Bacteria do not colonize the gut before birth
Researchers examined prenatal stool (meconium) samples collected from 20 babies during breech Cesarean delivery. By including only breech caesarean deliveries in healthy pregnant women they were able to avoid the transmission of bacteria that occurs.....»»
The sun was born when a dense gas cloud collapsed 4.6 billion years ago
While the upcoming total solar eclipse is a special moment to reflect on our place in the universe, scientists have been studying the birth of the sun and the formation of our solar system for a long time......»»
Eclipses were once associated with the deaths of kings—predictions played a key role in the birth of astronomy
Making interesting predictions is one of the hallmarks of successful science. When Albert Einstein formulated his theory of general relativity, an almost immediate test involved the prediction that in a solar eclipse, light from stars that would norm.....»»
Attack and defense in the microverse: How small RNA molecules regulate viral infections of bacteria
Viruses need hosts. Whether it's measles, the flu or coronavirus, viral pathogens cannot multiply or infect other organisms without the assistance of their hosts' cellular infrastructure. However, humans are not the only ones affected by viruses: ani.....»»
Study describes zinc oxide nanoparticle strategy for inactivation of multidrug-resistant bacteria
An article published in the Journal of Environmental Chemical Engineering describes a possible strategy for promoting selective inhibition of multidrug-resistant bacteria, which are increasingly abundant owing to the indiscriminate use of antibiotics.....»»
Student cleans up archival data and uncovers two stellar cocoons
While investigating 16 years of images of young stars from a retired astronomical camera, Leiden master's student Sam de Regt discovered that two of those stars were still enveloped in birth clouds that had not been seen at this level of detail befor.....»»
Wound treatment hydrogel infused with amino acid kills bacteria naturally and promotes cell growth
Hydrogels are popular for use in skin ailments and tissue engineering. These polymer-based biocompatible materials are useful for their abilities to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture.....»»
Researchers explain how green algae and bacteria together contribute to climate protection
A research team at Friedrich Schiller University Jena, Germany has now found a bacterium that forms a team with a green alga. Both microorganisms support each other in their growth. Additionally, the bacterium helps the microalga to neutralize the to.....»»
New antibiotic class effective against multidrug-resistant bacteria discovered
Scientists at Uppsala University have discovered a new class of antibiotics with potent activity against multi-drug resistant bacteria, and have shown that it cures bloodstream infections in mice. The new antibiotic class is described in an article i.....»»
Supercomputer simulations decode the mass puzzle of the first stars
Ching-Yao Tang and Dr. Ke-Jung Chen from the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA) have made substantial progress in decoding the birth mass of the first stars using the powerful supercomputer at Berkeley National Lab......»»
Ancient Adélie penguin DNA reveals that small repeats persist for hundreds of millions of years
Microsatellites are valuable tools for studying inheritance, genetic diversity, and population dynamics across a wide range of organisms including bacteria, plants, animals, and fungi. These short, repeating sequence motifs are a common feature of bo.....»»
Study identifies protein responsible for gas vesicle clustering in bacteria
Gas vesicles are hollow structures made of protein found in the cells of certain microorganisms, and researchers at Rice University believe they can be programmed for use in biomedical applications......»»
Study finds wild nematode worms learn to avoid harmful bacteria—and their offspring inherit this knowledge
The nematode worm C. elegans will stay away from dangerous bacteria in its environment when exposed to certain bacterial RNAs—and can transmit that learned behavior to future generations. A team led by Coleen Murphy at Princeton University report t.....»»
Sniffing out bacteria: Team develops a novel approach for rapid bacterial species identification
Do you ever wonder how researchers identify bacterial infections? Traditionally, they collect samples from the infected site, grow the bacteria in a lab, and analyze them using a method called MALDI-ToF-MS. Although accurate, this method is time-cons.....»»
Biologists determine bacteria sense damage to relatives
Carnegie Mellon University biologists have discovered that Vibrio cholerae, the bacteria behind the cholera disease, can sense when its relatives die. Bacterial cell death is often accompanied by lysis, where the cell explodes, releasing internal cel.....»»
Unseen travelers: Dust storms may spread bacteria and fungi around the world
When allergy season hits, many blame their reactions on the local flora in the spring. However, African Saharan-Sahelian dust plumes, large enough to register on weather radar, travel around the globe every summer, bringing their own form of air poll.....»»
Researchers uncover key biomolecule involved in whooping cough infection
Researchers have identified a new complex-carbohydrate biomolecule, or glycan, that plays a key role in the nasal colonization of the Bordetella bacteria responsible for whooping cough. The discovery could make it possible to create a new drug or vac.....»»
Stunning James Webb images show birth and death of massive stars
The James Webb Space Telescope continues to surprise us with stunning pictures, but of what exactly? Astronomer Nienke van der Marel shows with three images how massive stars lead short but explosive lives......»»
Gut microbiota and antibiotics: Missing puzzle piece discovered
The intricacies of how intestinal bacteria adapt to their environment have yet to be fully explored. Researchers from the Helmholtz Institute for RNA-based Infection Research (HIRI) in Würzburg and the University of California, Berkeley, U.S., have.....»»
Research reveals new starting points for the rapid and targeted development of future drugs
Many important medicines, such as antibiotics and anticancer drugs, are derived from natural products of bacteria. The enzyme complexes that produce these active ingredients have a modular design that makes them ideal tools for synthetic biology. By.....»»
Non-culturable Legionella identified with sequencing
Legionnaires' disease (LD), a rare and severe type of pneumonia, is a respiratory infection caused by species of Legionella bacteria. One of the most accurate ways to diagnose LD is to perform culture on samples from a patient's lower respiratory tra.....»»
