Drinking coffee could activate the body's fat-fighting defenses, a discovery that could have potential implications in the battle against obesity and diabetes.In a study published Monday, researchers at the University of Nottingham said that coffee may help stimulate our brown fat reserves, also known as brown adipose tissue, which play a key role in how quickly we can burn calories.There are two forms of fat cells, brown cells and white cells, and each plays a different role in our metabolism.While brown cells help generate heat, white cells are responsible for the storage of fat -- or, energy -- ready for release as needed. Levels of brown fat are known to be high in children but recent findings on the presence of brown fat in adults has restored hope to use them as targets to treat obesity."Brown fat works in a different way to other fat in your body and produces heat by burning sugar and fat, often in response to cold, said professor Michael Symonds, from the School of Medicine at the University of Nottingham, who co-directed the study."Increasing its activity improves blood sugar control as well as improving blood lipid levels and the extra calories burnt help with weight loss. However, until now, no one has found an acceptable way to stimulate its activity in humans."The scientists started by testing out coffee on stem cells to see if it would stimulate brown fat. Once they found the right dose, they moved on to humans to see if the results were similar.The team used a thermal imaging technique on four men and five women to trace the brown fat reserves and see how it produced heat."From our previous work, we knew that brown fat is mainly located in the neck region, so we were able to image someone straight after they had a drink to see if the brown fat got hotter," Symonds said.So will drinking a cup of coffee help you lose weight, as well as get out of bed?The study only involved nine people and the research is still at a very early stage. Scientists say they still need to determine what it is exactly about coffee that busts fat."The results were positive and we now need to ascertain that caffeine as one of the ingredients in the coffee is acting as the stimulus or if there's another component helping with the activation of brown fat," Symonds said."Once we have confirmed which component is responsible for this, it could potentially be used as part of a weight-management regime or as part of glucose regulation program to help prevent diabetes." 2507

Carbon monoxide poisoning at a motel in Canada sent 46 people to the hospital, including 15 in critical condition, city officials said.The fire department responded to an alarm at Super 8 Motel in Winnipeg, Manitoba, on Tuesday morning after carbon monoxide gas was detected in the building.At the scene, fire crews evacuated 52 people -- a majority of whom were hospitalized -- and one dog, the city tweeted Tuesday. Winnipeg Animal Services provided care for the dog."Today's incident at a Winnipeg hotel was not a gas leak. It was a carbon monoxide poisoning," Manitoba Hydro tweeted. "CO is produced by the incomplete combustion/ventilation of gas stoves, heating boilers, furnaces, propane barbecues, gas-powered water heaters & clothes dryers."The gas company said while natural gas has a rotten egg smell that helps with detection, carbon monoxide is odorless. For it to be detected, one needs a carbon monoxide alarm.The initial symptoms of carbon monoxide poisoning are flu-like, but without a fever. They may include dull headache, weakness, dizziness and nausea. High-level poisoning can result in vomiting, shortness of breath, confusion, blurred vision and loss of consciousness.When carbon monoxide levels are higher and develop more rapidly -- for example, from generators in residential spaces -- mental confusion can set in rapidly. Victims may lose muscle control without being aware of the flu-like symptoms and will probably succumb to poisoning if they are not rescued. 1506

Democrats concluded the second day of opening arguments in the impeachment trial of President Donald Trump on Thursday.Thursday marked the second of three eight-hour sessions in which House impeachment managers will explain why they feel President Donald Trump should be removed from office.On Wednesday, lead impeachment manager Adam Schiff walked Senators step-by-step through Trump's dealings with Ukraine, in which Trump withheld foreign aid for weeks in the hopes that it would encourage new Ukrainian President Volodymyr Zelensky to open an investigation into one of his political rivals."(The president) does not, under our laws and under our constitution, have a right to use the powers of his office to corruptly solicit foreign aid, prohibited foreign aid, to help his re-election," Schiff said during his remarks Thursday.Watch Thursday's session below:Democrats claim Trump abused the power of his office by withholding military aid to Ukraine — a U.S. ally and a key part of the U.S.'s defense against Russia — in exchange for opening an investigation that would be politically advantageous to Trump.Trump pushed Zelensky to announce that publicly that Ukraine was opening an investigation into Hunter Biden — the son of Democrat presidential candidate Joe Biden — and his role as a board member for the Ukrainian energy company, Burisma. While he was vice president, Joe Biden pushed for the firing of Ukrainian prosecutor Viktor Shokin, who was investigating Burisma. Obama administration officials maintain Shokin's firing was consistent with the U.S.'s strategy of rooting out corruption in Ukraine. During part of his remarks on Wednesday, Schiff pushed for Republicans to approve witnesses following opening arguments by both sides. "You should want the whole truth to come out. You should want to know about every player in this sordid business. It is within your power to do so," Schiff said.When setting rules for the impeachment trial, Republicans declined to include scheduled time for witnesses. Following opening arguments, senators most vote to approve additional witnesses with a majority vote. The Republican caucus currently holds a 53-47 advantage over the Democrat caucus, meaning four Republican senators would need to break party lines to approve witnesses.The Democrats' opening arguments will continue Friday when the trial resumes at 1 p.m. ET.Alex Hider is a writer for the E.W.
