New study shows microRNAs play important role in inducing asthma

A new study shows that microRNAs, which are small, noncoding RNA molecules that can silence genes, have an important role in inducing asthma. [More]
Scientists isolate antibodies capable of neutralizing dengue and Zika virus

Scientists isolate antibodies capable of neutralizing dengue and Zika virus

Scientists from the Institut Pasteur and the CNRS, in collaboration with Imperial College London and the University of Vienna, Austria, have identified antibodies that can efficiently neutralize both the dengue virus and the Zika virus. [More]
Study reveals surprising diversity in single neuronal transcriptomes of the brain

Study reveals surprising diversity in single neuronal transcriptomes of the brain

A team of scientists at The Scripps Research Institute, University of California, San Diego and Illumina, Inc., has completed the first large-scale assessment of single neuronal "transcriptomes." [More]
IU researchers identify suite of genes that play role in nerve sensitivity

IU researchers identify suite of genes that play role in nerve sensitivity

Indiana University researchers have that found a suite of genes in both fruit flies and humans -- including one dubbed "smoke alarm" -- plays a role in nerve sensitivity. The study could help lead to new drug targets in pain management. [More]
Long-term suppression of neurotransmitter acetylcholine may lead to dementia-like changes in the brain

Long-term suppression of neurotransmitter acetylcholine may lead to dementia-like changes in the brain

A new study from Western University is helping to explain why the long-term use of common anticholinergic drugs used to treat conditions like allergies and overactive bladder lead to an increased risk of developing dementia later in life. [More]
Scientists discover RNA methylation could strengthen memory formation

Scientists discover RNA methylation could strengthen memory formation

New insight into the process that converts experiences into stable long-term memories has been uncovered by neurobiologists from the University of California, Irvine and the University of Queensland. [More]
Researchers reveal DNA unwrapping can happen asymmetrically to expose specific genes

Researchers reveal DNA unwrapping can happen asymmetrically to expose specific genes

The protein complex that holds strands of DNA in compact spools partially disassembles itself to help genes reveal themselves to specialized proteins and enzymes for activation, according to Rice University researchers and their colleagues. [More]
Mobile devices of healthcare workers often contaminated by viral RNA

Mobile devices of healthcare workers often contaminated by viral RNA

In clinical settings, mobile phones benefit patients by placing useful data and information at the fingertips of health professionals during interactions on the ward. [More]
Scientists join together to map urban subway microbiome

Scientists join together to map urban subway microbiome

Scientists at the Centre for Genomic Regulation in Barcelona, Spain, have joined today the Global City Sampling Day for the MetaSub research project. Started in 2013 in New York and led by Dr. Christopher E Mason at Weill Cornell Medicine, MetaSub is an international consortium of laboratories to establish a world-wide "DNA map" of microbiomes in mass transit systems.

First CRISPR/Cas9 screen helps identify human proteins required for Zika virus replication

First CRISPR/Cas9 screen helps identify human proteins required for Zika virus replication

Scientists at the University of Massachusetts Medical School have performed the first CRISPR/Cas9 screen to discover human proteins that Zika virus needs for replication. [More]
Drexel University researchers aim to identify new molecular mechanisms involved in chronic pain

Drexel University researchers aim to identify new molecular mechanisms involved in chronic pain

Chronic pain is one of the most prevalent, disabling and expensive public health crises in the United States. It affects more than 100 million Americans, with annual costs estimated at $635 billion, says a 2014 report from the American Pain Society. [More]
Rice University researchers synthesize new anti-cancer agent

Rice University researchers synthesize new anti-cancer agent

Rice University scientists have synthesized a novel anti-cancer agent, Thailanstatin A, which was originally isolated from a bacterial species collected in Thailand. [More]
New method helps analyse how cold viruses penetrate into cells

New method helps analyse how cold viruses penetrate into cells

Cold viruses cause us irritation by penetrating into our cells and transporting their RNA into the cytoplasma of the infected cells. This is the only way they can multiply. The details of how the transfer of the RNA from within the virus occurs are difficult to study. [More]
Absence of one specific species of gut bacteria causes autism-related social deficits in mice

Absence of one specific species of gut bacteria causes autism-related social deficits in mice

The absence of one specific species of gut bacteria causes social deficits in mice, researchers at Baylor College of Medicine report June 16 in Cell. By adding this bacterial species back to the guts of affected mice, the researchers were able to reverse some of the mice's behavioral deficits, which are reminiscent of symptoms of autism spectrum disorders (ASDs) in humans.

RVFV uses cancer pathway to hijack host cell and cause infection

RVFV uses cancer pathway to hijack host cell and cause infection

Viruses can't live without us -- literally. As obligate parasites, viruses need a host cell to survive and grow. Scientists are exploiting this characteristic by developing therapeutics that close off pathways necessary for viral infection, essentially stopping pathogens in their tracks. [More]
Researchers clarify cause of heart arrhythmia in myotonic dystrophy

Researchers clarify cause of heart arrhythmia in myotonic dystrophy

An international joint research group found that the cause of heart arrhythmia in myotonic dystrophy was RNA abnormalities in the sodium channel in the heart, clarifying the symptom's mechanism. This finding will be helpful in prevention and early intervention of death in this disease, leading to the development of new treatment. [More]
Innovative computer HIV capsid model provides real insight into virus maturation process

Innovative computer HIV capsid model provides real insight into virus maturation process

From a virus's point of view, invading our cells is a matter of survival. The virus makes a living by highjacking cellular processes to produce more of the proteins that make it up. [More]
Four miRNAs may hold vital clue to disease progression in gliobastoma

Four miRNAs may hold vital clue to disease progression in gliobastoma

Scientists at the Helmholtz Zentrum M√ľnchen and the Ludwig Maximilians University of Munich have developed a new method of predicting disease progression in gliobastoma patients who have undergone standard treatment. [More]
CD36 receptor in nasal sensory neurons may be linked to preference for fatty food

CD36 receptor in nasal sensory neurons may be linked to preference for fatty food

A paper by Brazilian researchers published in the journal Scientific Reports describes a study showing that a subgroup of olfactory neurons in the nasal cavity express a cellular receptor specializing in the transport of lipid molecules. [More]
