Experiments show that what the algorithm picks to show you can affect your emotions. But that’s not all. It also affects political behavior.

Sperms Destroy Cancer Cells by Chemical Injection

Video

A study recently published by Haifeng et al. demonstrated the use of sperms guided by a magnetic source (so called spermbots) to deliver chemical injections to cervical cancer cells. A video of this demonstrations (see below) has been published by New Scientist.

Converting Greenhouse Gases to Rocks

Video

One of the ways scientists are attempting to reduce greenhouse gases is to inject these gases into the ground. Specifically, they are testing injecting them, into basalt which is type of igneous rocks usually forming the first (rock) layer (sandwiched between the sedimentary & gabbro layers) in the oceanic crust basalt and in volcanic regions.

The above video features Iceland and its geothermal plants. Iceland is a heaven for geothermal energy as it lies along the Mid-Atlantic Ridge (MAR) (i.e. where Mid-Atlantic ocean floor is spreading apart in opposite directions forming a ridge). Most notably Iceland lies along the V-Shaped Reykjavik ridge (figure below; Google maps) which is part of the Norther MAR.

Animation of the Italy Earthquake’s Seismic Velocity

Video

A “real-time” animation of the seismic (vertical) velocity of Italy’s 5.5 Mw earthquake that hit between the Aquila and Rieti provinces. The second half of the animation shows the whole country and surrounding area.

Real-time indicates that the video reflects how the waves propagated in real-time. It’s neither slowed down not sped up.

Red color indicates relatively higher vertical velocities indicating the ground is moving upwards while the blue color indicates the lower (negative) velocities indicated a downward movement of the ground. Color intensity refers to the magnitude.
