Scientists discover body’s protection shield

Posted by in categories: biotech/medical, chemistry

Scientists have discovered a way to manipulate the body’s own immune response to boost tissue repair. The findings, published in Current Biology today, reveal a new network of protective factors to shield cells against damage. This discovery, made by University of Bristol researchers, could significantly benefit patients undergoing surgery by speeding recovery times and lowering the risk of complication.

When a is damaged, (either accidentally or through surgery), the body quickly recruits to the injury site where they fight infection by engulfing and killing invading pathogens, through the release of toxic factors (such as unstable molecules containing oxygen known as “reactive oxygen species” e.g. peroxides). However, these bactericidal products are also highly toxic to the host tissue and can disrupt the repair process. To counteract these the repairing tissue activates powerful protective machinery to “shield” itself from the damage.

Now, researchers from Bristol’s School of Biochemistry studying , have mapped the exact identities of these protective pathways and identified how to stimulate this process in naïve tissues.

“Surprising” new insights into link between gut microbiome and aging

Posted by in categories: biotech/medical, life extension, neuroscience

A new study is suggesting a metabolite produced by gut microbes could increase neuron production in the brain, improve intestinal function, and ultimately slow the aging process. Across several compelling mouse experiments the research found the negative effects of aging could be counteracted by enhanced microbial production of a molecule called butyrate.

Investigating the effect of the gut microbiome on aging, the new research first performed gut microbiome transplants between old and young mice. Using fecal transplants, young germ-free mice were colonized with the gut microbiota of older mice. The results were somewhat unexpected as the younger mice colonized with the older microbiomes displayed increased neurogenesis, a process whereby new neurons are produced in the brain.

“We’ve found that microbes collected from an old mouse have the capacity to support neural growth in a younger mouse,” explains Sven Pettersson, lead on the research team from Nanyang Technological University in Singapore. “This is a surprising and very interesting observation…”

Quitting smoking could lead to major changes in gut bacteria

Posted by in category: health

Quitting smoking leads to major changes in intestinal bacteria, according to new research. But just what the changes mean will need further investigation.

The small pilot study, to be presented during the American Heart Association’s Scientific Sessions in Philadelphia, comes in the wake of past research showing a link between bacteria in the gut and cardiovascular health. That past work has shown is associated with a decrease in diversity in the types of beneficial bacteria living in the gut.

For the new study, researchers looked at 26 people who were trying to quit smoking and analyzed their stool samples at the start of the study and again two weeks and 12 weeks later.

The measurements of the expansion of the universe don’t add up

Posted by in categories: cosmology, evolution, physics

Physicists use two types of measurements to calculate the expansion rate of the universe, but their results do not coincide, which may make it necessary to update the cosmological model. “It’s like trying to thread a cosmic needle,” explains researcher Licia Verde of the University of Barcelona, co-author of an article on the implications of this problem.

More than a hundred scientists met this summer at the Kavli Institute for Theoretical Physics at the University of California (U.S.) to try to clarify what is happening with the discordant data on the expansion rate of the , an issue that affects the very origin, evolution and fate of our cosmos. Their conclusions have been published in Nature Astronomy journal.

“The problem lies in the Hubble constant (H0), a parameter which value—it is actually not a constant because it changes with time—indicates how fast the Universe is currently expanding,” points out cosmologist Licia Verde, an ICREA researcher at the Institute of Cosmos Sciences of the University of Barcelona (ICC-UB) and the main author of the article.

An artificial intelligence algorithm can learn the laws of quantum mechanics

Posted by in categories: chemistry, information science, quantum physics, robotics/AI

Artificial intelligence can be used to predict molecular wave functions and the electronic properties of molecules. This innovative AI method developed by a team of researchers at the University of Warwick, the Technical University of Berlin and the University of Luxembourg, could be used to speed-up the design of drug molecules or new materials.

Artificial intelligence and are routinely used to predict our purchasing behavior and to recognize our faces or handwriting. In , Artificial Intelligence is establishing itself as a crucial tool for scientific discovery.

In chemistry, AI has become instrumental in predicting the outcomes of experiments or simulations of quantum systems. To achieve this, AI needs to be able to systematically incorporate the fundamental laws of .

Fuel cell drone makes an epic ocean crossing

Posted by in categories: biotech/medical, drones

Although multicopter drones now are being used to transport medical samples and supplies, their 30-minute (or so) battery life limits their range. This week, however, a hydrogen-powered delivery drone managed a one-hour, 43-minute ocean crossing.

The exercise was the result of a collaboration between Texas-based drone development company Guinn Partners, Georgia-based Skyfire Consulting, the US Department of Health, and drone manufacturer Doosan Mobility Innovation – the latter supplied the aircraft, a hydrogen fuel cell-powered DS30 octocopter.

Utilizing its temperature-controlled payload system, the drone was used to transport live bacteria samples from a hospital on the Caribbean island of St. Croix to a testing facility on the neighboring island of St. Thomas. This involved crossing 43 miles (69 km) of open ocean. Upon successfully reaching its destination, the copter reportedly still had almost 30 minutes of flight time left on its fuel cell.
