Neural networks have become enormously successful – but we often don’t know how or why they work. Now, computer scientists are starting to peer inside their artificial minds.

A PENNY for ’em? Knowing what someone is thinking is crucial for understanding their behaviour. It’s the same with artificial intelligences. A new technique for taking snapshots of neural networks as they crunch through a problem will help us fathom how they work, leading to AIs that work better – and are more trustworthy.

In the last few years, deep-learning algorithms built on neural networks – multiple layers of interconnected artificial neurons – have driven breakthroughs in many areas of artificial intelligence, including natural language processing, image recognition, medical diagnoses and beating a professional human player at the game Go.

The trouble is that we don’t always know how they do it. A deep-learning system is a black box, says Nir Ben Zrihem at the Israel Institute of Technology in Haifa. “If it works, great. If it doesn’t, you’re screwed.”

Neural networks are more than the sum of their parts. They are built from many very simple components – the artificial neurons. “You can’t point to a specific area in the network and say all of the intelligence resides there,” says Zrihem. But the complexity of the connections means that it can be impossible to retrace the steps a deep-learning algorithm took to reach a given result. In such cases, the machine acts as an oracle and its results are taken on trust.

The MMTP needs your support!

Have you ever considered your destiny may depend upon, you personally? And beyond that, have you considered the destiny of many others may depend upon your actions? People who have changed the world, didn’t have any doubts that the future depended on their actions. Scientists, businessmen and famous public figures didn’t wait until someone did something important for the world. They took responsibility for what was happening around and acted, despite all the difficulties. Are you ready to become such a person? Maybe you too have always wanted to make a significant difference, but didn’t know where to begin? So spend a moment to read the information below.

Today there is a unique project being prepared by a group of scientists, activists and other like minded people from many countries. A project which will give us the opportunity to rescue millions of people from future suffering. The project brings the fight against aging to a global level. Each day people suffer and die from the many diseases associated with aging. Researchers worldwide are engaged in a valiant effort to save countless lives in the near future.

We are currently preparing the first stage of the MMTP project — to test combinations of geroprotectors on mice. The results of this research will be available to the entire scientific community. It’s a big step in this work against the most serious enemy of mankind — aging and its related diseases. And now our project urgently needs the help of motivated individuals. We’re looking for volunteers who are ready to put in the time and effort, to make a future without aging a reality that much sooner.

We are therefore looking for people with experience in different fields. Our project is greatly in need of the following activists:

Copywriters. Are you able to state your thoughts on set subject well? Are you interested in discoveries in the field of regenerative medicine? Do you have a little time and a lot of desire to participate in something really important? If so we really need you!

Autism has diverse genetic causes, most of which are still unknown. About 1 percent of people with autism are missing a gene called Shank3, which is critical for brain development. Without this gene, individuals develop typical autism symptoms including repetitive behavior and avoidance of social interactions.

In a study of mice, MIT researchers have now shown that they can reverse some of those behavioral symptoms by turning the gene back on later in life, allowing the brain to properly rewire itself.

“This suggests that even in the adult brain we have profound plasticity to some degree,” says Guoping Feng, an MIT professor of brain and cognitive sciences. “There is more and more evidence showing that some of the defects are indeed reversible, giving hope that we can develop treatment for autistic patients in the future.”

After 10 years of development, the Wake Forest Institute of Regenerative Medicine has finally unveiled a 3D printer that can craft simple tissues, such as cartilage, into complex shapes suitable for implantation.

The printer uses cartridges filled with biodegradable plastic and human cells bound in gel form, and it can grow muscle, cartilage, and even bone. When implanted into animals, these crafted tissues have been shown to survive and even thrive for an indefinite amount of time.

“This is the first [bioprinter] that can print tissue at the large scales relevant for human implantation,” lead scientist behind the project, Anthony Atala, says in the release. “Basically, once we’ve printed a structure, we can keep it alive for several weeks before we implant it. Now the next step is to test these [printed tissues] for safety so we can implant them in the future in patients.”

Criminal’s favorite new tool for extortion.

Hollywood Presbyterian Medical Center was the target of a ransomware extortion plot in which hackers seized control of the hospital’s computer systems and then demanded that directors pay in bitcoin to regain access, according to law enforcement sources.

Ransomware attacks on business data systems are becoming an increasingly common form of cyber crime. The assault on Hollywood Presbyterian computers occurred Feb. 5, when hackers prevented hospital staff from accessing patient information, according to law enforcement sources, who were not authorized to discuss the details of the investigation. The hackers then demanded an unspecified sum of computer currency.

MIAMI, Sept. 10 (UPI) — The first patient to receive therapeutic delivery of islet cells in a new diabetes study no longer needs insulin therapy to control type 1 diabetes, according to doctors at the University of Miami’s Diabetes Research Institute.

The patient, Wendy Peacock, 43, has been giving herself insulin injections to control diabetes since she was diagnosed with the condition at age 17. Since she had the minimally-invasive procedure on August 18, Peacock has been off insulin, because her body is producing it naturally, and she no longer has the dietary restrictions that accompany type 1 diabetes.

Type 1 diabetes is caused by inadvertent destruction of insulin-producing islet cells in the pancreas by the immune system. While previous experimental treatments that involved the replacement of these cells has allowed patients to live without the need for insulin-replacement therapy for up to a decade, the goal is for better delivery of the cells to make the surgical treatment permanent — effectively curing the condition.
