ASU study explores components of the immune system

Unless you are an identical twin, you probably aren't often mistaken for someone else. Likewise, our own sense of self as distinct from all other humans is deeply ingrained since early childhood.

Stem cell model could provide insights into biological mechanisms that underlie neuropsychiatric disorders

Researchers from the Icahn School of Medicine at Mount Sinai have applied a novel stem cell model to map disease risk variants in human neurons, which could help provide insights into the biological mechanisms that underlie neuropsychiatric disorders such as autism and schizophrenia.

Microgravity culture during spaceflight enhances microbial infection process in 3D intestinal models

Infectious microbes have evolved sophisticated means to invade host cells, outwit the body's defenses and cause disease.

Study identifies how ketamine works as a rapid antidepressant

Ketamine is the speedster of antidepressants, working within hours compared to more common antidepressants that can take several weeks. But ketamine can only be given for a limited amount of time because of its many side effects.

Surprising outcomes trigger release of noradrenaline in the brain, MIT study finds

When your brain needs you to pay attention to something important, one way it can do that is to send out a burst of noradrenaline, according to a new MIT study.

Scientists unlock the cellular secrets of aging process

New research has uncovered how genetic changes that accumulate slowly in blood stem cells throughout life are likely to be responsible for the dramatic change in blood production after the age of 70.

Membrane lipid stops stress reactions and inhibits cell death

Programmed cell death is an important tool that an organism uses to keep itself healthy. When a cell does not function as it should, various stress reactions are activated. The goal of these reactions is to restore the original cell function.

Study finds a link between aging and cancer metastases

Spreading cancer cells that escape a primary tumor site can seed in tissues distant from the tumor, but may take several years or decades to grow into full metastatic cancers.

Researchers identify chemical compound that may short-circuit brain cell death in Parkinson's disease

In studies in mice, Johns Hopkins Medicine researchers say they have identified a chemical compound that stops the final events in the pathway linked to the death of brain cells in Parkinson's disease.

New findings reveal potential mechanisms for cellular defects in human laminopathies

A Northwestern Medicine study has uncovered distinct roles for major nuclear lamin isoforms in maintaining intracellular interactions and cellular mechanics, according to findings published in the Proceedings of the National Academy of Sciences.

UCI-led study identifies sex-specific circuits of muscle signaling to other tissues

A new University of California, Irvine-led study identifies sex-specific circuits of muscle signaling to other tissues and that the organs and processes muscle impacts are markedly different between males and females.

Aging does not influence liver renewal, research shows

The liver has a unique ability to regenerate after damage. However, it was unknown whether this ability decreases as we age.

Researchers discover how a workhorse protein keeps protein production on track

Cells produce proteins like little factories. But if they make too much at the wrong times it can lead to diseases like cancer, so they control production with a process called RNA interference (RNAi).

Scientists discover a new role for protein complex at the center of Bardet-Biedl syndrome

Scientists have identified a new role for a protein complex at the center of a human genetic disorder called Bardet-Biedl syndrome, or BBS, for which there is currently no cure.

IOB's new scRNA-seq protocol provides a snapshot of the cell transcriptome at unprecedented resolution

Single-cell RNA-sequencing (scRNA-seq) shows which genes are turned on in a cell and what their level of transcription is. This allows in-depth assessment of the biology of individual cells, and detection of changes that may indicate disease.

Interactive web portal details the extent of splicing events in noncoding sequences

An online tool reveals the extent of gene-restructuring events in noncoding sequences.

Gene linked to severe learning disabilities plays a key role in cells' response to environmental stress

A gene that has been associated with severe learning disabilities in humans has been found to also play a vital role in cells' response to environmental stress, according to a Duke University study appearing May 24 in the journal Cell Reports.

Using diffusion-weighted MRI to visualize brain inflammation in vivo for the first time

Research of the laboratories led by Dr. Silvia de Santis and Dr. Santiago Canals, both from the Institute of Neurosciences UMH-CSIC (Alicante, Spain), has made it possible to visualize for the first time and in great detail brain inflammation using diffusion-weighted Magnetic Resonance Imaging.
