Easy access to nutrients has contributed to the increase in obesity in the human population. But, what is obesity and why isn’t everybody fat? Dr. Stephen O’Rahilly provides a biomedical perspective of obesity, and evaluates which genes could potentially shift the balance towards obesity. As he explains, one becomes obese when the balance between energy intake and energy spent is shifted. Surprisingly, mutations that lead to obesity in humans aren’t in genes involved in metabolism and energy storage, but failure in satiety signals in the brain that result in people eating too much. The excess of energy intake over energy expenditure leads to obesity. What is the consequence of obesity in human health? Physically, obesity can result in lower mobility and sleeping disorders. But, in humans, the link between obesity and metabolic diseases isn’t straightforward. For example, not everyone that’s obese becomes insulin resistant. As O’Rahilly explains, the probability of an obese individual to have a metabolic disease is linked to the capacity of adipose tissue to store the extra fat. Mutations that decrease fat storage in adipose tissue increase the chance of metabolic diseases, like insulin resistance, even when the person is not obese.

There's no shortage of resources to help people change their health behaviors -- but far too often, these resources aren't accessible in underserved communities, says physician Priscilla Pemu. Enter "culturally congruent coaching," a program Pemu and her team developed to help patients with chronic diseases monitor their health with the assistance of a coach from their community. Learn more about how this approach transcends language and cultural barriers -- and could potentially transform health care in America.

Here's a paradox: as companies try to streamline their businesses by using artificial intelligence to make critical decisions, they may inadvertently make themselves less efficient. Business technologist Sylvain Duranton advocates for a "Human plus AI" approach -- using AI systems alongside humans, not instead of them -- and shares the specific formula companies can adopt to successfully employ AI while keeping humans in the loop.

Comparing initial rates to determine the order of reaction is a very common question in Kinetics.
Let's take a look at an example:
The objective is to choose a pair of experiments for comparison where the concentration of a reactant changes and ideally the concentration of other reactants remain constant. This means that any change in the initial rates of the experiments must be due to the change in the concentration of that reactant, and we can figure out the order from there.
1. Order of Reaction with respect to HCl
Comparing experiments 1 and 3, concentration of HCl doubles and there is no change in concentration of sucrose. So the change in initial rates must be due to HCl only. We can work out the change in initial rates to be 2 times. This means when concentration of HCl doubles, initial rate doubles. Therefore order of the reaction with respect to HCl will be order 1. For comparison, if order of reaction is zero, initial rate will remain unchanged when concentration of HCl doubles. If order of reaction is 2, initial rate will increase by 4 times (2^2 times) when concentration of HCl doubles. Since we only have 3 possible orders to consider, figuring out the order of reaction is quite straightforward.
2. Order of Reaction with respect to sucrose
Comparing experiments 1 and 2, concentration of sucrose increase by 1.5 times and there is no change in concentration of HCl. So the increase in initial rates by 1.5 times must be due to sucrose only. Since this is a proportionate increase, order of reaction with respect to sucrose is also order 1. Finally we can write out the rate equation for this reaction to be: rate = k [HCl][sucrose]

Mental disorders are often considered “invisible illnesses,” as the symptoms aren’t always visible. Illustrator and game developer Nicky Case wanted to shed more light on one of the most common mental illnesses – anxiety. With the launch of their new interactive choose-your-own-adventure style game, “Adventures with Anxiety,” Case shows just how clingy the condition can be – by depicting it as a pet wolf, ready to bite at any moment. Case spoke with Storybench, just a few days after the big launch, to discuss interactive story design and making sure we all get enough sleep.

"The AutoCAD 3D eBook was written as a tool to guide and teach you to master AutoCAD. No two students learn at the same pace, therefore the eBooks were written with competency-based modules. The competency-based modules are bite-size pieces that allows you to work at your own pace. They can be used to learn by distance education, correspondence, online, instructor-lead classes, or by individuals teaching themselves to use AutoCAD in their own home or office. This eBook was designed to be used on AutoCAD software that was designed for the Windows operating system. An editable, Pressbooks version of this textbook is under development."--BCcampus website.
