Silk Road: The Untold Story

The story of Silk Road, how it grew into a $1.2 billion operation, and how federal law enforcement shut it down. The post Silk Road: The Untold Story appeared first on WIRED.

Nano-capsules designed for diagnosing malignant tumours

Researchers have developed adaptable nano-capsules that can help in the diagnosis of glioblastoma cells – a highly invasive form of brain tumor.

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.

Tommorrowland – the only Clooney movie I’ll probably never see

Guest essay by Eric Worrall The Daily Beast reports that George Clooney has done the green thing – starred in a new big budget Summer eco-disaster film, which aims to make us feel bad about warm weather.   According to The Daily Beast; … When was the last time Transformers made you think about your…

Fine-tuned molecular orientation is key to more efficient solar cells

Polymer solar cells are a hot area of research due to both their strong future potential and the significant challenges they pose. It is believed that thanks to lower production costs, they could become a viable alternative to conventional...Show More Summary

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.

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.

Complex signaling between blood, stem cells controls regeneration in fly gut

Having a healthy gut may well depend on maintaining a complex signaling dance between immune cells and the stem cells that line the intestine. Scientists report significant new insight into how these interactions control intestinal regeneration after an infection. Show More Summary

Removing mutant p53 significantly regresses tumors, improves cancer survival

For two decades cancer researchers have looked unsuccessfully for ways to develop compounds to restore the function of mutant p53 proteins. Now a team of researchers has discovered that eliminating the abnormally stabilized mutant p53 protein in cancer in vivo has positive therapeutic effects, showing that tumors regress significantly and survival increases.

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 spa...

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.

One step closer to a single-molecule device

A new technique to create a single-molecule diode has been developed by scientists, and, in doing so, they have developed molecular diodes that perform 50 times better than all prior designs. This research group is the first to develop a single-molecule diode that may have real-world technological applications for nanoscale devices.

DNA double helix does double duty in assembling arrays of nanoparticles

In a new twist on the use of DNA in nanoscale construction, scientists put synthetic strands of the biological material to work in two ways: They used ropelike configurations of the DNA double helix to form a rigid geometrical framework, and added dangling pieces of single-stranded DNA to glue nanoparticles in place.

Are bee hotels the answer in saving a species?

'Bee hotels' have been popping up as a possible aid for bee populations. But there are problems for those checking in. The post Are bee hotels the answer in saving a species? appeared first on

Researchers find the 'key' to quantum network solution

Scientists have made an important step in establishing scalable and secure high rate quantum networks. They have developed a protocol to achieve key-rates at metropolitan distances at three orders-of-magnitude higher than previously...

All sounds made equal in melancholy

The room is loud with chatter. Glasses clink. Soft music, perhaps light jazz or strings, fills the air. Amidst all of these background sounds, it can be difficult to understand what an adjacent person is saying. A depressed individual,...Show More Summary

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.

'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.

Team pinpoints genes that make plant stem cells, revealing origin of beefsteak tomatoes

A team of scientists has identified a set of genes that control stem cell production in the tomato. Mutations in these genes explain the origin of mammoth beefsteak tomatoes. More importantly, the research suggests how breeders can optimize fruit size in potentially any fruit-bearing crop.

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.
