A core set of genes involved in the responses of honey bees to multiple diseases caused by viruses and parasites has been identified by an international team of researchers. The findings provide a better-defined starting point for future studies of honey-bee health, and may help scientists and beekeepers breed honey bees that are more resilient to stress.

“In the past decade, honey-bee populations have experienced severe and persistent losses across the Northern Hemisphere, mainly due to the effects of pathogens, such as fungi and viruses,” said Vincent Doublet, postdoctoral research fellow, University of Exeter. “The genes that we identified offer new possibilities for the generation of honey-bee stocks that are resistant to these pathogens.”

According to the researchers, recent advances in DNA sequencing have prompted numerous investigations of the genes involved in honey-bee responses to pathogens. Yet, until now, this vast quantity of data has been too cumbersome and idiosyncratic to reveal overarching patterns in honey-bee immunity.

Research from McMaster University has found that bacteria in the gut impacts both intestinal and behavioural symptoms in patients suffering from irritable bowel syndrome (IBS), a finding which could lead to new microbiota-directed treatments.

The new study, published today in Science Translational Medicine, was led by researchers from the Farncombe Family Digestive Health Research Institute at McMaster, Drs. Premysl Bercik and Stephen Collins, in collaboration with researchers from the University of Waterloo.

IBS is the most common gastrointestinal disorder in the world. It affects the large intestine and patients suffer from abdominal pain and altered bowel habits like diarrhea and constipation, which are often accompanied by chronic anxiety or depression. Current treatments aimed at improving symptoms have limited efficacy because the underlying causes are unknown.

Dangerous thought.

The scientific world was set ablaze of late as discussions ramped up about the resurrection of the wholly mammoth. I know what you’re thinking: Jurassic Park. Well, not quite — but maybe not that far off, either. Dr. Michio Kaku, professor of theoretical physics at the City College of New York, wonders: what if we could clone the Neanderthal, or a dinosaur, based solely off their genomes?

A 3D bioprinter able to create human skin is already being used to help burns patients and carry out skin testing, Alfredo Brisac, CEO of Spanish bioengineering company BioDan, told Radio Sputnik.

Last month, scientists at Universidad Carlos III de Madrid and the BioDan Group presented a prototype 3D bioprinter that can create human skin suitable for transplantation to patients or for use in cosmetic, chemical or pharmaceutical testing.

One of the first living human organs to be created using bioprinting, the 3D-printed skin is created using bio-inks with living cells that are deposited onto a structure that replicates nature. The bio-ink contains the key elements of keratinocytes, fibroblasts and fibrin, which can recreate the structure of the skin.

BOISE, Idaho (AP) — Three types of potatoes genetically engineered to resist the pathogen that caused the Irish potato famine are safe for the environment and safe to eat, federal officials have announced.

The approval by the U.S. Environmental Protection Agency and the U.S. Food and Drug Administration late last week gives Idaho-based J.R. Simplot Company permission to plant the potatoes this spring and sell them in the fall.

The company said the potatoes contain only potato genes, and that the resistance to late blight, the disease that caused the Irish potato famine, comes from an Argentine variety of potato that naturally produced a defense.

New research describes a novel 3D printing technique for the production of smart materials that may find use in soft-robotics and advanced medicine.

In a recent academic paper the, “striking phenomena” that “can be produced by embedding magnetic particles into polymer with designed patterns,” are described in detail. These phenomena include smart materials with, “tunable elastic properties, giant deformational effects, high elasticity, anisotropic elastic and swelling properties, and quick response to magnetic fields.”

As previously reported by 3D Printing Industry, investigations into smart and meta materials are increasingly using 3D printing techniques.

Scientists at Rutgers and other universities have created a new way to identify the state and fate of stem cells earlier than previously possible.

Understanding a stem cell’s fate—the type of cell it will eventually become—and how far along it is in the process of development can help scientists better manipulate cells for stem cell therapy.

The beauty of the method is its simplicity and versatility, said Prabhas V. Moghe, distinguished professor of biomedical engineering and chemical and biochemical engineering at Rutgers and senior author of a study published recently in the journal Scientific Reports. “It will usher in the next wave of studies and findings,” he added.

Wiring our brains up to computers could have a host of exciting applications – from controlling robotic prosthetics with our minds to restoring sight by feeding camera feeds directly into the vision center of our brains.

Most brain-computer interface research to date has been conducted using electroencephalography (EEG) where electrodes are placed on the scalp to monitor the brain’s electrical activity. Achieving very high quality signals, however, requires a more invasive approach.

Integrating electronics with living tissue is complicated, though. Probes that are directly inserted into the gray matter have been around for decades, but while they are capable of highly accurate recording, the signals tend to degrade rapidly due to the buildup of scar tissue. Electrocorticography (ECoG), which uses electrodes placed beneath the skull but on top of the gray matter, has emerged as a popular compromise, as it achieves higher-accuracy recordings with a lower risk of scar formation.
