Scientists found mitochondria size does not coincide with energy demand in the brain as it ages, potentially causing age-related working memory impairment. Their findings point to mitochondria dysfunction rather than synapse loss as cause for age-relat…

In adolescents, sedentary time may increase heart size three times more than moderate-to-vigorous physical activity, a recent article concludes. The researchers explored the associations of sedentary time, light physical activity, and moderate-to-vigor…

To make human-robot interactions safer and more fruitful, robots should be capable of sensing their environment. In a recent study, researchers developed a novel robotic link with tactile and proximity sensing capabilities. Additionally, they created a…

Twisted molecules play an important role in the development of organic light-emitting diodes. A team of chemists has managed to create these compounds with exactly the three-dimensional structure that they wanted. In so doing, they are smoothing the pa…

In a series of experiments, a team of researchers have compared de novo proteins with random-sequence proteins, looking at their stability and solubility. The results are set to advance basic research in this new field.

The ancestors of modern mammals managed to evolve into one of the most successful animal lineages — the key was to start out small and simple, a new study reveals.

Early diagnosis and treatment of Alzheimer’s disease requires reliable and cost-effective screening methods. Researchers have now discovered that a type of sugar molecule in blood is associated with the level of tau, a protein that plays a critical rol…

Whether wriggling your toes or lifting groceries, muscles in your body smoothly expand and contract. Some polymers can do the same thing — acting like artificial muscles — but only when stimulated by dangerously high voltages. Now, researchers report…

Developing and testing new treatments or vaccines for humans almost always requires animal trials, but these experiments can sometimes take years to complete and can raise ethical concerns about the animals’ treatment. Now, researchers reporting in ACS…
