Promising malaria vaccine tested
An international research team has conducted successful phase II clinical tests of a new anti-malaria medication. The treatment led to a cure in 83 cases.
Adhesives developed to prevent bracket stains on teeth
Researchers have performed research to develop adhesive materials that will prevent white stains from appearing on the teeth of people who use brackets.
The human body's golden gate to iron traffic
New findings could change how iron metabolism in the human body is understood, and open new horizons for research and therapeutics for inflammatory diseases and neurodegenerative diseases, such as Alzheimer’s and Parkinson's disease.
Hedgehog signaling proteins keep cancer stem cells alive
Scientists have discovered that the survival of cancer stem cells is dependent on the 'Hedgehog signaling pathway'. Targeting this pathway had previously shown no effect on the growth of colorectal cancer. Now, scientists have demonstrated that using different drugs to target a specific aspect of the pathway may yield better treatment outcomes for patients.
Infant mortality rates in Texas vary dramatically from one zip code to the next
Infant mortality rates in Texas vary dramatically even across neighboring zip codes, according to a new analysis and mapping tool. The analysis and searchable map, which are the first of their kind in Texas, use data from Texas Vital Statistics Linked Birth and Death Records from 2011-2014.
Scientists Create First Stem Cells Using CRISPR Technology
In a scientific first, a research team led by Gladstone Institutes scientists turned mouse skin cells into so-called induced pluripotent stem cells by activating a specific gene using CRISPR technology. The results appear in the journal Cell Stem Cell. Pluripotent stem cells can be turned into virtually any cell type in the body. As a [...]
How plants see light
The proteins PCH1 and PCHL help plants adapt to their surroundings. Plants react sensitively to changes in their surroundings and possess the ability to adapt to them. They use the photoreceptor protein phytochrome B to see light and then regulate processes such as seed germination, seedling development, longitudinal growth and flower formation.
Free online access to millions of documents on chemical toxicity made possible through ToxicDocs
Millions of pages of internal corporate and trade association documents relating to the introduction of new products and chemicals into the workplace and commerce have been compiled into a free searchable online database called ToxicDocs.
Increasing number of adolescents receive a psychiatric or neurodevelopmental diagnosis
According to a national register study comparing Finnish birth cohorts from 1987 and 1997, an increasing number of adolescents receive a psychiatric or neurodevelopmental diagnosis. The number of diagnosed adolescents increased especially for girls in the younger cohort.
Factor that doubles the risk of death from breast cancer identified
Researchers have discovered that the risk of death from breast cancer is twice as high for patients with high heterogeneity of the estrogen receptor within the same tumor as compared to patients with low heterogeneity. The study shows that the higher risk of death is independent of other known tumor markers and also holds true for Luminal A breast cancer.
How metal scaffolds enhance the bone healing process
Scientists have shown how mechanically optimized constructs known as titanium-mesh scaffolds help optimize bone regeneration.
Let's make a deal: Could AI compromise better than humans?
Researchers developed an algorithm that teaches machines not just to win games, but to cooperate and compromise -- and sometimes do a little trash-talking too.
City lights setting traps for migrating birds
A new study has examined how light pollution lures birds into urban areas during fall migration, a trend that poses risk for the fowl that often fly into buildings and has increased with the addition of brighter LED lights. The researchers were interested in seeing what factors shape the birds' distributions and why they occur in certain areas.
Piecework at the nano assembly line
Scientists have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories.
Researchers illustrate how muscle growth inhibitor is activated, could aid in treating ALS
Researchers have identified how the inactive or latent form of GDF8, a signaling protein also known as myostatin responsible for limiting muscle, is activated.
Radioactivity from oil and gas wastewater persists in Pennsylvania stream sediments
More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new study finds that high levels of radioactivity persist in stream sediments at three disposal sites. Radioactivity at these sites is 650 times higher than at unaffected sites upstream. The contamination comes from conventional, or non-fracked, oil and gas wastewater, which, under current state regulations, can still be treated and discharged into streams.
'Explosive evolution' of techniques to restore blood flow to the brain
Recent decades have seen an 'explosive evolution' of techniques to restore blood flow to areas of the brain endangered by stroke or clogged arteries, according to a new report.
Thanks for the memory: Taking a deep look at memristors
Scientists have now unveiled the long-mysterious inner workings of these semiconductor elements, which can act like the short-term memory of nerve cells.
Creation of synthetic horsepox virus could lead to more effective smallpox vaccine
Researchers created a new synthetic virus that could lead to the development of a more effective vaccine against smallpox. The discovery demonstrates how techniques based on the use of synthetic DNA can be used to advance public health measures.
Cystic fibrosis bacterial burden begins during first years of life
Cystic fibrosis shortens life by making the lungs prone to repeated bacterial infections and inflammation. Researchers have now shown for the first time that the lungs' bacterial population changes in the first few years of life as respiratory infections and inflammation set in. This research offers a way to predict the onset of lung disease in children with CF and suggests a larger role for preventive therapies, such as hypertonic saline.
