Using Lasers to Study Proteins
Researchers have come up with a simple, low-cost way of studying cellular proteins using a laser. The method may help to develop new drugs intended to treat disease in humans.
Many drugs used to treat diseases function by communicating with proteins located in the outer walls of our cells that in turn communicate instructions to the cell itself. Studying these proteins, however, is difficult because isolating them usually impairs their functioning. A method of study using lasers, however, may make the process easier. "Their process is called back-scattering interferometry (B.S.I.). The sample is deposited into a microscopic liquid-filled chamber made of glass and is then illuminated by a laser. Light reflected from it forms an interference pattern that can be captured by a camera."

Here are 7 often-overlooked World Heritage Sites, each with its own history.
- UNESCO World Heritage Sites are locations of high value to humanity, either for their cultural, historical, or natural significance.
- Some are even designated as World Heritage Sites because humans don't go there at all, while others have felt the effects of too much human influence.
- These 7 UNESCO World Heritage Sites each represent an overlooked or at-risk facet of humanity's collective cultural heritage.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
A new method promises to capture an elusive dark world particle.
- Scientists working on the Large Hadron Collider (LHC) devised a method for trapping dark matter particles.
- Dark matter is estimated to take up 26.8% of all matter in the Universe.
- The researchers will be able to try their approach in 2021, when the LHC goes back online.
