In Brief

  • Researchers are finding ways for us to communicate using only our minds, going so far as to give people in separate rooms the ability to send answers to each other without speaking.
  • If we can hone this technology, it could help people with paralysis or other physical disorders regain the ability to communicate or perform physical tasks.

Imagine living in a world in which verbal communication is no longer required, a society in which telepathy is the norm, where people would be able to “speak” to each other using only their thoughts.

Scientists have long been contemplating the possibilities of brain-to-brain communication in humans, and it appears as though their dreams could become a reality within the next year or so. Such a system would be made possible via major advances in the technology that have been achieved via recent trials involving animals.

Great method btw.


Epilepsy is the fourth most common neurological disorder in the United States. Patients who have it are of all ages and it can seriously limit one’s ability to enjoy life. It’s a spectrum disorder which means the kinds of seizures people suffer and how they are managed will vary depending on the patient. Currently about 3 million people in the US are living with epilepsy and experts predict that at least 1 in 26 people will develop epilepsy at some point in their lifetime. While epilepsy is most often treated with anti-seizure medication, there are some patients who have not benefitted from medication. This form of the disorder is called drug-resistant epilepsy and can be very difficult to treat.

There are surgical options, but it’s crucial to have a good picture of the brain’s anatomy before any surgery is undertaken. Currently there are two methods for this. A recent article published by the American Academy of Neurology in the medical journal Neurology, looked at the two methods and revised the guidelines for each. The more common method of mapping the brain before surgery is the intracarotid amobarbital procedure, also known as the Wada test. In this procedure one side of the brain is anesthetized by injecting medication via the carotid artery. It’s invasive, can be uncomfortable and does carry some risk. The other way to get a look at the brain architecture is to use functional MRI scans.

TUESDAY, Jan. 31, 2017 (HealthDay News) — Developing or worsening type 2 diabetes could be an early sign of pancreatic cancer, new research suggests.

Researchers analyzed data from nearly a million patients with type 2 diabetes or pancreatic cancer in Italy and Belgium. Half of all pancreatic cancer cases were diagnosed within a year of patients being diagnosed with diabetes, the findings showed.

The investigators also found that type 2 diabetes patients whose condition deteriorated rapidly requiring more aggressive treatment were also at increased risk for pancreatic cancer.

Nice.


When you think of diamonds, rings and anniversaries generally come to mind. But one day, the first thing that will come to mind may be bone surgery. By carefully designing modified diamonds at the nano-scale level, a Missouri University of Science and Technology researcher hopes to create multifunctional diamond-based materials for applications ranging from advanced composites to drug delivery platforms and biomedical imaging agents.

Dr. Vadym Mochalin, an associate professor of chemistry and materials science and engineering at Missouri S&T, is characterizing and modifying 5-nanometer nanodiamond particles produced from expired military grade explosives so that they can be developed to perform specific tasks. His current research studies their use as a filler in various types of composites.

Mochalin hopes to develop a way to uniformly incorporate the nanodiamonds and form strong chemical bonds between them to help design composite structures that can be used in medical applications, oil drilling bits, polishing and lubricating compositions, and even energy storage systems. Nanodiamonds are the ideal choice for such applications because they are mechanically strong, chemically stable and non-toxic. They can also form bonds with many other materials due to their tailorable surface chemistry.

To learn more about Breakthrough Starshot, visit http://breakthroughinitiatives.org.

On the fifty-fifth anniversary of Yuri Gagarin’s great leap into space, April 12, 2016, Yuri Milner was joined by Stephen Hawking at New York’s One World Observatory to announce Breakthrough Starshot, which will lay the foundations for humanity’s next great leap: to the stars. It was also announced that Mark Zuckerberg joined the board of the initiative.

Breakthrough Starshot is a $100 million research and development program, aiming to establish proof of concept for a ‘nanocraft’ – a fully functional space probe at gram-scale weight – driven by a light beam. A spacecraft like this, equipped with a lightsail, has the potential to reach twenty percent of the speed of light – or 100 million miles an hour. At that speed, it could reach Alpha Centauri, our nearest star system, in around 20 years. Using the fastest conventional rocket propulsion system available, the same journey would take tens of thousands of years.

This new scientific initiative is committed to international collaboration, open access and open data. It aims to represent all of humanity as one world, stepping out into the galaxy within a generation.

Highly sophisticated robotics and ‘bio-printing’ are rapidly changing the face of modern surgery, significantly eliminating the risk of human error and in some cases even allowing doctors to perform procedures remotely, according to experts at Arab Health.

Dr Peter C.W. Kim, vice-president and associate surgeon-in-chief of the Joseph E. Roberts Jr. Centre for Surgical Care at Washington DC’s Children’s National — which has received millions of dollars in donations from the UAE’s government — noted that doctors will soon be able to 3D-print using bio-tissue, such as for an eardrum.

“What our engineers and researchers have done is not only design the plastic with it, but also graft cells onto it,” he said. “This is where we are going. You will (in the future) be able to have organs on the shelf. Instead of harvesting it, you can print it.”

The ancient impulse to procreate is necessary for survival and must be hardwired into our brains. Now scientists from the University of North Carolina School of Medicine have discovered an important clue about the neurons involved in that wiring.

Using advanced deep brain imaging techniques and optogenetics, the UNC scientists found that a small cluster of sex-hormone-sensitive neurons in the mouse hypothalamus are specialized for inducing mice to “notice” the opposite sex and trigger attraction.

This study, led by Garret D. Stuber, PhD, associate professor of psychiatry and cell biology & physiology, and Jenna A. McHenry, PhD, a postdoctoral research associate in Stuber’s lab, identified a hormone-sensitive circuit in the brain that controls social motivation in female mice.

Submarine manufacturer saves major time and cost by 3D Printing a titanium Variable Ballast tank with EBM technology from Sciaky.

The production of an Arctic Explorer submarine was nearly scuppered after the supplier of a component went out of business. To find a solution, however, International Submarine Engineering (ISE) didn’t have to dive too deep. They turned instead to additive manufacturing.

ISE had originally planned to produce the titanium Variable Ballast (VB) tank with traditional manufacturing methods. Their key supplier was an overseas titanium forging facility that previously produced propellant tanks for the Russian space program. But then the supplier went bankrupt.
