Upgraded Armor

The most thing we should worry about when entering the lab, and what was drilled into our minds throught all our science classes and our courses laboratory introductory session, was our safety. With regards to germs, microbes, bacteria, viruses etc, and their stunning ability to evolve into a stronger species rather rapidly considering the time-span through which scientists have been practicing science, smart people have managed to use solar energy in such a way that reduces our anxiety around those organisms much more than 70% ethanol and heat. At least in the dental industry, the tools used by dentists have been protected - to an extent - in a method, I personally view as brilliant. "First uses of new solar energy technology: Killing germ ...

Tube-nosed reptile
|
view preview
The Spiny Softshell ( Apalone spinifera spinifera) is also known as the "pancake turtle" because of its rather flat, round, leathery upper shell, or carapace. The long neck and elongated, tubular snout allow this turtle to breathe while almost fully submerged and virtually unseen. Softshells ambush prey by lying concealed in bottom mud.

Can anyone whisper, evolution?
|
view preview
Zookeepers at Central Park Zoo in the US assumed their cotton-top tamarins were falling silent every time someone entered their enclosure, but spectrograms, which provide visual representations of sound, revealed what was really going on. These little monkeys were actually whispering their alarm calls instead of shouting them, which is the first evidence of whispering in a non-human primate species.

Strange looking plants

view preview
The island of Socotra is one of the most isolated non-volcanic landforms in the world. Sitting 240 km east of the Horn of Africa and 380 km south of the Arabian Peninsula, its geographic isolation over millions of years has ensured that a third of its plant species are found nowhere else on Earth. Clockwise from the top are dragon blood trees, desert roses, and a native succulent, Dorstenia gigas. ...

Will the Big Bang be a thing of the past?
|
view preview
Cosmologists have formulated a new theory that suggest the universe didn’t start with the Big Bang. They believe the birth of the universe happened after a 4D star collapsed into a black hole and ejected debris, which helps explain why the universe has an almost uniform temperature.

You big fat 'sea' pig!
|
view preview
Sea pigs are marine animals around 15 cm long that live about 1,000 metres down on the deep sea floor. They are scotoplanes (sea cucumbers) and their 'legs' are actually elongated feet which are used to push food into their mouths. The apparent antennae on the front of the head are also feet, used to tread the deep sea water. They feed on deep ocean mud and thrive on the organic material present there. The sea pigs are not considered as a threat to humans and they are not an endangered species. ...

Picking your way into a lady's heart
|
view preview
The velvety ladybird spider is a fascinating arachnid found in northern and central Europe. They live in burrows with silk trip-wires that help them catch large-sized prey. The males have bright red backs with four black spots and emerge only for a couple of weeks in May to breed. The male will only mate if he manages to avoid all trip wires—if he falls, he may become the meal.

Chimpanzees have a gift for numbers
|
view preview
Watch this video.It turns out that our evolutionary cousins can recall number placement better than people can. In the experiment, the task requires the chimp to touch the numbers in ascending order and he has only seconds to make his decisions. The numerals appeared only for a certain limited duration, and were then automatically replaced by white squares. After touching the number one, the rest of the numbers are obscured by squares, making the chimp reliant on his memory to correctly pick the numbers in the right order. After a whistle sounds, the numbers reappear in different positions, so the chimp has to remember the position of all nine numbers after seeing them only briefly. And the chimp quickly aces the test time and time again, r ...

Who needs painkillers?

People who suffer from congenital analgesia can’t feel pain, and often end up hurting themselves as they don’t know when something is too hot, or making them bleed. Researchers have discovered that mutations in the gene SCN11A are responsible for this disorder, which blocks the transmission of pain signals. ...
