Light can be utilized to control gene function

Fri, 21/04/2017 - 1:15pm
Light can be used as an accurate method to control gene expression, shows groundbreaking optogenetics study. In a new study, the researchers were able to induce and inhibit the expression of genes in mammalian cell cultures and were able to regulate intracellular protein levels using light signals. The approach was also used to regulate gene transcription at endogenous genomic sites when combined with CRISPR/Cas9 technology.

3D-printing of glass now possible

Fri, 21/04/2017 - 1:15pm
Three-dimensional printing allows extremely small and complex structures to be made even in small series. A new method now allows glass to be used for this technique. As a consequence of the properties of glass, such as transparency, thermal stability and resistance to acids, the use of this material in 3D-printing opens up manifold new applications in production and research, such as optics, data transmission, and biotechnology.

Can airborne viruses survive in water?

Fri, 21/04/2017 - 1:15pm
A new study challenges the tenet that herpes viruses, like most enveloped viruses, are relatively unstable outside their host. Under a variety of conditions equine herpesvirus remained stable and infectious over a three week period. This suggests that untreated water could be a source of infection by some herpesviruses.

Medical history reveals multiple sclerosis begins to impact patients sooner

Fri, 21/04/2017 - 12:49pm
People with multiple sclerosis can show signs of something wrong five years before the onset of disease, much earlier than previously thought, according to a new analysis of health records from people with the condition.

Fecal microbiota transplants improve cognitive impairment caused by severe liver disease

Fri, 21/04/2017 - 12:49pm
Fecal transplantation of bacteria from one healthy donor into patients that suffer from hepatic encephalopathy, is safe and improves cognitive function compared with standard of care treatment for the condition, new research concludes. The study results also demonstrated that the number of hospitalizations following fecal transplantation plus antibiotics was two, compared to the standard of care arm, which was 11.

Investigational dose of oral interferon-free treatment can cure hepatitis C in children

Fri, 21/04/2017 - 12:49pm
A study that evaluated an investigational dosage of once-daily ledipasvir 45 mg/sofosbuvir 200 mg (LDV/SOF) in children aged six to 11 years infected with HCV, found that 99 percent of children had undetectable levels of HCV-RNA 12 weeks after treatment, report researchers. The study showed that the fixed-dose combination of LDV/SOF was well-tolerated, and no patients experienced serious adverse events related to the study drug.

Diet high in animal protein is associated with NAFLD in overweight people

Fri, 21/04/2017 - 12:49pm
A diet high in animal protein was associated with a higher risk of non-alcoholic fatty liver disease (NAFLD), a condition in which fat builds up in the liver, new research has found. These findings demonstrated that fructose consumption per se might not be as harmful as previously assumed.

Origins of Indonesian Hobbits finally revealed

Fri, 21/04/2017 - 12:49pm
The most comprehensive study on the bones of Homo floresiensis, a species of tiny human discovered on the Indonesian island of Flores in 2003, has found that they most likely evolved from an ancestor in Africa and not from Homo erectus as has been widely believed.

Newborns get infection protection, not just digestion, from gut bacteria, new study in mice shows

Thu, 20/04/2017 - 9:19pm
Hundreds of thousands of babies worldwide die every year from infections that ravage their digestive systems. New research in mice offers evidence that the difference in survival may come from certain bacteria in their guts, called Clostridia, which appear to provide key protection against infection, in addition to helping digest food.

Is soda bad for your brain? (And is diet soda worse?)

Thu, 20/04/2017 - 8:22pm
Excess sugar -- especially the fructose in sugary drinks -- might damage your brain, new research suggests. Researchers found that people who drink sugary beverages frequently are more likely to have poorer memory, smaller overall brain volume, and a significantly smaller hippocampus. A follow-up study found that people who drank diet soda daily were almost three times as likely to develop stroke and dementia when compared to those who did not.

Study overturns seminal research about the developing nervous system

Thu, 20/04/2017 - 8:21pm
New research overturns a long-standing paradigm about how axons grow during embryonic development. The findings of the study could help scientists replicate or control the way axons grow, which may be applicable for diseases that affect the nervous system, such as diabetes, as well as injuries that sever nerves.
