Gut cells alert the body to danger during parasite invasion

To effectively combat an infection, the body first has to sense it's been invaded, then the affected tissue must send out signals to corral resources to fight the intruder.

Researchers develop new drug discovery method targeting membrane proteins on live cells

A research team led by Dr Xiaoyu LI from the Research Division for Chemistry, Faculty of Science, in collaboration with Professor Yizhou LI from School of Pharmaceutical Sciences, Chongqing University and Professor Yan CAO from School of Pharmacy, Second Military Medical University in Shanghai has developed a new drug discovery method targeting membrane proteins on live cells.

Self-learning algorithms can help analyze biological image data

Imaging techniques enable a detailed look inside an organism. But interpreting the data is time-consuming and requires a great deal of experience.

Protein encourages similar developing cells to clump together

Tohoku University scientists have, for the first time, provided experimental evidence that cell stickiness helps them stay sorted within correct compartments during development.

Polygenic risk scores from multi-population data could improve IBD predictions

Using genetic data from nearly 30,000 people, Mount Sinai researchers have built risk scores from a combination of datasets representing distinct ancestral populations that improve prediction of risk for inflammatory bowel diseases (IBD) including Crohn's disease and ulcerative colitis. The study was published in Gastroenterology on December 24.

Study clarifies the effect of aging on hematopoietic stem cells

By transferring mouse aged hematopoietic stem cells (aged HSCs) to the environment of young mice (bone marrow niche), it was demonstrated that the pattern of stem cell gene expression was rejuvenated to that of young hematopoietic stem cells.

New device for investigating intrinsic extracellular pH dynamics in the brain

Researchers at Tohoku University have developed the first all-in-one miniature pH probe for real-time investigations of intrinsic extracellular pH dynamics in the deep brain structures.

Researchers find mechanism underlying plasticity in adult brains

Developing brains constantly sprout new neuronal connections called synapses as they learn and remember. Important connections — the ones that are repeatedly introduced, such as how to avoid danger — are nurtured and reinforced, while connections deemed unnecessary are pruned away.

Researchers create a molecular catalog that describes different types of neurons

Retinal ganglion cells (RGCs) are the bottleneck through which all visual impressions flow from the retina to the brain. A team from the Max Planck Institute of Neurobiology, University of California Berkeley and Harvard University created a molecular catalog that describes the different types of these neurons.

A short-cut in photosynthetic machinery can allow needles of pine trees to stay green

How can conifers that are used for example as Christmas trees keep their green needles over the boreal winter when most trees shed their leaves?

Researchers discover how shattered chromosomes make cancer cells more aggressive

Cancer is one of the world's greatest health afflictions because, unlike some diseases, it is a moving target, constantly evolving to evade and resist treatment.

Researchers identify new weapon to battle the rising tide of antibiotic-resistant bacteria

As scientists around the globe wage war against a novel, deadly virus, one University of Colorado Boulder lab is working on new weapons to battle a different microbial threat: a rising tide of antibiotic-resistant bacteria which, if left unchecked, could kill an estimated 10 million people annually by 2050.

Researcher discovers seven DNA fingerprints that define cancer risk

Lifestyle, or put another way 'bad habits', is one of the textbook explanations for why some people are at higher risk for cancer.

Study uncovers a new paradigm for the role of the thymus in pregnancy

How the immune system adapts to pregnancy has puzzled researchers for decades. An international team of researchers, including scientists from IMBA – Institute of Molecular Biotechnology of the Austrian Academy of Sciences – has now discovered that important changes in the thymus occur in order to prevent miscarriages and gestational diabetes.
