An object that has a temperature greater than absolute zero emits some type of radiation. More often than not, objects surrounding us emit radiation in the form of heat that is not visible to the naked ...

Small mechanical systems and optics are interlinked in many ways. People use lasers to create small electronic systems like those found in semiconductors. Increasingly, light plays an important role in ...

From Star Wars to Star Trek, the idea of interstellar travel has always fascinated us. Today, scientists and researchers are looking for ways to turn the vision of interstellar travel into reality. One of ...

Multi-photon microscopy is a useful tool for analyzing in-vivo interactions between photons and living tissues. One of its characteristics is deep tissue penetration, meaning it can get a better look at ...

Adaptive optics is a technology to compensate for distortions in an imaging system. It typically uses a deformable mirror, that deforms to adjust for incoming distortion as the image is taken. It has been ...

When we think about the type of matter that makes up the majority of our universe, we tend to say it is baryonic (stars, gases, galaxies, planets, and dust). While it is true that baryonic matter makes up ...

In modern medicine, the ultrasound is a go-to method for viewing the body’s internal structures, given its non-invasive nature. Ultrasound produces images in real time by relaying high frequency soundwaves ...

How research in photodynamic therapy may lead to new treatments of deadly diseases like cancer. Mesothelioma is a form of cancer that is most often associated with asbestos exposure.  Despite efforts of ...

In grade school, we have all learned that our universe is made up of three elementary particles: protons, electrons, and neutrons. Most don’t know that there is a total of 40 elementary species of ...

Precision agriculture is the practice of micromanaging crops to maximize yield, with the help of sensors, mapping techniques and laboratory studies like spectroscopy. This type of “smart” farming is ...
