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.

New insights into the global expansion of Candida auris

The fungal species Candida auris is spreading across the globe, and gaining in virulence, according to a new review by a Hackensack Meridian Center for Discovery and Innovation (CDI) scientist and colleagues.

Epigenetic plasticity in germinal center B cells may help explain lymphoma origins

Immune cells called B cells make antibodies that fight off invading bacteria, viruses and other foreign substances. During their preparation for this battle, B cells transiently revert to a more flexible, or plastic, stem-cell-like state in the lymph nodes, according to a new preclinical study from Weill Cornell Medicine investigators.

Genes influence the gut microbiome beyond the individual

The gut microbiome - made up of trillions of microbes in the digestive tract - is vital for digestion and overall health. Diet and medication shape these microbial ecosystems, but the contribution of genetics has been more difficult to ascertain.

New grant supports research into drug-induced brain toxicity

Important FDA-approved drugs to treat HIV and cancer can save lives, but they come with their own risks. Some drugs used clinically are known to cause neurological side effects in up to half of patients, ranging from confusion and memory problems to permanent nerve damage.

New insights into how a molecular gatekeeper controls early protein modification

For years, ETH researchers have been investigating a molecular complex that plays a key role in protein synthesis. They have now discovered that this complex also contributes a crucial function in ensuring that our DNA is properly processed and “packaged”.

DNA twisting controls how cells respond to estrogen

Estrogens, the main female sex hormone, although they also perform some functions in men, are involved in a myriad of processes, which is why the body changes so much during menopause. This is because estrogens regulate hundreds of genes.

Estrogen drives gut pain and explains higher rates of IBS in women

Women are dramatically more likely than men to suffer from irritable bowel syndrome (IBS), a chronic condition causing abdominal pain, bloating, and digestive discomfort.

Opposing protein forces fine tune mRNA stability in human cells

A newly revealed molecular tug-of-war may have implications for better understanding how a multitude of diseases and disorders - including cancers, neurodegenerative diseases and immune disorders - originate, as well as how to potentially treat them, according to researchers at Penn State.

New insights into alcohol-related DNA damage and cancer risk

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA.

Australian scientists uncover key genetic drivers behind long COVID

Australian scientists have identified the key genetic drivers behind long COVID, revealing why some people continue to experience debilitating symptoms long after their initial infection.

Virus shells use asymmetry to control RNA release and infection

Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, but new research led by scientists at Penn State reveals a deliberate imbalance in their shape that helps them infect their hosts.
