities swear that these eating regimens are a great way to lose weight. Fasting is now trendy, but real science backs up claims that fasting two days a week or restricting eating to an eight-hour window each day leads to weight loss.

Study: Sous vide cooking increases the digestibility of beef protein

Once used to prepare cuisine in only the finest restaurants, sous vide is now making its way into home chefs' kitchens. French for "under vacuum," the technique involves vacuum sealing food in a plastic pouch and then slowly cooking it in warm water.

Vacuolar Tauopathy: New, rare genetic form of dementia discovered

A new, rare genetic form of dementia has been discovered by a team of Penn Medicine researchers. This discovery also sheds light on a new pathway that leads to protein build up in the brain -- which causes this newly discovered disease, as well as related neurodegenerative diseases like Alzheimer's Disease -- that could be targeted for new therapies. The study was published today in Science.

Researchers identify osmotic stress as stimulator of cellular waste disposal

Cellular waste disposal, where autophagy and lysosomes interact, performs elementary functions, such as degrading damaged protein molecules, which impair cellular function, and reintroducing the resulting building blocks such as amino acids into the metabolic system.

Protein modification may cause long-term consequences

Sometimes proteins misfold. When that happens in the human brain, the pileup of misfolded proteins can lead to neurodegenerative diseases like Alzheimer's, Parkinson's and ALS.
