Groundbreaking poplar study shows trees can be genetically engineered not to spread

3.8.2018   |   Press monitoring

The largest field-based study of genetically modified forest trees ever conducted has demonstrated that genetic engineering can prevent new seedlings from establishing. The "containment traits" that Oregon State University researchers engineered in the study are important because of societal concerns over gene flow – the spread of genetically...

Study finds evidence that leopard geckos can make new brain cells

1.8.2018   |   Press monitoring

University of Guelph researchers have discovered the type of stem cell allowing geckos to create new brain cells, providing evidence that the lizards may also be able to regenerate parts of the brain after injury. This finding could help in replacing human brain cells lost or damaged due to injury, aging or disease. "The brain is a complex...

Nano-sized traps show promise in diagnosing pathogenic bacterial infections

30.7.2018   |   Press monitoring

A new type of "lab on a chip" developed by McGill University scientists has the potential to become a clinical tool capable of detecting very small quantities of disease-causing bacteria in just minutes. The device designed by Sara Mahshid, Assistant Professor in the Department of Bioengineering at McGill, is made of nano-sized "islands,"...

Engineering 3-D bio-printed scaffolds to regenerate damaged peripheral nervous systems

27.7.2018   |   Press monitoring

In the last decade or so, 3-D printing has experienced a surge in popularity as the technology has become more precise and accessible. Now, researchers from the University of Saskatchewan are looking at how we can use 3-D printing to help damaged nervous systems to regrow. The peripheral nervous system, which controls the body beyond the brain...

Targeting headaches and tumors with nano-submarines

25.7.2018   |   Press monitoring

Scientists at the Mainz University Medical Center and the Max Planck Institute for Polymer Research (MPI-P) have developed a new method to enable miniature drug-filled nanocarriers to dock on to immune cells, which in turn attack tumors. In the future, this may lead to targeted treatment that can largely eliminate damage to healthy tissue. In...

The highly complex sugarcane genome has finally been sequenced

23.7.2018   |   Press monitoring

Sugarcane was the last major cultivated plant to have its genome sequenced. This was because of its huge complexity: The genome comprises between 10 and 12 copies of each chromosome, while the human genome has just two. It was an international team coordinated by CIRAD that achieved this milestone, as reported in Nature Communications on July 6....

Inhalable viruses show promise as a better way to treat lung infections

20.7.2018   |   Press monitoring

Bacteriophages are viruses that target specific strains of bacteria. They were explored in the early 20th century as potential treatments for infection, but fell by the wayside once antibiotics were discovered. However, with superbugs increasingly developing antibiotic resistance, scientists have once again started investigating how they might be...

Researchers engineer bacteria to create fertilizer out of thin air

18.7.2018   |   Press monitoring

In the future, plants will be able to create their own fertilizer. Farmers will no longer need to buy and spread fertilizer for their crops, and increased food production will benefit billions of people around the world, who might otherwise go hungry. These statements may sound like something out of a science fiction novel, but new research by...

Scientists create nano-size packets of genetic code aimed at brain cancer seed cell

16.7.2018   |   Press monitoring

In a "proof of concept" study, scientists at Johns Hopkins Medicine say they have successfully delivered nano-size packets of genetic code called microRNAs to treat human brain tumors implanted in mice. The contents of the super-small containers were designed to target cancer stem cells, a kind of cellular "seed" that produces countless...

Stanford AI can predict negative side effects of millions of drug combinations

13.7.2018   |   Press monitoring

Nearly 40 percent of Americans over the age of 65 take five or more different drugs, and doctors often simply have to monitor patients to see if any of those drugs combine to create adverse side effects. Drug combinations are a remarkably unstudied area, but as Marinka Zitnik explains, "it's practically impossible to test a new drug in...
