A better understanding of methane-digesting bacteria

A recent study has revealed new information about the inner workings of methanotrophs, bacteria that metabolize methane for their source of energy. This process requires copper, and Northwestern University researchers have pinpointed two new proteins that help methanotrophic bacteria acquire copper from their surrounding environment. These findings have a variety of potential applications, both medical

A tale of the cell cycle gone wrong

The cell cycle is an intricate and coordinated process that is vital to sustain life. In higher eukaryotes, the cell cycle produces daughter cells identical to the mother cell to renew tissues in internal organs like the liver, skin and hair. The cell has checkpoints along the way to halt the cycle if something goes

New ways to combat antibiotic-resistant pneumonia

Like many other bacterial infections that affect humans, pneumonia has acquired a significant amount of antibiotic resistance, rendering traditional means of treatment ineffective. Researchers have been trying to find new ways to fight pneumonia and other infections for better treatment of patients. Recently, researchers led by Dr. Qingming Hou of Boston Children’s Hospital and Dr.

How red blood cells get their shape

Red blood cells must maintain a distinct dimpled shape as they travel through the body, returning to form even after pushing through narrow capillaries. Misshapen red blood cells are associated with disorders such as sickle cell anemia, and though red blood cells are well-studied, there are still unanswered questions about how healthy ones properly maintain

Commensal skin bacteria produces anti-cancer agent

The skin is the largest organ of the human body with a primary function of providing a physical barrier to potentially harmful pathogens and toxic substances. Since the skin acts as an interface with the environment, it is, consequently, colonized with a diverse community of microbes. The types of microbes present are determined by the

New insights into ribosome biogenesis

Scientists have uncovered new details about human ribosome production, pinpointing more than 100 regulators from a variety of cellular pathways with unexpected control over ribosome creation. The research team, from Yale University, hopes these findings can lead to a better understanding of the connection between ribosomes and human diseases such as cancer. The study was

Learning about human disease from unique animal traits

Scientists from the University of Utah Health are using animals’ unique traits to identify regions of the human genome that might affect our own health and disease. Their study was recently published in the journal Cell Reports. The research team focused on the noncoding region that compromises 98% of the mammalian genome, but whose role

Targeting mosquito lipids to inhibit Zika replication

Viruses such as Zika and dengue are transmitted by the mosquito Aedes aegypti. When the insect bites an infected human host for a blood meal, the virus initially infects the epithelium lining the insect’s midgut and then continues to replicate in multiple tissue types. Eventually the virus is found in the mosquito’s salivary glands and

The big world of nanotechnology

Nanotechnology refers to matter between 1 and 100 nanometers, known as the nanoscale. A nanoparticle is 10-100nm in one dimension and is defined to behave as a single, whole entity. Nanoparticles are used in a variety of systems, including energy, textiles, cosmetics, sports and medicine. Scientists and engineers have been working with nanoparticles to improve
