Glyphosate, the primary ingredient in Monsanto’s popular weed killer Roundup, has been linked to liver disease in animal models. In a new study, the first of its kind, researchers at the University of California San Diego School of Medicine report an association between the herbicide and negative effects upon the human liver.

In a study published in Clinical Gastroenterology and Hepatology, a team led by Paul J. Mills, Ph.D., professor and chief in the Department of Family Medicine and Public Health at UC San Diego School of Medicine, examined glyphosate excretion in the urine samples of two patient groups—those with a diagnosis of NASH (non-alcoholic steatohepatitis, a type of nonalcoholic fatty liver disease or NAFLD), and those without. The results, they found, were significant: Regardless of age, race, body mass index (BMI), ethnicity or diabetes status, glyphosate residue was significantly higher in patients with NASH than it was in patients with a healthier liver.

The findings, coupled with prior animal studies, said Mills, suggest a link between the use of commercial glyphosate in our food supply, which has increased significantly over the past 25 years, and the prevalence of NAFLD in the United States, which too has been on the rise for two decades.

University of Sydney research provides new evidence that nanoparticles, which are present in many food items, may have a substantial and harmful influence on human health.

The study investigated the health impacts of food additive E171 (titanium dioxide nanoparticles) which is commonly used in high quantities in foods and some medicines as a whitening agent. Found in more than 900 food products such as chewing gum and mayonnaise, E171 is consumed in high proportion everyday by the general population.

Published in Frontiers in Nutrition, the mice study found that consumption of food containing E171 has an impact on the gut microbiota (defined by the trillions of bacteria that inhabit the gut) which could trigger diseases such as inflammatory bowel diseases and colorectal cancer.

Growing food without plants or animals sounds far-fetched. But it could stop environmental destruction, says Guardian columnist George Monbiot.

Huge plastic waste dumps float in the Oceans bigger than continents. Some 10% of world’s plastic waste finds its way into the sea and ends up in the central regions where slow moving circular currents trap debris into one large constantly moving mass of plastic. This is slowly being broken down into a plastic dust that marine wildlife mistake for food. Small fish consume tiny bits of plastic as if they were normal plankton. Those fish are then consumed by larger species and the plastic contamination moves up the food chain. Over a million seabirds, as well as more than 100 thousand marine mammals, die every year from ingesting plastic debris. Some researchers estimate that there are over six kilos of plastic for every kilo of naturally occurring plankton in the Pacific plastic waste dump.

Dead seabirds having mistaken plastics for food, have been found with discarded plastic lighters, water bottle caps and scraps of plastic bags in their stomachs. / Oceanic gyres: the circular movement of the ocean waters concentrates the plastic in the centre of the oceans.

But maybe things are not as bad as it looks: scientists working on the pollution saw that it did not grow in 22 years, even if the plastic production grew fourfold. An organism may be eating plastic in the ocean, but whether the bug is green or mean remains to be seen.

Agriculture is changing. This is who’s leading the charge.

Making sure astronauts on space missions have sufficient supplies is a major challenge. Not only does food need to be sent up to locations like the International Space Station (ISS) in expensive resupply launches, but a further problem is making sure that astronauts have enough water and oxygen for their needs as well.

It’s also hard to ensure that the astronauts are getting sufficient nutrition from their diet. Ideally the astronauts would be able to grow their own food on the space station, but plants react strangely to microgravity so it’s hard to grow fruits and vegetables successfully.

The current life support systems used in space use chemical reactions to create water and oxygen and to recycle carbon dioxide. But a new system could use algae to produce oxygen, water, and even food.

The concept of fate is often used in the context of love and choosing a partner. In your book, you talk about a study that give a scientific explanation for the idea that “opposites attract”. A panel of men was asked to wear a T-shirt for several nights and days and they weren’t allowed to wear deodorant or eat anything too smelly. The T-shirts were presented to an array of women who were asked to sniff then and rate them in terms of attractiveness based purely on smell. It turns out that the females rated the males as more attractive if their MHC [major histocompatibility complex] systems were different from their own, because then their offspring would have a stronger immune system, a better range of armoury against potential infections. So women were kind of sniffing out Mr Right.

What else does neuroscience tell us about a successful relationship? If you image the brains of the couples who have been together for a long, long time and ask them to think about their partner, their brain will react in the same way as a drug addict’s. You can almost say this couple are addicted to each other.

You say “affection is a neurochemical event” – that’s not very romantic. Valentine’s Day with me is a lot of fun!
