How global warming might affect food security – The Hindu

Between the year 1870 (the first industrial revolution) and today, the global temperature has risen by almost 2 degrees Celsius. This has come about due to more fossil burning (oil, natural gas, coal), which has also increased the carbon dioxide…

Those funky cheese smells allow microbes to ‘talk’ to and feed each other

Researchers found that bacteria essential to ripening cheese can sense and respond to compounds produced by fungi in the rind and released into the air, enhancing the growth of some species of bacteria over others. The make-up of the cheese microbiome is critical to flavor and quality of the cheese.

Fats fighting back against bacteria

With antibiotic-resistant superbugs on the rise, this research shows a new way that cells are using to protect themselves – using fats as a covert weapon, and giving us new insights into alternative ways to fight infection.

Machine learning uncovers potential new TB drugs

Using a machine-learning approach that incorporates uncertainty, researchers identified several promising compounds that target a protein required for the survival of the bacteria that cause tuberculosis.

‘Honey bee, it’s me’

Honey bees rely on chemical cues related to their shared gut microbial communities, instead of genetic relatedness, to identify members of their colony. This new work is significant in part because it shows an integral role for the microbiome in the essential, everyday social interactions of honey bees, the Earth’s most important pollinators, researchers said.

World first study shows that some microorganisms can bend the rules of evolution

The dominant thinking in evolution focuses on inheritance between parent and offspring – or ‘vertical gene transfer (VGT)’. But now scientists are paying more attention to ‘horizontal gene transfer (HGT)’: the transmission of DNA other than from parent to offspring, as this transfer can tell us about the evolution of a number of other organisms such as bacteria. It can also help us to better understand antibiotic resistance.
