It can't be heard, but different parts of the human body are in constant conversation, communicating to keep the entire system running efficiently. For biologists, being able to listen in on this discussion is a long-sought-after goal. Over the years, researchers have caught snippets of these exchanges, but the complete dialogue has remained out of reach.

New research from Indiana University has uncovered a previously unknown vulnerability in how bacteria build the whip-like tails they use to move. The researchers found that building these tails can put stress on the protective wall surrounding a bacterial cell and uncovered systems bacteria use to keep that stress from becoming destructive.

A new study has demonstrated that regional microbial imprints can remain detectable under commercial winemaking conditions. The research, appearing in Applied and Environmental Microbiology, shows that inoculated fermentations do not "override" native microbial diversity and that vineyard management and environmental conditions affect wine quality. The study helps explain why wines from different regions taste distinct even when made with similar techniques and supports regional flavors and branding.

A bacterial molecule called gladiolin can disarm invasive Candida albicans and strengthen the effects of a major antifungal drug. Candida albicans usually lives harmlessly in the human body, but under the wrong conditions it can transform into an invasive form capable of damaging tissue and causing life-threatening infection. Researchers from Monash University and the University [...]

That’s now just 1 billion years for all the apparatus to hit on the lucky combination randomly, unless we start with design principles.

A book sits atop a table. Although it's closed, its title, "Encyclopedia of Human Tissue," promises untold secrets. Perhaps with this book, you can learn about different cell types and what they look like under normal conditions or conditions of disease. Maybe you can learn how gene expression differs in the cells of younger and older people, or whether different patients' cells respond differently to the same treatments.

A genetically engineered bacterium can rapidly break down one of Earth's most abundant minerals, opening a promising new pathway for simultaneously removing carbon dioxide from the atmosphere and recovering critical elements used in electric vehicle batteries, according to new Cornell research.

Epithelial cells are the tiny shields that line and protect our bodies. In a developing embryo, epithelial cells grow, divide and move into positions to form the outer layers of our skin and the surfaces of our organs and blood vessels. When we scrape our skin, suffer an internal tear or undergo surgery, epithelial cells migrate to the site of injury to heal a wound. And when epithelial cells go haywire, they can turn malignant and spread through the body as cancer.

Baker's yeast is one of biotechnology's most important microorganisms. It has long been used to leaven bread and ferment beer. More recently, advances in synthetic biology have enabled engineered yeast to convert sugar into a wide range of products, including medicines, fuels and industrial chemicals. Yet even well-engineered yeast cells can be difficult to control in a precise and timely way.

Every living cell, from the simplest bacterium to a human neuron, relies on the same basic machinery to read, interpret, and use its DNA. This molecular machinery is so fundamental that life as we know it cannot exist without it. And because it is so essential, it has long been a target for drugs; it shuts down a bacterium's ability to access its own genes and it quickly dies.

The global expansion of chicken farming has created conditions that allow Campylobacter to spread, mix and adapt more readily. Commercial poultry farms now hold billions of chickens, creating a vast habitat where bacteria can move, mix and adapt. An analysis from the Ineos Oxford Institute for Antimicrobial Research at the University of Oxford found that [...]

Photosynthetic microorganisms can use light energy to convert carbon dioxide into useful compounds under mild, environmentally compatible conditions. However, many current photosynthetic production systems rely on cells growing freely in large volumes of liquid. This creates a substantial demand for water and requires extensive mixing to keep the cells evenly distributed and exposed to light, increasing the resource and energy requirements of the process.

For most healthy people, Cryptococcus is an unnoticed infection. The immune system walls it off in the lungs and keeps it dormant for life. But in patients undergoing cancer chemotherapy, recovering from an organ transplant, living with HIV or taking newer immunosuppressing drugs for autoimmune disease, the fungus can reactivate, spread to the brain and cause meningitis.

Researchers led by Sa Kan Yoo at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have discovered that the natural turnover of gut cells in fruit flies depends on how much food the flies get, rather than on any specific nutrient. They found that gut cells were replaced more frequently when nutrient levels were low and the insides of gut cells were fluid and watery.

Scientists trained artificial intelligence on libraries of DNA and then asked the model to create recipes for viral genomes. Sixteen of them were viable, yielding new viruses.

Researchers say breakthrough offers hope for new medicines but also raises urgent biosecurity questions

Scientists have made the first viruses designed by artificial intelligence in a milestone that raises hopes for new medicines but also concerns over how to ensure the technology remains safe.

The viruses are specific kinds known as bacteriophages, which only infect bacteria and are used around the world to treat patients with persistent infections. In lab tests, a cocktail of the AI-designed viruses killed E coli bugs that were resistant to natural bacteriophages.

The sheer amount of research that has gone into trying to find alternative explanations to what Behe has proposed is mind-boggling.
