Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change ...

As viral vaccines are increasingly used to meet global health needs, the pharmaceutical industry is manufacturing larger ...

Catalytic function and its efficiency play a significant role in industrial reactions, and consistent reforms are made in the ...

Using a powerful microscopy technique, a team led by researchers at UT Southwestern Medical Center has gained insights into how the body uses vitamin K, an essential nutrient that plays a pivotal role ...

Did you know that a really fast chemical reaction makes riding in a car safer? Most cars have airbags built into the dashboard and steering wheel that can blow up like super-fast balloons during a ...

Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.

Catalysis is the increase in the rate of a chemical reaction by the addition of a reagent — the catalyst — that is not itself consumed. The catalyst works by opening up a route between ...

Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a ...
