Caffeine could protect the heart by helping it make energy, mouse study finds

Health
Coffee can do more than just keep people awake for the day -- studies have shown that moderate amounts of caffeine, like what's in coffee, can actually protect the heart. A new study looked at possible reasons for those beneficial effects, by studying the genes of mice. "We wanted to do this study to show people coffee is not as bad for your heart as people thought for a long time," co-author Dr. Judith Haendeler, medical faculty at the HHU Duesseldorf and IUF-Leibniz Research Institute for Environmental Medicine, told ABC News. But why could coffee-like caffeine levels be helpful for the heart? Building on their previous research that showed that caffeine could help with the repair of cells lining blood vessels, called endothelial cells, researchers at the Heinrich-Heine-University a...
Foods with carbs and fats together make the brain light up more, study finds

Foods with carbs and fats together make the brain light up more, study finds

Health
On a platter of cheese, pretzels and donuts, most people will probably reach for the donuts, according to a new study. That could be because the brain values foods like donuts, with both fats and carbohydrates, more than foods high in only fats, like the cheese, or only carbs, like the pretzels. People could be wired to want that deadly combo: Fats and carbohydrates together. "We were interested in exploring mechanisms that drive food reinforcement," lead author Dana Small, director of Yale University’s Modern Diet and Physiology Research Center, told ABC News. So how do the digestive and emotional system work for different types of macronutrients, like carbs and fats? And how do "man-made," processed foods that contain both fats and carbs affect these mechanisms? To find out, ...
Toddlers consuming too much added sugar, study finds

Toddlers consuming too much added sugar, study finds

Health
Toddlers in America are eating too much added sugar, and the problem only gets worse as they get older, a new study conducted by researchers at the Centers for Disease Control found. Extra sugar consumption has been linked to high levels of obesity, cavities, asthma, and risk factors for heart disease later in life. It's also been associated with higher cholesterol levels and elevated blood pressure. Added sugar is especially bad for children, as it sets diet preferences that could lead them to make poor nutritional choices later in life. The American Heart Association already recommends that children under the age of 2 avoid food with added sugars, including ready-to-eat cereals, baked goods, desserts, sugary drinks, yogurt, and candy. But researchers at the CDC found that some parents...
Keeping livers 'alive' boosts transplant success, trial finds

Keeping livers 'alive' boosts transplant success, trial finds

Health
Keeping donated livers "alive" with a machine prior to transplants boosts the chances of a successful operation, a landmark trial has found.Usually livers are kept in ice prior before the surgery, but many become damaged and unusable as a result. For this study, scientists put them in a perfusion machine, pumping the organs with blood, nutrients and medicines.More of these "warm" livers went on to be transplanted and showed less damage than the "cold" ones, the trial found.Scientists said the study could help to reduce the significant proportion of people who die waiting for a new liver and potentially "transform" how organ transplants are carried out. Record number of organ donors in 2017'Warmed liver' transplant first'Major impact'The randomised controlled trial involved 222 liver tran...
ESA's Mars Express finds possible supervolcano remnant

ESA's Mars Express finds possible supervolcano remnant

Science
April 13 (UPI) -- ESA's Mars Express has photographed a unique and mysterious geologic structure on the Martian surface.Astronomers aren't sure of the crater's origins. The crater, dubbed Ismenia Patera, may have been created by a meteorite impact. It's also possible the imprint was left behind by an ancient supervolcano.The layout and structural patterns seen in and around Ismenia Patera are different and more complex than the typical impact crater. Uneven lumps of rock are found scattered around the outer edge of the crater.Scientists believe the rocky deposits are debris ejected by neighboring impacts. These miniature impacts have created their own system of gullies inside Ismenia Patera.The crater's floor is dynamic, too, showing signs of movement. The floor is likely composed of a roc...
