Heterogeneous Mixture Definition

While the term "heterogeneous mixture" sounds like it could be a complicated concept, in reality, it is actually quite simple. A mixture is made up of two or more substances, and in a heterogeneous mixture, those substances are not uniformly distributed, meaning that the substances that make up the mixture can be distinguished from one another upon examination.

Probiotics: Potentially Problematic Or Possibly Pointless

A recent study performed by scientists from the Weizmann Institute of Science in Israel was conducted to determine the effects of probiotics on the human gut. Unlike other studies, which measure the bacterial content of fecal samples to approximate the composition of bacteria living in the gut, this study used endoscopies and colonoscopies to directly measure the gut microbiome of participants. One portion of the study looked at the results of a probiotic taken by participants with typical gut microbiomes. Many...

Does Microdosing LSD Stimulate Creativity And Productivity?

Self-prescribed microdosing of LSD has become a growing trend for both dealing with mental health states like depression, and in trying to boost creativity and productivity in areas like software development in Silicon Valley. Individuals who have tried the LSD microdosing approach report various results, but so far, relatively little actual scientific research has been done to study the effects of microdosing LSD on the brain, on moods, and on mental focus and ability. That's all about to change. Beginning this...

A Russian Jurassic Park Is Coming Soon To Siberia

Untold numbers of ancient corpses lay beneath the permafrost in Siberia. Preserved by the icy soil of the region, the genetic material found in the animal remains are the key to better understanding pre-historic life and even to perhaps reviving it. A new research institute to be built in Russia hopes to make those discoveries and more. Next week, from the 11th to the 13th of September, at the 4th Eastern Economic Forum, a proposal seeking further investment will be made...

3D Printed Bionic Eye Prototype May Help In Restoring Sight

The development of functional bionic eyes is currently an unfulfilled objective in the field of prosthetics. Such a development would be used to help improve vision for the visually impaired and one day to restore sight for the blind. The 3D printed bionic eye prototype developed by the McAlpine group from the University of Minnesota is an incremental but important step in the right direction. The McAlpine group is a mechanical engineering group that focuses on developing and synthesizing functional materials...

The Formula For Molarity

The molarity formula is one of the building blocks for understanding chemistry and chemical reactions. Being able to calculate the concentration of a solution is an important and basic piece of knowledge for a chemist. Calculating the molarity of a solution or using the equation for molarity to determine the quantity of a solute that must be weighed out in order to prepare the appropriate solution concentration is something that a chemist does multiple times a day. Molarity is a...

Verb Examples: Identify The Types Of Verbs

Verbs are best learned with examples as it can often be confusing to know which one to use and when. As a part of speech, a verb is a class of word that indicates an action or occurrence, or a state of being, of an object or living being. A dynamic verb is an action or occurrence verb, and a stative verb describes a state of being. All full sentences include at least one verb. Verbs are typically called "action words", but...

Lodestone: Definition And Magnetic Properties

Lodestone is a chunk of magnetite that has become naturally magnetized. The name lodestone comes from the Middle English term "lode" meaning way or journey, making the meaning of the term lodestone to be a stone that leads the way. Lodestone has a unique definition partially lending to the magnetic properties found within this unique stone. The term reflects one of the earliest uses of lodestone as a natural magnetic compass, which was used heavily in navigation. [caption id="attachment_28563" align="aligncenter"...

Ancient Cheese Found Preserved In Egyptian Tomb

Hidden by the sands of time in a cracked clay jar, a dried and chalky white substance wrapped in a bit of canvas waited to be discovered. Finally, the jar was unearthed by archaeologists who were exploring the rediscovered tomb of Ptahmes near Cairo. A chemical analysis of the substance was requested. The white material was identified as cheese and at over three thousand years old, it is one of the oldest pieces of solid cheese found belonging to the ancient world....
