Explosion at Natanz: Why sabotaging Iran’s nuclear program could backfire

Posted by in category: futurism

If the incident at Natanz was a deliberate act of sabotage intended to set back Iran’s nuclear program, it was dangerously shortsighted.

I bring a bundle of qualities, Okonjo-Iweala pitches at WTO

Posted by in category: finance

Nigeria’s former Finance and Foreign Affairs Minister, Ngozi Okonjo-Iweala, on Wednesday, shared her vision with the World Trade Organisation members for the post of director-general.

Following the nomination stage which closed on July 8, the eight candidates vying for the position started presenting themselves to the 164 States that comprise the WTO on Wednesday.

Other candidates aside Okonjo-Iweala are Abdel-Hamid Mamdouh (Egypt), Amina Mohamed (Kenya), Jesús Kuri (Mexico), Tudor Ulianovschi (Moldova), Yoo Myung-hee (Korea), Mohammad Al-Tuwaijri (Saudi Arabia), and Liam Fox (UK).

Damaged Human Lungs Can Be Repaired by Attaching Them to Pigs, Experiment Shows

Posted by in category: biotech/medical…t-to-a-pig

The sad reality of terminal lung illnesses is that there are simply far more patients than there are donor lungs available. This isn’t just because of the low number of donors, which would be problem enough, but many donor lungs are significantly damaged, rendering them unusable.

By using a new experimental technique, though, such a damaged lung has now been restored to function — by sharing its circulatory system with that of a living pig. This leverages the body’s self-repair mechanisms to exceed the capabilities of current donor lung restoration techniques.

Getting To Know Your Booger Biome

Posted by in categories: futurism, health

The human microbiome—our own personalized bacteria profile—plays a part in our health. The different parts of our body, from our skin to our gut, each have their own microbial profile. A team of researchers decided to explore the bacteria living inside our nose, publishing this week in the journal Cell Reports. Microbiologist Sarah Lebeer, one of the authors of the study, discusses what beneficial bacteria reside in our nose—and how this could be used to create a probiotic for upper respiratory infections.

A team of researchers created a profile of the nose microbiome to help create future probiotics for upper respiratory infections.

A new framework for understanding dynamic representations in networked neural systems

Posted by in categories: biotech/medical, neuroscience

Groups of neurons in the human brain produce patterns of activity that represent information about the stimuli that one is perceiving and then convey these patterns to different brain regions via nerve cell junctions known as synapses. So far, most neuroscience studies have focused on the two primary components of neuron information processing individually (i.e., the representation of stimuli in the form of neural activity and the transmission of this information in networks that model neural interactions), rather than exploring them together.

A team of researchers at the University of Pennsylvania recently reviewed literature investigating each of these two components, in order to develop a holistic framework that better describes how groups of neurons process information. Their paper, published in Nature Neuroscience, introduces a holistic theoretical perspective that could inform future neuroscience research focusing on neural information processing.

“In the past decade or so, neuroscientists have used more sophisticated tools to understand how the represents things that it sees or hears in its environment,” Harang Ju and Danielle Bassett, the two researchers who carried out the study, told Medical Xpress. “Some researchers studied brain representations as single patterns of brain activity, while others studied representations as changing patterns of activity. The aim of our paper was to explore how understanding the brain as a of neural units and their connections could frame the recent developments in a way that helps push the field towards a better understanding of the dynamic nature of neural representations.”

Vision scientists discover why humans literally don’t see eye to eye

Posted by in category: biological

We humans may not always see eye to eye on politics, religion, sports and other matters of debate. But at least we can agree on the location and size of objects in our physical surroundings. Or can we?

Not according to new UC Berkeley research, recently published in the Proceedings of the Royal Society B: Biological Sciences journal, that shows that our ability to pinpoint the exact location and size of things varies from one person to the next, and even within our own individual field of vision.

“We assume our perception is a perfect reflection of the physical world around us, but this study shows that each of us has a unique visual fingerprint,” said study lead author Zixuan Wang, a UC Berkeley doctoral student in psychology.

Discovery of ‘thought worms’ opens window to the mind

Posted by in categories: entertainment, neuroscience

Queen’s University researchers uncover brain-based marker of new thoughts and discover we have more than 6,000 thoughts each day.

Researchers at Queen’s University have established a method that, for the first time, can detect indirectly when one thought ends and another begins. Dr. Jordan Poppenk (Psychology) and his master’s student, Julie Tseng, devised a way to isolate “thought worms,” consisting of consecutive moments when a person is focused on the same idea. This research was recently published in Nature Communications.

“What we call thought worms are adjacent points in a simplified representation of activity patterns in the brain. The brain occupies a different point in this ‘state space’ at every moment. When a person moves onto a new thought, they create a new thought worm that we can detect with our methods,” explains Dr. Poppenk, who is the Canada Research Chair in Cognitive Neuroscience. “We also noticed that thought worms emerge right as new events do when people are watching movies. Drilling into this helped us validate the idea that the appearance of a new thought worm corresponds to a thought transition.”

RNA repair shows promise in reversing mutations underlying a neurological disorder

Posted by in categories: biotech/medical, genetics

Scientists successfully edited RNA in a living animal in such a way that the repaired RNA then corrected a mutation in a protein that gives rise to a debilitating neurological disorder in people known as Rett syndrome.

The advance by researchers at Oregon Health & Science University publishes in the journal Cell Reports.

“This is the first example of using programmable RNA editing to repair a gene in mouse models of a neurological disease,” said senior author Gail Mandel, Ph.D., senior scientist in the OHSU Vollum Institute. “This gives us an approach that has some traction.”
