Researchers utilize the SETI Ellipsoid method to identify potential technosignatures in continuous sky surveys, enhancing detection capabilities. The method compensates for uncertainties in signal arrival times using observations spanning up to a year.
Researchers used Fibonacci's method to calculate the Moon's shape, finding that its poles are half a kilometre closer to its centre of mass than its equator. This information is crucial for applying GPS technology to the Moon.
Researchers have identified specific subtypes of ellipsoid body (EB) ring neurons that regulate sleep in Drosophila. These subtypes, including R3p and R4m neurons, promote daytime sleep and nighttime wakefulness, respectively.
Scientists modeled how different coronavirus shapes affect rotational diffusivity, impacting transmission and infective success. The study found that more elongated shapes result in slower rotation rates, potentially improving attachment to cells.
Researchers developed an efficient technique to compensate for position errors in a spherical near to far-field transformation for long antennas, using minimum near-field measurements. The method achieves accurate reconstructions of uniform samples from non-uniform ones, enabling the evaluation of input data needed for traditional NTFFT.
Researchers at Janelia Research Campus have discovered how fruit flies use a specialized nerve cell system to navigate their environment, involving the activation and suppression of neighboring neurons. The discovery sheds light on the fly's internal picture of the outside world and its cognitive processes.
Researchers have discovered a way to kinetically trap liquids within each other, creating stable systems that can be tailored to specific shapes and flow characteristics. This breakthrough holds promise for applications such as drug delivery, fluidics, and energy storage.
Researchers at University of Pennsylvania discovered that changing particle shape can disrupt the coffee ring effect, a ring-shaped stain left after coffee drops evaporate. By using non-spherical particles, they found that it's possible to eliminate this phenomenon and achieve uniform coating deposition.
A NIST research team has found that using volumetrics can improve the accuracy of CT scans for diagnosing lung cancer, allowing physicians to notice smaller volume changes. This method could potentially cut diagnosis time from six months to four weeks.
Researchers directly observed random walks of ellipsoidal particles suspended in water, revealing non-Gaussian behavior. The study rediscovered forgotten ideas from French physicist Francis Perrin, confirming the effects of rotational-translational coupling on non-spherical particles.
Princeton physicists Paul Chaikin and Salvatore Torquato used M&Ms to investigate the physical principles behind particle packing. They found that oblate spheroids can pack up to 68% of the container's space, exceeding the density of perfect spheres.
