Appropriate duration of dual antiplatelet therapy still unclear
A systematic review of published evidence does little to clarify the appropriate duration of dual antiplatelet therapy following drug eluting stent placement. The evidence suggests that longer duration therapy decreases the risk for myocardial infarction, but increases the risk for major bleeding events, and may provide a slight increase in mortality.

Ovarian cancer-specific markers set the stage for early diagnosis, personalized treatments
Six mRNA isoforms (bits of genetic material) produced by ovarian cancer cells but not normal cells have been identified by scientists, opening up the possibility that they could be used to diagnose early-stage ovarian cancer. What's more, several of the mRNA isoforms code for unique proteins that could be targeted with new therapeutics.

New way of preventing diabetes-associated blindness
Reporting on their study with lab-grown human cells, researchers say that blocking a second blood vessel growth protein, along with one that is already well-known, could offer a new way to treat and prevent a blinding eye disease caused by diabetes.

Patterns of brain activity reorganize visual perception during eye movements
Oscillations of activity observed in the brain could have a role in resetting the sensitivity of neurons after eye movements. Further results suggest these waves could also have a role in supporting the brain's representation of space.

Frailer older patients at higher risk of readmission or death after discharge from hospital
Frailer older patients are at higher risk of readmission to hospital or death within 30 days after discharge from a general internal medicine ward, but health care professionals can assess who is at risk using the Clinical Frailty Scale, according to a study.

Location matters in the lowland Amazon
You know the old saying: Location, location, location? It turns out that it applies to the Amazon rainforest, too. New work illustrates a hidden tapestry of chemical variation across the lowland Peruvian Amazon, with plants in different areas producing an array of chemicals that changes across the region's topography.

Special fats proven essential for brain growth
Certain special fats found in blood are essential for human brain growth and function, new research suggests. New published studies show that mutations in the protein Mfsd2a causes impaired brain development in humans. Mfsd2a is the transporter in the brain for a special type of fat called lysophosphatidylcholines (LPCs) -- composed of essential fatty acids like omega-3.

Climate engineering may save coral reefs, study shows
Mass coral bleaching, which can lead to coral mortality, is predicted to occur far more frequently over the coming decades, due to the stress exerted by higher seawater temperatures. Geoengineering of the climate may be the only way to save coral reefs from mass bleaching, according to new research.

'Pain sensing' gene discovery could help in development of new methods of pain relief
A gene essential to the production of pain-sensing neurons in humans has been identified by an international team of researchers. The discovery could have implications for the development of new methods of pain relief.

De novo assembly of a haplotype-resolved diploid genome revealed
The most complete haploid-resolved diploid genome sequence has been revealed by scientists based on de novo assembly with NGS technology. The pipeline developed lays the foundation for de novo assembly of genomes with high levels of heterozygosity, the researchers say.
