In a research breakthrough funded by NASA, scientists have synthesized a molecular system that, like DNA, can store and transmit information. This unprecedented feat suggests there could be an alternative to DNA-based life, ...
Dutch scientists have developed an instrument capable of detecting the presence of living plants kilometres away. In future, the technique could be used in the search for extraterrestrial life. The biologist Lucas Patty will ...
Just like the mythical creation stories that depict the formation of the world as the story of order from chaos, the early Earth was home to a chaotic clutter of organic molecules from which, somehow, more complex biological ...
Is there life beyond Earth?
Everything around you – your desk, your laptop, your coffee cup – in fact, even you – is made of stardust, the stuff forged in the fiery furnaces of stars that died before our sun was born. Probing the space surrounding ...
About 2.6 million years ago, an oddly bright light arrived in the prehistoric sky and lingered there for weeks or months. It was a supernova some 150 light years away from Earth. Within a few hundred years, long after the ...
An international team of astronomers using a combination of ground and space-based telescopes have reported more than 100 extrasolar planets in only three months. These planets are quite diverse and are expected to play a ...
In 2020, NASA's next rover will launch from Cape Canaveral Air Force Station in Florida and head to the Jezero Crater on Mars. Jezero was once home to an ancient lake-delta system that scientists believe may have captured ...
Not all stars are like the sun, so not all planetary systems can be studied with the same expectations. New research from a University of Washington-led team of astronomers gives updated climate models for the seven planets ...
Resonating oscillations of a planet's atmosphere caused by gravitational tides and heating from its star could prevent a planet's rotation from steadily slowing over time, according to new research by Caleb Scharf, who is ...
Evidence that catastrophic geological events could have created evolutionary bottlenecks that changed the course of life on Earth may be buried within ancient rocks beneath our feet.

Solar energy is one of the most promising resources to help reduce fossil fuel consumption and mitigate greenhouse gas emissions to power a sustainable future. Devices presently in use to convert solar energy into thermal ...
Many species of termites, whose societies are built on hierarchies of kings, queens, workers, and soldiers, live in towering nests that are ventilated by a complex system of tunnels.
Physicists at the University of Maryland have developed a powerful new method to detect radioactive material. By using an infrared laser beam to induce a phenomenon known as an electron avalanche breakdown near the material, ...
Organic electronics have the potential to revolutionize technology with their high cost-efficiency and versatility compared with more commonly used inorganic electronics. For example, their flexibility could allow companies ...
The light scattered by plasmonic nanoparticles is useful, but some of it gets lost at the surface and scientists are now starting to figure out why.
Human appetites are pushing makos and other iconic sharks to the brink of extinction, scientists warned in a new assessment of the apex predator's conservation status.
New research from Washington University in St. Louis explains the cellular processes that allow a sun-loving microbe to "eat" electricity—transferring electrons to fix carbon dioxide to fuel its growth.
Understanding how chemical reactions happen on tiny crystals in liquid solutions is central to a variety of fields, including materials synthesis and heterogeneous catalysis, but obtaining such an understanding requires that ...
The Trump administration's reliance on industry-funded environmental specialists is again coming under fire, this time by researchers who say that Louis Anthony "Tony" Cox Jr., who leads a key Environmental Protection Agency ...
University of Alberta paleontologists have just reported the world's biggest Tyrannosaurus rex and the largest dinosaur skeleton ever found in Canada. The 13-metre-long T. rex, nicknamed "Scotty," lived in prehistoric Saskatchewan ...
On Dec. 18, 2018, a large "fireball—the term used for exceptionally bright meteors that are visible over a wide area—exploded about 16 miles (26 kilometers) above the Bering Sea. The explosion unleashed an estimated 173 ...
Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving events. Although much calving ...
A team of researchers from Northwest University and Guizhou University, both in China and one from the U.S., has found and partially excavated a new treasure trove of marine fossils from the "Cambrian explosion" in southern ...
Did you know that music and diagnostic imaging have something in common? Sounds have a lower or higher pitch depending on the size of the object that creates them. Tubas and double basses are big and produce deep low-pitch ...
The string of volcanoes in the Cascades Arc, ranging from California's Mt. Lassen in the south to Washington's Mt. Baker in the north, have been studied by geologists and volcanologists for over a century. Spurred on by spectacular ...
Warmer temperatures are having a ripple effect on food webs in Ontario lakes, according to a new University of Guelph study.

Changing batteries in orbit took some huffing and puffing and some intricate maneuvering by two spacewalkers Friday. But in the end, it went almost as smoothly as doing the chore back on Earth.
It's a popular phrase used to describe people, things, and ideas that just don't mix—"like oil and water." Except it's not entirely true. Oil and water can mix, and can be very difficult to completely separate when brought ...
Striking traits seen only in males of some species – such as colourful peacock feathers or butterfly wings – are partly explained by gene behaviour, research suggests.
Related individuals of a soil bacterial species live in cooperative groups and exhibit astonishing genetic and behavioural diversity. ETH researchers recently published these findings in Science .
With natural gas booming across the Front Range, drilling rigs may operate within feet from cattle farms. That shared land use can confound attempts to understand trends in methane, a greenhouse gas and air pollutant—the ...
