Scientists reveal core genes involved in immunity of honey bees

Posted by in categories: biotech/medical, health

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 , 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.

Intestinal bacteria alter gut and brain function

Posted by in categories: biotech/medical, health, neuroscience

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.

3D printing with high-performance carbon fiber

Posted by in categories: 3D printing, materials

Lawrence Livermore National Laboratory (LLNL) researchers have become the first to 3D print aerospace-grade carbon fiber composites, opening the door to greater control and optimization of the lightweight, yet stronger than steel material.

The research, published by the journal Nature Scientific Reports online on Feb. 28, represents a “significant advance” in the development of micro-extrusion 3D printing techniques for carbon fiber, the authors reported.

Rapid changes point to origin of ultra-fast black hole ‘burps’

Posted by in category: cosmology

Gas outflows are common features of active supermassive black holes that reside in the center of large galaxies. Millions to billions of times the mass of the Sun, these black holes feed on the large disks of gas that swirl around them. Occasionally the black holes eat too much and burp out an ultra-fast wind, or outflow. These winds may have a strong influence on regulating the growth of the host galaxy by clearing the surrounding gas away and suppressing star formation.

Scientists have now made the most detailed observation yet of such an outflow, coming from an active galaxy named IRAS 13224–3809. The outflow’s temperature changed on time scales of less than an hour, which is hundreds of times faster than ever seen before. The rapid fluctuations in the outflow’s temperature indicated that the outflow was responding to X-ray emissions from the accretion disk, a dense zone of gas and other materials that surrounds the black hole.

The new observations are published in the journal Nature on March 2, 2017.

Team puts dark matter on the map

Posted by in categories: cosmology, particle physics

A Yale-led team has produced one of the highest-resolution maps of dark matter ever created, offering a detailed case for the existence of cold dark matter—sluggish particles that comprise the bulk of matter in the universe.

The dark matter map is derived from Hubble Space Telescope Frontier Fields data of a trio of galaxy clusters that act as cosmic magnifying glasses to peer into older, more distant parts of the , a phenomenon known as .

Yale astrophysicist Priyamvada Natarajan led an international team of researchers that analyzed the Hubble images. “With the data of these three lensing clusters we have successfully mapped the granularity of dark matter within the clusters in exquisite detail,” Natarajan said. “We have mapped all of the clumps of dark matter that the data permit us to detect, and have produced the most detailed topological map of the dark matter landscape to date.”
