The idea of having a parasite infest your body is unsettling enough, but the case of a tapeworm that gave its human host cancer takes the grossness to an entirely new level.
The New England Journal of Medicine yesterday published a case study about a HIV-positive Colombian man who had tumours that yielded puzzling biopsy results: the cells were definitely cancer-like, but the cells were not human.
Three years of tests finally revealed the man had been infected by a tapeworm that had contracted cancer, which had then spread around the man’s body.
The man’s weakened immune system made him particularly susceptible to the tapeworm’s cancer cells, according to scientists and the US Centres for Disease Control and Prevention (CDC), which helped diagnose the man :: Read the full article »»»»

Chickens are evolving faster than previously thought, according to new research that challenges ideas of when they were domesticated and may have implications for human migration.
The findings, published in journal Biology Letters, are based on a genetic analysis of a chicken population that can be traced back over 50 generations.
The international team of researchers sequenced 12 mitochondrial genomes – DNA generally thought to be passed down from the mother to their offspring – in a well-known population of White Plymouth Rock chickens.
Previous chicken research – March 2014 – has been used to gauge human events in history, notably that Christopher Columbus beat Polynesians to South America :: Read the full article »»»»

The average height of European men rose by 11 centimetres between 1870 and 1980, an unprecedented spurt linked mainly to better health, smaller families and bigger incomes a new study says.
The review, published in the Oxford Economic Papers, is garnered from military, medical and other records for young adult males aged around 21 from 15 countries.
Northern European nations saw the largest growth in height between the two world wars. But those in southern Europe, a definition that includes France, had their increase post-World War II :: Read the full article »»»»

New Australian research has found men suffering even mild erectile dysfunction could have heart disease without knowing it. The Sax Institute’s 45 and Up Study is one of the largest on-going studies of healthy ageing in the world.
Doctors who looked at more than 95,000 men found that erectile dysfunction may be a symptom of cardiovascular disease. The study found that men with erectile dysfunction have a higher risk of being admitted to hospital with heart disease, even if they have no history of heart problems.
This is because erectile dysfunction can indicate problems with blood vessels and poor blood flow. The study notes that erectile dysfunction is common, with an estimated 40 per cent of men over 40 experiencing it :: Read the full article »»»»
