Germany saw its highest temperature ever recorded Friday at 41.3°C (106.3°F), according to preliminary weather service data, as the country braces for the possibility of even higher temperatures over the weekend.
A large asteroid will zip past Earth this weekend, but don't worry: It poses no danger.
Our solar system is a celestial shooting gallery, chock-full of flying projectiles that one day could threaten Earth—so what can we do about it?
In a Penn State lab, a small cylinder of soil sits wired with sensors, slowly cooling as it mimics conditions thousands of miles away.

Scientists have spotted two humpback whales that made separate, record-breaking crossings between Australia and Brazil.
In Estonian schools, social studies classes provide a thorough education on what democracy is and what it means to be a citizen. However, knowledge alone is not enough to foster active citizenship or reduce the differences in civic skills between Estonian- and Russian-speaking
Governments, corporations and other institutions must all play constructive roles in mitigating the impacts of climate change. Universities, too, can and must help with that effort.
Investigative interviewing—the process of obtaining accurate and complete accounts from victims, witnesses and suspects—is the lifeblood of the criminal justice system.
The Botanical Garden in Uppsala was recently visited by animal ecology researchers, who conducted a BioBlitz to find, identify and record as many insects as possible in the Botanical Garden. One of the finds was an endangered butterfly called the Small Blue, Cupido minimus. It
Uranus and Neptune remain two of the most mysterious objects in the solar system, primarily because they have been visited only by NASA's Voyager 2 spacecraft in 1986 and 1989, respectively. Their "ice giant" moniker comes from longstanding hypotheses that their interiors are
