Wake Forest Institute for Regenerative Medicine scientists (WFIRM) have developed a method to bioprint a type of cartilage that could someday help restore knee function damaged by arthritis or injury.

This cartilage, known as fibrocartilage, helps connect tendons or ligaments or bones and is primarily found in the meniscus in the knee. The meniscus is the tough, rubbery cartilage that acts as a shock absorber in the knee joint. Degeneration of the meniscus tissue affects millions of patients and arthroscopic partial meniscectomy is one of the most common orthopedic operations performed. Besides surgery, there is a lack of available treatment options.

There are many human problems that scientists and engineers have solved by drawing ideas directly from biomechanisms found in other lifeforms, from Velcro to Japan’s famous bullet trains, the Shinkansen. Thus, it should not come as a surprise to know that many remarkable advances in anti-reflective coating were inspired by the peculiar biostructures found in moth eyes.

As mainly nocturnal animals that wish to stay hidden from predators, moths have evolved to develop eyes that are non-reflective. Their eyes have a periodic nanometric structure that makes the eye surface graded, as opposed to polished...

According to new research using data from NASA’s retired planet-hunting mission, the Kepler space telescope, about half the stars similar in temperature to our Sun could have a rocky planet capable of supporting liquid water on its surface.

Our galaxy holds at least an estimated 300 million of these potentially habitable worlds, based on even the most conservative interpretation of the results in a new study to be published in The Astronomical Journal...

One of the main natural components of ayahuasca tea is dimethyltryptamine (DMT), which promotes neurogenesis —the formation of new neurons—according to research led by the Complutense University of Madrid (UCM).

In addition to neurons, the infusion used for shamanic purposes also induces the formation of other neural cells such as astrocytes and oligodendrocytes.

“This capacity to modulate brain plasticity suggests that it has great therapeutic potential for a wide range of psychiatric and neurological disorders, including neurodegenerative diseases,” explained José Ángel Morales, a researcher in the UCM and CIBERNED Department of Cellular Biology.

The study, published in Translational Psychiatry, a Nature Researc...
