A new study by Caltech researchers has shown that the A.I. they created is fully capable of reading handwritten numbers.

Scientists have been able to create a completely artificial neural network by using DNA and a test tube, and the results of this AI experiment have been nothing short of astonishing.

During experiments, this artificial intelligence was able to accurately assess handwritten numbers, with scientists suggesting that this research shows that humans are edging ever closer to taking AI and placing it in organic circuits, as the Daily Mail reports.

A vaccine against HIV is on the horizon after scientists showed a new drug triggered a protective immune response in humans and stopped two thirds of monkeys becoming infected.

In the 35 years since the HIV epidemic began, just four vaccines have been tested on humans, with the best only lowering infection rates by 31 per cent, leading to trials being discontinued.

But in what was described as “promising” and “an important milestone”, an international team of scientists showed that the new vaccine boosted the immune systems of nearly 400 healthy adults.

Canadian researchers have discovered a new and direct molecular mechanism to stop cancer cells from proliferating. In the prestigious journal Nature Cell Biology, scientists from Université de Montréal show that a disruption of a fine balance in the composition of ribosomes (huge molecules that translate the genetic code into proteins) results in a shutdown of cancer cell proliferation, triggering a process called senescence.

“Ribosomes are complex machines composed of both RNAs and proteins that make all the proteins necessary for cells to grow,” said UdeM biochemistry professor Gerardo Ferbeyre, the study’s senior author. Cancer cells grow and proliferate relentlessly and thus require a massive amount of ribosomes, he explained. Growing cells must coordinate the production of both ribosomal RNAs and ribosomal proteins in order to assemble them together in strict proportion to each other.

“We were surprised, however, to find that if the production of ribosomal RNA–protein proportions are driven out of balance in a cancer cell, proliferation can be shut down by in a very simple and direct manner,” said Ferbeyre.

The workings of memory and learning have yet to be clarified, especially at the neural circuitry level. But researchers at Uppsala University have now, jointly with Brazilian collaborators, discovered a specific brain neuron with a central role in learning. This study, published in Neuron, may have a bearing on the potential for counteracting memory loss in Alzheimer’s disease.

When a person with dementia forgets having just eaten dinner, it is due to hippocampus damage. In contrast, the same person can describe in vivid detail a fishing trip to Norway 40 years ago. Both cases entail the use of episodic memory, the brain’s storage of events in which we have been personally involved. Dementia diseases impair the ability to form new memories, especially of events since the onset of the disease.

Researchers at Uppsala University have now, jointly with Brazilian colleagues, found certain neurons in the brain that play a crucial part in learning. The same research group had previously discovered ‘gatekeeper cells’ or, in technical parlance, OLM (Oriens-lacunosum moleculare) cells. These are located in the hippocampus, the brain area known to be active in forming new memories. The new findings from Klas Kullander’s research group show that OLM cells’ activity affects the encoding of memories in the brain.

You’re probably familiar with the feeling of slight disappointment that you may have when a good thing—say, a nice trip—is over. Just as you say that it’s too bad that the experience is already finished, someone will probably say that you had a good time nonetheless; an innocent, fitting expression to cheer you up a little bit. This phrase can be harmlessly used in a variety of circumstances, but there’s one in which it really doesn’t fit at all, yet people keep using it: when somebody dies of aging.

Not quite the same thing

In the summer of 2011, my 99-year-old grandmother was dying. She was relatively fine one day, and then on the next day, for no apparent reason, she was in bed, barely conscious. Throughout the subsequent month, she never got out of bed; all her physical necessities were being taken care of by my aunt, who was assisting her day and night. She was drip-fed for the entire month until her death. The doctors couldn’t really do anything for her, and my aunt, stressed to her limit, was torn between the sight of the non-life her mother was going through and the thought that suspending the drip feed would possibly have been the more humane choice. The drip was never suspended, and eventually, my grandmother died.

A new study published in the journal Cell Development reported that the size of an animal’s pancreatic cells relates directly to the length of its lifespan, with animals that have larger pancreatic cells living shorter lives and animals with smaller cells living longer.

Researchers studied the pancreases of 24 mammals in order to figure out how the organ grows, and what that means for an animal’s lifespan.
