What Makes Humans Different? A New Window Into the Brain

The human brain’s function is remarkable, driving all aspects of our creativity and thoughts. However, the neocortex, a region of the human brain responsible for these cognitive functions, has a similar overall structure to other mammals.

Researchers from The University of Queensland (UQ), The Mater Hospital, and the Royal Brisbane and Women’s Hospital have shown that changes in the structure and function of our neurons may be the cause of the human brain’s increased processing power.

Study Reveals Brain’s Finely Tuned System of Energy Supply

The experiments demonstrated that the blood cells can sense when the environment outside the capillaries is low in oxygen – which occurs when neurons take up more oxygen to generate energy – and respond by rushing to deliver more. They also observed that this response if very rapid, occurring less than a second after oxygen is pulled out of the surrounding tissue.

This phenomenon is unique to the capillaries because of their size. The thin walls of the microvessels mean that the oxygen levels in adjacent brain tissue are mirrored within the capillaries, which can signal to red blood cells to spring into action.

The findings could have implications for a number of neurological disorders, including Alzheimer’s disease. It has been observed that blood flow in the brains of people with the disorder is impaired when compared to healthy brains. The difficulty in delivering the oxygen necessary for neuronal activity may help explain the cognitive difficulties that are one of the hallmarks of the disease.

A breakthrough 3D-printed material incredibly strong and ductile

It’s all thanks to nanoclusters.

A new nanoscale 3D printing material developed by Stanford University engineers may provide superior structural protection for satellites, drones, and microelectronics.


A dual-phase, nanostructured high-entropy alloy that has been 3D printed by researchers from the University of Massachusetts Amherst and the Georgia Institute of Technology is stronger and more ductile than other cutting-edge additively manufactured materials. This discovery could lead to higher-performance components for use in aerospace, medicine, energy, and transportation.

High entropy alloys (HEAs), as they are called, have gained popularity as a new paradigm in materials science over the past 15 years. They allow for the creation of a nearly limitless number of different alloy designs since they include five or more elements in nearly equal amounts. Brass, carbon steel, stainless steel, and bronze are examples of traditional alloys that mix a principal element with one or more trace elements.

Scientists have just made a breakthrough for a potential glioblastoma drug

People affected by the lethal glioblastoma cancer only live for 12–18 months after diagnosis.

A global trial that began in 2007 has confirmed that a vaccine for the treatment of the most lethal brain cancer can give patients years of extended life.

“This is a potent molecule that’s very exciting to us in terms of its potential for deployment against glioblastoma,” said Steve Kay, Ph.D., the senior author of the study.
