Cancer cells 'remove blindfold' to spread

Cancer cells spread by switching on and off abilities to sense their surroundings, move, hide and grow new tumors, a new study has found.

Geoscientists use zircon to trace origin of Earth's continents

Geoscientists have long known that some parts of the continents formed in the Earth's deep past, but the speed in which land rose above global seas—and the exact shapes that land masses formed—have so far eluded experts.

New method sees fibers in 3-D, uses it to estimate conductivity

As a vehicle travels through space at hypersonic speeds, the gases surrounding it generate heat at dangerous temperatures for the pilot and instrumentation inside. Designing a vehicle that can drive the heat away requires ...

Tomato's wild ancestor is a genomic reservoir for plant breeders

Thousands of years ago, people in South America began domesticating Solanum pimpinellifolium, a weedy plant with small, intensely flavored fruit. Over time, the plant evolved into S. lycopersicum—the modern cultivated tomato.

Researchers offer new theory on 'Venus' figurines

One of world's earliest examples of art, the enigmatic 'Venus' figurines carved some 30,000 years ago, have intrigued and puzzled scientists for nearly two centuries. Now a researcher from the University of Colorado Anschutz ...

Drug reverses age-related cognitive decline within days

Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study by UC San Francisco scientists. The drug, called ISRIB, has already been shown in ...

Engineers combine light and sound to see underwater

Stanford University engineers have developed an airborne method for imaging underwater objects by combining light and sound to break through the seemingly impassable barrier at the interface of air and water.

European colonization accelerated erosion tenfold

Rates of soil erosion and alluvium accumulation in North America accelerated 10-fold after Europeans colonized the continent, according to new research carried out by scientists from China, Belgium and U.S..

Breaking the rules of chemistry unlocks new reaction

Scientists have broken the rules of enzyme engineering to unlock a new method for creating chemical reactions that could unlock a wide range of new applications—from creating new drugs to food production.

Examining climate effects of regional nuclear exchange

A team of Lawrence Livermore National Laboratory (LLNL) researchers has found that the global climatic consequences of a regional nuclear weapons exchange could range from a minimal impact to more significant cooling lasting ...

Mapping stellar nurseries in the Milky Way

An international team of Astronomers from the Cosmostatistics Initiative (COIN) identified nearly 120,000 new young stellar objects (YSOs) based on data from the Infrared Array Camera of NASA's Spitzer Space Telescope. ...

'Sabre-toothed tiger' skeleton up for auction

A nearly 40-million-year-old skeleton belonging to what is popularly called a sabre-toothed tiger is going under the hammer next week in Geneva, a year after its discovery on a US ranch.

Plants on aspirin

When pathogens enter a plant, infected cells set off an alarm before they die. They discharge methylsalicylic acid, which is later transformed into salicylic acid, triggering an immune response. Hence, salicylic acid is a ...

Climate change warms groundwater in Bavaria

Groundwater reservoirs in Bavaria have warmed considerably over the past few decades. A new study by researchers at Martin Luther University Halle-Wittenberg (MLU) compares temperatures at 35 measuring stations, taken at ...

Early human landscape modifications discovered in Amazonia

In 2002 Professor Alceu Ranzi (Federal University of Acre) and Prof. Martti Parssinen (University of Helsinki) decided to form an international research team to study large geometric earthworks, called geoglyphs, in the Brazilian ...

Watching the Arctic thaw in fast-forward

The Arctic is warming more quickly than almost any other region on Earth as a result of climate change. One of the better known: the continually shrinking summer sea-ice extent in the Arctic. But global warming is also leaving ...
