Solution to 50-year-old mystery could lead to gene therapy for common blood disorders - News

Jean Balchin Apr 06, 2018

In a recent study published in the journal Nature Genetics, UNSW Sydney-led researchers have used CRISPR-gene editing to introduce beneficial natural mutations into blood cells to boost their production of foetal haemoglobin. This study solves a 50-year-old mystery about how these mutations operate and alter the expression of human genes. Naturally carried by a small percentage of people, these mutations contribute to … Read More

Proteins- not just a food group - News

Jack Auty Mar 27, 2018

  Research that focuses on the fundamental, nitty gritty, seemingly inapplicable, minutia of the world is not very appealing or engaging, and on the surface seems like a waste of taxpayer money. But fundamental research is essential,  underfunded and hugely important. You can only build a beautiful building on solid foundations but unfortunately very few people care about what is … Read More

Deep water corals glow in the dark to survive - News

Jean Balchin Jul 05, 2017

It has long been established that corals in shallow waters glow because of fluorescent proteins that act as sunblock, protecting the endangered species from the sun’s intense rays. As any kiwi can attest, too much sunlight is bad for humans. Excess sunlight is also detrimental to corals. Some shallow water corals produce fluorescent proteins to block excessive sunlight that could … Read More

Sunday video: tackling Tuberculosis and biophysics - Code for life

Grant Jacobs Aug 25, 2013

This free-wheeling discussion between Science Alert’s Fiona McDonald and Vic Arcus (University of Waikato) and Greg Cook (University of Otago), with questions from the on-line audience, might give readers some a feel for the time and some of the factors involved in tackling a drug targeting effort, in this case for tuberculosis. It also offers … Read More

Loops to tie a knot in proteins? - Code for life

Grant Jacobs Jul 30, 2010

Most proteins fold onto themselves without forming knots. A minority form a ’topologically entangled conformation’, a knot. Proteins are strings of amino acids, chained together one after the other. (Source: WIkimedia Commons.) The properties of proteins depends on their specific three-dimensional fold, how the chain of amino acids are arranged in … Read More

The ribo what? - Labrinth

Vic Arcus Nov 17, 2009

In the cellular city, there is one factory which reigns supreme and it is called the ribosome. This is the molecular factory which produces proteins. It is a monolithic molecular complex which literally “translates” the information in genes (encoded by sequences of DNA and RNA) into proteins. It is also very ancient and is found in all forms of life … Read More
