A team of faculty has discovered new technology that will quickly and easily detect active Mycobacterium tuberculosis (TB) infection antibodies.

Scientists have transformed single-cell algae into functional perovskite materials. The team has converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by conventional synthetic production. The method can be applied to the mass production of perovskites with tunable structural and electro-optical properties from single-celled organisms.

A whole new world of antibiotics is waiting inside the viruses that infect bacteria. Scientists are making it easier to study them.

Rather than let the next outbreak take the world by surprise, two virologists say that the scientific community should invest in a four-part research framework to proactively identify animal viruses that might infect humans.

A team of investigators has identified metabolic strategies used by Clostridioides difficile to rapidly colonize the gut. The findings identify methods to better prevent and treat the most common cause of antibiotic-associated diarrhea and healthcare-acquired infections (HAIs). The team's approach has implications for understanding broader aspects of microbial metabolism, including responses to antibiotics, and production of important metabolites.

Most cells in the bodies of living things duplicate their contents and physically separate into new cells through the process of cell division. But across many species, germ cells, those that become eggs or sperm, don't fully separate. They remain interconnected through small bridges called ring canals and cluster together. In a new study, researchers uncover how it is that germ cells in fruit flies form these ring canals, a finding that they say will provide new insights into a widely shared feature of development and into diseases in which cell division is disrupted.

A new biosensor offers scientists the first dynamic glimpses of manganese, an elusive metal ion that is essential for life.

Researchers have uncovered new evidence of western pygmy possums interacting with native flowers, providing an eDNA study to simultaneously detect mammal, insect and bird DNA on flowers.

Do cesarean-born babies miss out on essential microbes? New evidence suggests that the answer may be 'no.' Researchers report that mothers are able to transfer microbes to their babies via alternative, compensatory routes. While cesarean-born babies do receive less of their mother's gut microbiome during birth, they make up for this by drinking their mother's microbes in breastmilk.

Observations of water in the disk forming around protostar V883 Ori have unlocked clues about the formation of comets and planetesimals in our own solar system.

Researchers describe a new manner of detecting microbial infection that intercepts pathogen-derived signals of growth to assess the relative threat of virulent bacteria. A nuclear hormone receptor in the nematode C. elegans senses a toxic metabolite produced by the bacterial pathogen Pseudomonas aeruginosa to activate innate immunity. These data reveal an ancient strategy that informs the origins of pathogen detection and may be among the most primordial forms of immune sensing in animals.

A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a recent experiment.

The DNA sequence of a gene in wheat responsible for resisting a devastating virus has been discovered, providing vital clues for managing more resistant crops and maintaining a healthy food supply.

Mineral particles played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, according to new research.

Once upon a time, prevailing scientific opinion might have pronounced recently published research as unneeded. Now, climate change implications have heightened the need for this line of research. Flowers emit scent chemicals called volatile organic compounds (VOCs). Earlier this year, a study identified a protein that plays a key role in helping petunias emit volatiles.

Neglected by government officials and medical professionals, parasitic infections can lead to lifelong health consequences, according to a biological anthropologist.

Livestock farming produces large quantities of greenhouse gases, especially methane, which is particularly harmful to the climate. Among other things, it escapes during the storage of animal excrement, the slurry. A study now shows that methane emissions can be reduced by 99 percent through simple and inexpensive means. The method could make an important contribution to the fight against climate change.

An international team of bee researchers has integrated a calcium sensor into honey bees to enable the study of neural information processing including response to odors. This also provides insights into how social behavior is located in the brain.
