Berries, apples and tea can do wonders for your brain

If you'e looking for an easy way to keep your brain healthy, consider eating more berries, consuming more applies and drinking tea. There's good science to support the benefits of getting started early eating a healthy diet for preventing Alzheimer's disease and other forms of dementia. 
Alzheimer's risk significantly lower for older adults who consume these foods
Tufts University scientists looked at Alzheimer's disease risk among older adults and compared those that consumed scant amounts of apples, tea and berries that are loaded with antioxidants; published in the Journal of Clinical Nutrition. 
The study finding was based on conclusions extracted from dietary questionairres submitted during medical exams among heart disease risk patients participating in the Framingham Heart Study. 
One of the important highlights of this study, compared to others is that the risk of the brain disease was analyzed over a 20 year period, versus short term studies that have been pub…

Researchers find a way to make air pollution harmless using graphene composite

A team of researchers has  found a way to render smog that causes air pollution harmless,  using a coated graphene composite


The implications for human health could mean fewer incidences of childhood respiratory diseases, heart problems and so much more


Pollution that comes from industry and motor vehicle exhaust fumes have been a growing problem and concern of the World Health Organization. 


Health experts have repeatedly warned lawmakers about the adverse effects of nanoparticles in the air that, if left unchecked, will continue to contribute to rising health costs and human suffering.’


According to the WHO, one out of every nine deaths have been linked to air pollution from nanoparticles. 


Air pollution  harms the body in ways that have been uncovered over the past decades. 


Lack of clean air in inner cities, underdeveloped countries and near freeways remains a concern, though some progress has been made thanks to government regulations; some of which have been rolled back, much to the chagrin of the public health sector. 
What scientists are doing


The Graphene Flagship team, in conjunction with Italcementi, HeidelbergCement Group, Italy, have produced a new graphene-titania composite that when exposed to sunlight removes nitric oxides from the air. 


The coating on the titania that is newly developed “depollutes” the air.

The graphene composite can be applied to concrete or building walls. The  byproducts are environmentally friendly and wash away with rain or cleaning.


Xinliang Feng, Graphene Flagship Work Package Leader for Functional Foams and Coatings, explained in a press release:  “Photocatalysis in a cementitious matrix, applied to buildings, could have a large effect to decrease air pollution by reducing NOx and enabling self-cleaning of the surfaces – the so-called “smog-eating” effect.”

NOx is a volatile compound found in VOCs or volatile organic compounds in particulate air matter that can enter the lungs leading to cardiovascular and respiratory problems.


The only thing needed is sunshine - and industries willing to make a somewhat pricey  investment to help keep people healthier.

Can you eat square or heart shaped Japanese watermelon?

Have you ever wondered if Japanese square watermelon tastes good?  What about heart shaped watermelon? Are Japanese watermelons edible? 

According to a new report from EmaxHealth.com, the fruits are not tasty. Watermelon has many known health benefits, but when you mess with mother nature to make a cubed or heart shaped watermelon you lost taste.

Why is it done?

According to EmaxHealth reporter Tamar Najarian:
"...by the time it [square watermelon] is the proper shape, it has not been given the time needed to also mature. As such, one can buy a non-edible square watermelon for nearly $100 from posh upscale supermarkets and use it as decoration or gifts that could last up to a year or more."  In Najarian's opinion that makes square watermelons pretty useless, despite the fact that they're produced to make them easier to store.. 

You can even grow your own square watermelon,

Heart shaped watermelon tasty

If you want something different to give as a gift, you could offer heart…

Better Health Through Compassion - Bloggers Unite for Refugees

There's no question that we can learn, but can we translate our learning into action? We face disasters, and none of us are immune. Hunger, climate change, and the threat of displacement from war and natural disasters are real. You could easily become a victim.

We are not disempowered. Helping others means learning more about what goes on in the world, and exploring initiatives. It's a matter of personal growth and sharing - and yes, it can help you remain healthier.

Blog Catalog has teamed up with Refugees United to do exactly that.

Creating change in the world means making a conscious effort. It takes compassion and maturity to get involved in helping others. Today's effort is directed at helping refugees.

There are currently an estimated 14 million refugees worldwide. They come from all cultures, and they are our kin. There are many ways to help. Choose just one. We all have the ability to do something positive.

Refugees can't go home - they have no home. They'…

Once a month shot for type 2 diabetes in the works that is also cheap

Anyone diagnosed with type 2 diabetes know it isn’t easy to manage blood sugar control. One of the barriers is the constant need for monitoring blood sugar and giving injections in the morning and evening - and for some, even more often.
Now there is a drug in development that means one injection that could last for 14-days. The implication is more freedom from the burdensome act of carrying around insulin.
Biomedical engineers at Duke University have developed a  technology that could replace daily and even weekly insulin injections for type 2 diabetes treatment.
What if you only needed insulin once a month?
The insulin is combined with a biopolymer that  keeps insulin circulating in the body for a longer period of time than what is currently on the market. The development could mean insulin injections could be given just once or twice a month, which could be life-changing for those trying to manage type-2 diabetes.
Current therapies that target insulin signaling molecules only last a …
