Deep learning has been making it possible for powerful machines to approximate and imitate abilities and techniques once thought to be uniquely human. Mathematicians have struggled to explain how they work so well and may now get some answers by looking outside mathematics and into the nature of the universe.
D esigner therapies are treatments tailored to a specific disease, and nowhere is the need greater for new therapies than in a group of nervous system disorders, known as “neurodegenerative diseases.”
Many of these diseases are common and well-known, such as Alzheimer’s or Parkinson’s disease. However, some are very rare, genetic disorders that are the consequence of a defective gene. In all these diseases, a mutant protein that misfolds causes the degeneration and death of neurons. One effective therapeutic strategy is to prevent the rogue protein from ever being made.
Spinocerebellar ataxia type 7 (SCA7) is one such disease in which nerves in different parts of the brain, including the eye, degenerate, which leads to blindness and difficulty walking, speaking, and balancing. SCA7 is dominantly inherited — which means that you just need one bad copy of the mutation to cause disease. The disease occurs when a short section of DNA that encodes ataxin-7 gene is erroneously repeated — like a word in a book printed two or three times. In this case, three chemical units of the DNA sequence — C-A-G — are repeated over and over.

Before we get started, it’s essential to understand that astrophotography takes time and practice in order to achieve good results, so don’t get frustrated if you don’t nail it on the first go.
When it comes to photographing the night sky there isn’t an exact setting which is going to achieve the same results across the board. This is due to the amount atmospheric light which is available in your area. So in order to help get you started, I’ve decided to write a guide on “how to photograph the stars.”
The aim is to shed some light on the type of equipment you will need and give you a general starting point for where your settings ‘should’ be so that you can head out into the night and have some fun with it.

New research suggests that exposure to childhood adversity is associated with reduced cognitive control and alterations in key brain networks. The findings, which appear in the journal Social Cognitive and Affective Neuroscience, could help explain the link between childhood adversity and depression.
“My work focuses on how we can use objective biomarkers to aid in clinical decision making,” said study author Scott A. Langenecker of the University of Utah.
“One challenging clinical decision point is what to do when individuals have recovered from a depressive episode. Do we continue treatment? Do we exercise regular check-ins? Or do we just wait and see?”
One Grade 11 student’s summer research at the University of Alberta has the possibility to change how industry leaders extract diamonds from rocks.
As part of a six-week internship called the Wisest Summer Research Program, students get the chance to spend their summer doing research at the university.
Hamdi Ali spent this summer at the university’s Earth and Atmospheric Sciences department as part of the internship program. She had the chance to work with various researchers in the geology department for six weeks.

This is the farthest away that black hole wind has ever been known to extend.
Astronomers studying the universe’s first light — the light from the first stars, which ignited nearly 14 billion years ago, according to the European Southern Observatory (ESO) — have made an unexpected discovery.
While scouring the distant cosmos with the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile, the scientists came across a streak of thermal wind spewed from a far-flung black hole, which had traveled a staggering distance from the galaxy where it originated.
