Current chemotherapy regimens slow cancer progression and save lives, but these powerful drugs affect both healthy and cancerous cells. Now, researchers reporting in ACS’ Nano Letters have designed DNA-based nanogels that only break down and release their chemotherapeutic contents within cancer cells, minimizing the impacts on normal ones and potentially eliminating painful and uncomfortable side effects.

Once ingested or injected, chemotherapy medications move throughout the body, indiscriminately affecting healthy cells along with those that are responsible for disease...

Soil microbial fuel cells proven to be capable of creating energy to filter a person’s daily drinking water in Brazil test. Engineers at the University of Bath have shown that it’s possible to capture and use energy created by the natural reactions occurring in microorganisms within soil.

A team of chemical and electrical engineers has demonstrated the potential of cheap, simple ‘soil microbial fuel cells’ (SMFCs), buried in the earth to power an electrochemical reactor that purifies water.

The proof-of-concept design was demonstrated during field testing in North-East Brazil that took place in 2019 and showed that SMFCs can purify about three litres of water...

Perovskites show potential for valleytronics applications. Engineers at Rice University and Texas A&M University have found a 2D material that could make computers faster and more energy-efficient.

Their material is a derivative of perovskite — a crystal with a distinctive structure — that has the surprising ability to enable the valleytronics phenomenon touted as a possible platform for information processing and storage.

The lab of materials scientist Jun Lou of Rice’s Brow...

Using telescopes from the European Southern Observatory (ESO) and other organisations around the world, astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole...
