Researchers said Wednesday they had observed water vapour escaping high up in the thin atmosphere of Mars, offering tantalising new clues as to whether the Red Planet could have once hosted life.

The traces of ancient valleys and river channels suggest liquid water once flowed across the surface of Mars. Today, the water is mostly locked up in the planet’s icecaps or buried underground.

But some of it is vaporising, in the form of hydrogen leaking from the atmosphere, according to the new r...

ProAgio, a drug developed by Georgia State University biology professor Zhi-Ren Liu and his team, is effective at treating pancreatic cancer and prolonging survival in mice, according to a study published in the journal Cellular and Molecular Gastroenterology and Hepatology.

A second study, published in the Journal of Experimental Medicine, shows the drug is also effective against triple-negative breast cancer, a fast-growing and hard-to-treat type of breast cancer that carries a poor prognosis.

ProAgio, created from a human protein, targets the cell surface receptor  integrin α_vβ₃ which is expressed on cancer-associated fibroblasts...

Emerging robotics technology may soon help construction companies and contractors create buildings in less time at higher quality and at lower costs.

Purdue University innovators developed and are testing a novel construction robotic system that uses an innovative mechanical design with advances in computer vision sensing technology to work in a construction setting.

The technology was developed with support from the National Science Foundation.

“Our work helps to address workforce shortages in the construction industry by automating key construction operations...

With the help of the international Gemini Observatory, a Program of NSF’s NOIRLab, and other ground-based telescopes, astronomers have confirmed that a faint object discovered in 2018 and nicknamed “Farfarout” is indeed the most distant object yet found in our Solar System. The object has just received its designation from the International Astronomical Union.

Farfarout was first spotted in January 2018 by the Subaru Tel...
