Location of body fat can increase hypertension risk

A new study published in the Journal of the American College of Cardiology found that abdominal fat is more strongly associated with high blood pressure risk than overall obesity. The research, which followed 903 patients for seven years, discovered a significant correlation between retroperitoneal fat and hypertension.

ATLANTIC -- ambulance administration of anti-clot drug may benefit heart attack patients

A new study found that early administration of ticagrelor, an anti-clot medication, in the ambulance may prevent stent thrombosis in heart attack patients. The ATLANTIC study showed a significant reduction in stent thrombosis at 24 and 30 hours in the ambulance treatment arm compared to the in-hospital treatment arm.

Scientists devise a bar code for the bacteria that causes tuberculosis

Researchers have devised a genetic barcode that can identify different types of tuberculosis (TB) bacteria, allowing doctors to track the spread of the disease more effectively. The study found that just 62 mutations are needed to code the global family of strains, making it easier for scientists to map how TB moves around the world.

Singaporean birth cohort study finds benefits for babies exposed to 2 languages

A Singaporean birth cohort study found that six-month-old bilingual infants outperformed monolingual peers in recognizing familiar images and paying attention to novelty. This suggests a generalized cognitive advantage that emerges early in bilingual children, which may have implications for their future pre-school developmental outcomes.

Zooming in for a safe flight

A new study reveals that bats process complex spatial information by dynamically adapting their brain maps to external factors. By enhancing neuronal signals for objects in close proximity, bats can magnify the appearance of nearby obstacles, enabling them to navigate safely.

Low-carb vs. low-fat diets

A low-carbohydrate diet is more effective than a low-fat diet in reducing body weight and cardiovascular risk factors. The study found that participants on a low-carb diet experienced greater decreases in weight, fat mass, and other cardiovascular risk factors compared to those on a low-fat diet.

Computer simulations visualize ion flux

A team of researchers used computer simulations to study how ion flux works in voltage gated sodium ion channels. The results revealed that a specific amino acid, glutamic acid, plays a crucial role in regulating channel flux and enabling selective sodium influx.

Spinach extract decreases cravings, aids weight loss

A study published at Lund University found that spinach extract containing thylakoids reduces hedonic hunger by up to 95% and increases weight loss by 43%. The study showed improved appetite control, healthier eating habits, and increased weight loss in participants who took the thylakoid extract before breakfast.

Nature's tiny engineers

Scientists at MIT and Weizmann Institute found that corals actively engineer their environment to enhance nutrient exchange through turbulent flows. The cilia on coral surfaces produce strong swirls of water that draw in nutrients while driving away waste products.
