Stripe pattern differences can be used to distinguish individual adult zebrafish

Plos.org 

by Shinichi Meguro, Takahiro Hasumura

Adult zebrafish are commonly used as disease models in biomedical research, but unlike in other model organisms such as rodents, there is no simple method for distinguishing individuals, even though the importance of individual differences is recognized in such research. We developed a side viewing device that can be used to capture images of stripe patterns and identified eight distinct components of stripe patterns on the caudal and anal fins that allowed us to distinguish individual fish.

Cultural values and digital gap: Overview of behavioral patterns

Plos.org 

by Maral Jamalova

The study uses different statistical techniques to understand the relationship between variables explaining the digital divide and classification based on The Inglehart-Welzel Cultural Map for 2023. To achieve this purpose variables focusing on Digital Penetration (the percentage of internet and social media users and mobile cellular connections), Operating Systems share (iOS and Android), Device Traffic (laptop/mobile phone-based web traffic) as well as Mobile Commerce...

Glomerular filtration rate determined by measuring serum clearance of iohexol in unanesthetized cheetahs (Acinonyx jubatus) with comparison to serum symmetric dimethylarginine

Plos.org 

by Nicholas Lordi, Priya Bapodra-Villaverde, Mark Flint

One of the more common diseases affecting zoo-managed cheetahs (Acinonyx jubatus) is chronic renal disease, which can impact their welfare and ultimately shortens their lifespan. Early diagnosis, for which estimating Glomerular Filtration Rate (GFR) is one such tool, is imperative to help mitigate the negative impacts of this insidious disease. GFR was determined by measuring the serum clearance of iohexol in nine clinically normal,... Читать дальше...

Diversity of Chagas disease diagnostic antigens: Successes and limitations

Plos.org 

by Tapan Bhattacharyya, Niamh Murphy, Michael A. Miles

Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, remains a public health issue in endemic regions of the Americas, and is becoming globalised due to migration. In the chronic phase, 2 accordant serological tests are required for diagnosis. In addition to “in-house” assays, commercial tests are available (principally ELISA and rapid diagnostic tests). Herein, we discuss the discovery era of defined T. cruzi serological... Читать дальше...

Why aphid virus retention needs more attention: Modelling aphid behaviour and virus manipulation in non-persistent plant virus transmission

Plos.org 

by Elin K. Falla, Nik J. Cunniffe

Plant viruses threaten food security and are often transmitted by insect vectors. Non-persistently transmitted (NPT) plant viruses are transmitted almost exclusively by aphids. Because virions attach to the aphid’s stylet (mouthparts) and are acquired and inoculated via brief epidermal probes, the aphid–virus interaction is highly transient, with a very short aphid virus retention time. Many NPT viruses manipulate their host plant’s phenotype to change aphid behaviour to optimise virus transmission. Читать дальше...

Experience-dependent serotonergic signaling in glia regulates targeted synapse elimination

Plos.org 

by Vanessa Kay Miller, Kendal Broadie

The optimization of brain circuit connectivity based on initial environmental input occurs during critical periods characterized by sensory experience-dependent, temporally restricted, and transiently reversible synapse elimination. This precise, targeted synaptic pruning mechanism is mediated by glial phagocytosis. Serotonin signaling has prominent, foundational roles in the brain, but functions in glia, or in experience-dependent brain circuit synaptic connectivity remodeling... Читать дальше...

Warren Buffett, Dave Ramsey, and John Maynard Keynes are Wrong!

Ludwig von Mises Institute 

The so-called great minds in economics and finance claim that gold is a “barbarous relic” or a “shiny,” worthless rock. Gold is neither. Despite the steady attacks on its integrity, gold remains a good place to put one's money.

New iPhones charge faster but nowhere near 45W

Macworld.com 

Macworld

When the iPhone 16 handsets were unveiled last month, there weren’t many surprises. Most of the upgrades had been leaked long before, or accurately guessed by well-informed analysts. But not everything we heard before the event proved to be correct.

One theory, supported by seemingly robust evidence, was that the new phones would bring a substantial increase in wired charging speed, all the way up to 45W if the power brick and other accessories supported it. (The... Читать дальше...
