Summary: Scientists have designed synthetic molecular motors that can be driven by chemical energy and have intrinsic control over the direction of rotation, simple autonomous motion, and near-perfect unidirectionality. This study demonstrates the potential for future generations of multicomponent machines to perform mechanical functions.

Summary: VPS35 plays a crucial role in tau metabolism and neuropathology, with its overexpression reducing pathological tau in neuronal cells while genetic silencing leads to accumulation. The availability of active cathepsin D mediates the effect of VPS35 on pathological tau accumulation, making it a potential therapeutic target for human tauopathies.

Summary: The study found that environmental conditions were the most common triggers of migraine headache among Sudanese patients, while Acetaminophen was the most commonly used drug for relieving migraine in this population. The majority of patients were female (80%), aged 26-35 years (56.9%), and a significant proportion were housewives (40%).

Summary: This study focuses on the procedural necessity of primary investigations in the Arab countries, particularly in Egypt. It analyzes the position of the Arab procedural legislation and judiciary systems regarding procedural necessity and argues against expanding discretionary powers that may lead to abuse of officials and restrict individual rights and freedoms.

Summary: This study presents a statistical field theory for networks of integrate-and-fire neurons with stochastic spike emission, revealing the impact of spike-driven reset of the membrane voltage on population activity. The study uncovers bistability and fluctuation effects in the mean-field dynamics, as well as the roles of spike resets and recurrent inhibition in stabilizing network activity. It also calculates the phase diagram for inhibitory stabilization and finds that wide regions of parameter space exhibit inhibition-stabilized regime.

Summary: In ocean dynamics, two different treatments are found for horizontal pressure gradient force and gravity, with vertical component being much larger than horizontal in both cases. Horizontal pressure gradient force is considered dominant, while horizontal gravity is completely omitted in oceanography. The importance of horizontal gravity is identified using a non-dimensional C number, with global data showing an unexpectedly large C number around 24.

Summary: Researchers have developed a new tool for establishing solid fuel conversion kinetics from thermogravimetric analysis (TGA) measurements using chemistry-informed machine learning approaches. The derived pyrolysis kinetics accurately reproduce the pyrolysis process for different biomass types and demonstrate advantages in predicting volatiles yield.

Summary: Lesions in the left ventrolateral prefrontal cortex increase the risk of depressive symptoms 6 months poststroke, while lesions within the right hemisphere are unrelated to depressive symptoms. Early prediction factors for poststroke depression include depressive symptoms within the first 4 weeks poststroke.

Summary: A new F-test method for two counts data from the Poisson distribution under classical statistics is proposed in this paper. The test is applicable in situations where the count data is uncertain, in the interval, or indeterminate, and it has been shown to be efficient in application and comparison studies.

Summary: Among the social insects, army ants are unique with their coordinated predation, nomadic lifestyle, and specialized wingless queens. This study reports the discovery of the oldest army ant fossil from the Eocene period, named Dissimulodorylus perseus, and reveals unexpected diversity of now-extinct army ant lineages in the Cenozoic.
