New shape-changing 4D materials hold promise for morphodynamic tissue engineering

New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a team of researchers at the University of Illinois Chicago. In a new paper published in the journal Advanced Functional Materials, the research team—led by […]

South African Child Gauge tackles the slow violence of malnutrition

The Children’s Institute at the University of Cape Town (UCT) publishes the South African Child Gauge annually to review the status of children in South Africa and to inform policy and programming. The South African Child Gauge 2020 was launched on 18 February in partnership with the Department of Science and Innovation-National Research Foundation (DSI-NRF) […]

Study explains how light could activate neurons

Human brains have an average of 86 billion neurons. These nerve cells are interconnected at junctions known as synapses, and some neurons have as many as 10,000 such synapses. A key to understanding brain function is to have a better grasp of how this non-logical arrangement of complex neurons leads to specific behaviors and cognitive […]

Five ways boredom could be changing your behaviour, for better or worse

Many of us have probably felt bored at some point in the past year. Restrictions on social gatherings, travel and plenty of other activities may have been necessary to control the pandemic, but have left lots of us with little to do. On the surface, boredom may seem rather trivial; an experience reserved for those […]

Biomedical device can prevent deaths caused by blood clots

New portable technology that visualizes clots forming in flowing blood in a 3-D holographic livestream promises to dramatically improve screening and treatment of stroke, heart attack and coronavirus-induced lung failure. Millions of people around the world die from heart attacks and strokes every year, and 2.5 million people have died due to coronavirus globally since […]

Microscopic behavior of developing breast cells uncovered

An improved high-tech fluorescence microscopy technique is allowing researchers to film cells inside the breast as never seen before. This new protocol provides detailed instructions on how to capture hi-res movies of cell movement, division and cooperation, in hard-to-reach regions of breast tissue. The technology—called multiphoton microscopy—uses infrared lasers to illuminate fluorescently labeled breast cells […]

Gut health and mood genetically entwined

University of Queensland researchers have confirmed a link between depression and stomach ulcers, in the world’s largest study of genetic factors in peptic ulcer disease. By studying health data from nearly half a million people, Professor Naomi Wray from UQ’s Institute for Molecular Bioscience and Queensland Brain Institute and Dr. Yeda Wu from the IMB […]
