Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Study shows cathepsin B can be used as biomarker for traumatic brain injury

Scientists at the Walter Reed Army Institute for Research (WRAIR) have recently demonstrated that cathepsin B, a well-studied protein important to brain development and function, can be used as biomarker, or indicator of severity, for traumatic brain injury.

Study solves longstanding mysteries about frogs

Frogs and toads are green for a very good reason - it makes them harder to see in their leafy environments. Good camouflage allows them to eat and not be eaten. But not all frogs have arrived at this life-saving greenness in the same way.

Study reveals the role of Rubisco enzymes in carbon-fixing machinery of cyanobacteria

Researchers from the University of Liverpool have provided a new understanding of how cyanobacteria build the organelles that are crucial for their potential to photosynthesize.

Researchers use super-resolution microscopy to study close protein associations

With the advent of super-resolution microscopy, scientists can study close protein associations better than ever before.

TMEM106B gene reveals the causes of neurodegenerative diseases

Across the globe, approximately 50 million people are living with dementia. The two most common forms are Alzheimer's disease and frontotemporal lobar degeneration (FTLD), which develop when neurons in specific parts of the brain stop functioning - triggering memory loss and other behavioral or personality changes.

Structural analysis of SARS-CoV-2 spike protein offers clues about the virus' evolution

Researchers at the Francis Crick Institute have characterized the structure of the SARS-CoV-2 spike protein as well as its most similar relative in a bat coronavirus. The structures provide clues about how the spike evolved and could help inform vaccine design.

New type of molecular editor can make precise changes in mitochondrial DNA

The genome in mitochondria -- the cell's energy-producing organelles -- is involved in disease and key biological functions, and the ability to precisely alter this DNA would allow scientists to learn more about the effects of these genes and mutations.

New method can help estimate environmental DNA levels in aquatic ecosystems

Ecologists have started to intensely study such DNA molecules, known as environmental DNA, to evaluate how macro-organisms are distributed.

Plant tissue succulence engineering can be used to improve drought and salinity tolerance

After several years of experimentation, scientists have engineered thale cress, or Arabidopsis thaliana, to behave like a succulent, improving water-use efficiency, salinity tolerance and reducing the effects of drought.

Discovery of new step in brain cell mechanism could lead to new treatments for epilepsy

Researchers have identified a critical new step in how brain cells function in people with one of the most common forms of epilepsy.

Scientists develop CRISPR-assisted method to detect RNA-binding proteins in living cells

While scientists still don't fully understand the diverse nature of RNA molecules, it is believed that the proteins binding to them, called RNA-binding proteins, are associated with many disease formation.

Long-term culture of human pancreatic slices as a model to study regeneration of beta cells

Scientists from the Diabetes Research Institute at the University of Miami Miller School of Medicine have developed a method allowing for the long-term culture of "pancreatic slices" to study the regeneration of the human pancreas in real time.

Wild strains of salmonella find a backdoor entry into plants

As the world wrestles with the coronavirus (COVID-19) pandemic, which arose after the virus jumped from an animal species to the human species, University of Delaware researchers are learning about new ways other pathogens are jumping from plants to people.
