“Knowing what a chicken looks like and what all the chickens before it looked like doesn’t help us to understand the egg,” says Taras Gerya. The ETH Professor of Geophysics uses this metaphor to address plate tectonics and the early history of the Earth. The Earth’s lithosphere is divided into several plates that are in constant motion, and today’s geologists […]

Climate change may have helped to alter the course of history. A period of extreme and unprecedented cooling in the northern hemisphere 1,500 years ago may have reduced the eastern Roman empire, set the stage for a famine and a devastating pandemic that killed millions, and favored the rise of the Islamic forces that created the Arab empire. The so-called Little […]

Across the world, bats are in trouble from climate change – not only through collisions with the wind turbines that are intended to mitigate its effects, but from what the increasing warmth does to their ability to find their prey. Bats often get a bad press, portrayed as disease-spreading bloodsuckers. In fact, they perform a vital role as pollinators, seed […]

Sea ice is formed from ocean water that freezes. Because the oceans consist of saltwater, this occurs at about minus 1.8 degrees Celsius (28.8 degrees Fahrenheit). Most Antarctic sea ice occurs annually, meaning it forms in the winter and melts during the summer. Sea ice regulates exchanges of heat, moisture and salinity in the polar oceans. It insulates the relatively warm […]

Antarctica’s native insect, the Antarctic Midge is a flightless insect that can survive nine months frozen at temps of at least negative 15 degrees Celsius. It loses about 70% of its body fluids and can live for about a month without oxygen. The midge survives because of its combination of rapid cold hardening and warm temperatures in its underground habitat. […]

Astrobiologists searching the heavens for extraterrestrial life have a simple motto: “Follow the water, ”says The Washington Post. Water is an essential ingredient in all earthly biochemistry, so scientists believe it’s logical to look for life first on planets and moons with liquid water.New data from NASA’s Cassini spacecraft indicate that Enceladus, a tiny, ice-encrusted moon orbiting Saturn, may be […]

The amount of plastic garbage in the North Pacific Ocean has risen a hundredfold since the 1970s, and the floating debris is now so abundant that marine life is adapting to its presence. Researchers from the Scripps Institution of Oceanography sampled an expanse of the sea between Hawaii and California, where currents tend to deposit flotsam from around the Pacific […]

The key to helping animals evolve quickly in response to climate change could actually be their predators, according to a new UBC study. The study is one of the first to show that species interactions, meaning the way species interact with each other in an ecosystem, like in a predator-prey relationship, is important to understanding how animals will respond to […]
