Researchers uncover how insect antibiotic targets Gram-negative bacteria

An antibiotic called thanatin attacks the way the outer membrane of Gram-negative bacteria is built. Researchers at the University of Zurich have now found out that this happens through a previously unknown mechanism. Thanatin, produced naturally by the spined soldier bug, can therefore be used to develop new classes of antibiotics.

Biophysical mechanism involving spaghetti-like proteins helps cells avoid 'data breaches'

Cells can avoid "data breaches" when letting signaling proteins into their nuclei thanks to a quirky biophysical mechanism involving a blur of spaghetti-like proteins, researchers from the Rockefeller University and the Albert Einstein College of Medicine have shown.

Continuous tracking of melanoma cell invasion helps scientists explain key regulators of metastasis

A team of Italian scientists reported this week that blocking the interaction between urokinase receptor (uPAR) and formyl peptide receptor type 1 (FPR1) suppresses the ability of melanoma cells to migrate, invade through an extracellular matrix, and to burrow through a layer of endothelial cells.

Researchers identify cause of severe genetic disease

Mutations in the p63 protein lead to a number of disorders, but none is as severe as the AEC syndrome. Scientists at Goethe University Frankfurt in collaboration with a research group from the University of Naples Federico II have now discovered that this syndrome resembles diseases such as Alzheimer's, Parkinson's or ALS more closely than it does other p63-based syndromes.

Study findings shed new light on evolution and interaction of ancient proteins

How did protein interactions arise and how have they developed? In a new study, researchers have looked at two proteins which began co-evolving between 400 and 600 million years ago.

Research unravels how cytokines prevent multi-organ damage during parasitic infection

Cytokines are proteins secreted by several types of immune cells in response to infection, inflammation, or injury. Interleukin-17 (IL-17) is one such cytokine that causes inflammation, by controlling the production of other cytokines and mobilizing a type of white blood cell (neutrophil) that fights infections.

IBS scientists develop Nano MRI Lamp for smarter diagnosis of diseases

A research team led by CHEON Jinwoo at the Center for Nanomedicine, within the Institute for Basic Science, developed the Nano MRI Lamp: A new technology platform that tunes the magnetic resonance imaging signals "ON" only in the presence of the targeted disease.

Overcoming gene silencing barriers to target neurological conditions: an interview with Dr Errol de Souza

Many gene mutations that cause neurological disorders have been identified. For example, in a rare neurological disorder such as Huntington’s disease, an autosomal dominant mutation through expansion of CAG (cytosine-adenine-guanine) triplet repeats in the gene coding for the Huntingtin protein results in abnormal protein production.
