How much food can the world grow? International team calls for new yield potential estimates

Agronomists question statistical methods used to predict yield potential and 'yield gaps' for major crops. In some cases, yield potential is overestimated, while in others it can be underestimated. It's important to have accurate information so that worldwide agriculture can meet the food demands of the growing global population.

Sink or Swim: The fate of sinking tectonic plates depends on their ancient tectonic histories

New findings provide a greater understanding of plate subduction, or how tectonic plates slide beneath one another. This recycling of surface materials and volatile elements deep into the Earth's interior, can impact long-term climate stability, atmospheric balance, and the habitability of our planet over billions of years.

Starch-based microplastics could cause health risks in mice

Wear and tear on plastic products releases small to nearly invisible plastic particles, which could impact people's health when consumed or inhaled. To make these particles biodegradable, researchers created plastics from plant starch instead of petroleum. An initial study shows how animals consuming particles from this alternative material developed health problems such as liver damage and gut microbiome imbalances.

From bacterial immunity to plant sex

Could it be that one of only three known markers directly targeting the DNA does not exist outside the realm of microbes? Now, researchers have demonstrated that this marker -- N4-methylcytosine (4mC) -- is essential for sperm development and maturation in the liverwort Marchantia polymorpha, a key organism in plant evolution.

Engineering smart delivery for gene editors

A research team has developed an advanced delivery system that transports gene-editing tools based on the CRISPR/Cas9 gene-editing system into living cells with significantly greater efficiency than before. Their technology, ENVLPE, uses engineered non-infectious virus-like particles to precisely correct defective genes -- demonstrated successfully in living mouse models that are blind due to a mutation. This system also holds promise for advancing cancer therapy by enabling precise genetic manipulation of engineered immune cells making them more universally compatible and thus more accessible for a larger group of cancer patients.

'Sugar' signatures help identify and classify pancreatic cancer cell subtypes

Scientists have developed a new method for identifying and classifying pancreatic cancer cell subtypes based on sugars found on the outside of cancer cells. These sugars, called glycans, help cells recognize and communicate with each other. They also act as a cellular 'signature,' with each subtype of pancreatic cancer cell possessing a different composition of glycans.

Long-term health impacts of flooding revealed

A comprehensive study of the long-term health impacts of flooding -- via analysis of over 300 million hospitalizations records in eight countries prone to flooding events -- has found an increased risk of 26 per cent of all diseases serious enough to require hospitalization. This impact on the health of communities lasts up to seven months post event.
