Gabby Douglas stood beneath the Rio Olympic Arena, still in her Team USA leotard, trying hard to understand how she had become the most unpatriotic athlete in Rio. Tears filled in her eyes. She tried hard to talk but no words came out. Her pauses were long and uncomfortable.

    “I've been trying to stay off the Internet because there's so much negativity,” she said. The attacks against her have been everywhere these last few days. The bullies blamed her for not putting her hand over her heart while the US national song played. Besides, some other people attacked her for not jumping up and cheering hard enough for team-mates at the all-around final. All of this prompted her mother, Natalie Hawkins, to tell Reuters this weekend, that Douglas is “heartbroken”.

    It showed on Sunday, in Douglas's final performance of this Olympics and maybe in the Games ever. Douglas finished sixth in the uneven bars, far from the medal stand she owned four years ago in London, and shook her head, confused. What had she done wrong? Nothing made sense.

    “I mean, you do [Olympics] for your country, and you do it for yourself, how have I offended them? What have I done? I was standing in respect for USA. I'm coming out there representing them to the best of my abilities, so how would I be in disrespect?

    In 1869, the Smiley family purchased an area of land about 100 miles north of New York City. Over time, some of their property and much of the surrounding landscape became the Mohonk Preserve, which has since grown to 8,000 acres and attracts visitors and rock climbers.

    But the Mohonk Preserve also has a long scientific legacy. In the 1930s, Dan Smiley, a descendent of the original owners, began keeping track of the plants and animals that lived in the area.

    Megan Napoli is a research ecologist with the Mohonk Preserve in New York. She thinks Smiley's efforts produced a rare long-term data set of observations, which is useful for studying the impacts of climate change. For instance, other research has shown that songbirds are migrating north earlier and earlier in the spring.

    It's important for the birds to arrive at the proper time in the spring, because they need to time their arrival with the insect emergence. So they need to be here to establish their nesting sites, lay their eggs. Once the eggs hatch, they have their baby birds, so they need to time it when the insects are most abundant.

    Napoli has begun analyzing about 76,000 observations of songbird migration dates collected by Smiley and his team to see if they, too, show that climate change has altered the timing of migrations. Her results suggest that they do.

    Napoli found that short-distance migrants that spend their winters in the southern U. S. now arrive an average of eleven days earlier than they did in the 1930s. Long-distance migrants that overwinter in the tropics arrive roughly a week earlier. Napoli presented her results at a recent Ecological Society of America meeting in Portland, Oregon.

    Meanwhile, who knows how many other long-term, personal data collections like Smiley's are out there, waiting to be discovered and to help improve official attempts to track the planet's changes.

How to Drop a Pant Size in a Week

    Dropping one pant size in seven days is a difficult task, but with dedication, exercise and the right diet, you can make it happen.

    Increase your water consumption. Thirst is often misinterpreted as hunger, and if you are drinking the right amount of water, you will find it much easier to avoid snacking. Look to drink at around eight or nine glasses of water every day.

    Lower your calorie count. You can use a calorie calculator to determine how much you need to take in to maintain or lose weight If you take in fewer calories than you burn each day, you will lose weight as a result. As a rule, an average-sized woman needs to take in less than 1.300 calories per day for extreme weight loss, as you'll naturally burn around 2,000. Exact measurements differ based on age, height, weight and activity level.

    Cut the junk food. Chips, soda and candy seem harmless if taken as snacks, but can seriously affect your weight loss, Limit yourself to one or two snacks per day and switch your usual snack foods for baby carrots, apples and grapes.

    Break up your meals. If you want to lose weight, try eating four or five small meals per day instead of two or three large ones. This makes it easier for your body to process what you are consuming. Divide your required calories by the number of meals you'll be eating to determine how large each meal should be Space your meals out two or three hours apart—try meals at breakfast, mid-morning, lunch, afternoon and dinner.

    Doing intense aerobic (需氧的) exercise. You have to encourage your body to bum calories if you want to drop pounds and inches. Running is by far the fastest calorie burner, with the potential for 986 calories per hour. If you're unable to run, use an elliptical machine (椭圆机), jump rope, or participate in a high-impact aerobics class.
