World's deadliest toxin
|
view preview
The deadliest substance known to man is a recently discovered type of botulinum toxin ( botox). The scientists who discovered it haven’t found an antitoxin yet, so they have decided not to publish the gene sequence due to security concerns. The toxin comes from the bacterium Clostridium botulinum and blocks the chemical signals that makes nerves work, causing botulism and death by paralysis. The image shown above is the protein structure of botulinum toxin.

Imagine building the tallest tower
|
view preview
Engineers led by sci-fi writer Neal Stephenson have unveiled plans for the tallest building in the world. Tall Tower would be 24 times the height of Dubai’s Burj Khalifa, considered the tallest building in the world, and would double the maximum heights for commercial airspace, as the designers believe the tower could also be used to launch rockets into space. A building this high poses many structural issues, and we don’t know if it will ever be built.

Aurora borealis
|
view preview
This picture of a green and red aurora was taken on September 26, 2013, from the International Space Station. The colours of the aurora borealis depend on which atoms the solar storm excites. Green auroras appear when charged particles from the solar wind crash with oxygen atoms in Earth’s atmosphere and produce green photons; red auroras occur when the particles collide with nitrogen atoms or when there are lower-energy oxygen collisions, producing red photons.
