Scientists discover how essential methane catalyst is made
New ways to convert carbon dioxide (CO2) into methane gas for energy use are a step closer after scientists discovered how bacteria make a component that facilitates the process. Recycling CO2 into energy has immense potential for making these emissions useful rather than a major factor in global warming. However, because the bacteria that can convert CO2 into methane, methanogens, are notoriously difficult to grow, their use in gas production remains limited.

Antimicrobial substances identified in Komodo dragon blood
In a land where survival is precarious, Komodo dragons thrive despite being exposed to scads of bacteria that would kill less hardy creatures. Now in a study, scientists report that they have detected antimicrobial protein fragments in the lizard's blood that appear to help them resist deadly infections. The discovery could lead to the development of new drugs capable of combating bacteria that have become resistant to antibiotics.

Hybrid plant breeding: Secrets behind haploid inducers, a powerful tool in maize breeding
A common strategy to create high-yielding plants is hybrid breeding. However, getting the inbred lines in the first place can be a hassle. In maize, the use of so-called 'haploid inducers' provides a short cut to this cumbersome procedure, allowing to produce inbred lines in just one generation. A study now sheds light on the genetics behind haploid induction.

'Smart' bacteria remodel their genes to infect our intestines
Researchers have described how infectious bacteria can sense they’re attached to our intestinal cells, and then remodel their expression of specific genes, including those involved in virulence and metabolism, to exploit our cells and colonize our gut.

Unlocking the heart-protective benefits of soy
A product of digesting a micronutrient found in soy may hold the key to why some people seem to derive a heart-protective benefit from eating soy foods, while others do not.

Cat ownership not linked to mental health problems
New research has found no link between cat ownership and psychotic symptoms, casting doubt on previous suggestions that people who grew up with cats are at higher risk of mental illness.

T-cells support long-lived antibody-producing cells, team finds
A group of researchers has come to a better understanding of how long-lived, antibody-producing plasma cells are maintained.

Microbe, virus co-evolution: Model of CRISPR, phage co-evolution explains confusing experimental results
A new study suggests that researchers planning to use the CRISPR genome-editing system to produce designer gut bacteria may need to account for the dynamic evolution of the microbial immune system.
