Human eyes are relatively effective at ‘seeing’ colors. The cells required to do so, known as cone cells, are packed into our retinas in great perfusion. Therefore, we can convert light that bounces off the objects around us into the various colors that they represent. Our cones come in red, green and blue subtypes, but their activation is processed into hundreds of different shades based on the differing proportions of these basic primary light colors that hit our eyes.

The Cretaceous period, particularly the latter half of it, is what many of us may think of as the 'T-Rex era.' It is indeed the specific tract of the Earth’s history in which those massive, predatory dinosaurs were most likely to exist. However, without research on other species that lived at that time, that is all it will ever be to us.

Coffee is one of the world’s most popular commercial plants. The main product, the famous beverage made of its roasted fruits, represented an industry worth several billions of dollars today.

What makes people fall for scams? It is likely that you have been privy to one, such as winning all-paid cruise or vacation, at least once in your lifetime. Could it be simple curiosity, hubris, or (as many people appear to believe) advanced age?

Many 'Back to the Future' series fans will be disappointed at the fact that now, despite living in the ‘future,’ most of the cool technological items depicted in the film aren’t available to the everyday consumer yet!

Look at a slime mold - the last thing anyone would think of is a living thing capable of figuring things out for itself. However, this is not the case at all. Slime molds, particularly true slime molds, which consist of a certain form of an amoeba, need to be able to move around their microenvironment, even if to find food, avoid harmful stimuli and respond to other pertinent factors in their lives.

Many people have probably heard of, or even been affected by, package theft. It is a situation in which deliveries, from services such as Amazon, left on the doorstep by couriers or postal staff members, are stolen from these locations by third parties. A recent survey found that about 3 in every 10 Americans have reported experiencing this form of crime. However, it has also been claimed that law enforcement does little about this problem.

The world’s oldest cave paintings are cultural and scientific treasures for the countries in which they are located. This is because they could give an insight into the earliest signs of human civilization and self-awareness. However, a new study conducted by the University of Kent and University of Edinburgh researchers indicated that ancient cave paintings are, in fact, more than just that.

Meteor strikes on the Earth are incredibly rare. It seems this is just as well as their effects on a planet can be catastrophic. For example, the Chicxulub event, which may have effectively eliminated the dinosaurs and brought about the mammal-dominated age, is strongly linked to such an impact. However, it is apparent that large meteors can do damage, even if they do not hit the Earth. Even ones that remotely enter the atmosphere can wipe out a reasonably large area.

If a flying car doesn't really appeal to you, how about a flying bike? A California company is apparently on the verge of making this dream a reality.

The kilogram has been virtually baked into the standard of measurement known as the metric system, since the 1890s. It is frankly hard to imagine modern-day science without it, as so many papers involve its use and that of its various subdivisions (e.g., grams, milligrams, and nanograms).

“The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.” - Marcel Proust For the first time, archaeologists got a clue of significant importance from the north of Luxor, a city in Upper Egypt. They have discovered evidence of a tilted ramp with two sets of steps and a large number of postholes, on either side, which could have been used to hoist blocks from a quarry, through a sled.
