Hearing analysis reveals differences in perception of speech-like noises among younger versus older people. A new study suggests that people in different age groups use two distinctive techniques to filter out noise and focus on auditory signals resembling human speech. When younger people listen to these sounds, their brains naturally synchronize to the rhythm, and […]

Could those genes be making you look old?
A gene may be partially responsible for how old you look, according to a new study. The gene, MC1R, is known for producing red hair and pale skin, as well as playing a role in repair to damaged DNA and other biological processes. Researchers found people carrying the gene typically look almost two years older […]
Rejuvenating old bones
A molecule secreted from young blood cells can speed up fracture healing in elderly mice, reports a new Canadian study. Researchers showed that a specific molecule, either a chemical or a small protein,which is only secreted from young blood cells increased the regenerative capacity of bone cells. The study could help explain why fractures take […]
Healthy life, healthy mind
Healthy eating, exercising, and brain-training may be able to slow down cognitive decline in at risk individuals according to a new study. Researchers performed a randomised control trial of 1,260 people between 60 and 77 years old who were considered at risk for dementia. Individuals in the control group were given only regular health advice, […]
A solution to the medical isotope shortage?
Radioactive isotopes are used regularly for diagnostic and cancer treatments, but as aging nuclear research reactors are shut down, new ways to create the technetium 99m necessary for medical scans are being investigated. A team of scientists has now confirmed that regular hospital based cyclotrons are able to produce enough technetium-99m, to satisfy the daily […]
Exercise associated with fewer depressive symptoms
Regular exercise is associated with a reduction in the odds of depressive symptoms by up to 19 per cent, according to estimates in a new study. Researchers used data from the 1958 British Birth Cohort, which tracked about 11,000 people in the UK who were all born in the same week in 1958 through their lives. […]
A healthy mind with a healthy heart
A new study confirms that exercise and healthy lifestyle maintains the elasticity of the arteries and is linked to preserved cognitive abilities later in life. Researchers performed MRI scans and physical tests on 31 young people (aged 18-30) and 54 older participants (aged 55-75) and while they found that age-related decline of cognitive functions and […]
Seniors still at risk of stroke 2 years after heart surgery
Older people who have undergone surgery are at increased risk of suffering a stroke for up to 2 years afterward, a new study shows. While it was known that the risk increases immediately after surgery, the new study shows that the risk period extends longer than expected. Researchers followed 108,711 patients who had cardiac surgery […]
Kidney Donation is safe for older adults
Healthy kidney donors aged 55 years and older enjoy similar longevity and cardiovascular health than similar non-donor adults, a new study shows. The authors matched 3368 American donors to older healthy non-donors and followed them for nearly 8 years between 1996 to 2006 and found out that that donors were not at a higher risk […]
Launch of a “thermometer for the mind”
A free online brain health test developed by the memory experts at Baycrest Health Sciences can help those aged 50 to 79 assess changes in their memory and determine whether they need to see a doctor. The developers caution that the 20-minute test does not provide a clinical diagnosis, but say it can be a […]
Most NHL players peak by age 29
Hockey players reach their peak performance by age 29, according to a new mathematical analysis. The study used regular-season NHL records from 1997 to 2012 and compared player age with points scored per game. The authors estimate scoring peak age is slightly earlier by about a year for forwards (between 27 and 28) than […]
Empowered seniors make better medication choices
A randomized, controlled trial of 303 seniors from Quebec found that a simple intervention resulted in 27% of them becoming sleeping-pill free. The study emphasizes the importance of seniors being active and able participants in decisions about their health care. The researchers used a handout describing the risks of sleeping pill use and encouraging the […]
StarCraft 2 players get old at 24
As we age, our ability to process information and react in fast manner becomes dulled. New research shows that within a popular video game, StarCraft 2, response times start to decline at 24 years of age, regardless of a player’s skill. The authors analyzed data on 3,305 players aged between 16 and 44 of all […]
