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

Even before he became president, Donald Trump was no fan of the Oscars. "The Oscars are a sad joke, very much like our President. So many things are wrong!" Trump tweeted in 2015, just before announcing his run for president."I don't know how much longer I can take this bullsh*t - so terrible! #Oscars" Trump tweeted a year earlier.Well, if Trump were watching the 2019 show, he likely wouldn't be happy at some of the jokes made at his expense.Comedienne Maya Rudolph broke the ice early in the show by commenting on President Trump's recent national emergency declaration — a move he made in order to secure funding to build a border wall with Mexico."There is no host, no popular movie category and Mexico is not paying for the wall," Rudolph said.While introducing winner for Best Foreign Language Film, actor Javier Bardem also addressed Trump's proposed wall — doing so in Spanish.ABC translated Bardem's speech in real time."There are no borders or walls that can restrain ingenuity or talent. In any region of any continent, there are always great stories that move us. And tonight, we celebrate the excellence and importance of the cultures and languges of different countries," Bardem said.Immediately following Bardem's comments, comedian Keegan Michael Key appeared to poke fun at Trump after dropping into the Dolby Theater from the ceiling with an umbrella, a la Mary Poppins. After a few seconds of fiddling, Key simply laid the open umbrella on the ground — just as Trump did in 2018 when boarding Air Force One. 1541

Exposing skin to sunlight is a convenient way to meet our vitamin D needs, which is crucial for bone health. That might make you wonder: Does wearing sunscreen interfere with vitamin D levels and potentially cause vitamin D deficiency?The short answer is yes. But before you toss your SPF 30, dermatologists say the relationship between sunscreen and vitamin D is much more nuanced than that.According to Dr. Henry W. Lim, chair emeritus of the department of dermatology at the Henry Ford Health System and former president of the American Academy of Dermatology, if sunscreen is supplied in a thick layer it "can effectively block sunlight and cause a lack of vitamin D synthesis in skin," Lim said. A thick layer is defined as roughly equivalent to about 1 ounce, or the size of one golf ball, for the full body, he said."However, in the real world ... most people apply less than this amount," Lim added. In other words, "the 'in use' SPF is actually lower than the labeled SPF."So, you may not have to worry about vitamin D deficiency if you're not putting enough sunscreen on in the first place. 1113

EL PASO, Texas — There's a work of art going up on a wall in El Paso, Texas. The man behind it is Manuel Oliver. He lost his son, Joaquin, in the Parkland school shooting.Sunday would've been Joaquin's 19th birthday.Oliver was already scheduled to be in El Paso, Texas, this weekend, putting a mural up at an immigrant advocacy center, when the mass shooting happened Saturday."Because it is his birthday, we always try to put together things that Joaquin would do," Oliver said. "And this is something that Joaquin will be very happy to do. Scream out his support for the immigrants."He is continuing with the mural, but hasn't said what it will be yet, only saying it will show support for the city of El Paso. People will have to just wait until it is revealed."This is the reason why we are here," the artist said. "Now, yesterday, 29 people were shot down, just like Joaquin.“It's very painful. And, um, I think ... somebody needs to do the dirty job."Murals like the one he is painting in El Paso have been Oliver's post-Parkland calling.“I'm not taking this as a new norm, " Oliver said. "I won't. I'm not accepting that my son was shot down and I should do nothing. I won’t have that as an option. Actually I’m gonna quote my beautiful son Joaquin now. F*** that."The artist also has a message for El Paso and the rest of the country."You have to stay strong. This shouldn't be a surprise for this nation, unless we do something, unless we are louder with our message, things will stay the same," Oliver said. "Let's not take this as a tradition and let's fight for our loved ones that cannot use their own voices to let politicians here them. Be strong, and we're with you." 1695

