More than 20 years after NASA's Spirit rover landed on Mars, a researcher from Edith Cowan University (ECU) has uncovered new evidence that suggests water may once have covered large parts of the red planet.

While headlines warn that AI could unleash future biological threats, the technology also offers our best defense: a way to anticipate viral evolution and stress-test treatments. Rather than waiting for SARS-CoV-2 to mutate ...

New research from the University of Sussex has revealed the biological limits to human compassion and empathy. The study found a stark contrast between how the brain processes information about risk to human lives and information ...

Every cell carefully builds and positions thousands of proteins that allow it to sense and respond to its surroundings. Even small changes to these proteins often determine whether they work properly or are destroyed before ...

Imagine a smart bandage that could continuously monitor an infected wound, alerting doctors when bacteria spread or when treatment begins to work. That vision is one step closer to reality with new research from Virginia ...

Nanoporous material-based separation technology is vital in many applications because it can precisely distinguish between and separate nearly identical chemical or biochemical molecules.

Cancer cells survive by hiding from the immune system's surveillance. A KAIST research team has developed a new anticancer platform that makes cancer cells send out their own danger signals—prompting immune cells to attack—while ...

As water shot into an open stock tank atop a high-country mesa, a trickle soaked the dusty earth below. Scott Snyder rose from the shade to fasten a hose and stop the spillage.

To explain the stock market's reaction to earnings results, investors and other market participants have used a standard tool for decades: the earnings surprise.

Researchers have developed a low-cost, semi-automated, AI-driven method that uses remote cameras to survey bumblebees and potentially other insects. The new tool could have important implications for efforts to conserve declining ...

Nanocarbons are molecular-scale carbon structures considered to be the building blocks for next-generation materials. Until now, scientists have built them by fusing small, flat carbon molecules together at their edges. Modifying ...

Ancient footprints preserved along the shores of Kenya's Lake Turkana are reshaping scientists' understanding of one of humanity's extinct relatives. A paper published in Proceedings of the National Academy of Sciences describes ...
