Stanford researchers explore how enzyme changes and becomes antibiotic-resistant

Enzymes are proteins that speed up or catalyze a reaction in living organisms. Bacteria can produce enzymes that make them resistant to antibiotics.

Study reveals functional dynamics of ion channels

Most ion channels are very selective about the ions, which may or may not pass through them. They may be conductive for potassium ions and non-conductive for sodium ions or vice versa.

Key protein involved in epigenetic regulation of gene expression guides skin cell renewal

Approximately once a month, our skin completely renews itself. If this highly coordinated process goes awry, it can lead to a variety of skin diseases, ranging from skin cancer to psoriasis.

Father's stress affects the brain development of offspring, mice study shows

New research in mice has found that a father's stress affects the brain development of his offspring. This stress changes the father's sperm, which can then alter the brain development of the child. This new research provides a much better understanding of the key role that fathers play in the brain development of offspring.

Study explores link between mortality risk and combustible tobacco use

Contemporary population estimates suggest that like cigarette-only smokers, current cigar-only and pipe-only smokers have a higher risk of dying from cancers known to be caused by tobacco, and cigarette and cigar smokers have a higher risk of death from any cause compared with people who never used tobacco.

Researchers develop sensing method for early detection of cancer and diabetes

The use of terahertz waves for biosensing is currently receiving considerable attention. THz waves are able to detect molecular vibrations and rotations, without using labels that can affect the properties of the substances of interest.

Scientists develop water-soluble warped nanographene for bioimaging

An international team of scientists has developed a water-soluble "warped nanographene", a flexible molecule that is biocompatible and shows promise for fluorescent cell imaging.

Emergency nurses experience regular verbal and physical abuse

The first ever review of the experience of hospital A&E staff reveals that they have resigned themselves to patient violence and aggression.

Researchers find high risk of suicide among unaccompanied refugee minors

In a report written on behalf of the Swedish National Board of Health and Welfare, researchers at Karolinska Institutet have concluded that the risk of suicide among unaccompanied refugee minors and young adults in 2017 was nine times higher than the equivalent figure for the same age group in the Swedish population.

Lab-grown cerebellar cells may help explain how ASD develops at molecular level

Increasing evidence has linked autism spectrum disorder with dysfunction of the brain's cerebellum, but the details have been unclear. In a new study, researchers at Boston Children's Hospital used stem cell technology to create cerebellar cells known as Purkinje cells from patients with tuberous sclerosis complex, a genetic syndrome that often includes ASD-like features.

Liquid biopsies could be used as new predictive marker for metastatic TNBC

A clinically relevant "liquid biopsy" test can be used to profile cancer genomes from blood and predict survival outcomes for patients with metastatic triple negative breast cancer, according to new research published by a multi-institutional team of researchers with The Ohio State University Comprehensive Cancer Center -- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute, the Dana-Farber Cancer Institute and the Broad Institute of MIT and Harvard.

Researchers reveal potential biological roots behind individuality

Scientists have studied the system that controls age-appropriate behavior and discovered a certain element of variation that may contribute to a species’ survival from an evolutionary point of view.

Researchers uncover how excess calcium may influence development of Parkinson’s disease

Researchers have found that excess levels of calcium in brain cells may lead to the formation of toxic clusters that are the hallmark of Parkinson's disease.

Early childhood immune signature predicts risk of developing asthma later on

Asthma is a chronic inflammatory disease driven by the interplay of genetics, environmental factors and a diverse cast of immune cells.

Poor awareness among parents may hinder a child's early dental care

A new survey has found that one in six parents are likely to postpone their children’s dental care visits until the age of 4 or older.

Research finds rising trend in incidence of merkel cell carcinoma

Merkel cell carcinoma is a rare type of skin cancer, affecting only a few thousand people each year, compared to tens of thousands with melanoma. But while it may not be as common as other skin cancers, MCC is highly aggressive and often deadly - and it's also becoming more common, according to new research published in the Journal of the American Academy of Dermatology and presented at the American Academy of Dermatology 2018 Annual Meeting in San Diego.

Researchers uncover Ras protein's role in uncontrolled cancer growth

Protein systems, such as Ras, make up the complex signaling pathways that control whether a cell divides or, in some cases, becomes cancerous and metastasizes into other regions of the body. For example, 98 percent of pancreatic cancers show Ras protein mutations.
