Gene-editing: how it could be used in NZ

Kiwis are being urged to have their say on gene-editing technologies, as our leading body for science today sets out how they could be used to combat pests or replace faulty genes.

Gene editing has been at the centre of a fast-moving global revolution, fuelled by advances such as the CRISPR-Cas system that’s effectively given scientists “molecular scissors” to snip and splice DNA.

$242,000 to Tairāwhiti Community Group for Erosion Control

A Tairāwhiti group looking to optimise the sustainable growth and harvest of Kānuka is set to receive up to $242,000 from the Ministry for Primary Industries for its erosion control benefits.

Hikurangi Bioactives Limited Partnership, a majority community-owned charitable company, is looking to identify optimal growing and sustainable harvesting techniques for bioactive extracts from existing mature Kānuka strands grown in and around Ruatoria.

AgTech StartUp Uses Lasers To Improve Artificial Insemination In Dairy Cows

An AgTech startup in New Zealand, Engender Technologies has created a new microfluidic and photonic technology to sort livestock sperm by sex to enrich X chromosome-bearing bull sperm cells.

The new technology uses lasers to orient sperm cells and look inside those sperm cells as well as separate them based on the presence of an X or a Y chromosome.  In contrast to the industry’s standard practice of using an electric charge and field in the artificial insemination process, Engender’s technology uses a wavelength of light to sort cells-on-a-chip. The company believes this will reduce the negative impact on the fertility rate of sperm cells sorted through its system and give dairy farmers great control over offspring.

What happened when one expert killer was visited by the US military’s science agency

When Kiwi rat killing expert Doctor James Russell was told his research was being sized up for United States military funding, he wasn’t surprised.

“The US military – they have very long fingers. Even through the universities in New Zealand, they have a representative that comes around and just asks, ‘hey, what are you guys up to’.

“And obviously we’re in the business of eradicating entire populations of animals from an island and so they have cocked their ear towards me once or twice.

What is gene drive technology and what does it mean for New Zealand?

We’ve been hearing a lot about this technology over recent years – yet the concept has been about for half a century.

The concept of a synthetic gene drive was devised almost 50 years ago by Christopher Curtis who proposed rearranging genetic material to “drive” anti-pathogenic genes into wild species.

The idea was taken further by UK evolutionary geneticist Professor Austin Burtin, who discussed how a synthetic gene drive could be used to prevent insects spreading diseases such as malaria.

LCT files pericyte protective agent provisional patent


The invention in this provisional patent arises from LCT’s research collaboration with the Centre for Brain Research (CBR) at The University of Auckland. The research collaboration explored how LCT’s products can reverse human brain neurodegenerative processes associated with pericytes (and other brain cells), which help sustain the blood-brain barrier and other homeostatic and haemostatic functions in the brain.

2 new CRISPR tools overcome the scariest parts of gene editing

Several years ago, scientists discovered a technique known as CRISPR/Cas9, which allowed them to edit DNA more efficiently than ever before.

Since then, CRISPR science has exploded; it’s become one of the most exciting and fast-moving areas of research, transforming everything from medicine to agriculture and energy. In 2017 alone, more than 14,000 CRISPR studies were published.

New Zealand will get blindsided by artificial meat and milk

New Zealand will be left behind if the country doesn’t embrace the future of meat and milk, says columnist and former Federated Farmers Whanganui president Rachel Stewart.

“I think we’re going to get blindsided very soon, and Fonterra’s not really waking up to it,” Stewart said on Media Take on Tuesday.

“They were saying last week they don’t think [artificial meat and milk] is a threat – it’s a huge threat, it’s happening in India, it’s happening in California.

Dr Clyde Smith interviewed by Andrew Patterson

Follow the link to listen to Andrew Pattersons interview with Dr Clyde Smith starts at 22:30

Andrew’s feature guest this week is NZ born research scientist Dr Clyde Smith who has been based at Stanford in the US for the last decade.
They discuss the growing concern regarding antibiotic-resistant super-bugs and what is being termed the “research void” that has occurred where no significant scientific discoveries have been made in this area for more than two decades.
