A study has shed important light on migraine development by leveraging cutting-edge imaging technology to gain a new perspective on structures in the brain, which revealed enlarged spaces around the blood vessels in people suffering the condition.

Researchers working with a remote population in the Amazon have found the group experiences extraordinarily low rates of dementia. The study follows on from prior findings that the same group displayed almost no cases of age-related heart disease.

Scientists have managed to watch memories form inside the brains of live fish in real time. And the results were intriguing – synapses formed in one part of the brain while disappearing from another, rather than strengthening as previously thought.

Fatty liver disease is a condition linked to obesity and diabetes, and in turn often leads to further major complications. Researchers have now found a way to reverse the progression of the disease in mice, by quieting an overactive gene.

Lizards can regrow their tails, but the new tail isn't quite perfect. Scientists have now used stem cell therapy to let lizards grow better tails – bones, nerves and all – in an advance that could have implications for better wound healing in humans.

A new study has shown how short spurts of so-called fasting-mimicking diets can bring about a range of benefits in otherwise unhealthy mice, ultimately preventing the buildup of fat and onset of obesity.

A peptide called MOTS-c shows promise in preventing type 1 diabetes, in new tests in human cells in culture and live mice. The peptide regulates the immune system, potentially leading to treatments for type 1 diabetes and other autoimmune diseases.

When objects are being 3D printed, they often have to include supportive structures that are subsequently discarded. A new print bed, however, is designed to eliminate the need for such structures, thus reducing both waste and printing time.

So far as feedstocks for the production of biofuels go, kelp is a highly promising one on many fronts, and a new technology promises to boost its credentials even further by maximizing its exposure to both sunlight and nutrients.

Things can get very chaotic on the ocean floor, making it difficult for underwater robots to keep from being swept away. New research, however, suggests that by copying the structure of the starfish, they could actually be pressed into place.

As a seedling matures into a tree, its trunk and branches become stiffer and stronger. Scientists have now replicated this effect in a photosynthesis-assisted 3D-printing ink, made partially from spinach.

Exercise can be a means to an end, namely better health. Now scientists at USC have studied a hormone that the human body releases during exercise, and found that administering it to even elderly mice improves their fitness and overall health.
