Scientists glimpse signs of a Puzzling State of Matter in a Superconductor

SLAC scientists used an improved X-ray technique to explore exotic states of matter in an unconventional superconductor that conducts electricity with 100% efficiency at relatively high temperatures. They glimpsed the signature of a state known as pair density waves (PDW), and confirmed that it intertwines with another phase known as charge density wave (CDW) stripes – wavelike patterns of higher and lower electron density in the material. CDWs, in turn, are created when spin density waves (SDWs) emerge and intertwine. (Jun-Sik Lee/SLAC National Accelerator Laboratory)

Known as ‘pair-density waves,’ it may be key to understanding how superconductivity can exist at relatively high temperatures...

Bypassing Broken Genes

New approach to gene therapy can correct any disease-causing mutation within a gene. A new approach to gene editing using the CRISPR/ Cas9 system bypasses disease-causing mutations in a gene, enabling treatment of genetic diseases linked to a single gene, such as cystic fibrosis, certain types of sickle cell anemia, and other rare diseases. The method, developed and tested in mice and human tissue cultures by researchers at Penn State, involves inserting a new, fully functional copy of the gene that displaces the mutated gene.

A proof-of-concept for the approach is described in a paper appearing online April 20 in the journal Molecular Therapy.

The CRISPR/Cas9 system has allowed promising new gene therapies that can target and correct disease-causing mutations in a gene...

Review summarizes known links between Endocrine Disruptors and Breast Cancer Risk

Exposure to certain endocrine-disrupting chemicals could elevate the risk of breast cancer, according to a new comprehensive systematic review of epidemiological research. However, for many chemicals, evidence is inconsistent or still limited. The review was carried out by researchers at the universities of Hong Kong and Eastern Finland and published in Critical Reviews in Food Science and Nutrition.

Endocrine-disrupting chemicals (EDCs) can interfere with the body’s hormonal system, also called the endocrine system, and are widely present in the environment. They originate from a variety of sources, including pesticides, plasticisers and other industrial and pharmaceutical chemicals, as well as natural sources...

‘Undruggable’ Cancer Protein becomes druggable, thanks to Shrub

A chemist from Purdue University has found a way to synthesize a compound to fight a previously “undruggable” cancer protein with benefits across a myriad of cancer types.

Inspired by a rare compound found in a shrub native to North America, Mingji Dai, professor of chemistry and a scientist at the Purdue University Center for Cancer Research, studied the compound and discovered a cost-effective and efficient way to synthesize it in the lab...
