Used Microscopes

Used and refurbished or secondhand microscopes are old but perfectly working microscopes which are sold at discount or lower rates. These microscopes will have 20% to 60% price reduction compared to new ones. Used microscopes usually come with one year warranty/guarantee. Used microscopes are most suitable for schools and other institutions, where the chance for damaging laboratory equipment is higher.

Mosquitoes and Malaria

The bites of the common British species of mosquito (Culex pipiens) cause little more than irritation and swelling. In many tropical countries, the Middle East and Southern Asia, species of mosquito in the genus Anopheles transmit the disease malaria.

For Us It's Life - But For Most It's Science Fiction

If you do it right, it's fun. You immerse yourself in that stuff. If it happens to be science, and more specifically physics, you can get slightly off the mainstream thinking and vocabulary. Some situations can become funny then...

What Are the 39 Types of Sharks Known to Harm Humans?

Historians and the Scientific Approach

The chief purpose of these efforts was, however, not the study of history for its own sake but for the utilitarian purpose of “learning from the past.” The dissatisfaction of historians with such accounts is perhaps partially responsible for the negative attitude of most, or at least many, historians toward the achievement of scientific thinking and their failure to explore the possibilities which a scientific approach has to offer.

Solar System FAQs

The solar system form was formed about 4.5 billion years ago from a massive cloud. The massive cloud contained hydrogen, helium, and pinches of heavier elements such as oxygen, carbon, nitrogen, silicon, and iron. The materials in the massive cloud clumped together and the largest clump became a prostar. Compression of the prostar due to gravity caused the fusion of hydrogen into helium. This gave birth to the sun. In the inner hotter regions of the cloud, heavier elements of dust grains came together to form Mercury, Venus, Earth and Mars. In colder regions away from sun, frozen water, methane, and ammonia came together so quickly that their gravities attracted the nearby hydrogen and helium gases. These gases became the main ingredients in Jupiter, Saturn, Uranus, and Neptune.

Fingerprinting in Forensic Science

Fingerprints collected from a crime scene, or from items of evidence from a crime, can be used in forensic science to identify suspects, victims and other persons who touched the surface in question. Fingerprint identification emerged as an important system within various police agencies in the late 19th century. This system replaced anthropometric measurements as a more reliable method for identifying persons having a prior record, often under an alias name, in a criminal record repository. The science of fingerprint identification stands out among all other forensic sciences for many reasons because of its superiority and reliability.

Forensic Science Careers

There are various specializations one can look forward to as a Forensic Scientist. Some of them are mentioned in the lines to come. Medical examiner is one such field. He requires a medical degree therefore; a residency should be selected that provides a forensic emphasis. A chemistry or biology degree at the undergraduate level is a good majoring option. If at FSU, one takes the crime detection and investigation course as undergraduate electives, one would not have an opportunity for this course at medical school. The forensic odontologist has similar educational requirements as the medical examiner except in dentistry wherein, they generally are dentists who practice as consultants rather than as full-time forensic scientists.

New Scientific Hare Krishna Website

Most people today have been led to believe that science can explain – or soon will explain – all natural phenomena – including the origin of life and the universe. Not many of them get to know that this notion is a belief that is only a few centuries old. Or that is being increasingly challenged by scientific research. 'The Hare Krishna Views On Science' website will systematically present the pioneering research that promises to herald a spiritual revolution within science.

Biology-Insects-Locusts

Locusts are a group of grasshoppers which periodically form dense swarms and cause extensive damage to crops. Locusts live in warm countries such as Africa and India. The locust develops by a process called incomplete metamorphosis, i.e. there is no larval or pupal stage. The eggs hatch into nymphs which resemble the adult insect but they have no wings.

Biology-Insects-Termites-Macrotermes bellicosus

Termites are sometimes referred to as 'white ants,' but they are not ants and are not related to them. They are most abundant in tropical and sub-tropical countries where, in some cases, their ‘nests give rise to large, prominent mounds. All termites form extensive colonies with one egg-laying queen and hundreds or thousands of workers.
