How Do Bees Make Honey

Foraging bees collect nectar from flowers, sucking it up with their tubelike tongues. They carry it back to the hive in one of their stomachs. The nectar is transferred to other bees who “chew” it for about half an hour, mixing it with enzymes from glands in their mouth. Then they place it in hexagonal cells made of beeswax and fan it with their wings to dehydrate it. After the water content is reduced to less than 18 percent, the cells are capped with a thin layer of wax. Capped honey can…

Medicinal Value Of Honey

Researchers has found honey to be a  potent antiseptic and anti-inflammatory Substance. According to The Globe and Mail newspaper of Canada reports: “Unlike the arsenal of sophisticated antibiotics that have hit a wall against antibiotic-resistant superbugs, honey is able to do battle with at least some of them when it comes to infected wounds.” What is in honey that gives it the ability to affect healing? The answer involves the worker bee that gathers nectar from flowers. The bee’s saliva contains glucose-oxidase, a key enzyme that breaks down the glucose in the…

Human Activities Creating Natural Disaters

In the opinion of a number of scientists, human-induced changes in earth’s atmosphere and oceans have made our planet a dangerous place by contributing to more frequent and more severe natural disasters. And the future looks uncertain. “We’re in the middle of a large uncontrolled experiment on the only planet we have,” said an editorial on climate change in Science magazine. So that we can better grasp how human activity might be affecting the frequency and severity of natural disasters, we need to understand a little about the underlying natural phenomena. For…

Coco-De-Mer-The World’s Largest Seed

Coco-De-Mer, discovered in the middle of the 18th century. is a type of palm tree found only in the Seychelles, a small group of islands in the Indian Ocean. The largest concentration of the Coco-De-Mer is found in the Vallée de Mai, on the island of Praslin. These palms can reach up to 100 feet [30 m] in height and are estimated to live for hundreds of years. One fascinating fact about the Coco-De-Mer is that it is dioecious; there are male trees and female trees. For the female to produce fruit, it must be pollinated by a male Coco-De-Mer. So…

Early Childhood Care Critical To Human Intelligence

Advances in brain-imaging technology enable scientists to study brain development in greater detail than ever before. Such studies indicate that early childhood is a critical time for developing the brain functions necessary to handle information, express emotions normally, and become proficient in language. “Brain connections are being wired at an extraordinarily rapid rate in the early years, as the landscape of the brain is shaped by moment-to-moment interactions of genetic information and environmental stimuli,” reports Nation magazine. Scientists believe that the majority of these connections, called synapses, are made in…

Reading to Newborn Babies Makes them Smarter

 Reading to young children has such a powerful impact on the rest of their lives that experts now recommend parents begin doing so when their babies are just hours old,says The Toronto Star.

How is Human Activities Affecting Biodiversity

The term “biological diversity,” or “biodiversity” for short, designates all the world’s species, ranging from the smallest bacteria to the giant sequoias; from earthworms to eagles. All this life on earth is part of one great, interdependent web that also includes nonliving elements. Life depends on nonliving components such as earth’s atmosphere, oceans, fresh water, rocks, and soils. This community of life is called the biosphere, and humans are an integral part of it. Biodiversity embraces all the bacteria and other microbes. Many of these are known to perform vital…
