Bisphenol A (BPA) is a synthetic compound that serves as an important component in plastics. Plastics made with BPA are usually clear and tough, and can be used in a variety of common consumer goods, such as plastic water bottles, food storage containers, and certain baby bottles. Due to its versatility, an estimated 4 million tonnes of BPA-derived chemical were produced in 2015, making it one of the highest volume of chemicals produced worldwide. 

For some time, BPA has been a popular topic in the media due to its undesirable effect on human health and the environment. In fact, back before BPA was every used in manufacturing, its first purported benefit was as an artificial estrogen. Due to its chemical structure, BPA is classified as a " ...

A non-Newtonian fluid is a fluid with properties that differ in any way from those of Newtonian fluids - it changes its viscosity almost instantly under stress, so you can punch it as a liquid and it’ll turn into a solid (watch the video below), and you can literally walk across a pool of it. On the contrary, a Newtonian fluid is defined as the perfect fluid, where its viscosity is influenced mostly by its temperature and pressure. So if you have water at a moderate temperature and pressure, it will continue to act like a liquid no matter how much you punch it. Depending on how you manipulate it, the fluid-like substance can change states from a liquid to a solid, but how this happens has remained a conundrum amongst physicists.

An antioxidant derived from grapes, known as resveratrol, could work as an acne treatment by inhibiting bacteria growth. Researchers have found that combining acne medication with the antioxidant makes the drug more effective. Now you may apply grapes on your face ...

Using high-resolution atomic force microscopy, a hydrogen bond has been imaged for the first time. This technique is quite similar to the one used to photograph bonds breaking and reforming that was announced earlier this year.
