Polystyrene waste is everywhere, in foam packaging materials, disposable food containers, cutlery and many other applications and it’s not biodegradable. But scientists have just found a green, low-energy way to break it down.

A new report published in Proceedings of the National Academy of Sciences suggests older age and alcohol consumption in the year leading up to conception also may have an impact by epigenetically altering a specific gene during development of human eggs, or oocytes.

Rheumatoid arthritis is an autoimmune disease in which immune cells erroneously attack the body's own joint components and proteins, causing painful inflammation and even the destruction of bone. Scientists have now taken a step toward understanding and, potentially, treating rheumatoid arthritis better, with the identification of genes that were overexpressed in various mouse models of arthritis.

Researchers from the Qingdao Institute of BioEnergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have stripped hundred-kilobase genome from a type of oil-producing microalgae, knocking out genes non-essential for it to function. By doing so, they have created a "genome scalpel" that can trim microalgal genomes rapidly and creatively.

Scientists have established a link between poor semen quality in adult men and their mothers’ occupational exposure to endocrine disruptors during pregnancy.

Scientists have solved the mystery of how living organisms distinguish RNA and DNA building blocks during gene expression, paving the way for the design of new antiviral drugs.

Researchers have designed a new bioink that allows small human-sized airways to be 3D-bioprinted for the first time. The 3D-printed constructs are biocompatible and support new blood vessel growth into the transplanted material. This is an important first step towards 3D-printing organs.

Researchers have developed hybrid nanostructured particles that can be magnetically guided towards a tumor. They can also be tracked by their fluorescence and triggered to release the drug on demand using ultrasound.

Scientists have shown that by blocking "cell drinking", or macropinocytosis, in the tissue surrounding a pancreatic tumor, it is possible to slow the tumor's growth. This suggests that macropinocytosis could be exploited therapeutically.

A new study has found that, when inserted into mice, giraffe genes confer resistance to high blood pressure.
