Vision Care for Children in the Developing World

One of the biggest global health crises we face today impacts more than a billion people. It’s not HIV or heart disease. Malaria or mental health. It’s vision impairment. More than 253 million people are visually impaired and there are 1.1 billion people with near-vision impairment according to a paper published by the Vision Loss Expert Group in the Lancet. But a simple pair of eyeglasses can change the lives of these people dramatically.

Life on the Moon? New study suggests there was a habitability window 4 billion years ago

The Moon is completely uninhabitable and lifeless today – a dusty, dry rock. It has no atmosphere, there is no liquid water on the surface, and, maybe the most important, it has no magnetosphere to protect its surface from solar wind and cosmic radiation. But, according to a new study published in Astrobiology, it may have looked quite different around four billion years ago: its surface was not as dry as it is today, and conditions to support simple life on the Moon existed twice during the early years.

We have an ethical obligation to relieve individual animal suffering

Last winter, unforgettable video footage online showed a starving polar bear, struggling in its Arctic hunting grounds. Because of global warming, the ice was thin and the food supply was scarce. The video generated a wellspring of sympathy for the plight of this poor creature, and invigorated calls for stronger efforts to combat climate change – and rightly so.

Hồ Thuỷ Tiên, an abandoned water park in Vietnam

Hồ Thuỷ Tiên is an abandoned water park in Vietnam. It was built in 2004 in an edge of the Vietnamese city of Huế, to the tune of approximately $3 million dollars. The idea was to create a family water park with amusement rides, slides, pools, shows, and an aquarium. But when the park opened its gates to the public, it was only partially completed.

Why students should learn lessons in nurturing nature?

Education is something which everyone wants to obtain. Everyone needs a perfect and complete education. Children’s always like to spend their time outside instead of being in one room. When we place children outside they start to explore themselves and they love to be within nature. When they are in nature they will be able to nurture more and more and they will be able to develop their individual personality and lead to development. Research shows that the kids who spend time outside with nature will be more happy and energetic. In olden days we have seen in movies and in other sources teachers used to teach lessons outside the classroom. They always prefer a place which is under the tree. They know that the pure and fresh air brings positivity to children’s mind that will make them happy; it will help them to stay fresh in mind, and concentrate on lessons easily. Its main factor is to relieve stress. But as time goes we adopted the new method of teaching in the classroom. Students are seated in one room which is covered with walls. They don’t have another source of knowledge they have to be more materialistic. Education is not only about learning process it also includes adopting mental development and accepting a positive perspective towards life.

4 tips for solar providers to sell more in less time

Solar power is growing by leaps and bounds. In the US, a new solar system is installed every four minutes. Moreover, the falling prices of installing a solar panel system are doing wonders in attracting customers. Between 2009-2013, the prices have dropped by 80%. Previously, a rooftop solar system was available for the price of a luxury car. However, these are now available at the cost of an economy car.

Large Synoptic Survey Telescope will scan the skies for asteroids which threaten Earth

Around 66 million years ago, an asteroid (or a comet) with a diameter of at least 10 kilometers (6 miles) impacted a few miles from the present-day town of Chicxulub in Mexico at around 64,000 kilometers per hour (40,000 mph). The impact triggered a chain of events what it is known today as the Cretaceous-Paleogene (K-Pg) extinction event, also known as the Cretaceous-Tertiary (K-T) extinction, and wiped out three-quarters of the plant and animal species on Earth, including non-avian dinosaurs.

The marvel of LED lighting is now a global blight to health

Light pollution is often characterised as a soft issue in environmentalism. This perception needs to change. Light at night constitutes a massive assault on the ecology of the planet, including us. It also has indirect impacts because, while 20 per cent of electricity is used for lighting worldwide, at least 30 per cent of that light is wasted. Wasted light serves no purpose at all, and excessive lighting is too often used beyond what is needed for driving, or shopping, or Friday-night football.
