4 . In 1953，a mountain climber reported seeing a bar-headed goose soar over the peak of Mount Everest (珠穆朗玛 ).   It was thought impossible.   Now researchers who raised 19 of the geese—named for the black stripes on the backs of their heads—have shown the birds really fly so high.

The team trained the youngsters to fly in a large wind tunnel wearing backpacks and face masks full of sensors that recorded their heart rate. blood oxygen levels, temperature, and metabolic rate—how many calories they burned per hour. The researchers simulated(模拟)10w-, medium-, and high-altitude conditions by altering the concentration of oxygen supplied to face masks worn by each goose as it flew in the tunnel.

Birds already have a better heart and lungs than mammals for sustained physical activity. And researchers knew that bar-headed geese have even larger, thinner lungs that let them breathe more deeply and an even bigger heart to pump more oxygen to muscles than other birds.

The wind tunnel experiments showed that when the concentration of oxygen was at its lowest-like the 7% found on top of Mount Everest versus 21% at sea level—the geese's heart rate and frequency of wing beats remained the same even as their metabolic rate dropped. Somehow, the birds managed to cool down their blood-the measured blood temperature droppedso it could take in more oxygen, the researchers report today in eLife. This cooling likely helps compensate for the very thin air, the team says.

Although well trained, the birds were only willing to stay in the air a few minutes-or Iesswhen wearing their backpacks and flying at 6ihigh" altitudes. So it's not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest.

5 . Here are the top summer vacation lodges in the nation!

Out of Lake Wobegon; Fair Hills Resort

With sandcastle contests, Swedish buffet night, and family bingo, this classic northern Minnesota lodge is right out of Garrison Keillor's Lake Wobegon. Families can choose from a collection of activities suitable for both adults and kids—volleyball, tennis, sailing, swimming—laze by the lake, or rehearse for their star turn at the weekly talent show. The family-run resort is proud of its myriad "lifers," guests who've been vacationing here since they were kids. This year, ten of them will celebrate their 50th yearly visit.

Northern California, Unplugged; Gray Eagle Lodge

Once they find Gray Eagle Lodge off a two-lane road, most guests have no use for their cars. Days here are spent on foot, hiking to alpine lakes in the Sierras or going for a dip in the swimming hole fed by a 15-foot waterfall. "There are no officially planned activities," explains Tracy Morris, who has taken her children here for years, "unless you count the get-togethers specifically arranged for kids who have never met before but have become fast friends and enjoy fun together."

Authentic Adirondacks; The Hedges

For recent years improvements have been made—including upgrading the plumbing to accommodate more guests, answering to the main complaints in the past about its poor capacity. The current owners have restored the camp to its original Adirondack-style glory. Though tasteless to the younger age groups, the style earned the lodge a spot on the National Register of Historic Places.

Great Lake Lodge; The Inn at Watervale

Built as a boarding school in 1892, this lodge became a summer retreat in 1917. Today, the owner of the lodge proudly promotes the resort's lack of TV, Wi-Fi ,and decent cell phone coverage, which makes it perfect for recluses(隐士).   Instead of sticking with their smartphones, parents and children both find their relationships greatly improved through hiking the 300-foot-high Old Baldy dune, combing the beach for fossils, and savoring the sunsets over the lake together.

6 . The insects are important to farmers. When a honeybee lands on a flower in plant, pollen (花粉) sticks to its legs. When the bee lands on another flower, some of the pollen falls off and fertilizes the second plant.

The act of spreading pollen is responsible for many fruits, vegetables, nuts and other crops. Yet about 30 percent of honeybees in the United States and other areas have died in recent years.

Mike Leggett is a researcher at the University of Maryland. He wants to learn why so many bees are dying. “The number of colonies (蜂群) that die every winter has been one in three. So on average 30 percent of the colonies have died every winter over the last six winters. And that’s a huge number.” His research team examined the pollen that honeybees carried to their homes. They found that the pollen contained high levels of 35 different pesticides (杀虫剂), which are chemicals used to protect plants. “Pesticides are used, and have been used, pretty widely, for centuries, to protect plants from diseases,” says Mr Leggett.

Keith Oh linger, a farmer and beekeeper in Maryland, has watched many of his bees die every winter. Mr Ohlinger thinks widespread bee death is caused by several things happening at once. But he does not feel sure that pesticides are a part of the problem, “I felt it was the result of a lot of little things. I didn’t feel that there was probably one smoking gun. But there’s a division (分歧) there, some people feel that it is just one thing.”

Honeybees are important to agriculture. This makes the search for an answer to their death very important for Mr Leggett’s team. As he knows, one in every three bites of food we eat is somehow pollinated by honeybees.
