A team of researchers has developed a simplified method to perform the necessary calibration of optical tweezers. Shortening the measurement time helps to reduce the risk of damage to biological samples due to light-induced heating.
Researchers took 3-D printed reconstructions of fossil cephalopods to actual water tanks (including a University of Utah swimming pool) to see how their shell structure may have been tied to their movement and lifestyle.
A new study by the University of Malta and Staffordshire University highlights an urgent need for change in the curriculum and demonstrates how introducing longer, more frequent and more physically intense PE lessons can significantly improve children's weight and overall health. Malta currently has one of the highest rates of obesity worldwide with 40% of primary and 42.6% of secondary school children being overweight or obese.
To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell cultures. It may also prove successful against corona viruses.
How neuronal circuits remodel themselves over time, especially during early development, is a major question in neurobiology. Using mice, researchers from Kyushu University have uncovered a biomolecular mechanism behind the strengthening of connections from neurons called mitral cells. The team found that the protein BMPR-2 is a key regulator of selective stabilization of neuron branching and that strengthening of a branch happens only when neural signals are transmitted.
If you didn't have a brain, could you still navigate your surroundings? Thanks to new research on slime molds at the Wyss and Tufts University, the answer may be "yes." Scientists discovered that the brainless Physarum polycephalum uses its body to sense mechanical cues in its environment, and decides where to grow based on that information. This finding provides a model for understanding different types of cognition, including our own.
Jumping spiders can distinguish living from non-living objects in their peripheral vision using the same cues used by humans and other vertebrate animals, according to a study publishing 15th July 2021 in the open-access journal PLOS Biology by Massimo De Agrò of Harvard University in the United States.
Researchers at the Max Planck Florida Institute for Neuroscience (MPFI) have discovered that the cell adhesion protein IgSF11 determines the layer-specific synaptic connectivity of a distinct class of cortical interneurons.
In lab tests, Imperial researchers have created a metal-based molecule that inhibits the build-up of a peptide associated with Alzheimer's disease.
An international team of researchers recently developed and experimentally demonstrated a spectral-volumetric (SV) CUP system that can simultaneously capture 5D information with a single snapshot measurement.
