A team of researchers said Wednesday that it had produced embryonic stem cells — a possible source of disease-fighting spare parts — from a cloned human embryo. Scientists at the Oregon Health and Science University accomplished in humans what has been done over the past 15 years in sheep, mice, cattle and several other species. The achievement is likely to, at least temporarily, reawaken worries about “reproductive cloning” — the production of one-parent duplicate humans. But few Read more

Red meat links to heart disease

A chemical found in red meat helps explain why eating too much steak, mince and bacon is bad for the heart, say US scientists. A study in the journal Nature Medicine showed that carnitine in red meat was broken down by bacteria in the gut. This kicked off a chain of events that resulted in higher levels of cholesterol and an increased risk of heart disease. Dieticians warned there may be a risk to people taking carnitine supplements. There has been a wealth of studies suggesting that Read more

Writing in the journal Proceedings of the National Academy of Sciences, the researchers said the results helped explain how poor sleep damaged health. Heart disease, diabetes, obesity and poor brain function have all been linked to substandard sleep. What missing Read more

All patients will soon have their tumour’s DNA, its genetic code, sequenced, enabling doctors to ensure they give exactly the right drugs to keep the disease at bay. Doctors hope it will be an important step towards transforming some types of cancer into a chronic rather than fatal disease. The technique could enable terminally ill patients, who can currently expect to live only months, to carry on for a decade or more in relatively good health, according to specialists at Read more

He had a surgeon explore the area, and the diagnosis was pancreatic cancer. This surgeon was one of the best in the country.

Charlie was uninterested. He went home the Read more

The researchers who first identified the link said the number of drugs that became dangerous with grapefruit was increasing rapidly. They were writing in the Canadian Medical Association Journal. The team at the Lawson Health Research Institute in Canada said the Read more
