aScientists at the California Institute of Technology (Caltech) have reported evidence that Mars was warmer and wetter long ago than it is today. The Caltech scientists say they have directly established the temperature of Mars four billion years ago. At least, they established the surface temper...
One of the biggest concerns in science is bias(偏见)-that scientists themselves, consciously or subconsciously may put their thumbs on the scales and influence the outcomes of experiments.Boffins have come up with all sorts of strategies to try to remove it, from having their colleagues repeat ...

So, when a train came out of a tunnel, it could be very, very 5 . However, kingfisher birds hardly make a sound when they get into lakes or rivers. Engineers 6 a clever idea. They changed the front of the trains to match the shape of the kingfisher. Then the air could 7 pass ...
