Antibiotic resistance in spore-forming probiotic bacteria

New research has found that six probiotic Bacillus strains are resistant to several antibiotics. Genetic analysis of other Bacillus strains has shown genes that contribute to antibiotic resistance towards various types of drugs and methods in which they can still grow in their presence. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology.

Discovery of the cell fate switch from neurons to astrocytes in the developing brain

During mammalian brain development, neural precursor cells first generate neurons and later astrocytes. This cell fate change is a key process generating proper numbers of neurons and astrocytes. Here we discovered that FGF regulates the cell fate switch from neurons to astrocytes in the developing cerebral cortex using mice. FGF is a critical extracellular regulator of the cell fate switch, necessary and sufficient, in the mammalian cerebral cortex.

NASA helps warn of harmful algal blooms in lakes, reservoirs

Harmful algal blooms can cause big problems in coastal areas and lakes across the United States. When toxin-containing aquatic organisms multiply and form a bloom, it can sicken people and pets, contaminate drinking water, and force closures at boating and swimming sites.

Plants may be transmitting superbugs to people

Antibiotic-resistant infections are a threat to global public health, food safety and an economic burden. To prevent these infections, it is critical to understand how antibiotic-resistant bacteria and their genes are transmitted from both meat and plant-foods. Researchers have now shown how plant-foods serve as vehicles for transmitting antibiotic resistance to the gut microbiome. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology.

Researchers discover traditional fluid flow observations may miss the big picture

Before and after comparisons don't tell the full story of chemical reactions in flowing fluids, such as those in a chemical reactor, according to a new study from a collaboration based in Japan.

Bacteria live on our eyeballs—and understanding their role could help treat common eye diseases

You may be familiar with the idea that your gut and skin are home to a collection of microbes—fungi, bacteria and viruses—that are vital for keeping you healthy. But did you know that your eyes also host a unique menagerie of microbes? Together, they're called the eye microbiome. When these microbes are out of balance—too many or too few of certain types—eye diseases may emerge.

Artificial intelligence learns to recognize nerve cells by their appearance

Is it possible to understand the brain? Science is still far from answering this question. However, since researchers have started training artificial intelligence on neurobiological analyses, it seems at least possible to reconstruct the cellular structure of a brain. New artificial neural networks developed by the Max Planck Institute of Neurobiology and Google AI can now even recognize and classify nerve cells independently based on their appearance.

Major HIV drug requires vigilance, study says

A study lead by researchers at the Institute of HIV Research, Medical Faculty of UDE and University Hospital Essen reports a potential toxicity of integrase inhibitors. Integrase inhibitors (INSTI) are a preferred drug for inclusion in anti-retroviral therapy regimens given its tolerability, efficacy and high resistance barrier. INSTI have been found to improve and prolong lives of millions of people living with HIV who suffer side-effects and resistance to treatment. However, recent laboratory data suggest that INSTI may not be as safe as suggested.
