Researchers from AMOLF (Amsterdam, the Netherlands) and Harvard University (USA) show how the ability of organisms to move around plays a role in stabilizing ecosystems. In their paper published Feb. 19, 2020, in Nature, they describe how the competition between 'movers' and 'growers' leads to a balance in which both types of bacteria can continue to exist alongside each other.
A multidisciplinary study led by UB researchers has developed a new experimental tool that enables the application of focalized damage on an in vitro neuronal network of only a few millimetres and record the evolution of the whole network. One of the main conclusions is that the network quickly activates self-regulation mechanisms that reinforce the existing connections and restore the functionality of the circuit.
Russian researchers present a smart material with unique properties, which holds promise for express DNA analysis and next-generation drugs against cancer and other serious diseases.
People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. In this week's Applied Physics Reviews, scientists report the development of a new tactile-enhancement system based on a highly sensitive sensor. The sensor has remarkable sensitivity, allowing the wearer to detect the light brush of a feather. This crack-based sensor was inspired by a spider's slit organ.
For the first time, scientists have found a way to reveal the mechanics of the human body's 'steering wheel' -- the subtalar joint.
Like finding a needle in a haystack, Liviu Movileanu can find a single molecule in blood.
Genes are like instructions, but with options for building more than one thing. Daniel Larson, senior investigator at the National Cancer Institute, studies this gene 'splicing' process, which happens in normal cells and goes awry in blood cancers like leukemia.
Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body.
More than half of all cancer patients undergo radiation therapy and the dose is critical. Too much and the surrounding tissue gets damaged, too little and the cancer cells survive.
The top contributor to familial Parkinson's disease is mutations in leucine-rich repeat kinase 2 (LRRK2), whose large and difficult structure has finally been solved, paving the way for targeted therapies.
