This includes a broad range of applied science-related fields, including engineering and medicine. By and large, he added, the U.S. science press has done “a pretty good job” of covering climate change. But “the political press doesn’t check. It tends to do ‘on the one hand, on the other hand.’ A lot of reporters simply will not go into issues like global warming with any understanding that the sides are not equal.” This bombardment of asteroids a few million years after the start of the solar system could have easily delivered enough ice — locked inside the rocks, safe from the sun’s heat — to account for Earth’s oceans, computer simulations indicate. Water makes up to about 20 percent of the mass of some of these asteroids. On Earth, despite having more than 70 percent of its surface blanketed in blue, water accounts for only 0.023 percent of the planet’s mass.
years ago, scientists warned of the ‘neglected dangers’ of heat islands

Only when the team downlinked additional images, captured in the minutes around the encounter, was the true nature of this object revealed. Observations over landcan be collected by weather stations, but the effort is more complicated at sea. In the early 20th century, before the advent of satellites, most maritime weather data were gathered voluntarily by sailors aboard commercial trading ships. Before this project, the observations “had never been seen by anybody else except the people who wrote them,” saysPraveen Teleti, lead researcher on the project and a climate modeler at the University of Reading in the United Kingdom.
Gwynne, now 72, is a bit chagrinned that from a long career of distinguished science and technology reporting, he is most remembered for this one story. It is commonly said that scientists should have a professional distance from what they study. To the extent that we can remove our biases and learn from multiple perspectives, we will understand our world better. Productivity and equity are probably the most often cited reasons to attend to diversity in science.

New Horizons, scheduled to pass by Pluto July 14, may learn whether the dwarf planet has rings, geysers and perhaps a subsurface ocean. Scientists are unsure if Titan’s ocean is thin and sandwiched between layers of ice or thick, extending down to the moon’s rocky interior.
NASA’s first look at a sample from asteroid Bennu reveals life’s building blocks
Gwynne was the science editor of Newsweek 39 years ago when he pulled together some interviews from scientists and wrote a nine-paragraph story about how the planet was getting cooler. This difference in orientation led to striking differences in insight. Japanese primatologists discovered that male rank was only one factor determining social relationships and group composition.
