Missing sleep may hurt your memory

Lack of sleep, already considered a public health epidemic, can also lead to errors in memory, and finds a new study by researchers according to Science daily.

The study, found participants deprived of a night's sleep they were shown in a series of images.

"We found memory distortion is greater after sleep deprivation," said Kimberly Fenn, associate professor of psychology and co-investigator on the study. "And people are getting less sleep each night than they ever had."

Drinking 3 cups of coffee a day reduces the risk of dementia

Drinking three cups of coffee a day reduces the risk of dementia, scientists claim according to Daily mail.

Moderate caffeine consumption is known to prevent the formation of toxic clumps in the brain linked to Alzheimer's disease.

But a new report shows long-term intake helps to fill the body with powerful antioxidants that boost cognitive function.

However, it could also prevent Parkinson's and other neurological disorders, an analysis funded by six of Europe's biggest coffee companies found.

Experts have been at loggerheads over whether coffee is bad for the body for years.

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.
