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

Donald Trump's lawyers want the Washington court fight over Trump's accounting records to slow down.A recent congressional subpoena for the records could reveal financial information about Trump to Democrats in Congress, but the President says a federal judge is moving too quickly.On Monday, private attorneys representing Trump and his companies disagreed with a federal judge's decision to hold a comprehensive court hearing about the subpoena on Tuesday in Washington, according to court filings.The President's attorneys say they are not being given a fair shot in court, and have asked the judge to either narrow the topics covered in the hearing Tuesday or cancel the hearing outright."Because the hearing is tomorrow, the court's consolidation will force plaintiffs to try their case on only four days' notice, with no discovery, with little opportunity to assemble evidence, before Defendants have filed a single pleading, with no idea which facts are actually in dispute, and without a round of briefing focused on the merits," the President's legal team wrote.Congress' attorneys, however, said they are ready for the case to proceed as scheduled on Tuesday and do not want Tuesday's hearing to be canceled. The scheduled court hearing would be the first in a growing set of legal disputes between the Democratic-led House of Representatives and those it has subpoena for Trump's financial records.So far, Trump has sued the accounting firm Mazars USA as well as two banks, Deutsche Bank and Capitol One, to stop them from fulfilling House subpoenas. Separately, the Treasury Department has pushed back against Congress' request for Trump's tax returns held by the IRS.The accounting firm and banks haven't taken sides in the cases. Instead, the House general counsel is arguing opposite Trump to Judge Amit Mehta.In this case, the Democratic-controlled House Oversight Committee initially subpoenaed Mazars for all financial statements, communications and other documents related to Trump, a handful of his companies and his foundation from 2011 through 2018.Mazars became a target in the House investigation after former Trump personal attorney Michael Cohen accused Trump of fudging his wealth in an unsuccessful attempt to buy the Buffalo Bills football team and reduce his real estate tax burden.The committee sought the accounting firm's information on Trump by April 29.After Trump sued, Mehta temporarily halted the subpoena and was going to consider further questions about keeping the documents from Congress as the case progressed. But last Tuesday, Mehta said he was ready to hear the full arguments about the case in court, meaning his decision could come far earlier than previously expected.The House has argued that it has the authority to subpoena Trump's information, and says it is investigating potential constitutional, conflict of interest and ethical questions related to Trump's financial holdings. "The Committee is determining what legislation is required to ensure full public confidence in the officials charged with executing the nation's laws," the House wrote in a filing earlier this month.Trump's attorneys, conversely, say the President is being targeted by the Democrats for political reasons--that the subpoena doesn't have a legislative purpose. They also argue Trump will be harmed if his private information from his accountant is exposed.Generally, federal courts have refrained from limiting Congress' abilities.The House Financial Services and Intelligence committees are also investigating the President's finances and have delivered subpoenas to Deutsche Bank, Capitol One and other major banks.Trump, his businesses, and three of his children -- Ivanka, Donald Jr. and Eric -- are suing in New York federal court to stop the subpoenas to those banks and won't be heard by a judge until next week. 3864

Facebook CEO Mark Zuckerberg sought to recast the challenges facing his company in a historical light on Thursday, describing social media as a kind of "Fifth Estate" and describing politicians' calls to clamp down on tech companies as an effort to restrict the freedom of expression.In a speech citing landmark Supreme Court cases and historical figures such as Frederick Douglass, Zuckerberg told an audience at Georgetown University that during times of social upheaval, policymakers have instinctively sought to limit the freedom of speech."The impulse is to pull back from free expression," he said. But, he continued, "We are at a crossroads. We can either stand for free expression ... or we can decide the cost is simply too great. We must continue to stand for free expression."Zuckerberg had 814
