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.

Using game theory to model poisoning attack scenarios
Poisoning attacks are among the greatest security threats for machine learning (ML) models. In this type of attack, an adversary tries to control a fraction of the data used to train neural networks and injects malicious data points to hinder a model's performance.

B chromosome first—mechanisms behind the drive of B chromosomes uncovered
The specific number of chromosomes is one of the defining characteristics of a species. Whilst the common fruit fly carries 8 chromosomes, the genome of bread wheat counts 42 chromosomes. In comparison, the human genome is made out of a total of 46 chromosomes. However, about 15% of all eukaryotic species additionally carry supernumerary chromosomes referred to as "B chromosomes". Other than the essential chromosomes of the genome, B chromosomes are expendable and often preferentially inherited. This leads to a transmission advantage for B chromosomes called "chromosome drive". To date, little knowledge exists about the mechanisms behind this phenomenon. Researchers from the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) in Gatersleben have now been able to decipher the mechanisms behind the drive of B chromosomes in the goatgrass Aegilops speltoides. The novel insights in the workings of chromosome drive were recently published in New Phytologist.

A new drug target for chemically induced Parkinson's disease
More than three decades ago, scientists discovered that a chemical found in a synthetic opioid, MPTP, induced the onset of a form of Parkinson's disease. In a new study led by scientists from the School of Veterinary Medicine, researchers found that an enzyme in the body can metabolize compounds formed in the brain from alkaloids present in certain foods and tobacco into MPTP-like chemicals, triggering a neurodegenerative condition in mice.

NVIDIA going full stack for ARM boosts supercomputing presence
NVIDIA and ARM make one power couple for supercomputing. NVIDIA has announced its chips will work with ARM processors. Outside observers got busy earlier this week assessing why this was a big deal to empower both companies and the effort to explain was not at all difficult.

Researchers report the origin and immunoregulatory function of monocytes
Non-classical monocytes were long thought to play a purely surveillance role in the immune system. With the aid of a novel marker (PD-L1), Ludwig-Maximilians-Universitaet (LMU) researchers in Munich have now shown that they are directly involved in the regulation of immune response.

Applying active inference body perception to a humanoid robot
A key challenge for robotics researchers is developing systems that can interact with humans and their surrounding environment in situations that involve varying degrees of uncertainty. In fact, while humans can continuously learn from their experiences and perceive their body as a whole as they interact with the world, robots do not yet have these capabilities.
