Moss Garden Terrariums, Kokedama (String gardens) and other thoughful plant products.

We have recently added lots of Twig’s collection of Moss Terrariums and Kokedoma to our offerings at Spectrum Scientifics.

Moss Gardens are excellent gifts for people who struggle with indoor plants, or simplyprefer to have low maintenance plants with whimisical displays.  They require almost no maintenance: simply keep them out of direct sunlight and mist them once every 2-4 weeks and you’re all set.

Twig’s terrariums run the gambit of whimsical displasy in lovely containers. They are made on demand so orders may take 5 days to ship, but the folks at Twig have perfected thne art of shipping live plants and guarantee that the plant will arrive healthy and intact.

In addition to Moss Terrariums. Twig also produces Kokedoma (String Gardens) and lovely gift planters which we will cover below.

First let’s look at the Terrariums.

6032First up is the Grazed and Confused which fills and old-style apocethary jar. A pair of model sheep complete the landscape-in-a-jar illusion.

6035The Uncharted Territory displays in a lidded glass bowl, a pair of lost model hikers who have gone off the trail complete the landscape diaroma effect.

6034The Gentle Reminder is a great gift for your loved one as a model loved one (male or female, you pick) holds a sign reminded the other that they are loved. The jar is lovely and has a wooden ball stopper.

Other Moss Terrariums include The Water’s Fine and the Flora and Fauna DIY Terrarium (which includes plants besides the Moss)

Kokedama

Kokedama is a ball of Moss, wrapped in string and displaying an ornametnal or functional plant. Using the string the Kokedama can be hung anywhere in the home to create a lively and attractive bit of living art. Kokedama displays need soaking in water every few days.

6041Twig makes several Kokedama, the most attractive of which is their Orchid Kokedama. This includes the ball, the string, care instructions, and of course and orchid plant. The orchid is an attractive plant even when not in bloom. I

f you are looking for something a tad more functional or aromatic there is the Rosemary & Thyme Kokedama. This plant grows the popular herbs that you can trim off regularly and use for cooking or craft projects.

Also available is a Mint Kokedama for those who like their Ice Tea with a little bit of Mint. 6047

Funky Flora

A great way to say thank you with a lovely plant is to use one of the clever and whimisical Funky Flora plants and planters from Twig. The first and most hilarious is the Thankyousaurus. 6039

This Funky Flora planter is a 12″ x 15″ Dinosaur planter that comes with plants installed.

Also available is the Elephant in the Room Funky Flora, and impressive 12″ x 12″ pachyderm planter.6037

Also available is the Sheldon Turltle Funky Flora.

All Twig products are made on demand and require 5 days to prepare and ship (sometimes less).  Shipping is assured that you will get a live and intact plant. However as the Terrariums are living things their lifespan cannot be guaranteed.

We now have an entire category on our website devoted to Terrariums and otherlive plants for you to peruse. You may find Terrariums not listed in this blog post.

The New AAS T-heater Slim PCR Cycler

In Biotechnology there is a process known as PCR. PCR, or Polumerase Chain Reaction is widely performed through a series of heating cycles that pull apart, duplicate, and fuse back together the two strands of a DNA double helix, PCR creates new copies of DNA that are identical to the original.

Traditional PCR requires the material be heated to about 95C, wherupon the DNA strands seperate, or ‘denature’. The sample is then cooled a bit  so the strands will anneal to ‘primers’, which are short DNA strands designed to bond to specific sections of the DNA strand. The sample is heated slightly more (72C) and  activates an enzyme called polymerase that attaches itself to the end of the primer. The polymerase “extends” the primer’s length based on the original DNA, thus recreating the desired sequence.

During this “extension” step, the polymerase reacts with the original copy to produce a new chain of DNA, thus the name Polymerase Chain Reaction. Since this process happens for both of the original DNA strands, the amount of DNA is doubled after one PCR cycle. Over many cycles, PCR exponentially expands the amount of DNA you were started with.

BIO-RAD Genetics home science kits!

We’ve been waiting for this item for a while, and because of some issues with the manufacturer it took a bit of time to get them in stock, but they are here! Three new products from BIO-RAD, a company mostly known for it biological educational equipment.

We’ll start off strong with the Genes in a Bottle Kit

More Anatomy Models

Previously we covered human body part models we carry, today we will show more models that have more detail of joints, organs, etc.

First is the Bone Tissue Model

5613

This relief model depicts both exterior and interior details of four different human bone structures. Includes the femur, trabecular/spongy bone, compact bone, and blood vessels. It measures 16.5″ x 12″.

Continuing with Bones we have the Bone Structure Model

5614

This bone structure model is enlarged 80x and demonstrates a section of a lemallar bone, along with the normal structure of a tubular bone. This extremely detailed model utilizes cross and longitudinal sections through all of the levels of bone to demonstrate the individual bone components. The model is 10.5″ x 8″ X 6″

Another close up framed model is the Skin Section Model

5619

This model depicts a section of human skin and is enlarged 70X. The epidermis, dermis and subcutaneous layers of tissues are shown in great detail. Representations of sweat glands, hair follicles, receptors, motor nerves, blood vessels, sebaceous glands and fatty tissue are also shown. Mounted on a base.

Moving the magnification out to life size we have the Shoulder Joint Model

5615

This life-size model depicts the mechanics and detailed anatomy of the human shoulder and provides a great opportunity for student and patient learning. This model features portions of the clavicle, humerus, and shoulder blade as well as the glenohumeral and other ligaments that connect each to one another and allow movement.

Move down the arm we have the Elbow Joint Model:

5616

This life-size model depicts the detailed anatomy of the human elbow joint and provides a great opportunity for student and patient learning. This model features the distal portion of the humerus and the proximal portions of the radius and ulna as well as the smooth articular cartilage and surrounding ligaments.

 

 

The SmartDoc Gel Imaging System – take images with your smartphone

In molecular biology, gel imaging is used to document proteins and nucleic acids suspended in various types of chemical gels. Perhaps4062 the most common version of this you might see outside the lab is when it is used in DNA forensics. Many crime shows often have the forensics people waving what look like an X-Ray of a bunch of dots. But in fact these are images created by using electrophoresis equipment.

A big issue with many systems, however, is that to image these systems you have to use expensive equipment, usually a camera device that underlights the sample in  dark chamber. These gel imaging systems can cost thousands of dollars.

But Accuris Instruments have come up with an ingenious solution. Instead of paying for a fully external camera, why not develop a Gel imaging system that employs a camera that almost everyone has on their person – Their Smartphone! So meet the SmartDoc Gel Imaging System.

Safariology: All the rest

So in the first part of Safariology we covered the sets that involve life cycles, be they bee, plant, or frog.

In this part we cover the other sets in the series we shall be carrying. There are only 2 but they are awesome!

First up is Evolution of Man which is a 5 piece series that covers several stages of human evolution:

Safariology: Life Cycle of Plants, Insects and Animals

Safariology is a series of models sets by Safari LTD, who are known for their toy animal kits. Safariology aims at being more educational by producing packs of 4-5 models that show the growth of an animal, insect, or plant. The first example is probably the more popular Life Cycle of the Frog:
