To hear most recent rearch tell it, coffee is a miracle drink. The magic beans will ward off skin cancer and Alzheimer’s(老年痴呆症), reduce heart failure and diabetes（糖尿病） risks, heighten focus, and maybe even protect liver health. Oh, and decrea suicide risk, according to the newest study that validates our coffee addictions.
According to a study performed by the Harvard School of Public Health and published this month in The Worl d Journal of Biological Psychiatry, people who drink two to four cups of java each day are less likely to commit suicide than tho who don’t drink coffee, drink decaf, or drink fewer than two cups each day. The study followed ove r 200,000 people for at least 16 years. And it’s not just a weak link: the rearchers found that the suicide risk was cut by around 50 percent for coffee addicts.
This isn’t the first time that rearchers have discovered that coffee and smiles might go hand-in-hand. A 2011 study found that women who drink coffee cut their risk of depression by 15 percent compared to tho who don’t. Michel Lucas, the head rearcher of the most recent study, told The Huffington Post that coffee addicts can thank caffeine for the good news. The drug may actually act like a mild anti-depressant by tweaking levels of happy hormones .
八卦图方位图Of cour, there’s plenty of rearch out there that doesn’t look so kindly upon coffee drinkers. Recently, the New Yorker published an article arguing that while coffee may heighten focus, that means it also puts a squeeze on
creativity. And of cour, coffee’s well-known negative effects like insomnia(失眠症) and disturbed sleep cycles still hold.
Regardless, we’ll rai our mugs to this most recent study for justifying our coffee addictions once again.

But it turns out it might not be that simple .A new study by scientists at the U. S. Geological Survey (USGS ) underscores the fact that polar bears really are amazing swimmer. In fact they are so good that biologists were able to document 5 0 swims that cover an average length of 96 miles. the rearch provides clues that polar bears may
be able to keep treading(踩 ) water even as climate change melts their habitat.
The rearchers published their work in the Canadian journal of zoology . they followed 52 female polar bears in the Arctic Ocean north of Alaska from 2004 to 2009,using radio collars that could track the movements of the animals . They then compared the paths taken by the bears with maps of shifting a ice over the same period of time , and found that the polar bears were world - class marathon swimmers and tho long , long dips in the ocean weren't outliers—— while the really long -distance sw ims wer e re l ativel y ra t e, 3 8 % of th e be a rs surve ye d took at lea s t on e such mara thon swi m . 6 .
