Versatile ultra-low power biomedical signal processor

At today’s International Solid-State Circuit Conference (ISSCC2011), imec, Holst Centre and NXP present a versatile ultra-low power biomedical signal processor, CoolBioTM, meeting the requirements of future wearable biomedical sensor systems. The biomedical signal processor consumes only 13pJ/cycle when running a complex ECG (electrocardiogram) algorithm at 1MHz and 0.4V operating voltage. This C-programmable chip is voltage and performance scalable supporting a frequency range of 1MHz up to 100MHz with an operating voltage from 0.4 to 1.2V.

Brain reward center responds to good and bad experiences

The so-called reward center of the brain may need a new name, say scientists who have shown it responds to good and bad experiences. The finding, published in PLoS One, may help explain the "thrill" of thrill-seeking behavior or maybe just the thrill of surviving it, according to scientists at Georgia Health Sciences University and East China Normal University.

Dual lab tests accurately predict vein graft blood clots in patients during CABG

A team of heart experts at Johns Hopkins has found that dual lab tests of blood clotting factors accurately predict the patients whose blood vessels, in particular veins implanted to restore blood flow to the heart during coronary artery bypass grafting, are more likely to fail or become clogged within six months.

New study provides insight into brain activity of depressed women responding to crying infants

Mothers who are depressed respond differently to their crying babies than do non-depressed moms. In fact, their reaction, according to brain scans at the University of Oregon, is much more muted than the robust brain activity in non-depressed moms.

Mutated cancer pathway studies identify therapeutic targets for congenital heart disease

Cross-disciplinary teams of scientists studying genetic pathways that are mutated in many forms of cancer, but which also cause certain forms of congenital heart disease - including hypertrophic cardiomyopathy, a thickening of the heart muscle that is the leading cause of sudden death in children and young adults -, have introduced these mutations into mice and successfully treated HCM in the lab.

New research: Fluid retention may explain drugs' risk of strokes and heart attacks

New research shows that medications which have raised safety concerns over heart attack and stroke risks may not have gotten approval from the Food and Drug Administration if the cardiovascular effects of fluid retention had been better understood. Fluid retention may explain the increased risk of heart attacks and strokes of medications such as Vioxx, Bextra, and Avandia.

Red and processed meats – How much to include in diet?

A latest Government-commissioned report advises people to eat less red meat and processed meat saying that it lowers the risk of developing cancer. The report will advise consumers eat no more than 2.5 oz (70g) of red or processed meat a day – the equivalent of three rashers of bacon. Also the weekly recommended limit is likely to be 1.1 lb (500g), the same as eating a large pack of minced beef, two 8oz steaks or four 4oz pork chops. The farming and retail industries are, as predictable, not happy with the directives.
