Age-related hearing loss impacts one in three adults aged 64 to 75 in the US, and around half of these cases are down to faulty genes. Using older animals to mirror a human study, scientists successfully reversed hearing loss caused by one such gene.

Chronic muscle loss doesn't simply make a person physically weaker. Among other things, it increases the risk of serious falls … and even death. A new urine test, however, could allow it to be detected earlier than ever before.
-
Scientists at UC San Diego have developed a way to potentially slow down the cellular aging process, using an oscillating genetic 'clock.' In tests, yeast cells were found to live significantly longer than those without.

Age-related macular degeneration is a debilitating eyesight loss, that robs nearly 20 million Americans of their independence. What if understanding this incurable condition and creating better therapies for it starts in the eyes of jumping spiders?

It's a natural part of aging, but nonetheless many of us would rather keep the color than see a head of hair fade to gray. Now, scientists have uncovered a key mechanism in stem cell movement and have the fix for age-related gray in their cross hairs
-
Research which shows why DNA is repaired in certain cells but not in others could help ward off the ravages of aging, and diseases including cancer. It all hinges on a protein group called the DREAM complex.

Could the enzyme that detoxifies and eliminates the harmful ethanol in alcohol from our bodies also be able to promote healthier, longer lifespans? Scientists have discovered a surprising mechanism that could provide this molecular fountain of youth.
-
In what sounds like sci-fi, transfusions of youthful blood can improve the health of older people. A new study has found that an existing arthritis drug can effectively rejuvenate blood stem cells, mimicking the benefits of young blood transfusions.
-
A study has looked at six key healthy lifestyle factors that can significantly reduce memory loss in old age, finding adults engaging in between four and six healthy behaviors could significantly reduce their risk of developing dementia.
-
Researchers studying healthy centenarians have homed in on a gene mutation that plays a crucial role in maintaining cardiovascular health in old age. Across a series of experiments the researchers demonstrated how gene therapy could rejuvenate aging hearts.
-
New research has found HRT can be linked with better brain health and cognition among women with a genetic risk of developing Alzheimer's. The findings build on research trying to understand why women are more likely to develop Alzheimer's compared to men.
-
Harvard scientists have investigated why we age, and how we could stop it. In tests in mice, the team showed that epigenetic “software glitches” drive the symptoms of aging – and a system reboot can reverse them, potentially extending lifespan.
