Cameras Could Take Night Photos Without a Flash

Whenever you take a picture in the dark there are options: a flash, a longer exposure or digitally enhancing the final image. But sometimes a flash ruins the dramatic lighting, a long exposure is too slow for fast action and editing in Photoshop is too complicated.

Help is on the way: a team of scientists led by Andras Kis at the École Polytechnique Fédérale de Lausanne in Switzerland have found a material that could make cameras five times more sensitive to light, reducing or even eliminating the need for a flash or a long exposure. The material — made from a mix of molybdenum and sulfur— was used to make a single-pixel prototype sensor that only needed 1/25th of a second to expose a night time streetscape that other cameras would require 1/5th of a second. The sensitivity of the new sensor is fast enough that moving people didn’t get blurred.
It works because molybdenite is much more sensitive to light than silicon, the other material other digital sensors in cameras are made from.

Besides sensitivity, there’s another plus to molybdenite: it’s cheap. Unlike other exotic technologies or semiconducting materials, there’s lots of it around and factories making image sensors out of it won’t need re-tooling.

70% of all red meat consumed worldwide is goat meat!

In the United States alone, the number of goats slaughtered has doubled every 10 years, for the past 3 decades. The reason for this trend is perhaps because of the popularity of goat meat on a global scale. Goat meat is considered kosher, as well as halal, meaning it can be eaten by members of two internationally recognized religions.

The nutritional value of goat meat is substantial, with a similar sized serving of goat meat having one third the calories of beef, and much less fat. First goat cheese, and now goat meat is proving to be a healthy alternative for the flavors of food that we just can't seem to ignore.

Brushing your teeth BEFORE you eat breakfast is healthier for your teeth!

A recent survey revealed that 81% of people were completely unaware that brushing your teeth after you eat a breakfast which includes juice or any sugary foods can actually permanently damage your teeth!

The reason you can suffer from permanent enamel damage is because sugar foods and beverages make the enamel on your teeth weak, and if you brush your teeth immediately after your enamel is weakened, you can damage your precious teeth! So, what should you do?

Dentists recommend brushing your teeth BEFORE breakfast, rather than after. However, you can also lay off the sugary foods in the morning, wait an hour after eating to brush your teeth, or, have some cheese or milk to help balance out the acids in your mouth!

Phytoplankton

Phytoplankton are microscopic marine plants.

• A harmful algal bloom in Lake Erie during the fall of 2006.

Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.

The two main classes of phytoplankton are dinoflagellates and diatoms. Dinoflagellates use a whip-like tail, or flagella, to move through the water and their bodies are covered with complex shells. Diatoms also have shells, but they are made of a different substance and their structure is rigid and made of interlocking parts. Diatoms do not rely on flagella to move through the water and instead rely on ocean currents to travel through the water.
In a balanced ecosystem, phytoplankton provide food for a wide range of sea creatures including whales, shrimp, snails, and jellyfish. When too many nutrients are available, phytoplankton may grow out of control and form harmful algal blooms (HABs). These blooms can produce extremely toxic compounds that have harmful effects on fish, shellfish, mammals, birds, and even people.

Dyson sphere

A Dyson sphere is a hypothetical megastructure originally described by Freeman Dyson . Such a "sphere" would be a system of orbiting solar-power satellites meant to completely encompass a star and capture most or all of its energy output. Dyson speculated that such structures would be the logical consequence of the long-term survival and escalating energy needs of a technological civilization, and proposed that searching for evidence of the existence of such structures might lead to the detection of advanced intelligent extra terrestrial life .
Since then, other variant designs involving building an artificial structure or series of structures to encompass a star have been proposed in exploratory engineering or described in science fiction under the name "Dyson sphere". These later proposals have not been limited to solar-power stations. Many involve habitation or industrial elements. Most fictional depictions describe a solid shell of matter enclosing a star, which is considered the least plausible variant of the idea. In May 2013, at the Starship Century Symposium in San Diego, Freeman Dyson repeated his comments that he wished the concept had not been named after him.

Why do fireflies light up?

Fireflies are sometimes called lightning bugs. Many a child has spent a summer evening chasing them. And maybe you’ve wondered – how and why are these insects able to light up?

The answer is that fireflies contain an organic compound in their abdomens called luciferin. As air rushes into the abdomen, it reacts with the luciferin. A chemical reaction gives off the familiar glow of a firefly. This light is sometimes called “cold light” because it generates so little heat. The firefly can regulate the air flow into the abdomen to create a pulsating pattern.

Some experts think the firefly’s flashy style may warn predators of the insect’s bitter taste. On the other hand, some frogs don’t seem to mind. They eat so many fireflies that they themselves begin to glow. Male fireflies also light up to signal their desire for mates – and willing females attract the males with flashes of their own.
But not all the flashing of fireflies is motivated by romance. While each firefly species has its own pattern of flashing, some females imitate the patterns of other species. Males land next to them – only to be eaten alive.

So the next time you see a firefly, keep in mind that its flickering isn’t just a wonder of the night. It’s also a unique, and sometimes deadly, language of love.

• Bottom line: Why do fireflies light up? It’s because of a chemical reaction between an organic compound in the fireflies’ abdomens – called luciferin – and the air.
