Single Test for over 50 Genetic Diseases will cut Diagnosis from Decades to Days

Validating genetic diagnosis of neurological and neuromuscular diseases using faster, smaller, cheaper sequencing technologies. A new DNA test, developed by researchers at the Garvan Institute of Medical Research in Sydney and collaborators from Australia, UK and Israel, has been shown to identify a range of hard-to-diagnose neurological and neuromuscular genetic diseases quicker and more-accurately than existing tests.

‘We correctly diagnosed all patients with conditions that were already known, including Huntington’s disease, fragile X syndrome, hereditary cerebellar ataxias, myotonic dystrophies, myoclonic epilepsies, motor neuron disease and more,’ says Dr Ira Deveson, Head of Genomics Technologies at the Garvan Institute and senior author of the study.

The diseases covered ...

Scientists’ increasing mastery of quantum mechanics is heralding a new age of innovation. Technologies that harness the power of nature’s most minute scale show enormous potential across the scientific spectrum, from computers exponentially more powerful than today’s leading systems, sensors capable of detecting elusive dark matter, and a virtually unhackable quantum internet.

Researchers at the Department of Energy’s Oak Ridge National Laboratory, Freedom Photonics and Purdue University have made strides toward a fully quantum internet by designing and demonstrating the first ever Bell state analyzer for frequency bin coding.

Their findings were published in Optica.

Some Oral Bacteria linked with Hypertension in Older Women

In a study of more than 1,200 women in the U.S., average age 63 years, 10 kinds of oral bacteria were associated with a higher risk of developing high blood pressure, while five strains of bacteria were linked with lower hypertension risk. The observational study cannot prove cause and effect; however, the findings highlight possible opportunities to enhance hypertension prevention through targeted oral care, researchers said.

Some oral bacteria were associated with the development of hypertension, also known as high blood pressure, in postmenopausal women, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American H...

‘Drug factory’ Implants Eliminate Ovarian, Colorectal Cancer in Mice

Immunotherapy treatment could begin human clinical trials this year. Rice University bioengineers have shown they can eradicate advanced-stage ovarian and colorectal cancer in mice in as little as six days with a treatment that could be ready for human clinical trials later this year.

The researchers used implantable “drug factories” the size of a pinhead to deliver continuous, high doses of interleukin2, a natural compound that activates white blood cells to fight cancer...
