An international team of cancer researchers has developed a new type of copper-based nanoparticle that can kill tumor cells in mice. While the technology showed effectiveness on its own, by combining it with immunotherapy the scientists say it produced long-lasting effects, quickly killing off any cancer cells that dared to return.

The therapy centers on new knowledge around tumors’ aversion to certain types of nanoparticles. The research team made up of scientists from KU Leuven, the University of Bremen, the Leibniz Institute of Materials Engineering, and the University of Ioannina, discovered that tumor cells were particularly sensitive to nanoparticles made from copper and oxygen.

Once these copper oxide nanoparticles enter a living organism they dissolve and become toxic, killing off cancer cells that happen to be in the area. Key to the new nanoparticle design was the addition of iron oxide, which the researchers say enables it to kill off cancer cells while leaving healthy cells intact.

A long-sought-after class of “superdiamond” carbon-based materials with tunable mechanical and electronic properties was predicted and synthesized by Carnegie’s Li Zhu and Timothy Strobel. Their work is published by Science Advances.

Carbon is the fourth-most–abundant element in the universe and is fundamental to life as we know it. It is unrivaled in its ability to form stable structures, both alone and with other elements.

A material’s properties are determined by how its atoms are bonded and the structural arrangements that these bonds create. For carbon-based materials, the type of bonding makes the difference between the hardness of diamond, which has three-dimensional “sp3” bonds, and the softness of graphite, which has two-dimensional “sp2” bonds, for example.

Threats of cyber attacks on North America’s electric network systems are growing, industrial cybersecurity firm Dragos said in a new report this week.

This year, the firm has identified two groups, Magnallium and Xenotime, which are increasingly probing to compromise electric assets in North America, expanding their targeting from the oil and gas sector to include electric assets.

“This underscores the trend in threats expanding from single-vertical ICS operations to multi-vertical ICS operations we observe from adversaries targeting industrial entities,” Dragos said in its report.

An innovation may lead to lifelike evolving machines.

Stellar black holes form when massive stars end their life in a dramatic collapse. Observations have shown that stellar black holes typically have masses of about ten times that of the Sun, in accordance with the theory of stellar evolution. Recently, a Chinese team of astronomers claimed to have discovered a black hole as massive as 70 solar masses, which, if confirmed, would severely challenge the current view of stellar evolution. The publication immediately triggered theoretical investigations as well as additional observations by other astrophysicists.

Among those to take a closer look at the object was a team of astronomers from the Universities of Erlangen-Nürnberg and Potsdam. They discovered that it may not necessarily be a black hole at all, but possibly a massive neutron star or even an ‘ordinary’ star. Their results have now been published as a highlight-paper in the renowned journal Astronomy & Astrophysics.
