Eye and heart complications are tightly linked in type 1 diabetes

In people with type 1 diabetes, high levels of blood glucose eventually can harm blood vessels in the eye, kidney, heart and other organs -- but the damage may be inflicted by different biological mechanisms in different organs. Scientists now have shown that similar mechanisms may also be at work in the eye and the heart, giving valuable clues that eventually aid in developing therapies that defend against complications, according to Science Daily.

People with chronic kidney disease have much higher risk of cardiovascular disease, the leading cause of death for those with type 1 diabetes. The team demonstrated that the eye condition known as proliferative diabetic retinopathy also is independently associated with cardiovascular disease.

Study proves ‘muscle memory’ exists at a DNA level

A study led by researchers has shown for the first time that human muscles possess a 'memory' of earlier growth -- at the DNA level.

Periods of skeletal muscle growth are 'remembered' by the genes in the muscle, helping them to grow larger later in life, according to Science Daily.

The research could have far-reaching implications for athletes caught using performance-enhancing muscle building drugs -- as the drugs could be creating long-lasting changes, making short-term bans inadequate.

An afternoon nap is as good as a caffeine boost, claims sleep expert

The benefits of having a nap during the day are similar to those experienced after consuming caffeine, according to a sleep expert.  

By having a snooze instead of a coffee or tea the side effects of dependence from a stimulant, including disrupted sleep at night time, can avoided, according to Daily Mail.

That's according to Dr Nicole Lovato, postdoctoral research fellow.

Her research also found that those who regularly nap report feeling more alert after a brief nap in the afternoon when compared to those who only nap occasionally.

She points out another research group found that motor learning, which is where brain pathways change in response to learning a new skill, was significantly greater following a brief afternoon nap for regular nappers when compared to non-nappers. 

Curcumin improves memory and mood

Lovers food, give yourselves a second helping: Daily consumption of a certain form of curcumin -- the substance that gives Indian curry its bright color -- improved memory and mood in people with mild, age-related memory loss, according to Science daily.

The research, examined the effects of an easily absorbed curcumin supplement on memory performance in people without dementia, as well as curcumin's potential impact on the microscopic plaques and tangles in the brains of people with Alzheimer's disease.

Choose Omega-3s from fish over flax for cancer prevention, study finds

Omega-3s from fish pack a stronger punch than flaxseed and other oils when it comes to cancer prevention, according to Science Daily.

Prof. David Ma has discovered that marine-based omega-3s are eight times more effective at inhibiting tumour development and growth.

"This study is the first to compare the cancer-fighting potency of plant- versus marine-derived omega-3s on breast tumour development," said the professor in the Department of Human Health and Nutritional Sciences. "There is evidence that both omega-3s from plants and marine sources are protective against cancer and we wanted to determine which form is more effective."
