AI can help write a message to a friend -- but don't do it      (via sciencedaily.com) 

Using artificial intelligence applications to help craft a message to a friend is not a good idea -- at least if your friend finds out about the use of AI, a new study suggests.

Nutrients drive cellular reprogramming in the intestine      (via sciencedaily.com)     Original source 

Researchers have unveiled an intriguing phenomenon of cellular reprogramming in mature adult organs, shedding light on a novel mechanism of adaptive growth. The study, which was conducted on fruit flies (Drosophila), provides further insights into dedifferentiation -- where specialized cells that have specific functions transform into less specialized, undifferentiated cells like stem cells.

These worms have rhythm      (via sciencedaily.com)     Original source 

Researchers have developed a new imaging technique to observe active gene expression in real time. They found that four molecules work together to control the timing of each stage of the C. elegans worm's development. This timekeeping process could provide important clues about the natural rhythm of development in humans and other animals.

Online AI-based test for Parkinson's disease severity shows promising results      (via sciencedaily.com) 

A new artificial intelligence tool can help people with Parkinson's disease remotely assess the severity of their symptoms within minutes. While expert neurologists performed slightly better than the AI model, the AI model outperformed the primary care physicians with UPDRS certification.

Researchers grow embryonic humanized kidneys inside pigs for 28 days      (via sciencedaily.com)     Original source 

Researchers have successfully created chimeric embryos containing a combination of human and pig cells. When transferred into surrogate pig mothers, the developing humanized kidneys had normal structure and tubule formation after 28 days. This is the first time that scientists have been able to grow a solid humanized organ inside another species, though previous studies have used similar methods to generate human tissues such as blood or skeletal muscle in pigs.

Genetic tools probe microbial dark matter      (via sciencedaily.com)     Original source 

Genetic manipulation of a puzzling, miniscule bacteria that has lived in human mouths at least since the Middle Stone Age is elucidating the genes needed for its unusual lifestyle. These Patescibacteria in the human oral microbiome reside on the surface of another, larger host microbe. Found in many water and land environments, Patescibacteria in general lack the genes required to make many molecules necessary for life, such as the amino acids that make up proteins, the fatty acids that form membranes, and the nucleotides in DNA. This has led researchers to speculate that many of them rely on other bacteria to grow. In a new study, researchers present the first glimpse into the molecular mechanisms behind their relationship with their host cells. They also share details gleaned from fluorescent, time-lapse microsopic imaging of these bacteria as they bud and send out swarms of tiny progeny, only a fraction of which are able to establish a host relationship.

Study illuminates mechanism that annotates genetic information passed from fathers to offspring      (via sciencedaily.com)     Original source 

Scientists have identified a key part of a mechanism that annotates genetic information before it is passed from fathers to their offspring. The findings shed new light on genomic imprinting, a fundamental, biological process in which a gene from one parent is switched off while the copy from the other parent remains active. Errors in imprinting are linked to a host of diseases, such as the rare disease Silver-Russell syndrome along with certain cancers and diabetes.

Unveiling the mechanism of 3D folding of cell sheets      (via sciencedaily.com)     Original source 

A team of researchers has revealed that the Dumpy protein, a component of extracellular matrices -- or ECM -- is the key factor in regulating the stereotypic origami-like folding of wing-cell sheets. Their findings that wing cells never divide during folding nor do they exhibit spatially distinct behaviors suggest how external cues can create consistent 3D tissue structures.

Immune cells shape their own path      (via sciencedaily.com)     Original source 

When fighting disease, our immune cells need to reach their target quickly. Researchers have now discovered that immune cells actively generate their own guidance system to navigate through complex environments. This challenges earlier notions about these movements. The researchers' findings enhance our knowledge of the immune system and offer potential new approaches to improve human immune response.

New AI technology gives robot recognition skills a big lift      (via sciencedaily.com) 

The day when robots can cook dinner, clear the kitchen table and empty the dishwasher is still a long way off. First, robots need to be able to recognize the many items of different sizes, shapes and brands in our homes. A team has now made a significant advance toward that technology with a robotic system that uses artificial intelligence to help robots better identify and remember objects.

Analog and digital: The best of both worlds in one energy-efficient system      (via sciencedaily.com) 

We live in an analog world of continuous information flow that is both processed and stored by our brains at the same time, but our devices process information digitally in the form of discrete binary code, breaking the information into little bits (or bites). Researchers have revealed a pioneering technology that combines the potential of continuous analog processing with the precision of digital devices. By seamlessly integrating ultra-thin, two-dimensional semiconductors with ferroelectric materials, the research unveils a novel way to improve energy efficiency and add new functionalities in computing. The new configuration merges traditional digital logic with brain-like analog operations.
