A study found that ghrelin hormone increases the appeal of high-calorie foods over low-calorie foods, suggesting a potential mechanism for weight loss. Ghrelin levels may help regulate calorie intake by altering food preferences during fasting periods.
A team of researchers used aerial photographs and field measurements to analyze the Canyon Lake flood, which excavated a 2.2-kilometer-long canyon in just three days. The study offers insight into ancient megafloods on both Earth and Mars, with findings that challenge traditional views of river canyon formation.
Scientists have discovered a 300m high ridge on the sea floor beneath Pine Island Glacier, causing it to accelerate its flow into the sea. The glacier's thinning ice allows warm ocean water to melt the underside, contributing nearly 10% of global sea level rise.
Scientists at Dana-Farber Cancer Institute found a way to disable MCL-1 protein, a common obstacle to chemotherapy treatment. The discovery suggests a new approach to target MCL-1 and make standard cancer drugs effective again.
A team of bioengineers from the University of Pennsylvania Institute for Medicine and Engineering developed a simulator to predict how blood platelets respond to various conditions during a heart attack or stroke. The model accurately predicted intracellular calcium signaling responses, even distinguishing between different donors.
A diet rich in antioxidants significantly improves insulin resistance in obese individuals with the metabolic syndrome. The study found that a daily intake of 800-1,000 milligrams of antioxidant-rich foods from fruits and vegetables enhances insulin sensitivity and reduces the risk of developing diabetes.
A new study found that living kidney donors with metabolic syndrome experience a decline in renal function more than twice as fast as those without the condition, highlighting the need for corrective measures before donation.
A laboratory study found that fructose makes fat cells in belly fat more mature and less responsive to insulin. The findings suggest a link between high fructose intake during childhood and increased visceral obesity, which raises cardiometabolic risk.
Researchers at MIT developed a new electrode material using carbon nanotubes, showing a significant increase in power capacity and stability. The material enables high-power outputs with good conductivity and efficient lithium storage.
