Last year, about 28,000 men in United States died of prostate cancer, and still there is no effective, non-invasive test to diagnose the disease. Now, British researchers have come up with a non-invasive diagnostic tool that can ‘smell’ prostate cancer in the urine of men.

According to the National Cancer Institute, the test could offer hope for African-American men or the ones having a family history of prostate cancer. The two groups are thought to be more vulnerable to the disease.

A latest study has linked poor fitness during middle age to smaller brains nearly 20 years later. The study findings suggested that health and lifestyle choices can have a huge impact many years later by essentially shrinking the brains of ‘couch potatoes’.

Published online in the journal Neurology, the study included 1,094 participants. The average age of the participants was around 40, and at the start of the study, they were not suffering from heart disease, strokes, or dementia. They weren’t even consuming meds, known as beta blockers for lowering their blood pressure.

Some years back, scientists discovered stretches of Neanderthal DNA in living humans, and now they have found proof, described in a study appeared on Thursday in Science, that some of that DNA could help shape our health.

In case you bring out a comparison between Neanderthal skeleton and a modern human skeleton, the Neanderthal appears stocky, barrel-chested, and quite brutish. They were genetically different, however, nonetheless, to modern humans’ closest relative, Homo sapiens. They used to live in Europe and western Asia, whereas modern humans initially roamed in Africa.

Thereafter, nearly 60,000 years back, some of the modern humans become restless and moved to Eurasia. There they met the Neanderthals, and apparently some liked what they witnessed, thus had kids.

On Thursday, Venezuela's President Nicolas Maduro said that three people have lost their lives due to complications associated with the mosquito-borne Zika virus. Maduro said that Zika’s suspected cases had risen to 5,221.

Brazil said on Thursday that three people who lost their lives previous year suffered from Zika virus, though authorities don’t have any evidence that Zika solely was behind their deaths.

Just one in five people suffering from Zika experience illness and even then they are usually mild symptoms. Scientists so far haven’t succeeded in fully understanding the virus and so far there is no proof showing that it causes the birth deformations or any death reports.

In an announcement yesterday, Conservative Health Secretary Jeremy Hunt said he would impose an inferior contract on 55,000 junior doctors in England after it failed in reaching an agreement with the British Medical Association (BMA).

Addressing Parliament, Hunt said that the negotiator of the government Sir David Dalton had reached to an agreement on 90% of issues with the BMA, but so far no contract agreement had been finalized by a deadline of the earlier evening.

A new study has suggested that risk of dementia has been declining dramatically, but scientists don’t know reason behind the decline. Since the late 1970s, the chronic disorder of cognitive abilities is on the decline, as per the study featured in the New England Journal of Medicine.

For the last more than four decades, the risk of developing dementia has declined with a rate of 20% every decade. The study has released its results at a time when it was predicted that cases of dementia, also known senility, will loom in future.
