Despite scientific evidence suggesting close phylogenetic relationship between chimpanzees and humans, the inclusion of these apes in the genus "Homo" is controversial. Several tools have been used to analyse this issue such as fossils, molecular clock and genome. This work intended to understand the biology teachers' conceptions about…

Often overlooked in many molecular cell biology laboratory and cell culture courses, suspension cells represent an important aspect of molecular cell biology and cell culture. Most primary cell cultures and cell lines are adherent cells which grow in monolayers on surfaces. However, other cells such as hematopoietic cells, certain tumor cells, and…

The study describes the latest recommended and adopted clinical and management practice for children and adults with autistic spectrum disorder (ASD) in Russia and discusses the most recent research work by Russian clinicians and neuroscientists in the field. The study also presents data from the first epidemiological studies on ASD prevalence and…

The change in enthalpy of a chemical reaction conducted at constant pressure is equal to the heat of the reaction plus the nonexpansion work of the reaction, ?H = qP + w[subscript additional]. After deriving that relationship, most general and physical chemistry textbooks set w[subscript additional] = 0 to arrive at the claim that ?H = qP, and…

The University Libraries at the University of New Mexico reconfigured their established library instruction program for biology as part of a broader grant-funded essential-skills workshop series for STEM students. This initiative standardized supplementary instruction through seven inperson and online workshops delivered to students through the…

In this work, we present the results of an undergrad student from the perspective of its first approach as a principal researcher in a project. In order to gain practical experience, one of the options for students that have interest in pursuing a postgraduate program corresponds to a research stay in a laboratory of their selected field…

The development of social media applications has made it an important part of students' personal lives. In this article, we aim to determine whether social media usage is beneficial or harmful to college students through academic performance. Through a survey of biological undergraduates, we found that boys use social media applications more…

Purpose: The purpose of this study was to compare the acute effects of general warm-up (GWU) and GWU plus dynamic stretching (GWU + DS) on endurance running performance in well-trained male runners. Method: The endurance running performances of eight well-trained long-distance male runners were assessed on a treadmill after 2 types of intervention…

Many authors suggest an explicit reflection on the levels of organisation, based on known difficulties related to understanding biological systems. Yet, there is no scientific consensus on the characteristics of biological levels and the quality of their relationships. This review intends to present the state of the current discussion in order to…

Identifying contingencies between constructs in a multi-faceted learning progression (LP) is a challenging task. Often, there is not enough evidence in the literature to support connections, and once identified, they are difficult to empirically test. Here, we use causal model search to evaluate how connections between ideas in a genetics LP…

Undergraduate laboratory exercises addressing aspects of cancer biology such as increased cell proliferation, gain-of-function signaling mutations and tumour formation often rely on tissue culture or even small mammal models. Many departments have limited or no access to these tools, and even well-equipped departments face logistical problems when…

This paper explores 'articulations' or 're-turnings' of ill-/health and energy/fatigue in education, re/configuring bodies and minds as 'body_minds'. The Luxembourg vocational school "Institut Émile Metz" (IEM) thereby serves as a starting point. This institute is analysed 'diffractively' through health education institutes as part of an…

Concept maps can be used in undergraduate biology as ways to visually communicate the relationships among things and events. One strength of concept mapping is that there is not just a single, correct way to compose one, given a list of particular concepts. Nevertheless there seem to be associations among ideas that are expressed frequently while…

The protection of earth's biodiversity requires a sophisticated understanding of how human activities can affect the relative abundances of species in natural ecological communities. Here, we report on an introductory biology laboratory activity in which students quantified biodiversity while investigating one of the most important controls on the…

The initial application of evolutionary theory to the universal practice of music-making in humans was at best marginal and at worst dismissive of non-Western musics. Darwin's biography defines an agenda for musicality in the emergence of human culture that is receiving considerable attention in several disciplines, presenting a robust case for…
