Discovery makes microscopic imaging possible in dark conditions

Researchers have discovered a new way to more accurately analyze microscopic samples by essentially making them 'glow in the dark', through the use of chemically luminescent molecules. Current methods of microscopic imaging rely on fluorescence, which means a light needs to be shining on the sample while it is being analyzed. While this method is effective, it also has some drawbacks.

Evolution makes the world less ragged

How does evolution impact ecological patterns? It helps smooth out the rough edges, say researchers. A new review of the history of ecological and evolutionary research establishes a framework to better understand evolution's impact on ecosystem patterns.

Study sheds light on how cancer spreads in blood

A new study sheds light on proteins in particles called extracellular vesicles, which are released by tumor cells into the bloodstream and promote the spread of cancer. The findings suggest how a blood test involving these vesicles might be used to diagnose cancer in the future, avoiding the need for invasive surgical biopsies.

Care for cats? So did people along the Silk Road more than 1,000 years ago

Common domestic cats, as we know them today, might have accompanied Kazakh pastoralists as pets more than 1,000 years ago. This is indicated by new analyses done on an almost complete cat skeleton found during an excavation along the former Silk Road in southern Kazakhstan. An international research team has reconstructed the cat's life, revealing astonishing insights into the relationship between...

Extreme rainfall events cause top-heavy aquatic food webs

Scientists across seven different sites throughout Central and South America replicated the extreme rainfall events predicted by climate change science. Using the insect larvae that live in the water trapped by bromeliad plants as a model ecosystem, they found that food webs became top-heavy with predators when there were large day-to-day variations in rainfall.

The spin state story: Observation of the quantum spin liquid state in novel material

The quantum spin liquid (QSL) state is an exotic state of matter where the spin of electrons, which generally exhibits order at low temperatures, remains disordered. Now, scientists have developed a new material where a two-dimensional QSL state can be experimentally observed, advancing our knowledge of spin behavior, and getting us closer to next-generation ''spintronic'' devices.

Stress testing 'coral in a box'

Coral death is impacting oceans worldwide as a consequence of climate change. The concern is that corals cannot keep pace with the rate of ocean warming. In particular, because a temperature increase of only one degree Celsius can make the difference between healthy and dying coral reefs. Some corals, however, are more resistant to increasing temperatures. In order to effectively protect coral...

'Bystander Effect' not exclusive to humans

A rat is less likely to help a trapped companion if it is with other rats that aren't helping, according to new research that showed the social psychological theory of the ''bystander effect'' in humans is present in these long-tailed rodents.
