A lightweight, ultra-shock-absorbing foam made from carbon nanotubes is so good at absorbing and dissipating the energy of an impact, it could vastly improve helmets and prevent concussions and other traumatic brain injuries.

Antibiotic treatment disrupts the balance of beneficial and harmful bacteria in a person's gut. That disruption can lead to the overgrowth of fungal species in the gut mycobiota, including the common intestinal yeast Candida albicans. However, researchers only have a limited understanding of the underlying mechanisms. Researchers now report on how treatment with a common beta-lactam antibiotic led to significant changes in C. albicans in patients.

About 600 seemingly disparate fungi that had resisted categorization have been shown to have a common ancestor, according to a a research team that used genome sequencing to give these peculiar creatures a new classification home.

Infectious diseases experts warn of the rising threat and apparent spread of disease-causing fungi outside their traditional hot spots. Fungal lung infections are commonly misdiagnosed, leading to delays in treatment and increase in antimicrobial resistance in the community.

A genetic survey of porcini mushrooms across the Northern Hemisphere found that these delicious fungi evolved in surprising ways -- contrary to the expectations of many who think that geographic isolation would be the primary driver for species diversity. In fact, there are regions in the world where porcini maintain their genetic distinctiveness in local ecological niches, even if they are not isolated geographically from other genetic lineages.

Researchers found that the fungus Metarhizium robertsii removes mercury from the soil around plant roots, and from fresh and saltwater. The researchers also genetically engineered the fungus to amplify its mercury detoxifying effects. This new work suggests Metarhizium could provide an inexpensive and efficient way to protect crops grown in polluted areas and remediate mercury-laden waterways.

Researchers have discovered that the three main kinds of soil fungi that cause lung infections have all expanded their ranges in recent decades. Reliance on outdated maps could be causing delayed or missed diagnoses.

Researchers have published a new theory for making batches of carbon nanotubes with a single, desired chirality. Their method could simplify purification of nanotubes that are all metallic or all semiconductors.

Yeast is not the simple single-celled microorganism we once thought, but a competitive killer. When starved of glucose, yeast releases a toxin that will poison other microorganisms that have entered its surrounding habitat, even its own clones. This venomous phenomenon was previously unknown and contributes to our understanding of unicellular microorganism behavior, the evolution of unicellular to multicellular organisms, as well as having potentially useful applications for the food industry.

A recent study has proposed a strategy to synthesize single-crystalline graphite films orders of magnitude large, up to inch scale.

Chemists and engineers have discovered a fundamental friction law that is leading to a deeper understanding of energy dissipation in friction and the design of two-dimensional materials capable of minimizing energy loss.

The formation of fruiting bodies for sexual reproduction is a central developmental process in fungi. Even though genetic methods have been applied in recent decades to identify a large number of factors involved in this process, we still lack an understanding of how the formation of different cell types is regulated. A research team has gained new insights by studying a mutant sac fungus that is infertile. The mutant is impaired in its respiratory chain, thus lacking the energy to form fruiting bodies.

A recent experiment provides evidence of a bark beetle species' agricultural capability. The fruit-tree pinhole borer can suppress the growth of weed fungi and promote food fungi.

Engineers synthesized aligned forests of nanoscale fibers made of boron nitride, or 'white graphene.' They hope to harness the technique to fabricate bulk-scale arrays of these nanotubes, which can then be combined with other materials to make stronger, more heat-resistant composites, for instance to shield space structures and hypersonic aircraft.

Researchers have identified a specific T cell that produces cytokines necessary for immunity against fungal pathogens. The finding could hasten development of effective fungal vaccines. Fungal pneumonia was a deadly comorbidity in COVID infections globally.
