Toxicity measurement test.. Its fun to work with Lab mouse


Measures of Toxic Effect

The inherent toxicity of a substance is one of the factors that determines how a material should be handled in the laboratory. Substances may be acutely toxic, chronically toxic, or both.

The albino laboratory rat with its red eyes and white fur is an iconic model organism for scientific research in a variety of fields.  is a rat of the species Rattus norvegicus (brown rat) which is bred and kept for scientific research. Laboratory rats have served as an important animal model for research in psychologymedicine, and other fields.


Total mouse were 10. one of them was an athlete and performed such kind of tasks that made us laugh 😀

Rest of the mouse were in one corner of mouse cage. (may be they were shy :D)

Then a time came when we have to open the mouse cage for performing practical. The same time one of my friend went out of room. She was afraid of those mouse actually 😀

 We took out two of those mouse to measure their body weights. but they were not ready to leave each other 😀

After weighing, we mark them all for making distinction.
It was really a fun by working on these mouse. in fact we were loving these adorable creature. though the ending of this experiment is not bearable but for the sake of new researches and for human welfare we have to perform such experiments. because it is almost impossible to test toxicity of a certain animal on human being 🙂
hope you enjoy 😉

Spider can smile..then why don’t you ;)


The Hawaiian happy face spider (Theridion grallator) has naturally evolved a multitude of patterns in order to confused predators – and many of them strangely enough resemble a yellow smiley face. Scientists believe that having individuals with varying patterns has helped the species avoid predators such as forest birds, but no one’s quite sure why the smiley faces have been so popular.
Smile plzzzz 🙂

Save our innocent bees


Pesticides are killing bees and could be putting our food supply at risk, new research has found. Bees don’t just make honey, they pollinate around one third of the plant-based foods we rely on. But the new study revealed pesticides used in farming are killing worker bees and damaging their ability to gather food, resulting in the collapse of entire bee colonies.

Glow Worm


 

 

This amazing image was taken inside the Waitomo Glowworm caves in Waikato, New Zealand. The caves are famous for their abundant glowworms, which are the larval form of a gnat species (Arachnocampa luminosa) that’s unique to New Zealand. The larval worms glow to attract prey into the silky threads they weave from the roof of the cave – the hungrier they are, the brighter they glow.

 

 

 

Amazon Milk Frog


This is a baby Amazon milk frog (Trachycephalus resinifictrix), a striking amphibian that spends its life in the trees of South America’s Amazon Rainforest and can grow up to 10cm long. The name ‘milk frog’ has little to do with the species’ amazing colouring – it refers to a toxic white fluid their skin excretes when stressed or in danger. Beautiful!

Beluga Whale can copy human voice


A captive beluga whale could mimic human speech, a study has revealed. The beluga named NOC started copying the voices of his handlers in 1984 and managed to lower his vocalisations several octaves to produce garbled phrases. There have been other similar reports of belugas ‘talking’ in captivity and the wild.
