A succession of sick pigs?

May 2018

In a re-run of the GM wonder-crop revolution which promised weed-free fields growing pest-free crops, it looks like we're getting a GM wonder-pig revolution of disease-free herds (soon to be followed by flocks of GM wonder-hens and shoals of GM wonder-fish).

Scottish scientists have modified pig genes to "massively increase resistance and resilience to infection". The first targets are 'Porcine Reproductive and Respiratory Syndrome Virus' (PRRSV) which causes breathing problems and leads to still births and stunted offspring when sows are infected, and African Swine fever.

A beer-like beverage

May 2018

Craft beer brewing is an art form whose products are fast gaining in popularity. Typically, a craft brew is tastier than industrial versions because it uses far more hop flowers whose complex essential oils impart the characteristic beer flavour and aroma.

The variability of hop flowers make them an irritation to big brewers because their market demands uniformity, their factories demand recipes, and art is beyond them. Hops are also expensive. But the other vital beer-ingredient, yeast, is cheap.

Food lesson for the future

May 2018

What's going to happen when the long-term consumption of GM foods takes its toll on our health?

If we're lucky, medics will notice a spike in some chronic disease, and toxicologists will manage to link the problem to GM elements in our diet. And then what? Will the novel culprit be withdrawn from sale?

Real-life infant harm from Glyphosate

May 2018
Glyphosate is the most heavily used herbicide worldwide. Where high-tech monoculture is the agricultural norm, GM glyphosate-tolerant crops account for huge and widespread use of this one herbicide.

In Argentina, for example, 65% of pesticides used are glyphosate-based. In the American mid-west, over 90% of the millions of acres of corn, soya and canola, are GM and glyphosate-tolerant.

After starting its commercial life with a 'safe as salt' ticket [1], long before modern sub-cellular and molecular safety tests had been developed, glyphosate has certainly become "one of the world's most studied chemicals" (President of The Agribusiness Council of Indiana). However, its real-life complexity is only now being recognised by scientists.

Glyphosate and AMPA in the air

GM crops are still hanging on to their 'environmentally-friendly' image.

Resistance to glyphosate-based herbicides is a feature of most GM crops. This GM trait enables soil-preserving no-till farming, and provides easy weed control with a single chemical reputed to be toxic only to weeds and to disappear readily from the environment. All this, plus glyphosate's early 'safe-as-salt' tag for humans [1] provided little incentive for scientific study of side-effects of the herbicide during the past decades of increasing use.

However, things are changing since the International Agency for Research on Cancer came to the conclusion that glyphosate is 'probably carcinogenic to humans' [2]. Questions are gradually surfacing about where glyphosate actually goes when it 'disappears' from the environment.

The emerging answers don't paint a comforting picture.

Who's stirring the GMO pot?

May 2018

Would you believe that, after decades of blaming the pesky Greens for stirring up consumer resistance to GM foods, US scientists have worked out that it's really the pesky Reds!

With state funding, the researchers tried to get a better understanding of the GM food controversy, the hope being that they could "put information out there to make people better understand GMOs ... then that fear (of GMOs) might go away". To this end, professors of sociology and agronomy in Iowa State University joined forces to look at how the media portrayed biotechnology to the public.

If this smells like a grand plan to counter the increasing US public scepticism about GM and all things connected to it, read on and decide for yourself.
