Interesting and will be important in brain/ neuro replicating and enhancements.

Memories formed in one part of the brain are replayed and transferred to a different area of the brain during rest, according to a new UCL study in rats.

The finding suggests that replay of previous experiences during rest is important for , a process whereby the brain stabilises and preserves memories for quick recall in the future. Understanding the physiological mechanism of this is essential for tackling amnesiac conditions such as Alzheimer’s disease, where memory consolidation is affected.

Lead researcher, Dr Freyja Ólafsdóttir (UCL Cell & Developmental Biology), said: “We want to understand how a healthy brain stores and accesses memories as this will give us a window into how conditions such as Alzheimer’s disease disrupt the process. We know people with Alzheimer’s have difficulty recalling the recent past but can often readily remember childhood memories, which seem more resilient. The parts of the brain we studied are some of the first regions affected in Alzheimer’s and now we know they are also involved in memory consolidation.”

Imagine shirts that act as antennas for smartphones or tablets, workout clothes that monitor fitness level or even a flexible fabric cap that senses activity in the brain!

All this will soon be possible as the researchers working on wearable electronics have been able to embroider circuits into fabric with super precision — a key step toward the design of clothes that gather, store or transmit digital information.

“A revolution is happening in the textile industry. We believe that functional textiles are an enabling technology for communications and sensing and one day, even for medical applications like imaging and health monitoring,” said lead researcher John Volakis from Ohio State University.

The discomfort and stigma of loose or missing teeth could be a thing of the past as Griffith University researchers pioneer the use of 3D bioprinting to replace missing teeth and bone.

The three-year study, which has been granted a National Health and Medical Research Council Grant of $650,000, is being undertaken by periodontist Professor Saso Ivanovski from Griffith’s Menzies Health Institute Queensland.

As part of an Australian first, Professor Ivanovski and his team are using the latest 3D bioprinting to produce new, totally ‘bespoke,’ tissue engineered and gum that can be implanted into a patient’s jawbone.

So after 40 years of prescribing low fat diets & demonising cholesterol, the largest & longest clinical experiment ever (40 years, 9,000 patients, randomly assigned diets) shows that “Patients who lowered their cholesterol, presumably because of the special diet, actually suffered MORE heart-related deaths than those who did not.”

In other words, if you’ve been cutting on steaks, butter etc. for 4 years or more, you may have INCREASED your mortality rate from heart disease by %8.

Oops?

“DNA base pairing has been used for many years to direct the arrangement of inorganic nanocrystals into small groupings and arrays with tailored optical and electrical properties. The control of DNA-mediated assembly depends crucially on a better understanding of three-dimensional structure of DNA-nanocrystal-hybridized building blocks. Existing techniques do not allow for structural determination of these flexible and heterogeneous samples.”

My own prediction is that we will see singularity with humans 1st via BMI/ BI technology and other bio-computing technology before we see a machine brain operating a the level of a healthy fully funtional human brain.

Since War of the Worlds hit the silver screen, never has the notion that machine intelligence will overtake human intelligence is more real. In this two-part series, the author examines the growing trend towards cognitive machines.

It might be time to rethink fertility treatment.

Here’s the scoop: scientists at Northwestern University 3D printed a functional ovary out of Jello-like material and living cells. When implanted into mice that had their ovaries removed, the moms regained their monthly cycle and gave birth to healthy pups.

The scientists presented their results last week at the Endocrine Society’s annual meeting in Boston.

A major concerned for Lockheed is the long passage of time between the crew’s training and the moment a serious issue does come up during a mission—which could be a few years later. “They may not remember the training. Having the right kind of on-board documentation and flight computer to be able to provide the astronauts the information they need when they need it, is important,” Pratt said. “Not just having the alarm go off but having the alarm go off and the PDF file of the manual come up at the same time. That’s really useful in helping the crew understand how to operate their own vehicle.”

Even though Lockheed Martin’s early habitat concept will service exploration missions near the Moon, the company is always thinking about the manned mission to Mars, which will require a far more advanced successor to their current designs. Engineers will need to go through a few iterations of the concept after the health effects of long-duration human spaceflight are known and as new technology is developed. This is the basis that NASA created NextSTEP on.

The federal space agency is looking for a modular habitat that can grow, evolve and be added to. “New modules are built upon the lessons of the previous modules,” Hopkins said.
