The discovery of a new compound by Michigan State University researchers could lead to improved chemotherapy treatments for different types of cancers – potentially with fewer side effects.
The discovery of the compound – known as SP-4-84 – was made by an MSU team led by Jetze Tepe, an assistant professor of chemistry, and is detailed in the December issue of the journal Chemistry & Biology. The researchers believe that the compound, when used in conjunction with chemotherapy drugs such as cisplatin and camptothecin, can make the anti-cancer drugs much more effective. “This may potentially mean that one could use less than one-tenth of the current drug dosage and still get the same therapeutic results – but fewer side effects – or use the same drug dosage which is now much more effective in its treatment,” Tepe said.
Even though this new compound is in the earliest stage of development, this is potentially good news for the millions of Americans diagnosed with cancer every year. The national Centers for Disease Control and Prevention says more than a half-million Americans die of cancer every year, second only to heart disease. Here is how the newly discovered compound works: Most anti-cancer drugs work by causing cell damage, such as DNA damage, which ultimately kills the cancer cells. However, cancer cells are also prone to repair themselves and survive the damage done by drugs, which renders the drugs less effective.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
