Certain chemical bonds exhibit magnet-like behavior, with one end slightly positive and the other slightly negative. The positive end of one molecule is attracted to the negative end of another, holding them together. Molecules with oxygen bonded to hydrogen, such as wat...
It's a hydrocarbon molecule that gives gasoline the ability to resist detonating prematurely in the engine, which causes engine knocking or pinging during combustion. An octane rating measures the amount of the molecule that is in everyday gasoline. The higher the octane number, the greater the ...
Students examine a demonstration size model of DNA or an alpha helix, and use their fingers to identify which atoms / base pairs are particularly involved in hydrogen bonding within the molecule, causing the helical structure. Students then discuss how the increased UV light because of ozone deple...
If quantum theory is universally true, then any physical system such as a molecule, neuron, neuronal network or an entire mind-brain exists partly in all its theoretically allowed states, or configuration of its physical properties, simultaneously in a "quantum superposition"; informally, a "...

Although vaccination represents the gold standard strategy in viral infection management, a drug-based approach may offer an effective and fast alternative therapeutic tool. Antiviral drugs usually target the virus replication cycle or the host cell biology. Although it has some concerns, the latter ap...
