When disaster strikes, you want the very best tools, functioning at their peak. In the case of catastrophic earthquakes, tornadoes, or even bombings in war zones, those tools are search and rescue dogs. But researchers have found that getting dogs to disaster sites can add to the animals' stress.
A Northern Illinois University study finds that tallgrass prairie restoration at a large Illinois preserve is working at a foundational level -- in the soil. Bacteria in the soil are recolonizing and recovering on their own to resemble soil found in remnant prairies. The study shows that a carefully managed restoration can produce successes even beyond plant and animal biodiversity.
Scientists have found a new way to protect stem cells from harsh inflammation during wound repair. In a study recently published in the journal Cytotherapy, researchers in India discovered that treating mice with a common anti-inflammatory drug called celecoxib promoted stem cell survival and healing when they injected the cells into wounds.
Municipal wastewater may become a key ally in the fight against antibiotic-resistant disease-causing bacteria and fungi, a new study at Stellenbosch University (SU) in South Africa found.
University of South Florida biologists have found that a crucial window in the development of tadpoles may influence a frog's later ability to fight infectious diseases as an adult.
In addition to the Cas9 protein that bacteria use to bind and snip DNA, bacteria have other Cas proteins that know where to insert that viral DNA into the CRISPR region to remember which viruses have attacked and mount a defense. A UC Berkeley team has discovered how these proteins -- Cas1 and Cas2 -- locate and insert the viral DNA, and it relies on the flexibility of these enzymes and the shape of the DNA.
You can lead a doctor to disinfection, but how do you get them to clean ... or wipe ... or swab a stethoscope? That's the question raised by a new quality improvement project published in the July issue of the American Journal of Infection Control, the official journal of the Association for Professionals in Infection Control and Epidemiology. It is the latest report to find that healthcare providers rarely perform stethoscope hygiene between patient encounters, despite its importance for infection prevention.
Most scientific research on the root-soil interactions of legumes focuses on rhizobia and nitrogen-fixing root nodules. However, many forms of non-rhizobia bacteria are also detected in these nodules. What are their role in the plant's biome? This research review published in the new, open-access Phytobiomes journal highlights studies from throughout the world on these lesser-known bacteria, as well as discusses their possible role in the bacterial community and the likely benefits for the host plant.
Chronic obstructive pulmonary disease (COPD) can result in structural changes within the lungs over time. Scientists at the Helmholtz Zentrum München have now been able to show that these changes not only affect the organ itself, but also the bacteria that live in the lung. The results have been published in PLOS ONE.
Many animal species display flocking behavior, but the fact that microorganisms do is not as well known. Researchers at Lund University in Sweden have now shown that algae and bacteria form flocks at very low concentrations of individuals, a finding that could increase our future understanding of how the organisms infect their host animals.
