The heart: Digital or analog? Researchers shed dramatic new light on disorders of heart bioelectricity

Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have found evidence that may disrupt conventional understanding about how electrical activity travels in the heart—a discovery that potentially can lead to new insight into medical problems such as heart arrhythmia and sudden cardiac death. The research study, now online but scheduled to appear as a final version on Tuesday, Sept. […]

Happy elderly people live longer, say researchers

Happy older people live longer, according to researchers at Duke-NUS Medical School in Singapore. In a study published today in Age and Ageing, the scientific journal of the British Geriatrics Society, the authors found that an increase in happiness is directly proportional with a reduction in mortality. The study utilised data for 4,478 participants of a nationally representative survey to […]

New target could prevent progression of liver damage to cancer

Problems like obesity and alcoholism appear to chronically trigger in the liver a receptor known to amplify inflammation in response to invaders like bacteria, scientists report. The relentless, increased activity of TREM-1 in turn accelerates injury and scarring of the liver, a first step toward cirrhosis and liver cancer, says Dr. Anatolij Horuzsko, reproductive immunologist in the Georgia Cancer Center […]

Oxygen therapy for patients suffering from a heart attack does not prevent heart failure

Oxygen therapy does not prevent the development of heart failure. Neither does it reduce the long-term risk of dying for patients with suspected heart attack. This has been proven for the first time by researchers at Karolinska Institutet as a result of a major Swedish study. The study is to be presented at the European Society of Cardiology’s (ESC) cardiology […]

Research discovers new channel-gating mechanism

Computational biophysicists are not used to making discoveries, says Jianhan Chen at the University of Massachusetts Amherst, so when he and colleagues cracked the secret of how cells regulate Big Potassium (BK) channels, they thought it must be a computational artifact. But after many simulations and tests, they convinced themselves that they have identified the BK gating mechanism that had […]

This Timeline of Breastfeeding Barriers Will Remind You That Moms Are Almost Too Strong

Breastfeeding is one of the most effective ways to ensure your baby’s health and survival according to the World Health Organization. But globally, only 40 percent of infants under 6 months of age are exclusively breastfed — and for myriad reasons, many of which have to do with breastfeeding complications. Of course, some women do not breastfeed by choice and […]
