New blood test that can detect 10 different types of cancer YEARS before someone gets ill

A blood test that can detect 10 types of cancer potentially years before someone becomes ill has been described as the 'holy grail' of cancer research.

Scientists in the US have found a simple test can pick up early signs of cancers including breast, ovarian, bowel and lung cancer.

It works by picking up fragments of DNA released into the blood by fast-growing cancer cells.

In a study of more than 1,400 people, the triple test achieved up to 90% accuracy.

Just 20 minutes of yoga or walking a day may keep your mind sharper in old age

Less than 20 minutes of light daily exercise - from walking to yoga - can prevent mental decline in old age, according to new research.

To protect thinking the exercise has to be over the long term - at least 52 hours over a period of about six months or two hours a week.

Yet this relatively small amount of physical activity boosts thinking - no matter what it is, say scientists.

A University of Miami study of more than 11,000 participants found that a mild exercise routine helped people stay sharp and perform mental tasks more quickly and effectively.


Eating spicy food cools you down better than ice cream

Is the blistering heat getting you all hot and bothered? Order up some fiery buldak (spicy Korean chicken), hunt down the spiciest chilli crab you can find, or tick the volcano-hot option on the mala hotpot order chit.

No, our brains have not been fried by the sun. As counter-intuitive as it sounds, bringing the heat to your mouth is actually a way to cool down.

When you drink an ice-cold beverage or eat ice cream, the hypothalamus (built-in thermostat in the brain) senses a drastic drop in your internal temperature. And because its job is to maintain things at 36.5 degrees Celsius, it cranks up your body temperature, causing you to feel warmer.

Eating spicy food does the opposite. Receptors in your mouth interprets the capsaicin component in chilli as a chemical action that creates a "hot" burning sensation, that causes the hypothalamus to counter the perceived temperature rise by increasing blood circulation and making the body sweat, hence cooling the body.

My 2 cents:
You may want to know that if you eat spicy food and got your tongue burnt, it is best to drink hot water. The hot water will counteract the spicy sensation and after a short while, your burning sensation will be gone.

Green tea could be key to preventing deaths caused by strokes and heart disease

Scientists had been researching epigallocatechin-3-gallate (EGCG), a compound found in green tea, for its ability to reduce amyloid plaques in the brains of Alzheimer’s disease patients.

However, a team from Lancaster University and the University of Leeds now believe EGCG can also break up potentially dangerous protein plaques found in blood vessels which can lead to an increased risk of heart attacks or stroke.

But, in the paper published in the Journal of Biological Chemistry, researchers said EGCG can bind to fibres in the tissue, converting them into smaller, soluble molecules less likely to cause damage.
