How our immune system detects broken DNA

Added: 20.11.2018 21:20 | 4 views | 0 comments

Our immune system can detect when our own cells are damaged. This DNA damage can come from a variety of sources, such as the sun's UV rays, chemical agents like cigarette smoke, or from genotoxic drugs used in chemotherapy. A new study found that DNA damage can lead to an immune response similar to that observed during viral infection.

For most people, a trip to the beach involves slathering on a thick layer of sunscreen to protect against sunburn and skin cancer. However, savvy beachgoers know to reapply sunscreen every few hours because it eventually washes off. Now researchers have detected high levels of sunscreen chemicals in the waters of Shenzhen, China, and they also show that the products can affect zebrafish embryo development.

Transforming carbon dioxide into industrial fuels

Added: 20.11.2018 17:58 | 2 views | 0 comments

One day in the not-too-distant future, the gases coming from power plants and heavy industry, rather than spewing into the atmosphere, could be captured and chemically transformed from greenhouse gases like carbon dioxide into industrial fuels or chemicals thanks to a new system that can use renewable electricity to reduce carbon dioxide into carbon monoxide -- a key commodity used in a number of industrial processes.

Powerful method probes small-molecule structures

Added: 20.11.2018 17:58 | 7 views | 0 comments

Small molecules -- from naturally occurring metabolites and hormones to synthetic medicines and pesticides -- can have big effects on living things. But for scientists to understand how the molecules work and how to design beneficial ones, they need to know the precise arrangement of atoms and chemical bonds. Now researchers have found a faster, simpler and potentially more reliable way to solve the structures of small molecules.

Chemistry freed from space and time

Added: 19.11.2018 23:18 | 11 views | 0 comments

Shopping on the internet, storing photos in the cloud, turning up a thermostat with an app -- all are commonplace. Now, the internet of things and the cloud are entering the world of chemical research and production. Researchers have used remote servers in Japan to autonomously optimize conditions to synthesize drugs in a British laboratory. The process was controlled over the internet by researchers in the USA.
