Infected mice can be better models for human diseases

Vaccines and therapeutics developed using mice often don't work as expected in humans. New research at Washington University School of Medicine in St. Louis points to the near-sterile surroundings of laboratory mice as a key reason.

Novel combination of cancer drugs can have therapeutic impact on diffuse large B-cell lymphoma

New research from Roswell Park Cancer Institute shows that promising cancer drugs used in combination can have significant therapeutic impact on a particularly aggressive subtype of diffuse large B-cell lymphoma (DH-DLBCL) in preclinical studies. The researchers will present their findings at the American Association for Cancer Research (AACR) Annual Meeting 2016, to be held April 16-20 in New Orleans.

TSRI chemists develop new method to achieve chemical reaction in pharmaceutical industry

Scientists at The Scripps Research Institute have found a new and better way to achieve a chemical reaction that is used widely in the pharmaceutical as well as flavor and fragrance industries.

New study explores mechanisms that control size, shape of tubular organ systems

A new study from the group of Holger Gerhardt in collaboration with Katie Bentley's Lab addresses a long standing question in the wider field of developmental biology and tissue patterning in general, and in the vascular biology field in particular: 'What are the fundamental mechanisms controlling size and shape of tubular organ systems'.

Scientists develop CRISPRainbow to study genome structure in real time

CRISPRainbow, a new technology using CRISPR/Cas9 developed by scientists at UMass Medical School, allows researchers to tag and track up to seven different genomic locations in live cells. This labeling system, details of which were published in Nature Biotechnology, will be an invaluable tool for studying the structure of the genome in real time.

Researchers identify traveling spike generator that produces brain waves

Brain waves that spread through the hippocampus are initiated by a method not seen before--a possible step toward understanding and treating epilepsy, according to researchers at Case Western Reserve University.

Researchers develop fine-scale global map of Zika virus transmission

The southeastern US, including much of Texas through to Florida, have ideal conditions for spread of Zika virus according to a new study published in eLife.

Hippo signaling pathway controls phases of quiescence in fruit fly central nervous system

Neural stem cells are responsible for the formation of differentiated daughter cells in the developing brain. If no new cells are needed, the stem cells may enter a resting phase called quiescence. Biologists at Johannes Gutenberg University Mainz have now discovered that the phases of quiescence in the Drosophila fruit fly central nervous system are controlled by the Hippo signaling pathway. Drosophila serves as a model organism that helps geneticists to decode the molecular fundamentals of cellular biology and unravel mechanisms that are conserved in human beings and other vertebrates.

Scientists identify transposable element in certain bird genomes

In rare instances, DNA is known to have jumped from one species to another. If a parasite's DNA jumps to its host's genome, it could leave evidence of that parasitic interaction that could be found millions of years later -- a DNA 'fossil' of sorts.

Blocking IL-1 signalling molecule could alleviate asthma symptoms

Scientists have made a discovery that could lead to improved treatment for asthma sufferers.They have found that blocking a certain signalling molecule can alleviate symptoms such as mucus production, swelling (edema), and constriction of the airways in the lungs.

Exhaled e-cigarette vapour evaporates within seconds

A new study being presented today at the 4th Workplace and Indoor Aerosols conference in Barcelona shows, for the first time, that exhaled e-cigarette particles are liquid droplets that evaporate within seconds.

SI-2 molecule can inhibit tumor growth in breast cancer mouse model

Cancer cells communicate with their environment through cell molecules that pass on signals to the inside of the cell. The signals help cancer cells multiply and migrate, spreading the disease.

Motivational interviewing can help reduce risky use of pain pills

As America battles an epidemic of deaths from misused pain pills, a new study suggests an inexpensive way to cut risky use of these drugs by people who have a high chance of overdosing.

Important determinants of periodontal disease

Although, bacteria are a critical etiologic factor that are needed to develop periodontal disease, bacteria alone are insuficiente to induce a periodontal disease. A susceptible host is also required, and the host's susceptibility as local and/or general predisposing risk factors, are important determinants of the disease status.

Scientists map core genes involved during DNA uptake in strep bacteria

Bacteria possess the ability to take up DNA from their environment, a skill that enables them to acquire new genes for antibiotic resistance or to escape the immune response. Scientists have now mapped the core set of genes that are consistently controlled during DNA uptake in strep bacteria, and they hope the finding will allow them to cut off the microbes' ability to survive what doctors and nature can throw at them.

Dog ownership and walking increase physical health among older adults

The Centers for Disease Control and Prevention recommends that adults of all ages should engage in 150 or more minutes of moderate physical activity per week. Among adults 60 years of age or more, walking is the most common form of leisure-time physical activity because it is self-paced, low impact and does not require equipment.

Researchers find new insights on disease stages for gastric cancer patients

Diagnosis of gastric cancer in the early stages is difficult because of the lack of simple and cheap methods of inspection and specific markers of gastric cancer while the symptoms of the disease are vague and tend to overlap with other common and benign conditions. Better tumor characterization and more individualized treatment planning can be expected only with the implementation of better diagnostic tools combined with advances in molecular and genetic analysis.

Better way to model human immune system

Scientists at the University of Minnesota have developed a new way to study mice that better mimics the immune system of adult humans and which could significantly improve ways to test potential therapeutics. Published online today in the journal Nature, the researchers describe the limitations of laboratory mice for immunology research and reveal the benefits of what they are calling "dirty mice."

Bacteria-derived gut metabolites can affect brain’s myelin content and induce depression-like symptoms

Specific combinations of gut bacteria produce substances that affect myelin content and cause social avoidance behaviors in mice, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published today in the medical journal eLife. This research suggests that targeting intestinal bacteria, or their metabolites, could be one way to treat debilitating psychiatric disorders and demyelinating diseases, like multiple sclerosis.

Scientists develop new strategy to combat wide range of viruses

Scientists and health officials are marshalling forces to fight Zika, the latest in a string of recent outbreaks. Many of these efforts target that virus specifically, but some researchers are looking for a broader approach. Now one team reports in ACS' journal Macromolecules a new strategy to fight a wide range of viruses that appears to be safe in vivo and could evade a virus's ability to develop resistance.
