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 reveals new strategy to combat antibiotic resistance

A new strategy to combat antibiotic resistance has emerged from a study led by researchers at Baylor College of Medicine. Published in the journal Molecular Cell, the report reveals for the first time how bacteria evolve mutations that confer antibiotic resistance and that this process can be inhibited with FDA-approved drug edaravone.

New analysis establishes global microbial signatures for colorectal cancer

Cancers have long been known to arise due to environmental exposures such as unhealthy diet or smoking. Lately, the microbes living in and on our body have entered the stage as key players: while stomach cancer can be caused by a single bacterial species, Helicobacter pylori, the role that gut microbes play in the development of colorectal cancer - the third most common cancer worldwide - is less clear.

Gut microbiota can help predict occurrence of colorectal cancer

Gut microbiota - the population of microbes that live in our intestine - can be used to predict the occurrence of colorectal cancer, the second most common type of cancer in women and the third in men.

Scientists have more evidence of why clear margins in breast cancer surgery are such good news

When a breast cancer tumor is removed with no signs of cancer left behind, it's great news for patients, and now scientists have more evidence of why.

Novel EU-funded project in the field of genomics

The European Advanced infraStructure for Innovative Genomics (EASI-Genomics), a project funded under the European Union's research and innovation programme Horizon 2020, will provide researchers free-of-charge access to cutting-edge European genomics facilities.

Designer organelles in living mammalian cells can build synthetic proteins

A research team led by biophysical chemist Professor Edward Lemke has engineered a designer organelle in a living mammalian cell in a new complex biological translation process. The created membraneless organelle can build proteins from natural and synthetic amino acids carrying new functionalities.

Michigan State University receives $1.8 million NIH grant to improve brain implants

Michigan State University has landed a $1.8 million National Institutes for Health R01 grant to improve brain implants - "electroceuticals" used to treat Alzheimer's, Parkinson's, depression and traumatic injuries.

Higher levels of sex hormones in older men related to lower biological age

Older men tend to have lower biological age if they have higher levels of sex hormones, particularly the estradiol form of estrogen, a large new study from Australia finds.

Bacteria may travel thousands of miles through the air worldwide, Rutgers study suggests

Bacteria may travel thousands of miles through the air worldwide instead of hitching rides with people and animals, according to Rutgers and other scientists. Their "air bridge" hypothesis could shed light on how harmful bacteria share antibiotic resistance genes.

New molecular mechanism involved in pancreas repair identified

Ramón Muñoz-Chápuli and Rita Carmona, researchers of the UMA Department of Animal Biology, have identified a new molecular mechanism involved in pancreas repair.

Surprising discovery offers clues to limit graft-vs.-host disease

A protein that protects people with inflammatory bowel disease has quite a different effect in graft-vs.-host disease, a common and challenging side effect of bone marrow transplants.

Hidden differences between pathology of CTE and Alzheimer's disease discovered

An international team of scientists at Indiana University School of Medicine, University of Kansas and the U.K. Medical Research Council have dismantled the belief that Alzheimer's disease and Chronic Traumatic Encephalopathy have identical pathology.

Miniature brains that can move muscles, grown in the lab

Researchers have successfully created miniature organoid brains in the labs that when attached to a spinal cord and muscles could help move the muscles.

Current HBV genome sequences help deduce ancient human population movements into Australia

Australian researchers have used current hepatitis B virus (HBV) genome sequences to deduce ancient human population movements into Australia, adding weight to the theory that the mainland Aboriginal population separated from other early humans at least 59 thousand years ago and possibly entered the country near the Tiwi Islands.

New proteomics-based test could aid in early detection of ovarian cancer

Fewer than half of ovarian cancer patients survive until five years after diagnosis. According to the American Cancer Society, this is because only about one-fifth of ovarian cancer cases are detected early, when the chances of successful treatment and recovery are highest.

Molecular patterns could help predict relapse risk in breast cancer patients

The genetic and molecular make-up of individual breast tumors holds clues to how a woman’s disease could progress, including the likelihood of it coming back after treatment, and in what time frame, according to a Cancer Research UK-funded study published in Nature today (Wednesday).