Facebook on Thursday began taking down ads for the reelection campaign of President Donald Trump that direct people to a survey labeled a “census,” hours after House Speaker Nancy Pelosi said people would confuse it with the once-a-decade head count.Facebook said in a statement that it was enforcing its policies to prevent confusion over the 2020 census, which begins next week for most people.“There are policies in place to prevent confusion around the official U.S. Census and this is an example of those being enforced,” the Facebook statement said.Earlier in the day, Pelosi had called the survey sponsored by the Trump reelection campaign, “an absolute lie.”“A lie that is consistent with the misrepresentation policy of Facebook,” Pelosi said. “But now they’re messing with who we are as Americans. I know the profit motive is their business model, but it should not come at the cost of counting who is in our country.”The ad says, “President Trump needs you to take the Official 2020 Congressional District Census today.” Clicking on a red button saying “Take the Survey” leads to a website with questions asking visitors about party affiliation, whether they intend to support Trump and which media organizations they get their information, among other questions.Similar mailings have been distributed around the U.S.On Thursday, four Democratic House members — Reps. Carolyn Maloney of New York, Jamie Raskin of Maryland, Gerry Connolly of Virginia, and Katie Porter of California — demanded in a letter that the Republican National Committee stop any mailings or online ads that resemble Census Bureau documents.In a statement, the Republican National Committee said it would add language to future mailings, making it clear what it is.“This is a standard direct mail piece that has been utilized for decades. These mailers are fully compliant with the law, clearly marked as a fundraising solicitation from the Republican National Committee, and in no way resemble the official government census,” the RNC statement said.Census Bureau officials have been on high alert for online misinformation aimed at confusing people about who is eligible to fill out the form or how to properly file it, along with imitation websites posing as the official census site.The bureau has spent the last year forging relationships with the major tech platforms -- Facebook, Twitter and Google — to put out accurate information about how the census works and yank misinformation about the form from their sites.In January, Facebook began banning ads that discourage people from participating in the census or portray it as “useless.” The ban applies to ads on both Facebook and Instagram, which Facebook owns. The platform also announced that misleading posts about the census would be subject to removal. Typically, the platform does not remove false or misleading content from its site, unless it gives wrong information about voting.The Trump campaign on Tuesday began running different versions of the census ad on Facebook across the country from Trump and Vice President Mike Pence’s official Facebook page. The campaign purchased thousands of the online ads that were viewed thousands of times before Facebook began removing them Thursday. Former Census Bureau director John Thompson said the Trump campaign has put a new spin on an old campaign strategy: For years, Republicans have sent fundraising mailers that mimic the census.Although it’s hard to tell if those tactics have had any impact on the response rate to the census, Thompson said “the less confusion, the better” when it comes to the once-every-decade survey.Trump’s ads and the Republican mailers could dupe some people into thinking they’ve already filled out the official census form, and if there’s any consequence at all, it could be that the move backfires on Trump’s own supporters, Thompson said.“I don’t know that they would want to have confusion,” said Thompson, who served in the Obama administration. “It could have a reverse impact on the Trump administration, (it) could create an under-representation of their constituents in the census.”Meanwhile, in the U.S Senate, Democratic senators told U.S. Commerce Secretary Wilbur Ross, whose department oversees the U.S. Census Bureau, they felt misled by his testimony almost two years ago on the origins of a failed citizenship question. Ross was testifying Thursday before the Senate Committee on Appropriations.The U.S. Supreme Court blocked the Trump administration last summer from adding a citizenship question to the 2020 questionnaire. The administration had said the question was being added to aid the Justice Department in enforcing a law that protects minority voters’ access to the ballot box. But the high court said the administration’s justification for the question “seems to have been contrived.”Opponents argued it would have intimidated immigrants, Hispanics and others from participating in the once-a-decade head count that determines how .5 trillion in federal spending is allocated and how many congressional seats each state gets.“Your statements were totally false,” Democratic U.S. Sen. Patrick Leahy of Vermont told Ross during the hearing. “There is now an avalanche of evidence showing you repeatedly pressured both the Justice Department and the Census Bureau for nearly a year to support adding the question.”Ross denied misleading the senators.“”My statements were correct then. They were true then. They are correct now. They are true now,” Ross said.Leahy responded, “The evidence we’ve seen shows they were not true.”This is the first census in which the Census Bureau is encouraging most people to answer the questionnaire online, although people can still answer the questions by telephone or by mailing in a paper form. Residents can start answering the form next Thursday.Separately, a federal judge in Maryland on Thursday denied a request for a preliminary injunction in a lawsuit the NAACP had filed against the Census Bureau, claiming its preparations for the 2020 census were ina
