Why women live longer than men

Women are genetically programmed to live longer than men, a study has found according to Daily mail. 

It is well known ladies tend to live longer than gentlemen.

But now scientists have discovered that this 'male disadvantage' is not just a human phenomenon – because of men having higher likelihoods of men dying in war, violence or exposure to industrial accidents.

A study of monkeys and apes find that males in primate species also live shorter lives.

The study, analysed data from more than one million births and deaths from the 18th century to the present day.

Missed connections: As people age, memory-related brain activity loses cohesion

Groups of brain regions that synchronize their activity during memory tasks become smaller and more numerous as people age, according to a study.

Typically, research on brain activity relies on average brain measurements across entire groups of people. In a new study, Elizabeth Davison, and colleagues describe a novel method to characterize and compare the brain dynamics of individual people.

The researchers used functional magnetic resonance imaging (fMRI) to record healthy people's brain activity during memory tasks, attention tasks, and at rest. For each person, fMRI data was recast as a network composed of brain regions and the connections between them. The scientists then use this network to measure how closely different groups of connections changed together over time.

They found that, regardless of whether a person is using memory, directing attention, or resting, the number of synchronous groups of connections within one brain is consistent for that person. However, between people, these numbers vary dramatically.

Dengue fever kills 20 in Burkina Faso

Dengue fever has killed at least 20 people in the West African state of Burkina Faso, where about 2,000 cases of the disease have been recorded.

Dengue is a mosquito-borne disease which is prevalent in sub-tropical and tropical regions, according to BBC.

It is a major cause of illness worldwide, causing about 100 million episodes of feverish illness a year.

Want to keep your memory as you grow older? Revealed, the 6 foods to boost your brain power

Are you doing what you can to nourish your brain?

Making sure you get as many nutrients as possible helps to optimise your focus, concentration, memory and even intelligence according to daily mail.

Here, Cassandra Barns, a nutritionist reveals the six best foods to boost your brain power.

Oily fish such as salmon are high in omega-3 fatty acids called DHA.

DHA is found in high levels in the grey matter of our brain – proof that we need lots of it for healthy brain function!

Researchers have suggested that having plentiful supplies of DHA supports learning and memory, as well as IQ.

Walking may help protect kidney patients against heart disease, infections

Heart disease and infection are major complications and the leading causes of death in patients with chronic kidney disease. It is now well established that immune system dysfunction is involved in both of these pathological processes. Specifically, impaired immune function predisposes to infection, while persistent immune activation leads to a state of chronic inflammation that can damage the insides of blood vessels and increase heart disease risk. Physical exercise may confer benefits by exerting anti-inflammatory effects and enhancing immunity, but such effects have been largely unexplored in kidney disease.
